Operation specification requirements for equipamento de têmpera de alta frequência

1. Os operadores de equipamentos de têmpera de alta frequência devem passar no exame e obter um certificado de operação antes de serem autorizados a operar. O operador deve estar familiarizado com o desempenho e estrutura do equipamento, devendo respeitar o sistema de segurança e turnos;

2. There must be more than two people to operate the high-frequency quenching equipment, and the person in charge of the operation must be designated;

3. When operating the high-frequency quenching equipment, check whether the protective shield is in good condition, and idle people are not allowed to enter during work to avoid danger;

4. Before working, check whether the contact of each part of the equipment is reliable, whether the quenching machine tool is running well, and whether the mechanical or hydraulic transmission is normal;

5. When preparing to turn on the water pump during work, check whether the cooling water pipes are smooth and whether the water pressure is between 1.2kg-2kg. Be careful not to touch the cooling water of the equipment with your hands;

6. The power transmission preheating is performed at the first stage, the filament is preheated for 30min-45min, and then the second stage is performed, and the filament is preheated for 15min. Close and continue to adjust the phase shifter to high voltage. After adding high frequency, hands are not allowed to touch the busbars and inductors;

7. Install the sensor, turn on the cooling water, and drain the workpiece before the sensor can be energized and heated, and no-load power transmission is strictly prohibited. When replacing the workpiece, the high frequency must be stopped. If the high frequency cannot be stopped, the high voltage should be cut off immediately or the emergency switch should be connected;

8. During the operation of the high-frequency quenching equipment, it should be noted that the positive flow and the powder flow are not allowed to exceed the specified value;

9. When working, all the doors should be closed. After the high voltage is closed, do not move to the back of the machine at will, and it is strictly forbidden to open the door;

10. Se forem encontrados fenômenos anormais no processo de trabalho do equipamento de têmpera de alta frequência, a alta tensão deve ser cortada primeiro e, em seguida, as falhas devem ser analisadas e eliminadas.

11. A sala deve estar equipada com equipamento de ventilação para remover os gases de combustão e gases residuais emitidos durante a têmpera e proteger o meio ambiente. A temperatura interna deve ser controlada em 15-35°C.

12. Depois de trabalhar, primeiro desconecte a tensão do ânodo, depois corte a fonte de alimentação do filamento e continue fornecendo água por 15min-25min, para que o tubo eletrônico esteja totalmente resfriado e, em seguida, limpe e verifique o equipamento, mantenha-o limpo e seco para evitar que os componentes elétricos descarreguem e quebrem. Ao abrir a porta para limpeza, descarregue primeiro o ânodo, grade, capacitor, etc.
