风扇驱动控制装置及建筑机械
摘要：
本发明提供一种风扇驱动控制装置及建筑机械，该风扇驱动控制装置具有：利用从由发动机驱动的液压泵供给的液压油驱动冷却风扇的液压马达、调节流入液压马达的液压油的流量的流量调节机构、检测由冷却风扇冷却的被冷却流体温度的温度传感器、基于温度传感器的检测值检测用于对发动机的输出进行操作的油门开度的油门开度传感器、设定流入液压马达的液压油的目标流量的目标流量设定机构、基于油门开度传感器的检测值修正目标流量的目标流量修正机构、以及根据由目标流量修正机构修正后的目标流量生成向流量调节机构发出的控制指令的控制指令生成机构。
摘要（英）：

The invention provides a fan drive controlling device and a construction machine. The fan drive controlling device is provided with a hydraulic motor for driving a cooling fan by hydraulic oil supplied from a hydraulic pump driven by an engine, a flow rate adjusting means for adjusting the flow rate of the hydraulic oil flowing into the hydraulic motor, a temperature sensor for detecting the temperature of fluid cooled by the cooling fan, an accelerator opening degree sensor for detecting, based on the value detected by the temperature sensor, the degree of opening of an accelerator for operating the output of the engine, a target flow rate setting means for setting a target flow rate of the hydraulic oil flowing into the hydraulic motor, a target flow rate correcting means for correcting the target flow rate based on the value detected by the accelerator opening degree sensor, and a control command generating means for generating a control command for the flow rate adjusting means based on the target flow rate corrected by the target flow rate correcting means.
