Abstract
This invention relates to a sealing structure of a turbine booster characterizing in the sealing of a compressor: a V-type seal loop is enclosed on the outer jacket of an inner rotor shaft of a cover base, the end surface of a graphite seal loop is adhered with the supporting end surface of the rotor shaft closely, and the end surfaces of the graphite seal loop and the rotor shaft are tightly combined flexibly. A method for sealing the turbine booster includes: sealing a compressor, putting a prepared V-type rubber seal loop on an outer jacket in the cover base and binding the end surfaces of them closely and combining the surfaces of them flexibly by a low pressure spring and a spring baffle piece.
Description
Technical field
The present invention relates to a kind of turbosupercharger sealing technique, relate in particular to a kind of turbosupercharger graphite grazing structure and technological method thereof.
Background technique
Turbosupercharger is that to improve engine power and improve the effective measures of Economy also be the inevitable approach that motor is strengthened, it has become the important directions of current internal combustion engine development, be widely used for fields such as minicar and heavy truck, turbosupercharger has become one of vitals of motor, need constantly improve at aspects such as its performance and durability.The sealing configuration of turbosupercharger is to prevent that the lubricating oil of bearing support from entering the circulation part of pressurized machine, and stops the combustion gas of the air of gas compressor or turbine end to enter the lubricating oil chamber of pressurized machine, is the important step that guarantees the pressurized machine proper functioning.At present, the sealing of pressurized machine mainly contains piston ring seal, forms such as contact seal of graphite circle and lip seal.When petrol engine supercharging closure closes hour, the backside pressure of compressor impeller can be significantly less than the bearing support internal pressure, and impeller is worked under bigger condition of negative pressure, and pressure difference can be up to 80kpa, this moment, the piston type sealing configuration just can not guarantee effective seal, needed to adopt the contact seal of graphite circle.The sealing of common graphite circle is vulnerable to hot refluence phenomenon and influences adhesion to the turbine end face, and mechanical loss is big, and turbo-lag is also big.In order to guarantee higher sealability, the dual-active plug ring sealing means that adopts the structure relative complex is arranged also.In a word, sealing configuration is the weak link on the turbosupercharger always, need constantly improve, to guarantee the proper functioning of pressurized machine.
Summary of the invention
The present invention is directed to the technical problem of above-mentioned existence and a kind of simple in structure, sealability is reliable, mechanical loss is little turbosupercharger graphite grazing structure and method thereof are provided.
Seal structure of turbocharger technological scheme of the present invention is as follows:
A kind of seal structure of turbocharger, comprise turbine case, compressor impeller, it is characterized in that: the sealing of gas compressor, the V-shaped seal ring blanking cover seat inner rotor shaft of packing into puts outward, graphite-seal ring end face and rotor shaft support the gapless adhesion of end face and are connected, by soft the combining closely of end face with graphite-seal ring end face and rotor shaft of the low pressing spring that is provided with in the blanking cover seat and spring stop piece.
Turbosupercharger encapsulating method of the present invention is as follows:
Gas compressor is sealed, the V-type rubber seal of the making blanking cover seat inner rotor shaft of packing into is put outward;
Graphite-seal ring end face and rotor shaft supported end face is gapless to be adhered together,, make soft the combining closely of end face of graphite-seal ring end face and rotor shaft by low pressing spring and the spring stop piece of in the blanking cover seat, installing.
Advantage of the present invention and effect are as follows:
The turbosupercharger sealability that the present invention has overcome above-mentioned prior art existence is unreliable, be prone to the problem of leakage of oil, adopt the mode that graphite-seal ring is gap-free sealed and rubber seal is gap-free sealed, guaranteed the airtight quality of turbosupercharger, avoided oil leakage phenomenon, improved the working life of pressurized machine, made turbocharger operation in the optimum state.
Description of drawings
Fig. 1 is the schematic representation of seal structure of turbocharger of the present invention.
Fig. 2 is the side view of Fig. 1.
Among the figure: 1, V-shaped seal ring, 2, graphite-seal ring, 3, low pressing spring, 4, spring stop piece, 5, the blanking cover seat.
Embodiment
Describe the present invention in detail below in conjunction with the drawings and specific embodiments.
Seal structure of turbocharger of the present invention as shown in Figure 1, adopt the sealing means of graphite and rubber combination that gas compressor is sealed, V-shaped seal ring 1 blanking cover seat 5 inner rotor shafts of packing into put outward, graphite-seal ring 2 end faces and rotor shaft support the gapless adhesion of end face and are connected, and low pressing springs 3 by settings in the blanking cover seat 5 and spring stop piece 4 are with soft the combining closely of end face of graphite-seal ring 2 end faces and rotor shaft.
Turbosupercharger encapsulating method of the present invention is as follows:
Gas compressor is sealed, the V-type rubber seal of making 1 blanking cover seat 5 inner rotor shafts of packing into are put outward; It is to contact with blanking cover seat inner rotor shaft overcoat closely on the one hand for the V-type rubber seal, is to combine closely with the endoporus of graphite-seal ring on the other hand, plays double seal;
Graphite-seal ring 2 end faces and rotor shaft supported end face is gapless to be adhered together, by low pressing spring 3 and the spring stop piece of in blanking cover seat 5, installing 4, make soft the combining closely of end face of graphite-seal ring 2 end faces and rotor shaft, to guarantee the reliable sealing of gas compressor under the very big situation of pressure difference.
V-shaped seal ring adopts the hydrogenation butadiene acrylonitrile rubber to make, and makes point of contact gentle and can change with surface of contact.The making of graphite-seal ring requires flat and smooth and bright like a mirror of graphite surface.Adopt low pressing spring to make elastic force soft, guarantee reliable sealing.
