Common reasons and solutions for generator failure to produce electricity:
1. Cause: Wiring error.
Treatment: Check and correct according to the wiring diagram.
2. Reason: The speed is too low.
Processing: Measure the rotation speed and keep it at the nominal value.
3. Cause: There is mud or oxide on the wiring joint between the stator winding and the generator power distribution equipment, the wiring screws are loose, the connection wire is broken and the stator winding is broken.
Treatment: Use a multimeter or light test method to find out where the disconnection is. Check the connection and contact of each wiring screw.
4. Cause: The field circuit is disconnected or has poor contact.
Treatment: Use a multimeter to find out where the broken wire is, re-solder the broken wire firmly and wrap it for isoler.
Detailed information1: Under normal circumstances, due to the influence of high-order harmonics or manufacturing processes, the air gap under each magnetic pole is uneven and the magnetic potential is uneven , which results in very low voltage. If the voltage is between one and several volts, it is not dangerous and there is no need to handle it.
2: The generator winding has a short circuit or poor insulation to the ground, which causes the performance of the electrical equipment and generator to deteriorate and easily generate heat. It must be repaired in time to avoid expansion. the accident.
3: There is no voltage between the neutral line and ground when there is no load, but voltage appears when there is a load. This is due to the imbalance of the three phases. the load must be adjusted to make it fundamentally balanced.
The current of ggenerator is too large
1: The load is too high, the load must be reduced.
2: If a phase short circuit or ground fault occurs in the transmission line, the line should be inspected and restored to normal after the fault is cleared.
There are many reasons that can cause the above failures: 1. The generator belt is loose, check and adjust the belt tightness and replace it if necessary. 2. The engine idle speed is too low (especially for diesel vehicles) and cannot reach the generator's rated speed. Adjust engine idle speed appropriately. 3. When large electrical appliances are turned on (headlights, air conditioners, electric heaters, etc.), power generation cannot be obtained even when the engine speed is low. 4. If the generator coil or motorcycle regulator is damaged, especially if the generator is older, the magnets will be demagnetized. 5. The circuit connector is loose or oxidized.
Clogged engine injectors, leaking oil lines, reduced fuel pump power, and clogged fuel filters will all lead to vehicle weakness. The throttle valve and other components are clogged or have problems, resulting in insufficient air intake or poor ignition of spark plugs, etc., which will cause the car to refuel slowly and accelerate.
1. The engine oil system is a common problem in cars. Clogged fuel injectors, leaking oil lines, reduced fuel pump power, and blocked fuel filters will prevent the car from going uphill. The reason why the car feels powerless is mainly because the engine does not have enough oil when going uphill, the combustion efficiency decreases, and the power does notcannot meet our needs.
2. The same goes for the air intake system. In addition to oil, the engine also needs air if the air filter, throttle valve, and other components are clogged or have problems, resulting in insufficient air intake. , it will also cause the car to malfunction. The speed is slow.
3. The spark plug is also the source of common faults. If the spark plug fires poorly, it can cause a poor acceleration problem.
4. If the car seems dull and the steering wheel or car body visibly shakes when it stops, this indicates that at least one cylinder in the car's engine is not working properly or is stalling. Under normal circumstances, if one cylinder of a four-cylinder engine fails to start, the engine can still run. As the number of cylinders increases, this symptom becomes more difficult to detectcter.
5. If you turn on the air conditioner in summer, small engine vehicles will have difficulty accelerating and their fuel consumption will increase significantly. Indeed, the air conditioner must drive the compressor. it works and the compressor has to The power is very large and the motor has to bear such a large internal friction, so it is inevitable that the speed is slow and the acceleration is small.
