Cleaning and maintenance methods for centrifugal pump equipment

  The centrifugal pump is a rear opening type, and the suction and discharge pipelines do not need to be disassembled when removing the pump cover and impeller. The suspension is equipped with two ball bearings, lubricated with machine oil or grease. The pump is directly driven by an electric motor through an elastic coupling.

  The vortex chamber, feet, inlet flange, and outlet flange are cast as a whole, and the structure of the equipment is calibrated to be simple. First, ensure that the pump is used within the rated range and cannot operate without load. Secondly, pay attention to avoiding cavitation and steam binding phenomena, strengthen inspections, and replace worn sealing components in a timely manner.

  Check for any looseness in the equipment pipelines and joints. Rotate by hand to see if the device is flexible.

  Add bearing lubricating oil into the bearing body and observe that the oil level should be at the centerline of the oil mark. The lubricating oil should be replaced or replenished in a timely manner.

  Unscrew the water inlet plug of the equipment pump body and inject water.

  Close the gate valve and outlet pressure gauge of the water outlet pipeline.

  Inch the motor and test the Wuxi welded pipe to see if the motor direction is correct.

  Start the motor, and when the equipment is running normally, open the outlet pressure gauge to see that it shows the appropriate pressure. Gradually open the gate valve and check the motor load condition.

  Try to control the flow and head of the equipment within the range indicated on the label to ensure high-performance operation and achieve energy-saving effects.

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

  If the equipment needs to be stopped, first close the gate valve and pressure gauge, and then stop the motor.

  Regularly adjust the packing gland to ensure normal dripping in the packing chamber.

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

  When the equipment is used 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.
