What Should Be Noted for Daily Maintenance of Sewage Pumps?

Common problems with sewage pump maintenance include: motor failure, leakage caused by seal failure, impeller blockage or wear, bearing damage, and loose pipeline connections. These issues can affect the efficiency and lifespan of the pump, and even lead to shutdown. Regular inspection and maintenance, timely replacement of damaged parts, and ensuring correct installation and operation can effectively extend the service life of sewage pumps.

The following are common problems encountered during the maintenance of sewage pumps:

Q1.What does the daily maintenance of sewage pumps include?

A1:Regularly inspect cables, motors, shaft seals, impellers, pump bodies, clean dirt, lubricate bearings, test electrical systems, etc.

Q2.How to determine if the sewage pump needs maintenance?

A2:When there is a significant decrease in flow or head, increased operating noise, intensified vibration, water leakage, and leakage, maintenance is required.

Q3.How to deal with the wear of the impeller of the sewage pump?

A3:Mild wear can be polished and repaired, while severe wear requires replacement of the impeller.

Q4.How to maintain the bearings of the sewage pump?

A4:Regularly add or replace lubricating grease, check the wear of bearings, and replace bearings if necessary.

Q5.How to maintain the mechanical seal of the sewage pump?

A5:Regularly check the wear of mechanical seals, replace seals if necessary, and ensure that the sealing surface is clean.

Q6.How to maintain the motor of the sewage pump?

A6:Regularly check the insulation resistance of the motor winding, clean the dust inside the motor, and check if the cable connections are firm.

Q7.How to prevent corrosion of sewage pump pipelines?

A7:Choose pipes made of corrosion-resistant materials, regularly inspect the corrosion of the pipes, and replace severely corroded parts if necessary.

Q8.How to choose lubricating oil for sewage pumps?

A8:Select the appropriate lubricating oil according to the pump's instructions to ensure the quality and cleanliness of the lubricating oil.

Q9.How to check

A9:Determine the maintenance cycle based on the usage of the pump and the manufacturer's recommendations, generally ranging from six months to one year.
