SX-60 ultrasonic plasma spraying equipment

Product Details

Introduction of SX-60 ultrasonic plasma spraying equipment

1,procedure :when the plasma spray is working,there is a direct electricity arc which is formed  between the cathode and anode(nozzle’s ),this electricity arc heats the working gas to ionize into high temperature plasma, then the plasma is sprayed from the nozzle  to form plasma flame.The powder is delivered to the flame by the powder feeding gas,then it's  melted,accelerated,then sprayed on the substrate to form a coating.The working gas can be argon,nitrogen, or mixed with hydrogen,or argon and helium’s mixture gas.

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

Configuration of SX-60 plasma spraying equipment

SX-60 absorbs the experiences of PT-A3000 and METCO-9M plasma spray equipment and its performance is equivalent to METCO-9M. It mainly consists of main power supply, control cabinet, transfer box, powder feeder, spray gun and heat exchanger.

The following is a picture of the whole system:

 

1,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.

2、SX-60 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.

5,intelligent powder feeder

1、PLC and touch screen are used to set parameters to precisely control powder feeding accuracy and speed.

2、The system consists of two sets of independent powder feeding devices. The capacity of the large tank is 20 liters, and the speed of the scraper-type powder feeding is 150 g/min. The small tank adopts the drum-type powder feeding device, which is suitable for feeding various ultra-fine powder and hard-to-deliver powder mixtures.

3、Fully enclosed plastic-steel chassis, free from environmental disturbance such as temperature and humidity, transparent glass door, powder feeding state at a glance.

Powder vibration device, powder tank heating device and weighing device can be selected

 

6, SX-60 water chiller

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.
