With our baseline confirmed, we added the vacuum pump and re-ran the tests. The Star vacuum pump created 15 inches of vacuum in the crankcase and the power increased from 741 to 760 hp.

And yes, the 01 can also be used to charge other electronic gadgets such as smartphones or cameras. The whole thing measures 70 by 48 by 48 mm (2.8 by 1.9 by 1.9 in), is claimed to tip the scales ...

Compressors use a pressure switch to stop the motor when tank pressure reaches a preset limit–about 125 psi for many single-stage models. Most of the time, though, you don't need that much pressure.

If a CW pump trips, reverse flow, water hammer, backwards pump rotation, pump over speed, pipe over pressure, pipe vacuum pressure, cavitation, or a forced steam turbine shutdown can occur.

Master Power Brake's new specialized vacuum pump doesn't need a canister, however. This new pump has a built-in sensor that will measure the vacuum and deliver the necessary amount only when needed.

DARPA’s Chip-Scale Vacuum Micro Pumps (CSVMP) achieved an ultimate goal of a vacuum pressure of 10^-6 Torr (1 Torr is 1/760 of 1 atmosphere) for a tiny 1 mm3 compartment with the smallest, most ...
