How A Vacuum Cleaner Works?

Quite classic is a vacuum cleaner a device that sucks the dust from the floor and furniture and collects in a dust bag. He owes us not only the ubiquitous spread of decorative and foot-warm carpets but also the possibility to clean fixed laid carpets!

This may sound banal, but it is quite revolutionary – like revolutionary, can only understand people who have someday brushed off a carpet on his hands and knees with a hand brush or dragged him four stairs down on the carpet rod in the courtyard to him afterwards knock with a carpet beater.

In short, the Best Buy Vacuum Cleaners is an incredibly labor-saving device that collects the dust in a bag. Lately there are also bag less vacuum cleaners, but we let them out here before.

Let’s take a look at the individual parts that are found in every bag vacuum cleaner:

Vacuum Cleaner Parts

Case back

The case back corresponds to the chassis of a car, so it is, so to speak, the chassis of the vacuum cleaner, the case back is the supporting part to which the motor and all other parts of the vacuum cleaner are attached.


This lid can be opened, because there are dust bags and possibly also filters that should be changed regularly.

Rear Cover

This part of the housing cover contains all the controls: the on / off switch and, if necessary, a regulator for adjusting the suction strength and a button for the automatic cable. The rear cover hides the engine and is only opened by the technician if repair is necessary.

Bag holder

In this bracket the dust bag is trapped. Here you can also tell if you have bought the right bag – so for the purchase of the best always note the bag number, In this mostly made of paper or non-woven bag, the dust collects. In Germany, there are over 1,200 (!) Different bag types – and of course, not every bag fits in every vacuum cleaner.

Power Cable

For the vacuum cleaner motor to run, the plug at the end of the power cord must be plugged into the socket. And so that you do not constantly have to drag the long cable behind you, there is a practical automatic retractor inside the vacuum cleaner.

How Does The Dust Get Into The Bag?

The dust is an unruly fellow. He likes to lazily lazy everywhere, but he likes to whirl around in attacks with cleaning cloth + broom and lie down somewhere else. So how do you get it in the bag?

Suction From Carpet

The dust is sucked in through the suction opening at the end of the suction hose – the so-called nozzle. Modern vacuum cleaners are usually equipped with different nozzles for different surfaces: In addition to the wide floor nozzle (possibly with switch option for carpets and smooth floors), there are often special furniture brushes or narrow crevices, which can suck the dust even from narrow spaces.

Here we show the suction times using the example of a classic floor nozzle: This usually has on its underside small brushes and when you drive with her over the carpet, the fibers are moved back and forth, the dust is whirled up and through the nozzle opening on the Suction hose sucked into the dust bag.

The dust bag is made up of several layers of paper or special nonwovens that, while allowing the air drawn in, to filter out the dust that swirls around it. So the dust collects in the dust bag and the sucked air comes, now cleaned of dust, back out of the vacuum cleaner out.

Vacuum Cleaner Engine

Intake opening, suction hose, who or what is actually sucking in the vacuum cleaner?

Basically, sucking works the same as sucking water with a straw: by creating a negative pressure in the mouth that carries the water through the straw into the mouth.

In the vacuum cleaner, the vacuum is generated by a motorized fan: when the power cord is plugged in and the motor is turned on, it converts electrical energy into mechanical energy – in this case, a rotary motion. This is taken up by the blower.

The blower usually consists of a centrifugal compressor whose rotating blades produce a vacuum according to the principles of fluid mechanics. This negative pressure prevails in the entire vacuum cleaner interior, where the dust bag is located, and is transmitted via the suction pipe to the nozzle.

The basic question behind this neutral formulation is most likely to be: Have I done the spider with it once and for all Or is there a danger that the animal crawls out of the vacuum cleaner?

It is unlikely that the spider survives the roller coaster ride through the vacuum cleaner. Even better, the bigger the spider, the lower its chances of survival! Spider in the vacuum cleaner.

Structure And Functionality Of Air Compressor

The compressor – Functionality & Structure

A compressor * is used to machine different gases. One calls it therefore also as a compressor. So-called reciprocating compressors are common compressors in the hobby and home area. Similar to an air pump or car engine reciprocating compressors work alternately between suction and compression of the gas. The piston sucks in needed air and presses it together in a housing which tightly surrounds it.

Compression is used to reduce the volume of gases. The aspirated gas volume is minimized by the compressor by its operating pressure. This process of compression causes the gas in the pressure to rise, the gases are also heated.

Construction of the compressor

The main component of a best air compressor is its engine, which drives the compressor. Common usage often refers to the compressor itself as a compressor, although it is only part of the compressor.

The compressed air from the compressor is not discharged directly. A pressure vessel into which the compressed gas is pumped, distinguishes the compressor substantially from the air pump and engine and has several advantages.

For example, the pressure vessel can store larger amounts of air than the piston of the compressor promotes throughout. This air can then be expelled as a total amount. Nor does the compressor motor have to be in continuous operation.

A pressure gauge in the superstructure of the compressor is used to monitor the pressure in the boiler of the compressor. When operating pressure is reached, it is possible to use the respective tool.

 Elements of a reciprocating compressor

Main elements of a reciprocating compressor, In addition, the compressor can also react to the boiler pressure. If the pressure drops below the set minimum pressure, the compressor’s engine starts to fill the compressor boiler sufficiently with compressed air. When maximum pressure is reached, the pump is stopped. In the case of a dangerous overpressure, a safety valve in the structure of the compressor opens to release the pressure.

How does the reciprocating compressor work?

Before we look at the operation of a reciprocating compressor *, let’s take a look at its structure. The following section is used for this purpose.

Construction of a piston compressor

Inside a cylinder, a piston moves back and forth. A seal seals the piston towards the cylinder wall. The retraction of the piston sucks in air through the inlet valve and advancement closes this valve again. Thus, the air is compressed. An emission of air takes place through the exhaust valve of the reciprocating compressor.

How a piston compressor works: suction & compression

The most commonly used compressors include, in addition to the reciprocating compressor and the screw compressor. It differs significantly in structure and function, but should not be considered in detail on this page.

The operation of the compressor: About operating pressure and delivery quantity

Compressors are characterized by their pressure and the achievable delivery quantity. The delivery quantity is defined as the volume of air delivered per time unit. The usual unit of delivery is m3 / min, or liters / min in the case of smaller plants.

Misleading, although often in use, is the definition of theoretical suction power as the product of displacement and speed. By neglecting the volumetric filling level, no statement is made about the actual flow rate.

Relevant characteristics of the function of the compressor

Important parameters of the reciprocating compressor and thus the functioning of the compressor, are delivery quantity, operating pressure, pressure ratio and degree of delivery.

While the delivery quantity describes the volume of the expelled gas per unit of time, the operating pressure is defined as the achievable excess pressure.

The pressure ratio is determined by the ratio of final pressure to suction pressure and the degree of delivery shows the relationship of conveyed to theoretically achievable volume flow.

To compare different compressors *, which differ in design, operating points or the operation of the compressor, the standard volume flow is used. This converts the volume flow of the compressor to standard conditions with regard to temperature, humidity and pressure. Thus, the individual function of the compressor is comparable.
