五、注操作方法
V. Operation Method
1、根据液压原理图，用清洁的油管将液压动力单元与油缸连接起来。
1. Please connect the hydraulic power unit with the reservoir using clean oil
pipelines.
2、根据电机与电磁阀标示的电源特性（交流，直流）电压正确连接。
2. Please connect the motor with the electromagnetic valve in a proper manner.
And ensure that they allows the same kind of current(alternative or direct) and the
same voltage.
3、点动电机，观察有无异常现象。在执行元件，不加载情况下，启动电机，作空运行试验，
检查各零部件是否运行平稳，确定无误后，再逐步加载至正常运行。
3. Please turn on the motor to observe if there is anything abnormal. Please turn on
the motor without loading actuators to do a dry running and check if all the parts
are running smoothly. If everything is OK, then load them step by step till they
function normally.
六、注意事项
VI. Caution
1、本厂出品的液压动力单元出厂时，系统压力已调定。如需改动，用户根据实际情况自行
通过调压阀旋钮调整系统压力，但不能超过系统公称压力。
1. The system pressure of our hydraulic power units has been set prior to their
shipment. You could adjust system pressure via adjusting the pressure regulating
valve according to your needs, but the pressure should never exceed the nominal
pressure of the system.
2、认真检查电机及电磁阀接线情况，严禁虚接。
2. Please carefully check if the motor and the electromagnetic valve are properly
connected. Virtual connection is prohibited.
3、在第一次安装调试时，要注意保持油箱内部油位，经过一个工作循环后，应将油箱补足
油，但不能加的过满。
3. The reservoir shall maintain an adequate load of oil during the initial installation
and trial run. The reservoir shall be replenished at the end of a work circle but it
shall not be overly filled.
