CAS-400Excellent Supersonic Arc Spraying Equipment

     Supersonic Arc Spraying is a newest technology, it is developed on the basis of traditional Arc Spraying and the coating of it has more excellent qualities. In recent years, it widely used in machinery, chemical, electricity, metallurgy, etc, especially having good application on the boiler pipeline of thermal power plant, solving effectively the boiler pipeline’s abrasion and corrode at high temperature, playing a great role for running safely and steadily and bringing the power plant economic and social benefit.

     The operating principle of Excellent Supersonic arc spraying technology is: two alloy wires are put into the conductive spouts of arc spraying gun, which connect two high current and low electrodes. When the wires go forward to get touch each other, they shall have a short circuit, they produce arc in which temperature will reach 5000℃.The heads of wires are molten and atomized to micro melted drops and then they shoot to the workpiece at the speed of more than 400m/s (supersonic) by compressing air flow (about twice velocity of sound), then a piece of arc spray painting tier is formed. Compare with ordinary arc coating, Excellent Supersonic arc spraying coating has particularity, higher density and combining strength coating.

      CAS-400 excellent supersonic arc spraying equipment is developed on the basis of CAN-400 arc spraying equipment, increasing acceleration rate air current of Lavalle in the structure of spray gun. When the compression air goes through the Lavalle current, the air’s pace will increase prominent, then it drives atomized particle to realize supersonic spraying.

Characteristics of CAS-400 Excellent Supersonic arc spraying equipment

 

   The excellent supersonic arc spraying equipment (CAS-400) is mainly composed of high frequency inverse pulse power source, supersonic spraying gun, wire delivery machine, controlling system, compressing air system. Superior device, reliable performance, fine off duty stability, the above points would provide essential guarantee for obtaining a superior performance coast of spray coating.

1、performance stabile, simple to handle

     This machine solidifies the function by integrated circuit, the machine carries out norm procedure operation automatically when working, avoiding machine to be damaged because of operator’s mistakes, guaranteeing operator and equipment’s safe. This machine outfits remote switch, under the situation of far to leave the computer, we can even going on spraying work. The output voltage and current of excellent supersonic arc spray equipment is very stabilization, the capability of anti-interference is strong, the power sensitive adjust, carbon burning loss of spraying materials goes down greatly, the coating looks more uniformity, thus it can be used in abominable word conditions for a long time, the using life of the equipment is very long.

2 high combining strength coating :

     The binding strength of spray plaint is up to 70MPa ,and the usual are spraying only achieves 30~40MPa;jet velocity of particles is high, good atomizing, fine power, formative spray plaint presents particularity, higher density(porosity≤0.5%), so the spray plaint’s resistance to wear and corrosion stability become higher.
3、no deforming of work piece、no infection to the structure of the work piece :
      No deforming of work piece because of the spraying temperature is under 100℃, spraying heat dose not acting on the surface of work piece directly, there is no infection to the structure of the work piece either.

4、higher spraying efficiency、wider suitable:
     Higher spraying and source using efficiency, spraying alloy wires 40Kg each hour. Wider suitable for many kinds of metal wires and ceramic materials(solid wires and pulverous wires):alloy wires ,Mo, Al, Zn, Cu, copper alloy, Babbitt metal etc, the anti chafe and antisepsis spray technology is used widely in power plant, such an water screen tube, superheater tube,  economizer tube of the boiler, induced-draft fan’s impeller and volute of the milling system, iron-printing machine’s roller, paper machine’s dryer, axletrees, pumps, valves, dies, chemical metallurgy equipments and parts.
5、spray gun’s range extending is great、available to pushing and giving the silk:
     Spray gun mixes 30m cable, air cover manages and 8core controlling cable, the radius of activities scope which spray gun to the computer reaches 30m, so it can spray spot position of remote. There are two ways of the machine giving silk: drawing silk and pushing silk.  
6、the wearing parts need not to instead regularly:
     Patent designed Limbs as conductive spout could be used for a long time, thus it will improve the using time of wearing parts, work efficiency, and it’s also useful to advance the spray coating’s quality.

7、maintenance is convenient :
   Considering maintain of the computer and the spray gun’s structures, we adopt an idea of compact structure and opening、putting simple.
