Briefly analyze the difference between electronic universal testing machine and hydraulic universal testing machine

Electronic universal testing machineandHydraulic universal testing machineThey are all material mechanical testing instruments, but they have their own characteristics in terms of structural design, performance, application scope, etc. Users can decide whether to choose an electronic universal testing machine or a hydraulic universal testing machine based on the specific usage environment of the industry. The difference between electronic universal testing machine and hydraulic universal testing machine is as follows: 1. In terms of structural characteristics
There are currently two main forms of electronic universal testing machines, synchronous belt and reducer; in terms of force measurement, both electronic universal testing machines use load sensors.
Hydraulic universal testing machines mainly use high-pressure hydraulic sources as power sources, while electro-hydraulic servo universal testing machines use servo valves or proportional valves as control components for control. Some domestic manufacturers have also used high-precision load sensors to measure force.
2. In terms of performance
Electronic universal testing machine does not use oil sources, so it is cleaner and more convenient to use and maintain; its test speed range can be adjusted, the test speed can reach 0.001mm/min - 1000mm/min, the speed ratio can reach 1 million times, the test stroke can be determined according to needs, and it is more flexible; the force measurement accuracy is high, and some can even reach 0.2%; it is small in size, light in weight, large space, and convenient to use corresponding devices to perform various material mechanics tests, truly achieving multiple uses in one machine. Currently, the electronic universal testing machines produced by mainstream domestic testing machine manufacturers can all achieve the so-called three-closed loop control of load control, strain control, and displacement control.
Hydraulic universal testing machine has a low test speed due to the limitation of oil source flow. The manual hydraulic universal testing machine is relatively simple to operate and cheaper, but has low control accuracy; the electro-hydraulic servo universal testing machine has a low performance, in addition to its low speed, and control accuracy is not inferior to that of the electronic universal testing machine.
3. In terms of application scope
Electronic universal testing machine is widely used in various metals, non-metals and composite materials, such as wood, plastic profiles, wires and cables, paper, films, rubber, medicine, food packaging materials, fabrics, etc. for testing tensile performance indicators and digital display electronic universal testing machine is suitable for users who only seek relevant data such as force value, tensile strength, compressive strength, etc. If you need to take more complex parameters, it is a better choice for microcomputer-controlled electronic universal testing machine.
In terms of cost performance, electronic universal testing machines below 30T have more advantages. Hydraulic universal testing machine is mainly used for mechanical properties such as tensile, compression, bending, etc. of metals, non-metallic materials and parts, components and components. The hydraulic universal testing machine is an ideal testing equipment for industrial and mining enterprises, construction materials, quality inspection centers, water conservancy and hydropower, bridge engineering, scientific research institutes, and mechanics laboratory of colleges and universities. The electro-hydraulic servo universal testing machine is suitable for steel and building materials testing laboratories with higher requirements. Compared with electronic universal testing machines with electro-hydraulic servo universal testing machines above 30T, they have more price advantages.http://www.hssdtest.com/
