Method And Precautions For Replacing Magnetic Powder In Magnetic Powder Clutch

The magnetic powder brake is based on the electromagnetic principle and uses magnetic powder to transmit torque. The magnetic powder brake and the magnetic powder clutch are made of the latest materials and manufacture, which is the best choice for improving the equipment. The magnetic powder brake can transmit a certain rotation without being affected by the slip. Moment, has the advantages of fast response, simple structure, no pollution, no noise, no impact vibration and energy saving. It is a multi-purpose, high-performance automatic control component.

Magnetic powder brakes are also often used for dynamometer loading and braking of transmission machinery. The product of the maximum winding radius should not exceed the rated torque of the brake. Magnetic powder brakes are widely used in printing, packaging, papermaking and paper processing, textile, In the automatic tension control system of the winding device for printing, wire, cable, rubber and leather foil strip processing, the magnetic powder brake can also be used as an analog loader. The excitation current and the torque are basically linear. The excitation current can be controlled by adjusting the excitation current. The size of the moment.

The selection of the magnetic powder brake is generally determined by its maximum braking torque. The magnetic powder brake torque is independent of the rotational speed, and the fixed value is maintained. There is no difference between the static torque and the dynamic torque. The allowable slip power of the magnetic powder brake is fixed when the heat dissipation condition is constant. Fixed value, when it is running continuously, the actual slip of the magnetic powder brake should be within the allowable slip power. When the high speed is used, the torque should be reduced. During the transportation process, the magnetic powder brake often causes the magnetic powder to gather somewhere and even “card” In the case of death, it is only necessary to flip the brake as a whole to loosen the magnetic powder or use a lever to move.

      Magnetic powder is an essential material for torque transmission of magnetic powder clutch. Magnetic powder is a kind of consumable, which changes with time, temperature and quality. Magnetic powder has a certain life and needs to be replaced from time to time.

  Method / Step:

      1. Place the magnetic powder clutch on the prepared rack (reverse), the input shaft is facing down, and the output shaft is facing upwards. Pay attention to the smooth placement of the magnetic powder;

      2. Use a wrench to loosen and remove the aluminum cover fixing bolt at the end of the bolt output shaft;

      3. After removing the aluminum cover, loosen the bolts of the stator and take out the stator;

      4. After removing the stator, clean the magnetic powder left inside, and clean the inner wall with a clean rag;

      5. After cleaning up, please enclose the prepared magnetic powder in accordance with the specifications (unit is g);

      6. After adding the magnetic powder, please fix the stator, stator bolt, aluminum cover, aluminum cover bolt, etc. according to the original position. This step is very important, if it will cause leakage of magnetic powder.

       7. After the magnetic powder is sealed and fastened, please test the magnetic powder clutch and use it without any abnormality.

       Tools / Materials:

      a rag, clean and dust-free cloth for cleaning the inner wall of the magnetic powder clutch;

      Magnetic powder, newly prepared magnetic powder; wrench for loosening the bolt;

      Bracket for flat magnetic powder clutch.
