How to choose magnetic coupling

The selection steps of magnetic coupling are as follows:

? 1, magnetic coupling is a part of standardized production products. In the initial stage of selecting the coupling, we can know whether there are any coupling product types that meet the needs of use in national standards, machinery industry standards and national patents. If the coupling can't find a matching type, you can contact the manufacturer to design the coupling product by yourself.

2. The torque of the magnetic coupling should meet the requirements of the power machine of the transmission system. According to the power and rotating speed of the power machine and the working machine, the reasonable torque value of the coupling can be calculated, so as to preliminarily select the coupling.

3. After the primary selection of the magnetic coupling, the size of the coupling should be determined according to the shaft diameter and shaft hole length of the driving shaft and the driven shaft, and the specifications of the coupling should be adjusted. The model adjustment of the coupling should also consider whether the rotational speed between the driving shaft and the driven shaft connected by the coupling is consistent and whether the shaft diameter is the same.

? 4、? Finally, all factors should be considered again in the selection of magnetic coupling to ensure that the size, torque, shaft diameter and shaft hole of the coupling are suitable for the prime mover and working machinery and the working environment. After selecting the coupling model, check the strength of the key and finally determine the coupling model.

? Magnetic coupling, also known as magnetic drive coupling, is a non-contact coupling, which generally consists of two magnets, the inner magnet is connected with the driven part and the outer magnet is connected with the power part. In addition to the damping and vibration absorption functions of elastic coupling, the magnetic drive coupling is characterized by breaking the structural form of the traditional coupling and adopting a brand-new magnetic coupling principle, so that the driving shaft and the driven shaft can transfer force and torque without direct contact, and the variable seal is static seal to achieve zero leakage. Therefore, it is widely used in occasions with special requirements for leakage.

? One of the successful applications of magnetic coupling is its combination with pump-magnetic pump. In the past, it was only used as a valuable special product when necessary. Now it has a wide range of applications. Most liquids in petrochemical, pharmaceutical, film, electroplating, nuclear power and other industries are corrosive, flammable, explosive, toxic and precious, and leakage brings waste of working fluid and environmental pollution; Vacuum and semiconductor industries should prevent the invasion of external gases; Diet, biology and medicine should ensure the purity and hygiene of the culture medium. Magnetic drive couplings have found their place in these fields. It can be said that magnetic pump is a big market for magnetic materials.
