1. Principle of Diesel Generator: Diesel engine drives the generator to operate and convert diesel energy into electrical energy.
In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high pressure atomized diesel fuel injected by the injector. Under the upward pressure of the piston, the volume decreases and the volume decreases. the temperature rises quickly, reaching the ignition point of diesel. Diesel ignites, the gas mixture burns violently, rapidly expands in volume and pushes the piston down, which is called "work".
2. Gasoline Generator: The gasoline engine runs the generator, converting gasoline energy into electrical energy.
In the cylinder of the gasoline engine, the mixed gas burns violently, expands rapidly in volume, and pushes the piston down to do work. Whether it is a diesel generator or an gasoline generator, each cylinder performs work in a certain order. The thrust acting on the piston becomes the force that causes the crankshaft to rotate through the connecting rod, thereby causing the crankshaft to rotate.
By installing the brushless synchronous alternator coaxially to the crankshaft of the electric machine, the rotation of the electric machine can be used to drive the generator rotor. Using the principle of "electromagnetic induction", the generator. will produce an induced electromotive force. The charging circuit can generate current.
Detailed information:
Getting started:
1 . For units stopped for more than 24 hours, the test valve must first be opened and the oil pump must be started. For units shut down for more than 7 days, the insulation resistance of the exciter and operating circuit must be measured andmust meet the requirements.
2. Start the fuel pump, release the air into the pipeline and observe whether the voltage is within the specified range. If it is normal, it can be officially launched.
3. Check whether the voltage of the starting power supply meets the requirements. If the voltage is normal, press the start button and release it after the diesel engine has run normally.
4. Once the diesel engine is running, observe the value indicated on the oil pressure gauge. When it exceeds the specified value, stop the oil pump, close the scavenge pump drain valve and tighten the front. clutch screw.
5. When the generator starts, it is considered that the generator and all electrical equipment are charged and the human body is not allowed to touch the live parts.
6. After starting the generator, the speed of the diesel engine should be gradually increased and uNo inspection should be carried out before power transmission.
7. Gradually adjust the speed of the diesel engine, but when adjusting, pay attention to whether the generator is operating normally. Under normal conditions, the slip ring and commutator brushes should not exhibit any abnormal beating, sparking or noise.
8. Adjust the generator output voltage and frequency. The voltage value should be stable and reach 380V+-10V, and the frequency should reach 50Hz+-0.5Hz.
