机械式压力开关使用说明书

双簧机械压力开关调节说明书双簧机械压力开关是一种常用的压力控制装置。

其作用是监测压力，当压力达到一定设定值时，开启或关闭电路。

这种开关特别适用于工业、农业和家庭设备中，需要对压力进行监测和控制的场合。

本文将详细介绍双簧机械压力开关的调节方法。

1. 调节压力范围首先，我们需要设计和调整双簧机械压力开关的压力范围。

压力范围的选择取决于所监测的对象的性质和压力大小。

假设我们要监测某个压缩空气罐内的压力，首先要知道该罐的压力最高可以达到多少，然后设置开关的开关量。

这里需要注意的是，双簧机械压力开关的压力范围是可调的。

我们可以通过旋转调节螺母调整最小压力值，并通过旋转调整螺柱调整最高压力值。

2. 调节压力差除了压力范围，我们还需要调节压力差。

压力差是指在压力测量过程中，开关的下限压力和上限压力之间的差值。

这种差异通常可调，以保证开关闭合的准确性。

要调节此参数，我们可以使用压力表来测量压力，并通过旋转调整螺柱或螺母来调整压力差值。

3. 连接电路调整好的双簧机械压力开关需要连接电路，以便于监控和控制压力。

我们可以根据设备的工作需求来设计电路。

电路的安装需要注意的是，在使用中请避免过度施加力量，以免机械部件损坏。

4. 维护和保养在使用中，双簧机械压力开关需要定期进行维护和保养。

首先，要确保机械部件清洁和润滑，以保证其正常运转。

其次，需要检查电路的连接情况和电路电源的稳定性，以确保其正常工作。

如果发现机械故障，请立即维修或更换。

综上所述，双簧机械压力开关是一种可靠的压力控制装置。

正确地调整其参数不仅能确保设备的稳定运行，还能延长其使用寿命。

使用过程中，我们需要定期进行检查和维护，以保证其正常工作。

“SS-2 DIFFERENTIAL PRESSURE SWITCH OPERATION MANUAL OMP# 4202XDX000The pressure switch “BLOCK AND BLEED” action is the same when the instrument pressure is connected to the “LO IN” port and “HI IN” port is left unused. For this mode of operation, the switch acts as a normally closed valve and is called a low switch. When normal differential pressure is acting on the piston, the center O-ring on the spool is between the “HI IN” port and the “OUT” port thus preventing the instrument pressure from passing to the “HI PORT” of the switch body, but allowing it to flow from the “LO IN” port to the “OUT” port of the switch body. When the differential pressure decreases to an abnormal level, the spring force shifts to the spool and the middle o-ring on the spool becomes positioned between the “LO IN” port and “OUT” port. Pressure at the “LO IN” port is “BLOCKED” from entering the “OUT” port and pressure at the “OUT” port “BLEEDS” to atmosphere from the “HI IN” port. The Ruelco “SS-2” pneumaticdifferential pressure switch is a threeway block and bleed valve that isoperated by pressure acting on a pistonopposing an adjustable spring force. Itfunctions as either a normally closed ornormally open valve depending onthrough which the two ports theinstrument pressure is supplied. Theseports are marked as “HI IN” or “LO IN”on the switch body. The output port,marked “OUT” on the switch body, isthe same for either mode of operation.The difference between the pressuresacting on the upstream and downstreamsensing ports is the differential pressurewhich causes the valve to operate.When the instrument supply pressure isconnected to the “HI IN” port, the switchoperates as a normally open valve and iscalled a high switch. If the differentialpressure acting on the piston is at normallevels, it is insufficient to overcome thespring force. The middle o-ring on thespool is positioned between the “LO IN”and the “OUT” port, thus preventing theinstrument pressure from passing to the“LO IN” port of the switch body, butallowing it to pass from the “HI IN” portto the “OUT” port. When the differentialpressure acting on the piston becomeslarge enough to overcome the springforce, the spool shifts and the center o-ring moves between the “HI IN” portand the “OUT” port. Instrument pressure at the “OUT” port and downstream “BLEEDS” to atmosphere thru the “LO IN” port while supply pressure at the “HI IN” port is blocked from entering the “OUT” port.Changing the differential pressure value when the switch is used as either a high or low is done by altering the force of the spring. Changing the spring force is accomplished by turning the spring cap to increase or decrease the spring compression.2.0 INSTALLATION: 2. Small pliers.3. High quality silicone base lubricant.The “SS-2” differential can be panel mounted (with optional panel mount nut) or supported by piping from the sense port in either vertical or horizontal positions. If the switch is mounted horizontally, it is recommended that the small vent hole in the side of the switch body be oriented in a downward position. This will prevent any debris from accumulating in the spring cavity or above the sense piston. 4. An appropriate safety solvent. 3.1 PARTIAL DISASSEMBLY A) Spring Removal3.1.1)If the switch is installed in an operating instrument system, it is not necessary to remove any instrument supply or sense pressure. If the unit is a high switch, it will trip when changing the spring; if it is a low switch, then it will not. So precautions should be taken to avoid any unwanted reactions in the instrumentation system.Proper pipe thread sealant should be used on any pipe fittings threaded into the pressure switch ports. If stainless steel fittings are used, a sealant that will prevent galling is required. The supply gas flowing through the switch body should be filtered and free of large particles. If compressed air is used, it does not have to be lubricated. If natural gas is used as the instrument pressure, then it should contain as little condensate or crude oil as possible. This will extend the life of the seals. When the switch is mounted using the 1/4” NPT base connection and the instrument pressure ports are not in the desired position after the base connection is adequately tightened, DO NOT loosen the body from the base to re-position the ports. Instead, remove the switch and re-make the 1/4” NPT connection.3.1.2) To obtain access to the spring(Item 2), rotate the lock ring (Item 4) clockwise to loosen it from the spring cap (Item 1).3.1.3) Rotate the spring cap (Item 1)counterclockwise until it is disengaged from the switch body (Item 8).3.1.4) Remove the spring from itscavity in the switch body.3.0 DISASSEMBLY (See Spec Sheet)3.1.5) Follow the procedures in repairand assembly section (Steps 4.1.4 and 4.14) of this manual to re-install the spring.Tools and materials required for proper disassembly, repair and assembly are as follows: 1. 7/8” and 1” open end wrenchesor two crescent wrenches of adequate size.B)Piston Removal3.1.6)If the switch is panel mounted, itis not necessary to remove itfrom the panel. It will benecessary to disconnect anypiping or tubing from the basethat would prevent the base frombeing removed. When the switchis supported by the ¼” NPTconnection on its base (Item 12),disconnect any piping or tubingfrom the switch body that wouldprevent its removal from theswitch base. CAUTION: Be surethat all instrument or sensepressures are completely bled tozero before disconnecting anypiping or tubing.3.1.7)Use the appropriate wrenches tohold and loosen the base from theswitch body.

ELECTRIC CONNECTION (diagram B)The electric connection must be performed by qualifi ed personal in compliance with regulation of each country.Before doing manipulations inside the device, it must be disconnected from the electric supply.Wrong connection could spoil the electronic circuit.The manufacturer declines all responsability in damages caused by wrong connections.Check if power supply is between 115-230V.If you have purchased the unit without cables follow diagram B:• Use cables type H07RN-F 3G1 or 3G1,5 with section enough to thepower installed.• Do the pump connection U, V and .• Do the power supply connection L1, N and .• The earth conductor must be longer than the others. It will be the fi rst one to be mounted during the assembly and the last one to be dis-connected during the dismantling. T he earth conductors connec-tions are compulsory!CONTROL PANEL (diagram C)The meanings of the different control panel elements are summarized on the following tables, where:• O means lit LED light.• ( ( O ) ) means slow-fl ashing.• (((O))) means fast-flashing.STARTUP (diagram C)Before starting the device please read the previous sections, espe-cially “Hydraulic Installation” and “Electrical connection”.Follow next steps:1. Start the device by pressing .2. Only for type SG12 set the pump rated current intensity value.- Press during 3 seconds.- The current intensity value is displayed on screen, LED A lights up and display is fl ashing.- By mean of and is adjusted the rated current refl ected in the characteristics plate of the motor. See Note 1.- Press for validation.3. Set the cut-in (start) pressure:- Press during 3 seconds.- The start pressure value is displayed on screen, LED START lights up and display is fl ashing.- By mean of and is adjusted the start pressure from 0,5 to 7 bar.- Press for validation.4. Set the cut-out (stop) pressure:- Press during 3 seconds.- The stop pressure value is displayed on screen, LED STOP lights up and display is fl ashing.- By mean of and is adjusted the stop pressure from 1 to 8 bar.- Press for validation.5. The unit is ready to operate but more optional adjustments can be set through basic and advanced MENUS. See the next chapter.Remark 1: it is important to introduce exactly the rated current specifi ed on the nameplate of the pump.BASIC MENU + (diagram C)- Press simultaneously + during 5 seconds.- By mean of or the values can be changed.- Press for validation.ADVANCED MENU + +- Press simultaneously + + during 5 seconds.- By mean of or the values can be changed.- Press for validation.Remark 2:Basic SWITCHGENIE can only detect dry-running operation through the minimum pressure. This means that plumber must determine the water column of the installation, the start pressu-re of the pump and place the minimum pressure below the start pressure.It can also occur that pumping system is running out of its curve so that the pump is unable to provide the minimum pressure because the fl ow requirement is excessive. In this case SWITCHGENIE would activate a false dry-running alarm.If these concepts are not clear, it is preferable not confi gure this protection or install the SWITCHGENIE 12 with accurate and easy setting of dry-run detection.SYNCHRONISATION (ONLY FOR SWITCHGENIE 12)SWITCHGENIE 12 can be synchronized to another unit SWITCHGENIE 1managing and protecting 2 pumps operating in cascade with alternated starting sequence. Next steps must be followed:1. SET identical cut-in and cut-out pressures in both units.2. GO TO ADVANCED MENU: + +- In step 2in the other unit (this one will be the slave).- In step 3: select identical parameters of differential d.XX.3. Press repeatedly until exit the ADVANCED MENU.4. Press in order to disable the units. Is displayed “OFF”.5. Press again in both units in order to activate the synchronization.Remark 3: after 10 cycles the unit confi gured E01 will display pressu-re and the unit confi gured E02 will display current in Amps.ACCURATE DRY-RUNNING DETECTION (diagram C)In the SWITCHGENIE 12 model it is enough to set the rated current of the pump in order to activate the overcurrent and dry-running protection. However, the accuracy of dry-running detection can be improved by the activation of DR1 parameter in the ADVANCED MENU. The following steps must be followed:1. Drain the hydraulic installation and verify that the hydropneumatic tank is infl ated to the required pressure.2. Go to the ADVANCED MENU:- Press simultaneously + + during 5 seconds.- Press 7 consecutive times to accept and go to the next step until reaching dr0.- Using , set dr1.3. Press and close all the valves.4. The pump will start, will fi ll the installation and will stop at the cut-out pressure.5. Now, SWITCHGENIE 12 knows the current consumption curve of the pump.If you install a new pump this process should be repeated.If you enter the CURRENT INTENSITY MENU by pressing for 3 seconds all this process is invalidated because is predominant the rated current manually introduced.PRESSURE SENSOR CALIBRATIONIn case of wrong lecture of the pressure sensor it can be adjusted again. For the pressure sensor calibration is necessary to have a pressure gauge in the installation. Proceed following next steps:ZERO REGULATION1. Open the taps living the hydraulic net without pressure.2. Press simultaneously the buttons and until the display show0.0 fl ashing.3. Press to validate.FULL SCALE1. Start the pump until cut-out of the pressure switch.2. Press simultaneously the buttons and till the display fl asheswith a fi gure.3. Adjust the pressure with the arrows push-buttons to get the pressuredesired.4. Press to validate.Remark 4: pressure sensor decalibration should not be a normal event. If it is frequently repeated contact the technical service.

pc30de压力开关说明书
pc30de压力开关(pc30d)是一种无源电磁触点式开关，具有超灵敏的压力感受器和阻尼转换器。

根据介质(protected particle)的不同，可选用以下类型：1.用于气体、液体等介质中；2.用于真空下工作的压力开关。

一、开关工作原理
在机械开关中，触点是指施加于气体、液体等介质的运动状态的触点。

压力开关所需的压力感受器，工作原理如下：当设备启动时，感应头接触高压信号而带动电磁缸高速旋转，同时触点上压紧弹簧使之产生回旋，带动压紧弹簧及压力传感器；当压力升高时，被控介质将释放出巨大的扭矩带动电磁缸高速旋转；当压力降低时，压力感受器弹簧产生一定的回旋，通过弹簧力的作用使被控介质释放气体或液体（或者蒸汽);压力改变时触点上压紧力自动改变感应头位置和大小。
