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.

检查怠速副弹簧是否损坏。调速率的大小是靠正确调整调速弹簧来达到额。调速弹簧经长期使用，弹性系数会因疲劳而改变，从而使调速率变大，即使勉强使用也不会得到良好的调速效果，*好予以更换。

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.

对RSV型调速器，其高速控制还有怠速副弹簧在起部分作用，设置在背面中部的怠速副弹簧不仅在怠速时起主导控制作用，而且在高速运转时还与调速弹簧共同对高速控制起作用，若此弹簧性能不好也会影响发电机无负荷*高转速的控制。因此怠速弹簧损坏或调整不当会对高速运转的控制产生不好影响，必须进行调整或更换。

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.
