1. Structure. Stainless steel magnetic pump mainly includes motor, bracket, external magnetic cylinder (active rotor), internal magnetic cylinder (driven rotor), isolation cover, sliding bearing, transmission shaft, impeller and pump body, etc. Among them, the magnetic coupler, which is also called permanent magnet coupling and magnetic coupling, is composed of inner magnetic cylinder, outer magne...

During the use of the fluorine-lined magnetic pump, the phenomenon of the impeller rubbing the shell will occur, and it is a very easy cause. Generally, in the process of handling, the base damage, mechanical overload, and over-current impurities will damage the normal use of the impeller, resulting in the displacement of the central shaft, distortion damage, the impeller will begin to rub the she...

Will the magnetic pump be degaussed for a long time? The reasons for the degaussing of the internal and external magnetic rotor of the magnetic pump: the high temperature and the dry rotation of the magnetic pump are the direct causes of degaussing. There are many reasons why the temperature is too high. If the flow rate is too small for a long time in operation or the outlet valve close...

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...

The failure of magnetic pump to pump liquid is easy to occur, and there are many reasons. So what should we do with it? First of all, we should check whether there is air leakage in the suction pipeline of the magnetic pump, check whether the air in the suction pipe is discharged, whether the amount of liquid injected into the magnetic pump is enough, and whether there is debris blockage in t...

What is the working principle of centrifugal pump. Centrifugal pump is widely used in chemical production. Room temperature liquids such as ethylene glycol and water are transported by centrifugal pump. The centrifugal pump is driven by an electric motor, the pump body and the suction pipe are filled with liquid, the motor drives the impeller to rotate at a high speed, and the impeller drives...
