液压传动具有工作平稳、易于实现自动控制的优点，因此橡胶注射成型机采用液压传动作为动力源。

Because hydraulic drive was even and easy to control, it was applied in rubber injection molding machines as power source.

由于动力源受制于环空压差，所以采用电机泵作为液压动力，电机泵由井下涡轮发电机供电。

Because the power is limited by the circulation pressure, therefor use the motor pump as the power of hydraulic, the power of the motor pump supply from the turbine generators underground.
