Explosion-proof brake for dust and gas industry YWZ9-250/B30 for Hengyang Heavy Industry Coking Plant

Disc brake The disc brake is a hydraulic actuator applied to the braking system of the mine hoist, the exact name should be: normally closed rear-mounted cylinder disc brake, using more rear-mounted cylinders, when the hoist starts, the hydraulic station outputs pressurized oil to open the brake, and the hoist starts to work, and when the work brake is applied, the hydraulic station raises or lowers the pressure according to the working conditions, and the brake provides the opposite braking force. When the hydraulic station raises or lowers the pressure according to the working condition, the brake will provide the opposite braking force, and in case of an accident, the pressure of the hydraulic station returns to the residual pressure, and the brake stops the hoist in the shortest time with the maximum braking force.

Structural features:

1、Compact structure Although the axial size of the power loss brake is small, the braking torque is large enough.

2、Response quickly The spring device is used to form the braking torque, and the spring reset time is the braking response time.

3、Long life The new friction material used in the electrostatic brake determines the high life performance.

The brake can work reliably under the following conditions:

1、Relative humidity of the surrounding air is not more than 85% (20±5℃).

2、No gas and dust in the surrounding medium that is sufficient to corrode the metal and destroy the insulation.

3, the brake around the use of class B insulation, voltage fluctuations do not exceed +5% and -15% of the rated voltage, and its mode of operation for the continuous work system .

4. When installing the brake, it should be ensured that the transmission shaft part and the brake are matched with the precision.

5、The brake disc must be used without oil pollution.
