The electronic testing machine uses a stepping motor as the power source, and the single-chip microcomputer displays the test data and test status in real time, and the control of the testing process is realized through the automatic control of the single-chip microcomputer.
It can test and analyze the mechanical properties of various non-metallic and composite materials, and is widely used in aerospace, petrochemical, engineering, wire, cable, textile, fiber and plastic , rubber, ceramics, food, pharmaceutical packaging, aluminum-plastic pipes, plastic doors and windows, geotextiles, foils, wood, paper and other manufacturing industries.
The electronic testing machine adopts electromechanical integration, and the product has the advantages of stable performance, safe and reliable use, and easy maintenance.
Users must have some level of product knowledge when using it. The following editor introduces the use and features of the electronic testing machine in detail, hoping to help users to better apply the product.
The electronic testing machine features hydraulic loading, easy to operate, has digital display force measurement, accurate and reliable test data, and can be used for tension, compression, bending and shear of general steel and steel are used other metal materials. It can also be used for compression and flexure testing of general materials, plastics, cement and concrete.
To ensure the accuracy of the testing machine readings, a digital force gauge (or computer) is used. In order to prevent the vibrations that occur when the specimen breaks, the accuracy of the load cell is increasednot affected by this. The main body and control box (including force gauge or computer) are divided into two independent parts.
After using the electronic testing machine for a long time, you will feel that the testing machine is not accurate. Now let's summarize the solution to this problem.
When we use electronic testing machines to perform tensile tests on materials, we inevitably encounter various problems. But if we fixed it and it still has various problems, then that means we haven't fixed it completely.
At this point, we should conduct a comprehensive observation, inspection, and troubleshooting. It cannot be put into service until it is fully repaired. So are there any other places worth re-examining and troubleshooting?
Check one to see if the Lastsensor default is:
General measurement verification uses 10% or 20% of device load as verification initial value, and many poor quality load sensors happen to have larger error below ≤ 10%.
If there is indeed a problem with the accuracy of the load cell, we should replace it in time.
Check 2. Whether the speed of the beam is normal:
The results of the electronic testing machine tensile test are different at different speeds, so need to test speed checks are carried out.
Check three, the measuring range is not sufficient:
Estimate whether the material force value exceeds the tensile test. If the range of the electronic tensile testing machine is exceeded, exchange Please hand out the test material.
Check 4. whether the installation position of the displacement sensor is correctis:
Because the construction is different, the mounting position is also different: but those mounted on the side of the threaded rod are more accurate than those mounted on the engine.
Check five whether the timing belt or deceleration device is damaged due to the extension of the service life:
With the extension of the service life of the timing belt or the Delay device accelerate the aging time of these two parts, and if they are not replaced in time, the test results will be affected.
Check six whether the safety protection device fails:
If the safety protection device fails, it will directly affect the electronic testing machine , we should check it regularly .
