How to calculate the vents of the generator set?

The nacial ventilation area should be 1.25 times the terminal area of the water tank.

For example, the end face of the water tank is 1 square meter, and the surface of the bulkhead is at least 1.25 square meters. If there is no shutters, if there is no shutters, it must also consider its effective area, such as an effective area of 80%, then the air outlet area is at least 1.25 square meters divided by 0.8 equal to 1.56 square meters

At the position of the air outlet, the wind will also consider the wind, that is, the wind is flowing with the diesel machine, with part of the heat (note: the diesel engine itself can withstand the temperature of 60 ° C, while the air imports involved in the combustion cannot exceed 40 ° C, so Should reasonably select the installation location of the air filter

The basic knowledge of power generation is introduced: the water tank installation position is unreasonable, often forming a hot air reflow short circuit, this hazard is highly manifested in the following aspects

1. Make Huajing's pothe temperature (ATB) to the machine (ATB), sometimes more than 10 degrees

2. If the normal use ambient temperature of the machine is 50 ° C, it may drop 32 degrees Celsius, which is very easy to open.

3. Since the ambient temperature is changed, the cooling effect of the intercooler is lowered, and the intake volume is reduced, and the exhaust temperature rises sharply. If the air is heated 10 degrees Celsius at this time, some machine rises from about 100 ° C.

4, at this time, the diesel engine is very low, the fuel consumption is increased.

5, diesel engine work at an abnormal high temperature, the moving parts will accelerate wear

Avoid reflow
