Correctly Using the Heating System of Volvo Generators

When Volvo generators are used in winter, due to the low ambient temperature, it may be difficult to start or even fail to start, or the body may freeze and crack due to the low freezing point of the cooling water. So in severe winter, in order for the Volvo generator to resume normal operation, it is necessary to turn on and use the Volvo generator heating system: coolant heating system, oil heating system, and fuel heating system. Volvo generator manufacturer analyzes the necessity and sufficient reasons for opening and using the heating system in winter.

Fuel system heating device: In order to avoid Volvo generators being blocked by diesel and unable to quickly enter the operating conditions, the outdoor temperature is usually below 5 degrees Celsius. Turn on the electric heating function of the Volvo generator during winter.

Because diesel contains a certain amount of wax, during low winter temperatures, these wax will gradually separate out and even cause diesel to condense and become inactive. When the wax separated from diesel starts to block the filter and affect the normal fuel supply of the oil circuit, the temperature at this moment is called the cold filter point of diesel.

Taking No. 0 diesel as an example, its condensation point is 0 degrees Celsius and its cold filtration point is 4 degrees Celsius. Usually, when the outdoor temperature is below 5 degrees Celsius, the electric heating function is turned on to saturate the condition of diesel and can be put into operation at any time. Electric heating consumes a certain amount of electrical energy, therefore, attention should be paid to turning on this function at the appropriate temperature. For example, when the temperature is much higher than the cold filtration point of the diesel used, this function should not be turned on again. Overall, turning on the electric heating function at the appropriate temperature can enable Volvo generators to be efficiently put into operation at any time.

Heating coolant system: When the temperature decreases in winter, the coolant of Volvo generators also decreases or even solidifies with the decrease in temperature. Therefore, generator manufacturers generally recommend that Volvo generator users use antifreeze as the cooling medium to prevent the body from freezing and cracking due to the low freezing point of the cooling water. In this situation, it is necessary to open the coolant heating system to ensure a certain temperature of the coolant, This temperature is also a guarantee for the rapid start-up of Volvo generators.

Winter heating of engine oil: Volvo generator oil used in summer has poor fluidity, which brings certain resistance when starting Volvo generators. At this time, the generator manufacturer recommends that users use winter engine oil correctly. In addition, to ensure the flexibility of Volvo generator starting, the engine oil heating system must be opened, Not only does it ensure the temperature when the engine starts, but it also ensures sufficient oil fluidity and reduces the difficulty of starting in winter.
