Diesel generator common fault solution

1. Diesel engine use status

Is there any noise before the fault occurs? Is the load or light load operation? Acceleration or deceleration? Does the oil pressure or water temperature change?

Did there be abnormal dust or fumes at that time? What are the weather conditions and how big is the wind?

What was the road grade at that time? What was the first perceived fault? How much oil, fuel, and coolant consumption? Zui has changed recently? What is the concentration of smoke?

Is the diesel engine throttle response sensitive? Is the deceleration normal? Is the shutdown satisfactory? Is the low temperature start-up satisfactory? Is there a flameout or a lack of fire?

What kind of fuel is used? What is the level and source of fuel? Will it surge when running at idle or full speed? Can it be used for long-term idle operation?

2. Maintenance of diesel generator history

Has the diesel engine been repaired recently? What kind of maintenance is it?

Has this failure occurred before? When was the last adjustment? When did Zui replace the oil and fuel filter?

Is the maintenance system strict? How is the fuel obtained and stored: What is the maintenance type and the level of lubricant used?

How many kilometers or how many hours does the diesel engine run? Who will repair and adjust?

When replacing the oil filter, have you checked the filter element of the full-flow oil filter? Have any metal impurities been found?

3. Generator set observation results

Is the diesel engine clean or dirty? How is the belt tight? Is there any leakage of inorganic oil, fuel or water from the outside? Is there any overheating?

Have you made any temporary repairs on the diesel engine (the parts are not fastened, the parts are damaged, etc.).

What is the sound of the diesel engine at idle? Does the pulley have any wiggle? Have you recently repaired or replaced any parts?

Are there any non-standard parts on the diesel engine that are not part of the diesel engine? Are there any bad pipes?

Is the oil level, water surface and fuel oil level highly satisfactory (if the bearing topic is involved, pay attention to the oil condition. This happened once, the bearing was damaged due to insufficient oil, and the operator only went to the crankcase afterwards. Refill with new oil).

During disassembly, is there any odor, carbon deposits, and sludge in the diesel engine? Are there any other bad conditions under the rocker cover?

4. Begin to test the problems that the mechanics should consider before the diesel generator set

Simply asking and understanding the situation, the generator set can not solve any problems. Therefore, it is necessary to understand the situation related to the fault before the inspection, and to see the mutual dependence of each topic before making a judgment.

Utilizing all available and existing test instruments is helpful for thinking processes (thinking), but it may not always be used.

The mechanic must be familiar with the knowledge of the diesel sail model, equipment type and handling. Equipment on diesel engines, such as torque converters, coolers and stepless governors, must be considered.

Most diesel users are resentful of unnecessary downtime and premature disassembly, so it is important to focus on planned and targeted inspections and to make each inspection thorough and successful. generator

Since any part of the diesel engine has a problem, it may affect the operation of the entire generator set. Therefore, you must have extensive experience in identifying the operation of the diesel engine. The important condition for successfully troubleshooting is to use the diesel engine and its parts that you have grasped. The knowledge of the situation to solve the problem of generator set failure is a kind of intellectual operation activity.

It is not difficult to find certain checks when troubleshooting and troubleshooting. The information obtained must be related to the fault. Can't say that the generator set in front of you has the same fault as a diesel engine last week, and thinks that the cause of the fault is the same.
