Hot oil electric heater is a widely used heating equipment, especially in some environments where the accuracy of heating temperature is extremely demanding, it has a wide range of applications. Some reactor equipment manufacturers have begun to use mold temperature equipment to assist in heating or cooling the reaction materials to meet the temperature conditions required by the process.

Inspection and Maintenance of Heat Transfer Oil Electric Heaters

Explain the inspection and maintenance of heat transfer oil electric heater:

1. The daily inspection items of the heat transfer oil electric heater.

1. The heating body of the heat transfer oil electric heater: if the terminal is overheated and damaged, check whether the electric heating element is damaged, decide whether to replace or repair it according to the degree of damage, and check the sealing part of the electric heating element and the welding seam between the sealing part and the tube sheet flange , If there is oil leakage, replace the heating element in time;

2. The pressure gauge of the heat transfer oil electric heater: if the pointer fluctuates, check whether there is undischarged water or gas in the system, and carry out corresponding dehydration and exhaust; if there is oil leakage or air leakage in the gauge, replace it with a new gauge ; High temperature oil pump: If there is vibration or abnormal sound, cavitation may occur, and the oil filter must be cleaned;

3. Expansion tank of heat transfer oil electric heater: When abnormal sound or vibration occurs, check whether the pipeline is blocked;

4. The liquid level gauge of the heat transfer oil electric heater: if the liquid level is too low, it is necessary to add new oil in time;

5. The temperature regulator of the heat transfer oil electric heater: if the temperature rises too fast, too slow or cannot be set, check whether the electric heating element is damaged, whether the system pipeline is blocked, and whether the components in the electric control cabinet are damaged.

6. The pipeline valve of the heat transfer oil electric heater: whether the switch position is correct and whether there is oil leakage.

2. The main purpose of setting the filter is to prevent large solid particles in the pipeline from entering the high-temperature oil pump. When installing, pay attention to checking the filter and do regular cleaning, which can greatly improve the service life of the heat transfer oil and equipment.

3. During normal operation, the oil temperature in the expansion tank should not exceed 70 ℃. If the oil temperature is too high, it means that the system is not running smoothly or the pipeline connection is improper, which is harmful to the service life of the heat transfer oil. into production.

Fourth, the heating body should be checked and tightened frequently
