introduction:The core problem of lubrication technology is to solve the friction pair——That is what we usually call the lubrication of the lubrication point,For those who are engaged in the application of lubrication technology,The main concern should be the lubrication point。That is to say,No matter what type of lubrication you use,Dry oil lubrication is good,Thin oil lubrication is good,Oil mist lubrication is good,Or use oil and gas lubrication,The purpose is to keep the lubrication point in the best lubrication condition at all times。 In that way,What kind of lubrication does the lubrication point need?The more oil you add, the better?The answer is no。 Lubrication point,That is, the friction pair in the full film lubrication state is an ideal operation
