| Popis: | The oil vapout ejector operates under the delivery pressure of a few mm Hg and has a large pumping speed at the suction pressure of 0.01∼0.1 mm Hg. We have studied on this ejector for the purpose of obtaining data to be applied to its design. For the working fluid we have used the transformer oil. By the experiment, we have verified the existence of the so-called hysteresis phenomena in the oil vapour ejector as in the case of the steam ejector, and also we have studied the effects of some factors upon the pumping speed, that is the effects of the auxiliary pump, the pressure before nozzle, the relative position between nozzle and diffuser, the expansion ratio of nozzle and the cooling condition in diffuser and besides studied on the law of similarity. About the hysteresis phenomena we will report in the subsequent paper. |
