Self priming sewage pump daily maintenance and maintenance guide


The daily maintenance and maintenance of the self priming sewage pump is crucial, and the following are the relevant guidelines:

Preparation before maintenance:

Before maintenance, first disconnect the power supply to ensure the safety of the equipment.

Install shields or nets to prevent accidental contact or injury.

Clean-up work:

The self priming sewage pump may accumulate dirt and debris during the working process. Therefore, regular cleaning is necessary.

Close the inlet and outlet water valve, remove the inlet pipe and pump cover, clean the fin, impeller and other easily blocked parts, and clean with water or appropriate cleaning agent.

Check and replace wearing parts:

The seals, bearings, mechanical seals and other components in the self-priming sewage pump are vulnerable parts, and their wear needs to be checked regularly.

Mechanical seals, in particular, usually need to be replaced every six months, or promptly when a leak is found.

The temperature of the bearing should be controlled within a reasonable range to avoid damage caused by overheating.

Lubrication and fastening:

Add the appropriate amount of lubricating oil to bearings and other moving parts as needed to ensure their normal operation.

Check and tighten all bolts, nuts and other fasteners to prevent failure caused by loosening.

Electrical part inspection:

Check the integrity of the cable and replace it in time if it is damaged.

Use tools such as a screwdriver or a listening rod to carefully listen to the running sound of the motor and determine whether there is abnormal vibration or insufficient bearing oil.

Test and adjustment:

After completing the maintenance, restart the self-priming sewage pump and observe its operation to ensure that everything is normal.

Adjust the tightness of the connection between the suction pipe and the discharge pipe as required to ensure their safe use.

Record and feedback:

Make a record of each maintenance work, including maintenance time, content, replacement parts, etc., for future reference.

If any problems or abnormalities are found in the maintenance process, timely feedback to the relevant personnel for timely treatment.

Through the above daily maintenance and maintenance work, you can ensure the normal operation of the self-priming sewage pump, extend its service life, and improve the efficiency of sewage treatment. Please note that these steps are only general guidelines, and specific maintenance work may vary depending on the device model, use environment, and use conditions. Therefore, when carrying out maintenance, it is best to refer to the instructions of the equipment or consult the advice of professionals.
