How much do you know about the factors and maintenance skills that need to be considered and maintained when purchasing electronic universal testing machines?

The electronic universal test machine is pollution-free, low noise, high efficiency, has a very wide speed regulation range and beam movement distance. In addition, it is equipped with a wide variety of test accessories. It has a very broad application prospect in the mechanical properties of metals, non-metals, composite materials and products. In terms of transmission control, there are currently two main forms, synchronization belts and reducers. The advantages and disadvantages are still to be discussed, but they do not affect users' use. Let me introduce to you the factors that need to be considered and maintenance skills when purchasing electronic universal testing machines.

1. Factors to consider when purchasing electronic universal testing machines

1. Software and hardware: High-quality electronic universal testing machines generally use brand computer control system software for Windows XP operating system platform, with the characteristics of fast operation speed, smooth interface, and simple operation, which can meet the experimental measurement needs of different data, and can measure physical functions of various types of data according to national standards, international standards or industry standards.

2. Ball screw: The current screws used in electronic universal testing machines include ball screws and trapezoidal screws. Generally speaking, the gap between trapezoidal screws is larger, the friction is larger, and the service life is short. There are some manufacturers in the market that use trapezoidal screws instead of ball screws in order to save costs and obtain greater profits. (According to the requirements of small and medium-sized customers, some trapezoidal screw products are mostly ball screws)

3. Motor: The high-quality electronic universal test machine The motor adopts an AC servo speed regulation system, Panasonic AC servo motor, and the function remains unchanged, and the transformer experiment has maintenance and installation such as overcurrent, overvoltage, and overload. There is also an electronic universal test machine on the market that uses a common three-phase motor or variable frequency motor. This motor uses imitation signal control, slow response, and accurate positioning. The normal speed regulation is narrow and there is no low speed. If there is a high speed, there will be no high speed. If there is a low speed, there will be no high speed. And the speed control is no high speed.

4. Sensor: The sensor is the main component of the accuracy and invariance of the test machine. The types of electronic universal test machine sensors on the market are S-type and wheeled. The accuracy of the internal resistance strain gauge of the sensor is not high, the anti-aging ability of the glue used to fix the strain gauge is not good, and the data of the sensor is not good, all affect the accuracy of the sensor.

5. Transmission system: There are two main types of transmissions in electronic universal testing machines: one is arc synchronous gear belt, and the other is common belt transmission. This transmission method has stable transmission, 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 transmission system.

2. Maintenance and maintenance skills of electronic universal testing machine

1. Wipe the surface of the electronic universal testing machine frequently to keep it clean.

2. Please wipe the electroplating part of the electronic universal testing machine with engine oil to prevent rust and keep the light bright.

3. Please add lubricant to the power screw and screw parts to ensure the transmission sensitivity.

4. Please arrange all fixtures and joint accessories and wipe the anti-rust oil to prevent rust.

5. Please wipe the control box of the electronic universal testing machine with a dry cloth to prevent water from being damaged to avoid damaging IC electronic parts.

The above are the factors and maintenance techniques that the editor has shared with you when purchasing electronic universal testing machines. I hope it can help you!
