Pipeline centrifugal pump I. Product Overview: ISG series single-stage single-suction vertical centrifugal pump is the second generation of high-efficiency energy-saving products designed by our company in accordance with the international ISO2858 and national standards JB/T6878.2-93, combined with the company's many years of production experience. SG-type pipe centrifugal pump, IS-type centrifugal pump, D-type multi-stage centrifugal pump and other conventional pumps ideal product. Series flow range 1.5 ~ 1600m3 / h, head range of 5 ~ 125m, sub-basic type, shunt type, cutting and other specifications. According to the different medium and temperature in use, the material change and structural change of the over-current part, design and manufacture of IRG-type hot water pump, IHG-type pipeline chemical pump, and YG-type pipeline oil pump with the same performance parameters can make this series of products widely used. Replace conventional centrifugal pumps for all applications. Features: 1 The pump is a vertical structure with the same inlet and outlet caliber and is located on the same center line. It can be installed in the pipeline like a valve. It has a compact and beautiful appearance, a small footprint, and a low construction investment. If a protective cover is added, it can be used. Place it for outdoor use. 2 The impeller is directly installed on the extension shaft of the motor. The axial dimension is short and the structure is compact. The pump and the motor bearing are configured properly, which can effectively balance the radial and axial loads generated by the pump operation, thus ensuring the smooth operation of the pump and vibration. The noise is very low. 3 shaft seal adopts mechanical seal or mechanical seal combination, adopts imported titanium alloy sealing ring, medium-sized high-temperature mechanical seal and adopts hard alloy, and wear-resistant seal, which can effectively increase the service life of mechanical seal. 4 installation and maintenance of instant noodles, no need to open the pipeline system, just remove the pump body nut can be extracted all the rotor components. 5 According to the requirements of use, that is, the flow and head need to use the pump string, parallel operation. 6 The vertical and horizontal installation of the pump can be used according to the piping layout requirements. Second, the model meaning: Third, the scope of use: 1. The ISG vertical centrifugal pump is used for conveying clean water and other liquids whose physical properties are like clear water, and the medium temperature does not exceed 80°C. Industry and urban water supply and drainage, pressurized water supply of high-rise buildings, garden sprinkler irrigation, fire booster, long-distance water supply, heating, bathroom and other warm and cold water circulation Pressurization and equipment support. 2, IRG vertical hot water circulation pump, suitable for energy, metallurgy, wood processing, chemicals, textiles, paper and restaurants, bathrooms, hotels and other boiler hot Water booster circulation and circulating pumps for urban heating systems use media temperatures not exceeding 120°C. 3, IHG vertical chemical pump, suitable for chemical, corrosive liquids such as textile, petroleum, chemical, pharmaceutical, sanitary, food, oil refining, etc. The medium temperature is -20°C to +120°C. 4. YG vertical pipeline oil pump is used to transport petrol, kerosene, diesel and other petroleum products. The medium temperature is -20°C～+120°C. Working conditions: 1 Absorption pressure ≤ 1.0Mpa, or pump system maximum working pressure 1.6Mpa, ie pump suction pressure + pump head ≤ 1.6Mpa, pump static pressure test pressure 2.5Mpa. (When ordering, please indicate the working pressure of the system. When the operating pressure of the pump system is greater than 1.6Mpa, it shall be separately stated at the time of ordering so that the overcurrent part and the joint part of the pump are made of cast steel material during manufacture.) 2 ambient temperature <40 °C, relative temperature <95%. 3 The volume content of solid particles in the conveyed medium does not exceed 0.1% of the unit volume and the particle size is >0.2mm. Note: If the media is used with small particles, please specify when ordering, so that manufacturers use wear-resistant mechanical seals. IV.
