Abstract:
                                      Axial force is one of the important factors that affect the stable and safe operation of centrifugal pump. In order to deeply analyze the influencing factors of axial force of centrifugal pump, this paper discusses the causes of axial force of centrifugal pump and the research progress of its calculation, and summarizes several basic methods of balancing axial force. The influences of various factors, such as balance hole, balance drum or balance plate, impeller back blade, sealing ring, axial clearance of pump cavity and cavitation, etc. The axial force of centrifugal pump are mainly introduced, and the related literature is summarized for further discussion. Based on the research of many experts and scholars, the paper finally summarizes and proposes the research emphases and improvement aspects of axial force balance of centrifugal pump.
