HOW DOES A VACUUM CLEANER WORK?
The shark rotator professional manual is an essential appliance that allows you to efficiently vacuum the dust present in a room. Everyone knows how to use it, but how many people actually know how it works?
LITTLE DESCRIPTION OF THE VACUUM
Before going into the technical details, let’s see what a vacuum cleaner is made of. The vacuum cleaner can be divided into several parts:
the brush or nozzle that serves as an air inlet
the hose and / or tube that carries air to the interior of the vacuum cleaner
the bag or tank that retains the dust
the engine filter which retains the microparticles to protect the engine
the motor which creates the air flow essential for the operation of the vacuum cleaner
the air outlet filter which retains the microparticles from the engine in order to preserve good air quality
the air outlet which expels the air from the vacuum cleaner
It is good to know that there are some differences between a bagged vacuum cleaner and a bagless vacuum cleaner, we will see it below.
BASIC PRINCIPLES ON THE OPERATION OF THE VACUUM
The operation of a vacuum cleaner is simple but is based on complex technical principles. In summary, we can say that the vacuum cleaner uses its brush or its nozzle to straighten the fibers which retain the dust while its motor creates a vacuum which sucks up dirt and dust. But let’s see in more detail how this machine works.
THE PHENOMENON OF DEPRESSION
By connecting the vacuum cleaner, the electric current feeds its motor. This activates a fan which generates a pressure drop behind it (that is to say at the back of the device) and which creates a continuous flow of air. This is why, as long as the engine is on, the vacuum cleaner sucks in relentlessly. The depression is expressed in kilo Pascal (kPa): the higher the value, the more powerful the vacuum cleaner. This air flow mainly sucks dust and small dirt.
THE FRICTION PHENOMENON
But, we had to find another way to vacuum the big dust and dirt. The friction phenomenon made this possible! By using a brush that rubs the floor back and forth, and in particular textile surfaces such as carpet, the dust particles come off the ground and are found in the air. The suction of the device can thus recover them.
AIR ROUTE IN THE VACUUM
With these principles in mind, we can easily understand the path taken by the air in the vacuum cleaner. However, since there are two types of vacuum cleaners (with or without bag), we explain this route for both models.
VACUUM CLEANER WITH BAG
The bagged vacuum cleaner is the oldest model of vacuum cleaner. Its operating principle has not changed since its creation, only its capacities and its power have evolved. The bag used contains micro-perforations which allow air to pass through while retaining large dust. Industrial vacuum cleaners have bags that hold large debris like pieces of wood, plants or soil.
The air flow is as follows:
The air enters through the squeegee or the brush and goes up into the hose then the tube to land in the bag.
The larger dust remains trapped in the bag while the air continues to flow to the engine filter.
The engine filter captures the remaining dust so as not to clog the engine. The air continues its way towards the engine and arrives at the air outlet filter.
The air outlet filter is the last step: it collects dust from the motor and thus lets clean air come out of the vacuum cleaner.
