Permanent neodymium magnetic coupling and magnet gear is non-contact power transmission device by magnetic attraction and repulsion force. The permanent magnet coupling is a new type of coupling that connects the prime mover and the working machine through the magnetic force of the permanent magnet. It does not need a direct mechanical connection, but uses the interaction between rare earth permanent magnets to penetrate Transmission of mechanical energy through a certain space distance and the characteristics of material materials. The emergence of magnetic couplings has completely solved the leakage problem of dynamic seals in some mechanical devices. This product is widely used in sealed transmission machinery in chemical industry, electroplating, papermaking, pharmaceutical, food, vacuum and other industries.
The magnetic coupling consists of an outer rotor, an inner rotor, a spacer, and a bearing system. The pump shaft connecting the pump and the motor is completely enclosed in the spacer. In various chemical equipment such as polyurethane foaming machines, the shaft end of the high-pressure metering pump is connected to the motor. During the production process, leakage of various chemical liquid raw materials from the pump shaft of the metering pump occurs, which is harmful to production. Environmental pollution and waste of raw materials are serious. The magnetic coupling is the principle that the magnetic force can transmit the torsional moment in space, and it is applied to the shaft end seal of each high-pressure metering pump. The motor drives the outer magnet to rotate and transmits the torsional moment through the space, so that the inner magnet on the shaft of the high-pressure metering pump sealed in the isolation sleeve rotates synchronously, canceling the dynamic seal of the pump shaft and changing the static seal, and realizing a fundamental solution to the problem of polyurethane During the production process of chemical equipment such as high-pressure foaming machines, liquid raw materials leak from the pump shaft of the metering pump. The advantage of using a magnetic coupling is that it cancels the mechanical seal of the pump, and completely eliminates the inevitable disadvantages of running, popping, dripping, and leaking in the mechanical seal of the centrifugal pump. It is a better choice for zero leakage and no pollution. of intrinsic safety. The flow-passing parts of the pump are made of stainless steel and engineering plastics, which can achieve the purpose of corrosion resistance. The magnetic coupling is integrated with the pump body, which has the characteristics of compact structure and the magnetic coupling can protect the transmission motor from overload. Fewer wearing parts, easy maintenance and extended service life.

Shipment: Magnetic coupling can be shipped by Air, Express, Truck and by sea. But it must be shielded if by air or Express.
How to promise the quality: Quality is our culture! To ensure our quality, all magnets are produced with 100% new standard material rather than recycle or bad material. Besides our professional QC department will inspect the magnet for each stage, including magnet grade, coating, dimension, tolerance and pulling force for pot magnet, magnetic hook, fishing magnet or other magnetic assemblies like magnetic coupling. So that our magnet pass rate is as high as 99.5%.
