ISO 1608-2:1989 蒸汽真空泵.性能特性的测量.第2部分:临界前级压力的测量

标准编号:ISO 1608-2:1989

中文名称:蒸汽真空泵.性能特性的测量.第2部分:临界前级压力的测量

英文名称:Vapour vacuum pumps — Measurement of performance characteristics — Part 2: Measurement of critical backing pressure

发布日期:1989-12

标准范围

所考虑的测量方法涉及蒸汽喷射真空泵、扩散泵和扩散喷射泵。这些泵的性能对背压的依赖性只能通过运行范围内的进口和背压曲线来完全描述。介绍了推荐的试验穹顶和试验设备的原理。

The considered method of measurement deals with vapours jet vacuum pumps, diffusions pumps and diffusion-ejector pumps. The dependence of the performance of these pumps on the backing pressure can only be completely described be means of a curve relating the inlet and backing pressure over the range of operation. The recommended test dome and the principle of the test equipment are illustrated.
