Wittgen: V Classroom | Introduction to Cooling Fan Drive Mode Technology

In the last issue of《Dimensional classroom》Li，Xiaowei introduced the inspection and operation of Wittgen Milling Machine in case of insufficient sprinkling in the milling process.，And the current period《Dimensional classroom》It will be very attractive to the Uyghur fans who control technology.，The teacher of the training center will give you a detailed explanation of the different driving modes of the cooling fan of construction machinery.，There is a lot of information in this class.，Full of dry goods。

The general construction machinery cooling fan has three different driving modes.：The cooling fan is connected to the engine drive shaft，Mode driven by the engine、Mode in which the cooling fan is driven by a hydraulic motor，And a silicon oil clutch cooling fan model。

The advantage of the engine-controlled cooling fan drive mode is that the fan speed is directly dependent on the engine speed，Its simple and direct control mode can keep the cooling system in a strong working state.；The control mode of the cooling fan driven by the hydraulic motor is to control the fan speed by precisely controlling the motor speed，It can also achieve precise control.，The different driving modes of these two cooling fans also have their own advantages and disadvantages.。

Vogler is equipped Ergo Plus The Paver of the control system uses a silicone oil clutch cooling fan.，This mode can be directly connected to the engine drive shaft.，It is also possible to control the speed of the cooling fan using the amount of silicone oil entering。Therefore, the cooling fan of the silicon oil clutch can rotate the engine fan at 800-Precise control at 2100 rpm，And has that advantage of energy conservation、Emission reduction、Noise reduction and the like.，What is the reason behind this?？Follow Xiaowei into today's Weiwei class.。
