Vacuum systems work by creating a pressure difference, drawing air in. There are five types of household vacuum cleaners, each with different features, but all work on the same principles. Vacuum systems are used in households, manufacturing, and robotics, and have an impact on space exploration.
All vacuum systems work by creating a difference in air pressure. The initial suction is created by reducing the pressure inside the vacuum tube, either with the use of a pump or motor. Atmospheric pressure draws air into the vacuum system to bring pressure levels back to normal.
To understand how vacuum systems work, follow the steps below. Stand upright and place your palms on your stomach. Feel your stomach move as you breathe in and out. Exhale as much air as you can and see what happens next. As soon as you stop expelling air, your lungs will force you to inhale, exactly how vacuum systems work. To equalize the air pressure in the lungs, air is drawn in without any effort on your part.
Vacuum systems are used in households and manufacturing. There are five different types of household vacuum cleaners available. Each of these models offers slightly different features, but all vacuum systems work on the same basic principles.
Upright vacuum cleaners use a brush roll or beater bar to agitate the dirt and then collect it through the use of fans. There are two types of fan designs: dirty fan or clean fan. The dirty fan design places the fan near the suction opening and the clean fan design places the fan behind the dirt collection bag.
A canister vacuum cleaner has a motorized drum housed separately from the vacuum head. Wet vacuum cleaners use the same principles as canister vacuum cleaners, but are designed for use with wet and dry materials. Pneumatic vacuum cleaners are connected to compressed air and are common in industrial plants.
Central or built-in vacuum cleaners have a powerful motor that is permanently installed in the building. Pipelines and vacuum inlets are located throughout the facility. The user only needs to carry the hose and collection head to vacuum the space. The horsepower delivered by this type of system is typically higher than other vacuum types, as significant pressure must be built up to create the appropriate level of suction in a multi-outlet system.
Vacuum systems are very common in robotics and manufacturing plants. Research and development work is underway to promote better measurement and analysis of vacuum and pumping. These mechanical functions have an impact on the future development of vacuum systems and are in high demand for use with space exploration projects.
