Mechanical Vibration Test Bench

Scope of Application  

This standard applies to the shaft center height.630mmAbove, speed of150～3600r/minApologies, but there is no Chinese content provided for translation. Please provide the text you wish to translate. AC Motor, Industrial Electric Motor  

This standard does not apply to vertical hydraulic generators or steam turbines.  

Measurement Value  

RPM600r/minMotors above this specification utilize the large root mean square (RMS) value of vibration speed.(mm/s)Please provide the Chinese content to be translated into American English. 600r/minOur motor utilizes displacement amplitude.(mm,Dual-value)No Chinese content provided.  

Measurement Instruments  

 The vibration intensity measuring instruments used should be certified by the national metrological department, and the entire measurement system should be checked before use. Various units(Including sensors, vibration intensity meters, recording and display instruments, etc.)Perform calibration to ascertain itsPlease provide the Chinese content to be translated..

 Measurement of Revolution Speed600r/minAt the vibration intensity of the above motor, the frequency of its vibration intensity measuring instrument No Chinese content provided.10～1000HzOr above, the relative sensitivity within its frequency response range80HzThe translation is missing the actual Chinese content to translate. Please provide the Chinese text you would like translated. Based on the relative sensitivity, the relative sensitivity of other frequencies does not exceed+10%Or-20%。  

Measure RPM below600r/minWhen measuring the vibration intensity of an electric motor, a low-frequency sensor and low-frequency vibration intensity should be used. Diameter Measuring Instrument, ensuring measurement accuracy less than±10%The requirements.  

 The sensors must have a good contact with the points being measured, and ensure that the installation of the sensors does not affect the measured components. The vibration status.  

Vibration intensity measuring instruments and gauges should be periodically calibrated in accordance with national regulations.
