Analysis of characteristics of miniature cylinder

Miniature cylinder with different standard cylinder work, miniature cylinder under the normal work, the work surface with piston ring form mutual movement of uneven wear. The main characteristics and the reasons of the wear and tear has the following several aspects. From the micro cylinder profile, micro cylinder wear form 'on the big small', after losing the original is the shape of a cylinder, referred to as the 'cone'. The reasons of the 'cone' wear and tear, such as wear and tear of lubrication conditions change. Miniature cylinder wall by splash lubrication, so easily lead to upper miniature cylinder oil is difficult, and the upper temperature is high, the lubricating oil viscosity dilution serious, easy to loss, not easy to form oil film, even if there is the oil film, may also be burned. In addition, the mixture of tiny droplets of miniature cylinder upper oil film flushing damage superposition of a variety of factors such as oil scraper ring, cause poor lubrication of miniature cylinder upper, piston ring and the micro cylinder wall is easy to form dry friction or boundary lubrication condition, the upper bound to lead to the micro cylinder wear. Look from miniature cylinder profile, in the central of miniature cylinder wear the biggest parts, commonly known as 'drum-shaped'. Caused by a tiny cylinder 'drum-shaped' of the main causes of the wear, abrasive wear. The dust in the air, the impurity in the lubricating oil, clamping between piston ring and miniature cylinder wall, formation of harmful abrasives when the piston moves up and down. Because the fastest in the middle of miniature cylinder piston movement, so the abrasive effect on grinding process of miniature cylinder wall in the central of miniature cylinder is the most serious, making of miniature cylinder forming 'drum-shaped' wear and tear. As a result of the piston in micro motion when the lateral pressure in the cylinder are role in left and right of miniature cylinder. As a result, 'drum-shaped' wear the biggest parts usually left and right in the middle of miniature cylinder.
