Pump (pump) model representative of the meaning

Pump model on behalf of the structural characteristics of the pump performance and the nature of the medium being transported. Due to the wide variety of pumps, different specifications, so the model is also more turmoil, only a few common pump models are listed here. BA pump single-stage single-suction cantilever centrifugal pump, flow rate of 4.5 ~ 360 m ³ / hour, head to 8 to 98 meters, the media temperature below 80 ℃. 8BA - 18A as an example: 8 - on behalf of the suction pipe joint for the 8-inch; BA - on behalf of single-stage single-suction cantilever centrifugal pump; 18 - represents the reduction of 1/10 into an integer than the number of revolutions; A - Represents an impeller with reduced outer diameter. SH type pump single-stage double-suction horizontal horizontal centrifugal pump shell open, the flow of 102 ~ 12500 m ³ / hour, the head is 9 ~ 140 meters, medium temperature is less than 80 ℃. Such as 48SH-22: 48 - on behalf of the suction pipe connector is 48 inches, that is, the inlet diameter of 1.2 meters; SH - on behalf of single-stage double suction pump horizontal shell horizontal centrifugal pump; 22 - represents a 1 / 10 into the integer than the number of revolutions, that is, ns ≈ 220. DA type pump single-suction multi-stage segmented centrifugal pump, the flow of 25 ~ 350 m ³ / hour, head to 25 to 550 meters. Such as 3DA8 × 9: 3 - suction pipe diameter of 3 inches; DA - This type multistage segmented centrifugal pump, and the old model SSM similar, suitable for cold water ≤ 40 ℃; 8 - After into the integer business; 9 - impeller series, 9. DG-type single-suction pump multi-stage boiler feed pump. Such as DG270-150: DG - boiler feed pump; 270 - flow, m³ / hour; 150 - outlet pressure, 150 kg / cm ². N, NL type pump condensate pump N, NL type, used to transport the temperature below 80 ℃ condensate. Such as 8NL-12: 8 - suction nozzle diameter in inches, 8 inches; N - condensate pump; L - vertical structure; 12 - single-stage head was divided by 10 integer values. NB, NBA, GN, GNL-type pumps for thermal power plant delivery temperature does not exceed 80 ℃ condensate. N - Condensate pump; B - Suspension; BA - Bracket; G - higher suction; L - vertical. Xiangjiang brand single-stage double-suction horizontal open horizontal centrifugal pump, can be used as a circulating pump. Such as the Xiangjiang River 56-28: Xiangjiang - large single-stage double-suction in the open horizontal centrifugal pump; 56 - suction pipe diameter 56 inches; 28 - reduced by 1/10 than the number of revolutions. PW-type pump for the sewage cantilever single-stage pump. Such as 6PWL 6 - discharge pipe diameter inches; P - impurity pump; W - sewage; L - vertical. Source: Yangtze River Pumping Network
