5 Factors that Influence the Pros and Disadvantages of Electronic Universal Testing Machines [Information]

Electronic universal testing machines are equipment that researchers often use. When purchasing experimental instruments, you must choose a high-quality one, otherwise it will affect subsequent scientific research data. How should we identify the advantages and disadvantages of the electronic universal testing machine? First, you can observe the appearance material of the electronic universal testing machine, and then find some materials to try its tensile and compression effects. Below, let’s introduce 5 factors that affect the advantages and disadvantages of electronic universal testing machines.

The ball screw, sensor, motor, software, hardware and transmission system of the electronic universal test machine are important components of the test machine. These five factors play a decisive role in how to choose a high-quality test machine.

1. Ball screw: The current screws used in electronic universal testing machines include ball screws and trapezoidal screws. Generally speaking, the gap between trapezoidal lead screws is relatively large, the friction force is relatively large, and the service life is short. There are currently some manufacturers on the market who use trapezoidal screws instead of ball screws in order to save costs and obtain greater profits.

2. Electronic universal testing machine sensor: Sensors are important components of the accuracy and strength stability of the test machine. Currently, the types of electronic universal testing machine sensors on the market include S-type and spoke type. The internal resistance strain gauge of the sensor is not very accurate, the glue used to fix the strain gauge, poor anti-aging ability, and poor sensor materials will all affect the accuracy of the sensor.

3. Testing machine motor: The high-quality electronic universal tester motor adopts an AC servo speed regulation system, Panasonic AC servo motor has stable and reliable performance, and has protection devices such as overcurrent, overvoltage, and overload. There is also an electronic universal test machine on the market that uses ordinary three-phase motors or variable frequency motors. This motor uses analog signal control, slow control reaction and inaccurate positioning. Generally, if the speed regulation range is narrow, there will be no low speed or if there will be low speed, there will be no high speed, and the speed control will be inaccurate.

4. Electronic universal testing machine software and hardware: The high-quality electronic universal testing machine adopts brand computers and control system software as an operating system platform. It has the characteristics of fast running speed, mild interface and simple operation. It can meet the test and measurement needs of different materials. It can measure the physical performance test of various materials according to national standards, international standards or industry standards.

5. Transmission system: There are two main types of transmission parts of the electronic universal test machine: one is the arc synchronous gear belt and the precision lead screw secondary transmission; the other is the ordinary belt transmission. The first transmission method is smooth, has low noise, high transmission efficiency, high accuracy and long service life. The second transmission method cannot guarantee the synchronization of the transmission, so the accuracy and stability are not as good as the first transmission system.
