What requirements does the tensile testing machine have on the afterburner system?
No matter what kind of equipment has certain requirements during work or installation, the following editor will analyze the requirements of the tensile testing machine for the afterburner system with you, as follows: 1. Rigid testing machine frame of the testing machine The rigidity has been explained before, so I won’t repeat it here. 2. The tensile test space of the tensile testing machine requires different test spaces for the tensile test of different materials. Generally speaking, the tensile test space required for metal materials due to low ductility is not large, generally within 100mm; for non-metallic materials, especially The elongation of polymer materials is very high, and some are as high as 1000%. Therefore, the stretching space is relatively large, and the maximum stretching space is 1 meter. 3. The test fixture requires that at any position or during the test, the center line of the upper and lower chuck should be coaxial with the axis of the testing machine's afterburner, and its coaxiality: for the testing machine with a maximum capacity of not more than 5kN, it should not exceed 2mm/ 500mm; For testing machines with a maximum capacity greater than 5kN, the maximum allowable value of coaxiality is 15%; the chuck should be clamped reliably, not slipping, and can evenly clamp the sample; after the chuck removes the force or pulls off the sample, The jaws are not damaged; the jaws are interchangeable. 4. The horizontality of the moving beam of the tensile testing machine should be within 0.2/1000, and the movement should be stable within the working stroke, and there should be no side-to-side swing phenomenon. The speed of the moving beam and the allowable force shall meet the following requirements: For a testing machine with a maximum capacity not greater than 5kN, the maximum force of the testing machine should be applied at any speed; for a testing machine with a maximum capacity greater than 5kN: a. Moving If the speed is not more than 50mm/min, the maximum force value of the testing machine should be applied; www.laliceshiyi.comb. If the moving speed is greater than 50mm/min, the test force should not be less than 25% of the maximum force of the testing machine;

Next: Does the test result of the tensile testing machine have anything to do with the operator?
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.
