Abstract

In order to control the wear of mechanical seal within the allowable range of leakage, it is very necessary to accurately collect the end friction torque.Through three groups of main bearing torque calibration tests, this paper analyzes and compares the relationship between the friction torque (or both fluid stirring friction torque) of the main bearing of the mechanical seal and the motor speed under different test conditions, and calibrates the friction torque of the main bearing in order to accurately obtain the friction power of the end face of the mechanical seal. The results show that the total power consumption is relatively small and changes little when the mechanical seal is running without load. The test results of noload operation test considering fluid mixing power consumption eliminate the influence of fluid mixing power consumption, which is more favorable and accurate for the subsequent measurement of mechanical seal performance test.
