Common faults and solutions of compressors

A compressor is a machine that compresses gas to increase gas pressure or transport gas, and is widely used. In the mining industry, metallurgy industry, machinery manufacturing, civil engineering, petrochemical industry, refrigeration and gas separation engineering, and defense industry, compressors are one of the indispensable key equipment.
