When releasing antifreeze in winter for silent generator sets, the following precautions should be taken to ensure the normal operation of the unit and extend its service life.
Silent generator set water tank antifreeze:
Ensure that the water tank does not freeze. Long term rust and antifreeze can be added or electric heating equipment can be used to ensure that the room temperature is above freezing point to prevent the water tank from freezing.
When the local temperature is below 4 ℃, all water in the generator set body, cooler, water tank, and water pump should be drained to prevent water from freezing and damaging the radiator of the water tank.
Preheating and startup of silent generator set:
When the temperature is below 5 ℃, the silent generator set should be preheated with hot water or steam before starting, and should be preheated to above 30-40 ℃ before starting. The main purpose of preheating is to increase the temperature of the cylinder, thereby heating the temperature of the atomized diesel, as diesel engines are compression ignition engines.
After starting, run at low speed for 3-5 minutes to increase the overall temperature of the generator set and check the working condition of the lubricating oil. It can only be put into normal operation after it is normal.
Silent generator set oil and fuel:
In winter, it is advisable to choose engine oil with a slightly thinner viscosity to ensure its fluidity at low temperatures.
Use winter fuel and pay special attention to the water content in the fuel to avoid clogging the oil circuit.
Silent generator set cooling system:
It is recommended to add antifreeze to the cooling system to prevent it from freezing at low temperatures. If antifreeze has been added, there is no need to drain water when the temperature drops.
After parking, if the water temperature drops to 10-50 ℃, all drain switches must be turned on to drain all cooling water.
Silent generator set device maintenance:
In winter, due to the deteriorating working environment, the requirements for the silent generator set air filter and diesel filter become higher. It is necessary to replace the air filter in a timely manner to prevent filter blockage from affecting the normal operation of the engine.
Check the concentration of antifreeze to ensure its effectiveness.
When there is water vapor in the air storage cylinder, it should be discharged frequently to avoid freezing and causing brake failure.
Storage and insulation of silent generator set:
In severe cold seasons and regions, generator sets should not be stored outdoors to prevent equipment damage from the cold.
If the generator set needs to be stored outdoors or used in a cold environment, insulation measures should be taken, such as wrapping the generator set with insulation materials.
In summary, silent generator sets need to pay attention to multiple aspects when releasing antifreeze in winter, including water tank antifreeze, preheating and starting, oil and fuel selection, cooling system maintenance, equipment maintenance, and storage and insulation. Only by ensuring the correct operation and maintenance of these aspects can the normal operation and extended service time of the generator set in winter be guaranteed.
