REXROTH力士樂葉片泵是轉(zhuǎn)子槽內(nèi)的葉片與泵殼(定子環(huán))相接觸，將吸入的液體由進油側(cè)壓向排油側(cè)的泵。 
REXROTH力士樂葉片泵的管理要點除需防干轉(zhuǎn)和過載、防吸入空氣和吸入真空度過大外，還應(yīng)注意： 
1．REXROTH力士樂泵轉(zhuǎn)向改變，則其吸排方向也改變?nèi)~片泵都有規(guī)定的轉(zhuǎn)向，不允許反。因為轉(zhuǎn)子葉槽有傾斜，葉片有倒角，葉片底部與排油腔通，配油盤上的節(jié)流槽和吸、排口是按既定轉(zhuǎn)向設(shè)計?？赡孓D(zhuǎn)的葉片泵必須專門設(shè)計。 
2．REXROTH力士樂葉片泵裝配 配油盤與定子用定位銷正確定位，葉片、轉(zhuǎn)子、配油盤都不得裝反，定子內(nèi)表面吸入?yún)^(qū)部分zui易磨損，必要時可將其翻轉(zhuǎn)安裝，以使原吸入?yún)^(qū)變?yōu)榕懦鰠^(qū)而繼續(xù)使用。 
3．REXROTH力士樂拆裝 注意工作表面清潔，工作時油液應(yīng)很好過濾。 
4. REXROTH力士樂葉片在葉槽中的間隙太大會使漏泄增加，太小則葉片不能自由伸縮，會導(dǎo)致工作失常。 
5．REXROTH力士樂葉片泵的軸向間隙 對ηv影響很大。 
1)小型泵-0.015～0.03mm 
2)中型泵-0.02～0.045mm 
6．REXROTH力士樂油液的溫度和粘度 一般不宜超過55℃，粘度要求在17～37mm2／s之間。粘度太大則吸油困難；粘度太小則漏泄嚴(yán)重。
