The synchronization gear pump can reduce the radial and boost the work pressure.

同步齿轮泵能够降低齿轮泵径向力，提高齿轮泵的工作压力。

So hydraulic press driven by pump-accumulator can boost pressure more quickly than driven directly by pump, but the work is equal when the two types of presses make work pieces deformed.

因此，它比泵直接传动的压机升压快，但是在使工件产生变形时作的功都是相等的。
