What are the advantages of DYT permanent magnet couplers?
DYT permanent magnet coupler is a brand-new transmission mechanism, which is a pure mechanical product and is not restricted by the working environment. More suitable for flammable and explosive environment. Because the magnetic coupling is a transmission device that transmits torque through a magnetic field, there is no mechanical connection between the motor and the load shaft. When the motor rotates, the magnetic lines of force are cut in the strong magnetic field generated by the permanent magnet rotor made of a copper disk on the magnetically permeable rotor, thereby generating eddy currents in the disk, and the strong eddy currents are relatively moved between the magnetically permeable rotor and the permanent magnet rotor. By adjusting the air gap between the rotor and the permanent magnet rotor, the magnetic field is changed to achieve torque transmission and speed regulation.
Advantages of DYT permanent magnet coupler:
1. Adjustment range: permanent magnet speed regulation can be stepless speed regulation of the load in the range of 0 ~ 98%.
2. Process control can be realized, and the response speed is fast: the actuator receives the standard 4 ~ 20mA signal, and adjusts the load speed according to the input signal to meet the system requirements and the response speed is fast.
3. No-load start with small impact of DYT permanent magnet coupler: when starting the magnetic coupler, the air gap is increased to realize no-load start, which can greatly reduce the time required for the motor to start the current.
4. Reduce vibration: Because the permanent magnet governor is a non-mechanical speed regulating device, the pump and the motor are not mechanically hard-connected; the torque is completely transmitted through the air gap, which has the advantages of isolating vibration transmission and reducing vibration. The ability to eliminate vibration can reach 80%.
5.DYT permanent magnet coupler has high reliability and low maintenance: simple equipment structure, low failure rate and low maintenance cost.
6. Long service life: The service life of the magnetic coupler can reach 30 years.
7. Energy saving: By adjusting the load speed, improving efficiency, reducing pipeline loss and reducing motor load, the energy saving effect is obvious.
8.DYT permanent magnet coupler to adapt to a variety of harsh working environment, power grid voltage fluctuations, high harmonic content; flammable, explosive, humid, high dust content, high temperature, low temperature and other places.
9. No harmonic interference: non-contact mechanical connection does not produce harmonic interference.
