Maintenance and upkeep methods for stainless steel water pumps:
(1) Check the stainless steel water pump, pipelines, and joints for looseness. Rotate the stainless steel water pump by hand to see if it is flexible.
(2) Add bearing lubricating oil to the bearing body, observe that the oil level should be at the centerline of the oil mark, and 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) Inch the motor to see if the motor is turning correctly.
(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 the appropriate pressure is displayed, gradually open the gate valve and check the motor load condition.
(7) Try to control the flow 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 a high efficiency point and achieves energy-saving effects.
(8) During the operation of stainless steel water pumps, the bearing temperature should not exceed the ambient temperature of 35C, and the maximum temperature should not exceed 80C.
(9) If any abnormal sound is found in the stainless steel water pump, it should be immediately stopped to check the cause.
(10) When the stainless steel water pump needs to be stopped, first close the gate valve and pressure gauge, and then stop the motor.
(11) During the first month of operation, the stainless steel water pump undergoes a 100 hour oil change, followed by an oil change every 500 hours thereafter.
(12) Regularly adjust the packing gland to ensure normal leakage in the packing chamber (preferably in droplets).
(13) Regularly check the wear of the shaft sleeve, and replace it in a timely manner after significant wear.
(14) When using stainless steel water pumps in cold winter seasons, 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 has been out of service for a long time. It is necessary to disassemble all the pumps, dry the water, apply grease to the rotating parts and joints, and store them properly.
