Example Embodiment

[0012] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0013] like figure 1 , 2 As shown in the figure, the screw type oil pumping device of the present invention includes an oil pumping drum 1 with two ends open, and an oil extraction unit 2 is installed in the oil extraction drum 1 along the axial direction. The drive motor 21 and its output shaft 22 installed at intervals and coaxial with the oil sucking drum 1, and the helical fins 23 arranged on the output shaft 22; and the output shaft 22 and the helical fins 23 extend to the oil sucking A check valve 3 is also installed at the oil outlet port of the oil pumping drum 1 .

[0014] Specifically, the oil sucking drum 1 is provided with several radial screw holes 10 , and each radial screw hole 10 is provided with a fixing bolt 11 for positioning the driving motor 21 , that is, the fixing bolt 11 extends from the radial screw hole 10 . 10 penetrates...

Abstract

The invention relates to a spiral oil pumping device. The device comprises an oil pumping barrel with openings at the two ends, wherein an oil production machine is axially installed in the oil pumping barrel and comprises a drive motor, an output shaft of the drive motor and spiral fins arranged on the output shaft; the drive motor and the output shaft are installed at intervals with the inner wall of the oil pumping barrel and are coaxial with the oil pumping barrel; and a check valve is also installed at the oil outlet of the oil pumping barrel. The device has the following beneficial effects that: the drive motor is utilized to drive the spiral fins on the output shaft of the drive motor to rotate, thus transporting the oil from the oil inlet to the oil outlet via the gap between the drive motor and the inner wall of the oil pumping barrel and ensuring the oil to flow into the oil pipeline after the check valve at the oil outlet of the oil pumping barrel is pushed open by the oil pressure so as to achieve the aims of oil pumping and transport; and the device has a small overall volume and low manufacturing and use costs, can be used in combination with the solar or wind power supply equipment, without other energy consumption, is convenient to use, has high flexibility, can be butt-jointed for relay oil transport and can be used for long-distance oil transport to increase the oil transport pressure.

Description

Technical field: [0001] The invention relates to the technical field of oil extraction equipment, in particular to a screw type oil pumping device. Background technique: [0002] In the oil wells in the existing oilfields, the oil pumping units are all derrick type, commonly known as kowtow machine. The operation method is reciprocating vacuum oil pumping. This method requires great power to drive the swing arm movement, and the wear and tear is very large. , the consumption of consumables is many and expensive, so the cost of oil production is high. Moreover, due to its large size and weight, it is very inconvenient to move and install such oil extraction equipment. If it is in a relatively remote area, it needs to be equipped with a diesel generator to drive its operation, which not only consumes high energy, but also is not environmentally friendly. . Invention content: [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of th...
