What Are The Reasons for The Silent Generator Set Speeding?

Dec. 06, 2021

In our daily life, there will be occasional power outages. The silent generator set as a backup power supply solves this problem. However, in the use of silent generator sets, sometimes the silent generator set may exceed the speed. What is the reason for this situation will make us very puzzled. Next, Starlight Power Generation Equipment will talk about the reasons for the speedinging of the silent generator set and the solution.

1. Reasons for speeding

(1) The meter connection is faulty.

(2) The sensor, control panel or connection is faulty.

(3) The speeding protection value is set too small, and the user should slightly adjust the speeding protection value of the silent generator set to not exceed 17%.

(4) The silent generator set adopts a mechanical speed regulation structure. Please check whether the throttle lever is flexible and make sure it is adjusted correctly.

(6) For the electronic speed control system, check whether the throttle lever is flexible and whether the actuator operates correctly.

(7) The fuel pump is issued a card or the electronic actuator is stuck, causing the throttle to open to the position.

2. The solution

(1) Once the diesel engine has an speeding fault, the following measures should be taken quickly to force the diesel engine to stop immediately.

a. Quickly retract the accelerator pedal to the stop fuel supply position.

b. For fuel injection pumps with exposed fuel supply rods or rack rods, quickly pull the rods back to the fuel stop position.

c. For diesel engines equipped with decompression devices, the decompression handle should be quickly pulled to the decompression position, so that the diesel engine stops because there is no compressed gas.

d. If there is a shut-off device for the intake pipe, immediately turn off the flameout device or quickly block the air filter inlet with a cloth, and turn off the fuel tank switch to cut off the gas path and the oil path, and stop the oil and gas supply. , So that the cylinder suffocates and shuts down.

e. Put the transmission into high gear in time, depress the brake pedal to the end, and slowly lift the clutch pedal to force the engine to stop.

(2) The cause is diagnosed after the shutdown

a. If the accelerator pedal is raised quickly and the engine does not continue to rise after reaching the speed, the accelerator pedal rod or arm is mostly stuck.

b. If the accelerator pedal is raised quickly, the engine speed cannot be reduced or stopped immediately, usually because the governor is faulty.

c. If the engine speed continues to increase after the accelerator pedal is picked up, it indicates that the fuel injection pump is malfunctioning.

d. If the fuel supply system is good, it means that there is extra fuel or oil in the cylinder.

3. After troubleshooting, reset the alarm signal on the control screen


The above is the full content of the reasons and solutions for the speeding of the quiet generator set. I hope that it will be helpful when similar situations arise in the future, but if you encounter special problems, you still need to find a repairman to solve it.
