Análisis del grupo electrógeno diesel Cummins que funciona con inestabilidad

1. La potencia de salida real del generador durante el funcionamiento estará sujeta al contador de potencia o al amperímetro.?
Respuesta: El amperímetro prevalece, y el medidor de potencia es solo para referencia. Corriente = potencia ×1.8

2. La frecuencia y el voltaje de un grupo electrógeno son inestables. El problema radica en el motor diesel o generador?
Respuesta: Motor diésel.

3. La frecuencia de un grupo electrógeno es estable y el voltaje es inestable. El problema radica en el motor diesel o generador?
Respuesta: Es el generador.

4. El voltaje y la frecuencia de un grupo electrógeno con carga son estables, pero la corriente es inestable. ¿Cuál es el problema??
Un: El problema es que la carga del cliente es inestable.

5. The frequency of a generator set is unstable. What is the main problem?
Respuesta: The main problem is that the speed of the generator is not stable, Es decir, the user’s load is not stable.

6, generator loss of magnetism is how to deal with?
Respuesta: The generator is not used for a long time, resulting in the loss of the residual magnetic field contained in the iron core before leaving the factory, the excitation coil can not establish the due magnetic field, then the generator runs normally but can not produce electricity. This kind of phenomenon new machine, or long – term use of the unit is more, the treatment method has

(1) Press the excitation button if there is an excitation button;

(2) If there is no excitation button, magnetize it with battery;

(3) With a light bulb load, overspeed for a few seconds.

7. After a period of time, the generator set is found to be normal but the power is decreased. What is the main reason?
Respuesta: (1) the air filter is too dirty, the air is not enough, then we must clean or replace the air filter;
(2) The fuel filter device is too dirty, the injection amount is not enough, it must be cleaned or replaced;
(3) the ignition time is not correct, must be adjusted.

8. In the use of diesel generator sets, what are the most important and must be paid attention to?
Respuesta: (1) The water in the tank must be sufficient and kept in the allowable temperature range;
(2) lubricating oil must be in place, but not excessive, and keep working within the allowable pressure range;
(3) The frequency is stable at about 50HZ and the voltage is stable at about 400V;
(4) The three-phase current is within the rated range.

9. Which parts and components do diesel generator sets need to be cleaned or replaced regularly?
Respuesta: filtro diesel, air filter and oil filter (individual units and water filter).
