One of the successful applications of magnetic drive couplings is its combination with pumps – magnetic drive pumps. In the past, it was used as a precious special product when it had to be used, 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 expensive. Leakage will cause waste of working liquid and environmental pollution; vacuum and semiconductor industries must prevent external gas The intrusion of food, biology, and medicine must ensure the purity and hygiene of the medium.
The magnetic transmission coupling is applied to the valve, the valve stem does not pass through the valve cover, and the stuffing box is omitted, so it is called a fully enclosed non-filling permanent magnet transmission valve. Since the valve has no stuffing box, it can run safely and reliably for a long time; there is no frictional moment between the valve stem and the packing, and the rotation is labor-saving; negative pressure operation does not allow external gas to enter. All industrial valves such as globe valves, gate valves, ball valves, and butterfly valves can be transformed into fully enclosed valves.
The reaction kettle is a kind of mixed reaction equipment widely used in chemical plants. The stirring of the 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 in the reaction kettle. The reaction equipment with agitator uses magnetic drive, in addition to achieving sealing, it can also avoid the oxidation and condensation of the medium.
With the development of magnetic materials and the emergence of new magnetic materials, the torque transmitted by magnetic transmission couplings will become larger 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.
