3、 Instrument characteristics
1. This machine adopts a 7-inch color touch screen, and the human-machine interface provides users with detailed test information. It automatically records information such as the height of each impact, the weight of the impact hammer, and the impact speed. After the impact, the user inputs whether the sample is broken. The system automatically calculates the true failure rate TIR value (clockwise rotation method) or 50% failure height (ladder method) based on the input information. It operates in both Chinese and English, can speak, and has bilingual Chinese and English language, with voice prompts, making it more intelligent and meeting the needs of customers in different regions;
2. The electrical, mechanical, and software parts of this machine are equipped with safety protection measures, such as upper limit, lower limit, software limit, anti leakage, anti short circuit, anti static, anti interference, anti leakage, and anti misoperation functions;
3. The sample support plate of this machine adopts electric lifting, and the pipe sample can automatically align to the zero point, accurately positioning the zero point, saving time, effort, and convenient operation;
43. This machine has automatic zero point function for the hammer body, automatic gripping function after impact, and automatic lifting function. It is easy to operate, efficient, and intelligent during testing;
5. This machine adopts a pneumatic structure to achieve anti drop hammer secondary impact and release functions, with a success rate of 100% in preventing secondary impact capture. Abandoning the traditional concept of electromagnetic hammer connection and electromagnetic hammer release, adopting a pneumatic structure with greater force value that never burns out. The hammer connection function is a dual hammer connection structure, using a 300N long stroke cylinder, and the hammer connection surface is made of cow tendon plate material, ensuring stable and reliable hammer connection. The hammer is also equipped with a pneumatic structure, which has a non pneumatic automatic locking structure and is safe and reliable. Fundamentally solved the problems of long-term bending, breakage, leakage, and sliding of cables used in electromagnetic hammer release;
6. The hammer body of this machine has a fast lifting speed and adopts variable speed control, ensuring smooth and reliable system operation. The impact height can be arbitrarily set within the range of 2000mm, and height calibration is convenient and fast, avoiding errors caused by mechanical component accuracy. The calibration accuracy is within the range of ± 2mm;
7. The mechanical structure of this machine adopts a double screw four column support method, which is stable and has good rigidity. V-shaped iron is adjusted to accommodate pipes of different diameters and plate specimens with varying thicknesses. The combination impact hammer structure can be assembled with weights to meet the standard weight requirements.
