Maintenance tips for diesel generator sets in winter:
After the diesel generator set is put into operation in winter, if it is parked in an open-air place, one should always pay attention to the changes in the weather. When the local temperature drops below 4 degrees, the cooling water in the diesel engine’s cooling water tank should be drained. This is because at 4 degrees, the volume of water changes significantly. When water changes from liquid to solid, the volume increases and expands, which will damage the radiator of the cooling water tank.
Second, in winter, due to the poor working environment of diesel engines, it is necessary to frequently replace the air filter element. As the requirements for air filter elements and diesel filter elements are particularly high in cold weather, if they are not replaced in time, it will increase the wear of the engine and affect the service life of the diesel engine.
When choosing engine oil for diesel generator sets in winter, it is advisable to select oil with a lower viscosity as much as possible.
When starting a diesel engine in winter, the temperature of the air drawn into the cylinder is relatively low, and it is difficult for the piston to compress the gas to reach the natural temperature of the diesel. Therefore, before starting a Cummins diesel engine, corresponding auxiliary methods should be adopted to increase the temperature of the Cummins diesel engine block.
V. After starting the diesel engine, it should run at low speed for 3 to 5 minutes first to increase the overall temperature of the Cummins diesel engine. Check the working condition of the lubricating oil. Only after confirming that everything is normal can it be put into normal operation. During the operation of a diesel engine, it is advisable to minimize sudden acceleration of the engine speed or pressing the throttle to the rated level. Otherwise, over time, this will affect the service life of the valve assembly.
Maintenance tips for diesel generator sets in summer
In summer, it is rather muggy and humid. It is important to ensure that the normal ventilation and cooling of the generator are not affected. Dust and dirt in the ventilation ducts should be cleaned frequently to keep them unobstructed.
Second, summer is a season with frequent thunderstorms. On-site lightning protection work must be done well at the location of diesel generator sets. All kinds of mechanical equipment and ongoing construction projects must be properly grounded for lightning protection as required, and the generator set devices must be properly connected to zero for protection.
Iii. For generator sets installed, they should be interlocked with the external power line power supply. Switching devices or dual power main distribution boxes can be set up. Parallel operation is strictly prohibited. After work, the power supply of all kinds of mechanical equipment should be cut off to prevent all kinds of electric shock accidents.
The disassembly and assembly methods of the generator are roughly the same as those of the asynchronous motor. However, due to the heavy weight of the generator, care should be taken not to damage it during disassembly and assembly. When removing the end cover, be careful not to damage the stator coil protruding from the surface of the frame. When removing the rotor, place cardboard between the stator and rotor of the motor to prevent damage to the core and windings. When binding the rotor with steel cables, the cables must not touch the rotor journal, fan, collector slip or rotor lead wire.
In order to maximize the utilization rate of diesel generator sets, it is necessary to carry out maintenance and upkeep on them. The focus of maintenance and upkeep varies in different seasons. Therefore, for enterprises using diesel generator sets, it is essential to treat the maintenance and upkeep of generator sets differently according to the seasons.
