The electronic universal testing machine is a testing equipment frequently used by various industries such as wire and cable, building materials, petrochemicals, textile materials, rubber and plastics, and quality supervision departments, scientific research institutions, etc. The factors that affect the quality of electronic universal testing machines are mainly There are five points:
First, the motor quality electronic universal testing machine motor using AC servo speed control system, Panasonic AC servo motor, stable and reliable performance, with over-current, over-voltage, overload protection devices. At present, there is still an electronic universal testing machine using ordinary three-phase motor or variable frequency motor, which uses analog signal control, slow control response, positioning is not accurate, the general speed range is narrow and there is no high speed, there is no low speed or low speed No speed, and speed control is inaccurate.
2. The sensor sensor is an important component of the precision and force measurement stability of the electronic universal testing machine. Currently, there are S type and wheel type electronic universal testing machine sensors on the market. Sensor internal strain gauges are not high accuracy, fixed strain gauges with plastic aging resistance is not good, the sensor's material will affect the sensor's accuracy.
Third, the ball screw electronic universal testing machine currently used ball screw and trapezoidal screw. In general, trapezoidal screw gap is relatively large, the friction force is relatively large, and the service life is short. At present, there will be some manufacturers on the market. In order to save more costs, they will use a lead screw instead of a ball screw.
Fourth, the transmission system electronic universal testing machine There are two kinds of transmission parts, one is the arc synchronous gear belt, precision screw vice drive; the second is the ordinary belt drive. The first transmission method has stable transmission, low noise, high transmission efficiency, high precision, and long service life. The second transmission method cannot guarantee the synchronism of the transmission. Therefore, the accuracy and stability are not as good as those of the first transmission system.
V. Software and Hardware The high-quality electronic universal testing machine adopts the brand computer, and the control system software is the Windows XP operating system platform. It has the features of fast running speed, mild interface, and simple operation. It can meet the needs of different materials for testing and measurement, according to national standards. International standards or industry standards measure physical properties of various materials.
