谷轮涡旋压缩机故障现象
谷轮涡旋压缩机故障现象谷轮涡旋压缩机主要故障主要有以下四种：①浮动密封圈损坏，高低压串气。
由涡旋压缩机的结构特点可知，为了在涡旋定子上部提供适当的气体压力，在涡旋定子上的适当的中间压缩处开了一个中间压力通道，以提供中间压力。
在中间压力腔上部设有浮动密封装置，因此涡旋顶部受排气压力与中间压力作用。
除了平衡涡旋内部压缩气体压力以外，还提供了顶端和底槽间的密封力，该密封力靠浮动密封圈来实现。
该密封圈由一种类似于橡胶或塑料的非金属材料制成。
故障现象一般表现为压缩机电机完好，并且能够通电运行，但机组的排气压力不升高，吸气压力也不降低，吸气与排气几乎没有压差，排气管不热，吸气管也不凉。
压缩机电流与额定值差别很大，事实上压缩机在空转。
②涡旋盘损坏。
涡旋盘损坏除有上述浮动密封圈损坏的特征外，还能听到压缩机内部明显的金属撞击声，这是涡旋盘被击碎后的金属碎片相互撞击或与压缩机壳体撞击的声音。
③电机烧毁。
当接通电源时，熔断器熔断或短路器跳断，压缩机无法启动。
④电机抱轴，轴承损坏。
压缩机电源接通时，听到机壳内电动机有嗡嗡的声音，但不运转，并且电流上升很快，几秒钟后，压缩机内部过载保护或外部热继电器保护动作，切断电源。
有时保护器来不及动作，很快达到堵转电流，可能直接导致电机烧毁。
2故障原因分析及防治措施2.1故障压缩机解剖后发现，密封圈发生了局部的融化或是断裂。
其原因是：由于制冷剂泄漏等原因，吸气压力降低(但是即使装了低压保护装置，也可能还没有达到保护设定值，而低压保护并没有切断)，吸气过热度增大，致使排气温度迅速升高，这时，如果未装排气温度保护器，或是安装不当，会使系统存在严重的过热现象。
避免密封圈发生热损坏最有效的办法是正确安装排气温度保护器。
排气温度保护器的温度设定一般为125一130℃；排气温度保护器的感温包一般安装在压缩机排气管上，距离排气口不超过150 mm，感温包与排气管固定要牢固，并且需要严格保温；排气温度保护器的接线可以和压缩机的其他保护措施(如高压保护或低压保护)串联起来，共同形成对压缩机的保护。

Typical model numbers include ZW30KA-PFS and ZW61KSE-TFP. This bulletin addresses the specifics of water heating in the early part and deals with the common characteristics and general application guidelines for Copeland Scroll compressors in the later sections. Operating principles of the scroll compressor are described in Figure 15 at the end of this bulletin.As the drive for energy efficiency intensifies, water heating by fossil-fueled boilers and electric elements is being displaced by vapour compression heat pumps. Emerson Climate Technologies has developed two lines of special water heater compressors to meet the requirements of this demanding application. ZW**KA compressors are designed for lighter duty applications where the ambient temperature does not fall below 0°C and where lower water temperatures can be accepted as the ambient temperature falls. ZW**KS compressors are equipped with a vapour injection cycle which allows reliable operation in cold climates with significantly enhanced heating capacity, higher efficiency, and minimal requirement to reduce water outlet temperatures. Figure 1gives a brief product overview.Water heating is characterized by long operating hours at both high load and high compression ratios. Demand for hot water is at its highest when ambients are low and when conventional heat pump capacity falls off. On the positive side, the system refrigerant charge is usually small, so the risk to the compressor from dilution and flooded starts will usually be lower than in split type air-to-air heat pumps.Water heaters must operate in a wide range of ambient temperatures, and many systems will require some method of defrost. Some systems such as Direct Heating, Top Down Heating or Single Pass Heating operate at a constant water outlet temperature with variable water flow. Others such as Recirculation Heating, Cyclic Heating or Multipass Heating use constant water flow with the water outlet and inlet temperatures both rising slowly as the storage tank heats up. Both system types need to cope with reheating a tank where the hot water has been partially used, and reheating to the setpoint temperature is required. More complex systems deliver water at relatively low temperatures for under-floor heating circuits and are switched over to sanitary water heating a few times per day to provide higher temperature water for sanitary use. In addition, some countries have specific water temperature requirements for legionella control.ZW**KA ApplicationThe application envelopes for ZW**KA compressors are shown in Figures 2 - 4.Appropriate system hardware and control logic must be employed to ensure that the compressor is always operating within the envelope. Small short-term excursions outside the envelope are acceptable at the time of defrost when the load on the compressor is low. Operation with suction superheat of 5 -10K is generally acceptable except at an evaporating tem-perature above 100C when a minimum superheat of 10K is required.ZW**KS ApplicationThe ZW**KS* vapour-injected scroll compressors differ from ZW**KA models in many important details:• Addition of vapour injection• Significantly different application envelopes• Some differences in locked rotor amps (LRA), maximum continuous current (MCC), andmaximum operating current (MOC) – seenameplatesThe application envelopes for ZW**KS compressors are shown in Figures 5 and 6.Vapour Injection – Theory of Operation Operation with vapour injection increases the capacity of the outdoor coil and in turn the capacity and efficiency of the system – especially in low ambient temperatures. A typical schematic is shown in Figure 7. A heat exchanger is added to the liquid line and is used to cool the liquid being delivered to the heating expansion device. Part of the liquid refrigerant flow is flashed through an expansion valve on the evaporator side of the heat exchanger at an intermediate pressure and used to subcool the main flow of liquid to the main expansion device. Vapour from the liquid evaporating at intermediate pressure is fed to the vapour injection port on the ZW**KS compressor. This refrigerant is injected into the mid-compression cycle of the scroll compressor and compressed to discharge pressure. Heating capacity is increased, because low temperature liquid with lower specific enthalpy supplied to the outdoor coil increases the amount of heat that can be absorbed from the ambient air. Increased heat absorbed from the ambient increases the system condensing temperature and in turn the compressor power input. The increase in power inputalso contributes to the improvement in the overall heating capacity.Vapour Injection can be turned on and off by the addition of an optional solenoid valve on the vapour injection line on systems using a thermostatic expansion valve. Alternatively, an electronic expansion valve can be used to turn vapour injection on and off and to control the vapour injection superheat. A capillary tube is not suitable for controlling vapour injection.The major advantage of the electronic expansion valve is that it can be used to optimise the performance of the system and at the same time control the discharge temperature by injecting “wet vapour” at extreme operating conditions.The configurations and schematics shown are for reference only and are not applicable to every system. Please consult with your Emerson Application Engineer.Heat Exchanger and Expansion Device Sizing Various heat exchanger designs have been used successfully as subcoolers. In general they should be sized so that the liquid outlet temperature is less than 5K above the saturated injection temperature at the customer low temperature rating point. At very high ambient temperatures, it will normally be beneficial to turn vapour injection off to limit the load on the compressor motor. Application Engineering Bulletin AE4-1327 and Emerson Climate Technologies Product Selection Software can be used to help size the subcooling heat exchanger and thermal expansion valves, but selection and proper operation must be checked during development testing. Plate type subcoolers must be installed vertically with the injection expansion device connected at the bottom through a straight tube at least 150mm long to ensure good liquid distribution. See the schematic in Figure 8. Flash Tank ApplicationA possible flash tank configuration is shown in Figure9. This particular configuration is arranged to have flow through the flash tank and expansion devices in heating, and it bypasses the tank in defrost mode. The flash tank system works by taking liquid from the condenser and metering it into a vessel through a high-to-medium pressure expansion device. Part of the liquid boils off and is directed to the compressor vapour injection port. This refrigerant is injected into the mid-compression cycle of the scroll compressor and compressed to discharge pressure. The remaining liquid is cooled, exits from the bottom of the tank at intermediate pressure, and flows to the medium-to-low pressure expansion device which feeds the outdoor coil. Low temperature liquid with lower specific enthalpy increases the capacity of the evaporator without increasing mass flow and system pressure drops.Recommended tank sizing for single compressor application in this size range is a minimum of 200 mm high by 75 mm in diameter with 3/8 in. (9.5mm) tubing connections, although it is possible to use a larger tank to combine the liquid/vapour separation and receiver functions in one vessel. A sight tube (liquid level gauge) should be added to the tank for observation of liquid levels during lab testing. See schematic diagram Figure 10 for clarification.It is important to maintain a visible liquid refrigerant level in the tank under all operating conditions. Ideally the liquid level should be maintained in the 1/3 to 2/3 full range.Under no circumstances should the level drop to empty or rise to a full tank. As the tank level rises, liquid droplets tend to be swept into the vapour line leading to “wet” vapour injection. Although this can be useful for cooling a hot compressor, the liquid quantity cannot be easily controlled. Compressor damage is possible if the tank overflows. If liquid injection is required for any reason, it can be arranged as shown in Figures 7 and 9.Since liquid leaves the tank in a saturated state, any pressure drop or temperature rise in the line to the medium-to-low pressure expansion device will lead to bubble formation. Design or selection of the medium-to-low pressure expansion device requires careful attention due to the possible presence of bubbles at the inlet and the low pressure difference available to drive the liquid into the evaporator. An electronic expansion valve is the preferred choice. Intermediate Pressure and Vapour Injection SuperheatPressure in the flash tank cannot be set and is a complex function of the compressor inlet condition and liquid condition at the inlet of the high-to-medium pressure expansion device. However, liquid level can be adjusted, which in turn will vary the amount of liquid subcooling in the condenser (water to refrigerant heat exchanger) and vary the injection pressure. Systems with low condenser subcooling will derive the biggest gains by the addition of vapour injection. Systems operating with high pressure ratios will show the largest gains when vapour injection is applied. Such systems will have higher vapour pressure and higher injectionmass flow. Intermediate pressures in flash tank and heat exchanger systems should be very similar unless the subcooling heat exchanger is undersized and there is a large temperature difference between the evaporator and the liquid sides. Vapour exiting a flash tank will be saturated and may pick up 1 - 2K superheat in the vapour line to the compressor. Vapour injection superheat cannot be adjusted on flash tank systems. Heat exchanger systems will be at their most efficient when the vapour injection superheat is maintained at approximately 5K.APPLICATION CONSIDERATIONSHigh Pressure Cut OutIf a high pressure control is used with these compressors, the recommended maximum cut out settings are listed in Figure 1. The high pressure control should have a manual reset feature for the highest level of system protection. It is not recommended to use the compressor to test the high pressure switch function during the assembly line test.Although R-407C runs with higher discharge pressure than R-22, a common setting can be used. The cutout settings for R-134a are much lower, and the switches must be selected or adjusted accordingly.Low Pressure Cut OutA low pressure cut out is an effective protection against loss of charge or partial blockage in the system. The cut out should not be set more than 3 - 5K equivalent suction pressure below the lowest operating point in the application envelope. Nuisance trips during defrost can be avoided by ignoring the switch until defrost is finished or by locating it in the line between the evaporator outlet and the reversing valve. This line will be at discharge pressure during defrost. Recommended settings are given in Figure 1. Discharge Temperature ProtectionAlthough ZW compressors have an internal bi-metal Therm-O-Disc®(TOD) on the muffler plate, external discharge temperature protection is recommended for a higher level of protection and to enable monitoring and control of vapour injection on ZW**KS* models. The protection system should shut down the compressor when the discharge line temperature reaches 125°C. In low ambient operation, the temperature difference between the scroll center and the discharge line is significantly increased, so protection at a lower discharge temperature, e.g. 120°C when the ambient is below 0°C, will enhance system safety. For the highest level of system protection, the discharge temperature control should have a manual reset feature. The discharge sensor needs to be well insulated to ensure that the line temperature is accurately read. The insulation material must not deteriorate over the expected life of the unit.Discharge Temperature ControlSome systems use an electronic expansion valve to control the vapour injection superheat and a thermistor to monitor the discharge temperature. This combination allows the system designer to inject a small quantity of liquid to keep the discharge temperature within safe limits and avoid an unnecessary trip. Liquid injection should begin at approximately 115°C and should be discontinued when the temperature falls to 105°C. Correct functioning of this system should be verified during system development. It is far preferable to use liquid injection into the vapour injection port to keep the compressor cool rather than inject liquid into the compressor suction which runs the risk of diluting the oil and washing the oil from the moving parts. If some operation mode requires liquid injection but without the added capacity associated with “wet” vapour injection, a liquid injection bypass circuit can be arranged as shown in Figures 7 and 9.Caution: Although the discharge and oil temperature are within acceptable limits, the suction and discharge pressures cannot be ignored and must also fall within the approved application envelope.Discharge MufflersDischarge mufflers are not normally required in water heaters since the refrigerant does not circulate within the occupied space.Oil Dilution and Compressor CoolingThe oil temperature diagram shown in Figure 11is commonly used to make a judgment about acceptable levels of floodback in heat pump operation. Systems operating with oil temperatures near the lower limit line are never at their most efficient. Low ambient heating capacity and efficiency will both be higher if floodback is eliminated and the system runs with 1 - 5K suction superheat. Discharge temperature can be controlled by vapour injection, “wet” vapour injection, or even liquid injection if necessary. In this situation, the oil temperature will rise well into the safe zone, and the compressor will not be at risk of failure from diluted oil. The oil circulation rate will also be reduced as crankcase foaming disappears. Special care needs to be taken at the end of defrost to ensure that the compressor oil is not unacceptably diluted. The system will resume heating very quickly and bearing loads willincrease accordingly, so proper lubrication must be ensured.Electrical ConsiderationsMotor configuration and protection are similar to those of standard Copeland Scroll compressors. In some cases, a larger motor is required in the ZW**KS* models to handle the load imposed by operating with vapour injection. Wiring and fuse sizes should be reviewed accordingly.Brazing the Vapour Injection LineThe vapour injection connection is made from copper coated steel, and the techniques used for brazing the suction and discharge fittings apply to this fitting also. Low Ambient Cut-OutA low ambient cut-out is not required to limit heat pump operation with ZW**KS compressors. Water heaters using ZW**KA compressors must not be allowed to run in low ambients since this configuration would run outside of the approved operating envelope causing overheating or excessive wear. A low ambient cut-out should be set at 0°C for ZW**KA modelsIn common with many Copeland Scroll compressors, ZW models include the features described below: Internal Pressure Relief (IPR) ValveAll ZW compressors contain an internal pressure relief valve that is located between the high side and the low side of the compressor. It is designed to open when the discharge-to-suction differential pressure exceeds 26 - 32 bar. When the valve opens, hot discharge gas is routed back into the area of the motor protector to cause a trip.Internal Temperature ProtectionThe Therm-O-Disc® or TOD is a temperature-sensitive snap disc device located on the muffler plate between the high and low pressure sides of the compressor. It is designed to open and route excessively hot discharge gas back to the motor protector. During a situation such as loss of charge, the compressor will be protected for some time while it trips the protector. However, as refrigerant leaks out, the mass flow and the amperage draw are reduced and the scrolls will start to overheat.A low pressure control is recommended for loss of charge protection in heat pumps for the highest level of system protection. A cut out setting no lower than 2.5 bar for ZW**KA* models and 0.5 bar for ZW**KS* models is recommended. The low pressure cut-out, if installed in the suction line to the compressor, can provide additional protection against an expansion device failed in the closed position, a closed liquid line or suction line service valve, or a blocked liquid line screen, filter, orifice, or TXV. All of these can starve the compressor for refrigerant and result in compressor failure. The low pressure cut-out should have a manual reset feature for the highest level of system protection. If a compressor is allowed to cycle after a fault is detected, there is a high probability that the compressor will be damaged and the system contaminated with debris from the failed compressor and decomposed oil.If current monitoring to the compressor is available, the system controller can take advantage of the compressor TOD and internal protector operation. The controller can lock out the compressor if current draw is not coincident with the contactor energizing, implying that the compressor has shut off on its internal protector. This will prevent unnecessary compressor cycling on a fault condition until corrective action can be taken.Quiet Shut downAll scrolls in this size range have a fast acting valve in the center of the fixed scroll which provides a very quiet shutdown solution. Pressure will equalize internally very rapidly and a time delay is not required for any of the ZW compressors to restart. Also refer to the section on “Brief Power Interruption”. Discharge Check ValveA low mass, disc-type check valve in the discharge fitting of the compressor prevents the high side, high pressure discharge gas from flowing rapidly back through the compressor. This check valve was not designed to be used with recycling pump down because it is not entirely leak-proof.Motor ProtectorConventional internal line break motor protection is provided. The protector opens the common connection of a single-phase motor and the center of the Y connection on three-phase motors. The three-phase protector provides primary single-phase protection. Both types of protectors react to current and motor winding temperature.AccumulatorsThe use of accumulators is very dependent on the application. The scroll’s inherent ability to handle liquid refrigerant during occasional operating flood back situations often makes the use of an accumulator unnecessary in many designs. If flood back is excessive, it can dilute the oil to such an extent thatbearings are inadequately lubricated, and wear will occur. In such a case, an accumulator must be used to reduce flood back to a safe level that the compressor can handle.In water heaters, floodback is likely to occur when the outdoor coil frosts. The defrost test must be done at an outdoor ambient temperature of around 0°C in a high humidity environment. Liquid floodback must be monitored during reversing valve operation, especially when coming out of defrost. Excessive floodback occurs when the sump temperature drops below the safe operation line shown in Figure 11 for more than 10 seconds.If an accumulator is required, the oil return orifice should be 1 - 1.5mm in diameter depending on compressor size and compressor flood back results. Final oil return hole size should be determined through testing. ScreensScreens with a mesh size finer than 30 x 30 (0.6mm openings) should not be used anywhere in the system with these compressors. Field experience has shown that finer mesh screens used to protect thermal expansion valves, capillary tubes, or accumulators can become temporarily or permanently plugged with normal system debris and block the flow of either oil or refrigerant to the compressor. Such blockage can result in compressor failure.Crankcase Heater - Single PhaseCrankcase heaters are not required on single phase compressors when the system charge is not over 120% of the limit shown in Figure 1. A crankcase heater is required for systems containing more than 120% of the compressor refrigerant charge limit listed in Figure 1. This includes long line length systems where the extra charge will increase the standard factory charge above the 120% limit.Experience has shown that compressors may fill with liquid refrigerant under certain circumstances and system configurations, notably after longer off cycles when the compressor has cooled. This may cause excessive start-up clearing noise, or the compressor may lock up and trip on the protector several times before starting. The addition of a crankcase heater will reduce customer noise and light dimming complaints since the compressor will no longer have to clear out liquid during startup. Figure 12lists the crankcase heaters recommended for the various models and voltages.Crankcase Heat – Three-PhaseA crankcase heater is required for three-phase compressors when the system charge exceeds the compressor charge limit listed in Figure 1and an accumulator cannot be piped to provide free liquid drainage during the off cycle.Pump Down CycleA pump down cycle for control of refrigerant migration is not recommended for scroll compressors of this size. If a pump down cycle is used, a separate external check valve must be added.The scroll discharge check valve is designed to stop extended reverse rotation and prevent high-pressure gas from leaking rapidly into the low side after shut off. The check valve will in some cases leak more than reciprocating compressor discharge reeds, normally used with pump down, causing the scroll compressor to cycle more frequently. Repeated short-cycling of this nature can result in a low oil situation and consequent damage to the compressor. The low-pressure control differential has to be reviewed since a relatively large volume of gas will re-expand from the high side of the compressor into the low side on shut down. Minimum Run TimeThere is no set answer to how often scroll compressors can be started and stopped in an hour, since it is highly dependent on system configuration. Other than the considerations in the section on Brief Power Interruptions, there is no minimum off time. This is because scroll compressors start unloaded, even if the system has unbalanced pressures. The most critical consideration is the minimum run time required to return oil to the compressor after startup.Since water heaters are generally of compact construction, oil return and short cycling issues are rare. Oil return should not be a problem unless the accumulator oil hole is blocked.Reversing ValvesSince Copeland Scroll compressors have very high volumetric efficiency, their displacements are lower than those of comparable capacity reciprocating compressors. As a result, Emerson recommends that the capacity rating on reversing valves be no more than 2 times the nominal capacity of the compressor with which it will be used in order to ensure proper operation of the reversing valve under all operating conditions.The reversing valve solenoid should be wired so that the valve does not reverse when the system isshut off by the operating thermostat in the heating or cooling mode. If the valve is allowed to reverse at system shutoff, suction and discharge pressures are reversed to the compressor. This results in pressures equalizing through the compressor which can cause the compressor to slowly rotate until the pressures equalize. This condition does not affect compressor durability but can cause unexpected sound after the compressor is turned off.Oil TypeThe ZW**K* compressors are originally charged with mineral oil. A standard 3GS oil may be used if the addition of oil in the field is required. See the compressor nameplate for original oil charge. A complete recharge should be ~100 ml less than the nameplate value.ZW**K*E are charged with POE oil. Copeland 3MAF or Ultra 22 CC should be used if additional oil is needed in the field. Mobil Arctic EAL22CC, Emkarate RL22, Emkarate 32CF and Emkarate 3MAF are acceptable alternatives. POE oil is highly hygroscopic, and the oil should not be exposed to the atmosphere except for the very short period required to make the brazing connections to the compressor.System Noise and VibrationCopeland Scroll compressors inherently have low sound and vibration characteristics, but the characteristics differ in some respects from those of reciprocating or rotary compressors. The scroll compressor makes both a rocking and a torsional motion, and enough flexibility must be provided to prevent vibration transmission into any lines attached to the unit. This is usually achieved by having tubing runs at least 30cm long parallel to the compressor crankshaft and close to the shell. ZW compressors are delivered with rubber grommets to reduce vibration transmission to the system baseplate.Single Phase Starting CharacteristicsStart assist devices are usually not required, even if a system utilizes non-bleed expansion valves. Due to the inherent design of the Copeland Scroll, the internal compression components always start unloaded even if system pressures are not balanced. In addition, since internal compressor pressures are always balanced at startup, low voltage starting characteristics are excellent for Copeland Scroll compressors. Starting current on any compressor may result in a significant “sag” in voltage where a poor power supply is encountered. The low starting voltage reduces the starting torque of the compressor and subsequently increases the start time. This could cause light dimming or a buzzing noise where wire is pulled through conduit. If required, a start capacitor and potential relay can be added to the electrical circuit. This will substantially reduce start time and consequently the magnitude and duration of both light dimming and conduit buzzing.PTC Start ComponentsFor less severe voltage drops or as a start boost, solid state Positive Temperature Coefficient devices rated from 10 to 25 ohms may be used to facilitate starting for any of these compressors.Electrical ConnectionThe orientation of the electrical connections on the Copeland Scroll compressors is shown in Figure 13 and is also shown on the wiring diagram on the top of the terminal box cover.Deep Vacuum OperationScrolls incorporate internal low vacuum protection and will stop pumping (unload) when the pressure ratio exceeds approximately 10:1. There is an audible increase in sound when the scrolls start unloading. This feature does not prevent overheating and destruction of the scrolls, but it does protect the power terminals from internal arcing.Copeland Scroll compressors(as with any refrigerant compressor) should never be used to evacuate a refrigeration or air conditioning system. The scroll compressor can be used to pump down refrigerant in a unit as long as the pressures remain within the operating envelope. Prolonged operation at low suction pressures will result in overheating of the scrolls and permanent damage to the scroll tips, drive bearings and internal seal. (See AE24-1105 for proper system evacuation procedures.)Shell TemperatureCertain types of system failures, such as condenser or evaporator blockage or loss of charge, may cause the top shell and discharge line to briefly but repeatedly reach temperatures above 175ºC as the compressor cycles on its internal protection devices. Care must be taken to ensure that wiring or other materials, which could be damaged by these temperatures, do not come in contact with these potentially hot areas. Suction and Discharge FittingsCopeland Scroll compressors have copper plated steel suction and discharge fittings. These fittings are far more rugged and less prone to leaks than。

have ever developed for residential air condi-tioning and heat pump applications.Copeland Scroll compres-sors have fewer moving parts and no dynamic suction or dis-charge valves.In addition, they offer very low vibration and sound levels and are very tolerant to stresses caused by liquid slugging, flooded starts, and debris commonly found in resi-dential split air conditioning and heat pump systems.•These Copeland Scrolls include a higher range of capacities and more electrical options than the earlier ZR1 models.Inaddition, there are several operating characteristics and design features which are different from the ZR1 models.•The Copeland Scroll is a new type of compressor and there are a number of application characteristics which are different from the traditional reciprocating compressor.These are fully detailed in the Application Bulletin AE4-1312.•The motor protector used in these ZR compressors is mounted internally and its proven design is the result of extensive labo-ratory research and field testing.It protects the motor from maximum operating overload, both high and low voltage, and loss of refrigerant charge.It is both current and heat sensing.The single phase protector protects both the run and start windings.The three phase protector is wired at the connection point of the motor's three legs.Therefore, the protector protects all three legs and if a problem occurs with one or more of them,the protector breaks all three phases.•The rotational speed of the compressor is:•50 Hertz 2900 RPM•No crankcase heater is required for single phase compressors.•A crankcase heater is required for three phase compressors when the system charge exceeds the compressor refrigerant charge limit shown below, and no accumulator is used, or when the charge exceeds this limit and an accumulator cannot be piped to provide free liquid drainage into the accumulator dur-ing the off cycle.•ZR22 to ZR488 pounds (3.6 Kg)••Since Copeland Scroll Compressors have very high volumetricefficiency, their displacements are lower than for comparable capacity reciprocating compressors.As a result, Copeland mends that the capacity rating on reversing valves be no more than 1.5 to 2 times the nominal capacity of the compres-sor with which it will be used in order to ensure proper opera-tion of the reversing valve under all operating conditions.•The compressor has the approval to operate as a heat pump within the operating range.Its increased bearing surfaces and improved lubrication system provide excellent reliability even when operated at the heat pump's higher compression ratios.•Low ambient cut-outs are not required to limit heat pump operation.•These Scroll Compressors have internal pressure relief valves which open at a discharge to suction differential pressure of 375 to 450 psi.•No start assist devices are required.Due to the inherent design of the Scroll, the internal compression components always start unloaded even if system pressures are not balanced.•Rated load amps is the value used for contactor and other elec-trical component selection.It is calculated by dividing the max-imum continuous current that the compressor draws under the condition of maximum load operation and the lowest operating voltage by 1.4.See Application Bulletin AE 9-1154 for a detailed explanation.•Complete 50 Hertz performance curves are available in the units as follows for all models:•CapacityBTU/Hr •Power Input Watts •CurrentAmps •EfficiencyBTUH/Watt •Copeland has compiled a book of compressor Application Bulletins.Please see the following bulletins, from the book, for more ZR compressor application information as entitled below:Mounting Parts ............................AE 4-1111Application Guidelines ....................AE

数码涡旋以顺应性为其基本原理，但可通过控制涡旋盘的分离而使其功能发挥得更加 淋漓尽致。
涡旋盘中的压 缩由一个 旋转涡 旋盘和一个固 定涡旋盘 的互动 形成。当其中 一个涡旋 盘旋转
气体被吸入 螺旋后 封锁开 放通道。
当螺旋持续旋转时，气体被压 缩成两团更小的气窝，体积逐 渐减小。
当气体到达 中心口 时，达 到释放压力。
事实上，在运行过程中，所有 6 个气体通道始终都处于 不同的压 缩状态，形成近乎持续 的吸入和

使用一个电磁阀以及排气腔与吸气口的旁通连接即可实现涡旋盘的受控分离（参见图 2）。涡卷的设计使上涡旋盘可与下涡旋盘垂直分离 1mm。上涡旋盘上部附有一个活 塞，在向上运动时将提起上涡旋盘。当电磁阀关闭时，数码涡旋和普通的涡旋式压缩 机一样工作，且经压缩的气体通过普通管道在高压下排出。而当电磁阀开启时，排气 腔与吸气口相连，由此释放出部分排气压力。这可以使控制活塞的压力减小，从而使 活塞上升，随即提起上涡旋盘。一旦涡旋盘分离后，任何通过其中的气体不再受到压 缩。

谷轮数码涡旋使用简单有效的方式来调节空调的容量，提供无与伦比的性能。为更好 地了解数码涡旋如何达到其变容量目的，我们首先需要了解谷轮涡旋的工作原理。
谷轮涡旋压缩机高温保护原理
谷轮涡旋压缩机高温保护原理谷轮涡旋压缩机高温保护原理摘要：谷轮涡旋压缩机是一种高效节能的压缩机，广泛应用于工业领域。
为了确保谷轮涡旋压缩机的安全可靠运行，需要对其进行高温保护。
本文将介绍谷轮涡旋压缩机高温保护的原理和应用。
关键词：谷轮涡旋压缩机；高温保护；原理；应用。
第一节：谷轮涡旋压缩机的工作原理谷轮涡旋压缩机是一种无油、无冷却剂的压缩机，利用谷轮涡旋技术将气体压缩。
其工作原理可以简单描述为以下几个步骤：1.首先，气体通过进气口进入压缩机的工作腔，进入后与旋涡腔内的气体进行交互。
2.旋涡腔内的叶轮开始高速旋转，通过离心力将气体压缩。
3.压缩后的气体被推入压缩腔，气体在腔体内进一步压缩。
4.最后，气体通过排气口排出压缩机，完成一个循环过程。
通过谷轮涡旋技术，可以实现高效能的气体压缩，并且由于无需冷却剂和油润滑，使得谷轮涡旋压缩机更加环保和节能。
第二节：谷轮涡旋压缩机的高温保护原理在工业应用中，谷轮涡旋压缩机会遇到高温环境，其中旋涡腔和压缩腔是最容易受到高温影响的部分。
高温环境不仅会影响谷轮涡旋压缩机的正常工作，还可能引发机器故障和事故。
为了保护谷轮涡旋压缩机，通常采用以下几种高温保护原理：1.温度传感器监测：在谷轮涡旋压缩机的旋涡腔和压缩腔内安装温度传感器，实时监测气体温度。
一旦温度超过设定的阈值，压缩机将自动停止工作，通过报警系统通知操作人员处理问题。
2.冷却系统：通过增加冷却系统的供气量和供水量，将常温气体和水蒸气注入谷轮涡旋压缩机内进行冷却，以降低温度。
这种方法可以在短时间内有效降低温度，但需要注意水量和水质的控制，以免引起其他问题。
3.风扇散热：通过在谷轮涡旋压缩机周围设置风扇，利用自然风或人工风扇进行散热。
这种方法适用于小型谷轮涡旋压缩机，可以有效降低温度，但无法承受极高的温度。
以上三种高温保护原理通常结合使用，以确保谷轮涡旋压缩机在高温环境下的安全运行。
第三节：谷轮涡旋压缩机高温保护的应用谷轮涡旋压缩机广泛应用于石油、化工、电力、冶金、纺织等工业领域。
