Diesel Generator Tech

The vibration of diesel generator may occur in use, so what is the cause? Below, we will briefly introduce Dingbo   Power Generation   Equipment to you. 1. Some imbalances in the transformation are mainly caused by the imbalance of the rotor, coupler, coupling, and transmission wheel (brake wheel). The solution is to first find the rotor balance. If there are large transmission wheels, brake wheels, couplers, and couplings, they should be separated from the rotor and balanced separately. Another is the transformation of some mechanical looseness. For example, if the iron core bracket is loose, the diagonal keys and pins become loose due to failure, and the rotor is not tightly tied, it will form a transformation and some imbalance. 2. Some mechanical problems mainly include the following points: (1) Some shafts in the linkage are misaligned, the centerline does not coincide, and the centering is incorrect. The primary reason for this type of problem is due to poor alignment an...

Volvo Engine Starting Make it a habit of giving the engine and engine room a visual check before starting. This will help you to discover quickly if anything abnormal has happened, or is about to happen. Also check that instruments and warning displays show normal values after you have started the engine. WARNING! Never use start spray or similar agents to start an engine. This may cause an explosion in the inlet manifold. Danger of personal injury. Before Starting • Check that the oil level is between the MIN and MAX marks. Refer to the “Maintenance, lubrication system” chapter. • Open the fuel taps. • Check that no oil, fuel or coolant leaks are present. • Check the air filter pressure drop indicator. Refer to the “Maintenance, Engine, general” chapter: • Check the coolant level and that the radiator is not clogged externally. Refer to the “Maintenance, cooling system” chapter: WARNING! Do not open the expansion tank cap when the engine is hot. Ste...

Volvo Engine Electronic Diesel Control? EDC 4 (Electronic Diesel Control) is an electronic system with CAN (Controller Area Network) or potentiometer communications for diesel engine control. The system includes fuel management and diagnostic functions. Overview The system includes sensors, control unit and an engine speed regulator. The sensors send input signals to the control unit, which in turn governs the injection pump control rack by means of an actuator in the engine speed regulator. Input signals The control unit receives input signals about engine operating conditions from the following components: 1. rpm sensor, camshaft 2. coolant temperature sensor 3. charge pressure sensor 4. oil pressure sensor 5. fuel temperature sensor 6. coolant level sensor (the function is implemented in the control unit as standard, but no sensor is supplied with the engine as a standard feature.) Output signals The control module uses the input signals t...
