泵是輸送流體或使流體增壓的機(jī)械。它將原動(dòng)機(jī)的機(jī)械能或其他外部能量傳送給液體，使液體能量增加。力士樂泵主要用來輸送水、油、酸堿液、乳化液、懸乳液和液態(tài)金屬等液體，也可輸送液、氣混合物及含懸浮固體物的液體。力士樂泵通�？砂垂ぷ髟�理分為容積式力士樂泵、動(dòng)力式力士樂泵和其他類型力士樂泵三類。除按工作原理分類外，還可按其他方法分類和命名。如，按驅(qū)動(dòng)方法可分為電動(dòng)力士樂泵和水輪力士樂泵等；按結(jié)構(gòu)可分為單級(jí)力士樂泵和多級(jí)力士樂泵；按用途可分為鍋爐給水力士樂泵和計(jì)量力士樂泵等；按輸送液體的性質(zhì)可分為水力士樂泵、油力士樂泵和泥漿力士樂泵等。按照有無軸結(jié)構(gòu)，可分直線力士樂泵，和傳統(tǒng)力士樂泵。

PR4-3X/2,00-700RA01M02徑向柱塞泵

裝配

泵為閥控自吸式徑向柱塞泵，排量固定。

泵基本上由殼體 (1)、偏心軸 (2) 以及吸油閥 (4)、壓力閥 (5和柱塞 (6) 等泵元件 (3)組成。

吸油和排油過程

柱塞 (6) 相對(duì)于偏心軸 (2)沿徑向排列。柱塞 (6) 由液壓缸 (7) 導(dǎo)向并在彈簧 (8) 作用下貼緊偏心構(gòu)件 (2)。在柱塞 (6)向下運(yùn)動(dòng)的過程中，液壓缸 (7) 中工作腔體 (9) 的尺寸將加大。產(chǎn)生的負(fù)壓力用于自密封邊提升吸油閥板 (4.1) 。這樣可以打開吸油腔體 (10) 到工作腔體 (9)的連接。工作腔體中充滿液壓油。在柱塞 (6)向上運(yùn)動(dòng)的過程中，吸油閥將關(guān)閉，壓力閥 (5) 將開啟。液壓油現(xiàn)可經(jīng)壓力油口 (P)流向系統(tǒng)。
