How To Prevent Runaway Accidents Of Cummins Diesel Generator Sets

Oct. 22, 2021

When the speed of Cummins diesel generator sets continues to increase, the sound produced by the diesel engine becomes denser, similar to howling. At this time, it can be judged that the Cummins diesel generator set has a runaway accident. The runaway accidents usually happen suddenly. If you don’t handle it properly, it can bring serious harm to the computer room or the unit in a very short time, and it also threatens the personal safety of the unit operator. Therefore, the user must take precautions. Prevention is the lowest cost treatment measure. The following are some measures to prevent running accidents of Cummins diesel generator sets compiled for you by the generator manufacturer-Jiangsu Starlight Electricity Equipments Co.,Ltd.


1. During the use of Cummins diesel generator sets, the vehicle speed should be strictly controlled: not too high or too low. In daily use, the speed should be controlled at about 1500 revolutions per minute.


2. Strictly implement the itinerant inspection system: once the Cummins diesel generator set is found to have its own speed change, high and low, or self-increasing, sudden increase in sound, etc., it should be shut down for inspection or reported immediately.

3. Strengthen daily maintenance work.

(1) Keep the oil and water of Cummins diesel generator set clean, appropriate, and without deterioration. Especially the oil level in the high-pressure fuel injection pump should be strictly controlled at the required position. The liquid level is too high and the viscosity is too high, the resistance is increased, which limits the governor's governing effect. The liquid level is too low or there is no liquid level, causing the parts in the governor to wear out, and the speed governing function decreases or loses. As a result, a speeding accident occurs, so we must resolutely prevent the occurrence of no or insufficient lubricant in the governor.


(2) Carefully check the fastening of the bolts of each part of the Cummins diesel generator set to ensure that it is intact and not loose. In particular, prevent the screw plug at the lower part of the governor housing from loosening or falling off, resulting in loss of lubricating oil in the governor, abrasion of parts in the governor, rack jamming, bearing damage, etc., losing the governing effect and causing runaway.


(3) Increase the inspection density of the high-pressure fuel injection pump governor and camshaft box, the lubricating oil surface in the bottom case, the oil pressure gauge and the connecting oil pipe, the oil cooler and the connecting pipeline, the liquid level in the water tank and the water quality, etc., to ensure the liquid level is appropriate, the tubing is intact, and there is no looseness, openness, or leakage.


The above are some methods that Jiangsu Starlight Electricity Equipments Co.,Ltd. has compiled for you to effectively prevent Cummins diesel generator sets from runaway accidents. For Cummins diesel generator sets, especially oil pump governors, users must install, maintain, and debug according to technical requirements. The fuel should be clean and the grade should be correct to avoid accidents caused by excessive fuel supply.
