1. If the alternator overheats for a long time, the generator will generate insufficient voltage or produce no electricity. When the generator is running, it feels hot when you touch it with your hands. There is obvious oil spattering from the bearings and you may smell a burning smell, which means the generator is overheated. Reasons for generator overheating: short circuit of the generator coil or long-term short circuit of the external conductor; lack of grease or rotor end play; friction of rotor and iron core; 2. The diagnosis and troubleshooting methods for generator overheating faults are as follows: 1) If you use a screwdriver on the generator case and feel vibration, and there is abnormal noise during the operation of the generator generator, this indicates that the generator bearings are loose. or the armature is in contact with the magnetic poles. Doit be fixed. 2) If the ammeter indicates insufficient charge, this indicates that the commutator or armature coil is shorted and needs to be repaired. 3) If the engine temperature is too high, the fan drive belt is too tight, or the governor current limit is too high, this will also cause the generator to overheat. 4) Check the grease in the generator bearings regularly and replace the grease if necessary. 5) When repairing the generator, the space between the rotor and the iron core should be ensured. If the gap is too large, the light will be dim, while if the gap is too small, it will cause friction and overheating. Axial play must not exceed 0.7 mm. 3. If the generator is found to be fried and fails, the generator must be repaired or replaced.
The same points:
1. They all have to absorb thermal energy from the outside. The thermal driving energy used byr Stirling engine is pressurized hot air at high temperature generated from outside. heating; Steam engines use high temperature and high pressure steam generated by external heating as thermal energy.
Differences:
1. The thermal energy used is different (one is high-temperature pressurized hot air generated by external heating; the other is high-temperature, high-pressure steam). generated by external heating) )
2. The Stirling engine has a simple structure, while the steam engine has a complex structure.
3. Due to different driving temperatures, the usage environment varies greatly.
4. The driving energy generation temperature is different. The Stirling engine can be driven to do work with a little thermal energy, so it can be used as a small power generation mechanism.
