Many customers know to choose the fluoroplastic centrifugal pump that best meets production requirements in engineering production, but they often overlook the daily maintenance and upkeep of the equipment after use. Proper maintenance of the equipment after operation can greatly reduce production costs. Next, Little Giant Pump Industry will take you to understand some precautions for maintaining fluoroplastic centrifugal pumps.

1. Check for any looseness in the piping and joints of the fluoroplastic centrifugal pump. Rotate the fluoroplastic centrifugal pump by hand to see if it is flexible.

2. Add bearing lubricating oil into the bearing body, and observe that the oil level is at the middle line of the oil gauge. The lubricating oil should be replaced or replenished in a timely manner.

3. Unscrew the water inlet plug of the fluoroplastic centrifugal pump body and inject water or slurry.

4. Close the gate valve, outlet pressure gauge, and inlet vacuum gauge of the water outlet pipeline.

5. Tap the motor and try to see if the motor direction is correct.

6. Start the motor, when the fluoroplastic centrifugal pump is running normally, open the outlet pressure gauge and the inlet vacuum pump to see if they display appropriate pressure, gradually open the gate valve, and check the motor load at the same time.

7. Try to control the flow rate and head of the fluoroplastic centrifugal pump within the range indicated on the label as much as possible to ensure that the fluoroplastic centrifugal pump operates at the efficiency point, in order to achieve significant energy-saving effects.

8. During the operation of the fluoroplastic centrifugal pump, the bearing temperature should not exceed 35C of the ambient temperature, and the high temperature should not exceed 80C.

9. If any abnormal sound is found in the fluoroplastic centrifugal pump, it should be stopped immediately to check the cause.

10. When the fluoroplastic centrifugal pump needs to be stopped, first close the gate valve and pressure gauge, and then stop the motor.

11. The fluoroplastic centrifugal pump should change the lubricating oil after 100 hours of operation within one month, and then change the oil every 500 hours thereafter.

12. Regularly adjust the packing gland to ensure that the dripping situation inside the packing chamber is normal, preferably in the form of droplets.

13. Regularly check the wear of the shaft sleeve, and replace it promptly if there is significant wear.

14. When using a fluoroplastic centrifugal pump in the cold winter season, after parking, it is necessary to unscrew the drain plug at the bottom of the pump body to drain the medium completely. Prevent frost cracking.

15. If the fluoroplastic centrifugal pump is not used for a long time, the pump should be completely disassembled, wiped dry, and the rotating parts and joints should be coated with grease and properly protected.
