Combined spring support device

Abstract

A combined spring support device comprises two spring supports, a vertical pipe bending head support, an upper rigid body and a lower rigid body. The lower rigid body comprises a lower base plate and two lower vertical plates vertically arranged on the lower base plate, the two spring supports are symmetrically distributed on two sides of the lower rigid body, the spring supports are also arranged on the lower base plate, the upper rigid body comprises an upper supporting plate and an upper vertical plate arranged on the upper supporting plate, two ends of the upper supporting plate is pressed on a loading board of the spring supports, upper friction pairs are arranged on a contacting surface of the loading board and the upper supporting plate, and the upper vertical plate stretches into a gap between` the two lower vertical plates in the lower rigid body. The combined spring support device is novel in structure, not only meets the requirement of a vertical thermal displacement support of an inlet and an outlet pipe of a turbo machine, but also solves the problem of axial thermal displacement of horizontal pipes in a very low friction coefficient, thereby greatly reducing the horizontal friction force undertaken by the turbo machine, and simultaneously eliminating the vibration produced during tanscritical speeds and ensuring stable and reliable running of the turbo machine.

Description

technical field [0001] The invention relates to a TRT combined spring support used in the iron and steel industry, in particular to a combined spring support device used in a TRT or BPRT energy-saving power generation device in a steel plant. Background technique [0002] TRT——(Blast Furnace Top Gas Recovery Turbine Unit, hereinafter referred to as TRT) blast furnace gas residual pressure turbine power generation device is a by-product of blast furnace smelting——the pressure energy and heat energy of blast furnace top gas, so that the gas passes through the A secondary energy recovery device that expands the flat machine to convert it into mechanical energy to drive a generator or other devices to generate electricity. The device not only recovers the energy released by the pressure reducing valve group, but also purifies the gas, reduces noise, stabilizes the furnace top pressure, improves the production conditions of the blast furnace, does not produce any pollution, and c...

AI Technical Summary

Problems solved by technology

The pulsation of pressure and the unbalanced rotation caused by the manufacturing error and installation error of the blade and shaft make the turbine casing and surrounding pipelines very prone to vibration, especially when the critical speed is exceeded, the system may generate low frequencies that the turbine cannot bear vibration

Seriously affect the service life of expensive turbines and other equipment, and even fail to run normally and continuously to generate electricity
