Overview

The 300KN electro-hydraulic servo universal testing machine (model WAW-300D) is an equipment used for testing the mechanical properties of metal and non-metal materials. It is mainly used for tensile, compression, and bending tests and is widely used in various industries such as building materials, roads, steel, and automobiles. Its main engine adopts a cylinder bottom structure, which meets the requirements of national standards such as GB/T16826-2008. The manufacturing and inspection follow standards such as GB2611 and JJG139, and the testing methods meet the data processing needs of hundreds of standards such as GB/T228, GB/T7314, and GB/T232

Product Details

300KN electro-hydraulic servo universal testing machine

Suitable for fields such as steel, metallurgy, construction, military industry, colleges and universities, research institutions, etc. The common model of this device is WAW-300D, with a maximum test force of 300kN (approximately 30 tons) The host usually adopts a four column, two screw, and oil cylinder downward structure, forming a double testing space above and belowThe measurement and control system adopts a fully digital multi-channel closed-loop measurement and control system, supporting three closed-loop control of stress, strain, and displacementThe experimental operation and data processing meet the requirements of metal stretching, compression and other standards. The control system supports multiple types of tests such as tension, compression, shear, and bending, and has the ability to edit test steps and standards This device complies with the requirements of hundreds of national standards such as GB/T228 "Tensile Test Method for Metallic Materials at Room Temperature", GB/T7314 "Compression Test Method for Metallic Materials at Room Temperature", GB/T232 "Bending Test Method for Metallic Materials", etc .

working principle

The working principle of the 30 ton electro-hydraulic servo hydraulic universal testing machine is based on the electro-hydraulic servo system and closed-loop control system, achieving precise loading and data acquisition of the sample.

Electro-hydraulic servo systempasselectro-hydraulic servo valvecontrolhydraulic cylinderThe movement of the sample enables precise loading, providing stable, continuous, and controllable loading force.

The equipment adopts a fully digital multi-channel closed-loop measurement and control system, which has three closed-loop control functions of force, deformation, and displacement, and can monitor and automatically adjust the parameters during the loading process in real time.

Equipped with various sensors such as force sensors, displacement sensors, and deformation sensors, real-time mechanical performance data of the sample is collected, and performance indicators such as tensile strength, yield strength, and elastic modulus of the material are automatically obtained through measurement and control software.

characteristic
