Four ball friction testing machineTimely troubleshooting can ensure the accuracy of test data and equipment stability, as faults may occur due to operation, wear and tear, or environmental factors during long-term use.

1、 Common faults and troubleshooting methods

Fault 1: Abnormal fluctuation of friction torque data

Check if the load is stable and recalibrate the load sensor; Check if the installation of the sample ball is symmetrical and if there is any oil or damage on the surface.

Fault 2: The spindle cannot rotate normally

Check if the motor power connection and wiring are intact; Check if the transmission components are stuck, add lubricating oil or replace worn transmission components.

Fault 3: Large deviation in wear spot measurement results

Confirm that the parameters such as test temperature and speed meet the standards; Check the focusing accuracy of the microscope, clean the lens and the surface of the sample ball.

Fault 4: Equipment alarm prompts a fault

Interpret the alarm code according to the equipment manual, and focus on investigating triggering conditions such as overload protection and temperature exceeding limits; After restarting the device, the error still occurs and the corresponding components need to be repaired.

2、 Core principles for investigation

First, investigate external factors such as power supply, environment, and operating procedures, and then check the internal components of the equipment.

When unfamiliar with mechanical structures, avoid disassembling core components without authorization and prioritize contacting professional maintenance personnel.

After troubleshooting, a no-load test is required to verify whether the equipment has returned to normal.
