Maintenance and upkeep methods for stainless steel water pumps:
Firstly, in daily use,
Ensure that the operating voltage of the submersible pump reaches the rated voltage. Ensure that there is no phase loss during the operation of the motor and that the water pump has sufficient water supply.
(1) Check for any looseness in the stainless steel water pump, pipelines, and joints. Rotate the stainless steel water pump by hand and see if it is flexible.
(2) 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.
(3) Unscrew the water inlet plug of the stainless steel water 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) Jog the motor and check if the direction of rotation is correct.
(6) Start the motor, and when the stainless steel water pump is running normally, open the outlet pressure gauge and the inlet vacuum pump. After observing the appropriate pressure displayed, gradually open the gate valve and check the motor load condition.
(7) Try to control the flow rate and head of the stainless steel water pump within the range indicated on the label to ensure that the stainless steel water pump operates at the highest efficiency point, in order to achieve the maximum energy-saving effect.
(8) During the operation of stainless steel water pumps, the bearing temperature should not exceed the ambient temperature of 35 ℃, and the maximum temperature should not exceed 80 ℃.
(9) If any abnormal sound is found in the stainless steel water pump, it should be stopped immediately to check the cause.
(10) When the stainless steel water pump needs to be stopped from use, first close the gate valve and pressure gauge, and then stop the motor.
(11) Within the first month of operation, the stainless steel water pump should replace the lubricating oil after 100 hours, and then every 500 hours.
(12) Regularly adjust the packing gland to ensure normal dripping inside the packing chamber (preferably in drops).
(13) Regularly check the wear of the shaft sleeve, and replace it promptly if there is significant wear.
(14) When the stainless steel water pump 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.
(15) The stainless steel water pump needs to be dismantled and wiped dry for long-term use. The rotating parts and joints should be coated with grease and properly stored.
