I. Overview ISG-type single-stage single-suction pipeline centrifugal pump, the United States is the scientific and technical personnel within the pump selection of domestic excellent hydraulic model, the use of IS-type centrifugal pump performance parameters, based on the general vertical pump design and clever combination At the same time, according to the use of temperature, medium and other different derived from the ALG-based hot water, high temperature corrosion-resistant chemical pumps, pumps. The series of products with high efficiency, low noise, reliable performance, etc., in line with the latest national Ministry of Machinery JB / T53058-93 standards, products according to the international ISO2858 standard design and manufacturing. Second, the main purpose 1. ISG vertical pipeline centrifugal pump for the transport 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 booster , Long-distance transmission, HVAC refrigeration cycle, heating and cooling water bath and other equipment and equipment, temperature T <80 ℃. 2. IRG-type vertical heat pump for metallurgy, chemicals, textiles, wood processing, paper and restaurants, bathrooms, hotels and other high-temperature hot water booster circulating transport and urban heating cycle pump, the use of temperature below 120 ℃. 3. GRG vertical high temperature centrifugal pumps are widely used: energy, metallurgy, chemicals, textiles, paper and restaurants, bathrooms, hotels boilers and other high-temperature hot water circulating pump circulation and urban housing heating circulation pump, the use of temperature below 240 ℃ . IHG vertical pipeline chemical pump for conveying solid particles, corrosive, viscosity similar to water, suitable for petroleum, chemical, metallurgy, power, paper, food and pharmaceutical and synthetic fiber and other departments, the use of temperature -20 ° C to 120 ° C. 5. YG vertical pipeline pump for the transport of petrol, kerosene, diesel and other petroleum products, the medium temperature is transported -20 ℃ ~ +120 ℃. 6. IHGB vertical stainless steel explosion-proof chemical centrifugal pumps, suitable for the transport of flammable chemical liquids. 7. ISGD, IRGD, GRGD, IHGH, YGD, IHGBD vertical low-speed centrifugal pumps for low noise environment requirements and air conditioning cycle and so on. Features 1. Pump for the vertical structure, import and export of the same caliber, and located in the same centerline, the same as the valve can be installed in the pipeline, the shape compact and beautiful, small footprint, Low investment in buildings, such as with the protective cover can be placed outdoors. 2. The impeller is directly mounted on the long axis of the motor, the axial dimension is short, the structure is compact, the configuration of the pump and the motor bearing are reasonable, the radial and axial loads generated by the pump operation can be balanced effectively, thus ensuring the smooth operation of the pump, Small vibration, low noise. 3. Seal with mechanical seal or mechanical seal combination, the use of imported titanium alloy seal, medium-temperature mechanical seal and the use of hard alloy materials, wear-resistant seal, can effectively extend the service life of mechanical seals. 4. Easy installation and maintenance, without moving the piping system, as long as you remove the pump seat nut can be pulled out all the rotor components. 5. According to the requirements of the use of flow and lift the need to use the pump string, parallel use. 6. According to the requirements of the pipeline layout using vertical and horizontal pump installation. Working conditions 1. Inhalation pressure ≤1.0MPa, or the maximum working pressure of the pump system ≤1.6MPa, that is suction inlet pressure + pump head ≤1.6MPa, pump static pressure test pressure ≤2.5MPa, please indicate the system work when ordering pressure. Pump system operating pressure greater than 1.6MPa should be separately ordered when ordering, in order to manufacture the pump overcurrent part and the coupling part of the cast steel material. 2. Ambient temperature <40 ℃, relative humidity <40%. 3. The conveying medium solid particles volume content does not exceed 0.1 per unit volume, particle size <0.2mm. Note: If the medium is with small particles, please specify when ordering, so that manufacturers use wear-resistant mechanical seal.
