力士樂柱塞泵是液壓系統(tǒng)的動力元件，是靠發(fā)動機或電動機驅動，從液壓油箱中吸入油液，形成壓力油排出，送到執(zhí)行元件的一種元件。液壓泵按結構分為齒輪泵、柱塞泵、葉片泵和螺桿泵

為液壓傳動提供加壓液體的一種液壓元件，是泵的一種。它的功能是把動力機（如電動機和內燃機等）的機械能轉換成液體的壓力能。影響液壓泵的使用壽命因素很多，除了泵自身設計、制造因素外和一些與泵使用相關元（如聯(lián)軸器、濾油器等）的選用、試車運行過程中的操作等也有關。
液壓泵的工作原理是運動帶來泵腔容積的變化，從而壓縮流體使流體具有壓力能。
必須具備的條件就是泵腔有密封容積變化。
常用液壓泵的種類：
1、按流量是否可調節(jié)可分為：變量泵和定量泵。
輸出流量可以根據(jù)需要來調節(jié)的稱為變量泵，流量不能調節(jié)的稱為定量泵。
2、按液壓系統(tǒng)中常用的泵結構分為：齒輪泵、葉片泵和柱塞泵3種。
齒輪泵：體積較小，結構較簡單，對油的清潔度要求不嚴，價格較便宜；但泵軸受不平衡力，磨損嚴重，泄漏較大。
葉片泵：分為雙作用葉片泵和單作用葉片泵。這種泵流量均勻、運轉平穩(wěn)、噪音小、作壓力和容積效率比齒輪泵高、結構比齒輪泵復雜。
  液壓泵內部結構圖
柱塞泵：容積效率高、泄漏小、可在高壓下工作、大多用於大功率液壓系統(tǒng)；但結構復雜，材料和加工精度要求高、價格貴、對油的清潔度要求高。
一般在齒輪泵和葉片泵不能滿足要求時才用柱塞泵。還有一些其他形式的液壓泵，如螺桿泵等，但應用不如上述3種普遍。
