1.Double suction pump has a better balance of the role of axial thrust; next, through the analysis of the characteristics of the double suction pump:
2.Double suction pump is not prone to cavitation;
3.Double suction pump mouth ring is more likely to leak;
4.Double suction pump running smoothly;
5.Double suction pump cavitation allowance should be lower, but the efficiency is lower;
6.From the structure, the double suction pumps are mostly made of BB2, BB1 type;
7.Double suction pump in the balance of the axial force has a great advantage;
Through the research and analysis of the above points, it can be concluded that the double suction pump is characterized by good balance force, high lift, large flow, stable operation, and is not prone to cavitation, but its main problem is low efficiency. Along with the rapid development of China's economy, the centrifugal pump the challenge is greater, the centrifugal pump double suction pump, it is facing more difficult, at present its use scope or subject to certain restrictions, in order to break the boundaries of all walks of life, much more work needs to be done.
