All major components are manufac t ured by Eaton, establishing one source of responsibility for the equipment’s performance and ensuring high standards in quality, coordination, reliability and service.A complete line of Eaton switches and fuses is available:■■38 kV voltage class■■600 A continuous loadinterrupting ratings■■Non-fused or fused with current limiting or boric acid-type fuses■■Manual or motor operated■■Indoor or outdoor non-walk-in enclosures■■Single switches and transformer primary switches■■Duplex loadbreak switch arrange m ents for selection of alternate feeds■■Lineups with main bus■■Standard arrangements with auto m atic transfer control systems (two sources feeding one bus or two sources feeding two buses on a split bus with tie switch) Standard design configurations for:■■NEMA T pads for cable lugs■■Surge arresters■■Instrument transformers■■Control power transformers■■Power Xpert T and IQelectronic metering■■Other auxiliary equipmentOutdoor Duplex with Customer MeteringApplication DescriptionEaton’s Load Interrupter T ype MVSmetal-enclosed switchgear provides safe,reliable switching and fault protectionfor medium-voltage circuits rated to38 kV. T he MVS switch is ideal forapplications where high duty cycleoperation is not required.MVS switchgear has the advantage oflow initial cost inherent in switch designswhile offering the characteristics mostvital to safety and coordination.The MVS switch’s quick-make, quick-break mechanism provides full-loadcurrent interrupting capability whilefuses provide accurate, permanentlycalibrated short circuit detecting andinterrupting capabilities. Visibility ofactual blade position improves safetyby giving positive assurance of circuitde-energization.Standards and CertificationsEaton’s MVS load interrupter switchgearmeets or exceeds the requirements ofthe following industry standards:■■IEEE T Standard C37.20.3■■ANSI C37.57■■NEMA SG5■■Canadian Standard CAN/CSA RC22.2 No. 31Type MVS switches meet or exceedthe requirements of the followingindustry standards:■■IEEE Standard C37.20.4■■ANSI C37.58■■ANSI C37.22■■NEMA SG6■■Canadian Standards CAN/CSA C22.2No. 193 and CAN/CSA C22.2 No. 58Load interrupter switches should notbe used to interrupt load currents abovetheir interrupting rating of 600 A, asthey are not designed nor tested forinterrupting fault currents on electricalsystems . Optional fuses can be providedfor phase overcurrent protection .3838150150600–1200600–12004050.46581.92531.5Switch MechanismThe quick-make, quick-break mecha n ism uses a heavy-duty coil spring that provides powerful opening and closing action. T o close the switch, the handle is inserted into the spring charging cam, then rotated upward through an angle of 120 degrees. This action charges the operating spring, as the mechanism is forced past toggle. The stored energy of the spring is released and transferred to the main shaft that snaps the switch closed.As a result of the over-toggle action, the blades are moved independently of the operator. It is impossible to operate the switch into an intermediate position.To open the switch, the handle is inserted into the spring charging cam and rotated downward through 120 degrees resulting in charging of the operating spring,then releasing its stored energy in similar sequence.Quick-Break DE-ION Arc InterruptionWith the switch closed, both main andauxiliary (flicker) blades are closed, andall of the current flows through the mainblades. T he flicker blades are in the closedposition in the arc chutes, but are past thearcing contacts and thus carry no current.As the main blades open, current istransferred momentarily to the flickerblades, which are held in the arc chutesby high pressure contact fingers. T hereis no arcing at the main blades.When the main blades reach a pre-determined angle of opening, a stoppost on the main blades prevents furtherangular movement between the mainand flicker blades. T his starts the flickerblades out of the high pressure contactsin the arc chutes and as contacts arebroken, the flicker blades are snappedinto position by their torsion springs.The heat of the arc, meanwhile, releasesa blast of de-ionizing gas from thegas-generating material of the arc chute.This combination of quick-break andDE-ION action quickly extinguishes thearc and the circuit is safely de-energized.A non-fused switch has the ability to closeand latch four times when rated 40 kA,and one time when rated 61 kA, andcontinue to carry rated current thusadding a large margin of integrity tothe electrical system.Bus Insulation SystemAll bus runs are supported using a highstrength and high creep, finned supportproviding in excess of 24.00 inches(609.6 mm) for 38 kV, of creep distancebetween phases and ground. T he moldedhigh track-resistant fins are constructedas standard of Aramid nylon or optionalCycloaliphatic epoxy.■■Significantly superior bus bracingthan standoff type A20 insulators■■Significantly increased creep distancephase-to-phase and phase-to-ground■■Improved endurance fromfault incidents■■Minimizes bus system failures dueto tracking■■Eliminates additional groundplanes in the switchgear for bussupporting systemsBus SupportFigure 8.3-1. Switch OperationBoth Blades Disengaged Main, Flicker BladesEngagedMain Blades Disengaged,Flicker Blade EngagedDuplex Switch ConfigurationTwo MVS load interrupter switch sections can be used to provide cost- effective source selectivity with a common load side bus feeding one load (fused or nonfused). Key interlocks are a standard feature provided to per m it only one switch to be closed at a time and prevent opening any switch door unless both switches are open.Figure 8.3-2. Typical Duplex Switch Configuration with One K1 Key— Dimensions in Inches (mm)Loadbreak Switch with Grounding Jaw The loadbreak switch can be supplied with optional grounding jaws for auto-matic grounding of the load circuit. When the switch is opened, the switch main blades engage grounding jaws to ground the load circuit. This feature cannot be used in a duplex switch configuration . The ground jaw option is available at38 kV. It is meant for applying a static ground, and is not rated for carrying fault currents.Figure 8.3-3.

Typical Section View of Feeder Switch with Optional Grounding Jaws— Dimensions in Inches (mm)ConstructionT ypical Switch with Front Door Opena Switch MechanismQuick-make, quick-break storedenergy operation.The opening and closing of the switch blades is done by the operating spring.An operator’s actions only charge and release the operating spring.The switch blades cannot be operatedin any intermediate positions. Duringthe closing operation, full clearancebetween blades and stationarycontacts is maintained until theswitch mechanism goes over toggle.The switch mechanism has onlymetal-to-metal linkage—no chainsor cables are used.Arc interruption takes place betweencopper-tungsten tipped auxiliary(flicker) blade and arcing contacts witha DE-ION T arc chute; no arcing takesplace between the main blades and the stationary contacts to prolong the lifeof the main blades.Blow-out forces cannot be transmit t ed to the operating handle.b■Provisions for Padlocking DoorHandle not visible in the photo.c■Inspection W indowA large 8.00-inch x 16.00-inch(203.2 x 406.4 mm) gasketed,rectangular, high impact viewingwindow permits full view of theposi t ion of all three switch bladesthrough the closed door.d■Full Height Main DoorThe door has a return flange and tworotary latch-type handles to providelatching members held in shear.

T ests were performed to substantiate all published ratings in accordance with ANSI, IEEE, CSA and NEMA standards.The testing program included tests of:■■Basic impulse levels■■Momentary withstand■■Short-time withstand■■Fault closing■■Load interrupting at various loads, various power factors■■Mechanical life tests■■Temperature rise testThese tests verified not only the per-formance of the switch and integrated switch-fuse assembly, but also the suitability of the enclosure venting, rigidity and bus spacing.The mechanical life test subjected the MVS switch to a number of no load cycles greater than the requirements tabulated in ANSI C37.22 standards. T here were no moving or current carrying part failures as a result.The Fault Close and Load Interrupting test demonstrated significant improved performance above ANSI/IEEE standards. See T able 8 .3-3 and T able 8 .3-4 for results.38381501506006004050.46581.92531.5386005538384050.46581.91111a When RBA expulsion fuses are used, and two ratings appear, the lower rating applies when thelower-rated switch (15 kV, 40 kA fault close, 25 kA short-time current) versus the higher rating that applies when the higher-rated switch (15 kV, 61 kA fault close, 38 kA short-time) is used.Motor Operated MVSApplicationEaton’s MVS Pow-R-Drive E motor operator makes possible the safety and convenience inherent in remote switch operation.Motor Operated MVS Switch DescriptionA MVS Pow-R-Drive motor operatedswitch is a standard, manually operatedswitch in combination with a heavy-dutyelectric motor-driven linear actuator thatcharges the spring. T he linear actuator islocated in a separate isolated low-voltagecompartment. During electrical operation,it smoothly and quietly extends orretracts the proper distance to cause theswitch mechanism to operate.Standard motor operators are mounted inthe switch enclosure. T his eliminates theneed for a separate motor compartmentconserving floor space.Manual Operation OverrideManual OperationTo operate manually, loosen the holdingscrew that keeps the pin connecting thelinear actuator to the mechanism, andremove the pin. Remove the clevis pinon the support of the bottom of the linearactuator. Unplug the cord from thedisconnect i ng terminal block as theactuator is removed and set the actuatoraside. T he switch can now be operatedmanually with the removable handle.Lock Open Key InterlockA keyed lock is standard to lock the switchin the open position only.This lock not only locks the switch in theopen position, but also breaks theelectrical motor contacts integral to themotor control circuit and permits the keyto be removed. With the key, the operatorcan then open the lock on the switch door.This scheme gives positive assurance thatthe switch is open and cannot be closedwith the door open.MeteringElectronic Metering and Communications ApparatusMVS switchgear assemblies can be equipped with Eaton’s family of Power Xpert T and IQ digital meters to monitor a power circuit’s electrical quantities within the capabilities of each device. Eaton’s power management products provide hardware and softwaresolu t ions that allow customers to interface with their switchgear at varying levels of sophistication. Power Xpert and IQ Meters monitor common electrical parameters and communicate the data via standard industry protocols and optional web interfaces. Power Xpert Gateways consolidate devices into a single web browser interface and provide Ethernet connectivity. Eaton’s Foreseer web-based software system can display, analyze and store data from multiple devices across the facility to enable management of the customer’s power system.Electronic Metering Outdoor Enclosures Weatherproofing complying with the requirements of IEEE standard C37.20.3 is available for MVS switch g ear assemblies. The weatherproofing consists of sloped roof panels that are joined together with caps. Doors and rear covers are fully gasketed. Externally accessible louvered filtered covers, top and bottom, front and rear, are provided for ventilation. At least one 250 watt heater is provided in each vertical section. Power for the heaters may be supplied from an external source, or an optional integral control power transformer may be specified to provide power for the heaters.Outdoor EnclosurePower Xpert MeterPXM 4000/6000/8000IQ 130/140/150/250/260Automatic Transfer ControlT wo-Switch Automatic T ransferApplicationEaton’s MVS switchgear with an automatic transfer control system is an integrated assembly of motor operated MVS switches, sensing devices and control components. Available in 38 kV class.It is typically applied where the continuity of service for critical loads from two power sources in either a main/main or a main/ tie/main configuration is desired.MVS switchgear with an automatic transfer control system can meet most automatic throwover requirements as it has a wide variety of operational sequences embodied in one standard automatic transfer control system. Please note that the duty cycle of load interrupter switches is limited by ANSI Standard C37 .22 . Refer to T able 8 .3-3for maximum number of switching operations allowed . If the number of switching operations is expected to exceed the maximum allowed, then load interrupter switches should not be used . Use circuit breakers (refer to T ype MSB, MEB, MEF or V CP-W switchgear designs) . Also note that the operating times of Eaton’s motor operated load interrupter switches are much longer compared to circuit breakers, therefore, the switches are not suitable for closed-transition transfer applications . Use circuit breakers if closed-transition transfer is required . T ypical T wo-Switch AutomaticT ransfer Using ATC ControllerEaton’s ATC-900 controller continu o uslymonitors all three phases on both sourcesfor correct voltages. Should the voltageof the normal source be lost while thevoltage of the alternate source remainsnormal, the voltage sensing function inthe ATC controller will change statestarting the time delay function. If thevoltage of the normal source is notrestored by the end of the time delayinterval, the normal switch will open andthe alternate source switch will close,restoring power to the load.ATC ControllerEaton’s ATC controller is equipped todisplay history information via the frontpanel. ATC-900 controller stores 320 timestamped events. Oscillographic data forlast 10 events can be downloaded via theUSB port or displayed in the controller’sdisplay window. T he controller allowscommunications via RS-232 or Modbusthrough RS-485 port, Ethernet or viaUSB interface.ATC ControllerStandard Features■■Voltage sensing on both sources isprovided by the ATC controller■■Lights to indicate status of switches,sources, etc.■■Interlocking to prevent paralleling ofsources via software■■Control power for the automatictransfer control system is derived fromthe sensing voltage transformers■■Manual override operation■■Open transition on return to normal■■Programmable time delays on bothsources, “OFF DELA Y” and “ON DELA Y”■■Four programmable digital inputsand outputs■■Single-source responsibility; all basiccomponents are manufac t ured by Eaton■■Key interlocking of operating systemand doors where required to provideoperator safetyOptional Features■■Lockout on phase and/or groundovercurrents and/or internal bus faults■■Blown fuse overcurrent lockout■■Load current, power and PF meteringwith optional dcT module■■24 Vdc control power input■■Up to four additional I/O modules, eachwith four programmable digital inputsand digital outputsSurge ProtectionIEEE standard C62.11 for Metal Oxide Surge Arresters lists the maximum rated ambient temperature as 40 °C. T he ambient temperature inside an Eaton MVS switchgear vertical section may exceed this temperature, especially in outdoor applications where solar radiation may produce a significant contribution to the temperature. T able 8 .3-6 lists the recommended minimum duty cycle voltage rating for various system grounding methods. Surge arrester rating is based upon the ambient air temperature in the switchgear vertical section not exceeding 55 °C.33.0034.50 38.0027303022.0024.4024.403030—24.4024.40———————27303022.0024.4024.4036363629.0029.0029.004548—36.5039.00—Note: MCOV = Maximum Continuous Operating Voltage.System OptionsPartial Discharge Sensing and Monitoring for SwitchgearPartial Discharge in SwitchgearPartial discharge (PD) is a common name for various forms of electrical discharges such as corona, surface tracking, and discharges internal to the insulation. It partially bridges the insulation between the conductors. T hese high frequency discharges are essentially small arcs occurring in or on the surface of the insulation system when voltage stress exceeds a critical value. With time, airborne particles, contaminants and humidity lead to conditions that result in partial discharges. Partial discharges start at a low level and increase as the insulation becomes deteriorated. Examples of partial discharge inswitchgear are surface tracking across bus insulation, or discharges in the air gap between the bus and a support (such as where a bus passes through an insulating window between the sections of the switchgear). If partial discharge activity is not detected and corrected, it can develop into a full-scale insulation failure followed by an electrical fault. Most switchgear flashover and bus failures are a result of insulation degradation caused by various forms of partial discharges.Sensing and MonitoringEaton’s T ype MVS metal-enclosedswitchgear (2.4–27 kV) is corona-free by design. By making switchgear assemblies corona-free, Eaton has made its standard switchgear more reliable. However, as indicated above, with time, airborne particles, contaminants and humidity lead to conditions that cause partial discharges to develop in switchgear operating at voltages 4000 V and above. Type MVS switchgear can be equipped with factory-installed partial discharge sensors and a partial discharge sensing relay for continuous monitoring under normal operation. T imely detection ofinsulation degradation through increasing partial discharges can identify potential problems so corrective action can be planned and implemented long before permanent deterioration develops. Partial discharge detection can be the foundation of an effective predictive maintenance program. T rending of partial discharge data over time allows prediction of failures, which can be corrected before catastrophic failure occurs.The PD sensing and monitoring system consists of Eaton’s InsulGard T relay and PD sensors, specifically developed for application in the switchgear to work with the relay. T here are two types of PD sensors used in the switch g ear: the first sensor is a coupling capacitor type sensor developed for use with 5 kV, 15 kV and 27 kV switchgear.The coupling capacitor sensor detects partial discharges within the switchgear cubicle and/or adjacent cubicles, and is typically installed on the load side of the feeder switches or on the main bus. T he second sensor is a small donut type radio frequency current transformer (RFCT). It is designed for installation around the ground shields of incoming or outgoing power cables. It detects partial dis c harges in power cables and monitors for external electrical noise.Typically one set of coupling capacitor sensors is used at every two cubicles. One RFCT sensor is used for each incoming and outgoing power cable circuit.Output signals from sensors (coupling capacitor and RFCT) are wired out to terminal blocks for future or field use, or connected to the InsulGard relay. One InsulGard relay can monitor up to 15 input signals, as well as temperature and humidity. T he temperature andhumidity sensors are included with each InsulGard relay system. T he relaycontinuously monitors the switchgear primary system for partial discharges and provides an alarm signal (contact closure) when high PD level is detected. Also, data analysis and diagnostics by Eaton engineers can also be provided by remote communication with the InsulGard relay.The sensors and InsulGard relay are optional in MVS switchgear .Figure 8.3-5.

Use one RFCT at each incoming/outgoing cable circuit.PD SensorsCoupling Capacitor detects partial discharges internal to switchgear compartment.RFCT detects partial discharges in customer’s cables up to 100 ft from switchgear.MVS LayoutsTypical Arrangements—38 kVThe drawings in this section represent the most common arrangements. Layouts shown are for rear-accessible equipment . Front-accessible designs are available—refer to Eaton . Many other configurations and combinations are available. T wo voltage transformers for metering and one control transformer for auxiliary power can be mounted in the structures shown. For control power above 1 kVA, additional space is required. Depth of units will vary due to cable entrance and exit requirements, the addition of lightning arresters, instrument transformers, special cable terminators, etc. Cables are shown out top and bottom for layout only. T op or bottom must be selected for incoming and for outgoing cables. Cable sizing is based on two 500 kcmil XLP or EPR insulated cables per phase using preformed slip-on cable termination devices.Note: Width for Utility Metering Structures may vary.ATC = Automatic T ransfer Controller (see Page 8 .3-9)M = Motor OperatorPLC = Programmable Logic ControllerNote: Not to be used for construction purposes unless approved.Figure 8.3-9.

If you want to break this application limitation, it is required to use two-stage compressor or cascade system. Meanwhile, the working condition of high pressure ratio brings problems to the traditional single-stage compressors during compression process, such as excessive gas leakage and high exhaust temperature etc., which leads to low efficiency and poor reliability when it is working is such harsh conditions.The compound two-stage compressor well solves above problems. Compared with the two-stage compressors or cascade system, the compund two-stage compressors occupy less space and the system is easy to control, so it's more efficiency and reliable.LT Series compound two-stage compressor’s evaporation temperature can be as low as -60~-65°C , Its full load evaporating temperature can be -25°C, LT-S-L Series compound two-stage low temperature compressor is based on the LT-S series which modified the internal structure and optimized the motor matching to increase the compressor full-load evaporation temperature to -10 °C, So that LT-S-L series can meet the requirements of industrial refrigeration、quick freezing tunnel and freezing library without pre-coolingFor above reasons, Therefore The Shanghai Hanbell Precise Machinery Co., Ltd. developed the LT series high temperature compressors. High efficiency and reliability under big pressure differential and compression ratio working condition is the main demand in designing. It is a elitist product which accumulates Shanghai Hanbell's rich technology and extensive application experience. It can be widely used in many industries such as high temperature hot water, central heating and so on.2.

As shown in Figure 3-1 below.When the spool is fully in contact with the suction side, the screw rotor is in full-load suction state, at which time the working volume of the compressor is maximized. As the spool is separated from the suction side, it moves toward the exhaust side. A bypass cavity is formed between the slider and the suction side.Its presence causes the compressed gas in this range to be bypassed directly to the low pressure, and the actual suction volume of the screw rotor is reduced.The more the slide valve moves toward the exhaust side, the smaller the actual suction volume of the compressor will be.And the system cooling capacity will also reduce The slide valve is driven by the pressure differential among the internal capacity modulation system.The lubricant comes from the external oil separator and passes through the oil filter then enters into the oil inlet port of the compressor, and at last divided to bothsides of the piston. As a result, the piston can be controlled by discharging the high pressure lubricant at one side to low pressure, letting it flow to the low pressure side so that the slide valve will move with the piston to realize the loading and unloading of the compressor.The purpose of the piston spring is to push the piston to its initial position (min. load position), so as to realize the automatic unloading start. It not only reduces the mechanical impact on the compressor's moving parts, but also reduces the electrical current during compressor start up.Stepless capacity control, solenoid valve(SV1:unloading, SV3:50%, SV5:100%) is controlled by a micro controller or a thermal switch to adjust the piston smoothly to stably control cold output. If the oil filter capillary or solenoid valve of the capacity modulation system don't work properly, it will cause the capacity modulation system to be abnormal and fail.Figure 3-1.Capacity Modulation System3.2.1 Step type capacity modulation system1） Step type control logicY: Energize the solenoid valve N: Do not energize the solenoid valveTable 3-1. Step Type Capacity Modulation Control Logic2） Step type capacity modulation graphFigure 3-2. Step Type Capacity Modulation3）Step type control logic description10% loadFigure 3-3. 10% LoadWhen starting up thecompressor, SV1(unload) &SV2 (10%) need to beenergized to make the pistonkeep at the 10% position(leftside)In this state, the highpressure oil passes throughSV1(unload) then goes to theright side of the piston. At thesame time, the oil from left side of the piston passes through SV2 (10%) then discharge to the low pressure side. By doing so, the piston can be held at the 10% load position.★ Note: 10% load is for start up only. Running the compressor at 10% load for a long time is not recommended.50% loadAt this time, the capacity adjustment solenoid valves SV1 (unload) and SV3 (50%) are active.Under 50% load, SV1(unload) &SV3 (50%) are energized.In this state, the high pressure oil passes to the left side of the piston continuously. At the same time, the oil passes through SV1 (unload) then goes to the right side of the piston.If the piston is at the left side of the 50% hole (the loading is less than 50%), the oil at the right side of the piston will pass through SV3 (50%) and discharge to the low pressure side then the piston will move to right side until the position blocks the 50% hole. Thus the compressor is loaded to 50% smoothly.Vice versa, if the piston is at the right side of the 50% hole (the loading is more than 50%), the oil in the left side of the piston will pass through SV3 (50%) and go out to the low pressure side then the piston will move to left until the position blocks the 50% hole. Thus the compressor is loaded to 50% smoothly.75% LoadUnder 75% load, SV1（unload）&SV4 (75%)are energized.The logic of 75% load issimilar to that of 50%. Thepiston can be held around75% position by 75% holeto make the compressorrun under 75% load.Figure 3-5.75% Load100%LoadUnder 100% load, SV5(100%) is energized. In this state,the high pressure oil passes to theleft side of the piston continuously.At the same time, the oil in theright side of the piston passesthrough SV5 (100%) then goes tothe low pressure side to make thepiston be held at 100% position.fig3-6.100% Load4） Step type capacity modulation and water temperature controlFigure 3-7.Step type capacity modulation and water temperature control★Note: T & T' should be adjusted by system designer’s experience and practical application.Time启动Set point + 2TSet point + TSet pointSet point – T'Storage temperaturet1 t21~3min 60~90 sec3.2.2Stepless type capacity modulation systemStepless type is suitable when the refrigeration system needs to achieve precise control of cooling capacity.1）Stepless type control logicTable 3-2. Stepless Type Capacity Modulation Control Logic 50%~100%2）Stepless type capacity modulation graphFigure 3-8.Stepless Type Capacity Modulation3）Stepless type control logic descriptionIn stepless type capacity modulation system, the oil keeps going to the left side of the piston. The oil bypass in the left side of the piston is controlled by SV3 (50%). The oil inlet in the right side of the piston is controlled by SV1 (unload) and oil bypass in the right side of the piston is controlled by SV5 (100%). These three solenoid valves are controlled by temperature controller or PLC.Through the three solenoid valves, the cooling capacity can be controlled at any position from 50%~100%, so through periodical adjustment of SV1、SV3、SV5, the energy output can controlled stably.★Note: SV2(10%) can only be used for machine start and stop. Don't run the machine at 10% load for long time once the machine is started. It shall be switched to load model directly.The stepless type capacity modulation system shall be connected to the micro controller(optional), eg. PLC etc. in order to control the system at the target working condition.LoadDuring load process, the SV5 (100%) adopts pulse activating, and the rest solenoid valve are not energized.In this kind ofsituation, the highpressure oil goes into theleft side of the pistoncontinuously and the oilin the right side of thepiston bypasses throughSV5 (100%) to the lowpressure side.The piston willcontinue to move to theright side and thecompressor completeload process.Figure 3-9. LoadUnloadDuring unload process,the SV2(50%) stays active,and SV1 (unload) adopts pulseactivating, and the restsolenoid valve are notenergized.The high pressure oilcontinues to go to the left sideof the piston and goes into theright side of the piston passingthrough SV1(unload).Through SV3(50%), it Figure 3-10. Unload bypasses to the low pressure side, so that the piston continues to move to the left side, and the compressor will load to 50% piston.Keep load stateFigure 3-11. Keep Load StateDuring this process, all S/V are not energized. The high pressure oil coming continues to go to the left side of the piston. The left side oil inlet of the piston SV1(unload) and SV5(100%) are closed to keep the oil amount in the right side of the piston. The piston will not be able to move and stay at its original position, so that the compressor capacity will not change as well.Stepless type capacity modulation and water temperature controlBelow picture shows the load control of single compressor in the application of stepless type capacity modulation.Figure 3-12. Stepless Type Capacity Modulation★Note ：X ′Upper Limit ；X 〞Lower Limit ；X Set Point ；H Control Range ；Y Actual valve❆ Description:● The actual water temperature exceeds the upper limit between A & B. Itmeans the compressor ought to unload until the actual value is within the control range.● The real value is smaller than the bottom line between C & D. It means therequired cooling capacity is decreasing and the compressor needs to be unloaded until the real value returns to the control range.Figure 3-13.

Hanbell designs for LT compressor the function of unloading startup. To ensure compressor loads steadily, please follow Figure 3-16 to load step by step during the whole loading process.When compressor is about to shut down, it is also required to unload to ensure that the slide valve is at lowest loading position during next startup and compressor could have an unloading startup. Thus Hanbell requires no matter what load condition of the compressor is, it should be unloaded step by step till minimum load before stop according to below Figure 3-16.Figure 3-16. Compressor Startup and Stop ProcessCaution：1）A fter startup, keep the minimum load for 10 seconds. Before shut down, keep the minimum load for 30 seconds(Time can be set to 10~60seconds).2）A fter startup, when the pressure difference between high pressure and middle pressure is less than 3.5bar, the compressor shall be run at 10% load at low pressure stage. Don't load and open ECO.3）t=30 seconds(Time can be set to 30~60seconds).4）A fter the compressor shut down, the SV1 (unload) & SV2(10%) need to be still energized for 3 minutes, so as to ensure the compressor can still at min load position at next startup.5）H anbell strongly recommends that the compressor start-up and shutdown control logic shall refer to above graph. For detail informationplease refer to the regulations written in LT-S Control Requirements.4.LubricantTable 4-1. Lubricant SpecificationCaution:1）P lease refer to the table above to select the suitable lubricant and refrigerant and its operation range need to be taken into consideration as well.2）H anbell strongly recommends do not use the lubricant which isn’t certified by Hanbell since it may damage the compressor seriously.3）T his specification table is for LT series compressors only.4）T he oil temperature at the point when the compressor starts is suggested to be 5K higher than the corresponding saturation temperature of the oil separator in order to avoid too much oil containing in the refrigerant which may affect the lubricant. 5）A fter compressor stops, please turn on the oil heater of the external oil separator.If the compressor shuts down for a long time, please turn off the oil heater. Please heat the lubricant for more than 2 hours before next start up.1）B e sure to make the system clean and no welding spatter and other impurities before lubricant filling2）I n order to ensure that the system is dry enough, it should be dehumidified before filling. It is advisable to fill the system with dry nitrogen first and then vacuum the system. The vacuum time should be as long as possible. It is strongly recommended to repeat the above steps several times to minimize the water contained in the system.Caution1）D o not use the lubricant which is not approved by Hanbell, otherwise it may causeserious damage to the compressor2）D o not mix different brands of lubricants, otherwise they may cause serious damage to the compressor. Pay attention to it when replacing lubricating oil for the system.4.2The Replacement of Lubricant4.3.1Oil Change Schedule1）C heck lubricant every 10,000 hours after continuous running. For the first operation of the compressor, it is recommended to change the oil and clean the external oil filter after running 2,000 hours. Check the system whether clean or not and then change oil every 20,000 hours or after 4 years continuous running if the system operates in good condition.2）T he oil will deteriorate if the compressor runs at high discharging temperature (above 95℃) in the long term. Please avoid this situation, but if it’s necessary to run in this condition, please shorten the intervals of oil changing.4.3.2Pre-cautions for changing oil1）I t is recommended to check the quality of oil periodically in order to maintain the lubrication performance.2）T he lubricant absorbs moisture in the air. Avoid to expose it to the air for a long timeIf the compressor motor is burned, the acid and harmful substances and burned debris will be brought into the system. Therefore, the oil filters and lubricants must be replaced repeatedly. It is suggested to replace the lubricating oil again after 72 hours of operation until the quality of the lubricating oil in the system returns to standard valve.3）T he foreign body in the oil will block the oil line, so it is necessary to install an oil filter in the external oil line. Also, the pressure differential sensor need to be installed before and after the oil filter. If the pressure differential valve between these two sensors reaches 1.5 bar, the oil filter need to be changed.4）T he acidity of oil will directly affect the life of the motor, and it is recommended to change the oil when PH≤6. (Please also change the filter drier at the same time to make sure the system is dry.）5）I t is important to replace the oil, especially when the motor is burnt because the acidity remains in the system. By replacing the oil can help check the status of thesystem. Check the acidity of the lubricant, and re-change the oil after the system runs for 72 hours until the acidity of the lubricant reaches the standard valve.6）I n case of motor burned out, please not only change the compressor, but also change the oil and check the condition of the oil periodically. If the acidity excesses the standard, please change it immediately and always be aware of the cleanliness and moisture contained in the system.5. System Application★Note ：Please consult Hanbell for parallel application and heat pump application.5.1 Piping Design5.1.1 Suction and Discharge Piping Layout1）Material and structure of suction and discharge pipeThe vibration of the compressor is small in normal operation, so it is not necessary to use flexible joints for suction and discharge tubes, but the pipes need to have enough flexible length to ensure the suction and discharge pipes won't cause any stress to the compressor. It is recommended to use copper tube for the suction and discharge piping in order to decrease the piping vibration when the compressor is in operation.2）The dimensions of suction and discharge piping:It is suggested to design the dimension of suction and discharge piping according to Hanbell recommendation (refer to 10.2.2).3）Piping for parallel systemTo improve the system operation efficiency, it’s necessary to reduce the gas -flow resistance and consider the oil return of suction piping. The recommended piping of suction and discharge side for parallel system is shown below:Be aware of the area of the main pipe should not be less than the area of the other pipes to make sure the pressure drops could be controlled in reasonable range. ❆ Piping at discharge side❆ x x xFigure 5-2 Suction Piping for Parallel SystemDetail Drawing 2 4) Suction filterThis model of compressor has a built-in suction filter, but it is only used as a final protection. It should not be used as an suction filter that needs to be cleaned regularly.So It is necessary to install a suction filter (25μm) which is easy to remove and clean it regularly.When the system is first used, it may need to be cleaned up frequently. If the pressure drop is bigger than 0.5 bar, the filter element should be replaced or cleaned until the system is clean. When the filter is disassembled, if the filter is found to be damaged, it needs to be replaced in time, and the impurities in the pipeline should be cleaned up. Ensure that the filter is oriented correctly during installation and it is recommended to add a shut-off valve at the inlet and outlet for easy maintenance.Hanbell The recommended suction filter design is shown in Figure 5-3 below.Figure 5-3.suction filterx xx Detail Drawing 2★Note：External suction filter should be used for cryogenic refrigeration systems。

SMT制程氮气保护设备--PSA制氮机

SMT製程氮氣保護設備--PSA製氮機製氮設備是根據變壓吸附的技術（PSA），利用高品質的碳分子篩為吸附劑直接從壓縮空氣中分離氧氣提取氮氣的。

經過淨化乾燥的壓縮空氣，在壓力作用下，利用氧在碳分子篩微孔中擴散吸附速率遠大於氮在碳分子篩微孔中的擴散吸附速率這一特徵，在吸附未達到平衡時，氮在氣相中被富集起來，形成成品氮氣。

然後經減壓至常壓，吸附劑脫附所吸附的氧氣等雜質組成，實現再生。

在系統中設置兩個吸附塔，一塔吸附產氮，另一塔脫附再生，通過PLC程式控制器控制氣動閥的啟閉，使兩塔交替循環工作，實現連續生產高品質氮氣。

PSA製氮設備提取氮氣可達到的技術指標氮氣流量：氮氣純度：98%—99.9995%出口壓力：0.8Mpa以下可調露點：-45℃工作原理無鉛製程中加氮氣的優點:加氮氣可以增加無鉛焊接的上錫效果,可以增加上錫的光澤度.加氮氣的優點:1.增進製程的空間2.防止氧化及增進零件吃錫度3.增進外觀美化(無鉛製程其銲點光澤較為不明顯)4.減少因長時間高溫所產生的退色情形第一部分無鉛焊接與氮氣為什麼要導入無鉛工藝鉛是一種有毒的重金屬，人體過量吸收鉛會引起中毒，攝入低量的鉛則可能對人的智力、神經系統和生殖系統造成影響，全球電子裝聯行業每年要消耗大約60000噸左右的焊料，而且還在逐年增加，由此形成的含鉛盤的工業渣滓嚴重污染環境，因此減少鉛的使用已成為全世界關注的焦點，歐洲、日本許多大公司正在大力加速無鉛替代合金的開發，並已計劃在2002年開始在電子產品裝配中逐步減少鉛的使用。

（傳統的焊料成份63Sn/37Pb，在目前的電子裝聯行業，鉛被廣泛使用）歐盟組織2006年開始逐步導入無鉛工藝（醫療電子行業推?到2008年），7月之前全面導入無鉛工藝。

電子整機行業的無鉛化技術發展是國際信息產業工業發展的必然趨勢，我國信息產業部要求在2006年7月1日前，全國實現電子信息產品的無鉛化。

導入無鉛工藝為什麼要用氮氣無鉛化對再流焊設備提出了許多新的要求，主要包括：更高的加熱能力、空載和負載狀態下的穩定性、適合高溫工作的材料、良好的熱絕緣、優良的均溫性，氮氣防漏能力、溫度曲線的靈活性、更強的冷卻能力等。
