压力开关说明书

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。

概述本说明书是关于SOR 压力开关在安装、过程联接、 电气联接和调校方面的说明，此种形式压力开关不 推荐用于存在高冲击压且高频率循环的高液压工作 场合。

注意：如果您发现某台开关有损坏，请尽快与工厂 或SOR 产品当地服务代表联系，以获得返修登记号 码，如果该产品无法返回工厂维修，应由授权的产 品服务代表提供现场服务，请与工厂或SOR 公司当 地服务代表联系技术支持事宜。

设计与规范的改动请恕不另行通知。

电气联接警告：在危险环境下开启防爆型开关，在盖移动前一定要保证电源已被断开，否则会导致严重的个人伤害和巨大的工厂损毁。

在开关壳内防置过多的导线或不当的联接可能会防碍开关正常的工作。

2.不推荐通压力接口或电气接口的在线安装。

3.建议安装位置为电气接口竖直向下，以避免收集冷凝液，尽管如此，开关仍可全位置安装。

保证导线的电气性能符合所有应用的国家和场合，并且根据相关国家和场合的安全要求安装产品。

过程联接采用两个扳手安全地将引压管与压力接口联接：一个扳手夹住六角形压力接口，另一个扳手旋紧引压管或管接头。

重要：小心勿使压力接口松，压力接头从壳体上脱落。

警告：将外壳安装平板表面可能会导致外壳受到扭力，从而使压力开关不能正常工作。

P r e s s u r e s w i t c h e s5ApplicationsAir compressors, water pumps, booster pumps, firefighting equipment, or oil supply equipment .TIVAL pressure switches of the FF 4 series are suitable for a wide range of applications.For example they can be utilized for:n Monitoring and controlling the pressure of liquid or gaseous media in pipelines, tanks, vats, pressure vessels and apparatus.n Applications in process control, cooling, pneumatics and hydraulics.n Pressure monitoring of cooling circuits and lubrication systems on various types of machinery.nAutomatic switching of pump and compressor motors for supplying water to dwellings, booster pumps, firefighting equipment and on compressed air systems.DescriptionThe pressure of the monitored medium operates against a flat diaphragm,b ellows or plunger (depending on pressure range). A system of levers and springs work on a snapaction cascade switch of high vibration resistance, ensuring flutterfree switching. With no pressure on the diaphragm contact 1-2 is closed. This can be used as an …ON“ signal for a pump or compressor motor.If pressure exceeds the upper switchingpoint, contact 1-2 opens and contact 1-4 closes. The connected motor will be switched off. Contact 1-4 is often used to indicate the …off“ condition.Contact 1-2 will close again, when the pressure on the diaphragm hasd ropped below the set lower switchpoint. Upper and lower switch points can be adjusted independently of each other using a screwdriver. The two switch points are indicated on the scale inside the unit.Change-over contact with manual reset min.:If the pressure drops below the set value, contact 1-4 opens and contact 1-2 closes and locks. When the pressure has risen above the set value, thec ontact can be unlocked with the manual reset button.Change-over contact with manual reset max.:If the pressure rises above the set value, contact 1-2 opens and contact 1-4 closes and locks. When the pressure has dropped below the set value, the contact can be unlocked with the manual reset button.Pressure connection, pressure sensing element, switch mechanism ande lectrical terminals are fitted on a die-cast aluminum-alloy base. The scale and switch are protected against environmental effects by an impact-resistant, transparent polycarbonate cover, (CTI 200-225) and can be lead-sealed.Included in standard units: Rubber grommet with orifice for cable e ntry, pressure connector …Y“, made out of plastic for demineralised watera pplications.Options upon request:n G old flashed contacts n C able gland M 20for protection IP 65n V iton diaphragm for aggressive media n M anual resetn G L - approved versionn U L / CSA - approved version n A TEX - approved version n V dS - approved versionFF 4-2, FF 4-4, FF 4-8, FF 4-16, FF 4-32103 mm5,5 mm40 mm 14 mm50 mm 84,5 mm77,5 mm151 mm75,5 mm 40,5 mmaFF 4-12, FF 4-30, FF 4-60,FF 4-120, FF 4-250103 mm5,5 mm40 mm 14 mm 50 mm 84,5 mm77,5 mm151 mm75,5 mm 40,5 mm57 mmControl pressure switch FF 4-...

TerminologyNon-linearityThe largest deviation from the effective characteristic line of an ideal reference line. The reference line can be defined as a limit point adjustment, a BSL or a BSL through 0.Specifications: Non-linearity, HysteresisBSL through ZeroAs an additional requirement for the minimum value adjustment, the BSLthrough zero (also BSL/0) must go straight through zero or the origin.Specifications: Accuracy NLH (BSL through zero)BSL Best Straight LineThe reference line according to the BSL or the minimum value adjustment is placed in such a way that the maximum positive and negative deviations are as small as possible.Specifications: Non-linearity, HysteresisSpecifications: Accuracy NLH (BSL)NLH Non-linearity and HysteresisLargest deviation from the ideal characteristic line (BSL, BSL/0 or limit point). In pressure measuring instruments, the non-linearity and pressure hysteresis are given together at a constant temperature.Temperature Coefficient TCChange of measured value for zero point and span as a result of changes in temperatureLong-term Stability Long-term DriftThe change of accuracy due to aging under certain reference conditions during a certain period of time, typically 1 year.TEB Total Error BandTotal error (root from sum of the square of the deviations) due to measurement deviations (accuracy) and temperature influence (temperature coefficient TC). The temperature influence is usually given in the information across a range larger than that given in the standard (-10 ... +60 °C). Whilst DIN 16086 also continues to add to the long-term stability over a year, the information is subject to ex-works conditions for obvious reasons.12.
