The importance of training in the quality era of air compressors

Recently, when I was communicating with friends in the industry, I heard two cases. I think it is instructive for air compressor manufacturers or distributors who are "taking the quality" road, and they are worthy of our thoughts and learning. 　　1, compression<br></br> 　　 Adiabatic compression is a compression process in which gas heat is not significantly transferred or transferred during the compression process. The above process can become a reality in a fully insulated cylinder
