Introduction of overheat protection device for heat conducting oil electric heater

Now, the majority of thermal oil heater basic lack of awareness and understanding, the quality of thermal oil heater is not recognized, always to the manufacturing industry and the manufacturing industry of second-hand remanufacturing industry confused, expectations are not high. Therefore, the concept of remanufacturing industry is not in the hearts of people, related manufacturing enterprises and even many of the same industry are absolutely ignorant of in the manufacturing industry, caused the people to understand the manufacturing error. In fact, the boiler has considerable development space and broad market prospect in the manufacturing industry.

Different types of heat conduction oil heater, remanufacturing process content is not the same, according to user requirements, different remanufacturing content should also be different. Therefore, the boiler in the manufacturing industry should not only thoroughly understand the original equipment performance structure, but also have a practical understanding of the new requirements of the users, and combine the actual structure, in the transformation design application. Abroad, some advanced equipment manufacturers will take into account the product life cycle again in the product design before, and lay a solid foundation for the renovation of equipment in the future.

In foreign countries, remanufacturing has been developing for decades and has become an important component of recycling. In the process of production equipment, the remanufacturing industry has important influence on both the investment of the production line and the consumption of energy and raw materials. Compared with the manufacture of new products, the remanufacturing equipment has an average of 60% - 70%, which can be recycled. At the same time, 85% of the energy consumption of water and electricity can be saved in the process of production.

According to the survey, China is the world's largest oil heating electric heater consumption market, but also the world's largest machine tool sales. With the development of industry, these heat conducting oil heaters can not meet the needs of the modern market. Therefore, the market potential of heat conductive oil heater is very large.

A heat conducting oil heater is a kind of electric energy that is consumed to be converted into heat energy to heat the material to be heated. In the work of low temperature fluid through a pipe under pressure into the input port, take away heat energy generated by electric heating element in the work of the heating medium temperature along the electric heating container specific heat flow, when the heating element overheating, overheating protection device independent of the heating element immediately cut off the heating power, using the path fluid thermodynamics principle design, thermal oil heater exports have high temperature medium process requirements. Thermal oil heater internal control system based on the automatic regulation of the heater power output temperature sensor signal output port, the output port of the uniform medium temperature; avoid heating material overheating caused by coking, metamorphism, carbonization, leading to severe burn out heating element, prolong the service life of electric heater. In order to ensure the heat-conducting oil furnace system safe and normal operation of equipment, managers should pay attention points.

Operators must undergo rigorous training, the examination qualified, before they can mount guard. Operating personnel mount guard duty, to strictly enforce the technical safety rules and procedure and post responsibility system, discipline, dedication, the abnormal phenomena appeared in the system to deal decisively and promptly report to their superiors. Strictly adhere to the circulating pump starts when driving after ignition, parking to a ceasefire, thermal oil circulation pump continues to run, so the oil temperature to 100 degrees below the sequence of operations to stop the pump, at any time may not reverse the order. For the first time to drive or add new oil, oil must be removed in the water and light components, should pay attention to in the dehydration process of exhaust system, temperature reaches 100 degrees Celsius, slow heating speed, so that the water and light group to share fully vaporized, and repeatedly emptying, temperature and pressure curve when conducting oil with the corresponding relationship between the rear can operate in accordance with the provisions of the heating curve.

It is strictly prohibited to add new heat to the heating system when the equipment is in normal operation. In the system after driving, such as thermal oil circulation system in the inlet and outlet pressure fluctuations, temperature exceeds the limit, the velocity is lower than the set value, the system cannot be put into normal operation, measures should be taken to eliminate the above phenomenon, the indicators of stability in the set range, the whole system can be put into normal operation. To adhere to the duty tour inspection system, the personnel on duty shall be the key parts in the system, such as circulating pump, high tank, liquid level meter, pressure meter, temperature meter, flow meter, bypass filter to timely inspection, promptly eliminate abnormal. In the thermal oil furnace test or inspection, shall be used for low voltage explosion-proof lamp 12V. Emergency measures and plans for dealing with sudden power cuts should be worked out to protect the furnace tubes and heat transfer oil effectively. In case of a sudden power outage of coal-fired thermal oil furnace should open the door, stop heating, wet coal fire pressure or emergency shutdown, removing all the embers, quickly open the cold oil replacement valve oil, but the oil discharge rate can not be too hasty. The cold oil in the high groove is put into the lower trough through the furnace tube, and the oil in the lower groove is circulated into the high groove by hand pump to reduce the temperature of the system. If a standby oil circuit or a generator is provided, the circulating pump is switched on, and the circulation of the heat conducting oil system is resumed. If the fuel oil and gas heat conducting oil heater is suddenly cut off, the fire should be extinguished immediately besides the above measures, and the baffle of the furnace door and the flue will be opened to reduce the furnace temperature.

Every six months, the thermal conductivity of the system oil sampling test, if the acid value, viscosity, lightning and carbon residue four indicators to scrap value. New oil should be replaced in time. When replacing the new oil, the impurity and dirt in the inner wall of the system should be removed so as not to affect the thermal efficiency and service life of the heat conducting oil. After the ignition furnace flameout, 10~15min forced ventilation must be inside the furnace, combustible gas blowing furnace residue.
