Principle Analysis of Low Oil Pressure of Volvo Diesel Generator

There are many reasons for low oil pressure of Volvo diesel generator. Here we will analyze the most common reasons. If the temperature of the coolant of Volvo diesel generator is maintained at a high temperature for a long time during operation, it will lead to low oil viscosity, which will lead to low oil pressure. Failure of the oil pressure sensor or short circuit of the sensor signal to the ground may also lead to low oil pressure, Other factors that lead to the low oil pressure of Volvo diesel generator, such as the failure to change the oil filter at the same time as required when changing the oil, resulting in the blockage of the oil filter in the later use, resulting in the insufficient oil supply of the oil pipeline, and also the low oil level, and the viscosity level of the lubricating oil used does not meet the requirements of Volvo diesel generator operating environment. The above factors are the main factors that lead to the low oil pressure warning and fault of Volvo diesel generator. If the cause is not found, you can ask a professional repairman to find and remove the fault. Here are some methods to deal with the low oil pressure fault of Volvo diesel generator.

If the alarm caused by low oil pressure occurs during the operation of Volvo diesel generator, the operation shall be stopped immediately for treatment. After the shutdown, first check the scale of the oil scale to ensure that the oil level is close to the H position between the L and H positions of the scale after the shutdown for five minutes. If it is insufficient, the same type of oil shall be replenished in time to the specified full oil scale. If the coolant temperature of Volvo diesel generator is found to be too high during inspection, it shall be stopped immediately and treated with corresponding methods to ensure that the coolant temperature is kept within the specified temperature value.

Check the oil filter of Volvo diesel generating set. If it is found that the oil filter is blocked, it should be replaced in time. In addition, it is necessary to replace the oil filter at the same time when changing the oil to prevent its blocking and causing machine failure. Before starting and running Volvo diesel generator every time, check whether the oil filter is blocked, and replace it immediately if any.

Check the wiring on the oil pressure sensor to ensure its connection is firm and reliable. Record the resistance pressure of the oil pressure sensor when the Volvo diesel generator is turned on, and then compare it with the following table. If the difference is large, replace the oil pressure sensor immediately. Check whether the viscosity of Volvo diesel genset oil meets the standard. If the viscosity is too low, replace the qualified oil in time.
