Embodiment Construction
[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0022] 1. First, turn on the switch cabinet 2 and the compensation cabinet 1 first, turn on the ion water cooling device 15 on the thermal spray molding device 6, and keep the circulating water pressure of the ion water at about 0.2Mpa, and keep it open. Operation console 9 sends electricity;
[0023] 2. Open the high and low cylinder oil level regulating valve on the vacuum pump 7 for 5 minutes, then close the vacuum pump 7 and the ion water cooling device 3, and adjust the position of the thermal spray heat shield 17 to 12mm from the upper opening of the water cooling jacket;
[0024] 3. Adjust the motor rotating device 11 so that the rotating speed is 85 rpm, adjust the arc welding transformer current of the cluster electrode rod 14 to 1400A,...
