Therefore, under the condition of heavy load, metal elements transfer and surface element segregation will occur in the process of metal to metal friction(brown aluminum oxide). Under the condition of hydrodynamic lubrication or elastohydrodynamic lubrication, if the viscosity or speed of lubricating oil decreases, or the load increases, the lubricating oil film will become thinner(brown fused alumina for grinding). The pressure distribution of oil film can be easily obtained by using this formula.

When the contact of micro convex body occurs, the lubrication state will enter the zone, that is, partial elasticity Hydrodynamic lubrication or mixed lubrication area(brown fused alumina). The smaller the value of V · FX, the more prominent the effect of the former. Therefore, Stribeck curve shows an obvious upward trend in this region. The lubricant is Newtonian fluid, that is, the shear stress is proportional to the shear rate(brown aluminum oxide blast media). For example, oil pump is often used to supply oil to the air gap.

(bulk buy cheap brown aluminum oxide 24 grit belgium)When the working conditions move further to the left of the curve(white fused alumina price), the number of contact between the convex bodies will further increase, and the oil film thickness will be reduced to a few molecular layers or even thinner, and then the curve will enter the region, i.e. the boundary lubrication area(brown aluminium oxide manufacturer). The basic equation of hydrodynamic lubrication theory is the differential equation of pressure distribution in lubrication eyes.

Reynolds equation, which was derived in 1886 by Reynolds according to the basic equations of viscous fluid mechanics, made some simplified assumptions(brown aluminium oxide). Therefore, hydrostatic lubrication bearings are also widely used, ranging from small precision machinery to heavy machinery, such as radio and optical telescopes, machine tools, rolling mills(aluminium oxide grit 24 mesh), radar antennas and various low-speed and heavy-duty equipment, and achieved remarkable results.

The fluid movement in the film is laminar flow, not plain flow(white aluminum oxide blast media). The fluid does not slide on the boundary, that is, the velocity of the reservoir near the working surface is the same as that of the working surface. Along the oil film thickness direction, the oil pressure is constant, because the oil film is very thin, the oil pressure can not change significantly(white aluminum oxide 120 grit), and the viscosity along the oil film thickness direction is also unchanged.(bulk buy cheap brown aluminum oxide 24 grit belgium)

Different from hydrodynamic lubrication, hydrostatic lubrication relies on the external fluid pressure to support the load(white fused alumina manufacturer). In this way, a set of complex oil pump and oil circuit system will be added to the equipment, and the equipment cost will be correspondingly increased(white fused aluminum oxide 60 grit). However, hydrostatic lubrication has many advantages, such as: the friction force tends to zero in theory, because the weight is suspended on the oil film, it can be operated with a small force.

(bulk buy cheap brown aluminum oxide 24 grit belgium)Soviet scholars first developed the theory and practice of so-called "selective transfer" by using the principle that metal transfer can change the friction and wear characteristics(brown fused aluminum oxide suppliers). In this state, the load will be partly borne by the convex body and partly by the oil film. The friction resistance also comes from the interaction of the asperities and the shear of the oil film(black aluminium oxide). There is no direct contact between the surfaces of the parts, so wear does not occur.
