The Flexible Hydraulic Brake Deviceis mainly used as controllable stop for large mechanic-electronic equipment, sometimes used to regulate or limiting machine movement speed. It selects normally closed type structure, so it suit to all kinds of electrical equipment. The hydraulic soft brake system device is cooperate with power control device, it can be used to the large electrical and mechanical equipment parking slow down in the 0.1 3 32m/ s2.In the load conditions starting, the device is controllable starting. When the power suddenly off, it can ensure the electrical and mechanical equipment smoothly slow down, so it confirm the safety. This product is digestion a number of new technology: It selects resist high pressure, high temperature, corrosion, the imported longevity friction sheet. We developed the board of small brake can be passed to his matrix. All the products passed balancing test before delivery. The product has passed national coal safety certification and it has very high performance of the explosion-proof and reliability.
