Introduction of magnetic powder clutch
Magnetic particle clutch is a type of auto-control, the drive unit (inlet shaft) and the driven unit (outlet shaft) are concentric installed on the shell by the bearing,the shell(yoke) is equipped with a coil, and magnetic powder with high conductivity are filled in the gap between the two unit.When the coil is not energized, no torque between the drive unit and the driven unit. But if the coil is energized, it will form a vertical orientation magnetic field, during the rotation moment,the magnetic power will connect into chains along the magnetic flux, interaction between the two units work surface,and then produce tangential friction torque to transfer torque.This is widely used to control the tension of rewind.
Application of magnetic powder clutch
Due to the characteristics above, magnetic power clutch and magnetic power brake have been widely used to control the tension of rewind and unwind in papermaking, printing, plastics, rubber, textile, printing and dyeing,wire and cable, metallurgy and other relevant rolling and coiling processing industry. In addition, the magnetic particle clutch can be used to buffer start, overload protection and control speed.
1.Don't overload, meanwhile cool to appropriate temperature
The value of the torque/rotational speed/slip power should be less than the rated value. The cooling mode(natural cooling/forced air cooling/water cooling) should depend on the maximum slip power when it works and the cooling air should pass the water and oil filter. The temperature detector and the alarm should be installed to prevent high temperature which can affect the service life of the magnetic powder.(the highest temperature is 80 degree)
2. Concerning the torque
After the high quality magnetic powder clutch and single shaft clutch working, the magnetic powder will be in grinding at the beginning which leads to the torque decreasing slightly, but the gap can be compensated through adjustment the current.
3.Concerning the service life
The life of the magnetic powder clutch and magnetic brake rely on the life of the magnetic powder. Generally speaking, its service life is 4500-7500hours in the state of non overloaded; but its service life can extend several times in some cases, such as: the working torque of the magnetic powder clutch/brake,relative slip rotational speed and slip power can be reduced to 50%-70% of the rated value. This is to say, the margin can be enlarged as soon as possible when designing.
