Double-inlet pump double suction pump features

[Asia Fluid Network News] With double suction pump in industrial production has been widely used. Double suction pump is composed of two back to back impeller combination, the flow of water from the impeller into a volute. Double suction pump has the following characteristics: it is equivalent to two single-suction impeller of the same diameter at the same time work at the same impeller diameter flow can be doubled; pump shell level in the open, easy inspection and maintenance, while double Pump inlet and outlet in the same direction and perpendicular to the pump shaft, which will help pump and out of the water pipe layout and installation; double suction pump impeller structure is symmetrical, there is no axial force, the operation is relatively stable. Double suction pump is there are two suction chamber, pump suction inlet and inlet are vertically below the axis. The main impeller or water direction. Double suction pump benefits is the same speed and flow, due to reduce the inlet flow rate, the pump is not prone to cavitation. Double-suction pump double suction pump features 1, double suction pump better balance the axial thrust; followed by a few analysis of double suction pump features: 2, double suction pump is not prone to cavitation; 3, double Suction pump mouth ring more easily leak; 4, double suction pump running smoothly; 5, double suction pump NPSH lower, but efficiency is lower; 6, from the structure, the double suction pump mostly do Into BB1, BB2 type; 7, double suction pump in balancing the axial force has a great advantage; after the above points of research and analysis can be drawn that the double suction pump is characterized by good balance, high head, flow, operation Smooth, not prone to cavitation, but its main drawback is the low efficiency. With the rapid development of China's economy, centrifugal pumps are also challenged with greater challenges. For the double-suction pump in centrifugal pumps, it is more and more difficult. At present, its scope of application is still limited. In order to break this boundary, all circles There is still a lot of work to do.
