5、輸出壓力異常
Rexroth泵的輸出壓力是由負載決定的，與輸入轉(zhuǎn)矩近似成正比。輸出壓力異常有兩種故障。
(1)輸出壓力過低
當(dāng)Rexroth泵在自吸狀態(tài)下，若進油管路漏氣或系統(tǒng)中液壓缸、單向閥、換向閥等有較大的泄漏，均會使壓力升不上去。這需要找出漏氣處，緊固、更換密封件，即可提高壓力。溢流閥有故障或調(diào)整壓力低，系統(tǒng)壓力也上不去，應(yīng)重新調(diào)整壓力或檢修溢流閥。如果Rexroth液壓泵的缸體與配流盤產(chǎn)生偏差造成大量泄漏，嚴重時，缸體可能破裂，則應(yīng)重新研磨配合面或更換Rexroth液壓泵。
(2)輸出壓力過高
若回路負載持續(xù)上升，泵的壓力也持續(xù)上升，當(dāng)屬正常。若負載一定，泵的壓力超過負載所需壓力值，則應(yīng)檢查泵以外的液壓元件，如方向閥、壓力閥、傳動裝置和回油管道。若最大壓力過高，應(yīng)調(diào)整溢流閥。
6、振動和噪聲
振動和噪聲是同時出現(xiàn)的。它們不僅對機器的操作者造成危害，也對環(huán)境造成污染。
(1)機械振動和噪聲
如泵軸和電機軸不同心或頂死，旋轉(zhuǎn)軸的軸承、聯(lián)軸節(jié)損傷，彈性墊破損和裝配螺栓松動均會產(chǎn)生噪聲。對于高速運轉(zhuǎn)或傳輸大能量的泵，要定期檢查，記錄各部件的振幅、頻率和噪聲。如泵的轉(zhuǎn)動頻率與壓力閥的固有頻率相同時，將會引起共振，可改變泵的轉(zhuǎn)速以消除共振。
(2)管道內(nèi)液流產(chǎn)生的噪聲
進油管道太細、進油濾油器通流能力過小或堵塞、進油管吸入空氣、油液豁度過高、油面過低吸油不足和高壓管道中產(chǎn)生液擊等，均會產(chǎn)生噪聲。因此，必須正確設(shè)計油箱，正確選擇濾油器、油管和方向閥。
