Air Compressor Working Principle

Air compressors are of many types here we discuss some of them and their working principle.

air compressor

Piston-Type Oil-Free Air Compressor Unit

Piston by the oil-free air compressor drive system, compression system, cooling system, lubrication system, control system and security system.

Compressors and motors bolted to the base, the base with anchor bolts fixed on the basis.

During operation, the motor directly drives the crankshaft through the coupling and drives the connecting rod, the cross head and the piston rod so that the piston reciprocates in the cylinder of the compressor to complete the process of inhalation, compression and discharge.

The machine is a double-acting compressor, that is, the piston up and down the air intake, compression and discharge.

Screw Air Compressors

Screw air compressor driven by the screw head, the motor, oil separator barrel, the cooling system, air conditioning system, lubrication system, and a valve control system components.

The machine is installed in a box, self-contained, directly on the flat cement floor can be, without the need to anchor bolts on the foundation.

Screw head is a kind of double-axis displacement rotary compressor head. 1 pair of high-precision main (male), sub (female) rotor mounted horizontally and parallel inside the chassis, the main (male) rotor has 5 teeth, while the Vice (negative) rotor has 6 teeth. The main rotor diameter, deputy rotor diameter is small.

Tooth formation spiral, both inter meshing. Both ends of the main rotor and the auxiliary rotor are respectively positioned by bearings.

Working motor directly through the coupling (or belt) with the main rotor, the two rotors inter mesh with each other, the main rotor directly driven with the deputy rotor rotation.

The coolant is sprayed directly into the rotor meshing part from the nozzle at the lower part of the compressor housing and mixes with the air to remove the heat generated by the compression to achieve the cooling effect.

At the same time, a liquid film is formed to prevent direct contact between the rotor and the metal and to close the gap between the rotor and the casing.

Coolant

Sprayed coolant also reduces the noise generated by high-speed compression.

The main components of screw air compressor screw head, oil and gas separation barrel. Screw head suction through the suction filter and the intake control valve, while the oil injected into the air compression chamber, the head cooling, sealing and screw and bearing lubrication, the compression chamber produces compressed air.

After compression,  OR best portable air compressor  resulting gas-oil mixture is discharged into the oil-gas separation tank. Most of the oil is separated from the oil-gas mixture due to mechanical centrifugal force and gravity.

Air passes through the oil and gas separation cartridge made of borosilicate glass fiber and almost all of the oil mist is separated. The oil separated from the oil separator is returned to the screw head through the return pipe.

The oil return pipe is equipped with oil filter, oil return through the oil filter, the clean oil flow back to the screw head. After the oil is separated, the compressed air leaves the reservoir through the minimum pressure control valve and enters the after cooler.

After the cooler cooling the compressed air discharged to the gas tank for each gas unit. Condensation of water concentrated in the gas tank, through automatic drainage or manual discharge.

An Interesting Article About Proxy Site Working

proxy coding

If I access the A website through a proxy, for A, it treats the proxy as a client, completely undetectable of the real client, which achieves the purpose of hiding the client IP.

How The IP Changed By Using Proxy Site

Of course, the agent can also modify the HTTP request headers, by X-Forwarded-IPtelling a true client server IP such as custom head. However, the server can not verify that this custom header was actually added by the proxy or the client modified the request header, so extra care should be taken when getting the IP from the HTTP header field. This part can refer to my previous ” HTTP request header X-Forwarded-For ” article.

Explicitly designated browsers

Explicitly designated browsers to the browser, you need to manually modify the browser or operating system settings, or specify the PAC (Proxy Auto-Configuration, automatic configuration file) automatically set, and some browsers support WPAD (Web Proxy Auto discovery Protocol, Web Proxy auto-discovery protocol). Explicitly specify the browser proxy This method is generally called forward proxy, the browser enables the forward proxy, the HTTP request message will make some changes to avoid some of the problems of the old proxy server, this part can refer to My previous ” Http request header Proxy-Connection ” this article.

Resolution To The Proxy Server IP

Another situation is that when visiting A website, the actual visit is the proxy. After the proxy receives the request message, it sends a request to the server that actually provides service, and forwards the response to the browser. This situation is generally referred to as reverse proxy, which can be used to hide server IP and port. After the general use of reverse proxy, you need to resolve the DNS domain name resolution to the proxy server IP, then the browser cannot detect the existence of the real server, of course, do not need to modify the configuration. Reverse Proxy is the most common way to deploy a Web system, such as this blog is to use Nginx’s proxy_passfeatures will forward the request to the browser behind Node.js service.

Coding

After the above code is run on the local 8888open port for the HTTP proxy service that parses the request URL and other necessary parameters from the request message, the new request to the server and forwards the request agent received a new request, final Then the server response back to the browser. Modify the browser’s HTTP proxy to 127.0.0.1:8888access the HTTP Web site and then, agents can work properly.

However, after using proxy site, the HTTPS website is completely inaccessible. Why? The answer is very simple, this agent provides HTTP service, and there is no way to carry HTTPS service. So whether this proxy to HTTPS on it? Obviously not, because the essence of this proxy is a middleman, and HTTPS site certificate authentication mechanism is hijacking nemesis nemesis. In normal HTTPS service, the server does not authenticate the client’s certificate. The middleman can successfully complete the TLS handshake as the client and the server. However, the middleman does not have the private key of the certificate. In any case, the server cannot establish a TLS connection with the client. Of course, if you have a certificate private key, the proxy certificate corresponds to the HTTPS website of course no problem.

What is Proxy Site and How It Works?

proxy linkage

What is Proxy site?

Web Proxy Server, known as an online proxy or online proxy. Web page proxy is a child of proxy server program running on the web page.

Without any setting, the advantages of accessing the Web server by selecting the Web address have become the most popular proxy access method nowadays.

A web proxy is a common child of the agent. The web proxy provides the client with a cache of web pages and files on the remote site so that the client can browse the remote site more quickly and securely.

Some web proxy sites keep updating daily to ensure speed.

Is Proxy Is A Middle Linkage For Boosting Web Speed?

Web proxy principle is to receive the browser to the remote site browsing time, the agent started to look at the current server cache Web site is returned to the user’s browser client.

If the current server does not cache the remote server, the agent automatically reads the remote site, submits the data to the client, and caches the data for the next browsing requirement.

The agent automatically deletes the cache based on cached time, size, and fetch records.

There are two ways to delete, one is to delete the oldest data, and one is to delete the least extracted cache. These two methods can, therefore, be used in combination.

Web proxies use different and complicated scripts to bypass filters and firewall websites.

Users using online proxy services are very simple, do not need to be a browser, and do not need to install additional software, just visit the online acting websites, and then you can enjoy free agency services.

In mainland China, some sites are blocked, web proxy access can be viewed.

Advantages of Web Proxy

A web proxy is a web proxy with the function of the anonymous proxy server. When an online proxy is running on the server, the web proxy can be used as a springboard to surf the Internet. It does not only make the Internet more secure.

The web proxy can filter the content of remote sites. Some censorship software is similar to the web proxy.

For some purposes or protection, some web agents are so far the content of the site. For example, Skweezer can reschedule pages to provide browsing for mobile and PDAs.

Network administrators thus often use agents to prevent virus and reaction site content.

These programs are usually written in PHP or CGI programming language. An agent written by CGI is often used to break the network blockade of a company or school.

Agents wrote through CGI hide the client’s IP, so users can anonymously access remote sites.

The proxy written by PHP uses 64-bit encryption technology, uses the fsockopen function to access the target URL through the HTTP access class, and then processes the HTML code and prefixes each link thereafter And CSS, Javascript files.

Through some web proxy download software, you can filter out some dangerous files containing viruses and Trojans, which can make the browsing experience more secure.

Why the phone is installed when the game shows the application is not installed

1, the first idea is that the system has residual program may not be removed clean can not be installed, so use RE browser search program related keywords, find all the relevant files and directories are deleted, and then restart and then install the program, the result Invalid;
2, think of a backup before, so open the titanium backup, find the relevant software, restore: the first choice is the program + data, restore failed, and then select a separate restore procedure, suggesting that the restore was successful, but not in the system See restore the successful program, so fooled (here I did not try to restart the system, do not know if the reboot after restore will not be effective, interested friends can try ha ~);
3, no way, only To Google, the first to find is the most successful way: [Storage mode connected to a computer or use Root Explorer to find the SD card directory. Android_secure folder, there should be a smdl2tmp1.asec, it may be other names, In short and the normal program naming format is obviously not the same file, delete, try again to install the software But I either system or SD card can not find the relevant directories and files, so this method is completely useless to me;
4, the second method: [If you are prompted to install the application fails on the PC side, please check Did not install the corresponding Android phone USB driver , the general use of 91 cell phone assistant or pea clip will automatically help you install the phone driver], I was the phone side tips failed, and my driver is properly installed, the pea pods are used properly, so this
Has nothing to do with me; 5, the third method: [View phone settings – application – unknown source is checked, otherwise it will lead to some non-electronic market applications can not be installed], I checked, so this I have nothing to do;
6, the fourth method: [with the system comes with the program management view SD card on the program, some programs turned out to be no color icon, the original is that these no icon software in trouble, these no icon software Is some of the previous is not properly installed or uninstall incomplete software data, if you install error will be reported, and now we use the system comesSoftware management to uninstall them clean, install the software again will not go wrong], but I use the system comes with the program management even any icon can not see, so this method is useless to me;

8, the sixth method: [upgrade installed programs prompt “application is not installed” a small part of the software upgrade will appear, you can only uninstall Out of the old version, and then install the new version], I simply can not find the uninstall, so useless;
9, the seventh method: [in the Settings – Development – to allow simulation sites tick, OK music] or a useless;
10, eighth method: [mobile phone connected to the computer and then open 91 mobile assistant , just install an application, select the installation path for the phone memory], I was 2.1 system software is installed in the original “within “In, so this is useless;
9th Method Download lucky patcher apk from apk sites and open and install and then restart the phone;
12, the tenth method: [direct factory reset ], which is a way I do not want to do, in theory, it should be effective.
After all the above attempts, the problem still can not be solved, that depressed, do I have to restore the factory? Hesitate again and again, have begun to prepare reloading, the results in the search for Andrews systemThe installation of the principle when I actually found a way to solve the problem that has troubled me for a long time, let’s look at the solution below:
In fact , the installation of the Android system is to copy the APK file to the APP directory and give permission , The backup is also the APK files and related data files copied out, in accordance with this principle, I did the following:
1, first download the application APK installation package on the SD card;
2, the APK file renamed com.xxx .xxx.apk (compared to the system directory under the APP file name)
3, into the app folder will modify the permissions after the installation
4, still “program is not installed”
At this point, all possible solutions to try to solve the solution: Decisively give up the software!

What is Hosting and About Shared, Vps and Cloud Hosting

Shared hosting

When a hosting company is set up that will host several web servers, this practice is called co-hosting. This is not a very expensive accommodation designed for small greedy websites RESSOURCES .

Picture Keyboard PC Share Host Blogpascher

advantage

Shared hosting ( sharing ) is a good choice for some WordPress sites. The following benefits:

This is the most affordable option, often starting at $ 5 per month
Security and server maintenance will be managed by you
You most need to have your tools installed
Creating a website is easier and more convenient than any other choice.
If you have problems with a shared hosting plan, you can contact your $1 Web Hosting  company’s support team and they can handle almost any issue that does not require you to have a specific skill in development.
Disadvantages

Although it is very easy to get started with hosting, there are many disadvantages:

Security can not be guaranteed – because you do not know your neighbors ( those who share your server ), they can not always take you and they are the same security precautions against piracy that could jeopardize the entire server and everything that includes you Website. If you do not have a dedicated IP address, your site may be blacklisted if the server’s shared IP address is blocked due to one of your neighbors (on the server).
You have to set limited – by sharing the host, you will often have root access, some files are hidden there and you may not be able to access the advanced settings. For example, if you run PHP memory or you want to make your site to test the flow of information, you will not be able to do it.
Your Website Resource Sharing – Because of the server that you share with other users and want to unblock proxy sites, this means you will share resources such as bandwidth. If those who share your server have more bandwidth than you, it may compromise the accessibility of your website on the same server often sharing the same bandwidth.
It’s not limitless – many hosting companies pack “infinity” in their hosting plans and it sounds like there’s no cap for resources, but this is certainly not the case if you check the service for them. In most cases, the hosting company can decide to stop your site if you use too many resources on the server.
When is the best?

Although the shared hosting weaknesses are enough for some users to transfer in some cases, this is the best choice for your website. If you only need to install some plugins and some web pages on your site instead of looking for a long period of traffic congestion, it may be your best solution.

For example, if you create a website to share some details about upcoming weddings, such as using a shared blog, your family and updated dates, times and places, site friends, shared hosting is indeed the best solution .

Because you do not think of a lot of traffic, you do not need a powerful site in these situations, sharing a host is usually sufficient.

Virtual Private Server (VPS)

As a hosted share, you are still a shared server when you choose a VPS, but there are also a handful of users per server. If we still share resources, we must say that in this case, there are also a few people’s resources.

There are also two main types of VPS hosts: managed and unmanaged .

Managed VPS ( Management ) means that your Hosting Germany company needs more to get into the maintenance server, including security concerns, the need for development tools for your website, and other services needed for accommodation.

In addition, VPS hosting ” unmanaged ” means that you are responsible for all your accommodation in all these areas, and you may not be able to support too much technical support in the event of a problem.

VPS server

benefit

There are many reasons to choose a VPS hosting plan:

You have more resources – Since you rent a larger part of the server, you will have access to more resources.
You have access to all the parameters – in most cases, you should have root privileges and you will be able to view all hidden files and access all parameters. If there is anything you can not access your hosting company it’s easier to make it for you, unlike shared hosting.
It is more scalable – in most cases you can if you find you need more resources without having to migrate your site to a new server instead of having an update plan that limits shared hosting.
In most cases, VPS hosting is still quite affordable, although some deals are not cheaper to share hosting. It is often possible to see a plan averaging about $ 100 a month.

Disadvantages

Even if you have more freedom, and before you get there, you should consider something important:

Security is not guaranteed – since you’re still sharing servers, your site can still suffer damage that occurs elsewhere on the same server, especially if they are hacked.
You’re still a shared server – even if you’re a lot less person sharing, it’s worth the resource limit, even more important.
You can not always get help with technical support, especially if you choose a plan that is ” unmanaged .”
When is the best?

If you want to run one or more sites, each site needs a few pages of installed plugins, a VPS host is usually a good solution. If you plan to have thousands of monthly visitors, this is also a good plan. It is also very spacious and good work.
