Impeller design. The required pressure rise and flow rate of the pump was defined from previous literature[9, 10]. Some design parameters are assumptions made by the designer based on experience and previously designed pumps. 62 axial pump impellers with varying outlet angle and number of blades are designed.

The total axial load has two components: (1) the shaft load due to the differential pressure acting on the shaft cross-sectional area and (2) the sum of the axial loads occurring in the pump stages. Clearly, thrust bearings of much greater capacity than that for floater pumps are required for proper operation.

An analytic method for designing blades of the impeller of an axial dredge pump is developed. The method al-lows a mathematical description of the skeleton line as a parabola, taking into account the entrance and exit angles of the blade. The method can be used in CAD software to design axial-flow pumps.

Posted in Pump. An axial pump, also known as an axial-flow pump, is a type of pump that moves fluid by means of an impeller with blades that generate an axial (parallel to the shaft) flow pattern. Unlike radial-flow pumps, where fluid moves outward from the pump's center, in axial pumps, the fluid flows in the same direction as the …
