Coupling Shafts Pump Couplings Power Transmission Couplings
Introduction of Power Transmission Couplings
As one of the newly-developed coupling, magnetic coupling is for transmitting torque by magnetic components. It is ideal for torque transmitting between the hazardous inside and outside parts of the high pressure vessel. Magnetic coupling is a key component to achieve non-contact torque transmission and complete no-leakage.
Magnetic coupling is composed of outer magnetic rotor, inner magnetic rotor and isolation cover. The outer magnetic rotor is connected with motor and exposed outside. The inner magnetic rotor and the pump shaft are integrated together, and the whole rotor is contained in the pump housing and the spacer sleeve and is immersed in the transmission medium.
The spacer sleeve, which is between the inner and outer rotor, is fixed on the pump housing so that the pump housing and the isolation sleeve to be a mutually connected and comple tel: +86~13 0571 88828y sealed chamber.
Magnets are closely arranged along the circumferential direction on the outer cylindrical surface of inner rotor and inner cylindrical surface of outer rotor, forming a combination of push-pull magnetic circuit.

Operating Process Attentions
Magnetic coupling is the middle connecting part of each motion mechanism, it has a direct impact on the normal operation of each motion mechanism.
Therefore, care mu EPT be taken when using:
Magnetic couplings are not allowed to have more than the specified axis skew and radial displacement. If the problem is serious, the transmission capacity will decrease and eventually lead to the transmission parts scrapped.
A: The axis skew can cause friction between inner/outer rotor and spacer sleeve, finally lead to rotors and isolation sleeve stuck and scrapped.
B: Problems in the installation of the inner/outer rotor bearing finally lead to rotors and isolation sleeve stuck and scrapped.
C: Magnetic coupling external accessories such as the installation of the rack or bolt mu EPT not have loose defects.
D: Be sure to clean up the metal debris and note that there is no metal debris on the inner/outer rotor surface.
E: After installing, manually rotate the motor wind blade to make sure that the unit is functioning smoothly and free of blocking phenomenon.
F: Bearings should be lubricated periodically, usually 2-3 months, in order to avoid serious consequences caused by severe wear.
G: The key of the magnetic coupling should cooperate closely without loose.
Project of EPT Magnetic Couplings
Magnetic drive pumps are sealess pumps that use a balanced magnetic field to move fluid through the pump. The drive magnet and inner magnet are separated by a isolation housing, creating a sealless containment. Due to the simple structure, magnetic pumps save maintenance time of replacing sea EPT and dealing with hazardous leaks.
Magnetic drive pumps are widely used in surface treatment, water treatment, chemical processing, food processing and fluid handling needs in a variety of EPT equipment.
