  • In this paper, Firstly, it is shown that the high vibration and noise source of piping and pump system is the acoustic resonance. Secondly, in order to decrease the high vibration and noise of piping and pump system, the acoustic mode of piping have been changed and its effectiveness is investigated as applied it at piping system practically.

  • This paper suggests a non-contact sensor for measuring bending vibration of a non-metallic cylinder in two orthogonal directions simultaneously. Recent research shows that a solenoid can pick up bending vibrations of a nonmetallic cylinder based on the reversed Lorentz force mechanism if an electrical conductive patch is attached to the cylinder. In this work, pairs of specially designed patches are used to make two independent paths for the current induced by bending vibrations, which enables the measurement of bending vibrations along two orthogonal directions simultaneously. The working performance of the developed sensor was verified by using two accelerometers.
