Hold the connection of sealing hydrocarbons fabric connectivity.
Further, further includes:
It is set to the check valve at the balance channel both ends, the check valve is used to enter balance in the pressed gas logical
Behind road, the flow for leading to calm the anger generator terminal and turbine end gas is adjusted in proportion.
Further, the press machine sealing gland circle also sets up venthole, and the venthole is connected to the annular chamber.
Further, the venthole is evenly distributed on the press machine sealing gland circle.
Further, the annular chamber is arranged inside and outside O-ring.
Turbocharger pressure gas balance system of the present invention is integrally tied not increasing other components, do not destroy booster
Structure under the premise of not influencing booster overall performance and reliability, can solve compressor wheel blade back refrigerating function and whirlpool simultaneously
The mutual onrelevant of end oil hermetic function is taken turns even to conflict mutually the problem of interfering.Axis suitable for full range of sizes
Stream, runoff booster, can cope with and without ambient pressure gas source, facilitate implementation.

Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Fig. 1 is turbocharger pressure gas balance system structure diagram of the present invention, as shown in Figure 1, the present embodiment
Structure may include:
The pressed gas for being opened in intermediate enters channel, enters the balance channel that channel is connected to the pressed gas,
Described balance channel one end connects the annular chamber of the compressor sealing gland circle for generator terminal of calming the anger, the other end and turbine of the balance channel
Hold the connection of sealing hydrocarbons fabric connectivity.
Specifically, compressor sealing gland circle is mounted on bear box pressure side side, axially pressed by bolt and bear box
It is tightly connected.By way of drilling on supporting mass, annular chamber is in communication with the outside, to guarantee that pressed gas can smooth No leakage
Ground enters annular chamber by extraneous gas source.Pressed gas enters from the gas passage of bear box, and along pressed gas balance channel
Gas distribution is carried out, a part flows to compressor end annular chamber and participates in blade back cooling, and separately some flows to turbine end and participates in whirlpool
Hold oil seal.The pressed gas at specific both ends distributes flow, according to actual needs, by the way that balance channel both ends are set in advance
Discharge area is adjusted.By the tonnage air ventilation passage on supporting mass, make pressed gas thus channel from outer
Boundary enters turbine end, participates in oil seal.
Further, further includes:
It is set to the check valve at the balance channel both ends, the check valve is used to enter balance in the pressed gas logical
Behind road, the flow for leading to calm the anger generator terminal and turbine end gas is adjusted in proportion.
Specifically, the present embodiment is calmed the anger, it is cold can to play simultaneously compressor blade back for generator terminal check valve and turbine end check valve
But function is reinforced in function and turbine end sealing, also can choose one of which and individually works.
Further, the press machine sealing gland circle also sets up venthole, and the venthole is connected to the annular chamber.
Specifically, compressor sealing gland circle and bear box cooperatively form a circle annular chamber, the uniform cloth of compressor sealing gland circle
It sets and tiltedly bores a collar aperture, annular chamber is connected to compressor impeller blade back chamber.And by securing member by compressor sealing gland circle and
Bear box is pressed together to form annular chamber, and flowing to compressor end pressure gas will assemble in annular chamber, by inside and outside two
Road seal O-ring guarantees that pressed gas does not leak, and gas flows along circumferential direction, is passing through one week uniform cloth of compressor sealing gland circle
After the through-hole set, into and be applied directly to compressor impeller blade back high-temperature region, so that surface high-temp area temperature is dropped to ideal model
In enclosing, achieve the purpose that blade back is cooling.Under the premise of having ambient pressure gas source, blade back refrigerating function is not needed such as, then is only needed
The generator terminal that will calm the anger one-way check valve is thoroughly closed or compressor sealing gland circle is evenly arranged drilling and does not process, or stifled with technique
Extremely, pressed gas can not flow into generator terminal of calming the anger, and can only fully enter turbine end and participate in sealing.
Under the premise of no ambient pressure gas source, blade back refrigerating function is not needed such as, then the generator terminal that needs will to calm the anger is unidirectionally non-return
Valve is thoroughly closed, or installs screw plug sealing additional in the starting point that pressed gas enters channel, prevents bear box gas leakage.Booster
The pressed gas that compressor impeller itself generates when work will be evenly arranged by compressor sealing gland circle drills into annular chamber,
Whirlpool end is entered by pressed gas balance channel again and participates in sealing.
Further, the venthole is evenly distributed on the press machine sealing gland circle, and the venthole opens direction
It should be in the same direction with impeller direction of rotation.
Specifically, the direction of opening of the present embodiment venthole further increases cooling with impeller direction of rotation in the same direction
Efficiency.
Further, the annular chamber is arranged inside and outside O-ring.
Specifically, annular chamber is by inside and outside twice O-ring radial seal.Guarantee that cavity pressure gas will not flow out.
The present invention has the advantages that traditional compressor blade back cooling technology and turbine end bleed sealing structure are integrated into
The novel pressure gas balance system structure of integral type, can play compressor blade back refrigerating function simultaneously and turbine end sealing adds
Powerful also can choose one of which and individually work.This system structure depend on original TC bearings shell with
Oil-gas seal structure is not further added by new components, does not have an impact to the performance of booster and reliability.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
