Reasons for Low Backup Power Supply Voltage of Diesel Generator Sets

What do you think is the reason for the low backup power supply voltage of Cummins diesel generator sets? The application of Cummins diesel generator sets has brought convenience to people's lives, but there are still some problems in use. Below, the editor will share with you the reason for the low backup power supply voltage of Cummins diesel generator sets, including the low speed of the prime mover. The process is to adjust the speed of the prime mover to the rated value. If the resistance of the excitation circuit is too high, the treatment will reduce the resistance of the field rheostat to increase the excitation current. For semiconductor excitation diesel generator sets, it is necessary to check whether the additional winding joints are disconnected or connected incorrectly.

The exciter brush is not in the neutral position, which may cause handling issues or low spring pressure. Adjust the brush to the correct position, replace the brush, and adjust the spring pressure. Some rectifier diodes have been broken down, and the task is to inspect and replace the broken diodes. If there is a short circuit or grounding fault in the stator winding or excitation winding, the solution is to check the fault and remove it. The contact surface of the electric brush is too small, the pressure is insufficient, and the contact is poor. If it is caused by the uneven surface of the commutator, it can be polished with sandcloth at low speed, or the spring pressure can be adjusted.


Since 1982, Dingbo Generator has been a generator set manufacturer qualified by the "National Internal Combustion Engine Quality Supervision and Inspection Center". The product quality has passed the IS09001 quality system standard certification. And obtained the qualification certificate for self-operated import and export. Over the years, Dingbo units have been widely used in all walks of life, and have won the network access qualification of the Ministry of Information Industry, the network access qualification of the Ministry of Radio and Television, the network access qualification of CNPC, the network access qualification of China Mobile, and the manufacturing qualification of marine units. In 2016, Dingbo was awarded the Certificate of Qualified Supplier of China Nuclear Power Group. Dingbo Generator has been cooperating with Shangchai Power for many years. In 2009, it became the OEM partner of Shangchai Power in China. Dingbo generator VOLVO unit ranks the top three in the Asia-Pacific sales volume, and is the core OEM partner of Sweden Volvo in the Asia-Pacific region.

What Is the Difference Between Electric Motor and Electric Generator

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and winding currents to generate force. In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction. An electric generator operates in the reverse direction, converting mechanical energy into electrical energy. Electric generator can be divided into various type, open type, silent type, trailer type, portable type and container type, etc. Electric generator is mainly composed of diesel engine & alternator. Electric generator set is mainly composed of engine, alternator, control module, and common base. Electric generator :- Electric generator is a type of machine which converts mechanical input (energy) into electrical output (...

Engine Fault Code Messages - Volvo Penta Engine

Volvo Penta Engine Fault Code When a malfunction has occurred and the diagnostic system has generated one or more fault codes, these are read out differently depending on the equipment used. Please refer to “Fault code messages”. If the system indicates that a fault code has been set: 1 Cut engine speed to idle, or shut the Volvo engine off. 2 For DCU/DU Read the fault code from the display, please refer to Reading fault codes via the DCU or Reading fault codes via the DU. For CIU press the diagnostic button and read the fault code, by observing the flashing of the diagnostic lamp. Refer to Reading fault codes via the diagnostic lamp, CIU. 3 Look up the fault code in the Fault Code Register chapter and take the recommended measures. Reading fault codes via the DU (Display Unit) Depending on the severity of the fault the text, either WARNING! or ALARM STOP (a buzzer sounds) will be shown on the display 1 Press any button to come to the fault list. The f...
