Description
Technical field
The present invention relates to the manufacturing technology field of oil field equipment, especially relate to a kind of oil well pump.
Background technique
Oil well pump is to utilize the pressure difference before and after the ball valve that crude oil is promoted to the key equipment on ground, and its quality directly has influence on the output and the cost of production in oil field, and the damage that it is vulnerable in use in the oil field most is burn into wearing and tearing and sand card etc.China oil field has entered tertiary recovery, water filling, carbon dioxide injection, polymer injection etc. are a series of to increase oily measure, makes the environment of down-hole abominable day by day, and the sand content of well liquid, corrosive deposit are also more and more, the working life of oil well pump is also shorter and shorter, and the cost for oil production in oil field increases year by year.In order to prolong the working life of oil well pump, present solution is to lay the sintering class ceramic sleeve of segmentation at oil well pump pump barrel inwall and plunger outer wall, though this improvement is outstanding in performance such as wear-resisting, high temperature resistant, corrosion-resistant, but fragmentation takes place in ceramic sleeve easily, burst apart and phenomenon such as dislocation, and impact resistance is low, thereby has influence on the usability of oil well pump, is unfavorable for long-time oil producing operation, while sintering class pottery cost height, and yield rate is lower.
Summary of the invention
Technical problem to be solved by this invention provides a kind of anticorrosion, wear-resisting, high temperature resistant, antiscale, wax control and sand control card and shock resistance height, cost is low, discharge capacity is big advanced ceramic pipe type defueling pump.
For solving the problems of the technologies described above, the invention provides a kind of advanced ceramic pipe type defueling pump, comprise pump barrel, plunger, upper travelling valve assembly, lower travelling valve assembly, standing valve assembly, it is characterized in that: foil high temperature resistant, wear-resisting, the corrosion resistant advanced ceramics protective layer of one deck on the base steel inner tube wall of pump barrel; The stopper rod body outer surface is preset with groove at interval and is coated with the wear-resistant corrosion resistant alloy coat of one deck, and the Zirconia reinforced alumina ceramic ring is inlayed on the alloy coat surface in the groove.
For guarantee oil well pump in high corrosive environment stable operation and reduce fuel-displaced resistance, the standing valve cover oil outlet adopts streamlined three-flute structure.
For increasing the flow channel for liquids area, quicken valve ball and fall speed after rise, the valve bonnet that moves about adopts open three-flute structure.
For increasing oil well pump working life, valve ball, valve seat adopt the Y-TZP zirconia ceramics.
For the ease of inlaying and structure stability, ceramic ring is to be combined by three identical circular arc ceramics of specification.
The stopper rod body outer surface is made up of the ni base alloy coating material, and the thickness of alloy coat is not less than 0.254mm.
Advantage of the present invention: the present invention foils aluminium oxide advanced ceramics layer and integral with it on the steel class parent tube inwall of pump barrel, on the alloy coat of plunger surface, inlay several Zirconia reinforced alumina ceramic rings, the direct wearing and tearing of alloy coat and pump barrel have been avoided, make plunger can keep constant best clearance for a long time, can make liquid outlet quantity keep long-term stablizing; Solve also simultaneously that to lay on the class ceramic plunger sintered ceramic ring frangible, the problem that impact resistance is low, cost is high.Through overtesting, advanced ceramics layer hardness more than HV1300, tensile strength 〉=140MPa, crushing strength 〉=22.9KN, shear strength 〉=25MPa.High intensity can guarantee can not influence the oil pumping pump performance in transportation or work progress.Neutral advanced ceramics layer and wax, dirt do not have affinity, fouling, wax deposition phenomenon can not take place, at H
