The principle of plasma generator? Where can it be applied?
A plasma generator is a device used to generate high-temperature plasma arcs, mainly composed of three parts: anode, cathode, and coil components. The anode and cathode components include two electrodes used to form an arc, the anode and the cathode. A stable high current (280-350A) is applied between the two electrodes. When the cathode moves forward and comes into contact with the anode, the cathode gradually moves away from the anode and discharges the arc, ionizing the compressed air between the electrodes to form a high-temperature plasma.
A tubular plasma spray gun (parallel flow plasma spray gun) is a device that introduces air into the rotating chamber of a heater in a tangential direction. The airflow rotates at high speed inside the heater, forming an airflow with a radial pressure gradient that flows forward. This airflow can control the arc near the central axis of the heater and elongate it. The direction of forward movement of the airflow is consistent with the direction of the arc axis and is basically parallel to each other. Therefore, the airflow is heated by the arc for a longer time. Due to the increase in arc length, the arc voltage also increases significantly. Under the same power conditions, the arc current decreases correspondingly, thereby improving the service life of the electrode
