What is a pump? |
A mechanical device that pushes or move fluid or air from one place to another |
|
|
|
Centrifugal pump components? |
Back (Definition) |
|
|
|
What is an impeller? |
Circular disc is with curved vanes enclosed by second disc that imparts energy on water |
|
|
|
What’s the role of the volute? |
It slows water down and coverts from velocity energy to pressure energy, channels water |
|
|
|
What does a Multi-stage series pump do and benefits? |
Uses a series of impellers to increase the pressure of water in the pump Operates in high flow and high pressure |
|
|
|
Pump and primers when drafting? |
Primers are used when obtaining water from a static/open water source Rotary vane primers Piston primers |
|
|
|
Pump lifts in metres? |
3m - rated pump 4.5m - approx 20% loss 6m - approx 40% loss 7.5m - approx 66% loss 10m - Max lift |
|
|
|
Powering the pump there are two types of redirection devices? |
Transfer case - the pump and the rear wheels can not be operated at the same time, it is not connected to the transmission Power Take-Off(PTO) - attached directly to the transmission and usually applied to side or top of gearbox. PTO can be engaged and the vehicle can still be driven |
|
|
|
Impeller cooling Pumper vs Heavy Pumper? |
Pumper - has an automatic impeller cooler however this is only short term and a second deliver valve should be open to avoid heating up (run a bleed) Heavy pumper - recirc valve allows for small flow of water to cool pump |
|
|
|
What is Cavitation and what are the causes? |
The formation of water vapour bubbles in a steam of water. It directly affects the pumps performance and suction lift Causes- clogged strainer, suction hose that is too long or too small, a lift which is too high, water that is warm, attempting to pump more water than the hydrant can supply or by using a small supply hose |
|
|
|
Close vs open circuit relay pumping? |
Open is when you can see the water closed is when you can’t see the water |
|
