液压系统是工程机械的重要组成部分，液压系统由各种不同的液压元件和管路组成它们的功能是传递和控制机械动作的过程系统中的运动是由液压元件的动作之间的转换过程构成的油液从油箱到油管和油泵的油路在一定范围内有工作压力，液压元件通过一定的流量实现动作。
液压件通过其传动元件在一定的行程范围内实现动力传递、压力传递和温度控制的过程液压元件通过传递力或能量来实现液压的传递动作液压件是液压系统的核心部分，它直接关系到液压系统的可靠性、耐久性和效率因此，对液压系统的设计和制造具有非常重要的意义和作用。
对液压系统配件的选择可靠、耐用、低成本的液压系统配件不仅要符合质量标准，而且还要具有良好的耐久性和耐腐蚀性以及能满足液压系统应用的要求，符合产品设计要求或技术规范的规定等性能要求具有良好的机械性能，如：承载能力强、压力大、冲击小、耐腐蚀、耐磨性好等；耐热性好；抗污染性好；耐腐蚀性好。
有一定的耐磨性差液压配件不仅可以保证系统运行的正常稳定性和可靠性还要能承受外来压力和冲击，使用寿命长等特点目前液压配件主要有以下几大类：液压缸、阀体、油管、液压接头、油缸等；还有一个最重要和经常被忽视—油泵和油箱等配件也具有同样独特的性能特点和作用，也就说需要有一套系统结构才能发挥出作用。
因此必须要重视其性能特点与作用接下来由金牛液压为您介绍：液压件是一种运动元件，液压元件及其之间配合运动实现各种功能的装置，它以一定形状、尺寸或系统工作状态的运动来传递机械动力或能量的元件液压系统主要由执行部件和传动部件组成：液压部件由油泵（气缸）、阀体、油箱、油通道、柱塞泵等组成。
液压部件是液压系统的核心部件，由多个部件组成的复杂系统称为液压系统 90R075-KA-5-NN-60-S-3-S1-E-03-GBA-42-42-24 90R075KA5NN60S3S1E03GBA424224 90-R-075-KA-5-NN-60-S-3-S1-E-03-GBA-42-42-24 90R075KA5NN60S3S1E03GBA424224
