大家知道,柴油机随着外界负荷的变化,转速亦发生变化:负荷轻时,柴油机转速低,调速器飞球张开推动油泵齿条向减油方向移动;反之,柴油机负荷重,在调速器弹簧的作用下,推动油泵齿条向增油方向移动。一般的油泵调速器,当外界负荷增加到一定程度时,供油量可以适当加大至一定程度,调速器中的这种装置称之为超供器。195型柴油机的油泵调速器中没有超供装置,这样柴油机容易在低转速高负荷
As we all know, with the changes of external load, the engine speed also changes: when the load is light, the speed of the diesel engine is low and the governor fly ball is open to move the pump rack to the direction of reducing oil; on the contrary, the diesel engine is heavy, Under the action of the spring, push the pump rack to move toward the direction of increasing oil pressure. General pump governor, when the external load increases to a certain extent, the fuel supply can be appropriately increased to a certain extent, this device in the governor called super-donor. 195 diesel engine pump governor is not super-device, so that diesel engine easily at low speed high load
