No matter what product it is, we need maintenance and maintenance during use, so that the life of the sewage pump can be longer, and it can also save us a lot of trouble.
1. Check the sewage pump pipeline and joints for looseness. Turn the sewage pump by hand to see if the sewage pump is flexible.
2. Add bearing lubricating oil into the bearing body, observe that the oil level should be at the center line of the oil mark, and the lubricating oil should be replaced or supplemented in time.
3. Unscrew the water diversion plug of the sewage pump body and pour water diversion (or slurry diversion). Self-priming sewage pump
4. Close the gate valve, outlet pressure gauge and inlet vacuum gauge of the water outlet pipeline.
5. Jog the motor to see if the direction of the motor is correct.
6. Turn on the motor. When the sewage pump is running normally, open the outlet pressure gauge and the inlet vacuum pump and see if they show proper pressure, then gradually open the gate valve, and check the motor load at the same time.
7. Try to control the flow and head of the sewage pump within the range indicated on the sign to ensure that the sewage pump operates at the rate point, so as to obtain a large energy-saving effect.
8. During the operation of the sewage pump, the bearing temperature should not exceed the ambient temperature of 35°C, and the high temperature should not exceed 80°C.
9. If any abnormal sound is found in the sewage pump, stop immediately to check the cause.
10. When the sewage pump is to be stopped, first close the gate valve and pressure gauge, and then stop the motor.
11. During the first month of operation, the middle-opening pump sewage pump should replace the lubricating oil after 100 hours, and then change the oil once every 500 hours.
12. Regularly adjust the packing gland to ensure that the dripping condition in the packing chamber is normal (it is advisable to leak out in drops).
13. Regularly check the wear of the shaft sleeve, and replace it in time after the wear is large.
14. When the sewage pump is used in the cold winter season, after parking, it is necessary to unscrew the drain plug at the lower part of the pump body to drain the medium. Prevent freeze cracking.
5. If the sewage pump is out of use for a long time, it is necessary to disassemble all the pumps, dry the water, and coat the rotating parts and joints with grease.
