Integrated process method of host heel block and ventilating box

Abstract

The invention discloses an integrated process method of a host heel block and a ventilating box. According to electric generator structure features of a large air cooling steamer and ventilating cooling performance requirements of a type experiment, an integrated structure design is performed on the host heel block used by the type experiment and the ventilating box, a steamer electric generator,a cooler, the host heel block, a wind shield, a wallboard and a supporting beam are utilized to construct a fully enclosed self-circulation ventilating system of the electric generator of the coolingsteamer, the supporting stability requirements of a stator are met, the problem that the requirements to the ventilating cooling performance of the electric generator of the cooling steamer are high is solved, and it is finally ensured that the type experiment data of the electric generator of the steamer is accurate and reliable.

Description

technical field [0001] The invention relates to a new technological method for integrating a main block and a ventilation box of a large-scale air-cooled turbogenerator type test. Background technique [0002] The type test of the air-cooled turbogenerator follows the traditional general assembly process method. Four traditional main engine blocks are placed on the final assembly test platform, the stator is installed on the main engine block, and the traditional ventilation box is made under the stator. The traditional ventilation box is placed Small coolers to simulate power plant unit ventilation systems. The traditional scheme is suitable for the type test of a small air-cooled turbogenerator, and the length of the cooler needs to be smaller than the span of the main engine block. With the continuous improvement of the capacity of air-cooled turbo-generator units, large-scale air-cooled turbo-generators have higher requirements for ventilation and cooling performance, u...

Problems solved by technology

With the continuous improvement of the capacity of air-cooled turbo-generator units, large-scale air-cooled turbo-generators have higher requirements for ventilation and cooling performance, usually four sets of coolers are required, and the coolers have larger dimensions. According to the traditional main engine block and ventilation box Layout process method, there is space interference between the cooler and the test platform and the main engine block, and the ventilation box layout space is insufficient, which cannot meet the manufacturer's type test requirements
