- •
Operation characteristics model of parallel pump set is built based on bypass loop.
- •
Operation characteristics are analyzed in multiple differential pressure conditions.
- •
Control strategy has remarkable selectivity to flow and differential pressure.
- •
Single pump frequency is a more suitable in high differential pressure condition.
