【摘要】 水力空化装置是利用水力空化技术的关键.通过利用几种不同的多洞孔板对水力空化装置的试验研究,结果表明:在水力空化系统中,增大孔板的进口压力,可以增加孔板流量,从而提高孔内的平均流速,降低空化数;由于孔板的作用,系统中的水温上升率要比没有安装孔板的系统大;并分析得出孔板下游恢复压长度为4倍管直径.更多还原

【Abstract】 It is key that equipment of hydrodynamic cavitation to make use of the hydrodynamic cavitation technique.Through trial research to equipment of hydrodynamic cavitation by making use of a few different multiple hole orifice plates,the result enunciated: in hydrodynamic cavitation system,enlarge the inlet pressure of multiple hole orifice plates,it can increase the discharge of multiple hole orifice plates,thus raise the average flow velocity in the hole,lower to cavitational number;Because of the function of the orifice plates,the water temperature in the system rising rate needs to compare and did not install the orifice plates system big;Analytical at the same time a orifice plates downstream recovered pressure the length to 4 the tube diameter.更多还原
