Features, classification, and functions of pipeline pumps: Pipeline pumps are innovative pumps designed to increase pressure in pipelines and address the issue of low pipeline pressure; they offer significant advantages over the horizontal centrifugal pumps currently in use. Pipeline pumps have the following characteristics: 1. Pipeline pumps have a compact structure, with the pump and motor integrated together, resulting in a small size. Its vertical structure features a small installation footprint, stable operation, and no need for adjustments during installation. 2. The pump’s inlet and outlet are designed with flanges of the same specification and are aligned on the same center line, allowing it to be installed directly on the pipeline like a valve. Its low center position facilitates pipeline layout and simplifies installation. 3. The pump and motor are coaxial, resulting in a short axial dimension that enables smoother operation of the pump with lower noise levels. 4. The traditional shaft seal method is eliminated, preventing the leakage of the conveyed medium; thus, it features complete leaklessness. Function of pipeline pumps: Pipeline pumps are designed to increase pressure in pipelines and facilitate fluid transport; they are innovative pumps developed to address the issue of low pipeline pressure, and they offer significant advantages over the horizontal centrifugal pumps currently in use. The advantages of pipeline pumps are mainly reflected in the following aspects: 1. Pipeline pumps are suitable for pressurizing water supply in high-rise buildings, garden irrigation, feeding water to cooling towers, long-distance water transportation, air conditioning, refrigeration systems, bathrooms, and other applications that require cold water ； Warm water circulation for pressurization. Use at temperatures below 80°C. 2. Pipeline pumps are suitable for the pressurized circulation of high-temperature hot water in industries such as heating and boilers. Use at temperatures below 150°C. 3. Pipeline pumps are suitable for transporting corrosive media in the process streams of industries such as food processing, pharmaceuticals, winemaking, and chemicals, with an operating temperature below 80°C. 4. Pipeline pumps are suitable for transporting non-corrosive liquids, as well as in other industrial locations where explosive mixtures exist in temperature groups T1, T2, T3, and T4, such as in methane-containing environments or fixed equipment in coal mines of Class I, and in factories of categories IIA and II B. Use at temperatures below 80°C. 5. Pipeline pumps are suitable for transporting corrosive liquids in industries such as chemicals, pharmaceuticals, petroleum, food, and defense. They can be used in fixed installations in methane or coal mines of Category I, as well as in industrial facilities of Classes IIA and IIB. They are also applicable in other industrial locations where explosive mixtures exist in temperature groups T1, T2, T3, and T4. Use at temperatures below 150°C. Classification and application ranges of pipeline pumps The main series of pipeline pumps include low-speed pipeline pumps, vertical hot water pumps, shielded pipeline pumps, SG pipeline pumps, vertical pipeline oil pumps, and water-cooled low-noise pipeline pumps. 1. Low-speed pipeline pump, used for transporting clean water and other liquids with physical and chemical properties similar to those of clean water. It is suitable for industrial and municipal water supply and drainage systems, pressurizing water supply in high-rise buildings, garden irrigation, fire protection systems, long-distance water transport, HVAC systems, as well as for pressurizing hot and cold water cycles in bathrooms and other applications; the operating temperature should be below 80°C. 2. Vertical hot water pumps are suitable for use in metallurgy, chemicals, textiles, wood processing, papermaking, as well as in hotels, bathrooms, and guesthouses for the pressurized circulation of high-temperature hot water in boilers, and also for heating systems in urban residences; they can be used at temperatures up to 120°C. 3. Shielded pipeline pumps are widely used in the energy, metallurgy, chemical industry, textile sector, paper manufacturing, as well as in boilers for hot water in restaurants, bathrooms, hotels, etc., for pressurized circulation purposes; they are also used in pipeline systems for heating urban residential buildings, with operating temperatures up to 240°C. 4. SG pipeline pumps are used for transporting liquids that contain no solid particles, are corrosive, and have a viscosity similar to that of water. They are suitable for use in industries such as petroleum, chemicals, metallurgy, power generation, papermaking, food and pharmaceuticals, and synthetic fibers. The operating temperature range is from -20°C to 120°C. 5. Vertical pipeline oil pumps, used for transporting petroleum products such as gasoline, kerosene, and diesel; the temperature of the medium being transported ranges from -20°C to +120°C. 6. Water-cooled low-noise pipeline pump, suitable for transporting flammable chemical liquids.
