| Abstract: | The existing problems on original kinematical analysis, on definition of Valve-Unseal-Delay angle, and on definition of Valve-Delay-Height of reciprocating pump valve were pointed out, also the analyses were made to find out the reasons. A study of kinematics of reciprocating pump valve was made with consideration of the Westphal phenomena, obtained the rule of height, velocity, and acceleration of the valve. The conclusions show that Westphal phenomena influences Valve-Seal-Delay Height, but has little effect on Valve-Unseal-Delay angle. |
