乌拉尔重型机器制造厂曾对确定钻井泵泵阀弹簧的最佳性能进行了研究,以使阀在无冲击条件下工作时有最小的阻力损失H,从而通过阀隙的液流流速最小,减小阀盘与阀座的冲蚀磨损。
The Ural Heavy Duty Plant has studied the best way to determine the pump valve spring of a drilling pump so that the valve has the least resistance loss, H, when operating in a shockless condition so that the flow rate through the valve gap is minimized and reduced Erosion of disc and seat erosion.
