Abstract

The invention relates to a supporting structure of a steam turbine, in particular to a double flexible supporting structure of a low-parameter saturated steam turbine. In order to solve the problems that in an existing steam turbine supporting structure, due to the fact that lubricating is not smooth, a sliding pin system is prone to getting stuck, and then safe running of the steam turbine is influenced, the double flexible supporting structure comprises a front steam cylinder, a front bearing box, a transverse key, a cat pad, a front bearing box supporting plate and a public base. The cat pad is arranged at the lower end of the front steam cylinder. The front bearing box is connected with the cat pad through the transverse key. The front bearing box supporting plate is arranged at the lower end of the transverse key. The double flexible supporting structure of the low-parameter saturated steam turbine further comprises a double flexible plate assembly. The double flexible plate assembly is fixedly mounted between the lower surface of the front bearing box supporting plate and the upper surface of the public base. The double flexible supporting structure is used for the technicalfield of the steam turbine, and by means of the double flexible supporting structure, safety, reliability and maintainability of the steam turbine are overall improved.

Description

technical field [0001] The invention relates to a steam turbine supporting structure, in particular to a low-parameter saturated steam turbine double-flexible supporting structure, which belongs to the technical field of steam turbines. Background technique [0002] The supporting structure of the steam turbine is mostly a sliding pin system. The operation of the sliding pin system requires lubricating oil on the sliding surface. Regular injection of lubricating oil increases the inspection and maintenance work of the steam turbine. Poor lubrication will also cause the sliding pin system to jam, causing The expansion of the steam turbine cannot be absorbed, thereby affecting the safe operation of the steam turbine. There are also some steam turbines that adopt a single-flexible support structure, and the force of the single-flexible plate will be weak, which will easily cause the eccentricity between the static and static parts of the steam turbine to increase, and then caus...
