How Vacuum Cleaners Work – they suck
Even though it may appear to be a very complicated machine, the conventional vacuum cleaners are actually made up of six essential components: intake port, exhaust port, electric motor, fan, porous bag, and a housing that stores all of the other components.
When you plug vacuum cleaners into the outlet and turn it on, the following happens:
1. First of all, the electric current will operate the motor, which is attached to the fan, which resembles an airplane propeller.
2. As the blades begin to turn, they will force the air upwards, towards the exhaust port.
3. When the air particles are driven forwards, the density of the particles will increase in front of the fan and therefore decrease behind it.
The pressure drop that occurs behind the fan is similar to the pressure drop when you take a drink through a straw. The pressure level in the area that is behind the fan will drop below the pressure level that is outside of vacuum cleaners.
This will create a suction inside of vacuum cleaners. The ambient air will push itself into vacuum cleaners through the intake port because the air pressure that is inside of vacuum cleaners are much lower than the pressure on the outside.
Picking the dirt up
The stream of air that vacuum cleaners generate is just like a stream of water. The air particles that move will rub against any loose dust or debris and if it is light enough, the friction will carry the material around the inside of vacuum cleaners.
As the dirt continues on to the exhaust port, it will pass through vacuum cleaners bag. They tiny holes in vacuum cleaners bag are large enough to let the air pass through, although too small for the dust particles to fit through. Therefore, when the air current gets into the bag, the dirt and debris will be collected there.
You can stick the bag anywhere along the path between the intake tube and the exhaust port, just as long as the air current passes through.
Suction
The power of a vacuum cleaners suction will depend on several factors. The suction can be stronger
or weaker depending on:
1. Fan power – In order to generate a strong suction, the motor needs to turn at a good speed.
2. Air passageway – When a lot of debris builds up in the bag, the air will face a greater level of resistance on the way out. Each particle of air will move slowly due to the increase in drag. This is the reason why a vacuum cleaners work much better once you’ve replaced the bag than when you have been using it for a while.
3. Size of the intake port – With the speed of the vacuum fan being constant, the amount of air that passes through vacuum cleaners per second is also constant.
