The online air bubble eliminating device of fluid
Technical field
The present invention relates to technical field of engineering machinery, the online air bubble eliminating device of more particularly to a kind of fluid.
Background technology
Fluid is extensively applied in production, storage, transport and system operation, therefore air is mixed in fluid is
Inevitably.Air is suspended in oil with the spherical bubble of diameter very little, and which causes system work bad, such as oil temperature liter
It is high, cause cavitation, the vibrations for causing system and noise, while indirectly accelerate the pollution of fluid, so as to affect system
The performance of stability and systematic function.
The removal of bubble is typically carried out in hydraulic system using fuel tank, using this fuel tank natural removal method is exactly
By the buoyancy method that voluntarily emersion pasta dissolves in air of bubble itself.What if the fluid of bubble interface was not moved upwards
Words, to be leaned on natural buoyancy to overcome the frictional resistance of fluid and move upwards completely.According to Stokes rule, the floating speed of bubble
Degree is relevant with the size of bubble and oil viscosity, that is to say, that ascent rate is directly proportional to Air Bubble Size, and oil viscosity into anti-
Than.Due to the stirring action of pump, the ejection of Jing valve ports high speed becomes emulsion shape bubble to the bubble after miniaturization again, even if in fuel tank
Interior delay considerable time, is also relatively difficult by voluntarily floating.
Although taking such as horizontal sectional area to be more than fluid depth, arrange dividing plate and extend oil and exist in the structure of fuel tank
The time of staying, oil inlet and outlet in fuel tank as far as possible arrange far a little and volume will be big etc..But still have not from bubble removal effect
How foot, in particular for the fluid that viscosity is larger, efficiently go degreasing fluid bubble to become the technical problem for being badly in need of solving.
The content of the invention
The purpose of the present invention is, for technological deficiency present in prior art, and to provide a kind of fluid online bubble removing dress
Put.
To realize that the technical scheme adopted by the purpose of the present invention is:
A kind of online air bubble eliminating device of fluid, including gas-oil separating cylinder, guide vane wheel, escape pipe, by described oil gas point

Described escape pipe lower end is formed with interior chamfering.
Compared with prior art, the invention has the beneficial effects as follows:
The online air bubble eliminating device of the present invention, is capable of achieving pure mechanic structure, without the need for power, runs with fluid and runs,
Bubble can effectively be accelerated to gather.And this equipment is easy for installation, it is not necessary to extra matching design, plug and play is capable of achieving.If
It is standby small volume, lightweight, and the employing of guide vane wheel, rotated using its rotation forces fluid, overcome the larger fluid of viscosity
The drawbacks of cannot rotating at a high speed, improves final oil gas separation.
Description of the drawings

Fig. 2 show internal structure schematic diagram;
Fig. 3 show cross section structure schematic diagram.
Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment only to explain the present invention, be not intended to limit the present invention.
As Figure 1-3, the online air bubble eliminating device of fluid of the invention includes gas-oil separating cylinder 1, guide vane wheel 2, outlet
On pipe 3, the upper lid 4 that described gas-oil separating cylinder upper shed is closed, and the escape pipe described in being arranged on, Guan Bingneng is arranged automatically
The air bleeding valve 5 of gas, described gas-oil separating cylinder include the cylindrical shape rotating drum 12 on top and are coaxially integrally formed in rotating drum
The taper disengagement chamber 11 of bottom, described rotating drum side are tangentially provided with oil inlet pipe 13, described 1 bottom of gas-oil separating cylinder
Oil-out 14 is formed with, described guide vane wheel 2 is can be rotatably set in described rotating drum 12, and described escape pipe is vertical
It is centrally located and is fixedly connected with described upper lid and disengagement chamber is connected with the air bleeding valve 5 of outside.
The present invention adopts whiz formula structure design, when fluid enters cavity from tangential direction, is rushed at certain kinetic energy
Guide vane wheel, under the guiding function of guide vane wheel, because space is less with respect to oil inlet pipe at guide vane wheel, fluid is made to accelerate fortune
Dynamic and coiled coil is advanced to the oil-out of bottom, as fluid density is more than bubble density, under the influence of centrifugal force, fluid
Extrude bubble and gather at central axis near separation cavity wall, the pressure on central axis is with fluid spiral acceleration
Increase and successively decrease, in disengagement chamber middle and lower part, center pressure is minimum, pressure reduction of the bubble on central axis and is close to central liquid
Move at the minimum diameter of disengagement chamber under the related effect of stream and gather, the gas being accumulated in a large number is under the effect of the pressure
Into exhaustor, outside final bubble Jing air bleeding valve dischargers.Meanwhile, it is to improve collecting effect of the collecting pipe to bubble, institute
3 lower end of escape pipe stated is formed with interior chamfering 31, or arranges horn mouth in described escape pipe lower end.
The online air bubble eliminating device of the present invention, is capable of achieving pure mechanic structure, without the need for power, runs with fluid and runs,
Bubble can effectively be accelerated to gather.And this equipment is easy for installation, it is not necessary to extra matching design, plug and play is capable of achieving.If
It is standby small volume, lightweight, and the employing of guide vane wheel, rotated using its rotation forces fluid, overcome the larger fluid of viscosity
The drawbacks of cannot rotating at a high speed, improves final oil gas separation.
Wherein, described guide vane wheel 2 includes center connection ring 21, is arranged in the multiple of described center connection ring ring week
Blade 22, described center connection ring is rotatable with described escape pipe to be fixedly connected, and is to improve the promotion effect to fluid, excellent
The described blade profile of choosing is steepest curve, i.e., described cambered design of the blade in steepest curve, is reducing entry resistance
In the case of, more fluid can be promoted to be rotated.
Specifically, be the guide vane wheel for realizing described rotatable fixation, be fixedly installed on described escape pipe 3
Bearing 32, is formed with positioning convex ring corresponding with described bearing and by positioning snap ring by institute in the middle part of described center connection ring
The bearing stated is positioned therebetween, meanwhile, described escape pipe is welded and fixed with upper lid and is connected, will escape pipe, guide vane wheel and on
Lid is connected to one, and is connected using monoblock type, installation effect is effectively ensured, while keeping in repair beneficial to later stage internal cleaning.Its
In, it is the bonding strength for improving escape pipe and upper lid, being fixedly installed on described upper lid will be described escape pipe embedding containing which
In sleeve pipe 41, described sleeve pipe 41 and described escape pipe interference fit or be welded to connect to increase the intensity of escape pipe, protect
Card guide vane wheel even running.
It is to improve to the guiding effect into fluid, promotes which to rotate, described guide vane wheel is with upper lid gap in 0.8-
1.5mm, such as 1mm, the outer ledge of described guide vane wheel with described rotation cavity wall gap in 0.8-1.5mm, such as 1mm,
After i.e. fluid enters rotating drum, certainly will be to be driven to rotate by blade at a high speed, power be provided for follow-up rotating separation.
The above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, some improvements and modifications, these improvements and modifications can also be made
Also should be regarded as protection scope of the present invention.
