2. Pressure switch - Wikipedia

   en.wikipedia.org/wiki/Pressure_switch

   Murphy oil pressure gauges with switches that activate on low pressure. A pressure switch is a form of switch that operates an electrical contact when a certain set fluid pressure has been reached on its input. The switch may be designed to make contact either on pressure rise or on pressure fall. Pressure switches are widely used in industry ...

3. Oil pressure - Wikipedia

   en.wikipedia.org/wiki/Oil_pressure

   Murphy oil pressure gauges with switches that activate on low pressure. Oil pressure is an important factor in the longevity of most internal combustion engines. [1] With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big end bearings ...

4. Generac - Wikipedia

   en.wikipedia.org/wiki/Generac

   Generac continued to supply some transfer switches to Caterpillar until 2002, when Caterpillar changed suppliers. In 1998, Generac sold its portable products division to the Beacon group, a private equity firm, who later sold it to Briggs & Stratton Corporation. Upon expiration of a non-compete agreement related to the sale in 2007, Generac re ...

5. Oil pump (internal combustion engine) - Wikipedia

   en.wikipedia.org/wiki/Oil_pump_(internal...

   Indications of low oil pressure may be that the warning light is on, a low pressure reading on the gauge, or clattering/clinking noises from the engine. Low oil pressure is a problem that must be addressed immediately to prevent serious damage. The leading cause of low oil pressure in an engine is wear on the engine's vital parts.

6. Pumpjack - Wikipedia

   en.wikipedia.org/wiki/Pumpjack

   A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1] It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface. The arrangement is often used for onshore wells. Pumpjacks are common in oil-rich areas.

7. Recloser - Wikipedia

   en.wikipedia.org/wiki/Recloser

   Autoreclosers are made in single-phase [6] and three-phase versions, using oil, vacuum, or sulfur hexafluoride (SF 6) interrupters. Controls for the reclosers range from the original electromechanical systems to digital electronics with metering and SCADA functions. The ratings of reclosers run from 2.4–38 kV for load currents from 10–1200 ...
