company news about Tension testing machine to the operator what requirements

Tensile testing machine is widely used in the production and scientific research of plastics, rubber and other raw materials and products, suitable for chemical production enterprises, universities and research institutes to measure the mechanical properties of materials, mainly used for testing plastic film, fabric, leather, monofilament, metal foil and other materials. In the process of using the testing machine, users understand some of the use of professional terms, it is very important for the safe use of tensile testing machine in the future.

 tensile range

according to the load of the material being measured, select the load required by the testing machine (that is, the range). It is recommended that the material test load should be about 70%-90% of the range of the tensile testing machine to ensure the test resolution and extend the service life of the testing machine. So in the choice of tension machine, not the bigger the better, but suitable for your product strength range.

 accuracy level

general material test choose 1 level testing machine is sufficient, scientific research and material analysis need 0.5 level testing machine; In fact, 0.5 and 1 level precision testing machine has no obvious technical difference, the verification methods and means are basically the same, is the difference of the correction point. With the development of sensor technology, the linearity of sensor components has reached a high level. As long as the measurement circuit has no defects, anti-interference performance is good, all the testing machines to achieve 0.5 accuracy is no problem.

Tensile testing machine before the use of these preparations

1. Device

Before using the test machine, effective professional installation is very necessary, because only through the correct installation, the equipment can operate normally in the process of use, so as to ensure the final use effect.

2. Instructions

Be sure to understand the installation and use instructions in detail, and keep them properly after detailed reading for future reference and use, but also to ensure the accuracy of the use method.

3. Check and test the machine

Pay attention to the inspection of equipment. After the device is used, the position of each part of the device may not be standard, or the fault of one part of the device will cause problems in the measurement of the device.

4. Place standard lines

When measuring the sample, attention should be paid to the standard line to ensure the accuracy of measurement. If the standard line is not placed in the standard place, it will certainly affect the measurement.

5. Avoid adjustments

Tensile testing machine in the process of measurement, prohibit arbitrary adjustment, because the equipment has been working. If you adjust the device, the measurement results will be affected and the device may be blocked, resulting in test failure. So be careful not to arbitrarily adjust the device anywhere.
