Implication

This analysis demonstrates the effects of various startup strategies on flow characteristics in parallel axial-flow pumps, suggesting optimal conditions for operation.

Key Points

Simultaneous startup results in internal pressure exceeding the rated head by 23.43%, indicating potential risk.
Sequential startup with 5 s intervals lowers pressure to 11.41% above rated head, while reverse flow increases to 13.87%.
A 15 s startup interval shows minimal improvements, with pressure and reverse flow decreasing by only 0.97% and 0.05%, respectively.
Implementing valve coordination with a 60% pre-opening during startup enhances stability, reducing pressure impacts effectively.
