Description
Technical field
The present invention relates to a kind of novel alloy coating hot spray oil pumping polish rod production line, 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, less investment, and convenient management, advantage such as adaptability 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 sucker rod string top one Gent, be used for and well head seal box fitted seal mouth of pumped oil well, therefore working conditions is more abominable than sucker rod, except that the working conditions 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 atomospheric 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 working conditions.
For this reason, oil pumping polish rod being carried out surface treatment is to prolong its work-ing life the most effectively to handle means to improve its erosion resistance and wear 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 protective layer on the oil pumping polish rod surface by plating; this surface hardness height, highly polished, certain wear resistance and erosion resistance arranged; slowed down the erosion resistance of oil pumping polish rod to a certain extent; but because electrolytic coating and matrix bond are not tight; tangible interface is arranged between electrolytic coating and the matrix; it is very big that the composition of both sides, interface matrix and electrolytic 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 hot-spraying techniques to be covered in the oil pumping polish rod surface, and make coated material and body 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 body material, there is certain thickness zone of transition, 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 chromium coating and nickel-phosphorus coating after defective appears in the surface, to cause the coating sheet to come off because of the corrosive expansion.
But, because alloy coating hot-spraying technology work flow relative complex, and oil pumping polish rod is typical ultra-fine stock class part, 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 mode of production is that sucker rod hard surfacing equipment is carried out scrap build comparatively widely at present, utilize quenching apparatus to finish the preheating to the body of rod, the remelting processing of body of rod top coat, utilize the abrasive band bistrique on the sucker rod hard surfacing equipment that the is placed on side that increases in addition and the thermal spraying treatment that the flame heat spray spray gun is finished body of rod surface coarsening, coating polishing grinding and body of rod surface alloy coating.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, after rotating, roller utilize frictional force to drive workpiece axially rotation on the one hand, move axially promptly spiral advancing simultaneously on the one hand.Stability of motion is very poor owing to the size characteristics of its ultra-fine length for sucker rod in this process, and beating degree is very high, has had a strong impact on the polishing on body of rod surface, the processing quality of top coat thermal spraying treatment.Therefore also need workpiece support and move mode are transformed, the spiral progression of workpiece is decomposed into independently rotation and moves axially two mode of motion, utilize the fixed position roller to support support and the rotation that realizes workpiece, guide rail cart drive workpiece moves on guide rail and realizes moving axially of workpiece.
Can realize the thermal spray process of either of the top 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 intermediate frequency remelting effect and efficient, 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 is to operator's operational requirement height, 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 extensive popularization of this outstanding process for treating surface of hot-spraying techniques in the oil equipment field.
