Shanxi, Xinjiang harmony Machinery Co. Share: hoisting machine brake function basic requirements: ① When the elevator power control circuit power failure or loss of power supply, the brake can brake immediately. ② When the car carrying 125% rated load and run at rated speed traction machine manufacturers, should enable the hoisting machine brake stops. ③ elevator during normal operation, the brake should be under continuous power while maintaining the release state; after disconnecting the brake release circuit traction machine, elevators should be no additional delay is effective braking. ④ off the brake current application, at least two separate electrical means. When the elevator stopped, if one of the main contacts of the contactor is not open at the latest when the next change in the direction of Shanxi elevator traction machine, should prevent the elevator run again. ⑤ equipped with manual tray elevator riders wheel traction machine, you should be able to release the hand brake and the need to maintain a continuous force to loosen state. Shanxi, Xinjiang harmony Machinery Co. Share: traction machine Common Faults and fault handling is not floodgates A. solenoid is not energized or voltage wrong. Brakes should be careful to check the wiring and voltage. B. Bilateral spring brake arm excessive pressure. Adjust the spring pressure, according to the traction machine 2 times rated torque setting. C. brake coil is damaged (open). Multimeter measurements. D. brake gate small gap. Regulating solenoid trip. Bilateral brake arms are not synchronized gate and closing gates on both sides of the spring pressure brake arm A. uneven traction machine prices, slow gate side of the spring pressure is greater than the side gate fast. Pressure side of the spring pressure should be reduced, the braking force in ensuring sufficient premise to equalize the pressure on both sides as far as possible. B. both sides of the gate opening stroke of the brake arm is inappropriate, adjust the brake shoe clearance gate.
