The maintenance of Weifang generator set in low temperature winter is very important. The following are specific precautions. I hope the following introduction can provide users with reference.
1、 Maintenance of cooling system for Weifang generator set
Add antifreeze: When the temperature is too low, the water will freeze and may damage the cooling water tank. Therefore, antifreeze should be added to maintain and increase the ambient temperature to avoid liquid freezing affecting the operation of the generator. At the same time, during use, it is necessary to add antifreeze in a timely manner as water is consumed to maintain a sufficient amount.
Water release operation: If antifreeze is not used, the diesel generator should not be drained too early before turning off. It should be run at idle speed until the cooling water temperature drops below 60 ℃ and the water is not hot to the touch before turning off the engine and draining. When draining water, the stored water in the body should be drained to prevent it from freezing and expanding, causing the body to swell and crack. After operation, it is also necessary to promptly drain the water in the diesel engine water tank.
2、 Maintenance of lubrication system for Weifang generator set
Replace lubricating oil: If the indoor temperature is below 0 ℃, the viscosity of lubricating oil suitable for use in other seasons will increase, which is not conducive to the lubrication of internal components and affects engine start-up. Therefore, it should be replaced with low viscosity lubricating oil.
Lubricating oil replacement steps:
Place a flat plate under the lubricating oil drain port of the diesel engine, use a wrench to remove the screw rod, and slowly drain the lubricating oil.
By checking the lubricating oil dipstick, confirm whether the lubricating oil has been completely drained. During each inspection, it is necessary to wipe the dipstick clean for easy observation.
Tighten the screw rod of the oil drain port and slowly inject low viscosity lubricating oil into the lubricating oil tank through a funnel. At the same time, observe whether it meets the requirements through the scale of the lubricating oil dipstick. Inject the lubricating oil to the middle scale.
3、 Maintenance of fuel system for Weifang generator set
Choose diesel with appropriate viscosity: In winter, when the temperature is low, diesel with diluted viscosity should be selected to reduce the impact of temperature on the normal operation of the generator. You can choose -10 # oil or lower grade oil. If there is residual oil in the diesel engine, the oil valve should be removed to drain the remaining oil.
Preheating operation: When the temperature is below 5 ℃, hot water or steam should be added to preheat the engine before starting. Inject clean water at around 70 ℃ into the diesel engine water tank and wait for it to preheat to above 3040 ℃ before starting. At the same time, listen for any abnormal sounds from the diesel engine. For Weifang diesel generators, no-load preheating should be carried out before starting. After preheating for about 35 minutes, the temperature of the generator will be increased. Check if it can operate normally before entering normal operation for power generation.
4、 Fire prevention and electrical safety
Maintenance of Fire Cap: Due to the dry winter weather, in order to prevent diesel engine smoke from igniting flammable or combustible materials in the surrounding area, it is necessary to check the switch of the fire cap and keep it in a daily closed state.
Electrical use: Considering the performance impact and unstable power generation of the generator set, only necessary electrical equipment should be retained when using the generator set, and high-power electrical equipment such as air conditioning and water pumps should be avoided from being turned on to avoid equipment burnout or damage to the generator set due to excessive load.
5、 Other precautions for Weifang generator set
Avoid using open flames to assist combustion: It is strictly prohibited to use open flames to assist combustion when starting a diesel generator. The air filter cannot be removed, and cotton yarn dipped in diesel can be used to ignite and make a flame starter placed in the intake pipe of the diesel generator to assist combustion during start-up.
Wearing and operating standards: In winter, employees wear more clothing and should prevent clothing or hair from getting tangled into rotating devices. It is strictly prohibited to wear gloves for operation.
Battery maintenance: Avoid starting the unit with the battery at low temperatures, as the battery capacity will not output continuously at low temperatures and prolonged discharge may cause battery failure.
In summary, the maintenance of Weifang generator set in low temperature winter involves cooling system, lubrication system, fuel system, fire prevention and electrical safety, as well as multiple other aspects. Only by comprehensively and meticulously carrying out these maintenance tasks can we ensure the normal operation and long-term stability of the generator set in winter.
