Abstract
The utility model discloses a kind of oil-leakage-prevention turbocharger.Including booster ontology, the booster ontology includes compressor high-pressure chamber and impeller back cavity, is interconnected by opening up a conduction hole between the compressor high-pressure chamber and impeller back cavity.The utility model, which changes conventional turbocharger, improves the method for oil leak, the impeller back cavity on the outside of sealing ring is introduced by newly-designed conduction hole by high pressure gas in the high-pressure chamber by supercharger outlet, to prevent machine oil from oil pocket toward external leakage.
Description
Technical field
The utility model is related to turbo-charger technical field, especially a kind of oil-leakage-prevention turbocharger.
Background technology
The main reason for booster oil leak is the phenomenon of the failure of generally existing in booster, oil leak is as follows：Booster seals
Oil pocket engine oil pressure is more than gas pressure in the impeller chamber back body of outside and causes on the inside of ring.The previous oil leak main path that solves is to increase
It encrypts seal ring quantity or reduces sealing ring fit clearance, bring the increase of manufacturing cost, and can not thoroughly avoid.
Utility model content
The utility model is directed to deficiency in the prior art, provides a kind of oil-leakage-prevention turbocharger, changes tradition
The method that turbocharger improves oil leak, passes through newly-designed drainage by high pressure gas in the high-pressure chamber by supercharger outlet
Hole introduces the impeller back cavity on the outside of sealing ring, to prevent machine oil from oil pocket toward external leakage.
In order to solve the above technical problems, the utility model is addressed by following technical proposals：A kind of leakproof oil impeller
Booster, including booster ontology, the booster ontology include compressor high-pressure chamber and impeller back cavity, the pressure
It is interconnected by opening up a conduction hole between mechanism of qi high-pressure chamber and impeller back cavity.
Preferably, in above-mentioned technical proposal, the booster ontology further includes having oil pocket, and the oil pocket opening is provided with
Several sealing rings.
The utility model has the beneficial effects that：The utility model, which changes conventional turbocharger, improves the method for oil leak, leads to
It crosses high pressure gas in the high-pressure chamber by supercharger outlet and introduces the impeller back on the outside of sealing ring by newly-designed conduction hole
Cavity, to prevent machine oil from oil pocket toward external leakage.
Description of the drawings
Fig. 1 is utility model diagram.
Fig. 2 is the utility model conduction hole schematic cross-section.
Specific implementation mode
The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：Referring to Fig. 1 and Fig. 2,
A kind of oil-leakage-prevention turbocharger, including booster ontology 1, the booster ontology 1 include compressor high-pressure chamber 2 and leaf
Take turns back cavity 3, between the compressor high-pressure chamber 2 and impeller back cavity 3 by open up one conduction hole 4 by it is mutual
Connection.
The booster ontology 1 further includes having oil pocket 5, and 5 opening of the oil pocket is provided with several sealing rings.
Several groups automated cleaning structure is provided on 4 inner wall of the conduction hole, the automated cleaning structure includes that fixation is set
It sets the convex block 61 on 4 inner wall of the conduction hole, the spring 62 being connected with the convex block 61 and matches with the spring 62
The cleaning block 63 of connection is closed, slidably connects sliding block 64 on 4 inner wall of the conduction hole, the cleaning block is movably connected in the cunning
On block, when cleaning block is moved with air-flow, only one end abuts against with conduction hole inner wall and is cleaned, and the other end tilts, with drainage
Hole inner wall does not contact so that on the one end tilted the booty that adheres in moving process by airflow influence Automatic-falling, reach
To the automatically cleaning effect of cleaning block, ensure that automated cleaning structure can be used effectively for a long time.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to aforementioned reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to preceding
The technical solution recorded in each embodiment is stated to modify or equivalent replacement of some of the technical features；And these
Modification or replacement, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
