The maintenance and upkeep of Longmen CNC cutting machine mainly start from the following four aspects:

Pneumatic system

Pressure reducing valve

Cutting the mouth

Tempering preventer.
　　
1. Maintenance of pneumatic system
a. Regularly wipe and remove dust and debris from the air path to prevent premature aging of the air path.
b. Regularly inspect the air system and promptly address any leaks or malfunctioning components to ensure smooth air flow.
　　
2. Maintenance of pressure reducing valve. Adjust the pressure regulator and adjust the pressure gauge to the required pressure. During the adjustment process, the pressure should be increased from small to large to ensure that the pressure regulator can continuously adjust. If continuous regulation cannot be guaranteed or if gas leaks from the safety valve, a new pressure regulator must be replaced.
　　
3. Repair of Torch Cutting Mouth Tempering Preventer
a. The cutting torch must be a machine cutting torch produced by a professional manufacturer
b. The cutting torch must also use a standard quick cutting nozzle produced by a professional manufacturer. For new cutting nozzles, they must be inspected and qualified before use.
c. If the cutting nozzle is contaminated, special tools are needed to clean the preheating flame hole and cut the oxygen channel.
　　
4. The flashback preventer is an important component for ensuring safety. According to the requirements of the safety department, it is strictly prohibited to disassemble the flashback preventer without authorization. Therefore, if the tempering preventer is used for a long time and cannot meet the gas flow requirements or leaks, it must be replaced by a professional.
