只要阀门关闭效果良好，保压时，高压截止阀关闭，后端压力容积变小，压力增大。

As long as the valve closure effect is good, when the pressure, high pressure cut-off valve is closed, the back-end pressure volume smaller, pressure.

功率的选型是在满足工作压力和容积流量的条件下，供电容量能满足所匹配驱动电机的使用功率即可。

The power of the selection is in meet the job pressure and volume flow conditions, power supply capacity that can satisfy matching the use of driving motor power can.

在操作前，必须对压力极限、系统容积、净化要求等专门考虑，以决定是否要求额外的安全措施。

Before operation, special consideration must be given to pressure limitations, system containment, purging requirements, etc., to determine if additional safety measures are required.

This piston is being brought out, so we expect 0 the work to be negative, negative. And we start o V2 ut with zero volume. We end up with a volume p2 of V2, and the external pressure is constant to p2.

所以我们可以想象功是负的,开始的时候体积是,最终的容积是,外界的压力恒为。

V2 And there's going to be some volume V2 and some volume V1, but are not necessarily the same. Especially since the pressures are different. we don't know yet about temperature so I don't know what to say about these volumes because I don't know what the temperatures' are going to do.

这里的体积会变成2,这里的容积是V1，它们不必相等,尤其是当压力不相等的时候,我们还不知道温度,所以我不能说这里的容积,是多少因为我不知道,温度会怎样变化。
