Water diversion annular trough type water outlet bearer

Abstract

The invention discloses a water diversion annular trough type water outlet bearer. Two brackets, a left water discharging pipe and a right water discharging pipe are mounted below a lower water diversion annular guiding chamber. The left water discharging pipe and the right water discharging pipe are communicated with the inner part of the lower water diversion annular guiding chamber. A left lower end cap with a left lower water guiding annular trough and a right lower end cap with a right water guiding annular trough are respectively fixed to the left side and the right side of the lower water diversion angular guiding chamber. A large shaft is arranged above the inner diameters of the left lower end cap and the right lower end cap. A left upper end cap with a left upper water guiding annular trough and a right upper end cap with a right upper water guiding annular trough are respectively fixed to the left side and the right side of an upper water diversion annular guiding chamber. The upper water diversion annular guiding chamber is arranged above the lower water division annular guiding chamber. The upper water diversion annular guiding chamber is fixed to the lower water diversion annular guiding chamber by means of coupling bolts. The upper water diversion annular guiding chamber and the lower water diversion annular guiding chamber are respectively provided with a sharp water diversion semi-ring. The water diversion annular trough type water outlet bearer can be widely applied in the field of a water-cooled steam turbine generator.

Description

Technical field: [0001] The invention mainly relates to a water receiving device on the water outlet of a water-cooled steam turbine generator. Background technique: [0002] At present, the water-cooled turbine generator adopts a flat plate on the water outlet support on the water outlet. The static and dynamic sealing structures of the left and right end covers are relatively simple, and there is a gap between the inner diameter of the left and right end covers and the outer diameter of the main shaft. With a certain amount of clearance, the cooling water flowing out of multiple water outlets will impact on the arc flat plate and side wall of the water outlet support at high speed under the action of the centrifugal force of 3000 rpm of the main shaft, causing severe fogging of the cooling water The water mist will overflow from the gap between the outer diameter of the large shaft and the inner diameter of the left and right end caps, which will seriously affect the operation ...

AI Technical Summary

Problems solved by technology

[0002] At present, the water-cooled turbogenerator water outlet adopts a flat plate inside the arc on the water outlet support, and the dynamic and static sealing structures of the left and right end covers are relatively simple, and there is still a gap between the inner diameter of the left and right end covers and the outer diameter of the large shaft. With a certain gap, the cooling water flowing out of multiple water outlets will hit the circular arc plate and side wall on the water outlet support at high speed under the centrifugal force of 3000 r / min of the large shaft, causing severe fogging of the cooling water As the volume expands, the water mist will overflow from the gap between the outer diameter of the large shaft and the inner diameter of the left and right end covers, which will seriously affect the operation safety of the generator. outlet support
