Many users are often hesitant about the choice of pipeline centrifugal pumps, mainly because new users do not know the pipeline pump and sometimes do not even know where to start. As the pipeline centrifugal pump in the chemical, metallurgical, drainage and other fields to use more and more density, its demand is also more than ever before, then the pipeline centrifugal pump should be how to choose it? Next, we will provide several pipeline centrifugal pump selection of the reference direction. Pipeline centrifugal pump selection 1, must meet the requirements of the use of flow and lift, which requires the pump operating point (device characteristic curve and pump performance curve of the intersection) often remain in the high-efficiency range of operation, so that both power and not easily damaged Mechanical parts. 2, the selected pump should not only small size, light weight, low cost, but also have good characteristics and high efficiency. 3, with good anti-cavitation performance, so that both to reduce the depth of the excavation of the pump room, without pump cavitation, smooth operation, long life. 4, according to the selected pumping station, less investment in engineering, low operating costs. In this economy and society, more and more people buy products not only care about the quality of the products, but also pay more attention to product prices and after-sales service. This not only increases the difficulty of purchasing and selecting products, but also poses more work challenges for the merchants. In summary, in the selection of pipeline centrifugal pumps, we not only have to consider the use of pipeline centrifugal pumps, work conditions, but also to meet the economic, security, applicable principles.
