Abstract
The utility model proposes a kind of improved generator outlet sleeve pipe of sealing, further comprise locating ring, spring and the support ring being successively set in the gap that porcelain vase one end is formed with conducting rod, the contact surface of the locating ring and the porcelain vase is provided with flat seal, the contact surface of the locating ring and the conducting rod is provided with radial seal, and the support ring contacts with conducting rod periphery；The spring and support ring abut against the locating ring.
Description
Technical field
The utility model belongs to engine health field.
Background technology
Outgoing line porcelain bushing pipe is the important component for guiding to generator unit stator electric current outside machine from generator.Except should be able to bear
Outside certain Hydrogen Vapor Pressure, high voltage, high current and the superperformance with sealing, antivibration and protection against the tide should be able to be also born.
The problem of structure design, seal member material properties and porcelain vase quality etc., generator be present in existing outlet casing tube
Has there is oil leak, leakage hydrogen phenomenon in a part of outlet casing tube of group.Found when thread casing is checked during generator overhaul, in sleeve pipe
Portion's sealing gasket aging is serious, long-pending oil is more.
Existing outgoing line porcelain bushing seal of tube pad uses nitrile rubber pad, and Seal Oil has corrosiveness to it；And conducting rod
With respect to easily causing under porcelain bushing shell misalignment, seal is poorly sealed, and then the economy such as oil leak, leakage hydrogen occurs in acceleration generator
Property and safety issue.
The content of the invention
In order to solve the problems, such as existing outlet casing tube oil leak, leakage hydrogen and security difference, outlet casing tube pair of the present utility model
Flat seal, the sealing structure of radial seal are improved, and irrigate fluid sealant in the gap of conducting rod and porcelain vase.
The utility model provides a kind of improved generator outlet sleeve pipe of sealing, and in particular to following scheme.
A kind of improved generator outlet sleeve pipe of sealing, including porcelain vase and conducting rod, it is characterised in that also include successively
Locating ring, spring and the support ring being arranged in the gap that porcelain vase one end is formed with conducting rod, the locating ring and the porcelain vase
Contact surface be provided with flat seal, the contact surface of the locating ring and the conducting rod is provided with radial seal, described
Support ring contacts with conducting rod periphery；The spring and support ring abut against the locating ring.
Further, the support ring and the contact surface of conducting rod periphery are provided with ring seal.
Further, the seal hydrogenates nitrile rubber and/or fluorubber for high full close.
Moreover, the fluid sealant of semifluid shape is irrigated between the other end and conducting rod of the porcelain vase.
Particularly, what is irrigated between porcelain vase and conducting rod is uncured semifluid shape TITESEAL fluid sealants.And this
The porcelain vase of the outlet casing tube of utility model is accurate using physical dimension, form and position tolerance, the high import porcelain vase of grinding surface precision.When leading
When electric pole produces extension or shunk, in the regime of elastic deformation of spring, there are enough compressions to above-mentioned sealing structure, so as to protect
Demonstrate,prove sealing structure sealed reliable.
Below in conjunction with the accompanying drawings the utility model is further illustrated with specific embodiment.
Brief description of the drawings
Fig. 1 is the schematic diagram of existing steam turbine generator outlet casing tube.Wherein, porcelain axially it has been sequentially arranged along conducting rod
Bottle, flat seal ring, radial direction seal ring and its fixed mechanism.
Fig. 2 is schematic diagram of the present utility model.Wherein, fluid sealant is irrigated between porcelain vase and its conducting rod accommodated；Plane
Seal, radial seal, spring and support ring further form the sealing structure that flexible and floating seal can be achieved.
Embodiment
Outlet casing tube of the present utility model is improved to the sealing structure of flat seal, radial seal, and is being led
The gap of electric pole and porcelain vase irrigates fluid sealant.Specifically as shown in Figure 2.
The improved generator outlet sleeve pipe of sealing of the present utility model, including porcelain vase and conducting rod, the front end of porcelain vase and
The front end of conducting rod is wrapped together, and forms a gap.It is disposed with the gap that porcelain vase one end is formed with conducting rod
Locating ring, spring and support ring, the contact surface of the locating ring and the porcelain vase are provided with flat seal, the locating ring and
The contact surface of the conducting rod is provided with radial seal, and the support ring contacts with conducting rod periphery；The spring and supporting
Circle abuts against the locating ring.As shown in Fig. 2 flat seal, radial seal further form sealing structure, spring and
Support ring can make the sealing structure realize flexible and floating seal.The flat seal of the sealing structure, which is located at, fluid sealant perfusion
The end in gap that is formed of porcelain vase and conducting rod, the flat seal gap and fluid sealant therein；The radial seal supports
Position the locating ring of the flat seal, radial seal locating ring and the contact area of conducting rod periphery.And in the supporting
Circle and the contact surface of conducting rod periphery are provided with ring seal.Seal of the present utility model hydrogenates nitrile rubber for high full close
And/or fluorubber.
Moreover, the fluid sealant of semifluid shape is irrigated between the other end and conducting rod of the porcelain vase.The utility model outlet
The fluid sealant irrigated between the porcelain vase and conducting rod of sleeve pipe is uncured semifluid shape TITESEAL fluid sealants, is replaced with it
Existing yielding rubber garden structure, there is reliable vibration-damping function and good sealing property.
Because spring and support ring are against above-mentioned sealing structure, when load changes in generator operation, conducting rod leads to
When the electric current crossed also changes therewith, conducting rod, which produces, to be upheld or shrinks, and this caused stress can be absorbed by spring, in bullet
In the regime of elastic deformation of spring, still there are enough decrements to above-mentioned sealing structure, so as to ensure its sealed reliable.
The porcelain vase of the utility model outlet casing tube uses import porcelain vase, and the inherent quality of porcelain vase is good, and physical dimension, morpheme are public
Poor accurate, grinding surface required precision is high, and the overall sealing performance of outlet casing tube improves.
The inside and outside connection size of the utility model outlet casing tube and existing two generation 300MW steam turbine generator connection size
It is identical.Novel wire-outgoing sleeve pipe can directly change old-fashioned outlet casing tube, and inside and outside electric connecting part is not required to make any change
More.
The utility model is greatly improved by improving generator outlet sleeve pipe, engine health, security reliability application
Significant effect.With the change of generator load, the conducting rod retractable of outlet casing tube, the demand of peak load regulation is adapted to.
Collapsible structure can remain good sealing property with floating seal under generator difference operating mode, improve unit operation
Reliability.New construction, new diseases, extend the service life of outlet casing tube and its seal, and safety benefit is especially bright
It is aobvious.
