The maintenance and debugging of the electric hydraulic push rod brake is simple and convenient

Hydraulic thrusters generally do not require maintenance, as long as the clearance between the brake pads and the brake drum is checked. If there is a deviation in the clearance, appropriate adjustments can be made. Some hydraulic thrusters may have some leaks, so it is appropriate to add No. 20 engine oil to the hydraulic thrusters; The brake pads can also be replaced, and replacement is very convenient and quick.

Installation, commissioning and maintenance of electric hydraulic brakes:

1. Installation

The brake is installed on the machine after the brake wheel is installed. The brake wheel must be dynamically and statically balanced, with a surface roughness of not less than Ra l. 6 and a hardness of not less than HB=280. When installing and fixing the brake, attention should be paid to whether the brake shoe is parallel to the brake wheel when the brake is released; In the braking state, the brake pads should stick to the brake wheels. The non parallelism and inclination in the released state shall not exceed 0.1mm within the width of the brake wheel of 100mm. The working surface of the brake wheel must not have oil stains.

2. Oil injection

Before the test run of the electric hydraulic thruster, clean and free of any dirt and mechanical impurities hydraulic oil must be injected into the cylinder. Connect the hydraulic power supply and check if the impeller rotates flexibly, if the circular spring is stuck, and if the push rod and piston move up and down without any jamming.

3. Adjustment of braking torque

By adjusting the adjusting nut of the main spring and changing the compression length of the spring, the spring force and braking torque can be adjusted to ensure that the brake operates with as little braking torque as possible.

4. Adjustment of the brake pad setback of the brake

Due to the brake's ability to automatically adjust clearance, as the brake pads wear, the clearance between the left brake pad and the brake pad can always remain unchanged, but the clearance between the right brake pad and the brake pad gradually increases with the wear of the brake pads. It is necessary to adjust it in a timely manner according to the situation to ensure that the distance between the two brake pads is basically uniform.

Electric hydraulic push rod brake consumes less power

Choosing the YWZ series electric hydraulic push rod brake is more energy-efficient than using an electromagnetic brake. Having the same diameter（ Φ Compare the brakes of 400mm brake pads: for example, the electric hydraulic push rod brake YWZ3-400/125 has a braking torque of 1120-1800Nm, the thruster motor model is YT1-12Z/10, and the motor power is 400W; The electromagnetic brake ZWZ3-400/400 model has a 100% power on duration, a braking torque of 500Nm, and a power consumption of 660W by the electromagnet. From this, it can be seen that using hydraulic push rod brakes consumes more than one-third less electricity than electromagnetic brakes, and has energy-saving effects.
