Incorrect Operation of Volvo Generators

Today we will give you a brief introduction about the incorrect operation of Volvo generators. If what else do you need to know about this, welcome to consult our Dingbo website, and then we will introduce the relevant content for you. .

Diesel engine runs when the oil is insufficient: At this time, insufficient oil supply will cause insufficient oil supply on the surface of each friction pair, resulting in abnormal wear or burns. For this reason, the Volvo generator must ensure sufficient oil before the start of the generator and during the operation of the diesel engine to prevent cylinder pulling and tile burning failures caused by lack of oil.

Sudden shutdown with load or immediately after the load is suddenly removed: the circulation of the cooling water stops after the Volvo generator is turned off, the heat dissipation capacity is drastically reduced, the heated parts lose cooling, and it is easy to cause the cylinder head, cylinder liner, cylinder block and other mechanical parts to overheat. Cracks occur, or the piston is over-expanded and stuck in the cylinder liner. On the other hand, if the Volvo generator is shut down without cooling at idle speed, the friction surface will not contain enough oil. When the diesel engine starts again, it will aggravate wear due to poor lubrication. Therefore, before the Volvo generator stalls, the load should be removed, and the speed should be gradually reduced, and the no-load operation for a few minutes (required no-load operation for 3 minutes).

After a cold start, the engine is operated under load without warming up: When the Volvo generator starts in a cold engine, due to the high oil viscosity and poor fluidity, the oil pump is insufficiently supplied, and the friction surface of the machine is poorly lubricated due to lack of oil, causing rapid wear and even tension. Failure of cylinder, burning tile, etc. Therefore, after the diesel engine is started, the engine should be idling to increase its temperature, and the standby oil temperature should reach 40°C or higher (when the cooling water reaches 60°C in winter use), then run with load; Drive for a certain mileage in the first gear until the oil temperature is normal and the fuel supply is sufficient, then it can be converted to normal driving.

The diesel engine blasts the throttle after a cold start: If the throttle is blasted, the Volvo generator speed will rise sharply, which will cause some friction surfaces on the engine to be severely worn due to dry friction. In addition, the piston, connecting rod, and crankshaft receive large changes when the throttle is hit, causing severe impacts and easily damaging parts.

Running under the condition of insufficient cooling water or too high temperature of cooling water or oil: Insufficient cooling water of Volvo generator will reduce its cooling effect, diesel engine will overheat because of ineffective cooling; oil temperature of cooling water and engine oil is too high, It can also cause the diesel engine to overheat. At this time, the main heat load of Volvo generator cylinder head, cylinder liner, piston assembly and valve, etc., its mechanical properties such as strength and toughness drop sharply, which increases the deformation of the parts, reduces the matching gap between the parts, and accelerates the wear of the parts. , In severe cases, cracks and malfunctions of mechanical parts jamming may occur. Overheating of Volvo generators can also worsen the combustion process of diesel engines, causing injectors to malfunction, poor atomization, and increased carbon deposits.
