控制收获机上发动机冷却液温度在适宜的范围至关重要。本文主要介绍把散热器内的风扇的动力改为液压驱动。由控制器采集发动机冷却液温度,并作为控制对象。通过控制泵的排量来实现对马达速度的控制(即对风扇速度的控制);定时或者在判定散热效果不良情况下,使马达反转,用来吹掉吸附在散热器护罩上的农作物秸秆;在尽可能节能的情况下充分对冷却液温度进行散热,有助于提升发动机性能,减少能源浪费。
It is important to control the temperature of the engine coolant on harvesters within the proper range. This article mainly introduces the fan power inside the radiator changed to hydraulic drive. The controller collects the engine coolant temperature and controls it. Control the speed of the motor (ie control the speed of the fan) by controlling the displacement of the pump; reverse the motor timing or determine if the cooling effect is not good, to blow off the crops adsorbed on the radiator cover Stalks; Heat up the coolant temperature sufficiently to save energy as much as possible, helping to improve engine performance and reduce energy waste.
