How VoIP Phones Work In the past, phones were wired to an on-premises Private Branch Exchange (PBX). This bulky machine would handle all routing and ensure each call reached its proper destination. VoIP phone features far exceed those available on old PBX systems. Since VoIP phones process telephone calls from the internet, or the cloud, the technology employs existing computer network cabling or Wi-Fi to access telephone networks. No additional copper wiring is needed to use your VoIP business phone service. Your phone number can stay the same as before, so there is no expense in changing it. Because of this, making a VoIP phone call is simple. Just pick up the handset and dial a number. The technology is designed to make it simple, not more complicated. This same idea applies to receive a VoIP phone call. It’s the same as any other call.

What exactly is a VoIP phone system You use your phone system (also known as a PBX) every day, so you already know that phone systems are responsible for handling your call control and managing your connection to your telephone service provider. What you might not be familiar with is VoIP. VoIP is short for Voice over Internet Protocol. VoIP is a way to make calls across your Local Area Network (LAN) and or Wide Area Network (WAN). The technology behind VoIP converts your analog voice into digital packets which are then sent across a network using the Internet Protocol (IP) to their end destination. VoIP is most commonly associated with making calls across the Internet. As you've probably guessed, a VoIP phone system gets connected to your LAN. It uses your LAN as the backbone of the system – connecting your VoIP phones and your VoIP service provider to the VoIP PBX. That makes a VoIP phone system a phone system that uses IP technology to handle your call control and manage your connection to the Wide Area Network over which your VoIP service comes. Even though a VoIP phone system uses VoIP and is connected to your LAN most systems can connect directly to the Publicly Switched Telephone Network (PSTN). This gives you the ability to use both VoIP and the PSTN for your calling.

Structure and application classification of vacuum furnace Vacuum furnace is a kind of heating equipment in vacuum environment. In the furnace sealed with metal cover or quartz glass cover, pipes are used to connect with high vacuum pump system. The vacuum degree of furnace can reach 133 × (10-2 ～ 10-4) H. The heating system in the furnace can be directly heated by resistance furnace wire (such as tungsten wire) or by high frequency induction heating. The highest temperature is about 3000 ℃. It is mainly used in ceramic firing, vacuum smelting, degassing and annealing of electric vacuum parts, brazing of metal parts, and ceramic metal sealing, etc. Next, the vacuum furnace manufacturer will briefly introduce the structure and application classification of the vacuum furnace: the vacuum furnace is generally composed of furnace, electric heating device, sealed furnace shell, vacuum system, power supply system and temperature control system. The sealed furnace shell is welded with carbon steel or stainless steel, and the joint surface of detachable parts is sealed with vacuum sealing material. In order to prevent the deformation of the furnace shell and the deterioration of the sealing material after heating, the furnace shell is generally cooled by water cooling or air cooling. The furnace is located in the sealed furnace shell. According to the purpose of the furnace, different types of heating elements are installed in the furnace, such as resistance, induction coil, electrode and electron gun. Crucible is installed in the furnace of vacuum furnace for melting metal, and some are also equipped with automatic pouring device and manipulator for loading and unloading. The vacuum system is mainly composed of vacuum pump, vacuum valve and vacuum gauge.

How to implement brazing process in vacuum furnace? During brazing operation in vacuum furnace, the weldment with welding is put into furnace (or brazing vessel), the furnace door is closed (or brazing vessel cover is closed), and vacuum is pre pumped before heating. Start the mechanical pump first, turn the steering valve after the vacuum degree reaches 1.35pa, turn off the direct channel between the mechanical pump and the brazing furnace, make the pipeline connect with the brazing furnace through the diffusion pump, rely on the mechanical pump and the diffusion pump to work for a limited time, pump the brazing furnace to the required vacuum degree, and then start heating. During the whole process of heating, the vacuum unit should work continuously to maintain the vacuum degree in the furnace, offset the air leakage at various interfaces between the vacuum system and the brazing furnace, release the gas and water vapor absorbed by the furnace wall, fixture and weldment, and volatilize the metal and oxide to reduce the vacuum drop. There are two kinds of vacuum brazing: high vacuum brazing and partial vacuum brazing. High vacuum brazing is very suitable for brazing base metal (such as nickel base superalloy) whose oxide is difficult to decompose. Part of vacuum brazing is used for base metal or solder volatilization under brazing temperature and high vacuum conditions. When special precautions must be taken to ensure high purity, vacuum cleaning method should be used before dry hydrogen brazing. Similarly, the dry hydrogen or inert gas cleaning method before vacuum pumping will help to obtain better results in high vacuum brazing.

Welding effect of vacuum brazing furnace Vacuum brazing means that the workpiece is heated in a vacuum chamber. It is mainly used for the welding of high-quality products and easily oxidized materials. The vacuum brazing furnace consists of a pressure vessel with a cylindrical side wall and a door whose size and position are designed to close one end of the cylindrical side wall. The workpiece handling system is installed on the pressure vessel door to support metal workpiece for heat treatment or brazing. The workpiece processing system includes a device for turning the workpiece during processing. The vacuum system can be connected to the workpiece so that the pressure inside the workpiece is lower than the atmospheric pressure during brazing. Brazing in vacuum furnace is a new brazing method without flux in vacuum. Because brazing is in vacuum environment, it can effectively eliminate the harmful influence of air on the workpiece, so it can be successfully brazed without flux. It is mainly used for brazing those hard to braze metals and alloys, such as aluminum alloy, titanium alloy, superalloy, refractory alloy and ceramics. The brazed joint is bright and compact with good mechanical properties and corrosion resistance. Vacuum brazing equipment is generally not used for needle welding of carbon steel and low alloy steel. Vacuum aluminum brazing furnace is mainly composed of vacuum brazing furnace and vacuum system. There are two types of vacuum brazing furnace: Hot fireplace and cold fireplace. The two types of furnaces can be heated by natural gas or electric heating, and can be designed as side loading furnace, bottom loading furnace or top loading furnace (Kang type). The vacuum system can be used in general. The vacuum system mainly includes vacuum unit, vacuum pipeline, vacuum valve, etc. The vacuum unit is usually composed of rotary vane mechanical pump and oil diffusion pump. Only using mechanical pump can get vacuum degree lower than 1.35 × 10-1pa. In order to obtain high vacuum, the oil diffusion pump must be used at the same time. At this time, the vacuum degree of 1.35 × 10-4Pa can be achieved. The gas pressure in the system is measured with a vacuum gauge.

Mixing principle of vacuum pump oil According to the understanding of the vacuum pump factory: at present, the vacuum pump oil is not supplied in time in the market or there is a lack of suitable varieties in the market. Sometimes, there are problems of mixed use of vacuum pump oil in the process of using, including domestic oil and foreign oil, different types of oil in domestic oil, different manufacturers or different brands of the same kind of oil, mixing of new oil with "old" oil in use, etc. At present, many users have a lot of randomness in choosing alternative oil or mixed use of vacuum pump oil. However, it should be noted that different types of vacuum pump oil have different physical and chemical properties. Its chemical composition, viscosity, acid value and various additives (anti-wear agent, preservative, antioxidant, rust inhibitor) and other main components and indicators directly affect the operation of the machine. Zhaoqing vacuum pump factory is located here The improper use of the pump will not only remind the user of the use of oil, but also change the service life of the pump. Therefore, the following principles should be observed when using the mixed oil.
