What To Do if There Is a Sudden Failure In the Operation of The Magnetic Drive Pump?

Mar. 25, 2021

The magnetic drive pump is a new product that applies the working principle of the permanent magnet coupling to the centrifugal pump. The main materials are stainless steel, reinforced polypropylene, engineering plastics, etc. It has reasonable design, advanced technology, full sealing, no leakage, and corrosion resistance. Its performance has reached the advanced level of similar foreign products. Conventional classification of magnetic drive pumps:Stainless Steel Centrifugal Pump, plastic magnetic drive pumps, high temperature magnetic drive pumps, self-priming magnetic drive pumps.

Magnetic Drive Pumps

Magnetic Drive Pumps have gradually replaced mechanical seal pumps and canned motor pumps with the same performance in recent years, and have gradually become industrial environmentally friendly products. This pump has certain operating requirements, and it is inevitable that it will encounter failures during operation, but the solution is always more difficult than the difficulty, and there is no failure that cannot be solved.

Operational requirements:

If the installation position of the magnetic drive pump is lower than the liquid level, the gate valve of the suction pipeline should be opened before starting to fill the pump with liquid. If the installation position of the pump is higher than the liquid level, the pump should be primed or vacuumed before starting, and the air in the pump should be drained so that the pump and the suction pipe are filled with liquid. Because the bearing lubrication of the magnetic drive pump is completed by the conveyed liquid , So dry running is absolutely prohibited. Close the outlet pipeline gate valve. When starting, start the motor first and then close it after a few seconds to check and determine whether the direction of rotation of the motor is consistent with the direction of the arrow marked on the body. It is strictly forbidden to reverse, and restart after determining that the direction of rotation is correct.

After the magnetic drive pump is started, slowly open the outlet pipeline gate valve, and after the pump reaches the normal operating state, adjust the outlet gate valve to the required working condition range. With the discharge line valve closed, the pump should not run for more than one minute. After the magnetic drive pump is started, if the flow and head of the pump do not rise to the rated value with the increase of the motor speed, the pump should be shut down immediately, and the pump should be filled and exhausted carefully, so that the pump and the suction pipe are completely filled with liquid and then restarted . When the motor speed reaches the rated value, the flow and head of the pump also reach the rated value range or the required working condition range, and then it is regarded as normal.

The temperature rise of the motor should be checked frequently during the operation of the pump. The limit temperature of the motor should not be greater than 75C. If there is a strong heating phenomenon, it should be shut down for inspection.
