Treatment Method After Volvo Diesel Generator Set Failure

When the starting speed of Volvo diesel generator set is normal, the cylinder compression is good, but there is no ignition and no smoke, it mainly caused by insufficient fuel supply in the low-pressure oil circuit. At this time, inspections are mainly carried out along the fuel tank, fuel pipeline, diesel filter, fuel pump and fuel injection pump, and the faulty parts can generally be found. The main reason for the clogging of low-pressure oil pipes and filters is poor diesel filtration of Volvo diesel generator sets or unplanned cleaning of filters. To determine whether the oil circuit or filter is blocked, the filter of the Volvo diesel generator set can be removed through the fuel pipe of the fuel injection pump.

If there is a lot of oil in the fuel tank of the Volvo diesel generator set, and there is little or no oil in the filter, it means that the filter is clogged. If the low-pressure fuel supply is good, the main cause of the high-pressure oil-free diesel engine of the Volvo diesel generator set is the wear of the plunger of the fuel injection pump or improper assembly. The vehicle speed is normal, and the sound of fuel injection can be heard, but it cannot be started, mainly due to poor compression of the cylinder.

If the decompression mechanism is in the non-decompression position, the Volvo diesel generator set can still be rotated by hand, and the resistance is not very large, the cylinder leakage can be determined. After the intake valve or exhaust valve of the Volvo diesel generator set leaks, Volvo diesel The compression temperature and pressure in the cylinder of the generator set are not high, and diesel is not easy to ignite. The valve clearance of Volvo diesel generator sets is too small and not closed tightly. There are impurities such as carbon deposits on the valve sealing cone or valve seat, which also makes ignition difficult. The valve is not closed tightly. During the inspection, the crankshaft of the Volvo diesel generator set can be turned. If you hear a "squeak" sound in the air filter and exhaust pipe of the Volvo diesel generator set, it can explain the leakage of the intake and exhaust valves of the Volvo diesel generator set.

If a leak is found at the interface between the cylinder head and the cylinder block of the Volvo diesel generator set, it indicates that there is a leak at the cylinder head gasket of the Volvo diesel generator set. It may be that the cylinder head nut of the Volvo diesel generator set is not tightened or loosened, or the cylinder head gasket is damaged. When the crankshaft of the Volvo diesel generator set rotates, the sound of air leakage will be found inside the body of the Volvo diesel generator set or at the oil outlet of the engine, which is mainly caused by the piston ring.

In order to find out whether the insufficient compression force in the cylinder of the Volvo diesel generator set is caused by the damage of the piston ring, an appropriate amount of clean lubricating oil can be added to the cylinder of the Volvo diesel generator set. If the compression force in the cylinder increases significantly after refueling, it indicates that the piston ring of Volvo diesel generator set is worn too much, the clearance between the cylinder and the piston ring is too large, and the air is between the piston ring and the cylinder liner. Leak into the crankcase. If you add fuel, the compression force does not change much, indicating that the insufficiency of the compression force in the cylinder of the Volvo diesel generator set has nothing to do with the piston ring, and it may be the intake valve or exhaust valve of the diesel genset.
