The Influence of New Diesel Generator not Running-in After Overhaul

What should we do if the new diesel generator is overhauled without running-in? After the new diesel generator has been overhauled, the cylinder liner, piston, piston ring, and bearing bushes have been replaced. It has not been fully run-in and loaded with load, causing early wear and tear of the parts. And some also show the phenomenon of cylinder pulling and tile burning. After the diesel generator is cold-started, the oil viscosity is high and the flow resistance is also large, which makes the time lag for the oil to enter the friction pair, and all parts of the diesel engine are not fully lubricated, causing the gears and bearings of the diesel analyzer to be damaged due to poor lubrication , but also aggravated the wear of the cylinder and the bearing bush.

Especially supercharged diesel generators will cause ablation of the turbocharger's shaft. For this reason, the supercharged diesel generators should be idling for a while after starting, the standby oil temperature will rise, the fluidity will improve, and the turbocharger will be fully lubricated. Speed, which is more important in cold winters. This bulldozer was unloaded from the carrier vehicle during the cold winter season. The driver started the engine and drove towards the construction site at high speed. The next day, it was discovered that the diesel generator could run idling, but it could not turn under load. It turned out that the turbocharger ablated the shaft due to poor lubrication, and the air intake in the cylinder was reduced accordingly, and the power of the diesel generator was greatly reduced.

When the turbocharged diesel generator suddenly turns off when it is running at high speed, the oil pump immediately stops rotating, and the oil in the turbocharger also stops flowing. If the temperature of the exhaust manifold is very high at this time, its heat will be absorbed into the turbocharger housing, and the oil that stays there will be roasted into carbon deposits, blocking the oil inlet, causing the bushing to run out of oil, and speeding up the shaft and the shaft. The wear and tear of the shaft sleeve may even cause serious consequences of "seizure". Therefore, the supercharged diesel engine must be unloaded before stopping, let it idle for a few minutes, and then turn off the diesel generator after the temperature drops.

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.
