Abstract: Aiming at the high precision and stability requirements of the liquid rocket engine high-speed centrifugal pump water test system,a small-range torque field calibration device based on the principle of casual balance was developed.The realization principle,technical index and overall design of the whole set of calibration device are introduced.The key technology and test verification of the torque field calibration device design are mainly introduced.The verification results show that the device meets the design index requirements and meets the field calibration application requirements.

Key words: Torque, Field calibration, Neutral equilibrium, High-speed centrifugal pump
