Description

A kind of process units of hot spraying alloy coating on surface of polished pumping rod
Technical field
The present invention relates to a kind of hot spray process device for alloy coating on surface of polished pumping rod, belong to the oil equipment field.
Background technology
In petroleum industry, the oil pumper sucker rod pumping is a kind of artificial lift oil production method, and is simple with its equipment, small investment, and convenient management, advantage such as compliance is strong is extensively adopted by each oil field both at home and abroad.Oil pumper, sucker rod and oil well pump are three chief components of sucker rod pumping equipment, and wherein sucker rod is the motion and the transmission of power of oil pumper are carried out pumping to downhole pump parts.Oil pumping polish rod is the different sucker rod of rod string top one Gent, be used for and well head seal box fitted seal mouth of pumped oil well, therefore condition of work is more abominable than sucker rod, except that the condition of work of sucker rod, oil pumping polish rod in the exposed atmosphere in the open air, is immersed in during down stroke in the well liquid when upstroke, therefore oil pumping polish rod both had been subjected to atmospheric corrosion, being subjected to the well corrosion again, also will not bearing high temperature when fuel-displaced, is the harshest different sucker rod of a Gent of condition of work.
For this reason, oil pumping polish rod being carried out surfacing is to prolong its application life the most effectively to handle means to improve its corrosion resistance and abrasion resistance.Surface treatment method commonly used at present comprises electrodeposited chromium, chemical nickel phosphorus plating and alloy coating hot-spraying technology.
The electrodeposited chromium technology is to plate one deck chromium topping on the oil pumping polish rod surface by plating; this case hardness height, highly polished, certain abrasion resistance and corrosion resistance arranged; slowed down the corrosion resistance of oil pumping polish rod to a certain extent; but because electrodeposited coating and matrix bond are not tight; tangible interface is arranged between electrodeposited coating and the matrix; it is very big that the composition of both sides, interface matrix and electrodeposited coating differs, and its chemical potential difference is also very big.In case surface electrical coating owing to hard particles for example the scuffing of sand grains defective appears, after causing the exposing of matrix, under electrochemical action, corrosion process can be that the interface is expanded rapidly along the position of potential difference maximum, finally cause the sheet of coating to peel off, cause the corrosion failure of oil pumping polish rod.In addition, the chemical nickel phosphorus plating technology also with the electrodeposited chromium technology type seemingly, nickel-phosphorus coating can sheet after the scuffing that is subjected to hard particles peels off, and causes the oil pumping polish rod corrosion failure.
The alloy coating hot-spraying technology is will have the alloy material spraying that anticorrosive wear-resistant decreases performance by plasma spray technology to be covered in the oil pumping polish rod surface, and make coating material and matrix material form metallurgical binding by remelting processing, the composition of coating and the composition of matrix be mutual scattering and permeating in reflow process, between coating and matrix material, there is certain thickness transition region, the composition that makes coating arrive matrix changes slow relatively, avoided the formation at the interface of composition sudden change, also problem with regard to having avoided chrome plating and nickel-phosphorus coating after defective appears in the surface, to cause the coating sheet to come off because of the expansion of corroding.
But, because alloy coating hot-spraying technology work flow relative complex, and oil pumping polish rod is typical ultra-fine stock class workpiece, and it is very high to cause that oil pumping polish rod is carried out surface heat spray process difficulty, does not therefore also have special alloy coating hot spray oil pumping polish rod production line.The present mode of production is that sucker rod hard surfacing equipment is carried out scrap build, the remelting that utilizes quenching apparatus to finish preheating to the body of rod, body of rod face coat is handled, and utilizes the thermal spraying treatment that abrasive band bistrique on the sucker rod hard surfacing equipment and flame heat spray spray gun are finished body of rod surface coarsening, coating polishing grinding and body of rod surface alloy coating that is placed in that increases in addition again.In addition, because sucker rod hard surfacing equipment is oblique roller nature supporting way to the supporting way of sucker rod workpiece, being about to the sucker rod free state is placed on a row and sucker rod axis and is on the roller that an angle places, utilizing frictional force to drive workpiece after roller rotates rotates on the one hand, move axially promptly spiral advancing on the one hand.Sucker rod in this process is because the size characteristics of its ultra-fine length and kinetic stability is very poor, beating degree is very high, has had a strong impact on the crudy of body of rod surface finish, coating hot-spraying.
Can realize the thermal spray process of either of the face coat of oil pumping polish rod though use the equipment of this transformation, but because the processing of each operation is all on same equipment, each operation is different to the requirement of equipment and workpiece, and is different to the influence of equipment and workpiece, the contradiction between the different process can occur.In whole process of production, the thermal spraying treatment of alloy coat and intermediate frequency remelting heat treated require very high to the precision of equipment and the smoothness of workpiece operation, in order to improve effect and the efficient that the intermediate frequency remelting is handled, heating in medium frequency coil distance body of rod surface distance is very little, generally be no more than 1cm, this just requires the beating degree of workpiece very little.On the other hand, when utilizing the abrasive band bistrique that grinding process is carried out on the polished rod surface, in order to guarantee certain polishing effect and grinding efficiency, bistrique can be very high to the following compressive load of the body of rod, this just causes workpiece stressed and vibration that the generation amplitude is very big in bruting process, and what cause that workpiece do not stop in traveling process beats, and very easily contacts and strike the heating in medium frequency coil, cause the damage of equipment, equipment failure rate is very high.
In addition, use this equipment can only carry out single and mini-batch production production, production efficiency is low; The multiple operation integrated equipment requires high to operator's operation, be prone to the human operational error, cause decrease in yield, these all greatly reduce the alloy coating hot-spraying polished rod competitiveness of product in market, have influenced the popularization of this outstanding process for treating surface of plasma spray technology in the oil equipment field.
