Cylinder flushing pad is a common fault in generator sets, and there are various forms of cylinder flushing pad, with the common feature being abnormal noise. Due to the varying degrees of impact on the cylinder cushion, the abnormal sound generated is also different. This article explains the troubleshooting methods based on the varying degrees of cylinder cushion faults in three Hongqi 120 bulldozer   generator sets . When a bulldozer is cold started, there are two knocking sounds of "dang" and "dang", and a white smoke is emitted first. The generator set catches fire only after black smoke is emitted. When suddenly increasing the throttle, there is also a knocking sound, and after the throttle stabilizes, the abnormal sound basically disappears. If there is still a knocking sound when suddenly increasing the throttle repeatedly. During the cylinder cutout inspection, it was found that the abnormal noise occurred in cylinder VI. Suspect that the fuel injector need...

How to deal with vibration reduction, noise reduction, and cooling of diesel generator sets? The noise of diesel generator sets mainly includes engine exhaust noise, intake noise, combustion noise, mechanical noise of moving parts of the generator during operation, and generator noise. So, how to deal with vibration reduction, noise reduction, and cooling of diesel generator sets? Firstly, for vibration reduction treatment, to reduce the noise caused by diesel generator set vibration, we choose shear type rubber isolation pads placed between the engine body and the concrete base, To eliminate the rigid connection between the   diesel generator set   and the foundation, thereby reducing the low-frequency noise generated by mechanical vibration of the equipment, the exhaust pipes are wrapped with asbestos. For noise reduction treatment, noise reduction measures are taken for the inlet and outlet of the diesel generator set, with 50mm thick rock wool pasted inside and fixed with ...

Regarding the phenomenon of the Volvo diesel generator battery not being charged and the solutions, first we need to check whether the connection of the charging circuit is reliable, check whether the connection and plug are in good contact, and carefully check whether the socket and plug have "ignition" or arc burning phenomenon, wireless circuit damage or wire breakage. Secondly, check if the  Volvo diesel generator  charger is damaged and if the charging parameters meet the requirements: the initial charging current reaches 1.6-2.5A per unit. The maximum charging voltage reaches 14.8-14.9V/unit, the floating charging conversion current reaches 0.3-0.4A/unit, and the floating charging voltage reaches 14.0-14.4V/unit. Check if there is any drying phenomenon inside the battery, that is, if the battery is severely out of liquid. The electrode plate should also be checked for irreversible sulfation. The irreversible sulfation of the electrode plate can be determined by meas...

The lubrication method for variable pitch reducers of generator sets is generally immersion lubrication and grease lubrication. After every 6 months of operation of the generator set, the oil quality should be checked as follows: observe the presence of water and emulsion in the oil; Check the viscosity of the oil, and if the difference exceeds 20% or decreases by 15% compared to the original, it indicates that the oil is ineffective; Check the insoluble content, which should not exceed 0.2%, and conduct an anti emulsification ability test to discover whether the oil has deteriorated; Check if the additive composition has decreased. If there are any problems, the oil should be changed or filtered. When changing the oil, the oil is discharged from the oil drain hole and then injected into the oil injection hole. When installing the plug, thread sealant should be applied to the thread. The lubrication system should be kept clean, and measures should be taken to prevent dust, moisture, an...

  During the use of the generator set, various faults occur due to its own factors or objective external conditions. In order for users to master the maintenance technology of the generator set, the generator manufacturer shares the maintenance technology of the cylinder head fault of the generator set that has been maintained for many years, hoping to give users some help in the maintenance of the cylinder head of the   diesel generator set . Some important maintenance methods for repairing generator cylinder head faults are summarized as follows: 1. If the generator set sleeps until it breaks through and leaks due to water shortage and high temperature, it is likely to cause cracks in the cylinder head valve seat ring, and the copper sleeve rubber ring of the fuel injector melts at high temperature. The cylinder head that produces the cracks should be scrapped and disposed of. 2. The copper sleeve and rubber ring of the fuel injector may be damaged after prolonged operation....

Once a diesel generator fails, it must be repaired before it can be put into production again. Careful working attitude and accurate fault analysis are necessary conditions for successful maintenance of diesel generator. However, in our daily maintenance work, some irregular work habits often lead to the failure of maintenance work. Here, Dingbo Power Generation Equipment lists some illegal working habits in the maintenance of diesel generator for our technicians to learn from. The specific content is shared as follows: 1. Unqualified cleaning of  generator parts During the maintenance of diesel generator, the correct removal of oil stains and impurities on the surface of parts is of great significance to improve the repair quality and extend the service life of machinery. If the sundries in the bolt hole and the sand in the hydraulic element are not completely removed, the bolt torque is insufficient, the piston ring is easy to break, t...

What are the benefits of performing air filter cleaning on diesel generator sets? Diesel generator sets are commonly used power supply equipment in daily life or production, and how to maintain the machine has become an important aspect. Many experienced technicians pay special attention to the cleaning of the air filter for diesel generator sets, and they often carry out such operations, which makes some unfamiliar people quite puzzled. Why do we need to clean the air filter of the diesel generator set? Below, the   diesel generator set manufacturer   will analyze it for everyone. In fact, the principle of air filter cleaning for diesel generator sets is very simple. For humans, we also need to frequently go to places with good air to absorb fresh air, which can achieve good comfort and improve our own lives. The same applies to some machinery and equipment. Many substances in the environment also pose significant hazards to the diesel generator set itself, requiring regular ...
