Oil leaking from the exhaust pipe of the diesel generator set is mainly caused by the long-term low-load operation of the diesel generator set. Since there are many places in the diesel generator that use pressure seals, such as between the cylinder liner - piston - piston ring and between the compressor and the compressor rotor shaft, this type of seal is usually only available when the engine is running under about 1/3 load. It can work fully, but slight leakage may occur when the load is small. Therefore, users should pay attention to the correct use of the unit when using the diesel generator set and cannot allow the unit to operate at low load for a long time to avoid engine failure.

What should be paid attention to when assembling a diesel generator together?
We ask customers to tilt the exhaust pipe downward 5-10 degrees when installing the unit to prevent rainwater from entering the pipe exhaust and cause major accidents.

Many customers do not pay much attention to the process of assembly after purchasing a diesel generator. sets. For example, the assembly environment is very dusty, which may cause friction damage after entering the unit equipment. For example, the assembly environment is relatively humid, which can easily allow moisture to penetrate the interior of the equipment. Regarding these overlooked details, Tenglong Generator Set made a summary:
When assembling the generator set, please pay attention to:
1. The installation site should be well ventilated and the generator The end must have sufficient air inlet and good air outlet at the end of the diesel engine. The air outlet area should be more than 1.5 times larger than the water tank area.
2. The area around the installation site should be kept clean, and items that may generate corrosive gases and vapors such as acids and alkalis should be avoided nearby. Fire extinguishing devices should be equipped wherever possible.
3. When used indoors, the smoke exhaust pipe must be directed outside. The diameter of the pipe must be ≥ the diameter of the silencer smoke outlet pipe. The connected pipe should not have more. more than 3 elbows to ensure that the exhaust pipeement est To ensure smooth flow of smoke, the pipe should be tilted downward 5 to 10 degrees to avoid rainwater injection; If the exhaust pipe is installed vertically upwards, a rain cover must be installed.
4. When the foundation is concrete, flatness should be measured with a level ruler during installation to ensure the unit is secured on a level foundation. There must be special anti-vibration pads or anchor bolts between the unit and the foundation.
5. The shell of the generator set must have reliable protective grounding. For generators that require a neutral point to be directly grounded, the neutral grounding should be done by professionals and equipped with lightning protection devices. It is prohibited to use commercial food. The electrical grounding device conducts the neutral pointto be directly earthed.
6. The two-way switch between generator and mains must be very reliable to prevent reverse power transmission. The reliability of the two-way switch wiring must be inspected and approved by the local power supply department.
Paying attention to the above details can effectively avoid unnecessary damage to the equipment before use. Even if it is damaged, subsequent use can be carried out normally, which plays a certain preventive role in case of damage and corrosion.
