1) Check whether there is any looseness in the pipes and joints of the stainless steel magnetic pump. Turn the magnetic pump by hand to see if the magnetic pump is flexible.
(2) Add bearing lubricating oil to the bearing body, observe that the oil level should be at the center line of the oil mark, and the lubricating oil should be replaced or replenished in time.
(3) Unscrew the screw plug of the pump body of the magnetic pump, and fill with 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 try to see if the rotation direction of the motor is correct.
(6) Turn on the motor. When the magnetic pump is running normally, open the outlet pressure gauge and the inlet vacuum pump to see the proper pressure, then gradually open the gate valve, and check the motor load at the same time.
(7) Try to control the flow and head of the magnetic pump within the range indicated on the label to ensure that the magnetic pump runs at the highest efficiency point in order to obtain the greatest energy-saving effect.
(8) During the operation of the magnetic pump, the bearing temperature must not exceed 35C, and the maximum temperature must not exceed 80C.
(9) If abnormal sound is found in the magnetic pump, stop immediately and check the cause.
(10) To stop using the magnetic pump, first close the gate valve and pressure gauge, and then stop the motor.
(11) During the first month of operation, the magnetic pump should change the lubricating oil after 100 hours, and then change the oil every 500 hours thereafter.
(12) Adjust the packing gland frequently to ensure that the leakage in the packing chamber is normal (it is better to leak out as drips).
(13) Regularly check the wear of the shaft sleeve, and replace it in time when the wear is large.
(14) When the magnetic pump is used in the cold winter season, after stopping, unscrew the drain plug at the bottom of the pump body to drain the medium. Prevent freezing and cracking.
(15) If the magnetic pump is out of service for a long time, it is necessary to disassemble the pump completely, wipe off the water, coat the rotating parts and joints with grease and install them, and keep them properly.
