Vacuum pump - Wikipedia

A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum.The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity....<<more>>

What Causes a Gas Cap Vacuum? | Hunker

When vacuum levels drop, the solenoid closes the valves to increase pressure. If the solenoid becomes damaged and stays stuck in the "on" position, the fuel system will build up enough suction to create a strong vacuum at the gas cap....<<more>>

Chapter 3: Review of Basic Vacuum Calculations

Vacuum technology is based upon the creation of an environment in which a process (thin film deposition, electron beam welding, etc.) can be carried out. This normally implies that one remove air from a system to some acceptable sub atmospheric pressure by the use of some type of vacuum pumping equipment....<<more>>

Gas Ballasting of Vacuum Pumps (Part 2) | 2017-01-10

Gas ballast is the introduction of a non-condensable gas (e.g., air or nitrogen) into a rotary-vane pump, during the compression stage to intentionally impact the efficiency of the pump thereby heating the oil inside and helping to drive out water and other condensed liquids present in the pump oil....<<more>>

How to Match Pumping Speed to Gas Load - Rooks Vac

HOW TO MATCH PUMPING SPEED TO GAS LOAD Pumping speed is one of the triumvirate of quantities that make up the fundamental relationship that governs the behavior of all vacuum systems. This relationship, written as Q (gas load) = S (pumping speed) x P (pressure), should be constantly in the forefront of the mind of every vacuum technologist....<<more>>
