Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of compressors, in particular to a compressor pipeline cleaning structure and a cleaning method. BACKGROUND

[0002] After a long time of use, the internal pipeline of the compressor can accumulate various impurities, such as dust, rust, oil stains, etc. Especially for those special-shaped pipes or compressors with curved pipelines, the cleaning work is particularly difficult.

[0003] The existing cleaning tools on the market are mostly cleaning balls made of rubber blocks or foam blocks with a certain elasticity in a spherical or cylindrical shape. When using, the cleaning ball is placed in the pipeline that needs to be cleaned, and then compressed gas is introduced into the pipeline to push the cleaning ball to move in the pipeline, thereby cleaning the inside of the pipeline.

[0004] In order to maintain good cleaning ability, the current cleaning ball needs to be set slightly larger than the diameter of the pipeline, so that the cleaning ball can be in full contact with the side wall of the pipeline and improve the cleaning efficiency. However, since compressed gas is used as the driving force, the cleaning ball has a large gap with the side wall of the pipeline under the action of the compressed gas, which reduces the force of the compressed gas on the cleaning ball, reduces the moving speed of the cleaning ball and the cleaning effect, and further reduces the cleaning efficiency of the cleaning ball on the special-shaped pipe or curved pipeline.
