Vacuum Pumps: Why use them & what do they do?

A vacuum pump has the inlet hooked up to one or both valve covers, sometimes the valley pan. It SUCKS the air from the engine, thus reducing the air pressure build up created by blow due to combustion gases going past the piston rings into the pan. Vacuum pumps vary in the amount of air volume (CFM) they can suck so the potential VACUUM a pump .

Rotary Pumps - an overview | ScienceDirect Topics

A series of vanes in vane pumps is shown in Fig. 23.3. Vane pumps are commonly used on mobile hydraulic equipment. Fig. 23.3 shows an unbalanced vane pump; by use of an elliptical-shaped housing with a central rotor, each pair of vanes can have two inputs alternated by two outputs for each rotation. Rotary vane pumps are also used for vacuum pumps.

Succeed at Vacuum System TROUBLESHOOTING

lowest vacuum operating pressure for the pump would be: P1 = (2)(13.3) = 26.6 mm Hg Operating the vacuum pump's suction pressure below this level will result in cavitation of the wa-ter within the pump that ultimately can damage the pump's impeller (Figure 1).
