Abstract

The invention discloses a lower pipeline reinforcing device and method for replacement of cylinders of a turbine. The lower pipeline reinforcing device comprises at least two transverse beams, at least two longitudinal beams and a clamping device, wherein the transverse beams and the longitudinal beams are crossed to define a channel for accommodating a pipeline, and the distance between the transverse beams which are oppositely arranged or the distance between the longitudinal beams which are oppositely arranged is equal to the outer diameter of the pipeline. The clamping device is fixed to the transverse beams or/and the longitudinal beams, is coaxial to the channel, and is used for applying annular clamping force to the pipeline. By means of the lower pipeline reinforcing device and method, the problems that when the high-medium-pressure cylinders of the turbine are replaced, after a lower pipeline is cut, during back-installation, precise assembly cannot be achieved, and the staggering rate is high can be solved, and the problem that reinforced groove steel is cut for the second time, and the working procedures are complicated can also be solved.

Description

technical field [0001] The invention belongs to the technical field of pipeline reinforcement, and in particular relates to a pipeline reinforcement device and a reinforcement method for replacing a cylinder block of a steam turbine. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] In recent years, with the rapid development of my country's economy, the demand for electricity is increasing. At present, 300MW units account for more than 30% of my country's total installed capacity. Many of the 300MW units in service were built in the early 1980s. These units have been put into operation for a long time, and generally have problems such as poor thermal performance and low re...
