First, from the use of performance:
Electronic universal testing machine, no oil source. Therefore, it is cleaner, easier to use and maintain, and its test speed range can be adjusted. The test speed can reach 0.001mm/min-1000mm/min, and the speed ratio can reach as much as 1 million times. The test stroke can be determined as required. flexible. The precision of force measurement is high, and some can even reach 0.2%. It is small in size, light in weight and large in space. It is convenient to add corresponding devices to do the mechanical tests of various materials. Really a multi-purpose machine. At present, the electronic universal testing machines produced by the mainstream testing machine manufacturers in China can all achieve so-called three-closed-loop control of load control, strain control, and displacement control.
Hydraulic universal testing machine, limited by the flow of oil, his test speed is low. Manual hydraulic universal testing machine is easy to operate and cheap, but it has low control accuracy. Electro-hydraulic servo universal testing machine, compared with the electronic universal testing machine, in addition to low speed, the control accuracy is not bad, the use of load cell microcomputer control electro-hydraulic servo universal testing machine, force value accuracy can reach about 0.5% . And when making large-tonnage mechanical tests, it is more reliable, more stable, and more cost-effective.
Second, from the scope of application:
Electronic universal testing machine, widely used in various metals, non-metal, composite materials, medicine, food, wood, copper, aluminum, plastic profiles, wire and cable, paper, film, rubber, textile, aerospace and other industries to pull Extensive performance test, at the same time according to user-supplied domestic and international standards for a variety of test data processing software and test aids. The digital display electronic universal testing machine is suitable for users who only need relevant data such as force value tensile strength compressive strength. If you need to take more complex parameters, microcomputer control electronic universal testing machine is your better choice. In terms of cost performance, electronic universal testing machines below 30T have advantages.
Hydraulic universal testing machine is mainly used for tensile, compression, bending and other mechanical properties of metal, non-metallic materials and parts, components and components. Hydraulic universal testing machine is an ideal test equipment for industrial and mining enterprises, building materials, quality inspection centers, water conservancy and hydropower, bridge engineering, scientific research institutes, colleges and universities mechanical laboratory. Manually controlled hydraulic universal testing machine is cheap and suitable for the inspection of finished products of industrial and mining enterprises and single material index testing. The electro-hydraulic servo universal material testing machine is suitable for high-demand steel and building materials testing laboratories. More than 30T electro-hydraulic servo universal material testing machine is more expensive than electronic universal testing machine.
Third, from the structural characteristics:
The electronic universal testing machine mainly uses the servo motor as the power source, and the screw and the nut as the executing parts to realize the speed control of the moving beam of the testing machine. In transmission control, there are currently two main forms, timing belts and speed reducers. Domestically, the testing machine manufacturers in Changchun use synchronous belts, and the testing machine manufacturers that come out of Hongshan use reducers. Regarding its advantages and disadvantages, it remains to be explored, but it will not affect users' use. Electronic load testing machines use load sensors for force measurement.
Hydraulic universal testing machine, as its name implies, uses a high pressure hydraulic source as a power source. Use manual, servo or proportional valves as control elements for control. Ordinary hydraulic universal testing machine can only be manually loaded to achieve manual, is an open-loop control system, subject to price factors, load cells generally use hydraulic pressure sensors. The electro-hydraulic servo universal material testing machine uses servo valves or proportional valves as control elements for control. Some domestic manufacturers have also adopted high-precision load sensors for force measurement.

A needle nozzle nose tube is a small, thin tube with a pointed end that is used for a variety of medical procedures. It is typically made of plastic or metal and is used to inject or extract fluids or gases from the body. The needle nozzle nose tube is commonly used in procedures such as blood transfusions, intravenous therapy, and anesthesia administration. It is also used in diagnostic procedures such as biopsies and aspirates. The needle nozzle nose tube is designed to be precise and minimally invasive, allowing for accurate delivery of medication or fluid without causing significant discomfort or damage to surrounding tissue.
