What Are The Problems With The Use Of Magnetic Powder Brakes?

- Jun 29, 2019-

  The magnetic powder brake has a characteristic that the excitation current and the transmission torque are substantially linear. It can transmit a certain torque regardless of the slip, and has the advantages of fast response, simple structure, no pollution, no noise, no impact vibration and energy saving. The magnetic powder brake is a multi-purpose, superior performance automatic control component. It has been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy, tablet presses and other unwinding and winding tension control in the coiling and processing industry.

       What are the problems with the use of magnetic powder brakes?

1. Please pay attention to moisture. 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.

When the value exceeds this value, the durability is greatly reduced. Be sure to use the above-mentioned limit temperature as the standard, and be sure to keep it within the allowable sliding work rate when using it. 1. Due to the long time during transportation or the long time of the placement, the magnetic powder filled between the two groups of cells is scattered on one side, and no magnetization is caused before the start-up.

2. Due to the low manufacturing precision of the product, the concentricity of the rotor is insufficient, resulting in uneven output torque or jamming.

3. In the production process, the excess of magnetic powder is enclosed.

4. Caused by inferior magnetic powder. 1. Before the official operation or after the device is moved, it must be evenly operated to be officially operated. In this way, a smooth torque can be generated, and the uniform operation mode is as follows: in the non-excited state, the drive side is rotated as fast as possible (after 1800 rpm) for about 1 minute, and the excitation current is set at a rated 1/4 to 1/5, one. On the side of the slewing drive side, on the one hand, open in 5 seconds, close in 10 seconds, and excite the magnet for about 20 times.

5. When choosing to purchase the magnetic powder clutch / magnetic powder brake, it is best to choose a product with guaranteed quality.发送反馈
