Description
Technical field
This utility model relates to technical field of mechanical, particularly a kind of boiler feedwater discharge pump mechanical seal device, mainly
Boiler for power industry.
Background technology
At present, extensively in power industry, be usually used in common in rinse for single end face multiple-spring mechanical seal device,
But the rubbing surface cooling effect of this device is not fine, and being the most axially difficult to regulation, therefore, using effect is less
Preferable.
Utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, it is provided that a kind of boiler feed pump is with single-ended
Face integrated mechanical sealing device, is mainly used in metal bellow type boiler feed pump, its novel structure, and using effect is good, increases
Add the service life of mechanical seal.
The technical solution adopted in the utility model is such that
A kind of boiler feed pump single-end face integrated mechanically-sealing apparatus, including rotating shaft, axle sleeve, graphite stationary ring, rotating ring,
Socket-welding fitting and air bleeding valve, described axle sleeve is socketed in rotating shaft outer surface axial restraint, and described graphite stationary ring is socketed in axle
Set outer surface, described moving ring sleeve is connected on graphite stationary ring outer surface and the left side of rotating ring and graphite stationary ring is axially fixed in axle sleeve
On, described socket-welding fitting is arranged on rotating ring with air bleeding valve and connects with rotating shaft inside, and described axle sleeve is right at graphite stationary ring
Side arranges seal ring seat, is connected corrugated tube between seal ring seat with graphite stationary ring.
As preferably, described corrugated tube two ends are provided with support fender bracket, and the support fender bracket of one end is removable with seal ring seat
Formula connects, and the support fender bracket of the other end is pushed against graphite stationary ring right-hand member by connector.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: use bellow-type expansion
Junction between rotating ring and graphite stationary ring is sealed by structure, it is ensured that medium does not leaks out, and effect is sealed than conventional machine
Many spring structures are more preferable.
Accompanying drawing explanation
Fig. 1 is left view of the present utility model.
Fig. 2 is the K-K sectional view of utility model shown in Fig. 1.
Labelling in figure: 1 is axle sleeve, 2 is seal ring seat, and 3 for supporting fender bracket, and 4 is corrugated tube, and 5 is connector, and 6 is stone
Ink stationary ring, 7 is rotating ring, and 8 is socket-welding fitting, and 9 is air bleeding valve, and 10 is rotating shaft.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in detail.
Embodiment:
As shown in Figure 1, 2, a kind of boiler feed pump single-end face integrated mechanically-sealing apparatus, including rotating shaft 10, axle sleeve
1, graphite stationary ring 6, rotating ring 7, socket-welding fitting 8 and air bleeding valve 9, described axle sleeve 1 is socketed in rotating shaft 10 outer surface and axially consolidates
Fixed, described graphite stationary ring 6 is socketed in axle sleeve 1 outer surface, and described rotating ring 7 is socketed in graphite stationary ring 6 outer surface and by rotating ring 7 and stone
Ink stationary ring 6 left side be axially fixed on axle sleeve 1, described socket-welding fitting 8 and air bleeding valve 9 be arranged on rotating ring 7 and with
The internal connection of rotating shaft 10, described axle sleeve 1 arranges seal ring seat 2 in graphite stationary ring 6 right, seal ring seat 2 and graphite stationary ring 6 it
Between connect corrugated tube 4.
Described corrugated tube 4 two ends are provided with support fender bracket 3, support fender bracket 3 and the removable company of seal ring seat 2 of one end
Connecing, the support fender bracket 3 of the other end is pushed against graphite stationary ring 6 right-hand member by connector 5.
Wherein, it is primary seal point at rotating ring 7 and the combination friction of graphite stationary ring 6, needs to ensure medium not external leakage.
In operation process, rotating ring 7 is in operating and graphite stationary ring 6 remains static, long-time friction between the two and
Maintaining sealing liquid film, graphite stationary ring 6 is moved to the left after fretting wear under the elastic force effect of corrugated tube 4 to be compensated to protect
Demonstrate,prove its reliability sealed.
After this utility model changes many spring structures of conventional machine envelope into bellow-type expansion structure, can be better protected from
The seal failure that conventional machine envelope often causes because of reason inefficacies such as spring blockings.
This utility model also adds support fender bracket on the cylindrical of corrugated tube 4, can effectively prevent the deformation of corrugated tube 4
And unstable, ensure that its reliability compensated well, thus extend the service life of machine envelope.
The material selection leaching metallic graphite carbon of graphite stationary ring 6, effectively increases the self-lubricity energy of primary seal, and can protect again simultaneously
Demonstrate,prove its relative wear resistance, thus improve service life.
