A water supply project, how to choose electrodes and frequency converters, such as giving a 7-storey water supply
4. Set by pressure (0.3-0.4Mpa). Control the inverter can be.
3. Take a doorway as an example: choose DN50, N = 7.5Kw enough. About 50 cubic meters / H.
2 pump power: If there is a tank, optional small pump, or should see how many households, fixed flow.
1. Select the pressure pump head: 7 * 2.5 (3) = 17.5 (21) meters; this is the number of theory, in fact, should be selected 40 meters, (0.4Mpa).
