压力开关设置方法

压力开关设置方法压力开关是一种用于控制和保护压力设备的电气开关设备，广泛应用于空压机、泵浦、供水设备、制冷和空调设备等工业和家用设备中。

通过对压力开关进行设置，可以实现设备的安全工作和自动控制。

下面将详细介绍压力开关的设置方法。

一、压力开关的工作原理压力开关主要由调节弹簧、压力调节螺母和开关机构组成。

当被控制的设备运行时，设备内部产生压力，当压力达到预设值时，压力作用在压力开关的调节弹簧上，使其产生形变。

当形变超过设定值时，调节弹簧会推动开关机构，从而实现开关的闭合或断开。

这样就能够控制设备的运行状态。

二、压力开关的设置步骤1. 确定设备的工作压力范围：在设置压力开关之前，首先需要了解设备的工作压力范围。

可以通过设备的工作手册或技术规格表来了解设备的额定工作压力和最大工作压力。

2. 选择合适的压力开关型号：根据设备的工作压力范围选择合适的压力开关型号。

一般来说，压力开关的额定工作压力应该大于设备的最大工作压力，以保证设备正常运行。

3. 调节开关压力：将压力开关安装在设备上，通过调节压力调节螺母将开关的压力调节到设备所需的工作压力。

调节时可以使用专用的调节工具，逐渐调节螺母，直到达到所需的工作压力。

4. 调节压力差：压力差是指压力开关在开启和关闭状态之间的压力差值。

通过调节压力调节螺母，可以调节压力开关的压力差。

一般情况下，设备需要在达到最小工作压力和最大工作压力之间切换，此时需要调节压力差。

5. 检查压力开关的工作状态：设置完成后，需要对压力开关进行检查，确保其能够正常工作。

可以通过手动加压或减压来观察开关的闭合和断开状态，并在调整过程中进行必要的调整。

6. 定期检查和维护：一旦完成设置，就需要定期检查和维护压力开关。

这包括清洁压力开关的外部和内部，检查调节弹簧和开关机构的正常运行，以及根据设备的使用情况进行必要的调整。

三、注意事项1. 安全操作：在设置压力开关时，必须注意安全操作，关闭设备电源，并使用绝缘手套和工具进行操作，以避免电击和其他安全事故的发生。

SOR液位开关使用说明书

SOR液位开关使用说明书SOR液位开关使用说明书工作原理上升的液面将浮球或弹簧提升式沉筒浮起，带动磁力短管上升至磁场区，吸引并触发电路或气路开关（发出液位到达信号）。

液面下降时，次序相反，电路或气路开关被释开（发出液位下降信号）。

磁力滑块（通过密封套筒）将永久磁铁和开关组件与过程液面隔离，避免磁铁腐蚀和磁力碎屑堆积。

磁力运动传输消除了由机械装置弯曲运动传输带来的疲劳，损坏及过早失效等问题。

磁力运动传输避免了因探杆型传感器引起的表面涂层问题。

在没有工厂允许的情况下，不要改变开关的原件和结构。

沉筒式结构SOR液位开关使用说明书沉筒悬挂在弹簧平衡联动杆上，液面上升时，沉筒的有效重量因受浮力而减小，弹簧回缩拉起连杆，使磁力短管在密封套筒中上升。

磁力短管的向上运动是在外部永久磁铁产生的磁场内，磁力把外部磁铁吸向磁力短管，牢固地吸附在密封套筒上，此时，微动开关被触发。

最新的信息可以登陆查询通过ISO9001认证液面下降时各次序相反，磁力短管下落至磁场外，复位弹簧将外部磁铁拽离密封套管，微动开关复位。

浮球式结构引压口联接外浮筒接管应当平直且不受干扰，控制头与外浮筒垂直中心线在3℃内。

注意：顶装式控制头与容器法兰或短管安装成与容器的垂直或水平中心线不超过3℃。

（即：外浮筒式与顶装式均应垂直安装）接管长度应控制在最小，以使开关整体更稳定。

如有需要，应采用接管悬挂或支承装置。

控制机构在液体中动作，接管中很可能堆积沉淀物，应采用“T”形或“+”形管接头，允许定期清洗接管。

排污阀及吹扫阀可用于清洁外浮筒和接管。

正常运行中，所有接管上阀门应完全打开，因为限流可能导致误动作。

警告：介质温度超过232℃时，不推荐在外浮筒上使用保温材料。

SOR开关说明书

∙SOR液位开关使用说明书∙SOR液位开关使用说明书SOR液位开关基本原理上升的液面将浮球或弹簧提升式沉筒浮起，带动磁力短管上升至磁场区，吸引并触发电路或气路开关（发出液位到达信号）。

液面下降时，次序相反，电路或气路开关被释开（发出液位下降信号）。

磁力滑块（通过密封套筒）将永久磁铁和开关组件与过程液面隔离，避免磁铁腐蚀和磁力碎屑堆积。

磁力运动传输消除了由机械装置弯曲运动传输带来的疲劳，损坏及过早失效等问题。

磁力运动传输避免了因探杆型传感器引起的表面涂层问题。

在没有工厂允许的情况下，不要改变开关的原件和结构。

SOR液位开关沉筒式结构沉筒悬挂在弹簧平衡联动杆上，液面上升时，沉筒的有效重量因受浮力而减小，弹簧回缩拉起连杆，使磁力短管在密封套筒中上升。

磁力短管的向上运动是在外部永久磁铁产生的磁场内，磁力把外部磁铁吸向磁力短管，牢固地吸附在密封套筒上，此时，微动开关被触发。

液面下降时各次序相反，磁力短管下落至磁场外，复位弹簧将外部磁铁拽离密封套管，微动开关复位。

SOR液位开关浮球式结构浮球与一根机械连杆固定在一起，液面上升至浮球，浮力使连杆上升，磁力短管升入密封套筒中，磁力短管的向上运动是在外部永久磁铁产生的磁场内。

SOR液位开关引压口联接外浮筒接管应当平直且不受干扰，控制头与外浮筒垂直中心线在3℃内。

注意：顶装式控制头与容器法兰或短管安装成与容器的垂直或水平中心线不超过3℃。

（即：外浮筒式与顶装式均应垂直安装）接管长度应控制在最小，以使开关整体更稳定。

如有需要，应采用接管悬挂或支承装置。

控制机构在液体中动作，接管中很可能堆积沉淀物，应采用“T”形或“+”形管接头，允许定期清洗接管。

排污阀及吹扫阀可用于清洁外浮筒和接管。

正常运行中，所有接管上阀门应完全打开，因为限流可能导致误动作。

Hi-side system pressure acts on the piston to product force F h . It is counteracted by the adjustable range spring force F s and Lo-side system pressure acting on the backside of the piston to produce force F l . The resultant force F d acts on the piston and overcomes the force of the adjustable range spring [F d = F h – (F l + F s )] and moves a shaft that actuates (deactuates) an electrical switching element.AF hF lF sF dNCNOCDifferential Pressure SwitchPrincipleQuick Selection GuideBasic Series 101/121 differential pressure switches with standard wetted parts are normallysuitable for air, oil, water and non-corrosive processes.

Adjustable range is expressed for increasing pressure: the Set Point must be within the adjustable range. Dead band is expressed as typical at mid-range. See dead band considerations at the bottom of this page.Notes1. Ambient temperature range: -30 to 180o F (-34 to 80o C). Check restrictions, page 7, for optional electrical switching elements and page 9 for optional diaphragm systems.2. Metric bar (mbar) values are practical equivalents of the mathematical conversions. This data appears on the product nameplate when metric engineering units are specified.3. CAUTION: When the process could be considered dirty in terms of suspended particles, it is recommended that 20-micron in-line filters be installed on the Hi and Lo pressure ports.4. To achieve optimum performance, the 101/121 should be calibrated under simulated system operating conditions.Dead Band Considerations1. Dead band values are expressed as typical expected at mid-adjustable range and 50% maximum system pressure (static pressure) using the standard K switching element.2. Dead bands are fixed (non-adjustable), except when T or H switching elements are used.3. A dead band multiplier must be applied to the typical dead band value shown in adjustable range above whenever an optional switching element is specified.4. Dead band can be widened by selecting an optional switching element with a multiplier greater than 1.0.5. Use of metal diaphragms may have additional impact on Dead band values.

This glossary applies to SOR Pressure Switches.Adjustable RangeThe span of pressure between upper and lower limits within which the pressure switch may be adjusted to actuate/deactuate. It is expressed for increasing differential pressure.Dead BandThe difference in pressure between the increasing Set Point and the decreasing Set Point. It is expressed as “typical,” which is an average with the increasing Set Point at mid- adjustable range for a pressure switch with the standard K switching element. It is normally fixed (nonadjustable).Differential Pressure SwitchA bi-stable electromechanical device that actuates/deactuates one or more electrical switching element(s) at a predetermined discrete differential pressure (Set Point) upon rising or falling differential pressure.DPDT Switching ElementDPDT is two synchronized SPDT switching elements that actuate together at increasing Set Point and deactuate together at decreasing Set Point. Discrete SPDT switching elements allow two independent circuits to be switched; i.e., one AC and one DC.The synchronization linkage is factory set, and is not field adjustable. Synchronization is verified by connecting test lamps to the switching elements and observing them go “On” simultaneously at actuation and “Off” simultaneously at deactuationHermetically SealedA welded steel capsule with glass-to-metal, factory-sealed, electrical leads that isolatesthe electrical switching element(s) from the environment.Maximum Differential PressureThe maximum difference in pressure that may be continuously applied between the Hi and Lo (Lo and Hi) pressure ports without causing permanent change of Set Point, leakage or material failure.OverrangeThe maximum input pressure that may be continuously applied to the pressure switch without causing permanent change of Set Point, leakage or material failure.Proof PressureThe maximum input pressure that may be continuously applied to the pressure switch without causing leakage or catastrophic material failure. Permanent change of Set Points may occur, or the device may be rendered inoperative.RepeatabilityThe ability of a pressure switch to successively operate at a Set Point that is approached from a starting point in the same direction and returns to the starting point over three consecutive cycles to establish a pressure profile. The closeness of the measured Set Point values is normally expressed as a percentage of full scale (maximum adjustable range pressure).Set PointThat discrete pressure at which the pressure switch is adjusted to actuate/deactuate on rising or falling pressure. It must fall within the adjustable range and be called out as increasing or decreasing differential pressure. SPDT Switching ElementSingle-Pole, Double Throw (SPDT) has three connections: C — Common, NO — Normally Open and NC — Normally Closed, which allows the switching element to be electrically connected to the circuit in either NO or NC state.Glossary of T ermsDifferential Pressure Switch6.40.25 MIN TO 76.23.00 MAX3/4 NPT(F)(STD)1/2 NPT(F)(OPT)7.10.281/4 NPT(F) HI SIDE1/4 NPT(F) LO SIDEDimensions in this catalog are for reference only.

具体内容，请参考工厂英文版操作手册，如两者内容有出入，以英文版为准。

在校验设定值时，在常压压状态下将压力开关引压口与压力台相应管道对接，要求压力系统必须有压力表等似可以实时观察压力数据的装置。

然后给系统缓慢增压，要求系统增压最高压力不得超过压力开关铭牌上标定的over range值。

当压力值处于量程范围（adjustable range）时，可进行压力开关设定。

设定压力开关时，将开关单元外壳面板打开，用扳手按照压力值得高低旋转设定螺栓即可。

如图
使设定螺栓和刻度盘的对应压力值对齐即可。

压力开关设定完毕，即可安装使用。

将压力开关引压口安装到管道上，信号线由开关单元接出，根据需要连接到控制是或者相关的控制管道上。

接线时，需严格按照说明书进行操作。

如图：
通常情况下，下降报警时接常闭（C-NC）,上声报警接常开（C-NO）。

如果实际使用中发现信号反转，将接线NC与NO对调即可。

Media pressure on the areas of the pistons counteracts the forces of the range springs — each adjustable by a separate adjusting nut — and moves the piston shafts to operate the lever assembly which, in turn, actuates and deactuates the electrical switching element. Each pressure sensing element of the Adjustable Dead Band pressure switch is a force balance piston-actuated assembly sealed by a flexible diaphragm and an o-ring that is static. The only wetted parts are the single pressure port, two diaphragms, and two o-rings all indicated with asterisks (*) in this illustration.Principles of OperationPressure SwitchesNo Pressure:Electrical switching element is deactuated.Pressure greater than decreasing Set Point but less than increasing Set Point.

Contact the factory for the most current information.CSAEnclosure 4 (Weathertight)Pressure SwitchesT est CertificatesPressure Switches Glossary of T erms SOR recognizes that there is no industry convention with respect to terminology and definitions pertinent to pressure switches. This glossary applies to SOR Pressure Switches.Adjustable RangeThe span of pressure between upper and lower limits within which the pressure switch may be adjusted to actuate/deactuate.Dead BandThe difference in pressure between the increasing Set Point and decreasing Set Point. Decreasing Set PointThat discrete pressure at which the pressure switch is adjusted to deactuate on falling pressure. It must fall within the adjustable range. Hermetically SealedA welded steel capsule with glass-to-metal, factory-sealed, electrical leads that isolatesthe electrical switching element(s) from the environment.Increasing Set PointThat discrete pressure at which the pressure switch is adjusted to actuate on rising pressure. It must fall within the adjustable range. OverrangeThe maximum input pressure that may be continuously applied to the pressure switch without causing permanent change of Set Point, leakage or material failure.Pressure SwitchA bi-stable electromechanical device that actuates/deactuates one or more electrical switching element(s) at a predetermined discrete pressure/vacuum (Set Point) upon rising or falling pressure/vacuum.Proof PressureThe maximum input pressure that may be continuously applied to the pressure switch without causing leakage or catastrophic material failure. Permanent change of Set Point may occur, or destruction of the device may be rendered inoperative.RepeatabilityThe ability of a pressure switch to successively operate at a Set Point that is approached from a starting point in the same direction and returns to the starting point over three consecutive cycles to establish a pressure profile. The closeness of the measured Set Point values is normally expressed as a percentage of full scale (maximum adjustable range pressure). SPDT Switching ElementSingle-Pole, Double Throw (SPDT) has three connections: C — Common, NO — Normally Open and NC — Normally Closed, which allows the switching element to be electrically connected to the circuit in either NO orNC state.DPDT Switching ElementDPDT is two synchronized SPDT switching elements which actuate together at increasing Set Point and deactuate together at decreasing Set Point. Discrete SPDT switching elements allow two independent circuits to be switched;i.e., one AC and one DC.The synchronization linkage is factory set, and is not field adjustable. Synchronization is verified by connecting test lamps to the switching elements and observing them go “On” simultaneously at actuation and “Off” simultaneously at deactuation.|913-888-2630|Registered Quality System to ISO 900111/15 Form 281 (10.21) ©SOR Inc.Registered Quality System to ISO 9001 | 913-888-2630 | 12/15Form 281 (10.21) ©SOR Inc.Dimensions in this catalog are for reference only.
