Abstract

The invention discloses a steam turbine energy saving improvement structure and an improvement method of the steam turbine energy saving improvement structure. The steam turbine energy saving improvement structure comprises a steam cylinder, a steam chamber, a regulating valve, a nozzle set, a single-row regulating-stage impeller, a pressure-stage impeller, multi-stage separating plates, separating plate steam seals, separating plate grooves, a front base frame, a rear base frame, a bearing, a jigger, a rotor assembly, a bearing box, front steam seals, rear steam seals and a coupling. The steam turbine energy saving improvement structure and the improvement method of the steam turbine energy saving improvement structure have the advantages that the investment is low, the construction period is short, operation is easy, the rotating speed of an existing steam turbine is unchanged, the efficiency is high, the efficiency, the safety and the stability of an improved set in the practical running process meet the predetermined requirements, and the effect is quite good.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a steam turbine energy-saving transformation structure and a transformation method thereof. Background technique [0002] A steam turbine is a rotary power machine that converts the energy of steam into mechanical work, and is widely used in production and life. It is mainly used as a prime mover for power generation, and can also directly drive various pumps, fans, compressors and ship propellers. It is also possible to use the exhaust steam or intermediate steam extraction of the steam turbine to meet the heating needs of production and life. [0003] Most of the steam turbines below 60MW currently operating in enterprises are steam turbines produced with imported technology in the 1940s. With the development of the times, the efficiency of these steam turbines is far from meeting the needs of production. Many enterprises replace these steam turbines with domestically imported or Imp...
