First, product introduction:

MVF-2A friction and wear tester is a frictional form with rolling, sliding or sliding rolling under certain contact pressure. It has a stepless speed regulation system and can be used to evaluate the friction and wear properties of lubricants, metals, plastics, coatings, rubber, ceramics and other materials, such as low speed pins, at very low speed or high speed. Disk (with a large plate and small plate, single needle and three needles) friction function, four ball long anti wear performance and four ball rolling contact fatigue, ball to bronze three lubrication performance, as well as thrust washer, ball to disc, mud wear, rubber seal ring seal moment and stick slip friction performance test, matching reciprocating module can be reciprocated Friction and wear movement. The test machine has a wide application in the field of tribology, petrochemical, mechanical, energy, metallurgy, aerospace, colleges and universities, research institutes and other departments.

Three. A summary of the friction pairs of the test machine

1, frictional test of pin and plate

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:

Friction test on end face of 2 and thrust ring

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, friction test of ball plate

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.
