System and method for automatically adding anti-vibration strips to gas condenser

Abstract

The invention provides a system and method for automatically adding anti-vibration strips to a gas condenser. The system comprises an adding body, a guide rail assembly, a support frame assembly, a control unit and a shearing unit, wherein the adding body is slidably arranged on the guide rail assembly and used for adding the anti-vibration strips among to-be-inserted tube bundles of the gas condenser; the guide rail assembly is used for adjusting the adding body in the height direction; the supporting frame assembly is used for fixing the guide rail assembly and the gas condenser. and the control unit is used for controlling the adding body to add the anti-vibration strips and controlling the shearing unit to shear off the redundant anti-vibration strips. According to the invention, the purpose of automatic adding for the anti-vibration strips in an existing unreachable area is achieved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a system and method for automatically installing anti-vibration strips in a condenser. Background technique [0002] A condenser is a heat exchanger that condenses turbine exhaust steam into water. It is generally horizontal, up to 20m long, with as many as tens of thousands of titanium tubes installed along the length direction. The titanium tubes are arranged with support plates every 700mm. The support plates cooperate with the titanium tubes on both sides to have a certain degree of freedom of movement. . During the operation of the condenser, especially when the working conditions change suddenly, the long-term vibration or excitation will intensify the friction between the titanium tubes, resulting in the wear and tear of the titanium tubes and even leakage, which will lead to unplanned shutdown. Practice has proved that adding plastic anti-vibration strips between ti...

Problems solved by technology

During the operation of the condenser, especially when the working conditions change suddenly, the long-term vibration or excitation will intensify the friction between the titanium tubes, causing wear and even leakage of the titanium tubes, which will lead to unplanned shutdown

Practice has proved that adding plastic anti-vibration strips between titanium tubes is an effective measure to reduce the vibration of titanium tubes. Due to the structural limitations of the tube bundle arrangement and the visible distance between the tubes is only 2.2mm, the thickness of the anti-vibration strips is about 2.5mm. Large resistance; in the height direction, manual installation of anti-vibration strips can be implemented between about 12 rows of pipes from the top down, and the rest of the area is inaccessible to personnel.
