What Are The Principles For Selecting A Vacuum Pump?
Dec 06, 2022| (1) Structure of vacuum pump: for pumping corrosive gas, the vacuum pump must be made of corrosion-resistant materials or lining corrosion-resistant materials. The vacuum pump with lubricating oil shall not be selected for pumping the gas acting on the oil.
(2) Meet the process requirements: if the amount of non condensable gas at the top of the vacuum tower is large, the steam jet vacuum pump must be selected, because it has the characteristics of high vacuum, simple structure, easy operation, etc., which creates a very high vacuum in the vacuum tower, which is conducive to fractionation under reduced pressure, and ensures the product quality.
(3) Sufficient air extraction rate: the gas to be pumped can be pumped out within the allowable time to ensure the normal production.
(4) Working time: continuous working time can ensure the basic requirements of a process cycle, and production cannot be affected due to short continuous working time.
