    4、結(jié)構(gòu)及工作原理:

    Four、Structure and working principle:

         BEd系列電力液壓推動(dòng)器主要由隔爆電機(jī)、中間法蘭、葉輪、成套活塞等組成。接通推動(dòng)器電源,電機(jī)旋轉(zhuǎn)帶動(dòng)葉輪產(chǎn)生壓力油,推動(dòng)活塞及連桿向上運(yùn)行。達(dá)到預(yù)定行程后維持其推力。電源斷開(kāi),電機(jī)及葉輪停止轉(zhuǎn)動(dòng)不再產(chǎn)生壓力油,活塞及連桿在外力作用下恢復(fù)原位(見(jiàn)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)
