WitrynaAs the passage approaches the periphery of the body section 27, it opens to the periphery While the circular. sectioned passage is presently preferred, it is to into and initially as indicated at 38 in Fig. 6, and thence continues along the periphery of the impeller until the bottom surface 39 of the passage merges into the impeller … Witryna17 gru 2011 · For a radial vane design, this flow will be directed out to the impeller periphery making this area the predetermined point of wear. For true heavy duty radial vane recessed impeller pumps, the casing will not suffer this wear as it is protected by an independent heavy duty peripheral wear plate assembly.

WitrynaThe effect of pump impeller modification by a new approach, pump impeller shroud trimming (PIST), on the flow field and pump performance is examined both … WitrynaThe single volute design imposes a radial force on the impeller due to variations of pressure around the impeller periphery above and below best efficiency point flow. In cases where this radial force results in excessive shaft deflection, a double volute design (Figure B) is used.
WitrynaRadial vortices caused by shear between the counter-rotating impellers provide coherent sink flow conduits for axial extraction of nitrogen ballast.
