Abstract

The invention provides a well electric hydraulic conversion high-lift plunger pump. According to the technical scheme, the well hydraulic conversion high-lift plunger pump is mainly composed of a cylindrical pump A (1), an A pump liquid outlet (2), an A pump liquid flow pipeline (3), an A pump work cavity (4), an A pump plunger (5), an A pump reversing valve (6), an A pump drain valve (7), a cylindrical power liquid tank (8), a power liquid pipe (9), a first power liquid pipe opening (10), a cylindrical pump B (11), a B pump plunger (12), a B pump shaft (13), a coupling device (14), a cylindrical motor (15), a motor shaft (16), a first connecting mechanism (17), a B pump plunger drive plate (18), a B pump oil distributing disc (19), a second connecting mechanism (20), a second power liquid pipe opening (21), a third connecting mechanism (22), an A pump liquid inlet valve (23), an A pump power liquid pipeline (24) and an A pump work liquid inlet (25). The well electric hydraulic conversion high-lift plunger pump is reasonable and practical in design, the problem of eccentric wear of a rod pipe is basically solved, the service life of an oil pipe is effectively prolonged, high efficiency and low consumption are achieved, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of plunger pumps, in particular to an electric-hydraulic conversion high-lift plunger pump for wells. Background technique [0002] At present, in the field of oil field development and extraction technology, the main application of mechanical production equipment is various rod pumps and tube pumps that need to be equipped with surface pumping units, screw pumps that need to be equipped with oil rods and surface motor reducers, and rodless submersible oil pumps. electric pump etc. These equipments have been leading the development and production of oilfields, but the defects of these equipments affect the development of oilfield development technology and the further improvement of mining benefits. Ground pumping units are huge in equipment, high in procurement costs, complex in structure, and time-consuming to maintain and repair. In the process of converting the rotational motion of the motor into the re...
