Description

Technical Field

[0002] Based on the consideration of ensuring the safety of the production and operation of water supply equipment, after the dosing equipment or the online water quality monitoring equipment has been running for a period of time, the relevant pipelines need to be periodically maintained, unblocked and cleaned. However, due to the small diameter of the equipment pipeline and the slow flow rate, it is easy to form deposits in the pipeline, and the sediments are unevenly distributed inside the pipeline, especially in the elbows. Severe corrosion of the pipeline will reduce the strength of the pipe wall, and it is easy to cause accidents such as pipe bursts. In the past, when cleaning the pipeline, there were great cleaning difficulties, low cleaning efficiency, poor cleaning effect, and sometimes even the need to replace the pipeline. In order to solve the above problems, while ensuring the flushing quality and work efficiency, extending the service life of the pipeline, and reducing the accident rate, the utility model proposes a steerable pipeline inner wall cleaning device.
