Creep fatigue testing machine is an important equipment used to test the performance of materials under high temperature and alternating loads. Its maintenance and fault diagnosis are crucial to ensure the accuracy of test results.

routine maintenance

Cleaning and Inspection: Regularly clean the surface dust of the testing machine to prevent dust from interfering with measurement data. Check the clamping force and cleanliness of the fixtures to ensure that appropriate fixtures are used for testing different materials, and to avoid affecting the test results due to wear or rust.

Motor maintenance: The motor is a critical component of the testing machine, and frequent use may result in excessive temperature. Regularly check the temperature, vibration, and internal wires of the motor to ensure cleanliness and normal operation.

Sensor calibration: Sensors are components in testing machines that are prone to problems, and overloading may cause damage. Regularly calibrate sensors to ensure their sensitivity and stability, and replace them if necessary.

Sheet metal protection: Sheet metal is the outer protective layer of the testing machine to prevent oxidation and corrosion of the machine. If the sheet metal is scratched, it should be repaired in a timely manner to avoid corrosion caused by impurities such as water.

fault diagnosis

Power failure: If the power switch does not light up, check if the power cord is faulty and if the power fuse is open. After identifying the cause, replace the fuse with the same capacity or repair the power cord.

Repeatedly burning the fuse: It may be due to abnormal input voltage or motor, and the voltage regulator needs to be replaced or the motor needs to be repaired/replaced.

Counter unable to count: Check if the sensor sensing is normal, adjust the sensing screw of the proximity switch to the appropriate position; If the counter malfunctions, it needs to be replaced.

Abnormal operation with loud noise: It may be due to motor failure or bearing failure in the running part, and the motor or bearing needs to be repaired or replaced.

The device cannot load: It may be due to low power supply voltage or hardware damage, and the power supply voltage needs to be adjusted or the damaged hardware needs to be replaced.
