Notes On The Use Of Magnetic Powder Brakes In The Process Of Use

Magnetic powder brake and magnetic powder clutch are capable of transmitting a certain torque according to the electromagnetic principle and using magnetic powder to transmit torque. The magnetic powder brake has a fast response, simple structure, no pollution, no noise, no impact. Vibration and energy saving, magnetic powder brake, magnetic powder clutch can easily control the torque within 5% to 100% of the rated torque range by changing the magnitude of the excitation current. The excitation current is proportional to the torque it transmits. relationship.

       Let's take a look at some of the considerations in the use of magnetic powder brakes:

1. Magnetic powder brakes in normal operation, especially the newly placed magnetic powder clutches and brakes, the appearance temperature should not be higher than 80 degrees Celsius, the water-cooled brake should not be higher than 90 degrees Celsius, and the forced air-cooled type should not be 60 degrees Celsius higher. .

2. Before the magnetic powder brake is used for the first time, it is rated at 30% of rated current. After 10 seconds of operation, the power is turned off and then energized. Repeated several times to ensure the magnetic fluidity and uniform distribution.

3. The magnetic powder brake can not be used with excessive torque and speed. Otherwise, the life of the magnetic powder will drop sharply, or powder leakage or jam will occur.

4. If the magnetic powder gets wet, the performance will become unstable, so be careful not to let oil or moisture invade the inside. In particular, when it is installed in a gear box, the oil will penetrate into the inside through the shaft, so it is completely sealed with a film.

       Magnetic powder brakes are also often used for dynamometer loading and braking of transmission machinery. The output torque of the magnetic powder brake has a good linear relationship with the excitation powder current and is independent of the rotational speed or slip, and has the advantages of fast response speed and simple structure.
