Abstract
The utility model relates to an integrated high magnetic field wax prevention device, which is composed of the components of a casing, a permanent magnet, a soft magnet, a protective cover, an upper cover, etc. A homopolar and opposite arranging manner is adopted on a semicircle arranged at the inside of the casing of the permanent magnet, one layer of soft magnet is added between each layer of permanent magnet in order to form accumulation type magnetic field, and the magnetic field strength can be enhanced more than 15000 gauss. The wax prevention effect can be enhanced. The utility model has the advantages of simple structure, easy manufacture, reliable performance, long service life, light weight and low cost. The utility model is suitable for the wax prevention action in an oil pumping system in oil fields.
Description
The utility model relates to a kind of accumulation formula highfield wax control device, belongs to the parts that crude oil is extracted in the oil field.
Existing wax control device mainly be to adopt symmetric magnetic field to distribute, so field intensity is low, generally below 5000 Gausses, and the paraffin removal weak effect, maintenance cycle is short, and poor sealing performance is withstand voltage low, and below 5MPa, influence is produced, the cost height.
The purpose of this utility model provides a kind of accumulation formula highfield wax control device, it adopts the mode that magnet accumulation formula is arranged to improve magnetic field intensity and magnetic field gradient, field intensity is increased to more than 15000 Gausses, good uniformity, make the paraffin removal effect improve 3-5 doubly, the withstand voltage 45MPa that reaches, maintenance cycle improves more than 5 times.The manufacturing simple in structure, in light weight, easy of this wax control device, cost is low, the life-span is long, efficient is high, good seal performance.
The purpose of this utility model is achieved in that in the wax control device soft magnetic bodies half is arranged by the N utmost point with magnet steel on week in the garden, second half is pressed the S utmost point and arranges, make an interior existing parallel field, perpendicualr field is arranged again, and between two magnetic links, increase by a soft magnetic materials, to increase the accumulation of magnetic field intensity, be about to original symmetric magnetic field and change accumulation formula high-intensity magnetic field into, magnetic field intensity improved more than the twice more originally, and wax control result is greatly improved.
Concrete structure of the present utility model is provided by following examples and accompanying drawing:
Fig. 1 is the section of structure that the utility model is built up formula highfield wax control device.
Fig. 2 is the magnetic patch arrangement transverse cross-sectional view that the utility model is built up formula highfield wax control wax device.
Wax control device provided by the utility model waits other to form by parts by housing (1), permanent magnet (2), soft magnetic bodies (3), protective cover (4), loam cake (5).Permanent magnet (2) and soft magnetic bodies (3) layering in housing (1) are alternately packed into, and permanent magnet (2) is that homopolarity is assembled relatively on per half garden in housing (1), constitutes accumulation formula highfield simultaneously with soft magnetic bodies (3).After the overall package, shape half garden, field, magnetic field is the S utmost point, and half garden is the N utmost point, has formed the parallel magnetic field of high field intensity in housing (1).
It is strong magnetic material that the utility model is built up the interior used permanent magnet of formula highfield wax control device, and its shape can be fan-shaped, trapezoidal, polygon, and every layer can be one or more.
The utility model build up the housing of formula highfield wax control device and loam cake all adopt in, the mild steel manufacturing, and heat-treat.
The soft magnetic bodies that the utility model is built up formula highfield wax control device adopts cobalt steels or electrical pure iron manufacturing; Protective cover aluminium, stainless steel, titanium alloy, plastics or other nonmagnetic substance.
Claims (4)
1, a kind of accumulation formula highfield wax control device, form by other parts such as housing, permanent magnet, soft magnetic bodies, protective cover, loam cake, it is characterized in that permanent magnet adopts homopolarity to arrange relatively on per half garden vertically in housing, between each piece permanent magnet sheet, added one deck soft magnetic bodies, to form accumulation formula magnetic field.
2, accumulation formula according to claim 1 highfield wax control device is characterized in that permanent magnet radially adopts heteropole to arrange relatively on per half garden in housing, to form parallel magnetic field.
3, according to claim 1 and 2 described accumulation formula highfield wax control devices, it is characterized in that permanent magnet adopts strong magnetic material, the shape of permanent magnet can be fan-shaped, trapezoidal, polygon, every layer half garden can be one or more combination.
4, according to claim 1 and 2 described accumulation formula highfield wax control devices, it is characterized in that housing and loam cake all adopt in or the manufacturing of mild steel high-strength material; Soft magnetic bodies adopts cobalt steels or electrical pure iron manufacturing; Protective cover is made with aluminium, stainless steel, titanium alloy, plastics or other nonmagnetic substance.
