由于高压工况的特殊要求 ,浓稠泥浆的输送仍需由往复泵来承担。然而 ,在对系统进行一些小的改进例如增加管线的截面 ,减少管线的滑动摩擦之后 ,可以大大地降低压力等级 ,并且可以使用偏心螺杆泵 ,从而比容积式泵降低成本。针对这种“新的”应用 ,Wangen泵阐述了标准设计应如何加以修改 Due to the special requirements of high-pressure conditions, the transmission of thick mud still need to be borne by the reciprocating pump. However, after making minor improvements to the system, such as increasing the cross-section of the line and reducing the sliding friction of the line, the pressure level can be greatly reduced and eccentric screw pumps can be used, reducing the cost of the positive displacement pump. For this “new” application, Wangen Pump explains how the standard design should be modified
