The difference between electronic universal testing machine and hydraulic universal testing machine

  Electronic universal testing machine and hydraulic universal testing machine are all material mechanics testing instruments, but have their own characteristics in terms of structural characteristics, performance, application range, etc. Users can decide whether to use electronic universal testing machine or hydraulic according to the specific use environment of the industry. Universal testing machine. Zhongshi Testing Equipment Co., Ltd. summed up the difference between the electronic universal testing machine and the hydraulic universal testing machine. Let's take a look!

Structural features

Electronic universal testing machine

  The servo motor is used as the power source, and the screw and the nut are used as the execution components to realize the speed control of the moving beam of the testing machine.

There are two types of sensors:

  1, timing belt

  2, reducer

  The electronic universal testing machine uses load sensors.

Hydraulic universal testing machine

  1. The high-pressure hydraulic source is used as the power source, and the manual valve, servo valve or proportional valve is used as the control element for control.

  2. Electro-hydraulic servo type universal material testing machine adopts servo valve or proportional valve as control element for control. Some domestic manufacturers have also adopted high-precision load sensor for measuring force.

Microcomputer control electronic universal testing machine

 Performance

  Electronic universal testing machine

  1. Electronic universal testing machine, no oil source, more clean, more convenient to use and maintain;

  2, the test speed range can be adjusted, the test stroke can be determined according to needs, more flexible;

  3, the measurement accuracy is high, and some can even reach 0.2%;

  4, small size, light weight, large space, easy to add the corresponding device to do the mechanical test of various materials, truly a multi-purpose machine.

  5. The electronic universal testing machine produced by the domestic mainstream testing machine manufacturers can achieve the so-called three closed-loop control of load control, strain control and displacement control.

Hydraulic universal testing machine

  1. Limited by the flow rate of the oil source, the test speed is low.

  2, manual hydraulic universal testing machine, the operation is relatively simple, the price is cheap, but the control accuracy is low;

  3. Compared with the electronic universal testing machine, the performance of the electro-hydraulic servo universal testing machine is not inferior except for the low speed; the microcomputer-controlled electro-hydraulic servo universal testing machine using the load sensor;

  4, the force value accuracy can also reach about 0.5%, and in the large-tonnage material mechanics test, more reliable, more stable, more cost-effective.

Electronic universal testing machine

  1. It is widely used in the testing of tensile properties of various metals, non-metals, composite materials, wood, plastic profiles, wire and cable, paper, film, rubber, medicine, food packaging materials, fabrics, etc.

  2. Various test data processing software and test aids can be customized according to domestic and international standards provided by users;

  3. The digital display electronic universal testing machine is suitable for users who only ask for relevant data such as force value, tensile strength and compressive strength. If the demand takes more complicated parameters, the microcomputer control electronic universal testing machine is a better choice for you;

Hydraulic universal testing machine

  1. It is mainly used for testing mechanical properties such as tensile, compression and bending of metal and non-metal materials and parts, components and components.

  2. Manually controlled hydraulic universal testing machine, which is cheap and suitable for finished product inspection and single material index testing of industrial and mining enterprises;

  3, electro-hydraulic servo universal material testing machine, suitable for high-demand steel, building materials testing laboratory.

  4, 30T or more electro-hydraulic servo universal testing machine and electronic universal testing machine, it has a price advantage.
