Aluminum oxide-Plasma spray has become an indispensable way of processing in the fields of modern industries, national defenses, and science and technology. All kinds of metal, alloy, ceramic, and cermet can be used through plasma spray to make good wearable, anti-corrosive, high-temperature-resistant, high-temperature-oxidation-resistant, conducting or insulated, far infrared radiation coating. Plasma spray is an effective way for the work piece to gain good working performance, prolong its useful life, improve quality, and save precious metal material. Configuration of Aluminum oxide-plasma spray equipment SX-80 absorbs the experiences of PT-A3000 and METCO-9M plasma spray equipment and its performance level is equivalent to METCO-9M. It mainly consists of main electricity supply, control cabinet, transfer box, powder feeder, spray gun and heat exchanger. Main power supply silicon controlled rectifier, biggest input power 105kw, duty cycle 100%, biggest output power 80kw, electric current fluctuation range ±1-2%,when electric grid fluctuation is within ±15%, it can normally work. Transfer box It’s the transfer center of spray equipment which connects power supply, control cabinet, heat exchanger and spray gun together. It has high-frequency ignition, waterway and gas circuit alarm equipment insides. The box can be moved freely and the standard length of cable is 5m. Control cabinet It’s the control center of the whole spray equipment. Single-phase 220V, 1KW, float flowmeter equipped, current and voltage digisplay.  Having manual, automatic and economic working modes. Alarm and malfunction indicating function, generally it alarms under such conditions: when the main and assistant gas pressure<0.3MPa or the main gas flow rate<30L/min when water temperature>50°C or water flow rate<8L/min Powder feeder  Supply one set of two-tubed powder feeder  powder measurement scope: 5-200μm;powder repeated-feeding error rate<±1%  The two tubes can feed powder at the same time, feeding rate is between 20-150g/min. Spray gun Supply imitative METCO 9MB spray gun, main working gas is argon or nitrogen, assistant gas is hydrogen. Working electric current: 100-800A. Working voltage: Ar+H2: 50-75V, N2+H2: 50-80V 1. Imitative 9MB machine-made gun 2. Imitative 9MB manual-made gun 3. Large-inner-hole spray gun Supply spray gun accessories: GH,G,GP,GE type spray mouth, powder feeding and cooling air jetting-shelf, water cooled cable, electrode tip, insulator, obturating ring, special purpose tools. Also we can supply customer imitative F4 spray gun (machine-made or manual-made) and accessories such as water cooled cable, spray mouth, electrode tip, powder feeding shelf, powder feeding mouth, obturating ring and special purpose tools. Heat exchanger We provide two kinds of heat exchangers: (1), water pumping heat exchanger has interior and exterior circulation. The interior circulation cools down the spray gun by distilled water, while the exterior circulation cools down the distilled water by tap water. We use imported water pump and below is the parameter of this heat exchanger:        the cooling capacity 20000kcal/h power 8KW Pump pressure 0.8MPa Water flow 8-20L/min Water temperature regulating scope 20-38℃ (2), Freon- refrigerated heat exchanger consists of imported compressor, water pump, and heat exchanger.       the cooling capacity 25000kcal/h power 13KW Pump pressure 0.8MPa Water flow 8-20L/min Water temperature regulating scope 10-28℃
