What kinds of hydraulic universal testing machines are there
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. According to the force value, it is generally divided into four categories: 300KN, 600KN, 1000KN, and 2000KN. .
Hydraulic universal testing machine is divided into three types according to the control method: digital display (liquid crystal display) hydraulic universal testing machine, screen display (computer display) hydraulic universal testing machine, computer-controlled (automatic) hydraulic universal testing machine, according to the tightening method There are two general types: manual type and hydraulic type. Generally, hydraulic type is adopted.
Transmission system: The lower beam is driven by motor, cycloidal pinwheel reducer, sprocket and nut screw pair to realize the adjustment of stretching and compression space.
Testing machine level, level 1 accuracy requirement-the load sensor can meet the accuracy requirement by adopting high-precision oil pressure sensor. 0.5 accuracy requirement-the load sensor can meet the accuracy requirement by adopting spoke load sensor.
When using the hydraulic universal testing machine, we should pay attention to its use mode and distinguish its types, so as to better help us understand and use it.
