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
The present invention relates to a kind of transmission part, particularly a kind of magnetic coupling device.
Background technique
In the industrial production such as chemical industry, oil, agricultural production, mining industry, Metallurgy Industry, electric power, be widely used as pump, blower fan etc.Wherein pump in these are used mainly for delivery of the effect of liquid.Conventional pump is owing to adopt the motor shaft direct-drive, so the motor shaft place of pump is motive sealing, the problem of leaking occurs easily.When drive pump during for delivery of chemical liquid, because chemical liquid has corrosivity, reduce easily the working life of pump and have certain potential safety hazard in case occur leaking.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, transmission is effective and can effectively solve the magnetic coupling device of the leakage problem that is brought by motive sealing.
The technological scheme that realizes the object of the invention is: the present invention has housing, impeller and magnet; Described enclosure interior becomes driver part connection area and driven member connection area by cylindrical baffle for separating, is provided with in the driven member connection area to be fixedly connected on the dividing plate and the positioning shaft coaxial with dividing plate; Described vane rotary is socketed on the positioning shaft in the driven member connection area; Described magnet rotary sleeve is connected on the dividing plate in the driver part connection area; The socket part of described impeller is provided with driven magnet ring, and the socket part of magnet is provided with the driving magnet ring.
Above-mentioned impeller comprises blade-section and socket part; Positioning shaft in the described driven member connection area is provided with coaxial fixing rod; The socket part of described impeller is sleeved on the positioning shaft, and fixing rod passes on the blade-section with the coaxial fixed hole of socket part and by nut vane rotary is socketed on the positioning shaft.
The socket part of above-mentioned impeller from inside to outside is provided with slip ring successively, from static magnetic yokes, driven magnet ring and shell; The socket part of described magnet from inside to outside is provided with successively and drives magnet ring and drive yoke.
Above-mentioned impeller blade-section and the shell of socket part be integrated molding and forming; Described housing is moulding.
The present invention has positive effect: (1) the present invention is simple in structure, and is easy to assembly, and the inspect and change in later stage is also very easy; (2) the present invention utilizes magnetic coupling principle to carry out transmission, has broken away from traditional shaft drive, has fundamentally solved the leakage problem that is caused by motive sealing; (3) the present invention is because basically having solved leakage problem, so to improving a lot the working life of whole device, reduced user cost.
