SS-2不同压力开关操作手册说明书

“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.

pc30de压力开关说明书

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。

二、基本组成
pc30de压力开关的基本组成由触发线圈、压力传感器、弹簧和触点组成。

其中触点为一种机械连接，工作于一定工作电压下，主要用于对介质直接施加压力。

对各种材料的压力传感器进行测量和转换。

弹簧与触脚组合在一起，以形成复位操作杆，用于控制开关动作和关闭操作。

弹簧和触脚通过橡胶连接在一起，用于橡胶密封。

触脚通过螺栓固定在弹簧座上。

三、使用注意事项
a.该开关可以工作在极低的工作温度下，且不会产生过大的振动。

b.该开关在工作时不会产生过载，且该设备具有自我保护功能，不会因为意外而损坏。

c.该开关具有压力自锁功能，可防止因误操作造成严重后果。

d.此开关可在零下40度到100度、0度到-50度、-60度到70度条件下工作。
