Vacuum Pumps: Types, Applications, and How They Work
A vacuum pump is defined as a device that reduces the pressure inside a chamber or container by removing gas molecules from it. The degree of vacuum achieved by a vacuum pump depends on several factors, such as the design of the pump, the type of gas being pumped, the volume of the chamber, the temperature of the gas, and the leakage rate of the system.
