What are the reasons for the inaccurate test results of the tensile testing machine?
The testing machine is a relatively precise mechanical testing instrument, which is widely used in various industries. It is inevitable that the equipment will have some failures after a certain amount of use, and one of them is also a very common testing machine in various industries-the same is true for the tensile testing machine. One of the more common problems is that the measurement data is inaccurate or the measurement value is too large during the test using the tensile testing machine. So how do we solve this problem? Today, I will give you a specific introduction to the processing method of the inaccurate measurement data of the tensile testing machine. I hope it can help you. 1. There is no zero-return operation at the beginning of the test, and the test will start if it is not zero-returned, so the test result is inaccurate. 2. After the sensor is used for a certain period of time, the strain undergoes elastic buckling and does not return. In fact, this strain is very small. Generally, the coefficient of the force sensor must be recalibrated in one year to correct the data. 3. If the sample is not clamped correctly during the test, the test result will be inaccurate. 4. The test speed during the test is not standard, too fast or too slow will cause the test results to be different. 5. The force sensor is damaged when it is impacted by an external force or used over capacity. For more technical information about the testing machine, please refer to the Chenda website. Welcome new and old customers to visit the factory and purchase the testing machine suitable for you!

Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
