Diesel generator sets need to be run-in, no matter what equipment needs to run-in period, the purchase of a new car also needs to run-in.
However, diesel generator sets are also run-in after overhaul because the engine parts have been completely replaced or have been updated after maintenance. The surface of the part is not smooth and is immediately used under high temperature, high pressure, high speed and full load conditions, which will cause wear of the parts and shorten the service life of the generator set. Therefore, the running-in use of diesel generator sets is very important.
Shandong Commler generator reminds you that there are two kinds of running-in of diesel generator sets, namely cold running and hot running. The cold running-in of a diesel generator set means that the diesel engine is driven by a motor or other power on the test bench.
The shaft is operated to achieve the purpose of running the crankshaft linkage, the valve train and other moving parts. In this process, it is necessary to use oil with low viscosity, and it is also possible to perform a fault check on the diesel generator set to see if there are abnormal sounds, pull cylinders and air leaks.
The heat-running of the diesel generator set refers to the completion of the installation of the diesel engine, and after detailed inspection, the machine is started up, and the engine is further inspected and adjusted through the no-load and load test, so that it has good power and economy. In this process, we should pay attention to check the assembly condition of the machine parts and the proper clearance between the fittings, whether the engine is running evenly, whether the piston, piston pin, crankshaft main bearing and connecting rod bearing have special sound.
According to the standards for the use of diesel generator sets, diesel generator sets have different requirements in terms of altitude, ambient temperature, relative humidity, presence or absence of mold, and inclination. Its power is for a specific environmental situation. Environmental conditions refer to the ambient atmospheric pressure, temperature and relative humidity of the diesel engine operating location, which have a significant impact on the performance and operating efficiency of the diesel engine. Therefore, we are not only concerned about whether the diesel generator set needs to be run-in, but also pay attention to its use environment. When the ambient atmospheric pressure is lowered, the temperature rises and the relative humidity increases, the dry air sucked into the cylinder of the diesel engine will be reduced, and the power of the diesel engine will be reduced. Will lower. On the contrary, the power of the diesel engine will increase. Shandong Commler will provide more diesel generators using skills. After all, with many years of experience in generator set production, the generator sets produced have received satisfactory feedback from users, and a lot of relevant diesel generator sets have been summarized through practice. skill.
