How Vacuum Cleaners Absorbs Dirt
Article by Rams
The concept behind how vacuum cleaners work is not so complicated. Just as when you sip soda with a straw, this appliance revolve around the principle of suction mechanism. How suction works is based on the fundamental concept of pressure.
Sucking the soda up reduces pressure from the top of the straw and increases pressure at the bottom of the straw, which causes the soda to flow upward towards your mouth. This is just a simple example of a suction mechanism.
A vacuum cleaner operates in a similar manner as it picks up debris and dirt from your carpet. In this article, you will see what is inside this equipment and learn some basic principles in physics, which makes a this appliance work.
The conventional vacuum cleaner is very simple and is made up of six essential components, namely:
1.Intake port is the point where debris and dirt enter the vacuum cleaner.
2.Exhaust port pushes out the air that comes in from the intake port during suction.
3.Electric motor helps produce suction.
4.Fan is the part that starts and keeps the suction mechanism running.
5.Porous bag collects and filters the sucked air of dirt and debris that were collected through the intake port.
6.Housing stores all the components together in an arranged and orderly manner for the efficient functioning of the vacuum cleaner.
When electricity is supplied to the vacuum cleaner and is switched on, the electric motor runs and the fan, which is attached to it, resembles like an airplane propeller rotates.
As the fan blades begin to turn, they will push the air towards the exhaust port. When this process begins, the air pressure in front of the fan increases while the pressure behind it decreases. This decrease in pressure creates a suction or partial vacuum inside the vacuum cleaner.
Since air always moves from high-pressure area to low pressure area, the ambient air moves into the cleaner through the intake port because the pressure in the partial vacuum is much lower than on the outside.
When the blow mode of the vacuum cleaner is being used, the exhaust port sucks air and the fan rotates the other way.
As long as the fan is running and the intake port remains open, there is a continuous flow of air moving through the intake port and out through the exhaust port via the porous bag. Due to the force of air caused by suction, dirt and debris also get sucked into the vacuum cleaner.
The absorbed air mixed with dirt and debris pass through the porous bag, which filters out the air and retains the dirt and debris. The bag can be emptied and cleaned to remove the collected dirt and debris.
The suction mechanism of a vacuum cleaner can be weaker or stronger depending on the power of the electric motor which determines the speed of the fan, the air passageway through the bag which accumulates the debris and dirt, and the size of the intake port where air passes through.
