Measurement of Hydraulic-Turbine Vibration

Journal of Fluids Engineering, 1952
Abstract This paper describes a test program used to measure and eliminate the vibration which had produced extensive cracking in the blading of a slow-speed, 40,000-hp hydraulic turbine. Strains, accelerations, and pressures were measured at various locations on the turbine runner while the unit was in operation.

Cavitation in Hydraulic Turbines

1962
The most common and troublesome maintenance problem encountered with hydraulic turbines is the erosion caused by cavitation. A study of the cavitation phenomenon has demonstrated that the pressure produced by the collapse of cavitation bubbles is sufficient to cause mechanical erosion of all known materials. However, the resistance to cavitation damage

Index Testing of Hydraulic Turbines

Journal of Fluids Engineering, 1951
Abstract The object of this paper is (a) to bring to the attention of operating companies the benefits derived from index tests of hydraulic turbines, and especially those of the adjustable-blade propeller or Kaplan type; (b) to enumerate and discuss the presently known methods of determining relative discharge and hence relative ...

Hydraulic Turbine Setting Criteria

Journal of Engineering for Power, 1965
Higher settings of hydraulic turbines are proposed which will result in lower relative tailwater levels with associated operational improvements. Present selling criteria may lead to unsatisfactory operation at higher tailwater levels. Cavitation damage is not necessarily prevented by low settings, and draft-tube surges may occur under high tailwater ...
