标准范围

所考虑的泵在大气压力下排放气体,并在一个阶段内达到小于100 Pa的极限入口压力。所采用的方法是,在指定温度下,在连接到泵进口的指定形式的试验穹顶中测量极限压力。

The considered pumps discharge the gas against atmosphere pressure and achieve a limiting inlet pressure of less than 100 Pa in one stage. The method adopted is that the ultimate pressure is measured at a specified temperature in a specified form of test dome attached to the inlet of the pump.
