What are the three parts of the vacuum system?
Vacuum engineering systems, whether utilized in industrial manufacturing, scientific research, or semiconductor fabrication, are fundamentally constructed from three essential operational subsystems. The first part is the vacuum chamber or vessel, which provides a structurally robust, hermetically sealed enclosure capable of withstanding external atmospheric pressure while housing the process or experiment. The second part is the pumping group, consisting of roughing pumps and high-vacuum pumps designed to evacuate gas molecules continuously from the chamber to achieve the desired low-pressure environment. The third part is the instrumentation and valving subsystem, which includes vacuum gauges, mass spectrometers, and isolation valves used to monitor, regulate, and control system pressure parameters accurately.
