What are the common troubleshooting methods for explosion-proof electric heaters?

Explosion-proof electric heater as internal explosion-proof structure and advanced equipment, electrical energy is converted into heat energy to heat conduction oil as heat carrier as heat transfer medium, using high temperature oil pump forced liquid circulation system, in this way, the continuous transfer of heat; meet a device for high precision control mild heating process requirements. The explosion-proof electric heater's volume is not large, but its power is great. The rated power of a single heating pipe can do more than 6000W, can be easily made plate electric heater, electric heater, gas heater, oven, oven and other high infrared electric heating equipment.

The temperature sensor of the electric heater will be communicated to the controller output signal within the system, and can automatically adjust the output power of the heater, so that output medium temperature is more uniform; there are some dust and gas is inevitable in the surrounding environment, in case of leakage of easily explosive hazards, so overheating protection device of explosion-proof electric heater in the heating element temperature immediately cut off the power supply, effectively protect the safety of personal property.

Explosion-proof electric heater is a kind of electric energy conversion to heat energy, to heat the heating material. The electric heater internal control system according to the automatic regulation of the heater power output temperature sensor signal output port, the output port of the uniform medium temperature; when the heating element overheating, overheating protection device independent of the heating element immediately cut off the heating power, heating the material to avoid overheating caused by coking, metamorphism, carbonization, leading to severe fever element burn, prolong the service life of the electric heater.

Fault treatment of explosion-proof electric heater:

Use the multimeter to measure whether the main circuit power is normal and check whether the power supply is sent out.

Open the voltage regulation module to check the module circuit board is normal, change the voltage regulation module and replace the fuse.

Using the multimeter DC voltage file to measure whether the relay coil has direct current, if no electricity is indicated, the constant closed point is not closed, and the instrument is notified to check the instrument.

When the fault alarm relay acts, the fault alarm lamp will be lit, and there will be a sound alarm. If the overheated temperature controller overheat the alarm, it should stop the electric heater, and then use it after the temperature drops, and further check the related equipment. If the internal fault alarm of the voltage regulating module is usually caused by the burn out of the electronic components, the same type of pressure regulating module spare parts should be replaced as soon as possible, so as to ensure the production needs. If the medium temperature measuring device fails to alarm, we should check the change of the field temperature probe.

When the voltage regulating module not receiving the control signal, should use special clamp meter to measure the current signal measurement, or the voltage regulating module removed any line, the multimeter in current gear is connected in series between the two lines, to see if there is a current signal sent over, if not inform the staff with the inspection instrument.
