要对某一机械零件作出正确的失效分析,必须对其正常的工作特性有充分的了解。 泥浆泵液力端所以能泵送钻井所需的泥浆,是因为其泵腔的 体积随同活塞的进出而变更。图1是一个表明活寒和泵腔的示意 图。
To make the correct failure analysis of a mechanical part, it is necessary to have a full understanding of its normal working characteristics. Mud pump hydraulic end so it can pump drilling mud, because the volume of the pump chamber with the piston access to change. Figure 1 is a schematic showing live cold and pump chamber.
