Structure and principle of engineering plastic magnetic pump

The engineering plastic magnetic pump is a new product that applies the working principle of permanent magnet coupling to the centrifugal pump. The pump has the characteristics of compact structure, beautiful appearance, small size, low noise, reliable operation and convenient repair. What is its working principle? The following is an introduction to the working principle of the engineering plastic magnetic pump.

Engineering plastic magnetic pump is the full name of engineering plastic magnetic drive centrifugal pump, its structure is generally composed of motor, magnetic coupling and engineering plastic centrifugal pump. Its main feature is that the magnetic coupling is used to transfer power, and there is no leakage at the bottom of the pump. when the motor drives the outer magnetic steel of the magnetic coupling to rotate, the magnetic force line passes through the open ground and the isolation sleeve and acts on the inner magnetic steel to make the pump rotor rotate synchronously with the motor and transfer torque without mechanical contact.


At the power input of the pump shaft, because the liquid is closed in the stop isolation sleeve, there is no dynamic seal, so there is no leakage at the bottom of the pump. The types and basic parameters of CQ series magnetic pumps conform to JB/TQ786-89 "Type and basic parameters of small Magnetic driven centrifugal pumps" and "Supplementary provisions of three Standards of small Magnetic driven centrifugal pumps".
