Explanation Of The Working Principle And Characteristics Of The Frame Type Magnetic Powder Clutch

The magnetic powder brake is based on the electromagnetic principle and uses magnetic powder to transmit torque. The magnetic powder brake can transmit a certain amount of torque regardless of the slip. It has fast response speed, simple structure, no pollution, no noise, no shock vibration, and saves energy. Etc. It is a multi-purpose, high-performance automatic control element.
The magnetic powder clutch has the advantages of fast response speed, simple structure, no pollution, no noise, no shock vibration, energy saving, etc. It is a multi-purpose and excellent performance automatic control element. It is widely used in printing machinery, paper machinery, bag making machinery, paper making machinery, wire and cable machinery, winding machinery and other industries.
The sealed cavity should be filled with liquid before starting. For conveying solidified medium, the sealed cavity should be heated by steam to melt the medium. It must be cranked before starting to prevent the soft ring from breaking due to sudden start. For mechanical seals using pump external oil seal systems, the oil seal system should be activated first. Finally stop the oil seal system after stopping. After the hot oil pump is stopped, the cooling water in the oil seal chamber and the end face seal cannot be stopped immediately. The cooling water should be stopped when the oil temperature at the end face seal drops below 80 degrees, so as not to damage the seal parts.
The characteristics of the base magnetic powder clutch are explained as follows:
1. The excitation current has a linear relationship with the torque: The rotation transmitted by the magnetic powder device is roughly linear with the magnitude of the excitation current. Generally speaking, within 5 to 95% of the rated torque, the exciting current is directly proportional to the torque.
2. Stable slip torque: When the exciting current remains unchanged, the torque will be stably transmitted without being affected by the slip. The stationary and rotating torques are unchanged. Therefore, as long as the current is controlled, the magnitude of the torque can be controlled.
3. Fast response characteristics: The non-response time, torque rise time, and torque fall time of magnetic powder clutches and brakes are extremely short, so it can be used for frequent start-stop, commutation.
4, small control power: high power amplification, can use a small exciting current to control a large transmitted power, easy to achieve automatic control.
5. Stable operation: no vibration, no impact, low noise.
6. Overload protection: Under the condition of torque overload, the automatic slip operation plays the role of overload protection.

How to use the base magnetic powder clutch:
1. In the process of transporting the magnetic powder clutch of the machine base, the magnetic powder is often gathered somewhere, and sometimes it even gets stuck. At this time, as long as the entire brake or clutch is turned 180 degrees, tap with a wood hammer a few times to loosen the magnetic powder. Or use the lever to rotate the shaft left and right, as long as it is turned. It is recommended to choose a clearance fit for the connection fit of the coupling. Axial tapping is strictly prohibited. Run-in should be performed before use. First, run at 20% of the rated current for a few seconds, and then power off and then on again.
2. Magnetic powder brakes, clutches, and shaft-joint joints should be used as much as possible. It is not supported to use the radial transmission main transmission. Such as gear pulleys.
