How to know whether the universal testing machine is used normally

How to check if the Universal Testing Machine is in normal use? Before answering this question, let's understand what are the functions of the universal testing machine and what industries use it! h4NTextile Testing Instruments, Testing Equipment Manufacturer

Universal testing machine, adjusted tension, bending, compression, shears, Ring stiffness and other functions in a materials testing machine, mainly used for mechanical performance testing of metals and non-metallic materials, is an ideal testing equipment for industrial and mining enterprises, scientific research units, colleges and universities, engineering quality monitoring stations and other departments. h4NTextile Testing Instruments, Testing Equipment Manufacturer

I saw that many companies have problems using The universal test machine is used for testing, but may be limited by the industry's obstacles, and the reason itself is not clear, resulting in untrue test results. Now would like I introduce some problems of equipment failure which are usually neglected, and I hope colleagues can add something to let the testing machine really play the role of quality control.h4NTextile Testing Instruments, Testing Equipment Manufacturer

Remember: it can still run there is no problem with the equipment! h4NTextile Testing Instruments, Testing Equipment Manufacturer

1. The test of power sensor present Blind spot: The general metrological check takes 10% or even 20% of the maximum load of the device as a starting pointof review, and many poor quality sensors are less than or equal to 10% and have a large error;h4NTextile Testing Instruments, Testing Equipment Manufacturer

2. There is instability in the moving speed of the bar: different experimental speeds lead to different same experimental results, so the speed must also be checked;h4NTextile Testing Instruments, Testing Equipment Manufacturer

3. Improper material selection of the manufacturer's moving beam: Especially in the case of large-tonnage metal tests, since the beam is also loaded at the same time, it will deform, which will also affect the test results. So it is better to choose a good steel casting material. If it is a cast iron material, it can even be overloaded and break directly;h4NTextile Testing Instruments, Testing Equipment Manufacturer

4. Installation position of the displacement sensor: Due to the design, the installation position of the displacement sensor is different: but the installation is on the screw rod side better than installing it on the engine h4NTextile Testing Instruments, Testing Equipment Manufacturer

5. Universal testing machine The coaxiality (neutrality) is ignored: it can be the reason for the difficulty of the test Almost nobody examines the coaxiality of the device, but if there is a problem with the coaxiality, it must be It will affect the experimental results, especially in some small stress tests. I saw that the base of the bracket is not fixed in the test, and the reliability of the data is clear at a glance;h4NTextile Testing Instruments, Testing Equipment Manufacturer

6. The problem of the jig: After long-term use, the jaw of the jig will be worn, chipped and deformed, resulting in unreliable clamping or damage to the specimen, affecting the final result of the jig test;

7. The effects of synchronous belts or reduction gears: When the equipment in the production process is not careful enough, it will accelerate the aging life of these two parts, which is not the case. If it is replaced in time, it will affect the results of the experiment;

8. The failure of the safety protection device: The consequences may damage the device directly. It is recommended to check it regularly, since some software mayre be caused. Caused by malfunction, be careful to sail thousands of years.h4NTextile Testing Instruments, Testing Equipment Manufacturer
