Six Basic principles of dredge pump impeller design
The impeller of dredge pump is the core, fragile, heavy-weight dredge pump accessory that is the core in the design, production, and use process, so what are the basic principles of dredge pump impeller design?
The basic principles of centrifugal dredge pump impeller design are as follows:
1. In the design of the dredge pump impeller, it is necessary to fully consider its anti-wear property and the feasibility of its manufacturing process. At the same time, it is convenient for the operator to operate on site.
2. Ensure that the designed impeller can meet the requirements of the actual working conditions.
3. Over-current capability: When designing the pump, it must also consider its over-current capability. If the particle size of the solid particles in the slurry is large, the passability of these coarse particles should also be considered in the design. The theory and practice show that the reasonable selection of the number of blades and the inlet angle of the impeller can ensure the smooth passage of the coarse particles by appropriately reducing the number of blades of the impeller or increasing the inlet angle.
4. The designed dredge pump must have practicality but at the same time take into account its efficiency and convenience.
5. Apply numerical methods in the cavitation process, including the background of NPSH and cavitation, to optimize the blade size, structure and shape related parameters of the pump body;
6. Theoretical analysis, establish the gas flow model of each stage of the impeller operation process; secondly, summarize the analysis results of the existing pump and the detailed information of the traditional design (work).
Finally, it is verified with an optimized design and the performance of its numerical predictions.
