Research on Intelligent Control Method of Hydraulic Fan Based on Temperature
According to the fan set speed and engine speed,query the feed forward opening MAP of the sole-noid valve to obtain the feed forward opening value.The traditional heat dissipation mode based on the tempera-ture of engine can'tsatisfy actual heat dissipation requirement.Large heat dissipation and simple control and high reliability of hydraulic fan,so it's widely used in construction machinery industry.Exceptional,the reverse feature can effectively clean the magazines on the intercooler.So htdraulic fans with reverse feature are more and more fa-vored by construction machinery industry.This paper presents an intelligent control method for hydraulic fan,It can accuracy control hydraulic fan via the engine controller,and meet the requirements of heat dissipation and cleaning.This control methed is simple and effective pass vehicle test.
