What are the classifications and uses of hydraulic universal testing machines?
Hydraulic universal testing machine A hydraulic material testing machine that can perform various tests such as tension, compression, and bending. The hydraulic universal testing machine is used for tensile, compression, bending and shear tests of various metal and non-metal materials, as well as special tests of some products. The test operation and data processing comply with GB228-2010 'Metal Tensile Test Method for Room Temperature Materials' And other standard requirements. Hydraulic universal testing machine is mainly used for tensile, compression, bending, shearing and other mechanical performance tests of metal, non-metal, composite materials and products. At the same time, it can be used in accordance with GB, ISO, JIS, ASTM, DIN and many user-provided tests. A standard for testing and data processing. It is widely used in material inspection and analysis in aerospace, machinery manufacturing, wire and cable, rubber and plastic, building materials and other industries. It is an ideal testing equipment for scientific research institutes, universities, industrial and mining enterprises, technical supervision, commodity inspection and arbitration and other departments. Hydraulic universal testing machines are generally divided into four categories, 1100KN, 300KN, and 600KN000KN, which are relatively simple compared to a wide range of electronic universal testing machines; hydraulic universal testing machines are technically refined into three categories and a total of 12 conventional types: Digital display (liquid crystal display) hydraulic universal testing machine: 100KN, 300KN, 600KN, 1000KN. Screen display (computer display) hydraulic universal testing machine: 100KN, 300KN, 600KN, 1000KN. Microcomputer control (automatic) hydraulic universal testing machine: 100KN, 300KN, 600KN, 1000KN. According to the tightening method, there are two general types: manual and hydraulic. According to the screw adjustment method, it is divided into (the most common): chain type and worm gear type. According to the equipment grade, it is divided into: B-type machine, C-type machine, D-type machine, E-type machine and A-type machine in the 90s (which has been eliminated). Note: Except for model A, B, C, and D are all main engines with under-cylinders.

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.
