柴油发电机组风扇的作用是增大流经散热器芯部空气的流速，提高散热器的散热能力，柴油发电机组风扇一般具有风量大，冷却效果好，且噪声小的特点，按柴油发电机组机型和标定功率的不同，可配用不同规格的风扇，风扇有吸风式和吹风式两种结构，用户可根据需要在订货时任选一种。

The function of the diesel generator radiator fan is to increase the flow rate of the air flowing through the core of the radiator and improve the heat dissipation capacity.Radiator fans generally have the characteristics of large air volume, good cooling effect, and low noise. Different types and rated powers can be equipped with fans of different specifications.There are 2 different structures which are suction type and blowing type.You can choose one of them when ordering according to their needs.

柴油发电机组工作时，按其旋转方向，根据风叶的凹弧面应为压风面的原则来判断风扇是吹风式还是吸风式。例如面向柴油机前端看，如果凡扇的压风面（凹弧面）面向您时，即为吹风式；反之非压风面（凸弧面）面向您时则为吸风式。安装风扇时切勿装反，否则风叶的非压风面将成为压风面，影响风扇风量，使散热器的散热效果下降。

When the diesel generator is working, it is judged whether the fan is a blowing or a suction type according to the direction of rotation and the principle that the concave arc surface of the fan blade should be the compressed air surface. For example, when you stay at the front end of the diesel engine, if the fan's compressed air surface facing you, it is a blowing type.On the contrary, when the non-pressure air surface faces you, it is a suction type. When installing the fan, do not install it backwards, otherwise the non-pressurized surface of the fan blade will become the pressurized surface, which will affect the fan's air volume and reduce the heat dissipation effect of the radiator.

柴油发电机组是一种精密的机械设备，任何一个部件都需要确保完好才可以安全且高效的运行，风扇也不例外，用户应注意以下三个事项：

Diesel generator is a kind of precision mechanical equipment. Any part needs to be intact before it can run safely and efficiently. The fan is no exception.Please pay attention to the following notes.

1、定期检查风扇的安装是否牢固，所有风叶是否有明显的碰弯变形现象，如有发现应即更换，以免因风扇的平衡度变差而折断风叶和打坏水散热器等事故的发生。

Regularly check whether the installation of the fan is firm, whether all the blades have obvious bending and deformation, if found, replace them immediately, so as to avoid the occurrence of accidents such as breaking the blades and radiator due to the deterioration of the fan's balance.

2、定期调整三角橡胶带的松紧程度，太紧会引起轴承过度磨损；太松又将使风扇的风量下降，影响发电机组散热效果。

Regularly adjust the tightness of the triangular rubber belt. Too tight will cause excessive wear of the bearing; too loose will reduce the air volume of the fan, which will affect the heat dissipation effect of the generator.

3、定期向直通式压注油杯内加注适量的黄油。

Fill the straight-through pressure oil cup with proper amount of grease regularly.
