[Asia pump network hearing] Magnetic pump is a centrifugal pump with a magnetic coupling, also known as magnetic coupling pump, referred to as magnetic pump. Has been widely used in computer water cooling systems, solar fountains, desktop fountains, handicrafts, coffee machines, drinking fountains, soilless cultivation, washing teeth, water heaters pressure, hot water circulation, swimming pool water cycle filter, , Play an important role in daily life, then how exactly does it work, what is the principle of operation? Xiaobian below for everyone to interpret, so that we better understand the magnetic pump. How does the magnetic pump work? Magnetic pump in operation. Leakage may occur due to insufficient sealing of isolation sleeve, so for safety reasons. Sometimes it is necessary to install a double shield with leakage display. The magnetic coupler is used to transmit power to the centrifugal pump. It consists of an outer magnet rotor and an inner magnet rotor. The outer magnet bearing is fixedly connected with the motor bearing. The inner rotor is mounted on the bearing together with the impeller. Both the outer and inner magnet rotors are equipped with permanent magnets, each with a different pole facing each other. Attract each other with the help of a magnetic division. When the outer magnetic turn the operation, the inner magnetic rotor will be synchronized (speed is the same). Centrifugal pumps with magnetic couplers, also known as electromagnetic or magnetic pumps, can now achieve powers of up to 400 kW. As the torque that needs to be transmitted increases, the rotor angle between the shaft and the magnet also increases. If the torque to be transmitted exceeds the maximum range (breaking torque). Then, the coupler loses its function and the inner rotor stops working. under these circumstances. The engine must be shut down and restarted in order to regain synchronized operation. For cage induction motors. There is no such problem (although for centrifugal pumps this problem does not occur during operation if the measurements are correct). Because of its operation and start-up can be carried out asynchronously. The isolation sleeve is installed in the gap between the outer magnet rotor and the inner magnet rotor (two layers may be required for the sake of completeness). Pump can be completely sealed. Centrifugal pumps driven by electromagnetic couplers are used similar to shielded pumps. The above is the working principle of the magnetic pump, as well as the magnetic coupler can not be confused with the electromagnetic coupler. Electromagnetic couplers are used to switch or provide protection against shock loads. Industry Internet (Xiamen) Technology Co., Ltd.
