摘　　要：介绍了钻孔水力采矿射流水枪试验台的设计原理 ,在该试验台上可以模拟水枪在大气中的自由射流、模拟无压流体淹没条件下的射流以及模拟有压流体淹没条件下的射流等。设计的测试系统能对水枪射流能力、不同喷距下的射流打击力、流体流量、压力等参数进行测试。可以准确地衡量不同喷嘴、不同喷距。This paper presents the design principle of the experimental bench of the squirt gun used in borehole hydraulic mining. The free jet current out of the squirt gun in the atmosphere, the submerged jet current of the liquid without or with pressure are simulated on the experimental bench. The testing system can measure the jetting capacity of the squirt gun, hitting power of ejecting current, liquid flux and pressure. It can also precisely judge the impact of the ejecting current with different nozzle, different jetting distance and different working condition.
