A method for manufacturing an integrated power-generation steam turbine unit.
Assembling the steam turbine unit and the power-generation steam turbine unit separately would result in a larger overall assembly volume, a greater number of parts, and higher assembly requirements. Moreover, it would necessitate connecting the rotors via couplings for alignment; even slight deviations could lead to vibrations, preventing the rotors from reaching high speeds and thereby reducing operational efficiency. To address these challenges, technicians have developed an integrated power-generation steam turbine unit. To achieve the aforementioned objectives, this power-generation steam turbine unit employs the following technical solution...
In existing technology, a steam turbine—also known as a steam turbine engine—is a rotary steam-powered device. High-temperature, high-pressure steam passes through fixed nozzles, forming an accelerated airflow that is directed onto the blades, causing the rotor equipped with these blades to rotate and perform external work. Steam turbines are the primary equipment in modern thermal power plants and are also used in metallurgical, chemical, and marine propulsion systems. Typically, current steam turbines are assembled separately into two units: the turbine unit and the generator turbine unit. The rotors of these two units are connected via a coupling, enabling the transmission of the turbine’s torque to the generator. The turbine unit and... Power generation steam turbine unit Separate assembly results in a larger overall assembly volume, a greater number of parts, and higher assembly requirements. At the same time, it necessitates connecting the intermediate rotors via couplings; even slight misalignment can cause vibration, preventing the rotors from reaching high speeds and thus reducing operational efficiency.

Power generation steam turbine unit The technical solution adopted is as follows: an integrated power-generation steam turbine unit, comprising an integrated cylinder, a turbine sleeve rotor, a generator sleeve rotor, and a main shaft. The main shaft is installed between the integrated cylinders, while the turbine sleeve rotor and the generator sleeve rotor are sleeved onto the circumferential surface of the main shaft. Both the turbine sleeve rotor and the generator sleeve rotor are housed within the integrated cylinder. The upper cylinder body consists of an upper left cylinder body, an upper T-shaped connecting cylinder body, and an upper right cylinder body, all fixed between the upper left and upper right cylinder bodies. The upper and lower cylinder bodies are detachably connected via bolted joints. The upper T-shaped connecting cylinder body and the lower T-shaped connecting cylinder body are each provided with shaft holes; similarly, the right upper cylinder body and the right lower cylinder body are also equipped with shaft holes. The main shaft sequentially passes through these three shaft holes. Three steam seals are fixed to the circumferential surfaces of the shaft holes, respectively located within the three shaft holes, and the steam seals are fitted with clearance into the shaft holes. The turbine sleeve rotor comprises a turbine impeller, a turbine oil seal ring, and a turbine shaft sleeve. The turbine oil seal ring and the turbine shaft sleeve are arranged in two sets, with the two sets of turbine oil seal rings and turbine shaft sleeves positioned symmetrically about the centerline. The turbine impeller includes turbine impeller blades and a turbine moving blade row. Both the turbine impeller blades and the turbine moving blade row are equipped with multiple blades. The turbine moving blade row is fixed to the outer end of the turbine impeller blades. The multiple turbine impeller blades are arranged in a stepped manner, with their heights increasing sequentially from left to right, and the specifications of the turbine moving blade row are identical. The generator sleeve rotor includes a generator core, a generator guard ring, and a generator slip ring, all of which are fitted over the circumferential surface of the main shaft with an interference fit.
Compared with the existing technology, the above-mentioned... Power generation steam turbine unit Has the following beneficial effects:
1. This design forms a turbine cylinder body between the upper-left cylinder block, the lower-left cylinder block, the upper T-shaped connecting cylinder block, and the lower T-shaped connecting cylinder block, and a generator cylinder body between the upper T-shaped connecting cylinder block, the upper-right cylinder block, and the lower-right cylinder block. This integration of the turbine cylinder body and the generator cylinder body simplifies the installation process, reduces the number of installation steps, and facilitates both installation and subsequent maintenance.
2. This design places the steam turbine sleeve rotor and the generator sleeve rotor around the circumference of the main shaft, thereby integrating the steam turbine sleeve rotor and the generator sleeve rotor with the main shaft for quick and convenient installation.
