1、概述

1, overview

 

    BEd系列隔爆型電力液壓推動器(以下簡稱“推動器”)主要適用于操作電力液壓鼓式制動器及操動唧筒、棘輪、閥等,還可操動各種形式的杠桿裝置,作出各種不同的運動,如往復、搖擺、圓周運動等,

    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,

 

    本產品執行企業標準Q/JZHF01-2009隔爆型電力液壓推動器技術條件。防爆標志為“ExdⅠ ”,適用于煤礦帶式輸送機(非采掘工作面)及礦井提升設備等用電力液壓鼓式制動器用的電力液壓推動器。

    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.

 

    推動器是實現某些機械設備半自動化、自動化的理想元件,活塞桿采用先進的防護,可減少磨損和腐蝕,有雙層防護密封、液壓系統的油腔采用雙層密封圈,從而大大提高了推動器的使用壽命,該推動器具有動作平穩無噪音,耗電少,使用壽命長,維修方便等優點。

    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、工作條件

4、結構及工作原理:

Four、Structure and working principle:

     BEd系列電力液壓推動器主要由隔爆電機、中間法蘭、葉輪、成套活塞等組成。接通推動器電源,電機旋轉帶動葉輪產生壓力油,推動活塞及連桿向上運行。達到預定行程后維持其推力。電源斷開,電機及葉輪停止轉動不再產生壓力油,活塞及連桿在外力作用下恢復原位(見圖一)

     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)
