柱塞泵是靠柱塞在缸體中作往復運動造成密封容積的變化來實現吸油與壓油的液壓泵，與齒輪泵和葉  片泵相比，這種泵有許多優(yōu)點。首先，構成密封容積的零件為圓柱形的柱塞和缸孔，加工方便，可得到較  高的配合精度，密封性能好，在高壓工作仍有較高的容積效率；第二，只需改變柱塞的工作行程就能改變  流量，易于實現變量；第三，柱塞泵中的主要零件均受壓應力作用，材料強度性能可得到充分利用。由于  柱塞泵壓力高，結構緊湊，效率高，流量調節(jié)方便，故在需要高壓、大流量、大功率的系統中和流量需要調節(jié)的場合，如龍門刨床、拉床、液壓機、工程機械、礦山冶金機械、船舶上得到廣泛的應用。柱塞泵按柱  塞的排列和運動方向不同，可分為徑向柱塞泵和軸向柱塞泵兩大類。
