Fatigue testing machine is a kind of equipment widely used in many industries. It is easy to cause failures after long-term use, and normal maintenance is required to reduce the number of failures and extend the life. Since some users still don't know how to maintain and deal with the failure of the fatigue testing machine, this article will start from the daily failure response method and analyze it.

1. Cleaning issues

Cleaning the measuring instrument is a necessary task, because if there is too much dust on the measuring instrument, it will interfere with the measurement data and the accuracy of the measurement data cannot be guaranteed. Therefore, the operator must pay attention to the cleaning of the fatigue testing machine to ensure the measurement results of the testing machine.

2. Sample question

The problem in the measurement process of the fatigue testing machine is the wrong sample selection, which leads to various problems during the measurement process, which fails to meet the standard measurement requirements and causes the final data to be inaccurate. Therefore, before the measurement, the user must pay attention to the sample selection to ensure that the selected sample will not be inconsistent with the standard sample, which will affect the final measurement result.

3. Equipment measurement problems

Equipment measurement errors are mainly caused by many errors in the measurement process, such as the use of fixtures and loose screws. These issues are issues that many operators will ignore. Therefore, I want to remind you that you must pay attention to the measurement details, so as not to affect the measurement results, and the measurement requirements cannot be guaranteed, which will affect the enterprise.

The specific operations are as follows:

First, turn on the power switch, the switch does not light up

1. Power cord failure: check and repair the power cord;

2. The power supply voltage does not meet the requirements: provide a power supply that meets the requirements;

3. Power fuse open circuit: find out the cause of the fuse open circuit and replace the fuse with the same capacity.

Second, the fuse is repeatedly blown and cannot be used

1. Abnormal input voltage: replace the regulated power supply;

2. Abnormal or damaged motor: repair or replace the motor.

Third, the machine runs normally, the counter cannot count

1. Abnormal sensor induction: adjust the induction screw of the proximity switch to an appropriate position;

2. Sensor failure: replace the sensor;

3. Counter failure: replace the counter.

The fatigue dynamic testing machine mainly tests the physical properties of raw materials, finished products and semi-finished products. It can be used for tensile tests, pressure tests and bending tests to obtain test results and test data such as elongation, elongation, stress and strain. It can be used with different fixtures, accessories, two-point extenders and load cells for various tests, and can be connected to a computer-controlled machine tool platform.
