第一，要定期检查零部件是否异常，如有异常，应参照说明书或者其他资料进行检查，如有需要，更换零件。检查排污泵管路及结合处有无松动现象，用手或工具转动，试看排污泵是否灵活。

First, whether the parts should be inspected regularly abnormalities, if there are any exception, should refer to the instruction inspection or other material, if necessary, replacement parts. Check whether there is any loose phenomenon on sewage pump pipe road and the junction, turn by hand or tool, and proved sewage pump is flexible.

第二，尽量控制其流量和扬程在标牌上注明的范围内，以保证其在最高效率点运转，以获得最大的节能效果。

Second, try to control the flow and head, within the scope of the specified on the sign in order to make sure its running at peak efficiency, to achieve maximum energy saving effect.

第三，在运行过程中，轴承温度不能超过环境温度35C，最高温度不得超过80C。

Third, in the process of operation, the bearing temperature cannot exceed environment temperature 35 c, the highest temperature should not exceed 80 c.

第四，如发现有异常声音应立即停车并检查原因。

Fourth, if found to have abnormal sound should immediately stop and check the reason.

第五，排污泵要停止使用时，应先关闭闸阀、压力表，最后停止电机。

Fifth, sewage pump to stop using, should be closed gate valve, pressure gauge, the last stop machine.

第六，自吸排污泵在长时间不用或在寒冬季节使用时，在停车后，要将泵体下部的放水螺塞拧开，将介质放净，以防止冻裂(如是污水请用清水把泵腔清洗干净)。

Sixth, self-priming sewage pump in a long period of time or during the winter season, can be used after parking, a drain at the bottom of the pump body to plug unscrew, put the net medium, in order to prevent the frost crack (thus sewage pump cavity clean with clear water).

第七，潜水排污泵长期不用时，应进行清洗并吊起置于通风干燥处，要注意防冻。若置于水中，每15天至少运转30min(不能干磨)，以检查其功能和适应性。

Seventh, diving sewage pump long-term need not when, should be cleaned and lift in ventilated, dry place, attention should be paid to prevent frostbite. If placed in the water, for at least 30 min every 15 days (not dry grinding), to check its function and adaptation.

第八，电缆每年至少要检查一次，如有破损要及时更换。

Eighth, cable to check at least once a year, if you have failed to timely replacement.
