柱塞泵是液壓系統(tǒng)的一個重要裝置,。它依靠柱塞在缸體中往復(fù)運動,，使密封工作容腔的容積發(fā)生變化來實現(xiàn)吸油,、壓油,。柱塞泵具有額定壓力高,、結(jié)構(gòu)緊湊,、效率高和流量調(diào)節(jié)方便等優(yōu)點,，被廣泛應(yīng)用于高壓,、大流量和流量需要調(diào)節(jié)的場合,，諸如液壓機,、工程機械和船舶中 徑向柱塞泵可分為閥配流與軸配流兩大類。閥配流徑向柱塞泵存在故障率高,、效率低等缺點,。上70、80年代發(fā)展的軸配流徑向柱塞泵克服了閥配流徑向柱塞泵的不足,。由于徑向泵結(jié)構(gòu)上的特點,，陜定了軸配流徑向柱塞泵比軸向柱塞泵耐沖擊、壽命長,、控制精度高,。變量行程短泵的變量是在變量柱塞和限位柱塞作用下，改變定子的偏心距實現(xiàn)的,，而定于的zui大偏心距為 5—9mm（根據(jù)排量大小不同）,，變量行程很短。且變量機構(gòu)設(shè)計為高壓操縱,，由控制閥進行控制,。故該泵的響應(yīng)速度快。徑向結(jié)構(gòu)設(shè)計克服了如軸向柱塞泵滑靴偏磨的問題,。使其抗沖擊能力大幅度提高。
