A Comprehensive Guide To Check Diesel Generator Sets Thoroughly And Clear The Trouble

1800rpm water cooled diesel engine generator sets can be divided into two parts: diesel engine and generator. The diesel engine has two major components and five major systems. The two major components are the stationary components and relative motion components. For example, the cylinder cap, cylinder block, cylinder liner, etc. belong to the stationary components, while the piston, connecting rod, and crankshaft are relative motion components. The five major systems are: fuel system, lubrication system, cooling system, gas distribution system, starting and charging system.

 

 

1. Judgment of the fault should be analyzed from the whole, and troubleshooting should be comprehensive.

The systems, components, and parts of the diesel generator set are closely related. If a component or a system fails, other components or systems are generally involved. Therefore, a fault can not be judged in isolation, the cause of the fault should be analyzed from the whole and the fault should be eliminated in time.

 

 

2. Try to reduce disassembly as possible as you can when looking for the fault of diesel generator sets.

When troubleshooting the diesel generator set, it should be disassembled on the basis of correct analysis and judgment. Parts cannot be disassembled blindly. Before disassembly, the structure, working principle and fault characteristics of this type of diesel generator sets should be understood and mastered. It can only be disassembled on the basis of scientific and careful analysis.

 

For example: during the use of a diesel generator set, when it is found that the power of the 6135AZD-1 water cooled 6 cylinder diesel engine is insufficient, if you have not found which is the reason or which component is damaged and disassemble the parts blindly, then not only will the time for troubleshooting be prolonged, but the relative position of other parts may be changes. Therefore, when troubleshooting the diesel generator set, it is necessary to pinpoint the fault location based on correct analysis and judgment, and then disassemble the related parts.

 

 

3. Find faults carefully and combined with methods such as watching, listening, touching and smelling.

After the diesel generator set fails, a comprehensive inspection should be carried out on the basis of careful search, combined with methods such as watching, listening, touching and smelling.

 

Watching: Check the external characteristics of the diesel generator set during operation, such as whether the smoke exhaust is abnormal, whether the color of the lubricating oil is normal, whether the fuel supply system has leaks, whether there is water leakage and oil leakage in the cooling system and the lubrication system, whether the various instrument indications of the diesel generator set are abnormal, whether the nuts of various moving parts are loose, whether the wiring of the starting line of the electric starting water cooled 6 cylinder diesel engine is correct, and whether there is "ironing" phenomenon inside the generator control cabinet, whether the circuit has short circuit or open circuit phenomenon.

 

Listening: Mainly listen to the abnormal sound of the diesel generator set during operation, such as whether the explosion sound of diesel burning in the combustion chamber is uniform, whether the impact sound of the piston, connecting rod and crankshaft is abnormal during the operation, whether the valve and the transmission gear of the 12 cylinder 420kw 4 stroke diesel engine have abnormal noise.

 

Touching: Whether the exhaust temperature of each exhaust pipe is the same after the diesel generator set is started, and whether the temperature of the generator casing is too high, whether the temperature of the upper water pipe and the lower water pipe of the water pump is consistent, whether the temperature of the oil pipe or oil pan is equal to that of the oil temperature meter, whether the instructions are consistent, whether there is abnormality in the vibration of the body, etc.

 

Smelling: Whether there is any burning smell in the power supply process of the diesel generator set, such as the internal wiring and components of the generator control cabinet, the stator and rotor inside the generator, whether the kpv660 660kw turbocharger diesel engine has the smell of burning oil, etc.

 

 

4. Search by components when troubleshooting

The diesel generator set can be divided into 3 parts: diesel engine, generator and control box. When troubleshooting the diesel generator set, it is necessary to combine the structural characteristics of the diesel engine, generator and control box. For example, for the phenomenon of blue smoke in the exhaust pipe after the diesel engine is started, it should be combined with the structural characteristics of the five major systems and two major components to search.

 

Among the major systems of the diesel engine and the components of the generator, no matter which system or component fails, the diesel generator set will not work properly.
