How to maintain the stainless steel centrifugal pump of Lianyu Pump Industry

May 25, 2023

1. When the stainless steel centrifugal pump is used in the cold winter season, after parking, the water plug of the lower part of the pump body should be unscrewed to release the medium. Prevent freezing cracks.

2. The stainless steel centrifugal pump is to be deactivated for a long time. It is necessary to disassemble the pump completely, dry the water, and apply the grease to the rotating parts and joints, and keep them in a safe place.

3. Jog the motor and try to see if the motor is turning correctly.

4. If the stainless steel centrifugal pump is found to have abnormal sound, stop it immediately and check the cause.

5. When the stainless steel centrifugal pump is to be stopped, first close the gate valve and pressure gauge, then stop the motor.

6. Start the motor. When the corrosion-resistant pump is running normally, open the outlet pressure gauge and the inlet vacuum pump. After it shows the appropriate pressure, gradually open the gate valve and check the motor load.

7. Try to control the flow and head of the stainless steel centrifugal pump within the range indicated on the sign to ensure that the stainless steel centrifugal pump runs at the highest efficiency point to obtain the maximum energy saving effect.

8. Unscrew the water-spiding screw plug of the pump body of the stainless steel centrifugal pump and pour the water (or the slurry).

9. Close the gate valve and outlet pressure gauge of the outlet pipe and the imported vacuum gauge.

10. During the operation of stainless steel centrifugal pump, the bearing temperature should not exceed the ambient temperature of 35C, and the maximum temperature should not exceed 80C.

11. The stainless steel centrifugal pump will change the lubricating oil after 100 hours in the first month of work, and change the oil once every 500 hours.

12. Check the corrosion-resistant pump and the pipeline and the joints for looseness. Turn the stainless steel centrifugal pump by hand to see if the stainless steel centrifugal pump is flexible.

13. Add bearing lubrication oil to the bearing body. Observe that the oil level should be at the center line of the oil mark. The lubricating oil should be replaced or replenished in time.

12. Regularly adjust the packing gland to ensure that the drip leakage in the packing chamber is normal (it is better to make a drip leak).

14. Regularly check the wear of the bushings and replace them in time after the wear is large.
