Pump Course |
| |
A pump is a device used to move gases, liquids or
slurries. A pump moves liquids or gases from lower
pressure to higher pressure, and overcomes this
difference in pressure by adding energy to the
system (such as a water system). A gas pump is
generally called a compressor, except in very low
pressure-rise applications, such as in heating,
ventilating, and air-conditioning, where the
operative equipment consists of fans or blowers.

Course
1- Positive displacement pumps |
|
|
A positive displacement pump causes a liquid or
gas to move by trapping a fixed amount of fluid
and then forcing (displacing) that trapped volume
into the discharge pipe. The periodic fluid
displacement results in a direct increase in
pressure. A positive displacement pump can be
further classified as either
* a rotary-type (for example the rotary vane),
* lobe pump similar to oil pumps used in car
engines, or
* the Wendelkolben pump or the helical twisted
Roots pump.

Course 2-
Pumps as public water supplies |
|
|
One sort of pump
once common worldwide was a hand-powered water
pump over a water well where people could work
it to extract water, before most houses had
individual water supplies.
From this came the expression "parish pump" for
"the sort of matter chattered about by people
when they meet when they go to get water",
"matter of only local interest".
