Troubleshooting methods for heaters

When the set temperature is reached, the heater enters a constant temperature state. The electric vehicle battery heater uses the thermal energy generated by the auxiliary heater to heat the battery pack, which does not consume battery power and therefore does not affect the power and range of the electric vehicle. At the same time, it can also ensure the heat required by the air conditioning system. The vehicle controller distributes heat by controlling the opening of each electronic control valve, and the control method is simple. The process control during the use of the insulation cover and its impact on the precision rolling process were analyzed. By statistically analyzing, categorizing, and organizing the on-site measured data of the hot rolling production line, the main reasons for the temperature drop of the strip on the intermediate roller conveyor were analyzed. The oil drum heating belt adopts the soft and bendable characteristics of a silicone heating plate. Metal buckles are riveted on both sides of the heating plate with reserved holes, and spring buckles are used to fasten to the barrel, pipeline, and tank body. Easy and fast installation. It can make the silicone rubber heating plate use the tension of the spring to tightly adhere to the heated part, heating quickly and with high thermal efficiency. During the heating process, the overheat temperature controller detects the internal temperature of the heater through the heating element and sends the internal temperature signal of the equipment to the control system through nodes. Thermal distance is used to measure and display the temperature of the medium, providing power for temperature signal equipment. At the same time, the measured medium temperature signal is sent to the control system, which compares the medium temperature with the thermal element temperature calculation, and automatically sends a control signal to the control module to control the output power of the heater. When a lithium battery heater malfunctions during operation, it should be quickly inspected, analyzed, and dealt with, otherwise the medium temperature and catalyst activity will affect the quality of the polymerization product. Let me briefly explain some common troubleshooting methods.

Troubleshooting method:

1) Use a multimeter to measure whether the main circuit power supply is normal and check if the power supply is working properly.

2) Open the voltage regulation module, check if the module circuit board is working properly, replace the voltage regulation module and replace the fuse.

3) Use a multimeter to test whether the relay coil has DC power supply in the DC voltage range. If there is no electricity, it indicates that the emergency stop normally closed point has not been closed. Notify the instrument to cooperate with the inspection.

4) When the fault alarm relay is activated, the fault alarm light will light up, and we also have a sound alarm. If the temperature is too high, the instrument can control the overheating alarm. The lithium battery heater should be stopped in time until the temperature continues to decrease before use and further inspection of relevant enterprise equipment should be carried out. If the internal network fault alarm of the voltage regulation module is usually caused by the burning of electronic components, it should be replaced with spare parts of the same model as soon as possible to ensure safe production and daily needs. If the medium temperature measurement device malfunctions and alarms, the actual temperature probe on site should be replaced according to the inspection.

5) When the voltage regulation module does not receive the internal control system signal, a specialized clamp ammeter should be used to measure the working current through the signal for analysis and measurement technology, or any larger wire should be removed from the voltage regulation module. The multimeter should be connected in series between the current range to see if there is a current signal sent. If we do not have it, notify the instrument management personnel to cooperate with the inspection.

6) Use a shaker to remove the three-phase power supply from the body of the lithium-ion battery heater to measure whether the internal insulation resistance of the lithium-ion battery heater is normal, and use an instrument to measure whether the internal resistance value of the lithium-ion battery heater is balanced. If the resistance is balanced, the lithium battery heater is not disconnected internally. Barrel heater
