How to maintain lubricating oil system of diesel genset

We should pay attention to some points when maintaining lubricating system of diesel generator set, as follow:
1.Select suitable diesel oil
In generally, every diesel engine manual has specific the type of lubricating oil use. If you can't buy the lubricating oil specified in the manual, you can choose the similar brand lubricating oil. Never mix different brand lubricating oil.
2.Often check the quality of diesel oil during the use
Check the mechanical impurities in the oil and check the oil scale in the heat engine time. If there are small particles on the scale or the marking on the oil scale cannot be seen clearly, it means that there are too many impurities in the oil, the oil shall be changed and the oil filter shall be cleaned.
Check oil viscosity. It is commonly used to twist the engine oil on the fingers. If there is viscosity feeling and stretching phenomenon, it indicates that the viscosity of the engine oil is appropriate, otherwise, it indicates that the viscosity of the engine oil is not enough. The accurate inspection method is to use viscometer to measure.
3.Suitable capacity of diesel oil.
Before opening diesel engine, we should check the oil level every time to ensure that the oil level is within the specified range. It is easy to cause tile burning and cylinder pulling if over low oil level, we should fill diesel oil in time to ensure oil level on the specific range. When oil level is over high, it is easy to cause cause the engine oil to run into the cylinder, the combustion chamber to deposit carbon, the piston ring to stick, and the exhaust gas to emit blue smoke. At this time, check whether there is water and fuel leakage in the engine oil, find out the cause, remove and change the engine oil.
4.Suitable oil pressure
Each type of diesel engine has its own specified oil pressure. When the engine is started to rated speed or medium speed, the oil pressure shall rise to the specified value within one minute, otherwise, the cause shall be found out. 4105, 4135 and other generator sets are equipped with pressure regulating screws, which rotate anticlockwise to reduce the oil pressure and clockwise to increase the oil pressure.
5.Clean lubricating system and change oil regularly
The oil filter shall be cleaned regularly; the oil basin and oil passage shall be cleaned when changing the oil.
Cleaning method:
When heating the engine, drain diesel oil, so as to remove the impurities in the engine oil basin, oil passage and oil filter as much as possible. Replay the mixed oil (15% ~ 20% kerosene, or mix according to the proportion of diesel oil: oil = 9:1) in the oil basin. Its quantity is 60%~70% of lubricating oil, run the diesel engine at low speed for 5 to 8 minutes (the oil pressure is above 0.5kgf/cm2), stop the engine, drain the mixed oil, clean the oil filter, filter screen, oil radiator and crankcase, and add new oil.

How to Read Alarm Codes From SmartGen Genset Controller

Auto Module Control Panel is the configuration for nobody on duty controlling generators. This kind of panel adopts auto module control system, with large LCD display to show the menu, such as SmartGen controller. Features:   1. SmartGen 6110 can receive remote output signal from ATS and realize auto start and stop of generators. 2. SmartGen 6310 can realize all functions of 6110, add RS232 interface which can communicate with PC to realize remote operation.  3. SmartGen 6410 Auto Mains Failure controller, can realize all functions of 6310, furthermore can detect  ATS and control directly. The alarm of diesel generator controller is not the amount of stop alarm, which does not affect the normal operation of diesel generator. When the alarm occurs, the unit will not stop, and when the alarm conditions do not exist, the amount of warning will automatically disappear.  Today Starlight manufacturer mainly shares alarm codes for diesel generato...

How Do You Check Diesel Consumption In The Diesel Generator Set?

  Diesel generator sets   are crucial assets in various industries, providing backup power during outages or serving as primary power sources in remote locations. With fuel costs being a significant operational expense, monitoring diesel consumption becomes essential for efficiency and cost-effectiveness. Here's a comprehensive guide on how to effectively check diesel consumption in a generator set. Understanding Diesel Consumption Metrics Before delving into the monitoring process, it's crucial to grasp the key metrics associated with diesel consumption: Fuel Consumption Rate: This indicates the rate at which diesel is being consumed by the generator set, typically measured in liters per hour (L/hr) or gallons per hour (GPH). Load Factor: The percentage of the generator's maximum capacity being utilized at any given time. It directly influences fuel consumption, with higher loads resulting in increased fuel usage. Fuel Efficiency: A measure of how effectively the generator...
