Cavitation in an Axial Piston Pump
Bulletin of JSME, 1983 In an axial piston pump made of acrylic resin, cavitation is observed by the naked eye with a strobo-scope and by high speed photography, and the pressure changes in the cylinder are measured. The cavitation is classified into the following two groups ; one, related to the trapping phenomenon, can be prevented by a suitable design of valve plates ...

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system
Deep Underground Science and Engineering, EarlyView.The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an
