Last post we have introduct the Difference Between Electronic Testing Machine And Hydraulic Electronic Testing Machine in structural characteristics, this post we will continue to introduce
- The electronic universal testing machine mainly uses the motor as the power source, plus the reducer, frequency converter, screw, gear chain, etc. as the executive components to realize the movement of the beam. Because it does not use the oil source, 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 the needs, which is more flexible.
- All electronic universal testing machines use load sensors in force measurement. If you need more complex parameters, the microcomputer-controlled electronic universal testing machine is your better choice. In terms of cost performance, the electronic universal testing machine is more advantageous if the power is within 30T.
- The hydraulic universal testing machine uses a high-pressure hydraulic source as the power source. Use manual valve, servo valve or proportional valve as control element for control. Ordinary hydraulic universal testing machine can only be manually loaded manually, which belongs to an open-loop control system. Affected by price factors, the force sensor generally uses a hydraulic pressure sensor. The electro-hydraulic servo universal material testing machine uses servo valves or proportional valves as control components for control. Some domestic manufacturers have also adopted high-precision load sensors to measure force. Electro-hydraulic servo universal material testing machines are suitable for more demanding requirements. High steel, building materials testing laboratory. Compared with electronic universal testing machines, electro-hydraulic servo universal testing machines above 30T have a price advantage.
- The hydraulic universal testing machine is limited by the flow rate of the oil source, so its testing speed is low. Manual hydraulic universal testing machine, the operation is relatively simple, the price is cheap, but the control accuracy is low. The performance of the electro-hydraulic servo universal testing machine is compared with that of the electronic universal testing machine. In addition to the low speed, the control accuracy will not be bad. The microcomputer-controlled electro-hydraulic servo universal testing machine with load cell can achieve a force value accuracy of about 0.5%. . And it is more reliable, more stable and more cost-effective when doing large-tonnage material mechanics tests.
- Electronic universal material testing machine, widely used in various metal, non-metal, composite materials, medicine, food, wood, copper, aluminum, plastic profile, wire and cable, paper, film, rubber, textile, aerospace and other industries For testing of tensile performance indexes, various test data processing software and test aids can be customized according to the domestic and international standards provided by users. The 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, the computer-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 material testing machine is mainly used for tensile, compression, bending and other mechanical performance tests of metal, non-metallic materials and parts, components, and components. The hydraulic universal testing machine is an ideal testing equipment for the mechanics laboratory of industrial and mining enterprises, construction materials, quality inspection centers, water conservancy and hydropower, bridge engineering, scientific research institutes, and universities. The manually controlled hydraulic universal testing machine is cheap and suitable for finished product inspection and single material index testing of industrial and mining enterprises. The electro-hydraulic servo universal material testing machine is suitable for testing laboratories of steel and building materials with higher requirements.
