Description
Technical field
The present invention relates to technical field of engineering machinery, particularly relate to a kind of efficiently online air bubble eliminating device of twin-stage fluid.
Background technology
Fluid is producing, is storing, transporting and is extensively applying in system operation, is therefore mixed into air in fluid and is
Inevitably.Air is to be suspended in oil with the spherical bubble that diameter is the least, and it causes system work bad, such as oil temperature liter
High, cause cavitation, the vibrations causing system and noise, indirectly accelerate the pollution of fluid simultaneously, thus affect system
Stability and the performance of systematic function.
Typically utilize fuel tank to carry out the removal of bubble in hydraulic system, use this fuel tank natural removal method to be exactly
The buoyancy method that emersion pasta dissolves in air voluntarily by bubble self.If the fluid of bubble interface does not move upward
Words, natural buoyancy to be leaned on overcomes the frictional resistance of fluid to move upward.According to Stokes rule, the floating speed of bubble
Spend relevant with the size of bubble and oil viscosity, say, that ascent rate is directly proportional with Air Bubble Size and becomes anti-with oil viscosity
Ratio.Due to the stirring action of pump, the bubble after miniaturization becomes the aqueous bubble of emulsifying, even if at fuel tank through valve port ejection at a high speed again
Interior delay considerable time, is also relatively difficult by floating voluntarily.
Although taking such as horizontal sectional area in the structure of fuel tank to be more than the fluid degree of depth, arrange dividing plate and extend oily existing
The time of staying in fuel tank, oil inlet and outlet arrange far a little as far as possible and volume wants big etc..But still have not from bubble removal effect
Foot, in particular for the fluid that viscosity is bigger, the most efficiently goes degreasing fluid bubble to become urgent need and solves the technical problem that.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that described herein
Specific embodiment only in order to explain the present invention, be not intended to limit the present invention.
As Figure 1-4, the efficient online air bubble eliminating device of twin-stage fluid of the present invention includes gas-oil separating cylinder 1, directing vane
Wheel 2, escape pipe 3, upper cover 4 that described gas-oil separating cylinder upper shed is closed, and be arranged on described escape pipe and manage also
The self-bleeding air bleeding valve 5 of energy, described gas-oil separating cylinder includes the cylindrical shape rotating drum 12 on top and is integrally formed coaxially
Taper disengagement chamber 11 bottom rotating drum, described rotating drum side is tangentially provided with oil inlet pipe 13, and described oil gas divides
Being formed with oil-out 14 bottom cylinder 1, described guide vane wheel 2 can be rotatably set in described rotating drum 12, described
Escape pipe vertical center arranges and fixes with described upper cover and is connected and connected with outside air bleeding valve 5 by disengagement chamber.
Meanwhile, for tapered spiral is spiraled and under fluid guide, on the inwall of described gas-oil separating cylinder
Being provided with cone-type spiral and guide rib 13, the coil direction of described spirally-guided rib is identical with fluid precession direction, spirally-guided
The rib guiding to fluid so that it is keep screw, it is to avoid dramatic decrease, it is ensured that oil gas separation, further, for improving
Separating effect to little microbubble, is provided with filter house 6 in the bottom of described gas-oil separating cylinder, and described filter house is formed
Having filter opening, filter opening diameter, at 0.2-1mm, uses filter opening to filter, can retain micro-bubble and be pooled air pocket, so
Rear floating is discharged, and described filter house is positioned at gas-oil separating cylinder lower height 1/4-1/3.
The present invention uses whiz formula structure to design, and when fluid enters cavity from tangential direction, rushes at certain kinetic energy
Guide vane wheel, under the guiding function of guide vane wheel, because space is less relative to oil inlet pipe at guide vane wheel, fluid is made to accelerate fortune
Dynamic and that coiled coil is to bottom oil-out is advanced, owing to fluid density is more than bubble density, under the influence of centrifugal force, fluid
Extruding bubble gather at central axis near disengagement chamber inwall, the pressure on central axis is as fluid spiral acceleration
Increase and successively decrease, minimum at disengagement chamber middle and lower part center pressure, bubble pressure reduction on central axis and close to central liquid
Moving 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
