Abstract
Disclosed is a pressure centrifugal blower for transporting gas, comprising a shell unit, an impeller unit, an air intake cover plate unit, a sealing unit, a main shaft, a driving unit, a shaft coupling, a motor and a frame. The utility model is characterized in that the sealing unit includes a sealing unit shell fixedly connected with the shell of the blower; soft fillers are filled between the sealing unit shell and the main shaft; a gland bush is sleeved on the main shaft, the rear end cover of the gland bush is fixedly connected with the sealing unit shell and the front end cover is positioned at the bottom of the blower shell and is contacted with the soft fillers; a lube fitting is arranged on the sealing unit shell, communicated with the soft fillers and with the main shaft; an oil cup is added in the lube fitting. The main improvement in the utility model is the sealing structure of the blower and in the sealing structure, the gland bush is adopted to tightly and axially compact the fillers to ensure the fillers to be in radial plastic deformation for tightly blocking the clearances, thereby a tight sealing effect is created. The lube fitting is arranged on the sealing unit shell and is communicated with the fillers which are lubricated by oil feeding, thereby the sealing system is kept in well seal, the shaft is less abraded and the power consumption is reduced.
Description
Technical field
The utility model relates to blower fan structure, particularly the pressurization centrifugal blower of conveying gas.
Background technique
The pressurization centrifugal blower of conveying gas is made up of casing group, impeller sets, air intake cover plate group, sealing group, main shaft, transmission group, coupling, motor and frame.Sealing group is in order to prevent coal gas main shaft and blower fan rear side rotational engagement place reveals and coal gas is revealed along main shaft when the equipment operation.As the patent No. is 00208078.8 disclosed a kind of boosting centrifugal blower of carrying coal gas, and the structure of this patent sealing group adopts the air exhausting type dynamic seal apparatus.This mode of structure is more complicated still, uses more complicated.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of pressurization centrifugal blower of conveying gas, and sealing configuration is simple, and it is convenient to change, and sealing is tight.
The pressurization centrifugal blower of conveying gas of the present utility model, comprise casing group, impeller sets, air intake cover plate group, sealing group, main shaft, transmission group, coupling, motor and frame, it is characterized in that sealing group comprises the sealing group shell of fixedlying connected with the blower casing, fill stuffing box packing between shell and the main shaft, gland is enclosed within on the main shaft, thereafter end cap is fixedlyed connected with the sealing group shell, and the front end of gland is positioned at outer casing bottom and contacts with stuffing box packing.
The utility model mainly is the sealing configuration that has improved blower, and sealing configuration adopts gland with the filler axial compression, makes it produce radial plastic deformation, and stifled close gap produces tight sealing effect.
On the sealing group shell, preferably have fuel filler neck and communicate with soft packing and lead to main shaft, acquire a lubricating cup in the fuel filler neck.Fuel filler neck is set on the sealing group shell communicates, filler is lubricated, make sealing system keep good sealing property, and reduce the wearing and tearing of axle, reduce power consumption by refueling with filler.
Soft packing is preferably adopted in described stuffing box packing, as natural fibre such as cotton, fiber crops; Mineral fibre such as asbestos, Expanded graphite.
Other structural type of the present utility model can be as known technology.
Advantage of the present utility model:
Sealing configuration is simple, and cost is low, makes simply, and it is convenient to change, and has good sealing effect, and the gas leakage amount obviously reduces, and has reduced the wearing and tearing with main shaft, has reduced power consumption.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is one of sealing configuration enlarged diagram;
Fig. 3 is two of a sealing configuration enlarged diagram;
Among the figure: 1 air intake cover plate group, 2 casing groups, 3 impeller sets, 4 sealing group, 5 transmission groups, 6 coupling, 7 motors, 8 frames, 9 casings, 10 sealing group shells, 11 lubricating cups, 12 fuel filler necks, 13 glands, 14 soft packings, 15 main shafts
Embodiment
As Fig. 1 is overall structure connection diagram of the present utility model, same with known technology.Mainly comprise casing group 2, impeller sets 3, air intake cover plate group 1, sealing group 4, main shaft 15, transmission group 5, coupling 6, motor 7 and frame 8.
Shown the structure of sealing group among Fig. 1 respectively as Fig. 2, Fig. 3.
Fig. 2 is the situation of band lubricating cup.Sealing group shell 10 is affixed with casing 9, fill soft packing 14 between shell 10 and the main shaft 15, gland 13 is enclosed within on the main shaft, thereafter end cap is fixedlyed connected with sealing group shell 10, the front end of gland is positioned at outer casing bottom and contacts with soft packing 14, have fuel filler neck 12 on the sealing group shell 10 and communicate with soft packing and lead to main shaft 15, acquire a lubricating cup 11 in the fuel filler neck.By finding out among the figure, the front end of gland has certain taper, and is tightr to compressing of filler.
Adopt gland 13 with soft packing 14 axial compression, make it produce radial plastic deformation, stifled close gap produces tight sealing effect.By lubricating cup 11 oiling in fuel filler neck soft packing is lubricated, makes sealing system keep good sealing property, and reduce the wearing and tearing of axle, reduce power consumption.
Fig. 3 is not for the situation of lubricating cup.Its mode of structure is identical with Fig. 2 except fuel filler neck and lubricating cup.
Claims (3)
