The unstable high-speed operation of the gas engine of the generator set at no load is mostly related to the governor. Generally, most of the working output torque * large medium speed range, because this speed range has good power performance and fuel saving. The judgment and elimination steps of unstable high-speed operation of diesel engine are as follows:; Check whether the speed stabilizing spring is damaged. The speed stabilizing spring not only plays a role in the stability of idle speed, but also has an impact on the stability of high-speed operation. If the constant speed spring is stuck due to wear or softened due to long-term fatigue, it must be repaired or replaced.

檢查怠速副彈簧是否損壞。調(diào)速率的大小是靠正確調(diào)整調(diào)速彈簧來達到額。調(diào)速彈簧經(jīng)長期使用，彈性系數(shù)會因疲勞而改變，從而使調(diào)速率變大，即使勉強使用也不會得到良好的調(diào)速效果，*好予以更換。

Check whether the idle auxiliary spring is damaged. The speed regulation rate is achieved by correctly adjusting the speed regulation spring. After long-term use, the elastic coefficient of the speed regulating spring will change due to fatigue, so as to increase the speed regulating rate. Even if it is reluctantly used, it will not get good speed regulating effect, and it will be replaced.

對RSV型調(diào)速器，其高速控制還有怠速副彈簧在起部分作用，設(shè)置在背面中部的怠速副彈簧不僅在怠速時起主導(dǎo)控制作用，而且在高速運轉(zhuǎn)時還與調(diào)速彈簧共同對高速控制起作用，若此彈簧性能不好也會影響發(fā)電機無負荷*高轉(zhuǎn)速的控制。因此怠速彈簧損壞或調(diào)整不當(dāng)會對高速運轉(zhuǎn)的控制產(chǎn)生不好影響，必須進行調(diào)整或更換。

For the RSV governor, the high-speed control also has the idle auxiliary spring playing a part. The idle auxiliary spring set in the middle of the back not only plays a leading control role at idle speed, but also plays a role in high-speed control together with the speed regulating spring at high speed. If the performance of this spring is not good, it will also affect the control of no-load * high speed of the generator. Therefore, the damage or improper adjustment of idle spring will have a bad impact on the control of high-speed operation, which must be adjusted or replaced.
