Studies on operation and types of drilling pump valves

The current issue of the machine building industry is improvement of oil and gas production equipment performance. However, despite the improved design and technological parameters, its reliability is still low. The time between failures depends on both severe operating conditions and quality characteristics of parts. With an increase in drilling depths, complexity of operating conditions and abrasiveness of the drilling mud, the life time of the hydraulic part of the pump decreases. Operation of drilling pumps largely depends on the design features of the valves. According to the results of theoretical studies, wear of the valve pair occurs on the bearing surface. The design of valves with different seating surfaces and shapes of the sealing element was studied. Based on the research on the improvement of the drilling pump valves, the conclusions were drawn and the tasks for further research were formulated.
