Disclosed are a vacuum pump air exhaust process simulating and testing method and a testing system. By means of a built simulating vacuum chamber, common elements in various dry-type vacuum pump application environments such as gas, liquid, electricity, magnetism, heat, dust, and corrosion are integrated, various sensors are used to perform feedback on a signal simultaneously having temperature, humidity, gas ingredient, real-time image, pressure, traffic and noise, and multiple control systems are used to perform monitoring, so as to check and improve dry-type vacuum pump air exhaust process adaptation situations. The testing system uses strict contaminant collecting and shuttling treatment, has a danger warning and automatic protecting function system, is characterized by being secure, intelligent, and green and environment-friendly, has good repeatability, and may simulate vacuum pump air exhaust process environments such as cleaning, mildly-polluted, intermediately-polluted and seriously-polluted vacuum environments comprising transfer, physical vapor deposition, chemical vapor deposition, etching, photolithography, chemical engineering, and pharmacy.
