Operation of high frequency quenching equipment

Операция по высокочастотное закалочное оборудование:

1. Start the equipment and follow the operating procedures.

2. Adjust the electrical parameters. The purpose is to make the high-frequency power supply work in a resonant state, so that the device can play a higher efficiency. Adjust the electrical parameters according to the craft card, or put the coupling handwheel and the feedback handwheel in the middle position and send high voltage. First send half-wave, adjust the sliding transformer to gradually increase to full-wave, the value of anode voltage V is generally 11 ~ 13 kV, up to 13.5kV. The anode current I is regulated by the coupling handwheel, and the grid current I grid is regulated by the feedback handwheel. At the same time, the ratio of I anode to I gate is kept at a specified value. If the ratio is wrong, the coupling handwheel and the feedback handwheel can be adjusted repeatedly until the tank voltage remains unchanged. This shows that the ratio of I anode to I grid has been adjusted and a large output power has been obtained.
