| Abstract: | According to the mechanism of pump with top clearance plunger,this paper analyzed all factors that influenced the consistency of pump running.It's found that all factors that influence the variation of plunger cavities' pressure will affect the consistency of plunger.Discussions among these factors including precision of product design and process,sealing of matching parts and opening pressure of delivery valve etc,were performed,and then,respective solutions were figured out.Consequently,all these works provided guidance for improvements on pump consistency. |
