Product Features:
1. The complete machine boasts an aesthetically pleasing appearance, a compact structure, and the main part with an arched design adheres to ergonomic requirements.
2. The entire machine is coated with gray-blue metallic paint, distinguishing the testing and operation sections from the control section. The metallic paint is wear and corrosion-resistant, offering excellent protection during wet friction tests.
3. The loading motor is equipped with an imported AC servo motor, ensuring balanced loading with minimal noise.
4. The machine is controlled by a computer, achieving automatic control of test conditions, data collection, and curve plotting.
5. The electrical measurement and control section has been upgraded with new integrated circuits, offering high accuracy, reliability, and ease of maintenance.
Product Details:
1. This machine exhibits frictional forms with sliding, rolling, or a combination of sliding and rolling motions under certain contact pressures. It is equipped with a variable speed system that allows for evaluation of the friction and wear properties of materials such as lubricants, metals, plastics, coatings, rubbers, ceramics, etc., at both low and high speeds. Examples include tests for frictional functions of low-speed pin disks (with large and small disks, single and triple needles), long-term wear resistance of the four-ball test, rolling contact fatigue, and thrust ring friction performance. It can replace the American FALEX 6 multi-functional testing machine, which is widely used by many friction research units for testing tribological properties of materials or coatings. The four-ball friction tester is used to determine the wear resistance of lubricating oils, meeting the requirements of SH/T 0189-1992 "Method for Determining the Wear Resistance of Lubricating Oils (Four-Ball Method)". This method has been widely applied in the development of anti-wear hydraulic oil products.
2. This machine has broad application prospects in various technical fields of tribology, petrochemicals, machinery, energy, metallurgy, aerospace, as well as in universities, colleges, and research institutes (institutes).
