How to maintain the temperature controller of large blow molding machine

The temperature controller of large scale blow molding machine is a part of the die head energy storage heating system. 

Heating and temperature control system for large extrusion blow molding machine

In recent years, some changes have taken place in the heating system of large blow molding machine. PLC temperature module is used instead of temperature controller, and solid state relay is used instead of contactor. But the heating equipment changes little, this technology update and improvement provides convenience for the integration of electronic control system, reduce the connection of electronic control system and components. Adopt electric control technology, completely use temperature electric control system to replace the existing temperature control system.

Maintenance of temperature controller of large blow molding machine

Special attention: Use downtime to clean instruments and keep them clean.

1) Ensure that the temperature controller is securely connected to prevent the connection and connection points from affecting the normal operation.

2) Check whether the wiring of the temperature sensor is firm.

3) In hot weather, pay attention to ensure that the ambient temperature of the temperature controller is within the normal operating temperature range. When the ambient temperature is too high, effective cooling measures should be taken.

4) Under wet conditions, if the equipment is in the stopped state, power should be supplied to the temperature instrument regularly to prevent the failure of the instrument due to moisture. After a long shutdown, carefully check and power on for 4-6 hours, then start running.

5) Replace the deactivated temperature controller and temperature sensor in time. Check whether the model and voltage of the temperature controller are consistent with the temperature control range, and whether the cable connections are correct.
