How to solve the daily problems of compressed air pipeline

According to the debugging experience of the new automobile painting production line, the compressed air system, the source of impurities in the compressed air pipeline, the cleaning method of the compressed air pipeline, the cleaning standard, and the matters needing attention in the cleaning process were described.

The main points of the compressed air system specification and the basic requirements of pipeline design and installation are introduced. A design example of a 49,000DWT bulk carrier's compressed air system is presented. Combined with the typical technical problems in the design of previous real ships, the paper gives a specific solution through theoretical analysis and experience summary

In this paper, the gas leakage in the brake pipeline of commercial vehicle chassis is studied. The conical seal joint with precoated adhesive is developed, which can effectively improve the sealing property of the pipe joint of the air braking system of commercial vehicle on the basis of a small increase in cost.

The water content of compressed air in winter is obviously abnormal, which leads to the phenomenon of pipeline freezing. The reason is analyzed according to the actual situation on the site, the result is verified, effective measures are taken to eliminate the intractable disease, which ensures the stable production of the power plant, and has certain practical guiding significance for the safe operation of compressed air system in the cold region of north China in winter.

By analyzing the principle and formula of gas flowmeter in common use, the influencing factors of measuring accuracy are given. The flowmeter selection of compressed air pressure reducing valve pipeline of a certain diesel engine is studied by using the flowmeter selection flowmeter flowmeter flowmeter.
