Magnetic eddy current is a common phenomenon in magnetic pump. when the motor rotates the rotor through external magnetic field, the isolation sleeve is in a sinusoidal alternating magnetic field and induces eddy current on the cross section perpendicular to the magnetic force line, which is converted into heat, which is called eddy current heating. The eddy current heating of the magnetic pump wi...

1. Magnetic pump cavitation: the main causes of pump cavitation are large resistance of pump inlet pipe, more gas phase of conveying medium, insufficient filling pump, insufficient energy head of pump inlet and so on. Cavitation does great harm to the pump. When cavitation occurs, the pump vibrates violently and the balance is seriously damaged, which will lead to damage to the bearing, rotor or i...

First, the reason why the noise of the fluorine-lined magnetic pump is too loud. 1. Serious wear and tear of the shaft. 2. Serious wear of shaft sleeve. 3. The driving magnetic steel cup is in contact with the isolation sleeve. 4. There is friction between the rotating part and the fixed part. 5. Suction head exceeds or bottom valve clogs. 6. The pump is not fixed. Second, the elimination method o...

1.The working principle of magnetic pump The magnetic pump consists of three parts : pump, magnetic drive and motor. The core component magnetic drive is composed of an external magnetic rotor, an internal magnetic rotor and a non-magnetic isolation sleeve. When the motor drives the external magnetic rotor to rotate, the magnetic field can pass through the air gap and non-magnetic material, drive ...
