Possible malfunctions of the generator and ways of their elimination
|
|
|
Cause of defect
|
Way of elimination
|
|
During the operation of the engine on average turns of the shooter of the index of tension shows voltage below 12 V
|
|
|
The driving belt is poorly tense
|
To pull a driving belt
|
|
Tension regulator, brush knot or winding of excitement (at inclusion of ignition the control lamp in a combination of devices does not burn) is faulty
|
To check serviceability (see <repair of the generator>)
|
|
Jamming of brushes in channels of the brush holder
|
To clear brushes and the brush holder of dust and dirt
|
|
Podgoraniye, oxidation go wear of contact rings of a rotor
|
To smooth out or pierce contact rings (see <repair of the generator>)
|
|
Break of a winding of excitement
|
To check, if necessary to replace (see <repair of the generator>)
|
|
The vypryamitelny block is faulty
|
The faulty block to replace (see <repair of the generator>)
|
|
Break or mezhvitkovy short circuit in windings of the stator or a rotor
|
The stator or rotor with the damaged windings to replace (see <repair of the generator>)
|
|
The index of tension shows voltage over 16 V
|
|
|
Tension regulator is faulty
|
To check tension regulator. On the plug <V> and <-> the generator to connect the voltmeter on 30 V of a class 0,5-1. To start the engine, to establish the frequency of rotation of the engine on a tachometer within 1000-1200 min.-1. To turn on the dimensional light to replace the indication of the control voltmeter. Tension has to be in limits 13,5-14,2 B, at a temperature of generator of 25+5 °C. If tension does not keep within the specified limits, to replace tension regulator
|
|
The increased noise during the operation of the generator
|
|
|
Zadevaniye of a rotor for a stator pole
|
The faulty bearing or the plastic holder of the bearing in a cover to replace (see <repair of the generator>)
|
|
Weakening of coupling screws of covers of the generator
|
To tighten the screw with the moment of 0,5-0,6 kgfs · m
|
|
Jamming of bearings
|
Faulty bearings to replace (see <repair of the generator>)
|
|
Development of a seat under the bearing from brush knot
|
If necessary to replace the plastic holder of the bearing (see <repair of the generator>)
