在液压设备中,以压力作为控制信号来实现自动化控制的控制方式中,压力继电器是重要的元件之一。它是一种将油液的压力信号中转换成电信号的电液控制元件(液电转换开关)。当液压系统中的油液压力达到压力继电器的调节压力时,即发出电信号,以控制电磁铁,电磁离合器,继电器等电气元件动作,使油路换向卸压。执行机构实现顺序动作,或关闭电机,使系统停止工作,起安全保护作用等。
压力继电器有直动型和先导型;也有带延时调节和不带延时调节的; 也有弹簧调节型和开关位置调节型。各种压力继电器尽管类型不同,原理只有一个,即靠液体压力与弹簧力的平衡,使柱塞或杠杆产生一定的位移,将电气开关接通与断开。压力继电器的任务是把系统某 较稳定的压力信号反映出去, 以控制其它的顺序动作,但它由于自身和外界的原因,有可能发出误信号,影响液压系统的工作可靠性和安全性。

液压传动技术已经广泛应用于很多工程技术领域,由于液压系统所服务的主机的工作循环、动作特点等各不相同,相应的各液压系统的组成、作用和特点也不尽相同。以下通过对几个典型液压系统的分析,进一步熟悉各液压元件在系统中的作用和各种基本回路的组成,并掌握分析液压系统的方法和步骤。
阅读一个较为复杂的液压系统图,大致可按以下步骤进行:
(1)了解设备的工艺对液压系统的动作要求;
(2)初步游览整个系统, 了解系统中包含有哪些元件,并以各个执行元件为中心,将系统分解为若干子系统。
(3)对每一子系统进行分析,搞清楚其中含有哪些基本回路,然后根据执行元件的动作要求,参照动作循环表读懂这一子系统。
(4)根据液压设备中各执行元件间互锁、同步、防干涉等要求,分析各子系统之间的联系。
(5)在全面读懂系统的基础上,归纳总结整个系统有哪些特点,以加深对系统的理解。

液压系统的组成及其作用
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(附件)和液压油。
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，指液压系统中的油泵，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、叶片泵和柱塞泵。
执行元件(如液压缸和液压马达)的作用是将液体的压力能转换为机械能，驱动负载作直线往复运动或回转运动。
控制元件(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，液压阀可分为村力控制阀、流量控制阀和方向控制阀。压力控制阀又分为益流阀(安全阀)、诚压阀、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、液控单向阀、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。
辅助元件包括油箱、滤油器、油管及管接头、密封圈、快换接头、高压球阀、胶管总成、测压接头、压力表、油位油温计等。
液压油是液压系统中传递能量的工作介质，有各种矿物油、乳化液和合成型液压油等几大类。

液压系统结构
液压系统由信号控制和液压动力两部分组成，信号控制部分用于驱动液压动力部分中的控制阀动作。
液压动力部分采用回路图方式表示，以表明不同功能元件之间的相互关系。液压源含有液压泵、电动机和液压辅助元件;液压控制部分含有各种控制阀，其用于控制工作油液的流量、压力和方向;执行部分含有液压缸或液压马达，其可按实际要求来选择。
在分析和设计实际任务时，一般采用方框图显示设备中实际运行状况。空心箭头表示信号流，而实心箭头则表示能量流。
基本液压回路中的动作顺序一控制元件(二位四通换向阀)的换向和弹簧复位、执行元件(双作用液压缸)的伸出和回缩以及溢流阀的开启和关闭。对 于执行元件和控制元件，演示文稿都是基于相应回路图符号，这也为介绍回路图符号作了准备。
根据系统工作原理，您可对所有回路依次进行编号。如果一个执行元件编号为0，则与其相关的控制元件标识符则为1。如果与执行元件伸出相对应的元件标识符为偶数，则与执行元件回缩相对应的元件标识符则为奇数。不仅应对液压回路进行编号，也应对实际设备进行编号，以便发现系统故障。
DIN ISO1219-2 标准定义了元件的编号组成，其包括下面四个部分，设备编号、回路编号、元件标识符和元件编号。如果整个系统仅有一种设备，则可省略设备编号。
实际中，另一种编号方式就是对液压系统中所有元件进行连续编号，此时，元件编号应该与元件列表中编号相一致。这种方法特别适用于复杂液压控制系统，每个控制回路都与其系统编号相对应。
