The every other embodiment obtained, belong to the scope of the utility model protection.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
With reference to shown in figure 1, the utility model boiler pump sealing structure includes rotating shaft 1, axle sleeve 2, stationary ring 3, rotating ring 4, biography
Dynamic pin 5, seal ring seat 6, spring 7, spring base 8 and gland, axle sleeve 2 are socketed in the outer surface of rotating shaft 1 and axial restraint, stationary ring 3
The outer surface of axle sleeve 2 is socketed in respectively with rotating ring 4 and rotating ring 4 is pushed against and is fixed in one end of stationary ring 3, spring base 8 on axle sleeve 2,
Seal ring seat 6 is pushed against in the outer surface of axle sleeve 2, and in seal ring seat 6, the one end of seal ring seat 6 is connected trundle 5 by spring 7
Spring base 8 is connect, the other end pushes against to be located on stationary ring 3, rotating ring 4, seal ring seat 6 and spring base 8 in one end of rotating ring 4, gland,
The first O-ring seals 9 are provided between stationary ring 3 and gland, the second O-ring seals 10 are provided between seal ring seat 6 and axle sleeve 2.This
In technical scheme, gland includes the first gland 11 and the second gland 12 that mutually push against, the first gland 11 and the second gland 12 it
Between be provided with the 3rd O-ring seals 13, stationary ring 3 is graphite stationary ring.Rotating ring 4 is in operating in operation process and stationary ring 3 is in quiet
Only state, rub for a long time between the two, stationary ring 3 is mended under being acted on by the elastic force after fretting wear in spring 7 to its movement
Repay to ensure the reliability of its sealing.
From above-described embodiment as can be seen that advantage of the present utility model is:
Abrasion can compensate to ensure the reliability of sealing automatically after occurring, and postpone the generation of seal failure, prolonged boiler pump
Service life.
Specific embodiment of the utility model is described in detail above, but the utility model is not restricted to the above
The specific embodiment of description, it is intended only as example.To those skilled in the art, any equivalent modifications and substitute also all
Among category of the present utility model.Therefore, the impartial conversion made in the case where not departing from spirit and scope of the present utility model
