Starlight generator

Longer than 10 minutes of low idle speed or no load can damage the engine. Because the temperature of the combustion is so low that the fuel can not be completely burned. This will cause the formation of carbon deposition and valve adhesion around injector holes and piston rings. If the engine coolant temperature is below 60 ° C, the unburned fuel will wash away the lubricating oil on the cylinder wall and dilute the oil in the crankcase. Fuel diluents will affect the quality of lubricant and shorten the engine life. It ’ s better to shorten idle time to prevent this from happening. Running diesel generator set under small load, with the continuation of running time, the following five hazards will occur. 1. Piston-cylinder liner seal is not good, oil channelling, entering to the combustion chamber to burn, exhaust blue smoke; 2. For turbocharged diesel engine, supercharging pressure is low due to low load and no-load. It is easy to cause the effect of turbocharger ...

The following is safety procedures: 1. The diesel engine-powered generator, the operation of engine section is carried out in accordance with the relevant regulations of the internal combustion engine. 2. Before starting the generator, it is necessary to carefully check whether the wiring of each part is correct, whether the joint parts are firm, whether the brush is normal, whether the pressure meets the requirements, and whether the grounding wire is good. 3. Before starting, put the resistance of the field varistor at the maximum position, disconnect the output switch, and the  generator set  with the clutch should disengage the clutch. Start the diesel engine with no load, and then start the generator after running smoothly. 4. After the generator starts running, always pay attention to whether there is mechanical noise or abnormal vibration. After confirming that the situation is normal, adjust the generator to the rated speed, adjust the volt...

The function and type of diesel generator set governor 1. The function of the governor of diesel generator set The function of the governor is to adjust the fuel supply automatically with the change of the external load of the diesel engine within the required speed range of the diesel engine, so as to keep the diesel engine speed basically stable. When the diesel engine drives other working machinery (such as generator, pump, etc.), if the output torque is equal to the torque (drag moment) required by the working machinery to overcome the working resistance, then the engine is in a stable state (the rotational speed is basically stable). If the resistance moment exceeds the output torque, the speed of the diesel engine will decrease, and the diesel engine will stop working. When the output torque is greater than the resistance moment, the rotational speed will increase, if the new balance is not reached, the rotational speed will continue to rise and the ...

Summary of System Design The following points must be given extra thorough consideration when designing a cooling system: • The maximum ambient temperature the engine must operate in. • Cooling air flow direction, i.e. if a puller or pusher fan is to be used. A pusher fan is recommended for generator sets to avoid generator overheating. On mobile applications, consideration must be give to any slipstream. • Engine heat radiation causes a rise in cooling air temperature in pusher fan systems. • Generator heat contribution is 7-10 % of net engine power. • Additional coolers in front of the radiator (puller fan) or behind the radiator (pusher fan) will cause a rise in cooling air temperature and a reduction in airflow. • The radiator may become clogged in dusty environments, which will impair cooling capacity. The radiator must be installed so that it can easily be cleaned. Grilles / filters are available as options. • There must be ...
