Design and Modeling of Vacuum Pumping Systems for Laboratory Scale Applications

Addala, Sandeep (2015) Design and Modeling of Vacuum Pumping Systems for Laboratory Scale Applications. MTech thesis.



Vacuum is a condition where the pressures are below atmosphere. Based on the pressures vacuum can be classified into low, medium, high and ultra high ranges. Vacuum finds its applications in many areas including industry, space research, food processing. One should have knowledge on the generation of vacuum to understand its effects. This project mainly focuses on the experimental setup of the vacuum pumps. The study, design, construction and installation of vacuum pumping systems viz. Vacuum chamber, Rotary pump, Roots pump was done. The working of rotary and roots pumps was studied and a list proper and necessary components and accessories was prepared. The methods to calculate the pumping speed of a pump at a pressure range were studied namely constant volume and constant pressure methods. The experiments were carried out and observations are plotted in a graph. The concepts of leak detection were also studied. Finally, the project helps in establishment of vacuum technology laboratory at NIT Rourkela, giving a practical approach to the students dealing with the Vacuum Technology to understand the vacuum process and research can be continued
