Performance range D-type multi-stage centrifugal pump: flow rate Q: 6.3 ~ 600m3 / h Head H: 17 ~ 850m seven, D-type multi-stage centrifugal pump Model Description: 100 D 16 * 3100 is the pump inlet diameter 100mmD multistage 16 is a single-stage centrifugal pump designed head centrifugal pump selection 1, should choose high efficiency, low noise, energy-saving horizontal centrifugal pump, non-select out of product. 2, should be based on the design flow, the required pump head is selected, and consider the pump due to wear and tear and other causes pump output decline, resulting selected pump head H is multiplied by 1.05 to 1.10 coefficients can be calculated; characteristic curve should be selected with the flow rate increases It decreased its head pump, so the pump is stable, reliable work in parallel; and the operating point of the pump should be maintained in the high range of operation, such as energy and not easily damaged parts. 3, when the water supply network unregulated facilities, should adopt the rated speed governor pump or pump group running water. The maximum amount of water should not be less than residential water supply pump design flow, and should be checked with the fire conditions. 4. Select the tank, tower lift pump should minimize the number of units 100d-16 * 4 mine multistage pump, should one with a prepared; when the single pump to meet the requirements of mining multi-stage pump, you should not use more than one parallel ; if you must use more than one parallel operation or size of the pump with the way, the model, the number of units should not be too much, generally not more than two kinds of model 100d-16 * 5 mine multistage pumps, horizontal centrifugal lift range should be similar; parallel run efficiently area still within range of each pump should run. 5, life pressurized water system pump unit should be set up standby pump, spare pump water supply capacity should be greater than the maximum running pumps a water supply capacity 100d-16 * 6 mining multi-stage pump, the pump should automatically switch alternately run. 6, horizontal centrifugal pump with the motor voltage should be the same, and the power with the national power grid format the same standard.
