The pipeline centrifugal pump is a novel pump developed for pipeline pressurization and transportation to solve the problem of low pipeline pressure. It has great advantages over the horizontal centrifugal pump currently used. The advantages of pipeline pump are mainly reflected in the following points: 1. Pipeline pump is applicable to pressurized water delivery for high-rise buildings, garden sprinkler irrigation, cooling tower water supply, long-distance water delivery, air conditioning, refrigeration washing, bathroom and other cooling systems; Warm water is pressurized circularly, and the operating temperature is below 80 ℃. 2. It is applicable to high-temperature hot water pressurization cycle in heating, boiler and other industries. The operating temperature is below 150 ℃. 3. It is applicable to the transportation of corrosive media in the process flow of food, pharmaceutical, liquor making, chemical and other industries, with the operating temperature below 80 ℃. 4. It is applicable to other industrial sites where there are non corrosive liquids, methane or underground fixed equipment of coal mine Class I, factory Class IIA and IIB, temperature groups T1, T2, T3, T4, and explosive mixtures. The operating temperature is below 80 ℃. 5. The pipeline pump is suitable for conveying corrosive industrial liquids such as chemical, pharmaceutical, petroleum, food, national defense, etc. There are other industrial sites with explosive mixtures in groups T1, T2, T3, T4, such as methane or coal mine underground fixed equipment Class I, factory IIA, IIB. The operating temperature is below 150 ℃.
