| Abstract: | In order to make clear the performance characteristics of offset structure and improve the design of reciprocating pumps, kinematic and dynamic analysis of offset slidercrank mechanism is made. The influence of the offset structure on stroke length, plunger suction and discharge rate and force transfer capacity of the connecting rod as well as the effect of crosshead on positive pressure of guide plate are analyzed. It is indicated that the force transfer capacity of the connecting rod can be improved and the crosshead positive pressure on the guide plate can be reduced by adopting the positive offset structure. |
