Purpose.
Plasma ignition apparatus form is single in the market, there is following several shortcomings：
1. the life-span is relatively low, the plasma ignition device electrode life deficiency mainly used on domestic market is external similar
The half of product.
2. dielectric gas parameter is substantially stationary under arc plasma gun equipment running status, so electric arc ablation always
Fixed place, causes the life-span to reduce caused by it, and according to statistics, the electrode of majority damage is drawn by the serious ablation in single somewhere
Rise.
3. power adjustable narrow range, adaptability do not reach desired value.
The content of the invention
Present invention aim to provide a kind of adjustable Constant Direct Current source of the voltage with realizing automatic regulation of gas device etc. from
Sub- lance driving device, by automatically adjusting for arc plasma gun equipment medium gas parameter, magnitude of voltage is set constantly to change；Together
When constantly change due to dielectric gas, the position that electric arc is produced in device is also constantly changing, the ablation one for avoiding electric arc from fixing
Individual place, so as to extend the life-span of electrode.
The present invention realizing automatic regulation of gas plasma gun equipment, including plasma gun, plasma gun power supply, negative electrode with
Anode circulation cooling water system, realizing automatic regulation of gas device, the realizing automatic regulation of gas device include valve, main control unit and brushless electric machine,
The valve is installed on the gas pipeline between connection plasma generator dielectric gas compressed air source and the ion spray gun
On, the main control unit controls the brushless electric machine to drive the valve to be converted between the 40% to 100% of valve opening.
It is preferred that the realizing automatic regulation of gas device also includes feedback unit, for feeding back the aperture of the valve.
The adjusting method of the plasma gun equipment of the present invention includes：Step 1: pass through main control unit and feedback unit pair
0%, the 40% of valve opening and 100% tests；Step 2: main control unit control brushless electric machine drives the valve opening
Enter line translation.
It is preferred that in the step 2, valve opening is reached 100% first, brushless electric machine is then controlled by main control unit
The valve is driven using 2% decrease of speed of every five seconds for example valve opening until aperture is 40%；Then with every five seconds for example valve opening
2% speed increase to 100%, repeat the step untill fulfiling assignment.
The advantage of the invention is that：Dielectric gas parameter cyclic changes under arc plasma gun equipment running status,
So place is not fixed caused by electric arc, will not fix only to producing ablation at one, so as to greatly increase the life-span of electrode,
In terms of current effect, using the lance driving device after realizing automatic regulation of gas device, the life-span of electrode increases；Voltage change simultaneously, and
Electric current is constant, and the power of such lance driving device can be adjusted, and adaptability greatly increases.
