How to maintain and maintain deep well pumps?

 

Jog the motor to see if the motor turns correctly.

 

Add bearing lubricating engine oil to the bearing body. The oil level of the pipeline pump should be at the center line of the oil standard. The lubricating oil should be replaced or supplemented in time.

 

Unscrew the water diversion plug of the pump body of the deep well pump, and inject the water diversion (or slurry).

 

Close the gate valve, outlet pressure gauge and inlet vacuum gauge of the outlet pipe.

 

Check the deep well pump and pipelines and joints for looseness. Turn the deep well pump by hand to see if the deep well pump is flexible.

 

Start the motor. When the deep well pump is running normally, turn on the outlet pressure gauge and inlet vacuum pump. After the proper pressure is displayed, gradually open the gate valve and check the motor load.

 

Try to control the flow and head of the deep well pump within the range indicated on the label to ensure that the deep well pump operates at the highest efficiency point to obtain the maximum energy saving effect.

 

During the operation of the deep well pump, the bearing temperature cannot exceed 35C, and the maximum temperature cannot exceed 80C.

 

If abnormal sound of deep well pump is found, stop immediately and check the cause.

 

When the deep well pump is to be stopped, first close the gate valve and pressure gauge, then stop the motor.

 

In the first month of operation, the deep well pump will change the lubricating oil after 100 hours, and the oil will be changed once every 500 hours after the screw pump.

 

Regularly adjust the packing gland to ensure that the drip condition in the packing chamber is normal (it is better to make the drip out).
Regularly check the wear of the shaft sleeve, and replace it in time after the wear is large.

 

The deep-well pump is out of service for a long time. It is necessary to disassemble the pump completely, wipe off the water, apply grease to the rotating parts and joints, and store them properly.

 

When the deep well pump is used in the cold winter season, after stopping, the water drain plug at the bottom of the pump body needs to be unscrewed to release the medium. Prevent frost cracking.
