Description

Fluorine-lined split magnetic pump Technical Field The utility model relates to the technical field of magnetic pumps, in particular to a fluorine-lined split magnetic pump. Background The magnetic pump is a fluid conveying device for transmitting power by utilizing magnetic force, and is widely applied to the industries of chemical industry, pharmacy, food, environmental protection and the like. The working principle is that the motor drives the built-in rotor to generate a rotating magnetic field so as to drive the impeller in the pump to rotate, thereby realizing the liquid delivery. The magnetic pump has the greatest advantages that the magnetic pump has no leakage, the shell of the magnetic pump is isolated from the internal fluid, the leakage and pollution of liquid are effectively avoided, and the magnetic pump is suitable for conveying volatile, toxic or corrosive liquid. In addition, the magnetic pump has simple structure, convenient maintenance and low noise in operation, and is widely applied to various occasions needing tight sealing and safe conveying. In the traditional magnetic pump, only the bottom of the impeller is generally positioned, so that the impeller is poor in stability and easy to wear when rotating.
