Abstract
The utility model discloses a novel steam turbine bearing box preformed hole prevention leakage oil that wears to be qualified for next round of competitions device, including bearing housing, splashproof lid, conduit, the splashproof lid is installed on the bearing housing inner wall, still installs the conduit on the bearing housing outer wall. Can thoroughly eliminate because of the lubricating oil seepage causes the major safety risks of fire incident at steam turbine high -temperature area, prevent effectively that the turbo -engine lube from passing through axle bush temperature lead -out wire seepage, improve unit and equipment safety, eliminate because of the lubricating oil seepage causes the fire incident at steam turbine high -temperature area, major safety risks that the unit non - is stopped, the security that has improved equipment.
Description
Technical field
This utility model relates to oil-impermeable device field, particularly relates to a kind of Novel steam turbine bearing housing and passes line preformed hole oil-impermeable device.
Background technology
Existing steam turbine is mounted on temperature sensor between bearing, is used for detecting thrust bearing Pasteur's coal temperature.It is arranged on its lead-out wire of temperature element (TE of tile fragment after bearing housing preformed hole passes, delivers to terminal cabinet on the spot, then delivered to DCS system by terminal cabinet through shielded cable and do temperature protection logical judgment, and then reach protection turbine bearing pad and realize the effect of tripping operation.It is original design for the ferrule fitting with external screw thread tapered configuration that existing bearing box of steam turbine temperature element (TE passes the oil-impermeable device on line preformed hole, realizes that lead-out wire is put permeability by the rubber plug rotated in the middle of the extruding of hollow nut and seals.In steam turbine long-term operation process, rubber plug at high temperature can quick aging, and then cause that the crack that lubricating oil passes through rubber plug aging is oozed out outward, if the high-temperature area that permeability is deposited in steam turbine fails to find in time and clear up, the dangerous accidents such as fire incident can be caused to occur.
Utility model content
In order to solve above-mentioned technical problem, this utility model aims to provide a kind of Novel steam turbine bearing housing and passes line preformed hole oil-impermeable device.
This utility model is achieved by following technical solution:
A kind of Novel steam turbine bearing housing passes line preformed hole oil-impermeable device, and including bearing housing, Splashproof cover, conduit, described Splashproof cover is arranged on bearing housing inwall, and bearing housing outer wall is also equipped with conduit.
It is provided with sealing gasket, Splashproof cover and sealing gasket between described Splashproof cover and bearing housing to be arranged on bearing housing by bolt.
Described conduit is half U type, and correspondence is arranged on the through wires hole place on bearing housing.
The internal diameter of described conduit is more than the internal diameter 0.5～1mm of through wires hole.
Described Splashproof cover lower end is additionally provided with through hole.
The beneficial effects of the utility model are:
Compared with prior art, a kind of Novel steam turbine bearing housing that this utility model provides passes line preformed hole oil-impermeable device, can thoroughly eliminate because of oil seepage major safety risks of initiation fire accident in steam turbine high-temperature region, it is effectively prevented turbo-engine lube by bearing bush temperature lead-out wire seepage, improve unit and device security, eliminate because of oil seepage in steam turbine high-temperature region initiation fire accident, unit is non-stop major safety risks, improve the safety of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-bearing housing, 2-Splashproof cover, 3-conduit, 4-sealing gasket, 5-through wires hole, 6-bolt, 7-through hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in required protection domain is not limited to；
As shown in the figure, a kind of Novel steam turbine bearing housing that this utility model provides passes line preformed hole oil-impermeable device, including bearing housing 1, Splashproof cover 2, conduit 3, described Splashproof cover 2 is arranged on bearing housing 1 inwall, and bearing housing 1 outer wall is also equipped with conduit 3.
It is provided with sealing gasket 4, Splashproof cover 2 and sealing gasket 4 between described Splashproof cover 2 and bearing housing 1 to be arranged on bearing housing 1 by bolt 6.
Described conduit 3 is half U type, and correspondence is arranged on through wires hole 5 place on bearing housing 1.
The internal diameter of described conduit 3 is more than the internal diameter 0.5～1mm of through wires hole 5.Making conduit 3 will not hide through wires hole 5 when being welded on through wires hole 5 place, when oil return, the difference in height between penetration pipe 5 inwall and through wires hole 5 will not stop that lubricating oil returns to bearing housing.
Described Splashproof cover 2 lower end is additionally provided with through hole 7.
Principle of the present utility model is: Splashproof cover, for stoping because of steam turbine bearing high-speed rotary then the lubricating oil splash that throws away is to bearing bush temperature lead-out wire preformed hole place, oozes out from preformed hole.Conduit makes a small amount of lubricating oil oozed out from former preformed hole again flow backwards in bearing housing under the effect of self gravitation, it is ensured that lubricating oil is completely non-leakage.
