简介General Description                   

此液压动力单元专为登车桥设计，由高齿轮油泵、直流电机、多用集成块、各式液压阀、油箱等零部件有机组合为一体。主甲板上升到位后，唇板自动上升，主甲板和唇板的下降由电磁阀实现，主甲板和唇板的下降速度由节流阀调节，使下降速度在可靠的范围内。

This power unit is designed exclusively for the dock leveler,consisting of high pressure gear pump, DC motor, multi-functional manifold,valves and tank.etc.After the main platform is fuily lifted, lip rises automatically.The both lowering movements are activated by the solenoid valves with speed adusted by the throttles.

注意事项Special Notes                  

1.此动力单元不可连续运转，（1分钟ON，9分钟OFF）可重复工作。

1.The power unit is of S3 duty,which can only be worked intermittentiy,ie.,1 minute on and 9 minutes off.

2.安装前必须保证油缸、油管、接头等液压元件清洁无任何杂质粘附。

2.Clean all the hydraulic parts concemed before mounting the power unit.

3.液压油粘度应为15-68CST，应清洁无杂质，推荐使用N46号液压油。

3.The viscosity of the oil shoud be 15-68 cst.

4.系统使用第一个100小时后，应更换液压油，以后每3000小时更换一次液压油。

4.Change the oil after the first 100 hours of using the power unit,then change the oil every 3000 hours.

5.首次启动运行系统时，应立即检查油箱中的油量是否充足。

5．Check the oil level in the tank after the first star of the power unit.
