YPZ2-630*30II/E121-L-MSK1 Electro-hydraulic Disc Brakes

YPZ2 - 630*30II/E121 - L - MSK1 is a member of the YPZ2 series electro - hydraulic disc brakes. Each part of its model corresponds to specific parameters, and it inherits the excellent performance of the YPZ2 series while having targeted configuration designs. Below is a detailed introduction to its model meaning, core advantages and application scenarios:

Model Parameter Interpretation

Each segment of the model has a clear meaning, which helps to quickly grasp the key parameters of the brake:

Core Advantages

Easy and low-cost maintenance

Convenient replacement of brake linings: The non-asbestos brake lining of this brake adopts a plug-in design. When the lining is worn to a certain extent, it can be replaced quickly without complicated disassembly of the whole brake structure, which saves maintenance time. Meanwhile, there are various material options like semi-metal and powder metallurgy for the lining to adapt to different working conditions.

Reduced adjustment workload: It is equipped with an automatic wear compensation device. During the long-term use of the brake, the device can realize stepless automatic compensation for the shoe clearance and braking torque, keeping them stable and avoiding the trouble of frequent manual adjustment. In addition, the main swing hinge points are equipped with self-lubricating bearings, which do not need additional lubrication during the whole service cycle and reduce daily maintenance work.

Intuitive torque adjustment: The braking spring is arranged in a closed square tube, which can prevent the spring from being damaged and polluted by the external harsh environment. There is a braking torque scale on one side of the square tube. Operators can directly read the data and adjust the braking torque according to the working requirements, which is very intuitive and convenient.

Stable and reliable braking performance

Fast and balanced braking: Its braking closing time is only 0.25 - 0.4 seconds. When an emergency occurs to the mechanical equipment, it can quickly respond to achieve braking and effectively avoid safety accidents. Moreover, it is equipped with an interlocking clearance equalization device and a shoe automatic positioning device, which can keep the clearance of the brake shoes on both sides consistent all the time and completely avoid the problem that one side of the brake lining adheres to the brake disc due to uneven clearance.

Strong safety early warning capability: The MSK1 in the model represents additional functional configurations including limit switches. These switches can provide interlocking protection signals for the host PLC, such as the opening and closing status of the brake and the wear limit alarm of the brake lining. When the brake fails or the lining is worn to the limit, it can send out a signal in time to realize automatic safety monitoring.

Strong environmental adaptabilityThe brake is matched with the Ed121 electro-hydraulic thruster that meets the DIN15430 standard. The thruster has flexible action and long service life. When equipped with a delay valve, the brake can achieve delayed closing, making the braking process smoother. In addition, the brake can work normally in the environment of -20℃ - +50℃ with the relative humidity not exceeding 90%. For outdoor or harsh working conditions with rain, snow erosion or corrosive gas, the anti-corrosion type of this brake can be selected to ensure stable operation.

Reliable emergency responseIt is designed with a standard manual release device. In case of sudden power failure of the equipment or failure of the electro-hydraulic thruster, the operator can manually release the brake. This avoids the economic loss caused by the equipment being stuck and unable to move, and also facilitates the maintenance personnel to carry out maintenance and repair work on the faulty equipment.

Usage Instructions

Operating Conditions

Environmental requirements: It should be used in an environment where there is no flammable, explosive and corrosive gas. The ambient temperature should be controlled between -20℃ and +50℃, and the relative humidity should not exceed 90%. If it is used in extremely cold areas below -20℃, the hydraulic oil of the thruster should be replaced with YH - 10 aviation hydraulic oil or a heater should be equipped as required.

Power supply requirements: The standard matching power supply is three - phase AC 380V and 50Hz. If a power supply with other voltages or 60Hz frequency is needed, it should be clearly stated when placing an order for customization.

Typical Application Scenarios

Lifting and transporting machinery: It is suitable for the lifting and running mechanisms of bridge cranes, gantry cranes and other equipment. Its stable braking torque can ensure that heavy objects are stably parked during the lifting process, preventing safety accidents such as slipping and falling of heavy objects.

Port loading and unloading equipment: It can be applied to shore bridges, container gantry cranes and ship unloaders in ports. It can cope with the high - frequency and high - intensity braking operations during goods loading and unloading, and can adapt to the humid and salty working environment in ports.

Metallurgical and mining equipment: In the metallurgical field, it can be used for the braking of continuous casting machines, rolling mills and other equipment, withstanding the high - temperature and dusty working environment. In mines, it is applicable to mining hoists and belt conveyors. The delayed braking function can avoid material backflow or equipment impact caused by sudden braking.

Other fields: It can also be used in the braking systems of wind power generators and large construction machinery such as crawler cranes, providing reliable braking protection for the stable operation of various mechanical equipment.
