SX-80超声波等离子喷涂设备介绍

1、程序：等离子喷雾工作时，阴极和阳极（喷嘴）之间形成直接电弧，该电弧加热工作气体电离成高温等离子体，然后等离子体从喷嘴喷出形成等离子火焰。粉末通过粉末进料气体输送到火焰中，然后熔化、加速，然后喷涂在基材上形成涂层。工作气体可以是氩气、氮气，也可以是与氢气混合，也可以是氩气和氦气的混合气体。

超声波等离子喷雾特点：

（1）、可喷涂多种涂层材料，特别是喷涂高熔点耐火材料，如耐火金属、陶瓷、金属陶瓷等特殊功能材料。

（2）、惰性气体可以作为工作介质，可以减少飞溅涂层颗粒的氧化。

(3)涂层粘接力高，孔隙率低。通过控制技术参数，可进行精细涂装

SX-80等离子喷涂设备的配置

SX-80吸收了PT-A3000和METCO-9M等离子喷涂设备的经验，其性能与METCO-9M相当。主要由主电源、控制柜、转运箱、送粉机、喷枪和换热器组成。

3,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.

4,SG100 spray gun

We can offer customer SG100 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.

5,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.

6,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

7, SX-80 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.

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.
