Melejchuk S. Working process and characteristics of vortex ejection stage for vacuum pump unit

Results of the working process and performance curves for vortex ejection stage of vacuum pump unit are given in this dissertation paper. It is determined an influence of the ejector internals geometry parameters on its characteristics. The main task of the study is to obtain design dependences of the components distribution in speed field of interacting flows on the base of the experimental data processing. It is demonstrated basic distinction in operation of vortex ejection stage of vacuum pump unit and autonomous operating ejector unit. Experimental part of study was shown the reception of expense features of components of vacuum unit (the of vortex ejection stage and liquid ring vacuum pump vacuum pump) depending on geometric correlation of running part an of vortex ejection stage. It is revealled that use an of vortex ejection stage allows to increase the range of functioning (working) the vacuum unit on pressure of suction and on threedementional capacity. Exergy analysis energy efficiency accounting schemes is organized. It is presented strategy of calculation of system of vacuum cooling the water solutions which allows to define the minimum volume productivity of the vacuum pump, and also to define time of cooling of a solution.
