The maintenance and debugging of the electric hydraulic push rod brake is simple and convenientHydraulic 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. InstallationThe 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 injectionBefore 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. BYWZ9 explosion-proof brake3. Adjustment of braking torqueBy 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 brakeDue 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 powerChoosing 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.

Brakes are a safety protection device mainly used to control the movement of machinery. When selecting a brake, it is necessary to choose the appropriate one based on its usage environment. There are many types of brakes, and when purchasing from a brake factory, how should we choose the product that is suitable for ourselves?1： The selection of normally open or normally closed brakes is mainly based on the magnitude of braking torque, working properties, and working conditions. For example, the lifting and luffing mechanisms of lifting machinery must use normally closed brakes; For the operation and rotating mechanisms of various vehicles and lifting machinery, in order to accurately stop, it is necessary to control the torque and use normally open brakes.2： Consider the size of the space used. For occasions with sufficient space, external block brakes can be used. Space is limited, and usually belt type, disc type, or inner shoe type brakes are selected.3： Select the type based on the function and working requirements of the brake. The structure of hydraulic brakes is not complex, and hydraulic cylinders are the main executing components of hydraulic brakes. They are energy conversion devices that convert the hydraulic energy of liquids into mechanical energy to achieve linear reciprocating motion or reciprocating oscillation of the working mechanism. Hydraulic brake hydraulic cylinders have a simple structure and reliable operation, and are widely used in various mechanical equipment. In addition to being used alone, hydraulic cylinders for hydraulic brakes can also be combined with other mechanisms to achieve special functions. For mechanisms with high safety requirements, double brakes are generally installed to control the braking and separation of the power shaft through oil pressure, pressure relief braking, and pressure boosting separationActual drawing of YWZ9-200 workshopIt can be used in both dry oil-free and wet oil-immersed environmentsWith manual release function, the friction plate can be manually released during pressure reliefMulti friction plate structure, long service lifeThere are many types of brakes, including service brake, disc brake, crane brake, electric hydraulic brake, etc., and different brake systems can play different roles. Let's take the service brake as an example and share with you the role it can play!The motor is in a power generation state from time to time when parking or being dragged by a load. Simply put, it is in a power generation state when the speed is opposite to the torque direction. At this time, the motor will convert mechanical energy into electrical energy.Assuming that the equipment controlling the motor can only absorb energy from the grid and cannot send it back to the grid, the motor brake is needed to consume some of the remaining energy.When the brake motor is powered on, the motor and brake coil are energized together. At this moment, the magnetic disc of the brake overcomes the pressure of the tension spring and is attracted to the side of the magnetic pole group, causing the conflicting plate to detach from the brake plate, allowing the motor to start.Two types of diagrams, YWZ4 and YWZWhen the power supply is cut off, the magnetic disc is pushed out by the tension spring due to the disappearance of the magnetic field, causing the conflict plate on the magnetic disc to collide with the brake plate, and quickly braking the motor. This series of products has good friction performance of the spindle brake, low braking spark, and no damage to the dual; Yaw noise free, good friction performance, and non damaging dual brake friction materials. The friction material brake friction material technology has reached the international advanced level through technical appraisal by the provincial scientific research department

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 powerChoosing 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.
