Design of skid-mounted power pack of five-cylinder slush pump;

Application and analysis of surface engineering technology on drilling pump liner;

Wear-resistance of the drilling pump liner in oil industry is one of the key factors to the service life.

The surface of 45 steel drilling pump liner was modified by plasma spraying and the ceramic coating of the liner was prepared.

This paper studies the steadystate motion law of triplex drilling pump with friction considered.

Rational matching of n/S of a triple cylinder single action drilling pump;

The experimental study shows that the parameters on the fracturing truck with quintuple pump are obviously superior to the ones on the fracturing truck with triplex pump.

Testing method of the impacting force of drilling pump valve in the course of valve closing;

In view of the characteristic of severe erosion and abrasion in the drilling pump valve,the flow field of the play of it by FLUENT was simulated and computed in this paper.

According to the impact fatigue failure appeared in drilling pump valve,the mechanical characteristic and effect degree of the maximum stress concentration spot when the impact of pump valve happens were mainly studied,hence a non-impact working condition of drilling pump valve based on the effects of stress concentration was put forward.
