Operating speed test bearing is 2900r / min, the test bearing condition and other working conditions, test methods and procedures bearing performance is good or bad by any of the bearing friction torque, vibration and noise of the three physical quantities of one size testing. Bearing frictional torque is a power indicator, in theory, its size and voltage fluctuations can be driven by a magnetic force pump to display, but in fact, the voltage change in the early bearing failure, due to very small, high-power Magnetic pump drive can not reflect on the power supply; decanters bearing vibration can timely reflect the size of the bearing failure, but measurement requires a special system, expensive, and difficult to achieve in the field.

Our on-site magnetic pump bearing performance is good or bad by the noise test to determine the size of the bearing. In the long-term practice, we feel that this method is economical, practical and general early bearing failure can be detected. During the test, the sample will turn mounted in each magnetic pump, the bearing speed is always the same, the size of the bearing loads suffered by adjusting the position of loading block change.

By size of bearing noise to determine bearing is normal, after running for some time, some bearing noise changes, some bearing basically unchanged, recording the corresponding operation time, and remove bearing analysis in order to determine the bearing of good or bad.
