Fig. 2 is sectional view of the present utility model.
in figure, protecgulum 1, bonnet 2, rotor 3, rotating shaft 4, suction port 5, relief opening 6, cavity 7, axle sleeve 8, impeller 9, the first comb tooth seal ring 10, second comb tooth seal ring 11, spring bearing 12, reinforced seal ring 13, vent 14.
Embodiment
For accompanying drawing, embodiment of the present utility model is described further below:
As shown in the figure, a kind of side canal vapour compression machine, comprise protecgulum 1, bonnet 2, rotor 3, rotating shaft 4, suction port 5 and relief opening 6, described protecgulum 1 and bonnet 2 form a closed cavity 7, described rotor 3 is positioned at described cavity 7, described suction port 5 and relief opening 6 communicate with described cavity 7, described rotating shaft 4 penetrates protecgulum 1 with bonnet 2 and is connected with rotor 3, described rotor 3 comprises axle sleeve 8, impeller 9, described axle sleeve 8 is sheathed in rotating shaft 4, described impeller 9 radially direct is in axle sleeve 8 outer surface, described protecgulum 1 surface of internal cavity and the first comb tooth seal ring 10 be provided with between bonnet 2 surface of internal cavity and axle sleeve 8 outer surface along axle sleeve 8 axial distribution, described protecgulum 1, be provided with between the surface of internal cavity of bonnet 2 and impeller 9 along the radially-arranged second comb tooth seal ring 11 of impeller 9.Protecgulum 1, bonnet 2 forms airtight cavity, rotor is built in this cavity, rotating shaft penetrates bonnet successively, rotor and protecgulum, axis of rotation is rotated by axle sleeve impeller, realize the compression of air, to comb tooth seal ring 10 by arranging some seal rings in the axis of axle sleeve and form the first comb tooth seal ring 10 and arrange in the both sides of impeller the radial direction formation second that distributes successively, the section area of cavity progressively reduces between compressor inlet to exhaust outlet of compressor, compressor drum impeller rotates with certain speed in cavity, water vapour is through the Repeated Compression of impeller, finally become pressurized water steam to discharge.Lateral path compressor designed by the present invention is designed with two resealings, be first one radial direction the sealing of comb tooth and together with axial comb tooth sealing, after twice comb tooth seals, the pressure of water vapour reduces greatly.Therefore, labyrinth seal that is radial and axis is increased, to prevent the leakage of steam in impeller of rotor wheel hub.And also there is the features such as volume is little, structure simple, applying flexible.
In the utility model, be provided with spring bearing 12 between described rotating shaft 4 and protecgulum 1, bonnet 2, the rotating shaft 4 between described spring bearing 12 and axle sleeve 8 be arranged with the reinforced seal ring 13 fitted with the connection of protecgulum 1, bonnet 2.Seal at the radial direction comb tooth of lateral path compressor, on the basis of axial comb tooth sealing, then in shaft connection place, reinforced seal ring be installed, water vapour can be sealed up completely.
In the utility model, the outside of described reinforced seal ring 13 offers the uniform vent 14 of circumference.In the outside of reinforced seal ring, have several vents that circumference is uniform, steam is discharged to outside to prevent corrosion resistant support bearing through reinforced seal ring from vent.Reinforced seal ring, vent, spring bearing are all arranged in impeller bilateral symmetry, and the independence of compressor is strengthened greatly, and the adaptable condition range of compressor also just increases greatly.
In the utility model, described protecgulum 1 and bonnet 2, rotor 3 all adopt 316L stainless steel to manufacture.The protecgulum 1 made by 316L stainless steel and bonnet 2, rotor 3 effectively can deal with the corrosivity of water vapour.
Embodiment should not be considered as the restriction to model utility, but anyly done based on spirit of the present utility model
Improvement, all should within protection domain of the present utility model.
