A water plant purchased a hydraulic generator. During use, the turbine volute cracked and leaked in many places, causing serious losses. The court entrusted our company to conduct quality appraisal of the "engine" involved in the case.

Identification situation: The wall thickness of the generator volute is seriously uneven. In addition, there are irregularities in the processing and installation of the generator, resulting in excessive vibration during operation.

Identification conclusion: The generator’s material and workmanship were unqualified and its installation was not standardized, which was the main cause of the accident.
