Abstract

The invention belongs to the technical field of gas turbines, and particularly relates to a rotor heating device of a modular rotor experiment table, which comprises a lifting bolt, a modular end door, a temperature sensor, a binding post, a box body, a bolt, a heating coil, a hinge and a pin, the number of the lifting bolts is four, and the lifting bolts are installed at the four corners of the top of the box body respectively. The heating coil is arranged in the box body, and the two ends of the heating coil are connected with the two binding posts penetrating through the box body respectively. The box body is provided with a heat preservation layer, and the temperature sensor is arranged at the top of the box body and penetrates through the box body and the heat preservation layer. The number of the modularized end doors is four, the modularized end doors are installed on the box body through hinges and pins respectively, and the two modularized end doors on the same side are provided with bolts respectively. The bottom of the box body is provided with a positioning groove used for connecting a rotor experiment table. The heating device can be modularly modified according to the characteristics of the heated rotor, and has the advantages of low cost, convenience in installation, safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of gas turbines, and in particular relates to a rotor heating device of a modular rotor test bench. Background technique [0002] The design and development of gas turbines is the bottleneck restricting the development of my country's aviation industry and gas-fired power generation. As the core component of the gas turbine, the rotor system works in a high temperature environment for a long time. At present, the relevant rotor test benches on the market are mainly aimed at the general dynamic characteristics of the rotor, ignoring the dynamic analysis of the rotor in the thermal field, which seriously restricts the experimental verification of the relevant rotor dynamic theory. Therefore, it is of great significance to carry out the research on the dynamic characteristics of the rotor in the thermal field to improve the theory of rotor dynamics. If only a special thermal analysis rotor test bench is devel...

Problems solved by technology

If only a special thermal analysis rotor test bench is developed, not only the design period is long, the construction cost is high, but also the original rotor test bench is wasted.
