High-efficiency and energy-saving electromagnetic pump for oil pumping

Abstract

The invention discloses a high-efficiency and energy-saving electromagnetic pump for oil pumping and belongs to oil exploitation techniques. An oil pumping shell, an upper magnet and a lower magnet are installed in a buoyant shell of the high-efficiency and energy-saving electromagnetic pump. The upper magnet and the lower magnet are arranged on the upper side and the lower side of the outer surface of the oil pumping shell respectively. The lower end of the oil pumping shell is fixed to the lower end of the interior of the buoyant shell. An oil outlet valve is fixed a center hole of the oil pumping shell. An iron core piston is arranged in the oil pumping shell. An oil inlet channel of a sealing cavity and a squeezing cavity is sealed through a sealing cap. A limiting plug is fixed in a plug hole in the iron core piston. A sealing ball or a sealing cone is installed in an inner conical hole. A containing hole is formed in the lower end of the iron core piston. The high-efficiency and energy-saving electromagnetic pump for oil pumping is compact in structure, strong in power and suitable for pumping oil in an oil well and oil in an oil settling pond; the pump floats on the oil surface when used for pumping the oil and can rise or fall automatically along with the rising or falling of the oil surface, and silt and water at the bottom of the oil well or the settling pond are prevented from entering the oil pump; in addition, the oil can be delivered in a self-flowing mode after a power supply is cut off.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a high-efficiency and energy-saving electromagnetic pump for pumping petroleum in petroleum wells and petroleum sedimentation tanks and capable of floating on the petroleum 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...

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
