Single-stage centrifugal pump how to choose
Single-stage centrifugal pump selection Single-stage centrifugal pump vertical centrifugal pump, horizontal centrifugal pump two categories. First, the single-stage centrifugal pump seal the product selection of carbide mechanical seal, with high efficiency and energy saving, reliable performance, easy installation and use. 1, vertical centrifugal pump for the vertical structure, import and export of the same caliber, and located in the same center line, the same as the valve can be installed in the pipeline, the shape compact and beautiful, small footprint, low investment, such as adding Protective cover can be placed outdoors. Vertical centrifugal pump main purposes (1) ISG centrifugal pump for the delivery of water and physical and chemical properties similar to other liquids used for water, suitable for industrial and urban water supply and drainage, high-rise building pressurized water, garden irrigation, fire pressurization, Long-distance transmission, HVAC refrigeration cycle, bathroom and other heating and cooling water circulation and equipment support, temperature T <80 ℃. (2) The vertical type hot water pump is widely used in circulating pump of high-temperature hot-water boilers and urban circulating pump for urban heating system in energy, metallurgy, chemical industry, textile, papermaking, hotels and restaurants, IRG type temperature T <120 ℃, GRG type temperature T <240 ℃. (3) Vertical Chemical Centrifugal Pump For the transportation of liquids containing no solid particles, corrosive and viscosity similar to water, it is suitable for petroleum, chemical, metallurgy, electric power, papermaking, foodstuff, pharmaceutical and synthetic fiber, 20 ° C to 120 ° C. (4) vertical centrifugal pump for the delivery of petrol, kerosene, diesel and other petroleum products, the medium temperature is transported -20 ℃ ~ +120 ℃. 2, horizontal centrifugal pump occupies more province: the export can be left, right, up three directions, the pipeline layout and installation, saving space. Horizontal centrifugal pump main purposes (1) horizontal centrifugal pump for conveying water and physical and chemical properties similar to other liquids used for water, suitable for industrial and urban water supply and drainage, high-rise building pressurized water, irrigation garden, fire booster, Long-distance transmission, HVAC refrigeration cycle, bathroom and other heating and cooling water circulation booster and equipment supporting the use of temperature t ≤ 80 ℃. (2) horizontal hot water centrifugal pump is widely used in: metallurgy, chemicals, textiles, paper and hotels boilers and other hot water pressurized circulating transport and urban heating system, iswr-type use temperature t ≤ 120 ℃. (3) horizontal chemical pump for the delivery of non-solid particles, corrosive, viscosity similar to water, suitable for petroleum, chemical, metallurgical, power, paper, food and pharmaceutical and synthetic fiber and other departments, the use of temperature - 20 ° C to + 120 ° C. (4) horizontal centrifugal pump for the transportation of gasoline, kerosene, diesel and other oil products or flammable and explosive liquids, medium temperature is -20 ~ +120 ℃.
