Diesel generator sets have gradually attracted people’s attention as reliable backup power equipment, and are widely used in all aspects of national economic life, especially in some areas with insufficient power supply, diesel generator sets play a more important role. So what are the starting principles and conditions of diesel generator sets?
First, the principle of diesel generator set start
The starting process of diesel generator sets is relatively complicated. In the process of starting, there are various energy conversions. The corresponding starting principle of diesel generator sets is also very complicated, but it is not difficult to understand. At present, the starting method of diesel generator sets is generally electric starting, which includes the starting of the mechanical part and the stable output of three-phase voltage. The starting principle is as follows:
2. Conditions for diesel generator set to start
In order to operate normally, the diesel generator set must realize the conversion from thermal energy to mechanical energy, so that the diesel engine can change from a static state to a continuous operation state. To complete this process, some specific conditions are required. We will briefly describe it below.
1) The mixed gas should have a suitable amount of air and a sufficiently high temperature. This is the key to ensuring that the diesel engine can start normally, and it is also the key to improving fuel efficiency.
2) The crankshaft of the diesel engine should reach a certain speed. In order to burn the fuel and obtain high-quality heat energy, there must be enough rotation speed, which can increase the temperature of the combustion chamber, thereby obtaining more heat energy and ensuring the continuous operation of the diesel engine.
3) The starting torque must be large enough. Diesel engine starting needs to overcome a lot of resistance, especially friction, so it must have a large enough torque.
