So even in the face of a complete station blackout—you don't have any power at all—there are methods for using the steam-drivenpump to continue to keep cooling going.
所以即使面临电厂断电——你无法获得任何电力——仍然有办法用蒸汽驱动的水泵来继续冷却系统运转。

In order to achieve power steering function in fuel cell bus, an electrohydraulic system is proposed, where the pump is directly driven by a DC motor through an axis coupler.
In the light of the key technique of the down-hole driven progressive cavity pump (PCP) for oil production, a power distributional planetary reducer is proposed.
