A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia and South Africa ), [ 2 ] [ 3 ] petrol pumps (in Commonwealth countries), or gas pumps (in North America ).
It is similar to that of a piston pump, but the high-pressure seal is stationary while the smooth cylindrical plunger slides through the seal. Plunger-type pumps are often mounted on the side of the injection pump and driven by the camshaft. [4] These pumps usually run at a fuel pressure of 3,600–26,100 psi (250–1,800 bar). [3]
The flow rate is an important parameter for a pump. The flow rate in a peristaltic pump is determined by many factors, such as: Tube inner diameter – higher flow rate with larger inner diameter. Pump-head outer diameter – higher flow rate with larger outer diameter. Pump-head rotational speed – higher flow rate with higher speed.
From sitting in your vehicle while your gas pumps to using inappropriate containers for spare gas, here are 9 things you should never do while pumping gas.
The blanket gas supply valve opens to maintain the pressure. As the tank fills with liquid the pressure rises and a vent gas valve open to vent gas to atmosphere or a vent system. [11] Rupture (bursting) discs (PSE) and pressure relief or pressure safety valves (PSV) are important pressure control devices. [3]
A gas-lift valve is a device installed on (or in) a gas-lift mandrel, which in turn is put on the production tubing of a gas-lift well. Tubing and casing pressures cause the valve to open and close, thus allowing gas to be injected into the fluid in the tubing to cause the fluid to rise to the surface. In the lexicon of the industry, gas-lift ...
If the pump casing becomes filled with vapors or gases, the pump impeller becomes gas-bound and incapable of pumping. [10] To ensure that a centrifugal pump remains primed and does not become gas-bound, most centrifugal pumps are located below the level of the source from which the pump is to take its suction.
