Carbon alloy steel hydraulic universal testing machine

Carbon alloy steel hydraulic universal testing machineIt is an important instrument and equipment for testing the physical properties, mechanical properties, process performance, structural seismic strength, and internal and external defects of various materials and their products in various environments and simulated states. It is possible to conduct tensile, compressive, bending, shear and other types of tests on metal or non-metal materials according to corresponding standards. Performance indicators such as tensile strength, yield strength, specified non proportional elongation strength, elastic modulus, etc. of the tested material can be obtained. It is possible to achieve closed-loop control such as constant rate loading, constant rate deformation, constant rate displacement, constant rate strain, etc. It is also possible to conduct process qualification performance verification tests on materials or products.

Carbon alloy steel hydraulic universal testing machineyesThe series testing machine is designed and manufactured according to the national standard GB/T 16826-2008 "Electro hydraulic Servo Universal Testing Machine". It is a combination model of E-type host, servo control oil source, and microcomputer automatic control system. It consists of six parts: dual space testing machine host, servo oil source, chuck oil source, fully digital measuring and control device, manual control box, and computer system.

The host adopts a high stiffness design, and each load-bearing component undergoes finite element analysis, design, precision machining, and testing. The oil source system adopts a load adaptive throttling speed regulation system, which has undergone repeated pressure tests and maximum load holding tests. The controller adopts a new generation of high-performance, intelligent fully digital independent controller. The measurement and control software adopts a combination of excellent measurement and control algorithms, which can accurately control the entire experimental process and meet the requirements of domestic and international material testing methods.

Mainly used for tensile, compressive, bending and other mechanical performance tests of metal, non-metal, structural components, concrete, ceramics and other materials. Measure performance parameters such as ReH yield strength, ReL yield strength, Rp specified non proportional tensile strength, Rt specified total tensile strength, Rm tensile strength, Rr specified residual tensile strength, and E elastic modulus.

structural composition

Host: It usually adopts a bottom mounted or four column structure with oil cylinders, including columns, crossbeams, clamps, pressure plates and other components. The tensile space is located above the host, and the compression, bending and other testing spaces are located between the bottom crossbeam of the host and the workbench.

Hydraulic system: composed of oil tank, oil pump, motor, servo valve, relief valve, electromagnetic directional valve, etc., providing stable hydraulic power for the test, controlling the flow and pressure of the oil, and achieving precise control of the test force and displacement.

Measurement system: including high-precision load sensors, grating rulers, encoders, extensometers, etc., used to measure parameters such as force, displacement, and deformation of the specimen.

Control system: generally composed of computers, control software, DCS controllers, etc., it can achieve automated control of the experimental process, set experimental parameters, display and record data in real time, and perform data processing and analysis.
