Description
Technical field
The present invention relates to oil and gas multiphase flow technical fields, and in particular to a kind of spiral that splitterr vanes are reversely thickeied with postposition
Axial-flow pump impeller.
Background technique
The demand of the development of world economy, countries on petroleum and natural gas is growing day by day.With advances in technology, petroleum and
Gas extraction technique is constantly reformed.Oil-gas gathering and transportation is an important component in oil and gas exploitation technique, tool
Body just refers to oil well crude oil produced, natural gas and remaining product accumulation, defeated to oil plant by handling and processing
It mainly include Oil-gas Separation and metering, crude oil dehydration, natural gas purification, lighter hydrocarbons recovery with the technique overall process of natural gas user
Etc. techniques.From technique, the collection respectively that oil-gas gathering and transportation can be divided into petroleum gas is defeated and mixing collects defeated two major classes.Recent decades
Come, as the construction of offshore oil and gas field increases increasingly, oil and gas multiphase flow does not need to increase separator, can cut down the pipe of laying yet
Road amount is suitble to the long-distance sand transport with blends of crudes, and can save substantial contribution, therefore, oil-gas mixed delivery pump in exploitation
Research is increasingly becoming heat subject.Currently, China is also in the world with the technology relative maturity in the U.S., Britain, Germany, Japan
It is still in conceptual phase, it is temporarily external without products export.
Mainly there are three measurement indexs for the performance of oil-gas mixed delivery pump: pressure, the oil-gas ratio scope of application, efficiency.If three
Index is all high, and performance is better.For current research, screw pump is suitable for big oil-gas ratio than single-screw (single screw) pump, can reach
Gassiness 90%.The a few countries such as U.S. can handle 100% liquid to 100% gas.But the characteristic of pump is theoretically also less clear
Chu, when air content increases, long-term operation causes the problem of pumping fever to solve there are no fine；Using new structural liquid
(10~15) × 105Pa, but low efficiency can be improved in ring pump pressure；General centrifugal pump is mixed into some air cannot normal work
Make.Now by structure of modification, being mixed into 20% gas can still work, but the requirement of oil and gas multiphase flow is much not achieved in this.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of designs reasonably to have postposition anti-
To the spiral axial-flow impeller of pump for thickening splitterr vanes, thickeied by splitterr vanes to the pressurization of exit two-phase medium and reversely
Feature exerts a force to it, to improve the efficiency of mixing pump.
In order to achieve the above objectives, present invention employs following technical proposals: it includes wheel hub, helico-axial blade；Wheel
Several helico-axial blades are fixed on the outer ring surface of hub in the shape of a spiral, the space between several helico-axial blades is constituted
Runner；Reversed thickening splitterr vanes are equipped in the runner of the close exit position of each helico-axial blade.
Further, each reversed splitterr vanes that thicken are vertically fixed on the outer ring surface of wheel hub.
Further, the reversed thickening splitterr vanes are cambered surface laminated structure, surface and helico-axial blade
Surface between form the runner of gradual change variable diameter, from the thickness from wheel hub connection to rim location in gradually incrementally setting
It sets.
The working principle of the invention: reversed thickening splitterr vanes are installed additional in the exit position of blade, for improving impeller
Exit static pressure, to reduce the separation degree of oil gas；At the same time, increased splitterr vanes are arranged to the purpose reversely thickeied
It is the design feature reversely thickeied using reversed thickening splitterr vanes, when liquid phase is separated by larger centrifugal force with gas phase,
It is reversed thicken splitterr vanes it is applied with centrifugal force opposite effect power, and then be sufficiently mixed gas-liquid two-phase more.
After adopting the above structure, divide the beneficial effects of the present invention are: the present invention provides one kind there is postposition reversely to thicken
The spiral axial-flow impeller of pump for flowing blade, by splitterr vanes to the pressurization of exit two-phase medium and reversed the characteristics of thickening to it
Force, to improve the efficiency of mixing pump.
Detailed description of the invention:
Fig. 1 is structural schematic diagram of the invention.
Description of symbols:
Wheel hub 1, helico-axial blade 2, reversed thickening splitterr vanes 3.
Specific embodiment:
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clearly and completely
Description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
As shown in Figure 1, present embodiment adopts the following technical scheme that it includes wheel hub 1, helico-axial blade 2；
Several helico-axial blades 2, the sky between several helico-axial blades 2 are fixed on the outer ring surface of wheel hub 1 in the shape of a spiral
Between constitute runner；Reversed thickening splitterr vanes 3 are equipped in the runner of the close exit position of each helico-axial blade 2；
Each reversed splitterr vanes 3 that thicken are vertically fixed on the outer ring surface of wheel hub 1, and the reversed splitterr vanes 3 that thicken are cambered surface piece
Shape structure, between surface and the surface of helico-axial blade 2 formed gradual change variable diameter runner, from 1 connection of wheel hub
Thickness to rim location, when liquid phase is separated by larger centrifugal force with gas phase, reversely adds in being gradually incrementally arranged
Thick splitterr vanes 3 it is applied with centrifugal force opposite effect power, and then be sufficiently mixed gas-liquid two-phase more.
The working principle of this specific embodiment:: conventional helical axial-flow pump is when conveying the blending agent of oil gas, due to oil
The density variation of gas two-phase causes impeller suffered centrifugal force when doing work to the two different, so gas phase media is in impeller blade
The aggregation of 2/3rds wheel hubs is exported, and after having installed reversed thickening splitterr vanes 3 additional, impeller outlet static pressure can be improved, thus
The separation degree for reducing oil gas, improves the efficiency of mixing pump；The purpose for being arranged to reversely thicken is to shunt leaf using reversed thicken
The design feature of piece 3, when liquid phase is separated by larger centrifugal force with gas phase, it is reversed thicken splitterr vanes 3 it is applied with
Centrifugal force opposite effect power, and then it is sufficiently mixed gas-liquid two-phase more.
After adopting the above structure, the beneficial effect of present embodiment is: present embodiment provides a kind of tool
There is postposition reversely to thicken the spiral axial-flow impeller of pump of splitterr vanes, by splitterr vanes to the pressurization of exit two-phase medium and instead
To exerting a force the characteristics of thickening to it, to improve the efficiency of mixing pump.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of invention.
