Description
Art
The present invention relates to new polymers injection pump diversion component, is applied especially to the improvement of polymer injection pump and uses it
In.
Background technology
Polymer is substantially the aqueous solution of polypropylene phthalein amine (PAM), and the solution is a kind of very big compound of molecular weight, tool
There are high viscosity and elastomeric feature.With conventional pumps come polymer injection, will show to this high viscosity, long chain material
Inadaptability, shows as that volumetric efficiency is low, and suction capacity is poor, and viscosity degradation rate is high, and performance is unstable, the shortcomings of poor reliability.
Daqing oil field is the oil field that domestic application polymer displacement of reservoir oil tech is earliest and technology is most ripe.The polymer injection pump configuration used
Mostly same or like, onsite application produced problem has the following aspects:Injection rate is inadequate, the viscous damage of polymer is excessive, makes an uproar
Sound is big and the problems such as seal leakage;Also have in addition the crankshaft wear of injection pump power end, tile kilning phenomenon, crosshead abrasion and
The problems such as electromotor high-temperature.Polymer injection pump belongs to high-pressure pump, high pressure effect under, fluid end in design there is enter,
Discharge opeing valve base and pump housing hydraulic chamber sealing structure are unreliable, internal leakage is serious;Water under high pressure washes away pump housing working chamber and valve
Seat is serious, the pump housing and combination valve life-span are low;Liquid feed valve and tapping valve take sliding valve structure, higher to water quality requirement, work as use
Poorly sealed close during turbid circulating water, sealing surface washes away seriously, quick abrasion, and the life-span is low;With gland hydraulic pressure " card often occurs for valve plate
Fracture defect often occurs for extremely " failure, valve rod;Efficiency is low, maintenance cost is high, equipment energy consumption is high, operating rate is low, operating pressure can not
Ensure.Counted according to fault time, fluid end failure accounts for high pressure failure of pump 90% or so.After water injecting pump uses a period of time, pump
Pressure, discharge capacity reduce, and have abnormal vibrations.
These problems generation it is relevant with the workmanship, onsite application, later maintenance of complete machine first, also with scene note
Enter condition continuous change and injected media continuous conversion it is relevant.The flow passage components of this paper primary study polymer injection pumps
Structure Improvement Design and material selection, the smooth implementation of the problem and effectively utilize, solve grand celebration and recover the oil the polymerization of 8, four factory
The problem of pump efficiency of 138 injection pumps of thing injection station is low, and noise is big, the viscous damage of polymer is high and maintenance cost is high, has one
Fixed promotional value.
The content of the invention
In order to overcome existing polymer injection pump diversion component sealing property poor, and drag losses is larger during work
Problem, the present invention provide new polymers injection pump diversion component, and the type new polymers injection pump diversion component has good
Sealing property, improve resistance loss ability；It is simple in construction on the basis of ability to work is ensured, convenient disassembly,
Good manufacturability, there is good interchangeability as far as possible.
The technical solution adopted for the present invention to solve the technical problems is：Excessively stream assembly material selection be mainly leading truck,
Cost and processing are considered in the material selection of valve seat, four kinds of valve element, spring parts, wherein leading truck, valve seat, valve core material selection
Manufacturability, 2Cr13 stainless steels being selected, carry out Tempering and Quenching, processing technology ensures the surface roughness Ra more than 1.6 of part,
It is smooth to be so advantageous to polymer flow passage, reduces viscosity loss.
The structure choice oval groove of leading truck, although processing characteristics is than circular hole, some are complicated, are reducing polymer flow
Logical aspect of performance is greatly increased, and wedge angle is handled inside elliptical aperture in addition, and face seal surface roughness enters one
Step improves, and ensures sealing property requirement.Valve seat on the basis of strict processing technology, ensures the wearability of matching surface with valve element
And rotproofness, surface hardening processing is carried out, finally carries out pairing grinding, ensures sealed reliable, ensures pump overall volume efficiency.It is excellent
The material of spring has been selected, from Meng Naier, on the premise of the rigidity and intensity of spring can meet requirement, has preferably been improved
Reliability.
The beneficial effects of the invention are as follows：The new polymers injection pump diversion component has sealed reliable, reduces or avoids
The effect of leakage loss after closing；It is more preferable that two kinds of filler central spacers are installed and used effect, polytetrafluoroethylene (PTFE) is every splitting a filler expansion
Property and lubricity are good, beneficial to sealing, are used in combination with both soft graphites, sealing, life and reliability greatly improve.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is excessively stream general assembly schematic diagram after improving.
In Fig. 1,1. leading trucks, 2. valve elements, 3. springs, 4. valve seats.
Embodiment
Preferably, injection pump packing cartridge includes packing box, plunger, filler, guide sleeve, gland and filler pressure cap.
Preferably, packing box length reduces, appearance and size reduces, fixed bolt hole is more reasonable, is advantageous to install, dismantles
And maintenance, the crudy and surface roughness of part are improved, bolt hole arrangement is more reasonable, is actually made with reference to scene
Make, ensure convenient disassembly, according to the requirement of the size of original pump head plunger working chamber and the specific length of filler, rational modification
Packing box inner hole size, ensure the requirement of seal length and sealing property.
Preferably, in order to reduce difficulty of processing, while repair density and maintenance cost are reduced, piston structure is by original
Monoblock type becomes split type, plunger and packing seal face part is manufactured into two parts with plunger extension bar, simultaneously because sealing surface
Length is reduced so that processing is more prone to, and machining accuracy is improved, and the sealing property of plunger and filler is ensure that, before improvement
When changing plunger, filler need that fluid end whole dismounting is got off to be changed and repaired, plunger changes post after becoming split type
Fluid end cylinder body need not be dismantled when plug, filler, significantly reduces repair density and maintenance cost, is solved to site operation personnel
Determine big problem.
