A testing machine, in a broad sense, 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. It can be seen from the definition that any instrument that verifies quality or performance can be called a testing machine, but it is sometimes also called a tester, a tester, a tensile tester, a tester, a tester, etc. In the textile industry it is customary to call it a powerful machine, which is actually a tensile testing machine. The testing machine is mainly used to measure the physical properties of materials or products, such as the yield strength and tensile strength of steel, the hydrostatic time determination of pipes, and the fatigue life of doors and windows. The one used to measure the chemical properties of materials is also the chemical composition, which is generally called an analyzer, not a testing machine.
The concept and use of the testing machine The testing machine is a precision test to determine the mechanical properties, process performance, internal defects, and check the dynamic imbalance of rotating parts under various conditions and environments, such as metal materials, non-metal materials, mechanical parts, engineering structures, etc. instrument. In the process of researching and exploring new materials, new processes, new technologies and new structures, the testing machine is an indispensable important testing instrument. It is widely used in machinery, metallurgy, petroleum, chemical industry, building materials, construction, aerospace, shipbuilding, transportation, and other industrial departments, as well as related laboratories in universities and research institutes. It plays an important role in effectively using materials, improving processes, improving product quality, reducing costs, and ensuring product safety and reliability.
The testing machine industry mainly produces the following eight types of products: 1. Metal material testing machine; 2. Non-metal material testing machine; 3. Force and deformation testing equipment (force sensor, dynamometer, displacement sensor, extensometer, accelerometer, etc.) ); 4. Packaging and process performance testing machines (including packaging drop testing machines, packaging impact testing machines, friction and wear testing machines, bending testing machines, straightening machines, etc.); 5. Balancing machines (including on-site balancers) ); 6. Vibration table (including impact table and collision test table); 7. Non-destructive testing equipment (magnetic particle flaw detector, X-ray flaw detector, gamma ray flaw detector, ultrasonic flaw detector, eddy current flaw detector, acoustic emission detector, etc.) ; 8. Testing machine functional accessories and testing equipment and equipment related to the testing machine.
