Gasoline Generator

Troubleshooting
One can not generate electricity

(1) The circuit diagram by wiring error check and correct.
(2) The main Gasoline Generator or exciter excitation winding pick the wrong, resulting in wrong polarity. Often occurs after the replacement field winding caused by wiring errors. Should be checked and corrected.
(3) The rotating rectifier component breakdown short circuit, the pros and cons to both turn-on. Check with the multimeter to the resistance of the positive and negative rectifier element, replace damaged components.
(4) Main Gasoline Generator field winding disconnected. Measured with the multimeter check the main Gasoline Generator excitation winding, the resistance is infinitely great and should be connected to excitation line.
(5) Main Gasoline Generator or exciter winding has serious short-circuit the armature winding short-circuit, generally there are clear signs of overheating, excitation winding short circuit resistance value can be judged by its tributaries. Replacement of damaged windings.
2, no-load voltage is too low (for example: line voltage of 100 volts or so)
(1) exciter field winding disconnected. Check exciter field winding resistance should be infinity. Replacing broken or connected to the coil loop coil.
(2) The main Gasoline Generator field winding serious short-circuit. Exciter field winding current is large. Main Gasoline Generator field winding severe fever, shock increased, excitation winding tributary of the resistance much smaller than the normal value. Replacement of short-circuit coil.
(3) Automatic voltage regulator failure. Rated speed, the measured output tributary of the automatic voltage regulator and the motor current value is equal to the factory no-load characteristics. Maintenance of automatic voltage regulator.
3, no-load voltage is too high
(1) Automatic voltage regulator out of control. No-load exciter field winding current is too large. Check automatic voltage regulator.
(2) The tuning voltage is too high, re-tuning voltage.
4, exciter excitation current is too large
(1) The rectification element has one or two components do not pass to the pros and cons of open circuit, with multimeter checks, replace the damaged components.
(2) The main Gasoline Generator or exciter field winding part of the short-circuit, measure the DC resistance of the coil of each pole. Replace the coil short-circuit fault.

5, steady-state voltage regulation rate differential automatic voltage regulator is faulty checks and troubleshooting.
6, vibration
(1) and the original motivation for bad check and correct docking docking. After tightening the bolts to ensure Gasoline Generator with the original motivation for the axis of the straight and concentric.
(2) The rotor balancing is not good, took place in the rotor rewind, they should look for is balancing.
(3) The main part of the Gasoline Generator field winding DC resistance of each pole short-circuit test to identify short-circuit point of failure. Replace the coils.
(4), bearing damage, are generally overheated bearing caps, replacement bearings.
(5) The original motivation failure, check the prime mover.
7, overheating
(1) Gasoline Generator overload, so that the load current, voltage does not exceed rated.
(2) The load power factor is too low, adjust the load, so that no more than rated excitation current.
(3) Speed is too low, adjusting speed to the rating.
(4) Gasoline Generator winding, some of a short circuit, short circuit to identify, correct or replace the coil.
(5) Ventilation duct obstruction, remove obstructions, open the motor, the air duct a thorough winds.
8, bearing overheating
(1) a long time after use of excessive bearing wear, replace bearings.
(2) The poor quality of lubricant grease. Mixed use of different brands of grease. Grease inside of impurities. Loaded too much grease to remove the old grease, cleaning grease after new ones.
(3) and the original motivation for docking bad strictly right straight, looking for are concentric.
