摘  要:
磁力泵的结构设计能否保证内磁转子体的轴向力平衡直接关系到泵的寿命。如何平衡磁力泵转子的轴向力是磁力泵设计的关键技术之一。该文以一高速磁力泵为例,介绍了高速磁力泵借助冷却回路结构设计进行轴向力平衡,提出按计算通式分段叠加求解的计算方法,总结了高速磁力泵轴向力平衡设计计算步骤。用该计算方法设计的高速磁力泵样机经实际试验验证,运行平稳、性能可靠。从而证明了该轴向力平衡设计计算方法的正确性。

摘  要:
In the structural design of a magnetic drive pump, the durability directly relates to the equilibrium of inner magnetic rotator. How to counteract the axial force is one of the key technologies. For the high-speed (magnetic) drive pump, the design for equilibrium of axial force is more important. Here an example is taken to (illustrate) the design of utilizing the cooling system to counteract the axial force, and a kind of calculation method is developed that the common formula proposed here is used to calculate and superpose for different segments. The calculation procedure of the axial force for the high-speed magnetic drive pump is summarized. The tested (results) show that the high-speed magnetic drive pump designed with this kind of axial force balance method runs smoothly and flexibly.
