Vacuum Chamber
Key words:
There are many kinds of vacuum pumps that have been developed, and their pumping speed ranges from a few tenths of a liter per second to hundreds of thousands and millions of liters per second. With the vacuum technology in the field of production and scientific research on its application pressure range more and more wide requirements, most need to be composed of several vacuum pump vacuum pumping system after common pumping to meet the requirements of production and scientific research process, because the vacuum application department involved in the range of working pressure is very wide, Therefore, any type of vacuum pump can not be fully applicable to all working pressure ranges
