Abstract

The utility model provides an electromagnetic submersible pump which mainly solves the problems that the existing oil-pumping equipment has low efficiency and easy wearing. The electromagnetic submersible pump is characterized in that: the inner wall and the outer wall of the corresponding end of joints (1, 13) are connected with a piston wall (9) with a boss and a pump body (10) by screw threads; a direct current coil (7) is arranged between the upper part of the boss of the piston wall (9) and the pump body (10) at interval; the piston wall (9) is internally provided with a magnet (6), the upper end and the lower end of which are clamped by a magnetic sleeve (5) and the boss of a plug (8); the boss of the lower end of the magnetic sleeve (5) is connected with the plug (8) by screw threads; and the boss of the upper end of the magnetic sleeve (5) is fixed with a central valve sleeve (4). The submersible pump has the characteristics of high efficiency pump and long period of overhaul, is not easy to be worn and is not easy to be clamped by sands.

Description

A kind of electromagnetism oil-immersed pump

Technical field:

The utility model relates to a kind of oil field equipment, especially a kind of electromagnetism oil-immersed pump.

Background technique:

At present, the oil pumping common equipment that field produces is used has pumping unit, centrifugal oil-immersed pump and screw pump etc., though pumping unit has long operational time, pump efficiency advantages of higher, has shortcomings such as facility is huge, sucker rod is easily broken, mechanical efficiency is low; Though centrifugal oil-immersed pump has big, the fuel-displaced advantage such as continuously of discharge capacity, has shortcomings such as pump efficiency is low, the repair cycle is short; Go out the wet goods advantage continuously though screw pump has, have shortcomings such as easy to wear, Yi Shaka, sucker rod be easily broken.

The model utility content:

In order to overcome the deficiency of above-mentioned pumping unit, the utility model provides a kind of electromagnetism oil-immersed pump, and this oil-immersed pump has pump efficiency height, long, not easy to wear, difficult husky characteristics of blocking of repair cycle.

The technical solution of the utility model is: a kind of electromagnetism oil-immersed pump, comprise upper and lower joint, the pump housing, the corresponding end inside and outside wall of upper and lower joint the be threaded piston wall and the pump housing of boss, gap between the piston wall boss top and the pump housing is equipped with dc coil, piston wall is built-in with upper and lower end by the magnet of magnet sleeve and the clamping of plug boss phase, the magnet sleeve lower end boss plug that is threaded, valve sleeve pipe during magnet sleeve upper end boss is fixing.

The utlity model has following beneficial effect: owing to take such scheme, this oil-immersed pump moving element is little, its total mechanical efficient height; This oil-immersed pump pump housing is connected with upper and lower joint by screw thread, and outer surface is an integral body, makes its Nai Shaka, anti-obstruction under the bad working environments of down-hole; Because of its no high-speed rotary part, therefore not easy to wear, the repair cycle is long.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

1-upper connection among the figure, the last valve of 2-, valve among the 3-, valve sleeve pipe among the 4-, 5-magnet sleeve, 6-magnet, 7-dc coil, 8-plug, 9-piston wall, 10-pump housing, 11-seal ring, valve under the 12-, 13-lower contact.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By shown in Figure 1, a kind of electromagnetism oil-immersed pump, comprise joint (1,13), the pump housing 10, the corresponding end inside and outside wall of joint (1,13) the be threaded piston wall 9 and the pump housing 10, and seal ring is installed in the joint, guarantee sealing, there is boss at piston wall 9 middle parts, and the bottom contacts with the pump housing 10, make piston wall 9 bottom thickness thicken, more wear-resisting, gapped between the boss top and the pump housing 10, this gap is built-in with dc coil 7, by being located at ground rectifier Ac is become direct current, lead on the dc coil 7, and the periodically-varied current direction; Piston wall 9 is built-in with upper and lower end by the magnet 6 of magnet sleeve 5 and plug 8 boss phase clampings, the magnet sleeve 5 lower end boss plug 8 that is threaded, valve sleeve pipe 4 during magnet sleeve 5 upper end boss are fixing; Valve 2 during middle valve sleeve pipe 4 tops are fixing, the piston that magnet 6, magnet sleeve 5, plug 8, middle valve 3 and middle valve sleeve pipe 4 compositions can move up and down can move up and down along piston wall 9 in piston wall 9; Upper and lower joint (1,13) inside is fixed upper and lower valve (2,12) respectively.

During the utility model work, dc coil 7 provides the direct current of periodically-varied current direction, make magnetic direction periodically-varied in the piston wall 9, by magnet 6, magnet sleeve 5, plug 8, middle valve 3 and in the piston formed of valve sleeve pipe 4 under the effect of alternating magnetic field, can move up and down.When piston moved upward, middle valve 3 was closed, and following valve 12 is opened, and well liquid enters the pump housing 10, and simultaneously, last valve 2 is opened the well liquid more than the pump housing inner carrier is risen in the oil pipe; Dc coil 7 changes current direction then, and piston moves downward, and middle valve 3 is opened, and upper and lower valve (2,12) is closed, and piston moves to the pump housing 10 bottoms by the pump housing 10 tops.To-and-fro motion thus can constantly be promoted to well liquid in the oil pipe.This oil-immersed pump moving element only has piston, and quality, volume are little, its total mechanical efficient height; The pump housing 10 connects by screw thread and upper and lower joint (1,13), and outer surface is an integral body, makes its Nai Shaka, anti-obstruction under the bad working environments of down-hole; Because of its no high-speed rotary part, therefore not easy to wear, the repair cycle is long.

Claims

1, a kind of electromagnetism oil-immersed pump, comprise joint (1,13), the pump housing (10), it is characterized in that: joint (1,13) the corresponding end inside and outside wall piston wall (9) and the pump housing (10) of boss that be threaded, gap between piston wall (9) the boss top and the pump housing (10) is equipped with dc coil (7), piston wall (9) is built-in with upper and lower end by the magnet (6) of magnet sleeve (5) and the clamping of plug (8) boss phase, magnet sleeve (5) the lower end boss plug (8) that is threaded, valve sleeve pipe (4) during magnet sleeve (5) upper end boss is fixing.
