Adjustment Method of Cummins Diesel Generator Automatic Regulator

Jan. 05, 2023

In the process of using Cummins diesel generator automatic regulator, due to the constraints of the cooling system structure, changes in operating load and speed, changes in ambient temperature and other factors, the operating temperature of Cummins diesel generator has been greatly changed. Practice shows that it is most advantageous to control the temperature of cooling water at 75-85 ℃ and the temperature of lubricating oil at 75-95 ℃.

The adjustment of the active regulator of the brushless Cummins diesel generator mainly includes the adjustment of the closing voltage and the adjustment of the voltage regulating value. The two adjustment methods are different. The following is the introduction of the active adjustment methods of the Cummins diesel generator manufacturer.


Adjustment of closing voltage: connect a dry battery, storage battery and ammeter in series. Start the generator and gradually increase the speed. Observe the pointer of the ammeter on the generator when the contact of the interceptor is closed. If the pointer of the ammeter swings towards "+" and leaks, the closing voltage is high, and the tension of the tension spring should be weakened; If the pointer of the ammeter swings towards "-", the leakage indicates that the closing voltage is low, and the tension of the tension spring should be increased. Repeat the adjustment until the ammeter pointer almost does not swing when the contact of the interceptor is closed, then the leakage indicates that the closing voltage is appropriate.


Adjustment of voltage regulating value: use two dry cells in series with storage battery and ammeter. Start the engine and gradually increase the speed. When the voltage regulator works, observe the pointer of the ammeter. If the pointer of the ammeter swings towards "+" and leaks, it indicates that the voltage regulating value is high, and the tension of the tension spring should be reduced; If the pointer of the ammeter swings towards "-" and leaks, it indicates that the voltage regulating value is low, and the tension of the tension spring should be increased. Repeat the adjustment until the pointer of the ammeter almost does not swing when the voltage regulator works, so the leakage indicates that the voltage regulating value is appropriate.


The reason for this adjustment method is that the dry battery and the storage battery are connected in series and have a certain potential, while the Cummins diesel generator declares a certain voltage. When the two are not equal, current will occur. If the potential of the former is higher than that of the latter, the pointer of the ammeter tends to "-", and vice versa. As long as the potentials of the two are almost equal, the pointer of the ammeter will not swing.
