Abstract：With respect to the problems of the high and low pressure alternating fatigue failure of cylinder body and chloride ion strong corrosion existing in the high pressure water injection pump for oilfield,the structure and optimum design of parameters of high pressure reciprocating type water injection pump for oilfield are introduced in this paper.By a new type design structure for fluid end and power end of high pressure reciprocating pump with combination valve,bidirectional combined seal,inverted lubrication mode and new corrosion-resistant material the key technical problem of reliability for high pressure water-injection pump is solved.Test results show that the speed of high pressure plunger type water injection pump is reduced by about 30%~50%,even under aggressive operating conditions,the reliable operating cycle of high pressure water injection pump for oilfield can be greatly improved.
