Enerjiyə necə qənaət etmək olar yüksək tezlikli söndürmə avadanlığı

1) Select the frequency, power and type of high-frequency quenching equipment. The frequency should meet the principle of penetrating heating, the power should meet the principle of short heating cycle and less heat conduction loss, the type of equipment should be selected with high frequency conversion efficiency, and the power should meet the principle of short heating cycle and less heat conduction loss. high efficiency. The efficiency of important accessories such as quenching transformers is also considered. For example, the frequency conversion efficiency of solid-state power supply is higher than that of high-frequency power supply of electronic tube. It can also meet the technical conditions of the product, and solid-state power supply should be used as much as possible. In solid-state power supply, transistor power supply is more efficient than thyristor power supply, so IGBT or MOSFET power supply should be preferred. The efficiency and water consumption of different types of quenching transformers are also very different, so attention should be paid to the selection.

2) The working specification of high frequency quenching equipment must be appropriate. Improper adjustment of the high-frequency power supply load of the electronic tube, such as inappropriate anode current and grid current ratio, especially in the under-voltage state, the anode loss of the oscillator tube is large, and the heating efficiency is reduced, which should be avoided. When debugging the power supply, make the power factor around 0.9.

3) The requirements for quenching machine tools are: high load factor and short idling time. If multi-axis and multi-station heating can be used at the same time, multi-axis and multi-station structure are preferred. Taking mass production of half-shaft parts as an example, one-time heating is more energy-efficient than scanning quenching.

4) The efficiency of the sensor has a great relationship with the design. The efficiency of the good sensor is above 80%, and the efficiency of the bad sensor is below 30%. Therefore, it is necessary to design and manufacture the sensor well, and continuously optimize it in the production process.

5) Self-tempering or induction tempering should be preferred for the tempering of induction hardened parts.
