Fire resistant oil pipeline sliding support for steam turbine

Abstract

The invention provides a fire resistant oil pipeline sliding support for a steam turbine. The fire resistant oil pipeline sliding support comprises a vertical support vertical column, wherein fixed bases with sliding rails are laid below the support vertical column, the bottom of the support vertical column is connected with a sliding base matched with the sliding rails of the fixed bases, the side face of the support vertical column is connected with a pipe clamp in parallel, a plurality of pipeline through holes are formed in the pipe clamp vertically side by side, and the pipeline through holes are parallel to the sliding rails. The fire resistant oil pipeline sliding support has the advantages that stress generated due to thermal expansion of equipment connected with a fire resistant oil pipeline can be fully released, pipeline bending deformation caused by thermal expansion is completely eliminated, vibration of the fire resistant oil pipeline is effectively avoided, looseness of a connector for connecting the tail end of the pipeline with a hydraulic servo-motor or a pipeline welded junction tension fracture is avoided, and safe and stable operation of a steam turbine generator unit is guaranteed.

Description

technical field [0001] The invention relates to a steam turbine anti-fuel pipeline sliding support. Background technique [0002] The steam turbine high-pressure fuel-resistant system is an important part of the steam turbine control system. It is widely used in today's large-scale steam turbine generators because of its advantages of strong flame resistance, good controllability, stable performance and high operating pressure. In recent years, although the pipeline layout of the fuel oil-resistant system has become more and more perfect, it has exposed the problem that the pipeline support cannot expand freely with the pipeline during operation, mainly because its root is designed to be connected to the fixed plate by welding, which makes the connection point impossible. Swipe freely. During the start-up process of the unit, with the thermal expansion of the anti-fuel pipeline connection equipment (high and medium pressure steam valves, high and medium pressure steam inlet...

Problems solved by technology

In recent years, although the pipeline layout of the fuel oil-resistant system has become more and more perfect, it has exposed the problem that the pipeline support cannot expand freely with the pipeline during operation, mainly because its root is designed to be connected to the fixed plate by welding, which makes the connection point impossible. free slide

During the start-up process of the unit, with the thermal expansion of the anti-fuel pipeline connection equipment (high and medium pressure steam valves, high and medium pressure steam inlet pipelines), the anti-fuel pipeline will also expand accordingly, but the pipeline will bend and deform due to the limitation of the bracket, and even cause The joint between the end of the pipeline and the oil motor is loose or the welding joint of the pipeline is cracked, causing oil leakage and causing shutdown accidents, directly threatening the safe and stable operation of the turbogenerator
