Abstract

The invention discloses a gas turbine cylinder support device, the support device supports a cylinder (2), the support device at least comprises a support assembly, the support assembly comprises: a support body; the first adjusting parts (12 and 14) are arranged on the supporting body, and the positions of the first adjusting parts (12 and 14) on the supporting body are adjustable; and the second adjusting part (13) is used for accommodating the adjusting displacement of the first adjusting parts (12 and 14), and the second adjusting part (13) and the air cylinder (2) are integrally designed or fixedly connected. By adjusting the supporting rigidity of the air cylinder, an adjusting means is provided for solving the vibration problem of a gas turbine operation site. And when the vibration of the rotor system does not meet the requirement, the vibration problem can be solved by adjusting the supporting rigidity without reprocessing design, so that the operation risk and cost of the gas turbine are reduced.

Description

technical field [0001] The present invention relates to a gas turbine, in particular to a cold end support assembly for an inlet cylinder of a heavy-duty gas turbine. Background technique [0002] The gas turbine uses a continuous flow of gas as the working medium, and converts the heat energy of the working medium into mechanical work through rotary power. One of the main functions of gas turbine support is to provide sufficient support rigidity for the rotor to make the dynamic characteristics of the rotor system meet the requirements. It is divided into hot end support and cold end support. The hot end support is located on the turbine side and mainly bears the turbine end components. Weight; the cold end support is arranged on both sides of the cylinder block of the intake cylinder and mainly bears the weight of the compressor end components. The support stiffness is not only related to the structural strength of the support assembly itself, but also to the distance betw...
