Abstract
A kind of sealer of gear centrifugal turbo-compressor, it is the labyrinth seal axle sleeve composition on mill pinlon axle primarily of the sealer main body be arranged on volute body and hot jacket, described sealer main body adopts steel to make the middle annular body with endoporus, at the endoporus wall top pouring babbit layer of described sealer main body by machining car; Described labyrinth seal axle sleeve hot jacket on mill pinlon axle, labyrinth seal axle sleeve collar wall is wherein shaped with sealing tooth by machining car and with the minimum Spielpassung of described babbit layer, thus form mazy type labyrinth seal; The utility model, owing to have employed Babbitt, under the prerequisite ensureing machine safe operation, significantly can reduce seal clearance, decreases the amount of leakage of machine, greatly improve the performance of machine, reach the object of energy-conserving and environment-protective.
Description
Technical field
The utility model relates to a kind of sealer of gear centrifugal turbo-compressor, belong to a kind of dynamic technical field of mechanical.
Background technique
In prior art, the Large Gear Shaft During of gear centrifugal turbo-compressor connects with motor, makes mill pinlon reach design speed by gearwheel and mill pinlon tooth-like cooperation.Impeller is connected in mill pinlon axle head and carries out work done to working gas medium, and gas obtains supercharging and speedup, and the gas of discharging from impeller continues through Diffuser, spiral case, and speed reduces, and pressure improves further.Due to the rising of air pressure, certainly exist the leakage of gas to atmosphere environment.Therefore, labyrinth seal device is set between volute body and mill pinlon axle to reduce leakage rate.Existing labyrinth seal device is overall structure, adopt copper material truck to make sealing tooth, but the price of copper is more expensive, adds the manufacture cost of product; Or employing veneering type, but add manufacture difficulty; Simultaneously due to material, the seal clearance of both can not reach higher requirement.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of improvement, manufacture cost can be reduced and significantly reduce the sealer of the gear centrifugal turbo-compressor of seal clearance.
The purpose of this utility model has been come by following technical solution, a kind of sealer of gear centrifugal turbo-compressor, it is the labyrinth seal axle sleeve composition on mill pinlon axle primarily of the sealer main body be arranged on volute body and hot jacket, described sealer main body adopts steel to make the middle annular body with endoporus, at the endoporus wall top pouring babbit layer of described sealer main body by machining car; Described labyrinth seal axle sleeve hot jacket on mill pinlon axle, labyrinth seal axle sleeve collar wall is wherein shaped with sealing tooth by machining car and with the minimum Spielpassung of described babbit layer, thus form mazy type labyrinth seal.
The utility model is further: the end face outside of described sealer main body is provided with axial screw, inner side end is provided with table top ring is installed, sealer main body utilizes described installation table top ring to be plugged in the axis hole of volute body, be axially fixed on the sidewall of volute body by bolt, and on shaft hole inner wall surface of contact, be embedded with at least two seal rings be arranged side by side, and in sealer main body between two seal rings radial be provided with at least two circumferentially, radial seal air-flow path.
The utility model greatly reduces seal clearance, reduces leakage rate, improves the overall performance of machine, reaches the object of energy-conserving and environment-protective; Meanwhile, it also greatly reduces cost of material, reduces the manufacture difficulty of product.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model structure and installation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, the sealer of a kind of gear centrifugal turbo-compressor described in the utility model, primarily of the sealer main body 2 be arranged on volute body 1 and hot jacket, the labyrinth seal axle sleeve 4 on mill pinlon axle 3 forms for it, described sealer main body 2 adopts steel to make the middle annular body with endoporus by machining car, has babbit layer 5 in the endoporus wall top pouring of described sealer main body 2; Described labyrinth seal axle sleeve 4 hot jacket on mill pinlon axle 3, labyrinth seal axle sleeve 4 collar wall is wherein shaped with sealing tooth 6 by machining car and with the minimum Spielpassung of described babbit layer 5, thus form mazy type labyrinth seal.
Shown in figure, the end face outside of described sealer main body 2 is provided with axial screw 7, inner side end is provided with table top ring 8 is installed, sealer main body 2 utilizes described installation table top ring 8 to be plugged in the axis hole of volute body 1, be axially fixed on the sidewall of volute body 1 by bolt, and on shaft hole inner wall surface of contact, be embedded with at least two seal rings be arranged side by side 9, and in sealer main body 2 between two seal rings 9 radial be provided with at least two circumferentially, radial seal air-flow path 10.
Embodiment: concrete working process is: first car becomes sealer main body, then babbitting layer; Last at mill pinlon relevant position hot jacket axle sleeve, car goes out to seal tooth; Concrete preparation process has: sealer main body manufactures: go out sealer main body with steel car, then at endoporus babbitting; The processing of sealing tooth: by the axle sleeve hot jacket with surplus on the corresponding position of mill pinlon axle, then car goes out to seal tooth.
