?液壓系統是工程機械的重要組成部分，液壓系統由各種不同的液壓元件和管路組成它們的功能是傳遞和控制機械動作的過程系統中的運動是由液壓元件的動作之間的轉換過程構成的油液從油箱到油管和油泵的油路在一定范圍內有工作壓力，液壓元件通過一定的流量實現動作。
液壓件通過其傳動元件在一定的行程范圍內實現動力傳遞、壓力傳遞和溫度控制的過程液壓元件通過傳遞力或能量來實現液壓的傳遞動作液壓件是液壓系統的核心部分，它直接關系到液壓系統的可靠性、耐久性和效率因此，對液壓系統的設計和制造具有非常重要的意義和作用。
對液壓系統配件的選擇可靠、耐用、低成本的液壓系統配件不僅要符合質量標準，而且還要具有良好的耐久性和耐腐蝕性以及能滿足液壓系統應用的要求，符合產品設計要求或技術規范的規定等性能要求具有良好的機械性能，如：承載能力強、壓力大、沖擊小、耐腐蝕、耐磨性好等；耐熱性好；抗污染性好；耐腐蝕性好。
有一定的耐磨性差液壓配件不僅可以保證系統運行的正常穩定性和可靠性還要能承受外來壓力和沖擊，使用壽命長等特點目前液壓配件主要有以下幾大類：液壓缸、閥體、油管、液壓接頭、油缸等；還有一個最重要和經常被忽視—油泵和油箱等配件也具有同樣獨特的性能特點和作用，也就說需要有一套系統結構才能發揮出作用。
因此必須要重視其性能特點與作用接下來由金牛液壓為您介紹：液壓件是一種運動元件，液壓元件及其之間配合運動實現各種功能的裝置，它以一定形狀、尺寸或系統工作狀態的運動來傳遞機械動力或能量的元件液壓系統主要由執行部件和傳動部件組成：液壓部件由油泵（氣缸）、閥體、油箱、油通道、柱塞泵等組成。
液壓部件是液壓系統的核心部件，由多個部件組成的復雜系統稱為液壓系統 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
