020004349 engine cooling visco fan clutch for KAMAZ russia truck.

The fan clutch is a device that automatically adjusts the air volume of the fan with changes in the engine temperature. In this way, not only can the engine be guaranteed to work at the most suitable temperature, but also the warm-up time can be changed to increase the effective power of the engine.
 

Fan clutch function:
a. When no fan is needed for cooling, stop the rotation;
b. When the fan does not need large air volume for cooling, its value can be reduced;
c. When the fan needs large air volume to cool, it converts to high-speed rotation.
d. Control the speed of the fan within an appropriate range, so as to reduce noise and improve engine economy.
Installation position: between the fan pulley and the cooling fan
Fan clutches used in automobiles: almost all silicon oil fan clutches are used in automobiles.

Why use Fan clutch

- Energy saving
Compared with Hub saving 5% energy.
- Environmental protection
Reduced exhaust emissions

- Noise reduction
Make the truck low noise when it working
- Shock absorption
Increase the engine and fan blade life

The fan clutch includes night pressure, electronic control, temperature-sensitive silicone oil, etc.
Now I will explain to you the working principle of the silicone oil fan clutch. Hope it helps you:
The silicone oil fan clutch uses silicone oil as the medium and uses the high viscosity of silicone oil to transmit torque. The temperature of the air behind the radiator is used to automatically control the separation and engagement of the fan clutch through a temperature sensor. When the temperature is low, the silicone oil does not flow, the fan clutch is separated, and the fan speed slows down, basically idling. When the temperature is high, the viscosity of the silicone oil causes the fan clutch to be combined, so the fan and the water pump shaft rotate together to regulate the temperature of the engine.
