一种新型的制动器用电力液压推动器

A New Type of Electric Hydraulic Driver for Brake

电力液压推动器主要依靠电力作为能源,常用作高速轴制动器的驱动装置。带式输送机用高速轴制动器如块式制动器和盘式制动器属于常闭型制动器,制动器开闸时要求电力液压推动器持续运行。当该种类型制动器用于带式输送机等连续运输设备时,随着运输设备的持续运行,电力液压推动器也必须连续通电且持续发热。使用一种新型液压推动系统来替代传统的电力液压推动器,这种新型液压推动系统具有保压功能,可解决推动器耗电和发热问题。

Electric hydraulic driver relies mainly on the power as an energy source,used to drive the high-speedshaft brake. The high speed shaft brakes,such as block brakes and disc brakes,are often closed type brakes forbelt conveyor. The power hydraulic propeller is required to run continuously when the brake is opened. When thetype brake is used for continuous transport equipment such as belt conveyor,the electric power hydraulic propellermust continuously pass through and continue to heat with the continuous operation of the transport equipment. Us-ing a hydraulic propulsion system to replace the traditional driver,this hydraulic propulsion system has the func-tion of maintaining pressure,which fundamentally solves the problem of power consumption and heating.
