1、水泵不吸水或不排水。造成这种故障多数是由于底阀卡死、滤水部分淤塞，吸水高度太高或吸水管漏气等。应逐一进行检查，分别采取修理底阀、xx淤塞物、纠正转向等进行处理。 2、管道漏水或漏气。多是由于螺帽没拧紧。如果渗漏不严重，可以在渗漏处涂抹水泥浆、湿泥或软肥皂；如果接头处漏水，可用扳手拧紧螺帽。严重漏水、漏气时，必须重新拆装。 3、水泵剧烈震动。可能是电动转子不平衡或 联轴器结合不良。有时轴承磨损、弯曲，转动部位零件松弛、破裂，管路支架不牢也会引起震动。应分别调整、加固、检查或更换。 4、叶轮打坏。损坏不大时，可以进行修补。损坏严重时应当更换或镀上硬质合金。xx损坏的，应拆下叶轮，送维修厂修理。 5、泵轴弯曲。多是由于受冲击负荷，皮带拉得过紧、安装不正确等造成的。如果弯的不严重，可用手动螺杆器进行矫正，但用力不可过猛，以防xx折断。

译文：
1, water pump does not absorb water or drainage. Most of causing such failure is due to the end of valve stuck, the treatment part of the blockage, suction height is too high or the suction pipe leaks, etc.. Should be checked one by one, were taken to the end of valve repair, clear blockage and correct the steering and other processing. 2, pipe leakage or air leakage. No more than nuts tightened due. If the leak is not serious, you can smear grout leaks, Shini or soft soap; If the joints leak, can wrench to tighten the nut. Serious air and water leakage must be re-disassembly. 3, severe vibration pump. May be the combination of electrical coupling rotor imbalance or bad. Sometimes bearing wear, bending, turning loose of parts and components, broken pipe can cause vibration support is not strong. Should be adjusted to, reinforcement, inspection or replacement. 4, impeller bash. Little damage, they can be repaired. Serious damage should be replaced or coated cemented carbide. Completely damaged, remove the impeller should be sent to the repair station repairs. Five, shaft bending. Mostly due to the impact load, belt pulled too tight, not installed correctly and so caused. If the bending is not serious, can be corrected manually screw device, but not excessive force to prevent completely broken.
