AI Technical Summary

Technical Problem

The existing pipeline cleaning method based on airbag expansion technology has caused local stress concentration when the pipe bent part is cleaned, which in turn causes the problem of airbag rupture.

Method used

The pressure control module is adopted to dynamically adjust the gas pressure inside the airbag based on the preset pressure gradient control strategy, and to achieve uniform pressure distribution, and to physically clean the inner wall of the pipe through the continuous expansion and contraction of the airbag module.

Benefits of technology

It effectively avoids the problem of local stress concentration, reduces the risk of airbag rupture, improves the operating stability and cleaning effect of the cleaning system in the bent part, significantly improves the cleaning efficiency, and extends the service life of the airbag.

Abstract

The invention discloses a pipeline inner wall cleaning system based on an air bag expansion technology, which comprises a pressure control module used for dynamically adjusting the air pressure in an air bag and realizing uniform pressure distribution based on a preset pressure gradient control strategy, and an air bag module used for being inserted into a pipeline to be cleaned, the air bag assembly is used for carrying out physical friction cleaning on the inner wall of the pipeline through continuous expansion and contraction after the air bag gradually expands to make contact with the inner wall of the pipeline, the air supply module is used for providing controllable air pressure for the air bag assembly, and the exhaust module is used for exhausting air in the air bag assembly after cleaning is completed; according to the pipeline inner wall cleaning system based on the air bag expansion technology, the problem that in the prior art, due to the fact that pressure in an air bag is not evenly distributed, local stress concentration is generated when a bent part of a pipeline is cleaned, and then the air bag is broken is solved.
