Diesel generator refers to diesel fuel, diesel engine as the prime mover driven generator power machinery, small volume, complete, convenient operation and maintenance, are often used in factories, enterprises, hospitals and other departments. But in the actual operation due to some reasons occasionally output voltage instability phenomenon, the following to introduce this phenomenon of several main reasons.
1, generator overload operation, load on large appliances caused by voltage fluctuation of frequent starting of large. .
2, the generator itself exists adverse factors, poor contact excitation voltage instability or brush, can check the specific excitation windings and excitation power components, including rectifier.
3, diode and thyristor and other resistor, adjustable potentiometer will often contact is not good, should pay attention to maintenance.
4, but also may be due to reasons of diesel engine speed instability, it is automatically according to the load weight to adjust the output power, fuel supply and stable high pressure oil pump speed caused more.
Therefore, in order to ensure the quality and stability of the power transmission effectively, ensure the smooth development of the project, the user must regularly check the maintenance of diesel engine. When abnormal situation, do not force start, should be a professional staff operating inspection, timely troubleshooting.
