1. The main types of leak-free pumps and leak-free pump structure, including shielding pumps, magnetic pumps, positive displacement diaphragm pumps, electromagnetic pumps and so on. According to engineering practice, this article describes the non-leakage pump shielding pump and magnetic pump, foreign literature often referred to as the shaft seal pump. 1.1 shield pump leak-free pump, shield pump used widely. The shield pump is mainly composed of a pump body, an impeller, a stator, a rotor, front and rear bearings, and a thrust plate. The motor and the pump are integrated. The shield and the rotor are separated by a shielding sleeve made of non-magnetic thin-walled material. The rotor is supported by the front and rear bearings Immersed in the transport medium. After the stator windings are energized, the electromagnetic energy can be transmitted through the shielding sleeve to drive the rotor to rotate, which in turn drives the impeller to transport the medium. 1.2 Magnetic Pump Magnetic pump is installed on the pump shaft and the motor shaft, the magnetic force generated by the rotor, the motor torque is passed to the pump shaft, and then drive the impeller to send medium. When the motor rotates, the outer magnet rotor attracts each other through the isolation sleeve and the inner magnet rotor to drive the pump shaft and the impeller to rotate. The same number of magnet blocks inside and outside the rotor, forming a one-to-one relationship between the poles, the two synchronous rotation. As the isolation sleeve will be completely closed shaft, so as to achieve no shaft seal, no leakage.
