1、泵缸内有无异物或破碎物 将螺母旋入或拔出螺母与泵上的螺钉不得拧得过紧或拧得过松螺母与泵缸的间隙应为0.1-0.20mm,以防发生飞溅和磨损影响泵效率或导致泵工作不稳定将泵入液体放尽注意观察压力和流量，并用软管向管道内加注液压油。
将泵叶插入或抽出叶片孔时，必须将叶轮放在孔内或支架上保持泵叶在工作中在使用中应随时观察液面是否下降、溢流槽是否堵塞、液面高度是否与作业高度一致等情况 2.定期检查管道接口是否堵塞 要经常清理管路接口内的杂质。
应定期检查管路接头内的密封面是否被破坏要经常检查连接接头内的密封垫是否被磨损如发现密封垫磨损、泄漏量过大，必须及时更换要经常注意管路接头密封圈（端面）是否有裂纹，如有裂纹或龟裂，应及时处理如果胶圈开裂或裂纹较深，必须及时更换。
应经常检查液压管路接头密封垫安装是否到位，松动处是否正确涂以黄油或煤油保持良好润滑状态；检查液压管路接头密封垫处密封效果是否良好；检查各部位螺钉螺栓连接是否牢固；检查油泵是否运转正常；检查各液压阀、接头内阀塞是否漏油后及时加以修理或更换；检查接头密封是否严密、密封是否完好、密封面是否有损坏或脱胶现象等；检查各部位螺栓密封间隙是否符合要求；各部位螺钉是否松动等；在使用过程中要注意防止设备意外移动而造成的伤害；定期检查液压管路接头密封圈以及液压油中油量及油质和泵送介质质量、压力及其管道内壁清理液面等工作情况。
