Description

Turbine generators must be subjected to stringent reliability tests prior to application to downhole tools.

However, in the actual testing process, due to the problem of the fixation of the generator test bin, the high-speed rotation of the generator can lead to the integral vibration of the generator test stand, so that the efficiency of the generator in the high-speed rotation process is affected.
