Самодействующие шаровые клапаны штанговых глубинных насосов

Abstract

The hydrodynamics of the self-acting spherical valve of socker rod pumping units used in petroleum production are considered in detail. The Magnus effect is described, which directly affects the operation of the suction and discharge valves, respectively, during the suction and discharge process. Geometrical relationships of the seat and small ball are determined, as well as the analytical dependencies of the dynamic forces at which the small ball is separated from the seat and placed into it. The phenomenon of delay in fit of a small ball in a seat is explained. Improved patented constructions of self-acting spherical valves are given.
