Heng Yang Heavy Industry Dust and Gas Industry Explosion-proof Brake BYWZ5-300/80 Imported Sealed Effective

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 braking 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 to work suddenly, whether there is a situation that the brake pedal feels high and hard or there is no free travel, and whether there is a situation that it is difficult for the car to start or travel with difficulty, and whether there is a situation that the brake runs away from the road. The brake is not functioning well. Poor braking efficiency should be checked to see if there are any faults in the master cylinder, distributor pump, brake and 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 plus difficult, 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 maintenance personnel on the brake inspection, maintenance and repair methods are not appropriate may lead to lift brake damage.

The correct way to open the hydraulic brake

　　How to use the hydraulic brake to effectively extend the service life of the product? How to not damage the product? Next hydraulic brake--Tianjin brake to give you a careful explanation of this knowledge, I hope you can help.

　　1. Often increase the lubricant in the movable part of the hydraulic brake.

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

　　3. Check the length of the armature stroke regularly. 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 restore the smallest clearance between the braking surface and the turntable. If the armature stroke length increases above the normal value, it may greatly reduce the suction.

　　4. Regularly check the mechanical wear and tear of the movable parts, and eliminate the dust, flower hair and dirt on the surface of the solenoid parts.

　　5 often check the bolt fastening degree, especially to tighten the electromagnet bolts, electromagnet and shell bolts, yoke bolts, electromagnet coil bolts and wiring bolts.

　　The above five points, that is, when we use the hydraulic brake, to focus on a few points, and everyone in the use of this product is, we must pay attention to its use, to avoid causing equipment damage.

The conditions for the hydraulic brake to work reliably

　　1. The relative humidity of the surrounding air is not greater than 85% (20±5℃).

　　2, the surrounding medium, no enough to corrode the metal and destroy the insulation of the gas and dust.

　　3、The brake is surrounded by class B insulation, and the voltage fluctuation does not exceed +5% and -15% of the rated voltage, and its working mode is a continuous working system.

　　4, the installation should ensure the matching accuracy of the drive shaft part and the brake.

　　5、The brake disc of the hydraulic brake should be used without oil pollution.
