Product Description

1. Failure Inspection and Alarm System: 
This production line has complete failure detecting, alarm, diagnose, safety protecting function. Audible alarm will notify operator in time to take action.

Pressure control system has alarm function like : furnace pressure abnormal alarm, gas pressure abnormal alarm , air pressure abnormal alarm, and compressed air low pressure alarm. If one of the data is not met required level, solenoid valve will cut off gas supply.  

For safety operation, combustion system is mounted with many safety valves, such like anti-explosion valve, cut-off valve, shut-off solenoid valves. Once power supply is stopped, solenoid valves and actuator will automatically shut off.

The driving system is with a main drive chain breakage detector.
The hot air circulating fan is with a rotating speed detector and a soft starting device.

2. Manual Operation during commissioning and Maintenance:

During commissioning or maintenance the production line, operator can manually run the equipment through operating box and touchable panel.

3. Touchable Screen
For easy to reflect actual running condition of the production line, and easy for operator to run the equipment, 2 sets of MP277 touchable panels are separately located at loading, and unloading area.
