Abstract

The invention provides an overall structure and overall performance design monitoring method for an air-cooled high parameter steam turbine. The overall performance of the air-cooled high parameter steam turbine is optimized, improved and monitored by designing the overall structure of the air-cooled high parameter steam turbine. If the design of the overall structure and the overall shafting dynamic characteristics of the air-cooled high parameter steam turbine is unqualified, the overall performance of the air-cooled high parameter steam turbine is under control by optimizing and improving the overall structure, a bearing form or a rotor structure in a designing stage, using the overall structure which meets a requirement and a bearing which is higher in stability, or optimizing the geometric dimension of the rotor structure, so that the technical effects of controlling and optimizing the overall performance of the air-cooled high parameter steam turbine is achieved by using a designmonitoring system for the overall structure, flow rates of all levels, and the overall shafting dynamic characteristics.

Description

technical field [0001] The invention relates to an overall structure and an overall performance design and monitoring method of an air-cooled high-parameter steam turbine, belonging to the technical field of steam turbines. Background technique [0002] To build a thermal power plant in a water-scarce area, it is necessary to use an air-cooled high-parameter generator set. Its technical feature is that the water consumption is 25% of that of a wet-cooled generator set, and the water-saving effect is very significant. For air-cooled high-parameter generator sets, boilers, generators, and air-cooling systems can use existing products, and only air-cooled high-parameter steam turbines are new products. [0003] If the overall structure and overall performance design of new air-cooled high-parameter steam turbine products are "inherently deficient", it is quite difficult to manufacture an air-cooled high-parameter steam turbine with excellent thermal performance and high safety....
