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.

Cover

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.

Construction of a screw compressor

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.

Best Flat Iron For Natural Hair

The history and development of the straightener

The straightener eliminates frizzy curls and gives users the dream of straight hair.

For our leaderboard, our experts have reviewed countless tests and comparative reviews on the Internet, and have been able to give ratings for materials, temperatures, heat levels, and more.

Man tends to beautify his appearance since his beginnings. Already 100,000 years ago, people felt the desire to decorate their bodies.

This desires expanded over time more and more, and today we have all possibilities to order our appearance care.

The latter is not only a sign of an attentive nature and disciplined character, but also of good health. Well-groomed and shiny hair emits exactly that, which is why they almost serve as bait.

Then, considering that people always want what they do not have, we find the answer to the question of why and when the first flat iron was invented.

The first Best Flat Iron for Natural Hair was invented by the Frenchman Marcel Gateau. At that time, it did not have the current shape, because it was actually a curl wand, which later evolved.

Two small Metastable were in a scissors-like position and were heated by the open fire. Then came strands of hair between the scissors, which were either smoothed or curled.

Since these procedures hid many dangers, the flat irons had to be refined further and further

The straightener eliminates frizzy curls and gives users the dream of straight hair. For our leaderboard, our experts have reviewed countless tests and comparative reviews on the Internet, and have been able to give ratings for materials, temperatures, heat levels, and more

So the hairy affair could not be stopped. The device is designed like a pair of pliers, with the individual jaws of the pliers on the inner sides provided with hot surfaces of metal or ceramic. The system is simple, but perhaps that’s why it was discovered so late.

Between the individual pliers then a strand is inserted and smoothed. It can also be used different attachments, such as wave attachments, so that the hair not only smooth, but also look a bit more unusual.

Each strand is naturally placed all the way to the point in the acting and hot hands of the forceps. Then either the smooth hair can transform into curly hairstyles, or transform the curly curls into a smooth and shiny mane.

For whom is a straightener suitable?

In addition to hair dryer, cosmetics, shampoo and brush, there is another important utensil, which is simply not to be missed in many bathrooms.

For daily styling plays a very important role for women. The new day starts at work, the women attach great importance to their own hair.

The flat iron is in many bathrooms today an everyday equipment. So this is not only known from the visit to the hairdresser, in which he handles this practical item. But for whom is a modern flat iron really suitable, which target group do the manufacturers want to address with the models?

What Are The Main Features Of HTTP?

what is http

What Is TCT/IP Protocol?

  • HTTP is built on the TCP / IP protocol and the default port number is 80
  • HTTP is a connectionless stateless of
  • HTTP packets
  • Request message

The HTTP protocol is transmitted in ASCII code and establishes an application layer specification over the TCP / IP protocol. The specification divides the HTTP request into three parts: the status line, the request header, and the message body. Similar to the following:

<method> <request-URL> <version>

<Headers><Entity-body>

HTTP defines different ways to interact with the server, there are four basic methods, namely GET, POST, PUT, and DELETE. Add, change, delete, and delete operations on the network, and the HTTP GET, POST, PUT, and DELETE on operations.

1.GET is used for information acquisition and should be safe and idempotent.

The so-called safe means that the operation is used to obtain information instead of modifying information. In other words, GET requests should not generally produce side effects. That is to say, it will only obtain obtainable resource information, just like a database query, it will not be modified, add data, will not affect the state of the resource can get by proxysite.

Impotence means that multiple requests to the same URL should return the same result.

Example of a GET request message:

 GET / books /? Sex = man & name = Professional HTTP / 1.1

 Host: www.example.com

 User-Agent: Mozilla / 5.0 (Windows; U; Windows NT 5.1; en-US; rv: 1.7.6)

 Gecko / 20050225 Firefox / 1.0.1

 Connection: Keep-Alive

  1. The POST indicates that the request to change resources on the server may be modified.
  2. POST / HTTP / 1.1
  3. Host: www.example.com
  4. User-Agent: Mozilla / 5.0 (Windows; Windows NT 5.1; en-US; rv: 1.7.6)
  5. Gecko / 20050225 Firefox / 1.0.1
  6. Content-Type: application / x-www-form-urlencoded
  7. Content-Length: 40
  8. Connection: Keep-Alive
  9. Sex = man & name = Professional
  10. Note:

The amount of data that GET can submit is limited by the length of the URL, and the HTTP protocol specification does not restrict the length of the URL. This limit is limited by the specific browser and server

Theoretically speaking, POST is not limited in size, and the HTTP protocol specification has no size limit. For security reasons, server software will impose certain restrictions when it is implemented.

The Biggest Contribution To Network Security Is Free To Upgrade Win10

Netease Technology News November 18, according to foreign media reports, Microsoft CEO Satya Nadella on Tuesday described to the public the company’s bold measures to protect the safety of Windows users. However, Microsoft’s greatest contribution to network security is a free upgrade to Windows 10.

“The network security situation was quite severe in 2015,” said Nadella at the annual meeting of the Microsoft Government Cloud Forum in Washington, DC. “The most serious 8 or 9 data breaches have endangered the safety of 160 million data records,” and the global economy has lost more than $30 trillion.

Adoption Of Hope

When talking about the company’s countermeasures, It is pointed out that Microsoft will create a “Network Defense Action Center” internally to analyze possible threats and coordinate the company’s countermeasures. Microsoft has set up a corporate network security division to provide threat assessment and monitoring services.

Regardless of whether these practices are effective, the key to cybersecurity for most consumers is to install the latest version of the new operating system, which does not necessarily take time or money.

That’s Microsoft introduced a free upgrade system this year. It spares no effort to turn Windows from a product to a service. Upgrade patches are also included in this new program and will be automatically installed in the background.

Although free, there are still quite a few users who are not using the latest Windows system. According to Microsoft’s statistics, about 1.5 billion people use Windows in the world, but only 110 million of them have upgraded to the latest Win 10

How You Will Finalise About Best Orange Juicer?

Features Of Best Orange Juice Extractor 

According to the above table, the home recommended Taboos buy hundreds of juice or a thousand or so centrifugal juicer, cost-effective, more versatile, basically no problem dealing with all kinds of fruit is there will be a general difference of processing that there is very good.

If you just want to buy a home juicer, then you absolutely do not need to consider the mixer (e sand ice machine) and squeezed orange juice machine, because the kind of fruit that can be handled too limited. Of course if you say that I am a local tyrant. I don t want to buy it. I can ignore this sentence.

If you like watermelon very much, then you must choose the juke machine. Because the best machine for processing watermelon is the juice machine.

Recomendation About Juicer Machine

In addition, the juice machine purchase has a personal recommendation: Do not buy expensive, the original juice machine technology is simple, there is no big difference.

You buy a domestic big name with a warranty on it, and some South Korean imports there is no big difference in the brand juicer above 2,000 yuan.

However. If you are lazy and not willing to clean the machine, we recommend that you buy a centrifugal juicer.

Because the boot directly pour water can be cleaned. Only when it will not be used for a long time only need to thoroughly clean it there are no major problems with handling several different fruits in a row.

But to buy some centrifugal juicer may need to buy a little more expensive,  because the centrifugal juicer motor difference is still a little big, which is the cost of investment than the original juice The place with higher confidentiality.

If you are interested in learning more about Best Orange Juicers, please see the detailed answer below: I roughly reviewed the existing answers, and the answer was actually moving the food processor out I really couldn’t help.

No matter in any professional field, there is an iron rule that reminds you: If the machine has a lot of functions and the feeling is all-powerful, it must be in terms of product quality and the ease of use of each function switch or other.

Something that you can’t think of is going to have a big problem. To put it bluntly, every function was picked up. But it was not fine.

This kind of machine can make commercial chicken ribs (may only use one of the single functions) home trouble (various functional switching trouble, or some parts of the storage is easily lost), each field none of the strengths are mediocre, and it is boring.

And as far as I know things are not cheap and they are simply used to show off skills and are not practical. In the answer above.

The classification is clear and the analysis is relatively in place, basically in line with what I know about the juicer classification. However, my answer will add a lot to his base.

How The Proxy Server Works

proxy server

Proxy also known as network allows a network terminal (typically clients) via this service with another network terminal (normally a server) non-direct connection.

Some gateways, routers and other network equipment with network proxy site. Agency services are generally believed to help protect the privacy or security of network terminals and prevent attacks.

Agency services computer systems or other types of network terminal called proxy server.

A complete proxy request process is as follows: The client first establishes a connection with the proxy server, and then requests to establish a connection to the target server or obtain the specified resource (for example, a file) of the agent, is a special kind of network service that target server according to the proxy protocol used by the proxy server.

In the latter case, the proxy server may download the resource of the target server to the local cache.

If the client wants to obtain the resource in the proxy server’s cache, the proxy server does not want to send the request to the target server but directly return cached resources.

What Is Proxy Protocol?

proxy server and firewall

Some proxy protocols allow the proxy server to change the client’s original request to the original server to satisfy the needs of the proxy protocol.

Proxy server options and settings in a computer program typically include a “firewall” that allows the user to enter the proxy address, which covers their network activity and allows filtering across the Internet for network access.

Function of The Proxy Server

  1. Increase the speed of access: usually the proxy server is set to a larger buffer, when the outside information is passed, but also to save it to the buffer, when other users access the same information, then directly from the buffer remove the information, passed to the user, in order to improve access speed.
  2. Control access to internal resources: If a university FTP (provided that the proxy address within the allowable access to the resources), the use of educational network address free proxy server, you can use for educational network open all kinds of FTP Download and upload, as well as various types of information sharing and other services.
  3. Filtering content: for example, limiting access to specific computers, translating data from one language to another, or defending offensive access to both sides of a proxy server.
  4. Hide real IP: Internet users can hide their own IP through the proxy server, from attack. However, it is only one agent to guarantee safety. A safer method is to use a specific tool to set up an agent chain (e.g. Tor).
  5. Break their own IP access restrictions: visit foreign sites. China Education Network and 169 network users search as Internet users can visit foreign websites.
  6. Break through the content filtering mechanism to restrict access to filtered sites. Restrictions on internet access in China search the browser.

But every time the National Day, the two sessions and other sensitive period, the Great Firewall of the firewall wants to improve the blockade, most of the proxy server and proxy software will not be able to connect. (Such as: gate, free door, unbounded browsing, etc.)
