How to measure the tensile force of the testing machine
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. It is more cumbersome to calculate the tensile force value, so in order to simplify the complex and cumbersome calculation procedures, the test The machine came into being. How does the testing machine measure the tensile force? With this question, let's take a look at the following content. The calculation of the force value of the testing machine is mainly based on the force value of the testing area of u200bu200bthe testing machine. First, put the test product to be measured on the workbench, and let the testing machine perform the stretching operation on the tensile specimen at the speed of the GB/T228-2002 standard specification. At this time, an extensometer or strain gauge should be installed on its surface, so that the testing machine will continue to stretch the tensile specimen. The extensometer or strain gauge will display the tensile strength of the tensile specimen, and then the extension can be extended. The amount is converted into a tensile value, and then compared with the value displayed on the dial of the testing machine, and the calculation of the testing machine is determined according to the difference of the comparison value. This method of comparison can also be related to Hooke's law. Calculation, this method of comparison can help to find the accuracy of the testing machine, and it can also simplify the cumbersome process due to multiple operations, which not only improves the test efficiency, but also the test results are more credible.
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.
In order to prevent accidents, safety protection devices are installed in the design of the testing machine.
