【摘要】：水力引射器在煤矿井下引射泡沫剂、湿润剂等粘度较高的化学添加剂时,其引射系数与设计值的偏差较大。从水力引射器吸液段阻力与粘度、流动阻力损失对引射系数的影响等方面进行理论分析,并以清水和不同浓度泡沫添加剂为试验介质,开展了流体粘度对引射系数的影响试验,测试结果表明:理论计算和试验结果较为吻合,引射流体粘度对水力引射器引射系数的影响较大。可为面向高粘度引射流体的水力引射器的设计和使用提供参考。
[Abstract]:When hydraulic injector injects foam agent, wetting agent and other chemical additives with high viscosity in coal mine, its ejection coefficient deviates greatly from the design value. The influence of fluid viscosity on ejection coefficient was analyzed theoretically from the aspects of resistance and viscosity in the suction section of hydraulic injector, and the influence of fluid viscosity on ejection coefficient was tested with clear water and foam additives of different concentrations. The test results show that the theoretical calculation is in good agreement with the experimental results, and the injective fluid viscosity has a great influence on the ejection coefficient of the hydraulic injector. It can provide reference for the design and application of hydraulic ejector for high viscosity ejector.
