Description
Technical field
The utility model is related to a kind of oil-well pump for extracting oil, more particularly, to it is a kind of can enforced opening draining oil pumping
Pump.
Background technology
With the rapid development in oil field, safety and environmental protection problem is increasingly taken seriously.Particularly oil well repairing operation when
Sump oil emission problem, it is the arch-criminal of environmental pollution.Oil pump is to be driven crude oil in well to give rise to the normal of ground by oil pumper
Use downhole hardware.Common oil well pump is mainly made up of pump barrel, inlet valve, piston, the major part of drain four.According to oil well pump in well
Under fixed form, tubing pump and insert pump can be divided into.Tubing pump is also known as oil-line pump, and feature is outer barrel, bushing and inlet valve
Assemble and be attempted by rod-type pumping unit on ground, in oil pipe bottom elder generation lower going-into-well, then the piston equipped with dump valve with taking out
Beam hanger passes through in oil pipe tripping in pump.Bushing is processed into some sections by material, is lining into outer barrel.Piston is made of seamless steel pipe
Hollow circular cylinder, smooth outer surface carries annular ditch groove, and effect is to allow the sand grains into piston and sleeve clearances to be gathered in ditch
In groove, sand grains worn piston and bushing are prevented, and the oil deposited in groove plays a part of to lubricate piston face.
Inspection is to release the oil in oil pipe when pumping up pump, can use salvageable inlet valve（Standing valve）, by transferring roofbolt,
Allow the buckle of piston to bite the fishing head of inlet valve, inlet valve is proposed.But this pump is accounted for due to inlet valve fishing head
According to space in pump, make the dead space of pump and clearance volume big, easily influenceed by gas and reduce pump efficiency.Current most of tripping in
The well of tubing pump, it is that bleeder is installed in oil pipe bottom, oil in oil pipe is laid down by opening bleeder.In the well of the big pump of tripping in
In, because piston diameter is more than pipe aperture, it is impossible to which, by oil pipe tripping in piston, the method for use is first with oil pipe piston
Enter in well, rear tripping in rod string, the device that disjointed device is referred to as using one is docked with piston in pump.Tubing pump is simple in construction,
Cost is low, allows the pump footpath of tripping in big compared with insert pump under identical tubing diameter, thus discharge capacity is big.But oil must be removed when examining pump
Pipe, well-repairing work amount is big, therefore little suitable for lower-continuous mapping, the higher well of yield.When tubular type pumps up pump, bleeder is by oil pipe
In Residual oil leak into sleeve pipe, be easy to workover treatment.
At present, to remember letting out the fluid in tubing string during well operations and fall in well, Normal practice is the pump in oil well pump
Cylinder is lower to connect a shear pin type bleeder between box cupling and standing valve cover, draining is realized by pounding disconnected draining bolt.This kind of draining
Method mainly has the disadvantage that：When draining bolt be not easy to pound it is disconnected；Second, oil leak hole is too small, draining speed is too slow.Cause tubing string
Interior fluid can not be let out and fall in oil well, cause draining to fail.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides one kind and opens draining oil well pump, this practicality by force
It is new to adopt the following technical scheme that：It is a kind of strong to open draining oil well pump, including fixed valve assembly, pump barrel assembly, strong to open draining total
Into, assembly for plunger and rod assembly, the fixed valve assembly is by fixed valve base joint, fixed valve base, fixed valve ball and standing valve
Cover is formed, and the pump barrel assembly is by box cupling is formed on box cupling, pump barrel and pump barrel under pump barrel.The pump barrel inner surface, using carbon nitrogen
Boron co-diffusion（Patent of invention number：ZL201310166047.0）Surface Hardening Treatment is carried out, there is anti-corrosion, wear-resisting.It is described
Assembly for plunger is that spiral is strike-off plunger（The patent No.：ZL200720159097.6）, outer plunger surface is using Co-based alloy powder spray
Weldering, strengthens its anti-corrosion, anti-wear performance.It is described it is strong open draining assembly by tubing nipple, draining box cupling, valve opening pressing plate, sealing shroud and
Core retainer plate form, be circumferentially with multiple oil leak holes in the draining box cupling, periphery of these oil leak holes along draining box cupling into
Circular arrangement is simultaneously deep at the sealing shroud of the central interior of draining box cupling, and the tubing nipple upper end connects draining box cupling, under
Box cupling on end connection pump barrel, valve opening pressing plate is touched less than draining box cupling when the length of tubing nipple can ensure to carry dead space, described
Valve opening pressing plate is arranged on assembly for plunger upper end, and the rod assembly is made up of hoop on pull bar and pull bar, outside the pull bar
Core retainer plate is cased with, sealing shroud is cased with outside the core retainer plate, valve opening pressing plate and assembly for plunger, upper termination pull bar are terminated under the pull bar
Upper hoop.
Preferably, the endoporus of the draining box cupling is taper, first more convenient installation when assembling, secondly favourable
In the friction for reducing entrance, interference fit can transmit larger torque（Be hit load when need the cooperation of plus key）, producing
It is widely used in practice, is mainly used in the connection of axle and hub, the connection of wheel rim and core wheel and rolling bearing and axle or bore
Connection etc..Plunging and temperature differential method are used in assembling process.Plunging is will to be enclosed part using forcing press to be pressed directly into enclosing element
In, due to the presence of the magnitude of interference, in process of press in, the peak point of matching surface nao-and micro relief is inevitably abraded
Or flatten, thus reduce the tightness of connection.Temperature differential method is that part is enclosed in heating enclosing element or cooling, is allowed to both be easy to assemble,
Damage matching surface can be reduced or avoided again, and can reach very firm connection at normal temperatures.
It is further preferred that the sealing shroud outer surface is shaped as back taper, the internal via shape phase with draining box cupling
Match somebody with somebody, it is easy for installation, and can closely connect；Using nylon material, engineering plastics of the nylon as big dosage, machine is widely used in
The fields such as tool, automobile, electrical equipment, textile equipment, chemical industry equipment, aviation, metallurgy.As indispensable structural wood in every profession and trade
Material, its main feature are as follows：1. excellent mechanical property.The high mechanical strength of nylon, good toughness.2. self-lubricity, rub resistance
It is good.Nylon has drinks self-lubricity very well, and coefficient of friction is small, so as to as transmission parts its service life length.3. excellent is heat-resisting
Property.The heat distortion temperature of such as nylon 46 high crystalline nylon is very high, long-term phase use, PA66 can pass through glass at 150 DEG C
After fiber reinforcement, its heat distortion temperature reaches more than 250 DEG C.4. excellent electrical insulation capability.The volume resistance of nylon is very high,
Breakdown voltage resistant height, it is excellent electric, electrical apparatus insulation material.5. excellent against weather.6. water imbibition.Nylon water imbibition
Greatly, saturation water can reach more than 3%.The dimensional stability of product is being influenceed to a certain degree.
Compared with prior art, the beneficial effects of the utility model are：1st, there is enforced opening oil draining function, draining success
Rate is high；2nd, leakage passage is big, and draining speed is fast, it is ensured that quick draining；3rd, may be reused.
