MMW-1A vertical universal friction and wear testing machine
Product name: MMW-1A microcomputer controlled vertical universal friction and abrasion testing machine
Product description
1. This machine has the friction forms of sliding, rolling or sliding-rolling compound motion under some contact pressures; it has a stepless speed regulating system, and under low speed or high speed conditions, it can evaluate the friction and wear properties of lubricants, metal, plastics, coating, rubber, ceramics and other materials, such as low-speed pin-on-disk (having large disk and small disk, single needle and three-needle) friction function, four-ball long-term antiwear property and four-ball rolling contact fatigue and thrust washer friction performance tests. It can replace American FALEX6 multi-functional testing machine, and it is a testing machine generally adopted by many units engaging in tribology researches, mainly used for tribology performance tests of materials and coating. The four-ball friction pair is used to test the antiwear property of lubricating oil, meeting the requirements of SH/T 0189-1992 “Method for Determining Antiwear Property of Lubricating Oil (Four-ball Machine Method)”, and it has been widely applied to the development of antiwear hydraulic oil products.
2. This machine is widely applied to various fields of technologies of tribology, petrochemical, machinery, energy, metallurgy, aerospace, various junior colleges and research institutes (institutions).
Standerde of use
The wear resistance of SH/T0189-92 lubricating oil determination (four ball method)
The wear resistance of SH/T0204-92 grease determination (four ball method)
Method for the determination of the friction coefficient of SH/T0762-2005 lubricating oil (four ball method)
