Problems solved by technology

[0005] The invention solves the defects of the existing steam turbine exhaust cylinder facing downwards, which causes the installation height of the steam turbine to increase, the blade shaft and the overall center of gravity of the steam turbine to move upward, and the defect of the stability to decrease, and provides an upper-row welded steam turbine condensing exhaust cylinder, facing upwards Exhaust steam, reduce the installation height of the steam turbine, lower the center of gravity, and improve the stability of the steam turbine
[0006] The present invention also solves the defects that the existing steam turbine exhausts steam downwards, the input parts to be connected need to be increased in installation height, and the observation platform needs to be set at a high place, which makes it troublesome to monitor the operation of the steam turbine, and provides an upper-row welded steam turbine condensate exhaust Cylinder, exhaust steam upwards, lower the installation height of the steam turbine, lower the installation height of the input components, and monitor the operation of the steam turbine by standing on the ground

Abstract

The invention relates to an upward exhaust type welded turbine condensing exhaust hood. The defects that as the existing turbine exhaust hood exhausts downwards, the mounting height of a turbine is raised, the whole center of gravity of a vane rotating shaft and the turbine moves up, and the stability is reduced are overcome. The upward exhaust type welded turbine condensing exhaust hood comprises an exhaust hood upper part and an exhaust hood lower part, wherein an upper exhaust opening is formed in the exhaust hood upper part, and all the components of the exhaust hood upper part and the exhaust hood lower part are spliced in a welding manner. Through upward exhaust, the mounting height of the turbine can be lowered, the center of gravity is lowered, and the turbine stability is improved; and the mounting height of an input component is lowered, so that a worker can stand on the ground to monitor the running of the turbine.

Description

technical field [0001] The invention relates to a steam exhaust cylinder of a steam turbine, in particular to an upward-discharging welded steam turbine condensing exhaust cylinder for upward steam exhaust. Background technique [0002] All steam turbine condensing units need to have a steam exhaust cylinder. For convenience, the existing steam exhaust cylinders generally have a downward steam exhaust structure. [0003] Since the exhaust outlet of the exhaust cylinder that exhausts downward faces downward, it is necessary to raise the cylinder body of the exhaust cylinder and leave enough space for the lower part of the installation, otherwise it is easy to cause no installation space for the exhaust components of the exhaust cylinder and cause installation troubles . However, after the cylinder body of the exhaust cylinder is raised, the height of the blade shaft of the steam turbine is increased, so that the rotation axis of the blade shaft is at a high position, which a...
