In many centrifugal pump designs, the axial force is balanced by special balancing devices. Long cylindrical and short face throttles are the main constructive elements of such devices. The hydrodynamic characteristics of the cylindrical and face throttles depend on their geometry and operating parameters of the pump. The pressure distribution in the cylindrical throttle determines the pressure in the chamber of the automatic balancing device, the value of which affects the pressure distribution in the face throttle and the value of the resulting axial force. Since an automatic balancing device can be one of the most failure-prone components of centrifugal pumps, improving computational methods and designing such hydraulic units is still a significant problem. The Computational Fluid Dynamics method (Ansys CFX) is used to calculate the hydrodynamic characteristics of the traditional construction of the automatic balancing device. The pressure and velocity distributions are obtained. The value of axial force is calculated in a traditional balancing device. Some recommendations are given.
