求翻译：工作油在泵涡轮间循环是靠两轮间滑差所产生的压差来实现，这就要求涡轮的转速要低于泵轮。是什么意思？

Working oil between the pump turbine cycle is the pressure generated by the two inter-slip, which requires the turbine speed is lower than the pump wheel.

The oil in the pump-turbine cycle is dependent on two-wheel differential between the pressure differential to achieve, and this will require that turbine is the speed to low to the pump.

The power oil the circulation is depends on the differential pressure in the pump turbine between which two turn between slippery difference produces to realize, this requests the turbine wheel the rotational speed to have to be lower than the pump pulley.

Working oil pump turbine cycle is produced by slip between the two rounds of the pressure to achieve, this requires the speed of the turbine than the pump.
