How The Diesel Generator Manufacturers Test Generator Sets?

May. 10, 2022

Before the diesel generator leaving the factory, it must be strictly tested and approved before leaving the factory. Today, our diesel generator manufacturers talk about how to test diesel generators? First of all, the starlight power generation equipment is completed in a complete set according to the specific production requirements of diesel generators, and placed on the test bench to prepare for the test work.

1. Fill the tested diesel generator with coolant and enough lubricating oil, connect the load line cable, install the smoke exhaust pipe, and connect the starting battery;


2. Preliminarily observe whether the diesel generator has improper installation or wrong installation, whether there is oil leakage or water leakage, and test various indicators of the diesel generator, such as withstand voltage test, inter-turn test, etc. If there are unqualified items, modify and deal with them in time;


3. After the unit is successfully started, idling for 2-3 minutes to observe whether there is any abnormal situation, confirm that there is no abnormal situation, and increase the high speed to 1500 rpm, observe various test data, the voltage is 400V when the frequency is 50HZ, the oil pressure is not less than 0.2MP, the silicon generator Whether the charging is normal, check the engine for oil leakage, water leakage and air leakage. The unit is in normal condition, and the water temperature rises to 60°C, and the switch is ready to run the load test;


4. According to the rated power of the diesel generator, the load test is carried out in different stages, and the test is carried out in several load stages of 25%, 50% and 100%. If each load stage is maintained at a frequency of 50HZ and a voltage of 380V- Between 420V, when the power factor is 0.8, the power is multiplied by the 1.8 coefficient. When the theoretical data of the current is consistent with the load current reading, the unit power is considered to be qualified; observe the vibration of the engine and the change of the smoke color during operation; refer to the engine's Standard to judge whether there is a fault;


5. After the unit test is completed, make a record of the test load, note the test time and the employee number of the tester, do a good job in the recordation of the unit, and stamp the qualified seal. The unit is allowed to leave the factory.
