1. Appearance inspection: mainly to check whether the appearance of the generator is intact and undamaged, and whether there are obvious deformations, cracks, or scratches. At the same time, it is necessary to check the fastening of each component to ensure that there is no looseness or detachment.

2. Electrical performance testing: including the detection of output voltage, current, frequency and other parameters of the generator. It is necessary to use professional testing instruments for testing and strictly follow the prescribed standards to ensure that the electrical performance meets the requirements.

3. Mechanical performance testing: including the detection of parameters such as the speed, steering, and torque of the unit. It is necessary to use professional testing instruments for testing and strictly follow the prescribed standards to ensure that the mechanical performance meets the requirements.

4. Quality inspection: It is necessary to check whether the materials and components used meet the requirements, as well as whether the processing and manufacturing processes are standardized, to ensure that the quality of the generator meets the standards.

5. Environmental adaptability check: It is necessary to check whether the generator can adapt to different environmental conditions, such as temperature, humidity, altitude, etc.

6. Safety inspection: It is necessary to check whether the safety performance of the generator meets the requirements, such as whether there is leakage, overload protection, etc. At the same time, it is necessary to check whether the protective measures of the unit are complete to ensure the safety of the operators.

Through the above inspection, it can be ensured that the quality and performance of the diesel generator meet the requirements and can be safely and stably used for power supply in various occasions.
