The horizontal multistage centrifugal pump design has a service life of 20 years, and the actual service life is related to the maintenance of the horizontal multistage centrifugal pump. Huali Pumps introduces the correct maintenance method for everyone:
1. Check for looseness at each joint of the horizontal multistage centrifugal pump and the pipeline. Turn the pump by hand to see if the pump is flexible, then try the motor steering.
2. Add bearing lubrication oil to the suspension and observe that the oil level should be between the two engraved lines of the oil mark.
3. Unscrew the water plug screw of the pump body and pump water.
4. Close the gate valve and outlet pressure gauge of the outlet pipe and the imported vacuum gauge.
5. Start the motor. When the pump is running normally, work the outlet pressure gauge and the imported vacuum gauge. After displaying the appropriate pressure, gradually open the gate valve and check the motor load.
6. Try to control the flow and head of the pump within the range indicated on the horizontal multistage centrifugal pump sign to ensure that the pump runs for a long time near the high efficiency point in order to obtain the maximum energy saving effect.
7. During the operation of the horizontal multistage centrifugal pump, the temperature rise of the bearing does not exceed the ambient temperature of 35 degrees, and the maximum temperature does not exceed 80 degrees.
8. If the horizontal multistage centrifugal pump is found to have abnormal sound, it should be stopped immediately to check the cause.
9. When the horizontal multistage centrifugal pump is to be stopped, first close the gate valve and pressure gauge, then stop the motor.
10. The horizontal multistage centrifugal pump replaces the lubricating oil in 100 hours during the first month of operation. Change oil every 500 hours later.
11. Regularly adjust the packing gland to ensure that the drip in the packing chamber is normal.
12. When the horizontal multistage 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 water to prevent freezing cracking.
13. The horizontal multi-stage centrifugal pump should be deactivated for a long time. All the pumps must be disassembled, the water should be wiped dry, and the rotating parts and joints should be coated with grease and properly stored.
