Bionics technology on resistance and noise reduction of centrifugal pump

During the actual operation the centrifugal pump will suffer a great energy loss due to the friction resistance between the fluid and the over current components and create great noise due to the hydraulic pulsation caused by the complex distribution of flow field In order to reduce resistance and noise it is significant to apply the bionics technology Through the observation and study of the natural biological characteristics some available bionic structure has been designed to improve the properties of centrifugal pumps Combined with the traditional resistance and noise reduction technology the bionics technology such as super hydrophobic pump non smooth impeller ladder tongue and bionic volute show efficient and simple functions of resistance and noise reduction In current studies bionics technology had abilities of reducing the friction resistance between the fluid and over current components improving distribution of pressure and reducing radial force It can be seen that bionics technology will be widely used in resistance and noise reduction of fluid machinery
