1. Too much gearbox oil: If the gearbox oil is too much, the gearbox will be overloaded during operation, causing oil leakage. The gearbox needs to be repaired and checked in time.
2. Damage to the oil rubber seal: Damage or aging of the oil rubber seal will cause oil leakage, and the seal needs to be checked and replaced.
3. Vehicle chassis collision: Vehicle chassis collision can easily damage the generator and cause oil leakage. Pay attention to driving methods and avoid collisions.
4. The oil radiator is not tightly sealed: The oil radiator is not tightly sealed, which will cause oil leakage. The oil radiator needs to be checked and repaired.
5. The rear cover of the cam bearing is not tight: The rear cover of the cam bearing is not tight, which will cause oil leakage. The rear cover of the cam bearing needs to be adjusted.
6. Damage to the front and rear oil seals of the crankshaft: Damage to the front and rear oil seals of the crankshaft will cause oil leakage. The oil seals need to be checked and replaced.
7. Deformation of the generator bracket plate: Deformation of the generator bracket plate will cause oil leakage, and the bracket plate needs to be checked and repaired.
8. Burning through of the upper and lower cylinder head gaskets: Burning through of the upper and lower cylinder head gaskets will cause lubricating oil to leak out, and the faulty parts need to be checked and repaired.
9. Uneven glue application between the oil pan and the generator cylinder body: Uneven glue application between the oil pan and the generator cylinder body will cause oil leakage, and the oil pan and the generator cylinder body need to be checked and repaired.
10. Unqualified paper gasket: Unqualified paper gaskets of diesel generators (such as insufficient thickness, improper storage, wrinkles and deformation, etc.) will cause oil leakage, and the faulty parts need to be checked and repaired.
11. Excessive oil pressure: Excessive oil pressure will cause oil leakage on the static joint surface, and the oil pressure needs to be checked and the faulty parts need to be repaired regularly.
12. Static joint surface quality: Poor quality of static joint surface (such as flatness and roughness that do not meet design requirements) will lead to oil leakage, and it is necessary to regularly check and repair the faulty parts.
Measures to prevent and solve oil leakage in generator sets include:
Use sealing adhesives: Sealing adhesives can seal, prevent leakage, tighten and block gaps to prevent oil leakage.
Synchronous operation method: Synchronous operation method should be adopted during disassembly, and the bolts should be tightened as evenly as possible to avoid deformation of parts.
Use puller: Use puller as much as possible in places with conditions to fundamentally solve the synchronization problem.
Regular inspection and maintenance: Regularly check and repair faulty parts to ensure that the equipment accuracy and storage and transportation conditions meet the requirements.
Through the above measures, the problem of diesel generator oil leakage can be better prevented and solved to ensure the normal operation of the equipment.
