Efficient and energy-saving device for pumping oil

Abstract

The invention discloses an efficient and energy-saving device for pumping oil and belongs to oil production devices. An electromagnetic coil of the efficient and energy-saving device for pumping oil is arranged outside an oil pump shell. A protection shell is fixed to the oil pump shell. An annular floating body is fixed below the protection shell. A filter is fixed to the position of an oil inlet hole in the lower end of the oil pump shell. An oil outlet valve is fixed in a center 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 magnetism-induced piston. An oil inlet channel of an oil inlet cavity is sealed through a sealing cap, and an oil inlet channel of an extrusion cavity is sealed through a sealing plate. A fixed stopper is fixed in a piston hole in the magnetism-induced piston. A sealing ball or a sealing cone is installed in an inner cone hole of the magnetism-induced piston. A containing hole is formed in the lower end of the magnetism-induced piston. The efficient and energy-saving device for pumping oil is compact in structure, low in vibration, high in electric energy utilization rate, high in power, high in oil pumping efficiency and suitable for pumping oil in an oil well and pumping oil in an oil setting pond; sediment and water cannot enter an oil pump during oil pumping; and oil can flow automatically to be conveyed, and electric energy is saved.

Description

Technical field [0001] The present invention relates to the technical field of petroleum exploitation, in particular to a high-efficiency and energy-saving equipment for pumping petroleum from petroleum wells and petroleum sedimentation tanks that can float on the petroleum surface. Background technique [0002] The traditional extraction of oil from oil wells uses rocker piston lift to extract oil from the well. In the process of extraction, due to the large vibration and the insertion of the oil inlet pipe to extract the oil into the bottom of the oil well, the extracted oil has a heavier sediment and moisture content. The oil pumps in the traditional oil sedimentation tank are 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 discharge the water at the bottom of the sedimentation tank before pumping oil, resulting in the oil pumped by the oil pump There is mo...

AI Technical Summary

Problems solved by technology

The oil pumps in the 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 the oil pump. moisture or impurities
