The invention provides an axial exhausting exhaust cylinder of a bearing block supported in a landing manner. The axial exhausting exhaust cylinder comprises an exhaust cylinder shell fixed to an exhaust cylinder base. The bearing block used for supporting a rotor bearing is arranged in the exhaust cylinder shell. The bearing block is provided with a plurality of inclined supports extending to the outer portion of the exhaust cylinder shell. The ends, extending to the outer portion of the exhaust cylinder shell, of the inclined supports are fixed to the exhaust cylinder base. According to the axial exhausting exhaust cylinder, the bearing block is supported in the landing manner, the bearing block and exhausting area are isolated, the problem of a current base cylinder type axial exhausting exhaust cylinder is solved, and the stability of an axial exhaust turbine unit is improved. Meanwhile, the axial exhausting exhaust cylinder can be applied to an air cooling unit on the premise that the dynamic and static gap is not increased, and the efficiency of the air cooling unit is improved. The exhaust cylinder is the axial exhausting exhaust cylinder with the bearing block supported in the landing manner, meanwhile, the bearing block is completely isolated from the exhausting area, the exhaust cylinder is not affected by the change of exhausting parameters, and the axial exhausting exhaust cylinder can be suitable for air cooling and wet cooling at the same time.
Description
technical field [0001] The invention relates to an axial steam exhaust cylinder supported on the ground by a bearing seat. Background technique [0002] The steam turbine is one of the key power equipment in the construction of a power station. It is an energy conversion device that converts thermal energy into mechanical energy and then into electrical energy. The high-temperature and high-pressure steam generated by the boiler passes through the steam turbine to convert thermal energy and pressure potential energy into the mechanical energy of the steam turbine. , drives the steam turbine rotor output shaft to do work, and the mechanical energy is transmitted to the generator through the steam turbine shaft, thereby converting the mechanical energy into electrical energy. Therefore, the steam turbine is often called the "source of light" as the source of power. [0003] After the boiler is heated to the design parameters, the steam is led to the steam inlet area of the s...
