The realization of vacuum brazing furnace automation
Vacuum brazing furnace spray subject to the circular structure, surface passivation treatment, which ensure the beautiful appearance, also make soldering flux recovery effect is better, which can effectively prevent soldering flux, in the case of spray flux indoor accumulation, cleaning is also very convenient. Circular structure USES the real high pressure fan, pressure can reach 280 mbar, cooperate with special wind mouth, the wind speed can reach 50-200 - m/s, which can effectively remove redundant solder surface residues. Vacuum brazing furnace of a high degree of automation, below we come to the realization of the vacuum brazing furnace automation:1, vacuum brazing furnace spray mixing system contains a lot of humanized design, solder recycling barrel equipped with filtering impurities, can filter most of the iron xu. Barrel designed deep barrel structure, which can effectively prevent solder overflow by stirring, and affect beautiful. Upper barrel equipped with omron level control, but the lack of liquid alarm.2, the structure of the brazing furnace using fiber (cotton) around, verified by long-term considerations, insulation performance is better, can save heating time 2 to 3 hours, managing electric energy 10-20% while working for a long time, its main performance in response speed, low heat storage and heat preservation performance is good, had no effect on inflation, etc.3, main part furnace brazing furnace, furnace is made of a 12 m in forming, namely only two side 2 weld, folding strengthen V groove at the bottom of the two.4, slag removal chamber equipped with nitrogen gas preheating system, because there are high temperature slag removal chamber, in 500-600 ℃, when not being used, the high temperature also need emitted, resulting in energy loss. Now through slag removal chamber, internal installation scattered tropical, nitrogen cycle special process structures, such as nitrogen can be preheated to 350-400 ℃, and indirectly reduce the brazing furnace to nitrogen loss to the heat and power consumption.5, for the energy-saving design of nitrogen, nitrogen losses mainly in the feed port and discharging port, how to ensure that the nitrogen loss is the key to save the nitrogen. Regular design can make the nitrogen from metal curtain on both sides of the overflow, metal curtain roll after using for a long time will appear, cannot achieve the desired effect. Now my company through from the top insert metal curtain, and high temperature polyester cloth, make furnace at two sides with the metal curtain connecting more closely, metal curtain after using for a long time will appear curly, but we have high temperature polyester cloth, outer spillover will still blocked the nitrogen.6, fully automatic electric control system, two undisturbed switching procedures manual and automatic mode, can accurate records of each area of temperature curve, can copy computer analysis with EXCEL at the same time. The procedural control of the brazing furnace, can be very convenient setting the heating time, needed to make a contribution to protect the furnace. In view of the different temperature requirements of different products, with a key switch technology products, and other functions. Touch screen for each line, motor, temperature control, frequency converter fault for real-time monitoring, timely detection alarm in time, and in the form of Chinese display and storage.7, remote control function, in the case of equipped with cable, can use the computer, mobile phones connected to the touch screen in real time, can see or remote control, also can be used as a remote maintenance. Brazing furnace main parts can also be video view (optional).
