传统的往复活塞式泥浆泵,都程度不同地存在着怕沙、易损件较多、流量时有降低且不易控制等问题。存在这些问题的关键原因是皮碗与缸壁有相对运动。为了解决这些问题,我们研制成功了不怕沙子的泥浆泵(定名为不畏沙式泥浆泵)及其附属机构变量开关,并荣获了河南省重大科学技术成果奖。这种 The traditional reciprocating piston mud pump, there are varying degrees of fear of sand, wearing parts are more, when the flow rate is reduced and not easy to control and other issues. The key reason for these problems is the relative movement between the cup and the cylinder wall. In order to solve these problems, we successfully developed the sand pump (named as sand pump) and its affiliated agencies variable switch, and won the Henan Province Major Science and Technology Achievement Award.
