在双机并车装置中,两台柴油机的负荷由于受到调速器特性及燃烧状况的影响,很难使其在使用转速及整个负荷范围内都能平衡一致,所以就必须在两机之间装置某种形式的负荷平衡装置。在已有的双机并车装置中所用的变速主机,它的转速与负荷特性是一定的,因此可用转速指令或检出的信号去控制调油轴达到负荷平衡,曾采用这种原理设计过二、三种负荷平衡装置。但这些装置对于定速柴油机及变负荷的情况就不适用。
In the double engine and car assembly, the load of two diesel engines is affected by the governor characteristics and combustion conditions, so it is difficult to balance the two engines in the speed of use and the entire load range, so it must be between two machines Some form of load balancing device. In the existing double-machine and car assembly used in the variable speed mainframe, its speed and load characteristics are certain, so you can use the speed command or the detected signal to control the oil to achieve load balancing shaft, has been designed using this principle Second, three load balancing device. However, these devices do not apply to fixed-speed diesel engines and variable load conditions.
