Chapter 6: Aerodynamics: Homemade vacuum pump and

This pump can draw a vacuum like the first, but it can also inflate beach toys and air mattresses, or pump water. Whether pumping water or air, the stuff goes in one end and out the other, instead of travelling through a hollow piston like the first pump. To make

This chapter provides a brief overview of Valcon pumps and electronic or ion-sputter pumps. Valcon pump is a type of sputter-ion pump that makes use of both electric and magnetic fields to achieve the pumping action of a low pressure, electrical discharge. These electrical discharges are referred to as penning discharges.

Vacuum Pumps - an overview ScienceDirect Topics

The vacuum pump creates a vacuum in the tank and the oil moves directly through a hose or pipe to the tank from the skimmer or the source of the oil. The oil does not go through the pump, but moves directly from its source into the tank. Vacuum systems can handle debris, viscous oils, and the intake of air or water.
