Do a Good Job in Monitoring Cummins Diesel Generator Sets

Cummins, as a well-known imported brand of diesel generator sets, has always been favored by users for its stable working performance and advanced technological level. In order to ensure the stable operation of Cummins diesel generator sets, Dingbo Power recommends that all users implement experience monitoring and subsystem monitoring during the operation of the units.

In the operation process of Cummins diesel generator sets, experience monitoring and subsystem monitoring are equally important. Experience monitoring mainly relies on the experience of diesel generator set operators to monitor their operating conditions. The main monitoring methods are to judge the operation and power supply of the unit through "listening, touching, seeing, smelling" and other methods; And subsystem monitoring is the operator's monitoring of each subsystem, which will directly affect the power supply quality of Cummins diesel generator sets. Therefore, it is necessary to conscientiously implement the management regulations of diesel generator sets. Below, Dingbo Power will focus on explaining the monitoring measures for each subsystem of Cummins diesel generator sets.

1. Operating system monitoring

The floating value of the output current frequency of the diesel generator set must be within the specified range. If the fuel supply handle jumps or slides due to long-term power supply, it will cause unstable speed of the Cummins diesel generator set and affect the frequency of the output current. Therefore, the operator must lock the fuel supply handle at the rated speed position after adding load to the generator set.

2. Fuel system management

During the operation of Cummins diesel generator sets, it should be ensured that the diesel is clean, free of impurities, leaks, and there is no air allowed in the system. If impurities in diesel clog various filters, it will cause interruption or insufficient fuel supply to the Cummins diesel generator set. Therefore, this situation is absolutely not allowed to occur during operation. When the diesel generator set is running at rated speed, if there is oil leakage at various interfaces, fuel injection pumps or fuel transfer pumps, or air mixed in the fuel supply mechanism, it will cause poor power and unstable frequency of the entire Cummins generator set.

3. Lubricating oil system

The management of various systems of lubricating oil is generally judged from three aspects: oil pressure, oil temperature, and oil quality. During the operation of Cummins diesel generator sets, it is necessary to regularly observe the oil pressure and the oil level gauge on the oil pan. If the parts of the diesel engine that need lubrication are not sufficiently lubricated, it will cause damage to the Cummins diesel generator set. Therefore, Cummins diesel generator sets not only need to ensure the oil quality and quantity of the oil during operation, but also need to regularly check the oil quality and quantity in daily life.

4. Cooling system management

In the entire cooling system of Cummins diesel generator sets, the first step is to ensure normal water temperature. If the water temperature is too high or too low, it will affect the power generation quality of the diesel generator set. When the load power of the diesel generator set reaches 80% of the power of the diesel generator set, it is necessary to heat the diesel generator set in advance to maintain the water temperature within the range of 70 ° C~85 ° C, otherwise it will cause damage to various components of the diesel generator set.

During the operation of Cummins diesel generator sets, in order to ensure normal operation and avoid safety accidents, users must implement the above monitoring measures.
