A test device for a steam turbine

Abstract

The invention relates to the technical field of turbine engine manufacturing, and discloses a turbine engine trial running device. The turbine engine trial running device comprises a base and a groundbolt set; the base comprises two first base bodies for supporting the two ends of a turbine engine base plate, and a second base body for supporting the side edge of the turbine engine base plate; multiple parallel transverse strip grooves with convex sections are formed in the upper surfaces of the first base bodies; multiple parallel longitudinal strip grooves with convex sections are formed inthe upper surface of the second base body; and the ground bolt set comprises multiple first bolts slidingly connected to the first base bodies and with bolt heads inserted in the transverse strip grooves, first nuts in bolt connection to the first bolts and used for butting against the upper surface of the turbine engine base plate, multiple second bolts slidingly connected to the second base body and with bolt heads embedded in the longitudinal strip grooves, and second nuts in threaded connection with the second bolts and used for butting against the upper surface of the turbine engine baseplate.

Description

technical field [0001] The invention relates to the technical field of steam turbine manufacturing, in particular to a test run device of a steam turbine. Background technique [0002] The steam turbine test run is to check the design, manufacture and construction quality through the whole process of start-up, speed up, constant speed, load and shutdown, to judge whether the parameters such as vibration, temperature and pressure are qualified, and whether each system can work normally; among them, the steam turbine is also called The steam turbine engine is a rotary steam power device. The high-temperature and high-pressure steam passes through the fixed nozzle to become an accelerated air flow and is sprayed onto the blades, so that the rotor equipped with the blade row rotates and does work externally at the same time; at the same time, the steam turbine is a modern thermal power plant. The main equipment of the factory is also used in the metallurgical industry, chemical ...

AI Technical Summary

Problems solved by technology

[0004] When the steam turbine is transported to the test run site, it usually needs to be lifted by the crane before it can be moved. Then the steam turbine can be dropped on the base in the test run site after getting up and down from the drive train, and then the operator passes the bolt through the installation hole on the bottom plate of the steam turbine. And by tightening the nuts, the base of the steam turbine is fixed on the base, and the test run can be carried out; because of the different models of different steam turbines, the size of the base of the steam turbine will be different and the corresponding installation hole positions will also have corresponding differences. However, the installation position of the bolts on the base remains unchanged, so bases of different sizes may not be able to fall into the position of the bolts on the base, and finally the bottom plate of the steam turbine may not be fixed by the bolts on the base
