Hydraulic pump installation matters needing attention
The position of the pump shall be consistent with the sound source position and the measurement surface (or the route of the microphone) specified in the international standard corresponding to the experimental environment adopted.
1.The design of pump seat should minimize the noise caused by pump vibration.
2.The fixed support plate of oil pump shall be made of high damping material or sound damping and sound absorbing material.
3.Even if the pump is installed reliably, isolation technology should be used if necessary.
4.Use small flange mounting as far as possible to limit interference from noise radiation toward the pump shaft end.
