Development of hollow pump with top mounted ring shaped valve
摘要
Abstract
Hollow pump with top mounting ring shaped valve was designed because of subsurface pump's piston down going difficultly, the lower part of sucker rod deforming by pressure, and in order to overcoming eccentric wear of sucker rod and tubing as well.The ring shaped valve that was located in the upper part of normal subsurface pump could complete suction and flowing back by seating sealing and unsealing, at the same time it could realize loading heavy weight by passing through pump.The performance of sealing and unsealing of hollow pump was analyzed, and the prototype with CYB Φ44×5 type was prepared.The sealing performance and leakage of whose hollow pump all parts and whole structure were tested.The test results showed that the hollow pump with top mounting ring shaped valve had reasonable design and could meet operating requirements completely.关键词
