1、回油管应畅通，以防止回油管阻塞引起柱塞泵的故障 当柱塞泵中的液位过低时，会引起溢流阀损坏或柱塞泵中液压油压力过高，造成回油管堵塞这时，应及时更换回油管和活塞，以保证柱塞泵正常工作当柱塞泵在连续工作时，应注意防止柱塞泵内部零件过度磨损甚至损坏。

使用环境应注意防潮、防尘和防止阳光直射在炎热季节应注意防暑降温工作同时，使用工具时要注意保持卫生此外，一些设备、工具和附件在工作中应定期清洗或者更换润滑脂 2、和油泵不同，柱塞泵的压力大小由调节系统压力来调节。

如果压气机的压力过高，则需增加供油量来调节，这样也可以降低柱塞的压缩比；如果压力过低，则需要降低压气机的压气量来改善，这也可以提高泵流量因为，当柱塞在进油口，压气机就必须启动，才能完成进油；而当柱塞在排气口时，压气机就不需要启动，而是继续工作。

如果进不了油就会导致气缸壁腐蚀、气缸内漏油等问题因此必须通过减少进油口压力这种办法来减少柱塞泵的压力所以，为了减少进油口压力，需要降低柱塞与进油口之间的压差通常情况下，泵流量越大时压力越大；反之压力越小。

对于较大型号和流量较小的泵，需要降低进油门压力来减少进流量；而对于较小型号，或者较小流量较大而压力相对较高时，需要增加进油道压力来缓解泵流量不足问题 90-R-130-KA-5-BC-80-S-3-F1-F-04-GBA-35-35-24 90R130KA5BC80S3F1F04GBA353524 90R130-KA-5-BC-80-S-3-F1-H-03-GBA-40-40-30 90R130KA5BC80S3F1H03GBA404030 90-R-130-KA-5-BC-80-S-3-F1-H-03-GBA-40-40-30 90R130KA5BC80S3F1H03GBA404030 90R130-KA-5-BC-80-S-3-F1-H-03-GBA-42-42-24 90R130KA5BC80S3F1H03GBA424224 90-R-130-KA-5-BC-80-S-3-F1-H-03-GBA-42-42-24 90R130KA5BC80S3F1H03GBA424224 90R130-KA-5-BC-80-S-4-C8-F-03-GBA-42-42-24 90R130KA5BC80S4C8F03GBA424224 90-R-130-KA-5-BC-80-S-4-C8-F-03-GBA-42-42-24 90R130KA5BC80S4C8F03GBA424224 90R130-KA-5-BC-80-S-4-C8-H-03-GBA-26-26-24 90R130KA5BC80S4C8H03GBA262624 90-R-130-KA-5-BC-80-S-4-C8-H-03-GBA-26-26-24 90R130KA5BC80S4C8H03GBA262624 90R130-KA-5-BC-80-S-4-C8-H-03-GBA-35-14-30 90R130KA5BC80S4C8H03GBA351430 90-R-130-KA-5-BC-80-S-4-C8-H-03-GBA-35-14-30 90R130KA5BC80S4C8H03GBA351430 90R130-KA-5-BC-80-S-4-C8-H-03-GBA-35-35-24 90R130KA5BC80S4C8H03GBA353524 90-R-130-KA-5-BC-80-S-4-C8-H-03-GBA-35-35-24 90R130KA5BC80S4C8H03GBA353524 90R130-KA-5-BC-80-S-4-C8-H-03-GBA-42-42-24 90R130KA5BC80S4C8H03GBA424224 90-R-130-KA-5-BC-80-S-4-C8-H-03-GBA-42-42-24 90R130KA5BC80S4C8H03GBA424224 90R130-KA-5-BC-80-S-4-C8-H-04-GBA-42-42-24 90R130KA5BC80S4C8H04GBA424224 90-R-130-KA-5-BC-80-S-4-C8-H-04-GBA-42-42-24 90R130KA5BC80S4C8H04GBA424224 90R130-KA-5-BC-80-S-4-F1-F-03-GBA-26-26-24 90R130KA5BC80S4F1F03GBA262624 90-R-130-KA-5-BC-80-S-4-F1-F-03-GBA-26-26-24 90R130KA5BC80S4F1F03GBA262624 90R130-KA-5-BC-80-S-4-F1-H-05-GBA-42-42-24 90R130KA5BC80S4F1H05GBA424224 90-R-130-KA-5-BC-80-S-4-F1-H-05-GBA-42-42-24 90R130KA5BC80S4F1H05GBA424224 90R130-KA-5-BC-80-S-4-F1-H-06-GBA-29-29-24 90R130KA5BC80S4F1H06GBA292924 90-R-130-KA-5-BC-80-S-4-F1-H-06-GBA-29-29-24 90R130KA5BC80S4F1H06GBA292924 90-R-130-KA-5-CD-80-D-3-C8-L-03-GBA-40-40-22 90R130KA5CD80D3C8L03GBA404022 90R130-KA-5-CD-80-D-3-F1-L-03-GBA-35-35-24 90R130KA5CD80D3F1L03GBA353524 90-R-130-KA-5-CD-80-D-3-F1-L-03-GBA-35-35-24 90R130KA5CD80D3F1L03GBA353524 90R130-KA-5-CD-80-D-4-C8-L-05-GBA-35-35-24-F076 90R130KA5CD80D4C8L05GBA353524F076 90-R-130-KA-5-CD-80-D-4-C8-L-05-GBA-35-35-24-F076 90R130KA5CD80D4C8L05GBA353524F076 90R130-KA-5-CD-80-D-4-F1-L-03-GBA-42-42-24 90R130KA5CD80D4F1L03GBA424224 90-R-130-KA-5-NN-80-S-4-C8-H-03-GBA-38-38-24 90R130KA5NN80S4C8H03GBA383824 。
