- W2382131605 abstract "Be aimed at improving the efficiency of injector in mine automatic drainage system,the influence of control- valve on the process of injector vacuum- pumping was analyzed. Using the common DN25 mm injector which nozzle diameter was 8 mm as an example,the hydrodynamics software FLUENT was used to carry out simulation of internal flow field of injector with the different flow area of the control valve,and some experiments were done. From the analysis results,a conclusion could be got,when the control valve path area and nozzle path area ratio greater than 1. 5,vacuum pressure values for a longer time could be established; when the area ratio greater than 2,it would have a shorter time. This conclusion provides theory basis for the design of the control valve in the future." @default.
