柱塞泵是靠柱塞在缸體中作往復(fù)運(yùn)動(dòng)造成密封容積的變化來實(shí)現(xiàn)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(diǎn)。首先，構(gòu)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(shí)現(xiàn)變量；第三，柱塞泵中的主要零件均受壓應(yīng)力作用，材料強(qiáng)度性能可得到充分利用。由于 柱塞泵壓力高，結(jié)構(gòu)緊湊，效率高，流量調(diào)節(jié)方便，故在需要高壓、大流量、大功率的系統(tǒng)中和流量需要調(diào)節(jié)的場(chǎng)合，如龍門刨床、拉床、液壓機(jī)、工程機(jī)械、礦山冶金機(jī)械、船舶上得到廣泛的應(yīng)用。柱塞泵按柱 塞的排列和運(yùn)動(dòng)方向不同，可分為徑向柱塞泵和軸向柱塞泵兩大類。
