After sales maintenance of YWZ5-315/E50 electric hydraulic drum brake

Widely used for deceleration and parking braking of mechanical drive devices in lifting, metallurgy, mining, ports, docks, construction, and other fields.

Its installation dimensions and braking torque parameters comply with the JB/T6046-2006 standard. Matching Ed series thrusters

Safe and reliable performance, smooth braking, high action frequency, and adjustable braking torque.

The main swing hinge point is equipped with self-lubricating bearings, which have high transmission efficiency and long service life. During use, the distance between the two sides of the pads is always equal, avoiding the phenomenon of one side of the brake pad floating against the brake wheel due to uneven distance.

The brake spring is arranged inside the spring tube and is equipped with a brake torque scale on one side, making adjustment convenient and intuitive.

Some additional functions can be achieved by adding additional devices:

Manual release device

Releasing (opening) or closing (closing) the limit switch can realize the signal display or interlock protection of whether the brake is normally released or closed.

The use of a pusher with a lowering delay valve can achieve delayed closure of the brake.

Usage conditions and procedures:

Environmental temperature: -25 ℃~+45 ℃.

The role of brakes in equipment is so important, so it is necessary for us to pay more attention to the maintenance and upkeep of brakes in daily life: regularly check whether the brakes are in good working condition, so as to promptly identify existing safety hazards and reduce the incidence of crane accidents. Identify any abnormalities in the brake equipment through sound, and regularly inspect the internal wear of the crane brake to see if it exceeds the allowable range, whether the spring is ineffective, and whether there are many impurities and dirt in the internal components. Timely cleaning or replacement of internal components is necessary.

Due to the periodic and intermittent working characteristics of the crane, various working mechanisms are often in frequent starting and braking states. The brake has become an indispensable component of the power-driven crane's various mechanisms. It is not only a control device for the operation of the mechanism, but also a safety device to ensure the operation of the crane. The key to safety inspection is whether the brake is intact and reliable. The crane brake is installed on the shaft of the electric motor, used to brake the operation of the electric motor, so that its operation or lifting mechanism can accurately and reliably stop at the predetermined position. 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.

3. 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.
