Название (рус.): | Насосы вакуумные паровые. Измерение эксплуатационных характеристик. Часть 2. Измерение критического обратного давления |
Название (англ.): | Vapour vacuum pumps; measurement of performance characteristics; part 2: measurement of critical backing pressure |
Описание (англ.): | 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. |
