德國(guó)Rexroth柱塞泵力士樂(lè)柱塞泵分為軸向柱塞泵和徑向柱塞泵兩種代表性的結(jié)構(gòu)形式；由于徑向柱塞泵屬于一種新型的技術(shù)含量比較高的高效泵，隨著國(guó)產(chǎn)化的不斷加快，徑向柱塞泵必然會(huì)成為柱塞泵應(yīng)用領(lǐng)域的重要組成部分軸向柱塞泵是利用與傳動(dòng)軸平行的柱塞在柱塞孔內(nèi)往復(fù)運(yùn)動(dòng)所產(chǎn)生的容積變化來(lái)進(jìn)行工作的。由于柱塞和柱塞孔都是圓形零件，加工時(shí)可以達(dá)到很高的精度配合，因此具有容積效率高，運(yùn)轉(zhuǎn)平穩(wěn)，流量均勻性好，噪聲低，工作壓力高等優(yōu)點(diǎn)，但對(duì)液壓油的污染較敏感，結(jié)構(gòu)較復(fù)雜，造價(jià)較高。
