Vacuum Pump
A Closer Look At The Vacuum Pump
A vacuum pump is a device that removes gas molecules from a sealed column in order to leave behind a partial vacuum. The vacuum pump was invented by Otto von Guericke in 1650.
The basic information needed to know to understand how a vacuum pump work is how the low pressure regions power the vacuum system. Molecules in the air do not like the areas of low pressure and rush to immediately escape to higher pressure areas. Tornadoes are excellent examples of natural vacuums.
A vacuum pump can be categorised into two types:
- Transfer pumps are also called kinetic pumps since they impart the momentum to the gas which is being pushed in such a way that the gas is transferred continuously from the inlet of the pump to the outlet.
- The trapping or capture pumps are usually located in the container being evacuated. The trapping pumps remove gas molecules by sorption or condensation on its internal surfaces.
There are many different types of vacuum pumps and there are also many different uses for a vacuum pump in house hold and commercial vacuum cleaners, for vacuum sealing food, or vacuum packaging other objects you wish to save from the elements.
Vacuum pumps are also used in many industrial and scientific processes, including:
- Milking machines
- Trash compactor
- Freeze drying
- Electron microscopy
- Driving some of the flight instruments in most aircraft
- Medical processes that require suction
- Vacuum coating for decoration, for durability, for energy saving
- As the main source of vacuum in a dairy shed plant
- Medical applications such as radiotherapy, radiosurgery and radiopharmacy
Vacuum power is used not only to create airtight storage space like training facilities or experimentation, but a vacuum pump is also used to remove fat and abnormalities from the inner human body, pimples and blackheads from the skin, and even to combat erectile dysfunction problems.
