Abstract
The invention discloses an oil leakage preventing device used for a turbosupercharger. The oil leakage preventing device comprises a machine core rotor, an impeller and an intermediate shell, wherein a shaft seal fixing sleeve is arranged between the machine core rotor and the intermediate shell, the impeller is arranged on the machine core rotor outside the shaft seal fixing sleeve, an oil leakage preventing fan is arranged between the shaft seal fixing sleeve and the impeller on the machine core rotor, and the machine core rotor drives the oil leakage preventing fan to blow air to the inside of a machine core while rotating. According to the oil leakage preventing device used for a turbosupercharger, the oil leakage preventing fan is additionally arranged on the machine core rotor between the shaft seal fixing sleeve and the impeller, and the structure is simple. The fan blade structure is designed, so that the machine core rotor produces proper air pressure during rotation to blow air to the direction of the machine core, and therefore, the function of oil leakage prevention at the pressure end can be effectively achieved, the thrust effect to a thrust bearing is not affected, and the influence to the complete machine is slight.
Description
Technical field
The present invention relates to a kind of turbocharger, especially relate to a kind of oil-leakage-prevention for turbocharger and fill
Put.
Background technology
A kind of air compressor of turbocharger, increases air inflow by compressed air.It is
Utilizing waste gas inertia impulsive force that electromotor discharges to promote the turbine in turbine room, turbine drives again coaxial leaf
Wheel, the air that impeller force feed is sent here by air filter pipeline, it is allowed to supercharging and enters cylinder.When electromotor turns
Speed increases, and the waste gas velocity of discharge is the most synchronize with secondary speed to be increased, and impeller just compresses more air and enters gas
Cylinder, the pressure of air and density increase the more fuel that can burn, and corresponding increase fuel quantity and adjustment are started
The rotating speed of machine, it is possible to increase the output of electromotor.
At present, an axle envelope is only set between movement rotor and the middle casing of existing turbocharger and determines interplanting
For sealing, in concrete application process, at this, easily there is leakage of oil, affect the normal work of turbocharger
And overall performance.
Summary of the invention
It is an object of the invention to provide a kind of anti-oil leakage device for turbocharger, it has structure letter
The feature that list, oil-leakage-prevention are effective and little on overall performance impact, to solve turbocharger in prior art
The problems referred to above existed.
For reaching this purpose, the present invention by the following technical solutions:
A kind of anti-oil leakage device for turbocharger, it includes movement rotor, impeller and middle casing,
Arranging the fixed set of axle envelope between described movement rotor and described middle casing, it is fixed that described impeller is installed on described axle envelope
On movement rotor outside set, wherein, described movement rotor is provided with between the fixed set of described axle envelope and impeller
Oil-leakage-prevention fan, drives oil-leakage-prevention fan to dry to movement internal direction when described movement rotor rotates.
Especially, described oil-leakage-prevention fan is made by casting or any one mode mach.
Especially, described oil-leakage-prevention fan includes that body, the center of described body offer cooperation movement and turn
The installing hole that sub-external diameter is arranged, and in the outer rim of described body, it is evenly equipped with several flabellums.
Especially, a diameter of 15mm～25mm of described oil-leakage-prevention fan.
Especially, described flabellum is obliquely installed on described body, and the angle of inclination of described flabellum be 10 °～
20°。
Especially, the quantity that arranges of described flabellum is 8～15.
Beneficial effects of the present invention is, compared with prior art the described anti-oil leakage device for turbocharger
Set up oil-leakage-prevention fan on movement rotor between the fixed set of axle envelope and impeller, only increase a finding, dress
Join relation simple.According to the design to flabellum, make movement rotor produce in rotation process suitable blast to
Dry in movement direction, so can the effect of very effective generation pressure side oil-leakage-prevention, and do not affect thrust
The thrust effect of bearing is the least to the performance impact of complete machine.
