The novel separation plate support further comprises an upper adjusting screw, an upper lug, an upper screw, a lower lug, a lower screw and a lower adjusting screw, the upper lug is connected with the upper semi-separation plate trough the upper adjusting screw, the upper lug is connected with the upper semi-cylinder through the upper screw, the lower lug is connected with the lower semi-separation plate trough the lower adjusting screw, and the lower lug is connected with the lower semi-cylinder through the lower screw.

Description

technical field [0001] The invention relates to a novel diaphragm support, in particular to a novel diaphragm support for a low-parameter back pressure steam turbine, which belongs to the field of steam turbine equipment. Background technique [0002] A low-parameter back-pressure steam turbine refers to a back-pressure steam turbine with an inlet steam pressure between 0.7MPa and 1MPa and an exhaust steam pressure between 0.1MPa and 0.3MPa. In some areas of our country, intermittent heat supply is required. In order to improve thermal efficiency, all generating units have carried out heating transformation, and low-parameter steam turbines can use the four-extraction steam of turbogenerators with power levels above 600MW and 1000MW to meet the heating demand. On the basis of driving various pumps, fans, compressors and generators to do work or generate electricity, and at the same time replace the temperature and pressure reducer, realize the cascade utilization of energy, ...
