Application areas of magnetic couplings

Application areas of magnetic couplings:

One of the successful applications of the magnetic drive coupling is its combination with the pump-the magnetic pump. In the past, it was used as a valuable special product as a last resort, but now it has a wide range of applications. Most of the liquids in petrochemical, pharmaceutical, film, electroplating, nuclear power and other industries are corrosive, flammable, explosive, toxic, and valuable. Leakage will bring waste of working fluid and environmental pollution; vacuum and semiconductor industries must prevent external gases The invasion of food, biology, and medicine must ensure the purity and hygiene of the medium. Magnetic drive couplings have found a place in these fields. It can be said that magnetic pumps are a big market for magnetic materials.

The magnetic drive coupling, especially the permanent magnet coupling, is applied to the valve. The valve stem does not pass through the bonnet, and the stuffing box is omitted, so it is called a fully enclosed permanent magnet drive valve without filler. Because the valve has no stuffing box, it can operate safely and reliably for a long time; there is no frictional torque between the valve stem and the packing, and the rotation is labor-saving; the negative pressure operation has no outside air entering. All industrial valves, including globe valves, gate valves, ball valves, and butterfly valves, can be transformed into fully enclosed valves. The reactor is a kind of mixing reaction equipment widely used in chemical plants. The stirring of liquid is often carried out under pressure. The reactants have a certain temperature, corrosiveness and volatility. Therefore, the sealing of the rotating shaft has become an important issue of the reactor. The reaction equipment with stirrer uses magnetic transmission, which can avoid the oxidation and condensation of the medium in addition to achieving absolute sealing.

Overview:

With the development of magnetic materials and the emergence of new magnetic materials, the torque transmitted by the magnetic drive coupling will become larger and larger, and the volume will become smaller and smaller, and its application range will become wider and wider, except for pumps and reactors. , Valves, hydraulic cylinders and cylinders, and other occasions that need to solve the problem of dynamic seal leakage can be applied. It can be predicted that the magnetic drive coupling will have a very broad market prospect.
