Use a 4 mm Allen key (not supplied) tofit the actuator to the valve body.Allow for necessary clearance for maintenancepurposes.The valve has position indication ringswhich should be pushed together beforecommissioning; after stroking they indicate theends of the stroke.ElectricalElectrical connections can be accessed byremoving the cover. Two M16 × 1.5 cable entriesare provided. Both entries are provided with arubber grommet for use with flexible cable. Notethat in order to maintain the enclosure IP rating,appropriate cable glands must be used.Wiring The actuator must be dismantled and the elements sorted into various material groups before disposal.Disposal 24 Vac only.Wiring length Recommendedsquare of the wiring0-50 m0.75 mm2> 50 m 1.5 mm2Automatic self stroking featureWhen power is first applied, the actuator willautomatically adjust to the length of the valvestroke. Subsequently, the self stroking featurecan be re-initialised by changing position of SW9.Diagnostic LEDThe red diagnostic LED is located on the pcbunder the cover. It provides indication of threeoperational states:• Actuator Healthy (Permanently ON),• Self Stroking (Flashes once per second),• Error (Flashes 3 times per second - seektechnical assistance).Data sheetActuator for modulating control AME 55 QM© Danfoss | 2016.09 | 3VD.CV.A2.02DIP switch settingThe actuator has a function selection DIP switch under the removable cover. In particular, if SW6 is set to ON, the actuator will perform as 3-point actuator.The switch provides the following functions:• SW1: U/I - Input signal type selector:If set to OFF position, voltage input is selected. If set to ON position, current input is selected.• SW2: 0/2 - Input signal range selector:If set to OFF position, the input signal is in the range from 2 V to 10 V (voltage input)or from 4 mA to 20 mA (current input). If set to ON position, the input signal is in the range from 0 V to 10 V (voltage input) or from 0 mA to 20 mA (current input).• SW3: D/I - Direct or inverse acting selector:If set to OFF position, the actuator is direct acting (stem contracts as voltage increases). If actuator is set to ON position the actuator is inverse acting (stem extracts as voltage increases).• SW4: —/Seq - Normal or sequential modeselector:If set to OFF position, the actuator is working in range 0(2)..10V or 0(4)..20mA. If set to ON position, the actuator is working in sequential range; 0(2)..5 (6)V or (0(4)..10 (12)mA) or (5(6)..10V) or (10(12)..20mA).• SW5: 0..5V/5...10V - Input signal range insequential mode:If set to OFF position, the actuator is working in sequential range 0(2)..5 (6)V or 0(4)..10 (12)mA. If set to ON position, the actuator is working in sequential range; 5(6)..10V or 10(12)..20mA.• SW6: Prop./3-pnt - Modulating or 3-point modeselector:If set to OFF position, the actuator is working normally according to control signal. If set to ON position, the actuator is working as 3-point actuator.For this operation please refer to page 2(wiring 3-point control).When DIP switch SW6 is set to ON than allfunctions from other DIP switch become inactive.• SW7: LOG/LIN - Equal percentage or linear flowthrough valve selector:If set to OFF position, the flow through valve is equal percentage. If set to ON position, the flow through valve is linear according to control signal.• SW8: 100% K VS/Reduced K VS :To be set to OFF position (no sense in combination with AB-QM).• SW9: Reset:Changing this switch position will cause the actuator to go through a self stroking cycle.Complete the mechanical and electricalinstallation and perform the necessary checks and tests:• Isolate control medium. (e.g. self stroking in a steam application without suitable mechanical isolation could cause a hazard).• Apply the power. Note that the actuator will now perform the self stroking function.• Apply the appropriate control signal and check the valve stem direction is correct for the application.• Ensure that the actuator drives the valve over its full stroke, by applying the appropriate control signal. This action will set the valve stroke length.The unit is now fully commissioned.CommissioningCommissioning / testing featureThe actuator can be driven to the fully open or closed positions (depending on valve type) by connecting SN to terminals 1 or 3.VD.CV.A2.024 | © Danfoss | DHS-SRMT/SI | 2016.09Data sheetActuator for modulating control AME 55 QMActuator - valve combinationsThe manual override is applied by rotating the 4 mm Allen key (not supplied) to the required position. Observe the direction of the rotation symbol.• Disconnect power supply• Adjust valve position using an Allen key • Set valve to closed position •Restore power supplyIf manual override has been used then X and Y signal are not correct until the actuator reaches its end position. If this is not accepted reset the actuator, or apply accessory active return signal kit.DimensionsManual override。

For a given oil flow and given pressure the displacement (size of motor) determines the speed and torque. For a given displacement (size of motor) the speed is determined by the oil flow rate and the torque is determined by the pressure differential.Gearwheel setThe operating principle of the motors is based on an internal gear design, con-sisting of a fixed external gear reaching against an internal gear through which the output torque and speed are trans-mitted. There are two forms of external gear: the OML, OMM, OMP and DH have plain teeth, whereas the OMR, DS, OMH, OMEW, OMS, OMT, OMV and TMT have teeth fitted with rollers.Distributor valveThe distributor valve is driven synchronously by the internal gear through a cardan shaft ensuring that the individual chambers of the motor are filled and emptied precisely - without losses. There are two forms of distributor valve:• Spool valveOML, OMM, OMP , OMR, DH, DS and OMH motors have a spool valve: the distributor valve has been integrated with the output shaft. The cardan shaft must therefore rotate the distrib-utor valve as well as transfer mechani-cal energy from the gear-wheel set to the output shaft.• Disc valve with valve driveOMS, OMT, OMV and TMT motors have a disc valve: The distributor valve has been separated from the output shaft and it is driven by a short cardan shaft [valve drive]. A balance plate counter -bal-ances the hydraulic forces aroundthe distributor valve.B: Spool valveD: Gearwheel setA: Output shaft D: Valve drive B: Cardan shaft E: Check valve C: Gearwheel setF: Disc valveOrbital Motors, GeneralGeneral, Orbital Motors Technical Information Orbital Motors, GeneralOperating Principle (continue)Disc valve on the output shaft•OMEW motors have a disc valve-mounted on the output shaft. Thecardan shaft rotates the disc valve andtransfers mechanical energy from thegearwheel to the output shaft. Thehydraulic forces are equalised by thebalance plate.B: Disc valve D: Gearwheel set6520L0232 • Rev BD • Nov 20127520L0232 • Rev BD • Nov 2012General, Orbital Motors Technical InformationSelection of MotorSelection of Motor TypeOML, OMM, OMP, OMPW, DH - Rollerless gear rim- Spool valve integrated with output shaft - Output shaft supported in slide bearings OMPW N- Rollerless gear rim- Spool valve integrated with output shaft - Output shaft supported in needle bearings OMR, OMH, DS- Gear rim with rollers- Spool valve integrated with output shaft - Output shaft supported in slide bearings OMRW N- Gear rim with rollers- Spool valve integrated with output shaft - Output shaft supported in needle bearings OMEW- Gear rim with rollers- Disc valve on output shaft- Output shaft supported in needle bearings OMS, OMT, OMV- Gear rim with rollers- Disc valve with separate valve drive- Output shaft supported in tapered roller bearings TMT- Gear rim with rollers- Disc valve with separate valve drive- Output shaft supported in tapered roller bearingsFeatures of main typesOML, OMM, OMP, OMPW, DHCompact design. The rollerless gear rim makes these types suitable for long operating periods at moderate pressures, or short operating periods at high pressures.OMPW NCompact motor suitable for long operating periods at moderate pressures or short oper-ating periods at high pressures. The needle bearings on the output shaft make OMPW N suitable for applications with static and dynamic radial loads.OMR, OMH, DSThe rollers in the gear rim reduce local stress, spread the tooth load over their projected area and reduce the tangential reaction forces on the inner gear reducing friction to a minimum. This gives long operating life and better efficiency even at continuous high pressures. Gearwheel sets with rollers are recommended for operation with thin oil and for applications having continually reversing loads.8520L0232 • Rev BD • Nov 2012General, Orbital Motors Technical Information OMRW NBecause of the rollers in the gear rim OMRW N is suitable for continuous operation under demanding operating conditions: e.g. high pressures, thin oil, or frequent rever-sals. The needle bearings of the output shaft make OMRW N suitable for absorbing static and dynamic radial loads.OMEWOMEW motors have a disc valve mounted on the output shaft, i.e. hydraulic and mechan-ical losses are reduced to a minimum and the gearwheel set is fitted with rollers. OMEW is therefore ideal for continuous operation in demanding conditions. The output shaft runs in needle bearings capable of absorbing static and dynamic radial loads. OMEW motors are fitted with a high-pressure seal; therefore the drain line can be omitted.OMS, OMT, OMVOMS, OMT, and OMV are suitable for continuous operation under rough operating conditions: e.g. high pressures, thin oil, or frequent reversals. The tapered roller bear-ings make the motors suitable for absorbing static and dynamic radial loads. Besides the separately driven and hydraulically balanced disc valve, hydraulic and mechanical losses are reduced to a minimum. This gives the motors high efficiency - even at high pressures, and good starting characteristics.TMTThe marked for hydraulic motors has developed generally increasing expectations of the motor performance, and espacially of a higher pressure level. On some applications the present motor program no longer fulfils the marked demand. The TMT motors comply with these expectations providing the same good characteristics as the OMS, OMT and OMV motors.If the application requires very smooth running at low speeds the choice of OMS, OMT, OMV or TMT is recommended.Features of Main Types (continue)Selection of Motor TypeGeneral, Orbital Motors Technical InformationMotor Variants Motor VariantsMotors with corrosion resistant partsOMP and OMR motors are available ina version with corrosion resistant parts:OMP C and OMR C. The corrosion resis-tant parts are: output shaft (1), key (2),front cover (3), and front cover screws (4).The dust seal (5) is of nitrile rubber withstainless steel cap.OMP/OMR with dust seal capOMP and OMR motors are also availablewith a dust seal cap. These motors areparticularly suitable for sweepers, etc.where resistance to high dust concentra-tions is a requirement.Wheel motorOMP, OMR, OMS, OMT and OMV motorsare available in wheel motor versions.The recessed mounting flange makesit possible to fit a wheel hub or a winchdrum so that the radial load acts midwaybetween the two motor bearings.

It can be an advan-tage to use a short motor for gears that already have the capacity to absorb radial and axial forces.Type designations are OMSS, OMTS and OMVS.Ultrashort motorOMS, OMT, OMV and TMT are available with ultrashort installation dimensions, i.e. without bearings and output shaft. The ultrashort design allows an opti-mised integration of the motor in the counterpart. Special installation condi-tions please contact the Sauer-Danfoss Sales Organisation.Type designations: OMSU, OMTU, OMVU and TMTU.Motors with integrated positive holding brakeOMS is available in a version with integral holding brake. This is a drum brake activated mechanically (positive brake). Type designation for OMS with integral holding brake is OMS B.Motors with integrated negative holding brakeOMR motors are available with inte-grated multi-disc brake that is released by hydraulic pressure. The brake motor can be used in closed loop or open loop systems.Type designation: OMR FMotor Variants (continue)151-1188.10Motor VariantsMotor VariantsMotor Variants (continue)Motors with integrated negative holding brakeOMT and TMT with integrated multi-disc brake is available in four versions:OMT FH, OMT FL, OMT FX and TMT FL. The brake is a spring activated multi-disc type that is released by a hydraulic pres-sure. OMT FH can work with high drop pressure [e.g. piloted from a shuttle valve in open loop systems], whereas OMT FL, OMT FX and TMT FL release the brake at low pressure [e.g. piloted from the charge pump in closed loop systems]. OMT FX are particularly well-suited for applica-tions that require very short installation dimensions, - for example in road rollers and wheels.The design of the OMT F and TMT F motors allows the brake to be used as dynamic emergency brake as well.Motors with integrated flushing valve Without any change to their outerdi-mensions, OMS, OMT, OMV and TMT are available with an integrated flushing valve.The integrated flushing valve ensures continuous renewal and cooling of the oil in the closed circuit. The flushing valve is activated by the high pressure side of the motor and allows the flushing flow to pass to the drain line and the tank. Type designation: OMS V, OMT V, OMV V and TMT V .Motors with tacho connectionOMS, OMT and OMV motors are available in a version with tacho drive shaft. With a tacho connection the speed of the motor can be registered.Type designations are OMS T, OMT T andOMV T.Motor Variants (continue)Motor VariantsMotors with speed sensorOMM, OMP, OMR, OMS, OMSW, OMT and OMV are available with integrated speed sensor. The electric output signal is a standardized voltage signal that may for example be used with Sauer-Danfoss' electronic module type EHSC to control the speed of the motor. The speed is registered by an inductive sensor. Signal processing and amplification are integrated in the housing of the sensor. Type designation: OM - EM.OMT N motorOMT is available in a short version with high bearing capacity. The motor is very suitable for the propulsion of road rollers and similar equipment.Type designation: OMT NSelection of Motor SizeSelection of Motor SizeWhen a certain motor type has been selected in accordance with the requirements of the individual application, the size of the motor is determined according to the torque and speed required for the application.For this purpose use the bar chart on the first pages of the subcatalogues and the func-tion diagram for the individual motor.The function diagram for a hydraulic motor shows the relation between operatingtorque M (vertical axis) and speed n (horizontal axis) at different pressure drops ∆p and oil flows Q.The curves for constant pressure drop and constant oil flow form a network superim-posed on the coordinate system grid. The curves for constant power output N (hyperbo -las] and constant total efficiency ηt are also plotted. The latter curves have a ring form, to as on mussel shells. For this reason function diagrams are often called shell diagrams.Build-up of the Function DiagramContinuous operation/intermittent operation/peak loadThe function diagrams are divided up into a dark area A and two light areas B.The dark area A represents the continuous range of the motor. Within this range the motor is able to run continuously with optimum efficiency and operating life.The two light areas B represent the intermittent range of the motor. It is advantageous to make use of the intermittent range when the motor works with varying loads, but also to allow for braking torques when reversing direction.It is permissible to subject the motor to intermittent speed or intermittent pressure drop for max. 10% of every minute. The motor should not be subjected to intermittend speedand intermitend pressure drop at the same time.Build-up of the Function Diagram (continue)The upper limits for intermittent pressure drop and torque must not be exceeded for more than 1% of every minute (peak load). The max. peak load value is stated in the technical data for each type of motor. High pressure peaks occur, for example, whena pressure relief valve opens or a directional valve is opened or closed. Pressure relief valves and dual shock valves should be set so that pressure peaks do not exceed the max. peak values. In systems with large pressure oscillations the pressure and torque peaks should be measured with electronic equipment.To give problem-free operation the motor size should be selected using the permis-sible continuous and intermittent values while making sure that pressure peaks do not exceed the max. peak values.EfficiencyThe total efficiency ηt is the product of the volumetric efficiency (ηv) and the hydraulic-mechanical efficiency (ηhm). Thus ηt = ηv x ηhm.ExampleAn OMS 125 is to drive a shaft at a speed of 375 min-1 (rpm) with an applied torque of 310 Nm [2745 lbf•in].If the volumetric efficiency was 100% the oil quantity would be the geometric displace-ment times the number of revolutions.Theoretical supplied oil quantity:Metric US unitsQ theor =Displ. (cm3) • speed (min-1)(l/min)Q theor =Displ. [in3] • speed [rpm][US gal/min] 1000 231=125.7 • 375∼ 47 l/min =7.67 • 375 ∼12.45 US gal/min1000 231Volumetric efficiencyThe volumetric efficiency is an expres-sion for the proportion of the appliedquantity of oil [as a percentage] that isconverted to output shaft revolutions(speed). The remaining quantity of oil(leakage) is led across clearances andsealing surfaces to act as a lubricant/coolant.When the load (pressure drop) increases,leakage also increases.The quantity of oil supplied to thegearwheel set thus diminishes, and thenumber of revolution (speed) falls.Selection of Motor Sizeof the efficiencyHowever, the actual supplied oil quantity is 50 l/min [13.2 US gal]. The volumetric efficiency can be calculated as follows: MetricUS unitsηv = 47 • 100 ∼ 94%ηv = 12.45 • 100 ∼ 94%5013.2Hydraulic mechanical efficiencyThe hydraulic mechanical efficiency is an expression for the proportion of appliedpressure (as a percentage) that is con-verted to output shaft torque. The remaining pressure is loss; either mechanical loss at low speeds or hydrau-lic loss at high speeds, as can be seen on the torque graph (pressure-drop curve). Mechanical loss is greatest at motor start-up because a film of lubricant hasnot yet been built up on moving parts.After a few revolutions the film is estab -lished and friction is reduced (the curveBuild-up of the Function Diagram (continue)Selection of Motor Sizesteepens). Hydraulic loss is greatest at high speeds because of the high pressure losses in ports and oil channels when oil flow is high. Therefore the pressure drop across the gearwheel set becomes less and the motor yields less torque.OMS 125 has a minimum starting torque of 260 Nm [2300 lbf•in] at a pressure drop of 175 bar [2540 psi], as given in the OMS technical data table. When the lubricant film is established, the motor yields 310 daNm [2745 lbf•in] with the same pressure drop.On the function diagram the pressure drop curve does not intersect the torque axis, but min. starting torque at max. continuous and max. intermittent pressure drop is given in the technical data for each motor type.Example:To calculate the hydraulic-mechanical efficiency ηhm , it is necessary to first read off (mea-sure) the motor torque T mot eff for a given oil flow and given pressure drop. The diagram on page 13 shows that an OMS 125 gives a torque of 310 Nm [2745 lbf•in] for a pressure drop of 175 bar [2540 psi] and an oil flow of 50 l/min [13.20 US gal/min].The theoretical motor torque for the same pressure drop can be calculated as follows: MetricUS unit T theo =Displ. (cm 3) • pressure drop (bar) (Nm) T theo = Displ. (in 3) • pressure drop (psi)[lbf•in] 62.8 6.28MetricUS unitsT theo = 125.7 • 175 ∼ 350 Nm T theo =7.67 • 2540∼ 3102 lbf-in62.8 6.28Dividing the read-off (measured) torque by the theoretical torque gives the hydraulic-mechanical efficiency:ηhm = 310 • 100 ∼ 89% ηhm = 2745 • 100 ∼ 89%3503102Total efficiencyIt is now possible to calculate the total efficiency of OMS 125 at ∆p = 175 bar [2540 psi] and Q = 50 l/min [13.2 US gal/min]: ηt = ηv • ηhm = 94 • 89∼ 84 %100 100With an acceptable degree of accuracy the same total efficiency can be read from thefunction diagram efficiency graphs, page 13.The function diagram is for use when the right Sauer-Danfoss motor (and pumps, etc.) has to be selected for an application.For example, a motor is required with an output:Max. cont. speed: 425 min -1 (rpm) Max. cont. torque: 260 Nm [2300 lbf•in]In the subcatalogues and in the survey brochure the maximum speed and torque of the different motors can be compared. The smallest motor able to meet the requirements is to be found in the OMR or OMS series. But only OMR 125, OMS 125, and OMS 160 can meet both the required speed and torque.The function diagrams for OMR 125, OMS 125 and OMS 160 can now be used. Find the operating point concerned, i.e. the torque on the vertical axis T = 260 Nm [2300 lbf•in], speed on the horizontal axis n = 425 min -1 (rpm).The position of the operating point (T,n) in relation to the curves for constant pressure drop ∆p, constant oil flow Q, and constant total efficiency ηt , gives the following associ-ated values:Selection of Motor SizeBuild-up of the Function Diagram (continue)Use of the Function DiagramBuild-up of the Function Diagram (continue)Selection of Motor SizeWhich is now the most important factor in an overall economic and technical assessment: the initial price of the hydraulic system, its efficiency or its operating life?If the answer is the price of the motor, the choice is an OMR 125. The choice between OMR 125 and OMRW 125 N is made according to the required bearing load.If the efficiency of the motor is all-important, the choice is an OMS 125. The slightly higher initial price of OMS 125 compared with OMR 125 will often be compensated for by a better system design with associated savings in running costs and reduced heat generation. As an additional advantage OMS 125 also requires the least oil flow.When it comes to operating life being the most important factor, the choice is an OMS 160. It has the least working pressure and thereby gives the longest system operating life.When the size of motor has been decided, the capacity of the pump can be determined. If, for example, the choice had been an OMS160 , the pump would have had to be able to deliver 70 l/min[18.49 US gal/min] at 119 bar [1726 psi].If a hydraulic motor is to be installed in an existing system with a given pump, then the choice of motor is largely predetermined.At very low speeds, the motors may run less smoothly. This is why a min. speed is stated for each type of motor. In borderline cases a motor of the desired type should be tested under the required operating conditions in the system concerned before finally selecting the motor size and type.To obtain smooth running at very low speed the motor leakage must be constant. Therefore it is recommended that a motor with disc valve (OMS, OMT, OMV or TMT) be chosen, but avoid choosing motors with the smaller displacements. The best results are achieved with a constant load, a return pressure of 3-5 bar [45-70 psi] and an oil viscosity of min. 35 mm2/s [164 SUS].Minimum SpeedIn many applications the hydraulic motors must absorb both- external radial and axial forces acting directly on the output shaft of the motor (e.g. from the weight of a vehicle)- radial forces produced by torque transfer from gearwheels, chainwheels, V-belts or winch drums.For such applications hydraulic motors with built-in rolling bearings are particularly suit-able. Two different types of bearing are used in Sauer-Danfoss hydraulic motors:1) Needle bearings in OMPW N, OMRW N and OMEW.The needle bearings are capable of absorbing large radial forces. As the motors have separate axial bearings, the operating life of the needle bearings is not affected by the size of the axial load.2) Tapered roller bearings in OMS, OMSW, OMT, OMTW, OMV, OMVW and TMT The tapered roller bearings can absorb large radial and axial forces.The largest possible bearing capacity for the individual motor type is obtained by using OMPW N, OMRW N, OMEW, OMSW, OMTW, or OMVW because the recessed mounting flange makes it possible to fit for example wheel hubs and winch drums so that the radial load is applied centrally to the two bearings.Motor with needle bearingsMotor with tapered roller bearingsBearing DimensioningShaft Load and Bearing Life TimeIt is a general rule that life time and speed are inversely proportional: life is doubled when speed is halved. So life can easily be calculated for other speeds than those given in the sections on shaft load in the individual subcatalogues. The relation is expressed by the formula:L new = L ref x n refn new where L new is the life time at speed n new , and L ref and n ref are the data for the given motor type found in the subcatalogue.Relationship between Bearing Life Time and SpeedBearing DimensioningRelationship betweenShaft Load andBearing Life TimeRelationship between Permissible Shaft Load and SpeedMaximum Radial Shaft Load In certain applications the motor must run at low speeds while the bearings must absorb high loads. This is the case for example when the motors are vehicle support elements. In such cases the following relationship between speed and bearing load (with unchanged bearing life time) must be taken into account:3.3P new = nrefP ref n newP new is the shaft load at n new. P ref and n ref are data from the subcatalogue.For n ref = 200 min-1 [rpm] we have the following table forP new:P refn newmin-1 (rpm)2550100200300400500600700 P newP ref 1.88 1.52 1.23 1.000.880.810.750.720.68The calculations above are solely for bearing life time and load capacity. But there is also a limit to how much load the other parts of the motor (bearing housing, mounting flange and output shaft) can carry. For this reason the maximum shaft load is limited to avoid the risk of mechanical breakdown.The maximum shaft load is shown in the shaft load diagrams for OMPW N, OMRW N, OMEW, OMS, OMT, OMV and TMT motors.Please contact the Sauer-Danfoss sales organisation for hydraulics if motors are to be subjected to shaft loads higher than the maximum, or where there are particularly high dynamic effects (shock factor > 3).Lower shaft loads result in longer life time of the bearings. The exact relationship is shown by the following formula:L new=P ref 3.3L ref P newL new is the bearing life at a shaft load of P new, and L ref and n ref are data from the subcata-logue.Note:- The formula applies to OMPW N, OMEW and OMRW N regardless of the relation between the axial and radial loads.- With the other motors the formula only applies if there is a constant relation between the axial and radial loads.。

丹佛斯压差控制阀说明书

丹佛斯压差控制阀说明书

丹佛斯压差控制阀说明书丹佛斯压力开关KP系列的安装及使用众所周知,在一般的制冷系统中,都会用到高低压力开关,用来控制压缩机的启停、风机启停,从而确保制冷系统的正常运行。

今天和大家简单的交流一下压力开关KP的安装和使用。

KP的安装在托架上或者在纯平表面上安装KP压力控制器。

也可以在压缩机上安装压力控制器。

在不利条件下,角铁托架可能会增强安装平面的振动。

因此在出现强烈振动的地方应始终使用墙装托架。

如果有出现水滴或水雾的风险,则必须使用附带的顶板。

顶板可将外壳的防护等级增加到IPIP 44并且适用于所有的KP压力控制器。

要达到IP 44的防护等级,必须将控制器安装在角铁托架(060-105666)或墙板托架(060-105566)上来盖住其背板上的孔。

包含自动复位功能的所有装置均配有顶板。

带有手动复位的装置也可以使用顶板,但在这种情况下,必须单独购买(单压,代码为060-109766;双压,代码为060-109866)。

如果装置要用在污浊的条件下或者暴露在浓重的水雾中—从顶部或从侧面—则必须安装防护帽。

防护帽可与角铁托架或墙装托架一起使用。

如果装置存在暴露在多水环境中的风险,则当产品安装在特殊IP55外壳中后可达到更高的防IP 55护等级。

IP 55外壳有单压(060-033066)和双压(060-035066)可供选择。

控制器的压力管连接必须始终以正确的方式安装到管路上,即使液体不会聚积在波纹管底部。

尤其是在以下情况下,很可能会出现该风险:装置位于很低的周围环境中时,例如在气流中在管路的底部进行连接时。

这样的液体可能会损坏高压控制器。

因此,压缩机的振动得不到抑制并可能引发触点颤动。

放置多余的毛细管如果发生振动,多余的毛细管可能会破裂并导致失去所有的系统充注物。

因此遵守以下原则便显得非常重要:当直接安装在压缩机上时:固定毛细管,使压缩机/控制器装置作为一个整体一起振动。

必须盘起并扎紧多余的毛细管。

注意:根据EN规则,禁止使用毛细管来连接安全压力控制器。

REG-SA 型和 REG-SB 型手动调节阀 计算和选择 介绍 在制冷设备中,手动调节阀主要在液体管路中使 用,以调节制冷剂流量。此外,该阀门还能作为 膨胀阀使用。从计算的角度看,这两种用于领域 截然不同。 正常流量用指的是经过阀门的流量与阀门压降的 平方根成正比,与制冷剂密度成反比(伯努利方 程)。
阀锥 这些阀门分为两种,带A阀锥的 REG-SA 和带 B阀 锥的 REG-SB。A 阀锥用于扩展管线,B 阀锥用于 调节目的,例如液体管线。 该阀锥可以确保完美的调节,并提供宽阔的调节 区域。不论使用何种制冷剂,都便于获得正确的 容量。阀锥密封环可以最小闭合力提供完美的密 封。 该阀锥可以在轴上转动,因此当阀门打开或关闭 时阀锥和阀座之间没有摩擦。 标注环示例,REG-SA
