Handling common problems of synchronous generators

The diesel engine is working normally, but the generator fails to generate electricity or the voltage is very low. This may be due to the components associated with the generator, such as: the exciter is damaged, and the excitation voltage cannot be supplied. The excitation current is taken in. The residual magnetism of the rotor is weakened or declining, which will make the generator unable to generate electricity or the transmission voltage is extremely low.

The right to respond usually includes: using an appropriate DC voltage and polarity, directly connected to the excitation winding to magnetize. Carefully inspect the exciter and the cyclotron rectifier, find abnormal components or windings, and replace them for restoration.

The transmission voltage of the generator is unstable, and the belt voltage is poor, and the transmission voltage drops very fiercely. Usually, the automatic voltage regulator (AVR), the excitation generator and the gyro rectifier are faulty, which is the primary cause of this phenomenon. The negative feedback transfer function of the load change is invalid, and the components of the gyro rectifier department and the components of the excitation generator voltage setting circuit are damaged.Abnormalities in that area will cause the transmission voltage to be unstable.

The actions to be adopted are: focus on surveying the AVR, and use the imitation test method to check whether its sensitivity and transmission linearity are in line with the factory standard, and if there is an abnormality, it will be repaired. There are not many components of the circuit related to the cyclotron rectifier and the excitation generator. The first is the rectifier element and potentiometer. If there is damage, change it in real time.

This may be due to the components associated with the generator, such as: the exciter is damaged, and the excitation voltage cannot be supplied. The excitation current is taken in. The rotor's dead center residual magnetism is weakened or declining. It will make the generator unable to generate electricity or the transmission voltage is extremely low. The right to respond is usually: use an appropriate DC voltage and directly connect to the excitation winding according to the polarity Magnetization.

    Before starting, you should check whether the fuel volume of the fuel tank is rich, and there is no oil leakage in each oil pipe and the discussion area; whether the cooling system water is rich, clean and leak-free, and whether the fan belt is tight or not. The internal combustion engine and generator drive parts should be connected and trusted. The wires of the input line are well-insulated, complete and effective in all aspects. After starting, it should run at low speed for 3 to 5 minutes. After the temperature and oil pressure wheel are normal, the initial work can be done. The generator should be no different in the speed increase. Ring, the slip ring and commutator are well brushed, no jumping and sparking phenomenon. After the operation is stable and the frequency and voltage reach the rated value, power can be supplied to the outside.

    Blue smoke, fire reason: It means that the engine is burning oil. There are three types of reasons: first, the piston ring goes opposite, and the oil comes in the cylinder; the second is the oil level of the oil pan of the atmosphere filter, which leads the ring. The height of the groove; Third, the gap between the duct and the valve stem is too poor. Expulsion idea: Adjust the piston ring so that the opening teeth of the ring are staggered 120 degrees or 180 degrees, and the opening teeth of the ring should avoid the piston pin hole and the side pressure is poor. Adjust the height of the oil level of the oil filter of the atmosphere filter below the height of the annular groove; if the clearance between the duct and the valve stem is too poor, replace the component and reduce the clearance. The normal mutual assistance clearance between the two is 0.0

    In the power generation industry in China, we have been working hard, pursuing the concept of quality and service, and for the sake of customers, the full power generator chooses China and your generator is a professional housekeeper. At present, the diesel generator set maintenance market refers to damage inspection and routine maintenance. Two aspects: after maintenance refers to the failure of the diesel generator, there are problems with various accessories, such as replacing the generator or
