The bottom inside for stating housing is provided with installation portion, forms the cavity of opening between the installation portion and the main shaft, described static group
Part includes the corrugated header being installed in the cavity, is fitted on the outside of the corrugated header with the installation portion, the ripple
It is corresponding with the setting height(from bottom) of the axle sleeve on the inside of base, inclined spillway hole, the bellows are offered in the installation portion
The setting height(from bottom) of seat is less than height of the spillway hole in the cavity, and the ripple with its profiling is provided with the corrugated header
Pipe, in the bellows interference be provided with wavy spring, between the bellows and the corrugated header interference be provided with stationary ring, institute
State and form friction pair between stationary ring bottom and the swivel becket.
Specifically, the bottom bending of the axle sleeve is upwardly formed groove, the groove connects and fixes with the impeller.
Specifically, auxiliary seal ring is provided between the swivel becket and the groove.
Specifically, the bottom of installation portion described in the corrugated header end turnover clamping.
Specifically, packing ring is provided between the upper and lower ends of the wavy spring and the bellows.
Compared with prior art, the main body of beneficial effect of the utility model water pump sealing structure for water of anti-overflow hole plug
Now：Water seal leakage problem is effectively prevented by the wavy spring set in bellows；Installation of the water seal in cavity is high
Degree is less than spillway hole height, effectively avoids spillway hole blockage problem；Overall sealing structure for water strong applicability, installing space subtract
Small, stability is strong, effectively reduces water seal vibration, and work is more steady.
Brief description of the drawings
Fig. 1 is the entirety sectional view of the utility model embodiment；
Fig. 2 is the phantom of the present embodiment；
Numeral represents in figure：
1 main shaft, 2 housings, 21 installation portions, 3 impellers, 4 axle sleeves, 41 grooves, 42 swivel beckets, 43 auxiliary seal rings, 5 cavitys,
51 corrugated headers, 52 bellowss, 53 wavy springs, 54 packing rings, 55 stationary rings, 6 spillway holes.
Embodiment
Clear, complete description will be carried out to the technical scheme in the embodiment of the utility model below in conjunction with the accompanying drawings, it is clear that
Described embodiment is only the utility model part of the embodiment, rather than whole embodiments.
Embodiment：
Shown in reference picture 1-2, the present embodiment is the sealing structure for water of water pump anti-overflow hole plug, including main shaft 1, is sheathed on
Housing 2 and impeller 3 on main shaft 1.Stationary components and runner assembly are provided between housing 2 and impeller 3.Runner assembly includes being arranged
The axle sleeve 4 fitted on main shaft 1, the bottom bending of axle sleeve 4 are upwardly formed groove 41, and groove 41 connects and fixes with impeller 3, groove
Interference is provided with swivel becket 42 in 41, and auxiliary seal ring 43 is provided between swivel becket 42 and groove 41.
The bottom inside of housing 2 is provided with installation portion 21, and the cavity 5 of opening, cavity 5 are formed between installation portion 21 and main shaft 1
Interior to be provided with the stationary components being socketed on outside axle sleeve 4, stationary components include corrugated header 51, the side of corrugated header 51 and installation portion
21 fit, the bottom of its bottom turnover clamping installation portion 21.The opposite side of corrugated header 51 is relative with the setting height(from bottom) of axle sleeve 4
Should.Inclined spillway hole 6 is offered in installation portion 21, the setting height(from bottom) of corrugated header 51 is less than height of the spillway hole 6 in cavity 5
Degree.The bellows 52 with its profiling is provided with corrugated header 51, in bellows 52 interference be provided with wavy spring 53, wavy spring 53
Upper and lower ends and bellows 52 between be provided with packing ring 54.Interference is provided with stationary ring 55 between bellows 52 and corrugated header 51,
Friction pair is formed between the bottom of stationary ring 55 and swivel becket 42.
The main shaft 1 of runner assembly and water pump plays rotation, and the housing 2 of stationary components and water pump remains stationary.Waveform bullet
Spring 53 plays a part of pretension, compensation and buffering in bellows 52, there is enough resilient support swivel becket 42 and stationary ring 55
