- 适用范围
- 1.1.1 This guide applies to any type of reaction or impulse turbine. as well to any type of pump-turbine and storage pump, coupled to an electric generator or motor. 1.1.2 The guide covers the field ofvibration and pulsation tests referred to as standard tests. The objectives ofthe tests are as follows: Assessment of hydraulic machine design: manufacture and quality of erection from the viewpoint ofvibration**. Assessment ofthe changes of vibration behaviour during the machine life. Provision of recommendations applying to operation of unit (for instance, choice of the most appropriate transient sequences). Aid in analysing faults and break downs. 1.1.3 If it is not possible to apply the recommendations ofthe guide because ofthe construction of the hydraulic machine. or if it is not necessary to conduct some of the measurements, such items may be omitted on prior agreement between the manufacturer and the user.
