See Xiao Bian following introduction, these skills must get√! How to buy a cost-effective vacuum pump? Vacuum pump selection guide: 1, you must check to determine the vacuum required for each process. 2, check the vacuum system vacuum limit. In general, 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 foreline pump. 3, check the process to determine the type of extraction and extraction of air extraction. 4, check to determine the time required to reach the required degree of vacuum, vacuum pipe flow resistance and leakage. Consider to achieve the requirements of the vacuum degree of vacuum in a certain process conditions required to maintain the vacuum pumping rate.
