Electric Thermal Oil Heater require regular maintenance to ensure safe operation and extend their service life.
First, regularly check the condition of the thermal oil. After prolonged use, the thermal oil may deteriorate or carbonize, affecting heat transfer efficiency. It is generally recommended to take samples for testing every six months. If the viscosity increases or impurity levels rise, the oil should be replaced promptly.
Secondly, clean the heating tubes and pipes. Over time, the surface of the heating tubes is prone to coking, which reduces heating efficiency. Special cleaning agents can be used for regular treatment to keep the pipelines unobstructed.
Additionally, inspect the electrical system. Check for wire aging, loose terminals, and the accuracy of the temperature control instrument. Problems with these components may pose safety hazards.
Finally, pay attention to the maintenance of pumps and valves. The circulation pump should be lubricated regularly, and the valve should be tested for smooth switching to prevent jamming.
In general, Electric Thermal Oil Heater require regular checks of the thermal oil, cleaning of the pipes, and maintenance of the electrical system and mechanical components. Only by performing these tasks properly can the equipment operate stably and avoid unexpected downtime.
