1. Cleaning inspection: Regularly clean the dust, debris and oil on the surface of the heating device, and check whether the heating elements, gas pipelines, wires, etc. are damaged, aged or loose.
2. Gas system maintenance: For gas heating devices, check whether there are leaks at the gas valves and pipeline connections, and regularly clean the gas filter to ensure that the gas supply is normal and pure.
3. Electrical system inspection: For electric heating devices, check whether the wire insulation is good, whether there are signs of damage or short circuit, and whether the plug and socket are firmly connected.
4. Temperature sensor calibration: Regularly calibrate the temperature sensor to ensure the accuracy of temperature display and control.
5. Heating element maintenance: Check whether the resistance value of the electric heating element is normal, whether the nozzle of the gas burner is blocked, and replace or clean it in time if there is any problem.
6. Lubrication of moving parts: Lubricate the moving parts in the heating device, such as the valve shaft, to ensure its flexible operation.
7. Preheating before operation: Before each use, turn on the heating device in advance for preheating according to the prescribed time to check whether its working condition is normal.
8. Regular testing: Test the heating effect regularly to ensure that the specified temperature and uniformity can be achieved.
9. Storage protection: When the equipment is idle, protective measures should be taken to prevent the heating device from being affected by adverse factors such as impact and moisture.
