SRY6-9 Tubular Heating Element
Fluid explosion-proof electric heater is a device that converts electrical energy into thermal energy to heat the material to be heated. During operation, the low-temperature fluid medium enters the inlet through the pipeline under pressure, flows along the specific heat exchange channel inside the electric heating container, and uses the path designed based on fluid thermodynamics to take away the high-temperature thermal energy generated by the electric heating element during operation, thereby raising the temperature of the heated medium. The outlet of the electric heater obtains the high-temperature medium required by the process. The internal control system of the electric heater automatically adjusts the output power of the electric heater based on the signal from the temperature sensor at the outlet, so that the temperature of the medium at the outlet is uniform. When the heating element overheats, the independent overheat protection device of the heating element immediately cuts off the heating power supply to prevent the heated material from overheating, causing deterioration, coking, carbonization, or even burning out the heating element in severe cases, effectively extending the service life of the electric heater.
1. The working voltage shall not exceed 1.1 times its rated value, and the shell should be effectively grounded.
2. The dimension "B" in the figure must be fully immersed in oil (and regularly checked) to avoid burning out. The heated oil should be free of corrosive gases.
3. The installation hole size of this electric heater is φ65mm.
4. This model of heater is designed according to the JB2379-78 flowing oil standard, with a surface load of 2-3.8 w/cm2.
5. When selecting, the heater size should be determined based on the actual size of the heating medium.
Note: This heater can be directly mixed with SRY2 and SRY4 models.
Generally speaking, we can divide immersion tubular electric heaters into six categories: finned electric heating tube heater, flange electric heating tube heater, titanium electric heating tube heater, Teflon electric heating tube heater, quartz heating tube heater, and radiant electric heating tube heater.
SRY6-9 Tubular Heating Element
Small size, high power: The heater mainly uses clustered tubular electric heating elements. Fast thermal response, high temperature control accuracy, and high overall thermal efficiency. High heating temperature: The maximum working temperature of the heater design can reach 850°C. The medium outlet temperature is uniform, and the temperature control accuracy is high. Wide application range and strong adaptability: This heater can be used in explosion-proof or ordinary places, with explosion-proof grades up to dⅡB and C, and pressure resistance up to 20MPa. Long life and high reliability: This heater is made of special electric heating materials, with low design surface power load and multiple protections, greatly improving the safety and service life of the electric heater. Fully automatic control: According to requirements, through the heater circuit design, it can easily achieve automatic control of parameters such as outlet temperature, flow rate, and pressure, and can be networked with computers. Significant energy-saving effect: Almost 100% of the electrical energy generated is transferred to the heating medium.
