What is the essential difference between electronic universal testing machine and hydraulic universal testing machine
The electronic universal testing machine and the hydraulic universal testing machine are largely the same in terms of functions, but we also know that the functions of the two are different. PleaseJinan Hengsi Shanda Instrument Co., Ltd.Let’s talk about the differences in the functions of electronic universal testing machines and hydraulic universal testing machines.
, from the perspective of usage functions:
Electronic universal testing machine, no oil source. Therefore, 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, and the test stroke can be determined according to needs, making it more flexible. The force measurement accuracy is high, and some can even reach 0.2%. It has small size, light weight and large space, making it convenient to add corresponding devices to perform various material mechanical tests. It really achieves multiple uses in one machine. Currently, the electronic universal testing machines produced by mainstream domestic testing machine manufacturers can all achieve load control, strain control, and displacement control so-called three-closed loop control.
Second, from the perspective of structural characteristics:
The electronic universal test machine mainly uses a servo motor as the power source, and the lead screw and wire master as the execution components to realize the speed control of the moving beam of the test machine. In terms of transmission control, there are currently two main forms, synchronization belt and reducer. The advantages and disadvantages are still to be discussed, but they do not affect users' use. In terms of force measurement, all electronic universal testing machines use load sensors.
Hydraulic electronic universal testing machine, as the name implies, uses high-pressure hydraulic source as the power source. Manual valve, servo valve or proportional valve are used as control elements for control. Ordinary hydraulic universal testing machines can only be loaded manually and are open-loop control systems. Affected by price factors, the force sensor generally uses hydraulic pressure sensors. Electro-hydraulic servo universal material testing machines use servo valves or proportional valves as control components for control, and some domestic manufacturers have also used high-precision load sensors to measure force.
3. From the perspective of scope of use:
Electronic universal testing machine is widely used in various metals, non-metals, composite materials, medicine, food, wood, copper, aluminum, plastic profiles, wires and cables, paper, film, rubber, textile, aerospace and other industries to conduct tensile performance indicator testing. At the same time, various test data processing software and test auxiliary tools can be customized according to domestic and international standards provided by users. Digital display electronic universal testing machine is suitable for users who only seek relevant data such as tensile strength and compressive strength. If you need to take more complex parameters, a microcomputer-controlled electronic universal testing machine is your better choice. In terms of cost performance, electronic universal testing machines below 30T have more advantages.
Hydraulic universal testing machine is mainly used for mechanical properties tests such as tensile, compression, bending, etc. of metal and non-metallic materials and parts, components, and components. The hydraulic universal testing machine is an ideal testing equipment for engineering, mining enterprises, construction and building materials, quality inspection centers, water conservancy and hydropower, bridge engineering, scientific research institutes, and mechanics laboratory of colleges and universities. Manually controlled hydraulic universal testing machine is cheap and suitable for finished product inspection and single material index testing of industrial and mining enterprises. Electro-hydraulic servo universal material testing machine is suitable for steel and building materials testing laboratories with higher requirements. Electro-hydraulic servo universal material testing machines with an electro-hydraulic servo universal material testing machines above 30T have more price advantages than electronic universal test machines.
Through the introduction given to us above, the many differences between the two can also make us clearly understand what kind of engineering and what kind of test machine to use.
