Dust and gas industry explosion-proof brake YWZ9-300/B30 Hengyang Heavy Industry with coal safety certificate

In order to ensure the uninterrupted operation of the hydraulic brake, it is necessary to often protect it, today for you to sort out some of the use of precautions, I hope to help you:

　　1, often in the electromagnetic brake can move some increase lubricant.

　　2, regularly check the length of the armature stroke. Because in the operation of the brake, because of the wear of the profile, the stroke length of the armature will increase. When the armature stroke length is not up to the normal value, it is necessary to make adjustments to recover the small gap between the braking surface and the turntable. If the armature stroke length increases above the normal value, it may greatly reduce the suction.

　　3、If the worn braking surface is replaced, the small gap between the braking surface and the turntable should be properly adjusted from the beginning.

　　4, often check the degree of tightness of the hydraulic brake bolts, especially tighten the bolts of the electromagnet, the bolts of the electromagnet and the casing, the bolts of the yoke, the bolts of the electromagnet coil and the wiring bolts.

　　5, regularly check the mechanical wear condition of movable parts, and eradicate the dust, flower hair and dirt on the appearance of electromagnet parts.

　　The hydraulic brake represented by YWZ9 series brake and YWZ series brake can be analysed from the four major faults to determine whether there is a situation that the brake deceleration is small and the braking distance is long when the brake is applied while the car is moving, whether there is a situation that the brake fails suddenly, whether there is a situation that the brake pedal feels both high and hard or there is no free travel when it is stepped down, whether the car has difficulty in starting or travelling with great difficulty, and whether there is a situation of brake The brake is not functioning well. If the braking efficiency is poor, check whether there is any fault in the master cylinder, sub-pump and brake, and whether there is any air infiltration in the brake line. Brake bite to see if the brake pedal has free travel or its return spring fall off, broken or too soft, pedal shaft rust stagnation and difficult to add, the master cylinder piston return spring is too soft, broken, bowl swelling blocking the return hole or return hole is blocked by dirt. Brake deflection is mainly due to the left and right side due to a side wheel brake drum and friction pad clearance is not the same or a side of the front wheel sub-pump air, hose aging or sub-pump bowl is bad or a side of the front wheel brake drum loss of round resulting in inconsistent wear. For lift brakes, the designer did not consider that uniqueness to the stroke indicator mounting would cause the stroke indicator to touch the movable indicator. Secondly, the brake is bonded, not riveted, long-term use will be due to the adhesive open glue and cause the brake tile off, or even sealing rubber aging rupture. There are also foreign objects falling into the solenoid core or rust caused by brake jamming. Caused by the brake jamming may also be the lift iron core guiding design is not reasonable, more than one connection fracture. As well as the later lift repair and maintenance personnel on the brake inspection, maintenance and repair methods may lead to lift brake damage.
