YPZ2 series electric hydraulic arm disc brake pads

Electric hydraulic arm disc brake consists of electric hydraulic thruster and block brake frame. It involves mechanical, Fluid mechanics, hydraulic, electromagnetic and other disciplines. Its working principle is to convert the electrical energy of the driving device into mechanical energy, and through the rotation of the impeller, the liquid flow in the cylinder forms a high and low pressure chamber to push the piston upward, thereby transforming the vertical movement into left and right swing of the brake arm through the lever mechanism, and completing the brake release. The main auxiliary function of the product is the automatic equalizing device for backtracking. The technical working principle is to rigidly connect the equidistant device to the brake arm, and maintain the automatic equalizing of backtracking on both sides when the brake arm is opened through the transmission pairs of the left and right connecting plates. The technical research results of this project carried out by our company are at the domestic advanced level, especially in the key technical indicators of temperature rise and rise and fall time. The product has the advantages of light weight, low noise, good heat dissipation performance, stable work quality, and reasonable price. As a very important safety control device, it is widely used in lifting, metallurgy, mining, ports, construction and other machinery

Outdoor rain and snow erosion or corrosive gases and media should use anti-corrosion products. Friction pad refers to the friction material pushed and squeezed onto the brake disc by the clamp piston. The friction pad is divided into friction material and base plate, both of which are directly pressed together. The outer radius of the friction pad is only equal to the inner radius, indicating that the ratio of the outer radius to the inner radius of the friction pad is not higher than 1.5. If this ratio is too high, there will be a significant difference in circumferential velocity between the outer edge and inner side of the pad during operation, resulting in uneven friction damage and a ring to ring ratio of contact area, ultimately leading to a significant change in braking torque. The second initial pioneer applied his experience and knowledge of airships to create a twin engine with steel shafts and aluminum blades as his 14 propellers. Some of his research and development used curved aluminum plates for blades, resulting in airfoil shapes

When replacing the friction plate, it is necessary to remove the entire brake. After replacing the friction plate, reinstalling it is very inconvenient. Especially for fans above 1.5MW, large sized yaw brakes are installed, usually weighing over 200 kilograms, with a total of 12 installation bolts, each with a tightening torque of over 2000 Nm. In addition, the space inside the fan compartment is very small, making it difficult to replace (if the time to remove or tighten a bolt is calculated as 5-6 minutes, the time to remove and tighten a dozen bolts alone would take two to three hours). The maintenance workload and cost of the owner have greatly increased.

2. The gap between the friction plate and the brake body cannot be adjusted. As the friction plate wears, the gap between the friction plate and the brake body gradually increases over time. At this point, the piston sealing ring will be subjected to tangential force, which will affect the service life of the sealing ring and increase the possibility of oil leakage
