Abstract According to the problem existing in the traditional technological water-supply, principle of applying variable frequency timing technology to adjust water pressure and selection of water-supply equipment with variable frequency are introduced. Problem existing in water-supply with variable frequency in Xinmu river Dapu pumping station and resolution are put forward. Results show that it is very important to adopt variable frequency and constant pressure to ensure steady water pressure and to realize auto-control in pumping station.
