  2. Pressure tank - Wikipedia

    en.wikipedia.org/wiki/Pressure_tank

    The diaphragm or bladder may itself exert a pressure on the water, but it is usually small and will be neglected in the following discussion. Case 1 is an empty tank at the charging pressure P c (gauge). The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V. Referring ...

  3. 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.

  4. Bladder tank - Wikipedia

    en.wikipedia.org/wiki/Bladder_Tank

    Bladder tanks have many capacities ranging from 500 liter up to 1 million liters. Liquid stored in a flexible bladder tank does not evaporate and any odor it may produce is completely sealed within the tank. Because the bladder tank works in a vacuum, contaminants cannot enter, what you put in is what you get out. [5]

  5. Hydraulic accumulator - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_accumulator

    The water is pumped from the harbour into a header tank and then fed by gravity to the pumps. The working pressure is 750 psi (5.2 MPa, or 52 bar) which was used to power the cranes, bridges and locks of Bristol Harbour. [citation needed] The original operating mechanism of Tower Bridge, London, also used this type of accumulator.

  6. Constant Pressure System - Wikipedia

    en.wikipedia.org/wiki/Constant_Pressure_System

    Due to the nature of the bladder, the stream produced is fairly constant, and has almost the same range and power throughout the entire shot, most streams dropping only one foot in range towards the end of a continuous shot, unlike most air pressure based water guns which exhibit a constant loss of pressure while the trigger is pulled. [2]

  7. Blowout preventer - Wikipedia

    en.wikipedia.org/wiki/Blowout_preventer

    In drilling a typical high-pressure well, drill strings are routed through a blowout preventer stack toward the reservoir of oil and gas. As the well is drilled, drilling fluid , "mud", is fed through the drill string down to the drill bit, "blade", and returns up the wellbore in the ring-shaped void, annulus , between the outside of the drill ...
