Reasons for The damage Fuel Pump of Volvo Diesel Generator Set

Do you know the reasons for the damage of the fuel pump of Volvo diesel generator set? The external manifestation of the failure of the fuel pump of Volvo diesel generator set is insufficient fuel supply or no fuel supply. Work under load, or only work under no-load conditions. If the fuel pump does not supply fuel, it will cause the Volvo diesel generator set to fail to start. So what are the reasons for these problems in the oil pump? Let's look at the following.

There is a problem with the inlet and outlet valves of the oil transfer pump. The inlet and outlet valves are not closed tightly. The poor sealing of the inlet and outlet valves of the oil transfer pump will make it difficult to exhaust. The inspection method is to blow air at the oil outlet of the oil transfer pump. Normally, it should be blocked. If it can be blown through, it means that the oil outlet valve is not sealed; inhale at the oil inlet, it should be blocked under normal conditions, otherwise it means that the oil inlet valve is not sealed. It is also possible that the springs of the inlet and outlet valves are insufficiently elastic or broken. When the inlet and outlet valves are insufficiently elastic or broken, they will also cause the same consequences as the improper closing, which means that the exhaust of the Volvo diesel generator set will become difficult.

The problems of the oil transfer pump piston mainly include excessive wear of the oil transfer pump piston, piston stuck, piston spring broken, piston rod stuck, etc. The piston of the oil transfer pump is a very important focus in the principle of the oil transfer pump, when the piston-related parts or pistons When there is a problem, the force in the oil transfer pump will not be able to function correctly, then the operation of the oil transfer pump will have a problem. If the filter screen of the oil inlet pipe joint of the fuel delivery pump of Volvo diesel generator set is blocked, there will not be enough fuel to be delivered to the fuel injection pump, and the cylinder will cut off the fuel and cannot start. The fuel inlet filter of the fuel transfer pump is a component that filters the diesel of Volvo diesel generator sets. Generally, it filters out impurities in the diesel, so as to provide the generator with high-clean diesel. It will be filtered for a long time without cleaning. It will cause the filter to become clogged.

When the hand oil pump of Volvo diesel generator set is not closed tightly, some air will enter the oil pump, so that the internal pressure of the oil pump will become very large due to the air entering, so that there will be problems in oil suction, which is directly caused by the difficulty of oil suction. It will be a problem with the startup of the Volvo diesel generator set, or a failure in normal operation. The reasons that affect the fuel supply problem are loose fuel inlet pipe joints and insufficient fuel in the fuel tank. These two reasons will lead to insufficient fuel supply. Insufficient fuel supply will directly cause Volvo diesel generator sets to fail to start, even Volvo diesel The generator set suddenly stopped when it was running.

Starlight Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
