1、概述

1, overview

 

    BEd系列隔爆型电力液压推动器(以下简称“推动器”)主要适用于操作电力液压鼓式制动器及操动唧筒、棘轮、阀等,还可操动各种形式的杠杆装置,作出各种不同的运动,如往复、摇摆、圆周运动等,

    Bed series flameproof type electric hydraulic driving device (hereinafter referred to as the "driver") is mainly suitable for operating electric hydraulic drum brakes and actuating pump, ratchet, valve, operating various forms of leverage device, make different kinds of sports, such as reciprocating swing, the circle movement,

 

    本产品执行企业标准Q/JZHF01-2009隔爆型电力液压推动器技术条件。防爆标志为“ExdⅠ ”,适用于煤矿带式输送机(非采掘工作面)及矿井提升设备等用电力液压鼓式制动器用的电力液压推动器。

    The product implementation enterprise standard Q/JZHF01-2009 flameproof type electric hydraulic driving device technical conditions. Explosion proof mark Exd I for, used in coal mine belt conveyor mining working face and mine lifting equipment with electric hydraulic drum brake with electric hydraulic driving device.

 

    推动器是实现某些机械设备半自动化、自动化的理想元件,活塞杆采用先进的防护,可减少磨损和腐蚀,有双层防护密封、液压系统的油腔采用双层密封圈,从而大大提高了推动器的使用寿命,该推动器具有动作平稳无噪音,耗电少,使用寿命长,维修方便等优点。

    Drive is some machinery and equipment to achieve semi automation, automation components, piston rod adopts advanced protection, reducing wear and corrosion, double door seal, oil chamber of the hydraulic system using double sealing ring, thus greatly improving the promote the service life of the machine, the drive has the movement to be smooth, no noise, low power consumption, using the advantages of long service life, convenient maintenance and so on.2、工作条件

4、结构及工作原理:

FourStructure and working principle:

     BEd系列电力液压推动器主要由隔爆电机、中间法兰、叶轮、成套活塞等组成。接通推动器电源,电机旋转带动叶轮产生压力油,推动活塞及连杆向上运行。达到预定行程后维持其推力。电源断开,电机及叶轮停止转动不再产生压力油,活塞及连杆在外力作用下恢复原位(见图一)

     Bed series power hydraulic pusher is mainly composed of flameproof motor, composed of intermediate flange, impeller, a complete set of piston. Connect the drive power supply device, the motor rotates and drives the impeller produces oil pressure, promote the piston and connecting rod to run. After reaching the scheduled trip to maintain the thrust. To disconnect the power supply, electric motor and impeller stops rotating no longer produce pressure oil, the piston and connecting rod under the external force recovery in situ (see photo)
