Efficient and energy-saving petroleum-pumping device

Abstract

The invention provides an efficient and energy-saving petroleum-pumping device, and belongs to a petroleum production device. An electromagnetic coil of the efficient and energy-saving petroleum-pumping device is fixed outside an oil pump shell. A protective shell is fixed to the oil pump shell. An annular floating body is fixed to the lower face of the protective shell. A filter is fixed to an oil inlet in the lower end of the oil pump shell. An oil outlet valve is fixed into a central hole of the oil pump shell. An iron core spring and a magnetism-induced piston are arranged in the oil pump shell. The iron core spring is pressed on the lower end face of the magnetism-induced piston. A petroleum inlet channel of an oil inlet cavity is sealed by a sealing plate. A petroleum inlet channel of a squeezing cavity is sealed by a sealing ball or sealing cone. A fixing plug is fixed into a plug hole in the magnetism-induced piston. A sealing ball or sealing cone is installed in an inner conical hole. The efficient and energy-saving petroleum-pumping device is compact in structure, small in vibration, high in electric energy utilization rate, strong in power, high in petroleum pumping efficiency and suitable for pumping petroleum in a petroleum well and pumping petroleum in a petroleum sedimentation tank; when petroleum is pumped, sediment and moisture do not enter an oil pump; and petroleum can be conveyed in an automatic flowing manner after a power supply is turned off, and electric energy is saved.

Description

technical field [0001] The invention relates to the technical field of oil exploitation, in particular to an efficient oil extraction energy-saving device used for extracting oil in oil wells and oil sedimentation tanks, which can float on the oil surface. Background technique [0002] The traditional method of extracting oil in an oil well is to use a rocker piston lifting method to extract the oil in the oil well. During the pumping process, due to the large vibration and the fact that the oil inlet pipe for pumping oil is inserted into the bottom of the oil well, the extracted oil has relatively heavy sediment and water content. The oil pumps in traditional petroleum sedimentation tanks are all installed at the bottom of the sedimentation tank or in the pipeline near the bottom of the sedimentation tank. The oil-water separation in the sedimentation tank is to release the water at the bottom of the sedimentation tank before pumping oil, resulting in the oil pumped out by ...
