Publish Time: 2024-11-20
In modern industrial equipment, permanent magnetic drive shaft coupling for pump magnetic clutch is a new type of transmission device, which is gradually receiving widespread attention and application. This coupling connects the prime mover and the working machine through the magnetic force of the permanent magnet, without direct mechanical connection, and has many unique advantages and application value.The permanent magnetic coupling is mainly composed of an outer rotor, an inner rotor and an isolation sleeve. Magnets arranged circumferentially in NS cross mode are installed on the inner circumference of the outer rotor and the outer circumference of the inner rotor. These magnets are generally even-numbered poles. When the working surfaces of the magnets of the inner and outer rotors are aligned, they are automatically coupled, thereby realizing the transmission of mechanical energy. This structure is not only simple, but also does not require lubrication, is easy to assemble and disassemble, and is easy to maintain.The magnetic drive characteristics of the permanent magnetic coupling give it excellent sealing performance. Since the magnetic connection does not require shaft sealing, the variable seal is a static seal, so leakage-free or absolute sealing can be achieved. This feature makes it have a wide range of application prospects in sealed transmission machinery in the chemical, electroplating, papermaking, pharmaceutical, food, vacuum and other industries. Especially when dealing with corrosive liquid media, permanent magnetic couplings can prevent damage caused by the medium passing through the shaft seal, thereby extending the service life of the equipment.In addition, permanent magnetic couplings also have certain buffering and vibration reduction performance, as well as good axial, radial and angular compensation performance. These characteristics make permanent magnetic couplings more stable and reliable when transmitting torque, can limit torque transmission, achieve overload protection, and play the role of safety couplings. At the same time, permanent magnetic couplings are also easy to realize remote control and automatic control, with high process control accuracy, further improving the automation level of the equipment.In pump magnetic clutches, the application of permanent magnetic drive shaft couplings is particularly prominent. Magnetic drive centrifugal pumps, referred to as magnetic pumps, are a typical application of permanent magnetic couplings in pumps. Magnetic pumps use the good sealing performance of permanent magnetic couplings to solve the problems of running, bubbling, dripping and leakage that are difficult to solve with mechanical seals, with remarkable results. At the same time, magnetic pumps also have the advantages of simple structure, convenient maintenance, and reliable operation, and are widely used in various occasions that require leakage-free transmission.The inner and outer diameters of permanent magnetic couplings can generally be customized, and purchasing personnel can choose the appropriate manufacturer to order according to actual needs. The material of the permanent magnet is generally samarium cobalt or neodymium iron boron permanent magnet, and the specific brand needs to be determined according to the working temperature, working environment and coupling torque. The shell is generally made of stainless steel, which has good corrosion resistance and mechanical strength.With the serialization and standardization of permanent magnetic couplings, it will be provided to relevant industries as a new type of general basic component for selection and matching. In the future, with the continuous advancement of technology and the continuous expansion of applications, permanent magnetic drive shaft couplings for pump magnetic clutches will play an important role in more fields, providing more efficient and reliable solutions for the transmission and sealing of industrial equipment.Permanent magnetic drive shaft couplings for pump magnetic clutches have broad application prospects in modern industrial equipment with their unique magnetic drive characteristics and excellent sealing performance. With the continuous advancement of technology and the continuous expansion of the market, permanent magnet couplings will become an important component of future transmission devices, injecting new vitality into industrial development.
