Maintenance of magnetic pump and magnetic drive pump

It is recommended that users should do the following maintenance and upkeep work during daily use of magnetic drive pumps


It is recommended that users should do the following maintenance and upkeep work during daily use of magnetic drive pumps:

(1)Check the magnetic pump pipeline and joints for looseness.Rotate the magnetic pump by hand and see if it works properly.

(2)If any abnormal sound is found in the magnetic pump,it should be stopped immediately to check the cause.

(3)Unscrew the water inlet plug of the magnetic 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)During the operation of the magnetic pump,the bearing temperature should not exceed the ambient temperature of 35℃,and the maximum temperature should not exceed 80℃.

(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 operates at the highest efficiency point,in order to achieve the maximum energy-saving effect.

(8)Start the motor,and when the magnetic pump is running normally,open the outlet pressure gauge and the inlet vacuum pump to see if they show appropriate pressure.Gradually open the gate valve and check the motor load condition.

(9)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.

(10)When the magnetic drive 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 magnetic pump changes the lubricating oil after 100 hours,and then every 500 hours.

(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 a magnetic pump 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)If the magnetic pump is to be stopped for a long time,it is necessary to disassemble all the pumps,dry the water,and apply grease to the rotating parts and joints.
