Several maintenance methods for thermal oil heaters

Regardless of the type of equipment, maintenance and upkeep are very important tasks. Ruiyuan Heating Equipment Engineers have summarized the following maintenance methods:

(1) The electrical control cabinet should be kept free of dust and should be frequently purged with compressed air to ensure good electrical contact.

(2) The thermal oil in the electric heating thermal oil boiler should not exceed the allowable temperature. To ensure the quality of the thermal oil, the performance indicators of the organic heat carrier should be strictly controlled. When the organic heat carrier furnace is started for the first time, the exhaust valve should be opened to clear the air, water and organic heat carrier mixed steam in the electric heating thermal oil boiler. Generally, after six months of use, the thermal oil should be sampled and tested every 3 to 6 months, and be careful not to mix different oils.

(3) The temperature measuring instrument of the electric heating thermal oil boiler should be checked frequently and measured regularly to prevent the increase of thermal resistance of the temperature measuring node, resulting in inaccurate temperature and misoperation.

(4) The installation of the circulation pipeline should facilitate the removal of gas in the pipe. If there is a leak in the circulation pipeline, it should be stopped in time and repaired before use.

(5) If the oil temperature of the electric heating thermal oil boiler is difficult to rise during operation, the user should immediately check whether the pipeline is unobstructed, whether the valve is wrong, and whether the filter is blocked. The problem should be eliminated before use. The filter should be regularly disassembled and cleaned. (6) The user should customize detailed operating procedures and regular maintenance and repair system. The operator of the thermal oil electric heater should be very familiar with and master the operating principles of this equipment. (7) The electric heating pipe contacts, fuses, instruments, electric contact pressure gauges and relays should be checked regularly. (8) Since the electric heating thermal oil boiler uses instruments, violent vibration is strictly prohibited during transportation and installation. Proper maintenance and maintenance of the electric heating thermal oil boiler can extend the life of the equipment, maximize its working efficiency, and ensure safe and stable operation of the entire production process. (9) After long-term use, the user must ensure that the wiring is reliable after replacing the electric heating element, and the heater must be tested for leaks to prevent thermal oil leakage, poor contact of the wires, and ignition from causing fire accidents.
