为了解泥浆泵活塞在不同工作压力下,活塞密封区接触面积的大小和位置与泵压的关系,特做本试验,试验结果画出了关系曲线,同时也分析了活塞失效形式。进而提出活塞制造时,应有高、低压之分,分别用于高、低压工况;并对活塞的几何形状也提出些看法,为设计新型活塞提高活塞寿命无疑是很有益的。 To understand the mud pump piston at different working pressures, the contact area of ​​the piston seal area size and location of the relationship with the pump pressure, made this test, the test results draw the relationship curve, but also analyzed the piston failure form. Furthermore, the piston should be made when there should be high and low pressure points, respectively, for high and low pressure conditions; and the geometry of the piston also made some comments for the design of new piston piston life is undoubtedly very useful.
