How to emergency stop?
In case of emergency shutdown, there is no need to unload first. You can directly press the "Emergency Stop" button.
After shutdown, the remaining air in the system should be discharged and the pressure should be reset to zero after the air compressor has finished working. After a period of shutdown, the condensate water in the oil and gas drum, oil cooler, and aftercooler should be discharged. If it is cold in winter, it should be avoided to freeze crack, damage, and rust in a low-temperature environment.
Emergency stop record inspection
After an emergency shutdown, it is recommended that you keep a written record of the reason for the shutdown for maintenance and inspection, including:
1. Downtime and type of downtime;
2. Preliminary assessment of emergency shutdown losses;
3. Preliminary Cause Analysis of Emergency Shutdown Accidents
4. Matters requiring assistance from relevant departments for rescue and rescue:
5. Recovery or repair time;
How to reset the emergency stop?
How to reset the air compressor after emergency shutdown?
