The role of the vacuum pump

The function of the vacuum pump is to remove gas molecules from the vacuum chamber, reduce the gas pressure in the vacuum chamber, and make it reach the required vacuum degree. Broadly speaking, there is a wide range from the atmosphere to very high vacuum, and so far no vacuum system has been able to cover this range. Therefore, in order to achieve the process indicators, work efficiency and equipment service life requirements of different products, different vacuum sections need to choose different vacuum system configurations. For optimal configuration, the following points should be considered when selecting a vacuum system:
The vacuum level required for each process must first be checked to determine the required vacuum level. Because each process has its own range of suitable vacuums, it must be carefully studied to determine.
The ultimate vacuum of the vacuum pump system is checked on the basis of determining the vacuum level required by the process, because the ultimate vacuum of the system determines the optimal working vacuum of the system. Generally speaking, the ultimate vacuum of the system is 20% lower than the working vacuum of the system and 50% lower than the ultimate vacuum of the backing pump.
Check to determine the type and amount of pumping required by the process. Because if the type of gas to be pumped reacts with the liquid inside the pump, the pump system will be contaminated. At the same time, consideration must be given to determining the appropriate exhaust time and the amount of gas generated during the pumping process.
