Bulk installation method of small steam turbine driving synchronous generator

Abstract

The invention discloses a bulk installation method of a small steam turbine driving a synchronous generator. The bulk installation method comprises the following steps of installing the steam turbine, installing the generator and installing a regulating protection system, wherein the steam turbine is installed by the following steps of (a) foundation lineation, treatment and no-parallels installation of a base, (b) detection and installation of a bedplate bracket, a bearing box and a lower cylinder body, (c) installation of a condenser, (d) installation of a gland sealing sleeve, a guide vane ring, a partition, a partition sleeve and a steam chamber, (e) installation of a rotor, (f) first installation of a regulating steam valve on the upper half part of steam, and simultaneous installation of both, (g) check of parameters before the steam turbine is covered, (h) covering of the steam turbine and (i) secondary grouting; the generator is installed by the following steps of (a) installation of a bearing seat and (b) installation of a main body of the generator; the regulating protection system is installed by the following steps of (a) installation of a regulating system and (b) installation of a protection system. The bulk installation method has the beneficial effects that vibration and noise caused by equipment operation are greatly reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to an installation method, in particular to a bulk installation method of a synchronous generator driven by a small steam turbine. Background technique [0002] Large domestic chemical, petroleum, steel and other enterprises that use a lot of steam must have their own large and medium-sized boilers to produce enough steam to maintain their production. Both the production and usage of steam fluctuate greatly. In order to maintain the normal production of enterprises, the steam production of each enterprise is often greater than its consumption, thus generating a large amount of residual steam. Improper handling of these residual steam will cause a lot of energy waste. Recovering waste steam and using it for "waste heat power generation" is a common method for large and medium-sized enterprises, so all large and medium-sized chemical, petroleum, and steel companies have their own waste heat power plants. These power plants are com...
