Daily maintenance of the power supply means checking the amount of cooling water and lubricating oil after use and use, and refilling them in time if they are insufficient. Replace the oil, oil filter and air filter regularly. The tank should also be kept clean. Do not mix the sediment to avoid blockage of the oil circuit, artificial wear of the oil pump piston and blockage of the fuel injector. This is a diesel engine. Most gasoline engines have blocked pipes (electronic injection gasoline). motors are generally not used in generators)
There is basically no problem with the generator As long as it is not overloaded there is usually no major problem for generators that have not been used for a long time. will lose magnetism. If you charge it with a DC battery, you'll be fine. If the voltagedoes not reach rated voltage during use, this is usually due to excitation. Open the circuit and check if the circuit and silicon rectifier are intact. .
Steam turbine generators are generally hidden pole machines, 3000 rpm; other generators are generally salient pole machines, 3000/2p rpm. From the generator's perspective alone, the hidden-pole generator spins faster (because there is no need to remove it). Note that generally salient pole machines are equipped with a reduction gear at the front, so the shaft connected to the generator rotates very quickly, but the generator rotates very slowly.
Back to the main question. Thermal power plants have both salient pole machines and hidden pole machines. . . So what do you want to express?
