Dianli DYW series hydraulic power drum brake for mine belt conveyor






DYW series hydraulic power drum brake for mine belt conveyor
product description
DYW series of mining belt conveyor with electric hydraulic drum brakes (hereinafter referred to as brake) implementation of JB / T6406-2006, AQ1043-2007, QB / HNZD1-2013 standard.

Second, the use of conditions:
1, use: DYW series of mining belt conveyor with electric hydraulic drum brakes for coal mine belt conveyor brake;
2, the ambient temperature: -25 ℃ ~ +40 ℃ (below -25 ℃ see see the instructions for use)
3, the relative humidity of air is not greater than 90%;
4, the workplace of the altitude of not more than 2000 meters;
5, the surrounding environment pollution level allowed to 3;
6, "coal mine safety regulations" to allow the use of coal mine underground environment;
7, the power supply for the three-phase AC power: 50HZ 380V, 660V, 1140V, motor insulation grade F-class.
Third, the structure and working principle:
DYW series of electric hydraulic drum brakes by the brake frame and match the BED series of explosion-proof power hydraulic pusher composed of two parts. The working principle is as follows: When the mechanism is de-energized, when the work is stopped, the actuator of the brake - the pusher is also powered off (or deferred), stops the drive (thrust elimination), then the spring force of the brake spring The brake arm is transmitted to the brake shoe so that the brake face produces a predetermined pressure and a prescribed braking torque is established to act as a brake; when the mechanism is energized, the actuator of the brake is also energized and rapidly Produce enough thrust to push the putter, forcing the brake spring to further compress the brake arm to both sides of the outside, so that the brake shoe brake cover from the brake wheel to eliminate the brake surface pressure and braking torque, Stop the braking effect.
