Plasma Spray Equipment, Powder Coating
Plasma Spray Equipment SX-80
Ultrasonic plasma spray characteristic:
(1),it can spray many kinds of coating material,especial to spray high melting point refractory material,such as refractory metal,ceramic,metal ceramic and other special functional material.
(2), The inert gas can be working medium,which can reduces the flying coating particle’s oxidization .
(3)The coating has high adhesive force,low porosity.It can make fine coating by controlling the technical parameter
Main Components:
(1)SX-80 main power supply
Silicon controlled rectifier, maximum power input: 85KW, arcing time factor: 100%, plus or minus 15% Grid fluctuation, Maximum power output: 80KW. It can work normally under Current fluctuating range: 1~2%. The power supply provides DC current for spray gun. It is controlled by intelligent module, working 24 hours without breakdown. It is the best plasma power supply in China.
(2)SX-80 transfer box
The transfer box is the transfer center of this plasma spraying equipment. It links power supply, control cabinet, heat exchanger and spray gun together. There are high frequency ignition , waterway and gas circuit alarming devices inside this box. The transfer box is moveable, with standard 5 meter long water-cooled cable.It mixes the water and electricity and sends them to the spray gun,meanwhile it offers high frequency impulse voltage which is needed when the spray gun forms the arc,and tests spay gun’s returned water’s temperature and cooled water’s pressure.It’s easy and flexible,easy to draw,is good at forming arc ,and can reduces the moment currency’s impact when the nozzle is forming arc.
(3) SX-80 control cabinet
Control cabinet is the control center of SX-80. Its input voltage and power are single phase 220V, 1Kw. It is equipped with float flowmeter, it’s digital displaying for indicating current and voltage. It has three working modes of manual control, automatic control and economic operation. It’s equipped with alarming and breakdown display unctions. It will alarm when:1). Pressure of main and secondary gas is lower than 0.3Mpa, or main gas flow is under 30L/min.
2). Water temperature is higher than 50, or water flow is under 8L/min.
The control cabinet is used for controlling and adjusting water, electricity, gas and spray powder. It monitors the whole spray system so users can directly get the working parameters of the system, that is to say, you can directly read the voltage, current and so on. When the power supply or gas supply cannot meet the system requirement, there will be automatic alarming warning,which can remind the user to make corresponding adjustment. By operating the control cabinet panel, users can adjust the current and voltage to regulate the temperature of plasma arc. They can also adjust the main and secondary gas to regulate the gas flow and gas proportion for changing the length and velocity of plasma arc
(4)SX-80 powder feeder
The powder feeder is used to store spray powder and send these powder to spray gun according to technological requirements. The SX-80 system is equipped with one binocular powder feeder. The range of powder particle size is 5~200m. The two tube can feed powder at the same time, the feeding speed is 8~250g/min. Users can adjust the potentiometer on control cabinet panel to regulat the feeding speed.
(5) SX-80 spray gun
We can offer customer imitative METCO 9 MB spray gun, using argon or nitrogen as main gas, hydrogen as secondary gas. The working current of spray gun: 100-800A. The working voltage: Ar+H2: 50-75V, N2+H2: 50-80V. We provide the following spray gun accessories for our customer: spray nozzle, powder and cooling air jetting shelf, water-cooled cable, electrode tip, insulator, sealing ring, and other special tools.
(6)SX-80 heating exchanger
Heat exchanger is also called refrigerator or water chiller. We use double motors compressor to make this machine smaller and save space for our customer. The spray gun is cooled down by water, and we use heat exchanger to cool down the high temperature water coming from spray gun, and then use these cooled water to cool down the spray gun again. In this way the spray gun can keep a normal working temperature and prolong the usage life of spray nozzle.
Function characteristic
The range of testing temperature is -4.9℃-94.9℃,dispraying resolution ratio is 0.1℃,controling sensitivity is 0.1℃,offset range is -0.5℃—10℃,used in AC220V input.the instrument use condition:relative humidity less than 90%RH,the temperature is within 0—45℃ with no corrosion and water-proof.
