(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.

Diesel Generator misuse can seriously affect the service life of Diesel Generator sets, let’s look at the daily life of Diesel Generator sets error mode of operation what?

Operation of a Diesel Generator Error: diesel engine oil is insufficient operational

At this point a result of shortage of oil supplies caused by the friction pair surface oil supply shortage, leading to abnormal wear and tear or burn. To this end, Diesel Generators and diesel operation before starting the process to ensure that sufficient oil to prevent the pull-cylinder caused due to short of oil, bush-burning failures.

Operation of two Diesel Generators Error: emergency shutdown with a load or shut down immediately after the sudden load dismount

Diesel Generators after the flame to stop the cycle of water cooling system, heat capacity sharply reduced loss of heat cooling parts, could easily lead to cylinder head, cylinder cover, cylinder block and other parts overheat, resulting in cracks, or to over-expansion of the piston stuck in the cylinder inside. On the other hand, Diesel Generator shutdown cooling without the idle will lead to friction surface oil shortage, when the diesel engine starts again, a result of wear and tear aggravated by poor lubrication. Therefore, Diesel Generators before flameout removable load, and gradually reduce the speed, no-load running a few minutes.

Diesel Generators misuse 3: After the cold start, warm-up on the tape does not load operation

Diesel Generator cooler to start, due to oil viscosity, poor mobility, is the lack of oil pump oil, machinery lubrication friction surface due to adverse short of oil, resulting in rapid wear and tear, or even pull cylinder, bush-burning and other failures. Therefore, the diesel engine should idle operation after the cooling starts to heat up, stand-by oil temperature reaches above 40 ℃ and then with a load operation; machines started to be hanging low gear, and orderly travel for a distance in each gear until the oil temperature normal, oil supply sufficient , before it is converted to a normal driving.

Operation of four Diesel Generator Error: diesel cold start throttle after Meng Hong

If Menghong throttle, then a sharp increase in Diesel Generator speed will cause the plane generated some friction surface due to severe dry friction wear. In addition, the H-throttle when the piston, connecting rod and crankshaft receiving power changes, caused by severe impact, easy to damage parts.

Diesel Generators misuse 5: The lack of cooling water or cooling water, oil temperature is too high in case of operation

Diesel Generator cooling water shortage will reduce its cooling effect, diesel engine due to lack of effective cooling and overheating; cooling water, oil the oil temperature is too high, can cause engine overheating. At this point diesel cylinder head, cylinder liner, piston components and valve and other major heat load of large, its mechanical properties such as strength, toughness, and so a sharp decline, so that part deformation increased, decreased with the gap between the parts to speed up parts wear and tear, so serious that it cracks, stuck mechanical failures. Diesel Generator diesel engine combustion process overheating going to get worse, so that the work of injector disorders, atomized poor, increased carbon deposition.
