doi:10.13385/j.cnki.vacuum.2022.05.08

Abstract

Abstract: Compared with the vapor jet vacuum pump system served at present,the high differential pressure Roots pump combination pumping system is being widely used for large vacuum distillation unit because it has the characteristics of quick start and obvious energy saving effect.In this paper,one kind of combination pumping system consisted of high differential pressure roots pump used in a large vacuum distillation deep cut unit is introduced,and the structure,control principle,performance parameters and solutions to some key technical problems of the system are described in detail.

Key words: high differential pressure Roots vacuum pump, vacuum distillation, pumping system, sealed construction, corrosion

CLC Number:

TB752+.26
