【Abstract】 A set of hydrodynamic noise measurement and control system was designed for new designed centrifugal pumps, the measurement principle of two transfer function method was briefly introduced in this paper, by using this system, a series of measurement and analyses can be received for measuring the hydrodynamic noise. The results showed that it is a good measurement system for measuring low noise centrifugal punps.更多还原
