Abstract

The invention relates to a magnetic coupling device, which is provided with a shell, an impeller and a drive magnet. The interior of the shell is divided into a drive part connection area and a driven part connection area by a cylindrical partition plate; a locating shaft which is fixedly connected onto the partition plate and is coaxial with the partition plate is arranged in the driven part connection area; the impeller is rotatablely sheathed onto the locating shaft in the driven part connection area; the drive magnet is rotatablely sheathed onto the partition plate in the drive part connection area; a bell socket part of the impeller is provided with a driven magnetic ring; and a bell socket part of the drive magnet is provided with a drive magnetic ring. The magnetic coupling device is simple in structure and convenient in assembling. Transmission is performed by utilizing the magnetic coupling principle, and therefore, the problem that leakage is brought by dynamic seal is fundamentally solved.

Description

technical field [0001] The invention relates to a transmission part, in particular to a magnetic coupling device. Background technique [0002] Pumps and fans are widely used in chemical, petroleum, agricultural production, mining, metallurgy, electric power and other industrial production. Among them, the pump is mainly used to transport liquid in these applications. Because the traditional pump is directly driven by the motor shaft, the motor shaft of the pump is a dynamic seal, which is prone to leakage. When the transmission pump is used to transport chemical liquid, since the chemical liquid is corrosive, once leakage occurs, the service life of the pump is likely to be reduced and there is a certain safety hazard. Contents of the invention [0003] The purpose of the present invention is to provide a magnetic coupling device with simple structure, good transmission effect and effective solution to the leakage problem caused by the dynamic seal. [0004] The techni...
