1、升降舞台http://www.iyunsun.com/电磁换向阀液压控制系统：按动电动机开关，油泵打油次时油泵处于卸荷状态，按起动开关，液压升降机起升。按下降开关，升降舞台依靠自重下降到原始位置。
Landing stage solenoid valve hydraulic control system: Press the motor switch, buy oil pump oil pump in unloading times, press the start switch, hydraulic lift lifting. Press the down switch, lift the weight down to the stage to rely on the original location.
  
2、升降舞台液压控制系统： 增加一套备用的手动泵，以备在无电源的情况下使用。使用手动泵时首先将回油阀旋钮按顺时针方向拧紧，压动手柄升降舞台便可起升，下降时松开回油阀旋钮升降舞台靠自重下降。
Landing stage hydraulic control system: increase a spare hand pumps, ready for use in the absence of the power supply situation. When using the hand pump first oil return valve knob clockwise to tighten the landing stage can handle the pressure moving lifting, loosen the oil return valve knob landing stage falls drop by gravity.
  
3、升降舞台http://www.iyunsun.com/支撑阀控制液压系统： 启动电动机开关，电机旋转，齿轮泵打油，油缸伸出，升降舞台起升；待升到工作所需高度时，按电机停止按钮，升降舞台停止升降，即可作业，下降时，按电磁铁接通按钮，此时油缸回油接通，升降舞台靠自重下降，带降到原始位置后，关闭电磁铁。
Landing stage hydraulic valve control system support: Start the motor switch, motor rotation, gear pumps Dayou, cylinder extends landing stage lifting; when the work needed to be raised to the height of the motor press the stop button to stop the lift landing stage, you can work after, when dropped, the electromagnet on button, then turned back to the oil tanks, landing stage by gravity drop down with the original location, close electromagnet.
