Witryna14 kwi 2024 · The initial model impeller with the balance hole circumferential position angle θ = 30° is selected as the test object to carry out the external characteristic test of the centrifugal pump. The test system is a visual test bench for centrifugal pumps, as shown in Figure 5. Witryna15 sty 2024 · Schäfer et al. (2015, 2024) found that the gas-phase accumulation in the impeller flow channel with balance holes is weaker than the flow channel without balance holes. The gas volume changes in the flow channel with a balance hole are more gradual than those without holes at increasing IGVF.
