JianCeFa voice: (1) small based environment using tons of 20 db sound out mike high quality SKF Bearings the crisis signal extraction of distance and direction some economic analysis method more perfect more direct measurement of sound.
(2) : you JianCeFa vibration sound more indirect detection method, can be found and Shared JianCeFa quantitative JianCeFa media. Required more sound vibration waveform inspection and supervision and inspection method. Quantitative inspection "refers to the medium bearing is defined as a concussion and audio signal, the media and in-kind is worth more than shock wave peak bearing the culmination of the number of abnormal flow design.
(3 months), measure the bearing bearing sound meter measuring instrument to measure many sound more = = hangzhou bearing test center bant - 1 type bearing voice tools; More s092 bearing institute of Shanghai bearing (more than) tools; Luoyang bearing research institute and the dalian bearing instrument factory Ⅲ - s0910 common development. This bearing tester measuring values, bearing, bearing can measure impact reflect more the culmination of quantitative factors and sound media such as electromagnetic wave.
