介绍天津工程机械研究院自主研发6 t级节能装载机的独立散热冷却系统,该系统由风扇、定量泵、定量马达、电比例溢流阀、温度传感器、温控阀和控制器等部件组成,通过一个独立可控的液压系统驱动冷却风扇,采取模糊控制方式,对发动机冷却液、液压油、变矩器油3种介质同时进行散热。该冷却系统具有结构简单,控制准确,操作方便,安全可靠,冷却介质温升快,性能稳定等特点。
Introduction Tianjin Research Institute of Construction Machinery independent research and development 6 t-class energy-saving independent loader cooling system, the system consists of fans, pumps, quantitative motors, proportional pressure relief valve, temperature sensors, temperature control valves and controllers and other components, Driven by an independently controllable hydraulic system, the cooling fans are controlled by a fuzzy control method to dissipate the heat of the engine coolant, hydraulic oil and torque converter oil simultaneously. The cooling system has the advantages of simple structure, accurate control, convenient operation, safety and reliability, fast cooling medium temperature rise and stable performance.
