About the cleaning principle of compressed air pipeline

Compressed air pipeline, air compression, the temperature rises sharply, the air compressor must be equipped with an effective cooling system. Large air compressor cooling water system, water protection device must be sensitive and reliable. In case of interruption of water supply in operation, it is strictly prohibited to force water supply, and parking is required. Large air compressor should be set according to the characteristics of the equipment surge, vibration, oil pressure, water supply, shaft displacement and bearing temperature alarm interlocking device. Air drop test should be done before starting. In the process of high-speed air flow, rust and mechanical impurities may become hot fire, therefore, the position and height of the air inlet during the operation of the compressor should meet the safety requirements to prevent foreign matters from entering.

Cleaning principle: with compressed air as the power source, the cleaning gun is used to shoot a cleaning cotton ball into the pipe to be cleaned: the cleaning cotton ball, as a special consumable material of 10% polymer compound, moves along the pipe at high speed, and the inner wall of the pipe is fully and forcefully rubbed to achieve a new physical cleaning process method of cleaning the pipe.

While cleaning the pipe, it can also test whether the compressed air pipe is clean. Cooling water system failure. Air compressor cooling water, water supply shortage or high temperature cooling effect is not good, ultra high temperature in the compressor, lead to thermal cracking of lubricating oil, the air compressor bearings, cylinder, valve, compressed air pipeline, cooler, separator, and the place such as buffer tank formed coke, coke is a kind of combustible materials, under the high temperature overheating, mechanical impact, air impact can result in coke combustion, carbon oxide (such as CO, etc.), when the concentration reached the explosion limit, combustion and explosion happens.

In order to avoid affecting the operation of the whole station or other air compressor units during maintenance and to prevent the backflow of compressed air reliably during maintenance, a cut-off valve must be installed between the unit and the gas storage tank. Pressure, flow meter installation position and surface size should be able to enable the operator to see the indicated pressure, the pressure class scale range should make the working pressure in the dial scale 1/2 ~ 2/3 position. Due to environmental pollution, the air still contains sulfur dioxide, nitrogen oxides, carbon monoxide and other toxic gases. Dry air has a molecular weight of 28.96 and a density of 1.293g/m3 at 0 ° c and 760mmHg column.

Air after mechanical compression becomes compressed air, used to produce compressed air equipment is usually called air compressor, transport compressed air into compressed air pipe or air compressor pipe. Human beings have long known how to use compressed air, now compressed air is an indispensable power in human production and life. With the development of modern industry, the requirement of compressed air quality is higher and higher.
