[0002] like figure 1 As shown, the double-rotor gas turbine supercharging device includes high and low-pressure supercharging devices. The low-pressure supercharging device has always been assembled by installing multiple components on the installed gas generator one by one. Specifically, first Assemble the rotor components of the low-pressure supercharging device to the installed gas generator, and then install the stator casings of all levels, starting from the last level, to the corresponding positions one by one to complete the assembly process, but the assembly process and assembly Time is affected by gas generator assembly

Embodiment Construction
[0021] Such as image 3 As shown, the low-pressure supercharging device 1 includes a front fulcrum 6 of the rotor of the low-pressure supercharging device, a rotor 7 of the low-pressure supercharging device, a stage casing 8 of the low-pressure supercharging device 1~n-1 (n represents the total number of stages of the casing), a low-pressure supercharging device Supercharging device rotor rear fulcrum 9.
[0022] Such as figure 2 As shown, first assemble the rotor parts of the low-pressure supercharging device 1 onto the prepared assembly vehicle 3, and then install each stator casing to the corresponding position step by step starting from the last stage. After the installation is completed, the After the installation of the gas generator 5 is completed, replace the last-stage casing 2 with the last-stage process casing 4, and hoist the low-pressure booster device 1 that is replaced with the last-stage process casing 4 to the On the gas generator 5, on the gas generator 5,...

The invention discloses an assembly method of a low-pressure supercharging device used for a bi-rotor gas turbine. The assembly method comprises the following steps: assembling a rotor part of the low-pressure supercharging device (1) on a prepared assembly wagon (3) at first; then installing all stator casings at corresponding positions grade by grade from the last grade; after a gas generator (5) is completely installed, changing a last-grade casing (2) by a last-grade process casing (4); integrally hoisting the low-pressure supercharging device (1) for changing the last-grade process casing (4) on the gas generator (5) by using a special hoisting tool; replacing the last-grade process casing (4) with the last-grade casing (2), so as to complete the assembly process. According to the assembly method disclosed by the invention, the low-pressure supercharging device independently serves as a unit body and is parallel to the gas generator or is assembled in advance, thereby breaking away from the restriction of whether the gas generator is completely assembled and improving the assembly efficiency of the complete gas turbine.
Description
technical field [0001] The invention belongs to the field of fans / compressors, and in particular relates to the assembly sequence of a low-pressure supercharging device for a double-rotor gas turbine. Background technique [0002] Such as figure 1 As shown, the double-rotor gas turbine supercharging device includes high and low-pressure supercharging devices. The low-pressure supercharging device has always been assembled by installing multiple components on the installed gas generator one by one. Specifically, first Assemble the rotor components of the low-pressure supercharging device to the installed gas generator, and then install the stator casings of all levels, starting from the last level, to the corresponding positions one by one to complete the assembly process, but the assembly process and assembly Timing is affected by gas generator assembly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method ...
