The following precautions should be taken when operating
portable generators in low-temperature environments:
1. Choose a generator model suitable for low-temperature environments: When purchasing a generator, attention should be paid to its applicable operating temperature range and choose a model that can operate normally in low-temperature environments. Some generators have low-temperature starting devices and antifreeze lubrication systems, which can better cope with low-temperature environments.
2. Preheat the generator in advance: In low-temperature environments, the body and components of the generator may become stiff, so preheating should be carried out before starting to ensure that the body and components reach the appropriate working temperature.
3. Use low-temperature lubricating oil: Traditional lubricating oil may solidify at low temperatures and cannot lubricate generator components properly. Therefore, it is necessary to choose low-temperature lubricating oil suitable for low-temperature environments to ensure the normal operation of generator components.
4. Prevent generator icing: In extreme low temperature environments, the casing and components of the generator may freeze, affecting normal operation. Anti freezing measures need to be taken, such as heating insulation or using anti freezing lubricants.
5. Regularly check the cooling system: In low-temperature environments, the cooling system of the generator may be affected by icing and other issues, resulting in poor heat dissipation. It is necessary to regularly check the cooling system to ensure that it is unobstructed.
6. Pay attention to body insulation: Low temperatures in winter can easily cause excessive cooling of diesel engines, especially in northern regions, where insulation sleeves and curtains should be equipped with cold proof devices.
7. Low speed preheating: After starting the generator set, it should be run at low speed for 3-5 minutes to increase the overall temperature. Then, check the working condition of the lubricating oil, conduct a comprehensive inspection of all switches, power supplies, and valves to ensure normal use before putting it into operation.
8. Check the starting lead-acid battery: In areas with sustained severe cold, a comprehensive inspection of the starting lead-acid battery is also necessary.
By implementing the above measures, it is possible to ensure the normal operation of portable generators in low-temperature environments and extend their service life.
