Background technique

The hydraulic system that numerical control machine tool is conventional is open hydraulic system, and it is inevitable for containing air in hydraulic oil.Air in hydraulic oil is called dilution air, and dilution air is suspended in oil with the spherical bubble that diameter is very little, is mainly blended in oil by the suction pipe of fuel tank and pump.Such as: tank-level is too low, pump suction pipe mouth is partly exposed to pasta or flood dark very shallow time, the in-line gas leakage of pump, the system oil return mouth of pipe higher than the system oil return etc. of tank-level, high velocity jet, air all may be made to enter in oil.While oil is brought into system by oil pump, air also just enters hydraulic system.Because in fluid, the content of air increases with the increase of pressure, the fluid being in saturation state when the air dissolving some flows through restriction or pump intake section, when absolute pressure drops to the air separation pressure of fluid, in fluid, oversaturated air will be precipitated, making the micro air bubble be originally dissolved in oil be gathered into larger bubble appears in hydraulic system, conventional bubble removal method is always made an effort on fuel tank, namely fuel tank indispensable in hydraulic system is utilized to carry out the removal of bubble, such as allow its horizontal sectional area be greater than the fluid degree of depth when tank design, the time that dividing plate prolongation fluid stops in fuel tank is set, oil inlet and outlet arranges far a little as far as possible and volume wants large etc.Be exactly lean on the buoyancy of bubble self float to liquid level voluntarily and be held into air principle.The very little about 0.25 ~ 0.5mm of diameter due to bubble, and fluid has surface friction drag to bubble.Being directly proportional to Air Bubble Size according to the known gas bubble light soil of the method for Stokes, being inversely proportional to oil viscosity, is 10 if diameter is the bubble of 0.3mm in viscosity ^-4per minute floating 30mm in the fluid of m2/s, so by very poor from floating removal effect, for this reason, we propose a kind of efficient bubble remover.

Summary of the invention

The object of the present invention is to provide a kind of efficient bubble remover, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the invention provides following technological scheme: a kind of efficient bubble remover, comprise housing, oil exit pipe, guide vane wheel, oil suction chamber, oil inlet pipe, active chamber, oil extraction head, mounting groove and bearing, one of described oil exit pipe is inserted in housing, left side head exposes housing, leaves gap between right side head and oil extraction head; Described bearing is arranged on oil exit pipe, and described guide vane wheel is arranged on bearing, and described oil inlet pipe is positioned at housing upper, and is connected with oil suction chamber, and described oil extraction head is positioned at the cavity of the active chamber rightmost side.

Preferably, described oil exit pipe and oil inlet pipe are equipped with adapter mounting groove.

Preferably, described active chamber is a conical structure.

Working principle: when fluid enters oil suction chamber from the tangent direction of guide vane wheel, guide vane wheel sheet is rushed at certain kinetic energy, under the effect of guide vane wheel, fluid makes propeller accelecrated motion, because fluid density is greater than bubble density, under the influence of centrifugal force, bubble is assembled to central axis place, pressure on central axis successively decreases along with the increase of liquid spiral acceleration, minimum at the center pressure at active chamber minimum diameter place, the pressure reduction of bubble on central axis and assembling to the motion of active chamber minimum diameter place close under the related effect of central liquid stream, near the right side of active chamber and oil extraction head junction, liquid stream is not owing to having spiral motion, so pressure is herein higher than the pressure of oil exit pipe ingress, the gas be accumulated in a large number is under the effect of the pressure by outside oil exit pipe discharger.
