What is cavitasion in pump technology?What is small pressure drop in Distilation column? Help me --------fast?

Answer 1

In science you must have studied that the boiling point of water drops with a reduction of atmospheric pressure.
At a pressure of zero atm(atmosphere), which is vaccum, water will boil at room temperature.
This boiling is actually the release of the air mixed in the water.
When a pump has a suction more than 1 atm. which is roughly 27.7 feet, the vaccum created by the pump causes the air in the water to be released as mentioned above.
This release of air is known as cavitation.
Cavitation also occurs when the propellor of a boat or ship moves too fast though the water creating a vaccum on the blade surfaces.
That is why you see a 'wake' behind a boat or ship

Answer 2

Cavitation is what happens if your pump is running dry. (not pumping your product). This will cause the pump vanes to wear, and you wont generate the internal vacuum to pump with. A small pressure drop in your distillation column could be cause by a system leak somewhere, or maybe you have some foaming going on. Good luck.

Answer 3

When the pressure off the water drops it will form vapor bells. The moment the bells are propel d in to normal pressure they will implode cosing damage to the vanes if to near. You will find more information here :http://en.wikipedia.org/wiki/Cavitation

if it is an above ground or jet pump your foot valve is bad or you have hole in line somewhere in the small line as if there was one in the big line (suction line) pump would not work...if it is a submersible pump then your pump does not have a check valve or it is bad there needs to be a check valve at the top of pump or between pump and tank at top of welll...
