Recently, our company's hydraulic universal testing machine was successfully debugged and tested at the customer's site. After being signed and confirmed by representatives of both parties, the technical parameters of the equipment comply with the contract agreement; Complete safety protection measures; The software functions run smoothly; The documents and materials (manuals, certificates of conformity, etc.) are complete. Comprehensive judgment: Passed the acceptance inspection and allowed to be put into use!
Hydraulic universal testing machine is a large-scale equipment widely used for testing the mechanical properties of materials. It mainly applies force through a hydraulic system and can perform various tests such as tension, compression, bending, and shear.
1. Basic structure
1.1 Host Framework
Usually, a double column or four column structure is used to ensure high rigidity and stability.Install the sample on the workbench and connect the hydraulic cylinder to the upper crossbeam.
1.2 Hydraulic system
Oil pump motor assembly: provides high-pressure oil.
Hydraulic cylinder: converts oil pressure into test force and drives piston movement.
Control valve: Adjust the direction, pressure, and flow of the oil circuit to achieve loading rate control.
1.3 Measurement and Control System
Force sensor: measures the force value that the sample is subjected to.
Displacement sensor: records deformation or displacement.
Controller: PLC or microcomputer system, set test parameters and collect data.
1.4 Attachments
Replace fixtures (such as tension clamps, compression bending devices, etc.) according to the type of experiment.
2.Main purpose
Material testing: strength, elastic modulus, plasticity index of metals, plastics, rubber, concrete, etc.
Quality control: Mechanical performance testing of products on industrial production lines.
Research and Education: Materials Research, Engineering Experiment Teaching.
