柱塞泵是靠柱塞在缸體中作往復(fù)運動造成密封容積的變化來實現(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。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(yīng)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。
