First, product introduction:

The MVF-1H friction and wear test machine is a friction and wear tester with a variety of expansion platforms developed by Heng Xu's independent system. Under the set contact pressure, the machine can complete the friction form of a variety of friction pairs rolling, sliding or sliding on the point, line and surface. It has a stepless speed regulation system and can be at very low speed or high speed. Under conditions, it can be used to evaluate the friction and wear properties of lubricants, metals, plastics, coatings, rubber and ceramics. The friction pairs of typical pairs of friction pairs (with large plates and small plates, single needle and three needles), four ball long anti wear properties and four ball rolling contact fatigue, thrust washer, ball disc, etc. are used. Expansion tests such as ball bronze three lubricity, mud wear, sealing moment and stick slip friction performance of rubber seals.

The test machine is used in many fields of tribology, such as petrochemical, machinery, energy, metallurgy, aerospace, colleges and universities, research institutes and other departments. It has a wide range of applications and is a common friction and wear research equipment for teaching and scientific research.

Three. Brief introduction of friction pairs used in test machines

1、Pin disk friction test

The specimen for the pin and disk friction test is a circular ring for the specimen under the cylindrical pin. The material can be processed into a ring or a coating test on the ring, and the material can be processed into a pin sample. The single pin friction test can be carried out in a small test force, and the test can be carried out at the same time at the same time, and the friction pair pictures are as follows:

2、Friction test of thrust ring end face

Friction and wear tests can be carried out between the end faces of the materials. The friction samples of the studied materials can be processed to the upper and lower samples.

3、Ball disc friction test

The standard steel ball was used to test the friction resistance of the samples under friction and wear.

4、Four ball friction test

The four ball friction test is an effective way to evaluate the oil products. On the machine, the long ball grinding test can also be realized through the four ball friction pairs.

5、Lubricating oil wetting test

When the friction needs to be lubricated, the lubricating oil infiltration test can be carried out, and the oil can be heated at the same time. The wetting test is realized through the oil immersion pool.

6、Extension function

The test machine can also carry out a variety of tests such as SH0577, seal lip seal test, four ball contact fatigue test and stick slip and so on. Different fixtures can be made according to the requirements.
