Centrifugal pump hydraulic design

Centrifugal pump hydraulic design to solve three problems: 1) the main parameters of the flow components, as well as the best ratio of each part of the components. 2) flow design, selected in the hydraulic design process flow components selected flow rule. Such as the distribution of the circumferential velocity of the volute, the distribution of the impeller ring flow and the distribution of the axial velocity. These distributions are pre-design assumptions. 3) Impeller blade and runner profile design, to provide over-current parts of the processing wood map. Centrifugal pump in the hydraulic design process should be as far as possible to achieve: 1) to ensure that the design parameters to meet the requirements of flow and lift; 2) the centrifugal pump has good energy performance, that is, higher hydraulic efficiency, and high efficiency zone As wide as possible; 3) good cavitation and cavitation erosion, reduced efficiency due to cavitation reduction; 4) good stability with low pressure pulsations and noise values; and 5) as small dimensions as possible to reduce Cost; 6) to meet the requirements of some special operating conditions, such as deep wells, diving and high sediment flow and other special requirements; 7) to meet the manufacturing requirements of the installation process.
