一、变充量偶合器的设计指导思想用液力偶合器驱动冷却风扇,虽然在东方红<1>型内燃机车上已是较成熟的部件,但其控制方式比较简单,只能实现要么就是充满,要么就是不充。在柴油机运用和科学实验的实践中已证明,冷却水的温度对柴油机的工作过程与经济性,以及主要件的磨损有明显的影响。同时,由于柴油机功率的下降,或者气温低于计算温 First, the variable coupling design guidelines Coupled drive fluid cooling fan, although the East Hong <1> type diesel locomotive is already more mature components, but the control is relatively simple, can only be achieved either Full, or just not enough. In the practice of diesel engine application and scientific experiment, it has been proved that the temperature of the cooling water has a significant impact on the working process and economy of the diesel engine, as well as the wear of the main parts. At the same time, due to the decline of diesel engine power, or the temperature is lower than the calculated temperature
