Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
As shown in Figure 1 to 9, the sealing device of this high pressure blower of the utility model, including blower body 10 and blower
Lid 11 further includes the retainer plate 12 for fixing fan cover 11.Blower body 10 is to place impeller, and fan cover 11 is for covering wind
Body 10,10 rear end of blower body is equipped with axis hole 13, for placing axis.Retainer plate 12 is fixed on blower body 10 by bolt 14,
And fan cover 11 is to cover on blower body 10, and a part of fan cover 11 is mounted in retainer plate 12, passes through bolt 14
Retainer plate 12, fan cover 11 and blower body 10 is fixed.
Mounting portion 15 is equipped on blower body 10, mounting portion 15 is a part to extend out on blower body 10, is used for
11 sets of fan lid above, and for placing bearing block on impeller.11 sets of fan cover on mounting portion 15.In fan cover
11 are equipped with extension 16, and for extension 16 in the side of fan cover 11, extension 16 is equipped with sliding part 17, sliding part 17 with prolong
Long portion 16 is vertical.Sliding groove 18 is equipped in retainer plate 12, sliding groove 18 slides wherein for sliding part 17.In sliding groove 18
Equipped with blocking portion 19, blocking portion 19 prevents sliding part 17 from skidding off for stopping sliding part 17.Extension 16 and sliding part 17 are all pacified
In sliding groove 18, the height of sliding part 17 is matched with the height of sliding groove 18, can be smoothly in sliding groove 18
Sliding, while there are gap between blocking portion 19, which is to place extension 16, thickness and the extension 16 in gap
Thickness matching can slide wherein.
It is the first fan cover 111 and the second fan cover 112 respectively preferably, fan cover 11 is to consist of two parts, first
Fan cover 111 and the second fan cover 112 are combined into an integral installation in retainer plate 12.And fan cover 11 arrives retainer plate 12
The distance between be extension 16, be to guarantee that two fan covers can be opened there are a certain distance.It why is setting two
A half of fan cover is in order to which preferably fan cover 11 is mounted on the mounting portion 15 of blower body 10.
It is equipped with seal groove 20 on mounting portion 15, places sealing ring 21 in the seal groove 20.In seal groove 20
Equipped with several ellipsoidal surfaces 201, why ellipsoidal surface 201 is set, be because being equipped with oval lug boss 22 on sealing ring 21,
