What are the problems in the installation and use of diesel generators?

During the start-up operation of diesel generator sets, especially in winter, there is very little oil on the piston rings and cylinder walls, the sealing effect is not good, and the phenomenon of repeated startup and failure to run on fire may occur. Diesel generator sets sometimes severely affect the sealing performance of the cylinder due to heavy cylinder wear, making startup more difficult. To this end, the injector can be removed, and 30 to 40 ml of engine oil can be added to each cylinder to enhance the sealing performance of the cylinder and increase the pressure during compression.

Self-protection function of diesel generator:

       Various sensors are installed on diesel engines and alternators, such as water temperature sensors and oil pressure sensors. Through these sensors, the operating status of the diesel engine is displayed intuitively to the operator, and with these sensors, an upper limit can be set. When the limit value is reached or exceeded, the control system will give an alarm in advance. At this time, if the operator fails to take measures, the control system will automatically stop the unit. The diesel generator set adopts this method to protect itself.

Diesel generators:

       The sensor plays the role of receiving and feeding back various information. It is the control system of the diesel generator that really displays these data and performs the protection function.

What are the noise sources of diesel generators?

1.Intake noise, exhaust noise and cooling fan noise

2. Combustion chamber working combustion noise, mechanical noise of engine parts friction

3.Noise generated by the rotor rotating at high speed in the electromagnetic field

Winter diesel generator start tips:

Preheating: The cooling system can heat the water and heat the oil pan with a heat source.

Improving air tightness: The fuel injector can be removed, and 30-40ml of engine oil can be added to each cylinder to enhance the sealing performance of the cylinder and increase the pressure during compression.

Gearing: crank the crankshaft before starting to make it easy to run before starting.
