Detailed Description
In order to make the technical solution and the advantages of the present invention more clear and obvious, the present invention is further described in detail with reference to the following specific embodiments, it should be understood that the specific embodiments described herein are only used for understanding the present invention, and are not used for limiting the present invention, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.
FIG. 1 is a schematic structural view of an anti-corrosion and wear-resistant oil pump of the present invention, which comprises a casing 6, an oil pipe 4 and an oil pump main body 5, wherein the oil pipe 4 is arranged inside the casing 6, the upper end of the oil pipe is sealed by a circular plate fixing member 3, the top of the oil pipe 4 penetrates through the circular plate fixing member 3, the connecting flange 1 is welded by a flow sensor 2, the lower end of the oil pipe is sealed by an oil inlet thread groove 9, a sealed cavity is formed, an oil overflow hole 7 of the oil pump main body 5 is connected with the oil pipe 4, an oil inlet end 8 of the oil pump main body 5 is connected with the oil inlet thread groove 9, the oil inlet thread groove 9 is connected with an external filter head 10, the filter head 10 is in threaded connection with the oil inlet thread groove 9, a metal filter screen 11 is arranged in the filter head 10, oil through holes 12 are arranged on both sides of, and is fixed by a locking clamp 14, the locking clamp 14 being a retractable spring clamp.
Preferably, a plurality of metal anodes 13 are distributed on the outer walls of the oil pipe 4, the oil pump main body 5 and the oil inlet thread groove 9 at equal intervals.
The oil well pump main body 5 is controlled to carry out oil pumping operation, crude oil enters the filter head 10 from the oil through hole 12, the metal filter screen 11 in the filter head 10 can filter impurities in the crude oil, the oil well pump main body 5 can pump the crude oil filtered by the filter head 10 to a wellhead through the oil pipe 4, the oil pumping operation is completed, the metal anode 13 is arranged on the surfaces of the oil pipe 4, the oil well pump main body 5 and the oil inlet thread groove 9, so that the wear resistance and the corrosion resistance of the inner surface of the oil well pump main body 5 can be enhanced, and the phenomenon that the crude oil cannot be pumped and the loss is caused by the fact that bacteria and other corrosion factors can quickly corrode the inner surface.
Before the pump is started, the metal anode 13 is fixed by the locking clamp 14, and attention is paid to that the metal anode 13 and the outer walls of the oil pipe 4, the oil pump main body 5 and the oil inlet thread groove 9 cannot be painted and are in direct contact. Therefore, the metal anode 13 which is easy to lose electrons, the oil pipe 4, the oil pump main body 5 and the oil inlet thread groove 9 form a uniform electric conductor, and in the underground electrochemical corrosion environment, the metal anode 13 loses electrons firstly and is consumed, so that the oil pipe 4, the oil pump main body 5 and the oil inlet thread groove 9 are protected, and the purpose of corrosion resistance is achieved.
The electrochemical corrosion aims at protecting the whole oil well pump, so that the whole oil well pump can be protected no matter the oil pipe 4, the oil well pump main body 5, the oil inlet thread groove 9 or other parts in the oil well pump, the corrosion mainly occurs to the metal anode 13, and compared with a method adopting surface coating protection, the structure is more thorough and effective in protection.
