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. Unthread the basecompletely from the switch body. 3.1.8)Unthread the lower housing(Item 18) from the baseassembly. Use appropriatewrench to loosen the hex nutItem 19) from the shaft-pistonassembly.3.1.9)Remove the installed cup seal(Item 16) from the piston (Item17).3.1.10)Procedure for re-installing thepiston cup seal and the shaft sealis in the repair and assemblyprocedure of this manual.3.2FULL DISASSEMBLYNOTE: Use the following instructions to completely disassemble the pilot for repair and cleaning. CAUTION: Be sure that all instrument or sense pressures are completely bled to zero before disconnecting any piping or tubing.3.2.1)Follow the procedures statedunder partial disassembly toremove the spring and piston.3.2.2)Remove the spool (Item 8) fromthe switch body. If it isnecessary, use the small pliersand grip the large end of thespool.3.2.3)The seals on the spool, (Item 8)may now be replaced as perinstructions given in the repairand assembly section of thismanual.4.0REPAIR AND ASSEMBLY(See product data sheet forreplacement part numbers).4.1)Remove the seals from the spooland piston.4.2)Clean all parts using anappropriate safety solvent.4.3)Inspect the spool for any majordamage such as burrs or nicks onits outside diameter. Also inspectit for straightness. Replace thespool (Item 10) if damaged.4.4)Examine the polished bores ofthe switch body (Item 8) andbase (Item 12) for gouges andrough surfaces. Be sure that allheavy dirt deposits have beenremoved. Replace any damagedpieces.4.13) Install the lock ring onto theswitch body and place the spring plate into the body cavity. NOTE : If the switch is panel mounted, install it into the panel and secure with a panel mounting ring prior to installing the lock ring (Item 4) and spring plate (ITEM 6). 4.5)Replacement seals from an authentic RUELCO REPAIR KIT is recommended to ensure proper switch performance. 4.6)Install new seals on the spool and lightly lubricate the seals and spool. CAUTION: Do not leave excessive lubricant on the spool. Doing so may prevent the switch from operating.4.14) Install the spring into the switchbody. CAUTION : Verify that the spring is the proper color for the range required as shown on the Range Selection Chart on the Specification Sheet $XXXX-12-95. 4.7)Verify the required switch range from the Range Selection Chart on the specification sheet 4XXX-12-95.4.8) Install the required cup seal (Item 16) on the large piston and the o-ring on the shaft (Item 20).4.15) Thread the spring cap onto theswitch body. Adjust the switch operation as per user requirements and methods.4.9)Lightly lubricate the piston seal and piston. DO NOT over lubricate or the switch performance may be adversely affected.4.10) Install the spool completely intothe switch body. Move it in and out of the body approximately ¼” to check that it moves freely.4.11) Install the shaft in to the pistonand tighten the hex nut. Install the shaft-piston assembly into the lower housing (Item 18) and grip the shaft on the shaft-piston assembly with the small pliers and move the piston back and forth in the base to verify that it moves freely.

压力开关的工作原理

压力开关的工作原理压力开关是一种常用的工业自动化控制元件，广泛应用于各种机械设备和工艺过程中。

它能够根据被控制系统的压力变化来实现自动控制和保护功能。

下面将详细介绍压力开关的工作原理。

一、压力开关的结构组成压力开关通常由压力感应元件、弹簧机构、触点系统、外壳等组成。

1. 压力感应元件：压力感应元件是压力开关的核心部件，它能够将被测介质的压力转换成机械位移或电信号。

常见的压力感应元件有弹性膜片、弹簧管和差压传感器等。

2. 弹簧机构：弹簧机构主要用于提供压力开关的灵敏度和动作力。

根据不同的应用场景和要求，弹簧机构可以采用单弹簧、双弹簧或叶片弹簧等形式。

3. 触点系统：触点系统是压力开关的输出部分，它能够根据压力开关的动作状态进行开关控制。

触点系统通常由固定触点和动触点组成，其中固定触点固定在压力开关的外壳上，动触点则随着压力的变化而产生动作。

4. 外壳：外壳是压力开关的保护壳体，能够起到防尘、防水和防爆等作用。

外壳通常采用金属材料制成，具有良好的机械强度和耐腐蚀性能。

二、压力开关的工作原理压力开关的工作原理可以分为机械式和电子式两种。

1. 机械式压力开关的工作原理：机械式压力开关通过压力感应元件和弹簧机构实现对压力的感知和控制。

当被测介质的压力超过或低于设定的阈值时，压力感应元件会产生相应的机械位移，使得弹簧机构发生变形。

当弹簧机构的变形达到一定程度时，触点系统会发生动作，从而实现对被控制系统的开关控制。

以过压保护为例，当被测介质的压力超过设定的上限值时，压力感应元件会产生机械位移，使得弹簧机构变形。

当弹簧机构的变形达到一定程度时，触点系统会闭合，从而切断电源或触发报警信号，实现对被控制系统的保护。

2. 电子式压力开关的工作原理：电子式压力开关通过压力感应元件和电路系统实现对压力的感知和控制。

压力感应元件将被测介质的压力转换成电信号，经过放大、滤波和比较等处理后，驱动电路系统控制触点的开关状态。

电子式压力开关具有高精度、可调性好和抗干扰能力强等优点，广泛应用于精密仪器、自动化设备和工艺控制系统中。

Pressure switch, type CS
Data sheet
Description
INDUSTRIAL CONTROLS IC.PD.P10.H 1.02 - 520B 2198
Pressure switch type CS is part of the Danfoss pressure control range. All CS pressure switches have a built-in pressure-operated, three-pole or one-pole switch, the contact position of which depends on
− the pressure in the connector − the range setting.
The pressure switches are ﬁ tted with a manual switch that will lock the contact system in the open position independently of the pressure in the system.
CS product range
• Standard CS pressure switches − pressure connection: G ½ or G ¼
• CS pressure switches with special pressure connection made of polyacetal
− suitable in drinking water applications − pressure connection: G ½
Stop pressure range
Pressure switches are supplied in the following three versions:
− low-pressure, 2-6 bar
− intermediate pressure, 4-12 bar − high-pressure, 7-20 bar.
Contact system
Three-pole (TPST), contact system which opens on rising pressure. The contact system is touch-safe with open terminals, self-lifting terminal screws and star/slot screws.
Cable entry
The pressure switches have threads for two PG 16 screwed cable entries.
Screwed cable entries
Screwed cable entries are supplied with single pack CS pressure switches. Screwed cable entries for CS in industrial packs must be ordered separately under code no. 031E029366 containing seals and Pg 16 nuts.
Pressure relief valve
This valve relieves pressure on the compressor piston. It can be supplied as an accessory and must be ordered separately. The valve has an M10 x 1 external thread, union nut and cutting ring. The nut and cutting ring are both available in 6 mm and 1/4 inch sizes.
Manual switch
When the manual switch has been used to lock the contact system in its open position, the cover can be removed without the plant starting.
Enclosure
The enclosure is made of plastic (PA 6) and is obtain-able in IP 43 or IP 55 versions to IEC 529. A knockout in the base of the enclosure can be removed to provide a drain hole for condensate.
Application
The CS pressure switch is used for the auto-matic start and stop of − air compressors
− pumps for pressure water systems (pressure storage tanks).The CS with pressure relief valve is used in
compressed air systems where pressure relief on the compressor piston before start is required.
