HED8 类型的液压-电气压力开关是柱塞式压力开关。它们的基本构成是壳体带柱塞的安装套件、压缩弹簧、调节元件和微动开关。
如果要监测的压力低于调定压力，则操作微动开关。要监测的压力通过节流孔传到柱塞。柱塞受弹簧座支持并克服压缩弹簧不断变化的作用力。弹簧座将柱塞的运动传输到微动开关，并在达到调定压力时释放后者的压力。这会打开或关闭电路，具体取决于电路设置。弹簧座的机械前挡块在压力突然降低和过压的情况下，可保护微动开关免于受到机械损伤，并防止压缩弹簧的固态压缩。
注意：
要延长使用寿命，安装压力开关时应确保振动较小，使其免于受到液压冲击。

液压系统中的压力控制阀
在液压系统中,压力控制阀可以调定系统主回路或分支回路的压力.按照功能分类,常用的压力控制阀有溢流阀,减压阀,顺序阀和压力继电器等.这些压力控制阀结构上相似,但性能有差别,在系统中的作用也不尽相同.搞清它们的区别与联系,对于学习压力控制回路以至液压系统的分析广片常重要的。
一,溢流阀
功能 溢流阀的功能是通过阀口溢流,使被控系统或回路的压力保持稳定,实现稳压,调压或限压的作用.
特点 按照结构,溢流阀有直动式和先导式两种.对于直动式溢流阀,当压力较高,流量较大时,要求调压弹簧有很大的刚度,调节性能较差,而滑阀的泄漏也使高压控制难以实现,故只能用于低压小流量场合.先导式溢流阀的特点是用先导阀控制主阀,在溢流阀主阀溢流时,溢流阀进口压力可维持为由先导阀弹簧所调定的定值.先导式溢流阀的另一特点是具有远程控制口,可很方便地实现系统卸荷或运程调压。
溢流阀的泄漏油或流经先导阀的油液在返回油祚时有内泄和外泄两种方式.内泄时泄漏油流经的弹簧腔或先导阀弹簧座通过阀体内的连接通道与出油口和通,而外泄是泄露油或流经先导阀的油液被直接单独引回油箱。
应用 溢流阀的主要用途:(1)在定量泵的出口并联溢流阀可调节泵的出口压力;(2)在变量泵的出口并联溢流阀可对系统起到过载保护作用;(3)在回油路上搂入直动式溢流阀可使执行元件运动平稳;(4)利用先导式溢流阀的远程控制口可实现系统卸荷或远程调压.总之,在系统中溢流阀可作为溢流阀,安全阀,背压阀使用,可以调节系统的压力或使系统卸荷.
二,减压阀
功能 减压阀的功能在于使流经减压阀的油液压力降低,并使与减压阀出口连接的回路压力保持稳定.即减压阀的出口压力可维持恒定,不受进口压力及通过流量的影响。
特点 按照结构减压阀也有直动式和先导式两种,分别用于不同场合.
碱压限的阀心处在原始位置上时,它的阀口是打开的,阀的进,出口沟通.阀心由出口处的压力控制,出口压力未达到调定压力时阀口全开,阀心不动.当出口压力达到调定压力时,阀心上移,阀口关小,在调定压力下达到平衡.当减压阀的出口处不输出油液时,它的出口压力仍能够基本保持恒定,此时有少量油液经先导阀流回油箱。
减压阀与溢流阀的主要区别为:(1)减压阀能保持出口处的压力基本不变,而溢流阀则保持进口处的压力基本不变;(2)在不工作时,减压阀的进出油口互通,溢流阀的进出油口不通;(3)减压阀要求外泄,其先导阀的弹簧腔需通过泄油口单独外接油箱,而溢流阀允许内泄,其先导阀弹簧腔通过阀体内的连接通道与出油口相通,不必单独外接油箱。
应用 减压阀主要用于降低系统某一支路的油液压力,在同一系统中得到两个或多个不同压力的回路.常用于夹紧支路,润滑支路或电液动换向阀的控制回路.需要注意的是减压阀具有压力损失,当分支油路比主油路的压力低很多,且流量较大时,可考虑采用高,低压泵分别供油.
三,顺序阀
功能 顺序阀的功能在于利用液压系统中的压力变化,控制油路通断来控制多个执行元件的顺序动作
特点 按照结构,顺序阀也有直动式和先导式两种.直动式顺序阀结构简单,动作灵敏但调定压力较低,较高压力时宜采用先导式顺序阀.根据控制压力来源的不同,顺序阀有内控式和外控式之分,请注意两者图形符号的区别.内控式顺序阀在进油路压力达到设定压力之前,阀口一直是关闭的,达到设定压力后阀口打开,使压力油进入油路;外控式顺序阀阀口的开闭与油路进口压力无关,仅取决于控制油路压力的大小。
顺序阀与溢流阀的主要区别为:(1)当顺序阀的出口与负载油路相通时,泄漏油和先导控制油必须外泄,而溢流阀的出口与回油相通,泄漏油和先导控制油可外泄也可内泄;(2)溢流阀的进口压力是限定的,即阀的调定压力,顺序阀的进口压力由负载决定,顺序阀开启后可随负载增加市进一步升高.
应用 顺序阀的主要用途为:(1)控制多个执行元件的顺序动作;(2)内控式顺序阀可作背压阀使用;(3)与单向阀并联组成平衡阀,锁定执行元件;(4)外控顺序阀可用于双泵供油系统的卸荷.
四,压力继电器
压力继电器是利用液体压力信号控制电气触点通断的液压电气转换元件,当油液的压力达到其设定压力时,压力继电器发出电信号,以控制电气元件动作,实现执行元件的顺序动作或系统的安全保护和动作互锁。

液压是机械行业、机电行业的一个名词。液压可以用动力传动方式， 成为液压传动。液压也可用作控制方式，称为液压控制。
液压传动是以液体作为工作介质，利用液体的压力能来传递动力。
液压控制是以有压力液体作为控制信号传递方式的控制。用液压技术构成的控制系统称为液压控制系统。液压挖制通常包括液压开环挖制和液压闭环控制。液压闭环挖制也就是液压伺服控制，它构成液压伺服系统，通常包括电气液压伺服系统(电液伺服系统)和机械液压同服系统(机液伺服系统，或机液伺服机构)等。
一个完整的液压系统由五个部分组成，即能源装置、执行装置、控制调节装置、辅助装置、液体介质。液压由于其传递动力大，易于传递及配置等特点，在工业、民用行业应用广泛。液压系统的执行元件(液压缸和液压马达)的作用是将液体的压力能转换为机械能，从而获
得需要的直线往复运动或回转运动。液压系统的能源装置(液压泵)的作用是将原动机的机械能转换成液体的压力能。
液压系统组成
一个完整的液压系统由五个部分组成，即动力元件、执行元件、控制元件、辅助元件和工作介质。
动力元件的作用是将原动机的机械能转换成液体的压力能。动力元件指液压系统中的液压泵，它向整个液压系统提供动力。液压泵的结构形式一般有齿轮泵、叶片泵、柱塞泵、螺杆泵。
执行元件的作用是将液体的压力能转换为机械能，驱动负载作直线往复运动或回转运动。执行元件有液压缸和液压马达。
挖制元件(即各种液压阀)在液压系统中控制和调节液体的压力、流量和方向。
根据控制功能的不同，液压阀可分为压力控制阀、流量挖制阀和方向控制阀。压力挖制阀又分为溢流阀(安全阀)、减压阀、顺序阀、压力继电器等:流量控制阀包括节流阀、调整阀、分流集流阀等:方向控制阀包括单向阀、液挖单向阀、梭阀、换向阀等。根据控制方式不同，
液压阀可分为开关式控制阀、定值控制阀和比例控制阀。
辅助元件包括蓄能器、过滤器、冷却器、加热器、油管、管接头、油箱、压力计、流量计、
密封装置等，它们起连接、储油、过滤和测量油液压力等辅助作用
工作介质是指各类液压传动中的液压油或乳化液，有各种矿物油、乳化液和合成型液压油等
几大类。液压系统就是通过其实现运动和动力传递的。
液压元件可分为动力元件和挖制元件以及执行元件三大类。尽管都是液压元件，它们的自身
功能和安装使用的技术要求也不尽相同，现分别介绍如下:
动力元件:指的是各种液压泵，齿轮泵、叶片泵、柱塞泵、螺杆泵。
1、齿轮油泵和串联泵(包括外啮合与内啮合)两种结构型式。
2、叶片油泵(包括单级泵、变量泵、双级泵、双联泵)。
3、柱塞油泵，又分为轴向柱塞油泵和径向柱塞油泵，轴向柱塞泵有定量泵、变量泵、(变量泵又分为手动变量与压力补偿变量、伺服变量等多种)从结构上又分为端面配油和阀式配油两种配油方式，而径向柱塞泵的配油型式，基本上为阀式配油。);
执行元件:液压缸和液压马达，液压缸有活塞液压缸、柱塞液压缸、摆动液压缸、组合液压缸:液压马达有齿轮式液压马达、叶片液压马达、柱塞液压马达:
控制元件:方向控制阀、单向阀、换向阀;
压力控制阀:溢流阀、减压阀、顺序阀、压力继电器等:
流量控制阀:节流阀、调速阀、分流阙:
辅助元件:除上述三部分以外的其它元件，包括压力表、滤油器、蓄能装置、冷却器、管件{主要包括:各种管接头 (扩口式、 焊接式、卡套式，sae法兰)、高压球阀、快换接头、软管总成、测压接头、管夹等}及油箱等，它们同样十分重要。
