High vacuum rotary friction and wear testing machine

The high vacuum rotary friction and wear testing machine is a professional testing equipment designed for the friction and wear performance of materials in high vacuum, low pressure and other environments. It is widely used in aerospace, semiconductor, new energy, vacuum equipment manufacturing and other fields. Compared with conventional friction testing equipment, it can accurately simulate the friction environment of special scenarios such as space and vacuum chambers. Through the rotating friction testing mode, it provides key data for the durability evaluation of materials and components used in the environment, and is a testing tool in the fields of manufacturing and scientific research.

From the perspective of device construction, the core consists ofHigh vacuum testing chamber、Rotating friction unit、Precision loading system、Vacuum control systemandData collection and analysis moduleComposition. The high vacuum testing chamber is made of stainless steel material and can achieve a high vacuum degree of 10 ⁻⁴ -10 ⁻⁷ Pa after sealing treatment, meeting the vacuum requirements of different scenarios; The rotating friction unit is equipped with a high-precision spindle, and the speed can be accurately adjusted within the range of 0.1-5000r/min. It is compatible with various friction pairs such as pin discs and ball discs, and is compatible with different material samples such as metal, ceramic, and composite materials; The loading system applies static or dynamic loads of 0.1-1000N through servo motors, with a loading accuracy of ± 0.01N, ensuring stable and controllable friction pressure; The vacuum control system is equipped with a molecular pump and a vacuum gauge, which can monitor and adjust the vacuum degree inside the chamber in real time to maintain a stable testing environment; The data acquisition module records real-time parameters such as friction coefficient, wear amount, vacuum degree, temperature, etc., with a data error of less than 3%, ensuring reliable detection results.

The core advantages of this device are focused on "environmental simulation accuracy" and "testing professionalism". The high vacuum chamber can realistically reproduce special scenarios such as space and the interior of vacuum equipment, avoiding interference from air and water vapor during the friction process, and the detection data is more in line with actual usage; The rotational friction mode is adapted to the working state of rotating components such as bearings, gears, and vacuum valves, with stronger specificity. In addition, the device supports linkage with other modules and can simulate composite environments such as low and high temperatures (-100 ℃ -800 ℃), further expanding the testing range.

In practical applications, equipment functions cover key areas: in the aerospace field, testing the wear resistance life of satellite bearings and rocket engine components in space vacuum environment; In the semiconductor industry, evaluate the friction loss of transmission components inside the vacuum chamber to ensure the stability of equipment operation; In the field of new energy, testing the wear resistance of rotating seals in lithium battery vacuum packaging equipment; In the field of vacuum equipment manufacturing, verify the friction reliability of core components such as vacuum pump rotors in high vacuum environments.
