Smooth oil bearing the five functions and the dangers of inferior smooth oil

Bearing oil is a precision machine tool spindle bearing special smooth oil and similar equipment, it is to ensure the accuracy of the spindle to work and to use performance, prolong the using life plays a very important role. So the selection of the smooth oil is extremely important. （ A) 。 Smooth oil five functions: a. Smooth: provide friction surface smooth oil separation membrane, cold start wear accounted for 70% of launch machine overall wear and tear. b。 Cleaning: pollutants to clean down the smooth parts from INA bearing, and dispersed into very small particles. c。 Cooling: reduce because of the heat generated by the friction, to take away heat through the circulation and cooling. d。 Anti-corrosion: air and water to avoid corrosion of components. e. Seal: avoid channeling gas. Good smooth oil has the above five big function, but if use quality is bad way to smooth oil or use undeserved, can bring some to launch machine problem. （ 2) 。 The harm of inferior smooth oil a. The burning bush: if choose smooth oil quality is bad, the smooth oil viscosity is wrong, or choose smooth effect is bad. The oil pressure is too low, a machine oil, cooling system problems and deficiency can get overheated by machine. High-speed operation under this situation, is easy to INA bearing damage, commonly known as the 'burn'. In addition, if the use of inferior oil filter or not on time to change the oil filter, caught in the meantime, will cause the impurities form 'burn'. b。 Snap ring: if smooth oil cleaning dispersity is bad, after long-term use will produce carbon deposit around the piston ring, piston ring and carbon deposit serious when can form stuck or broken. c。 Oil cost is too big: if smooth oil wear resistance is bad, will lead to abrasion between piston ring and cylinder, oil scraper ring effect weakened, quench oil into the room to participate in, produce exhaust pipe at blue smoke phenomenon. If a machine's bad seal, valve oil baffle ring failure also can form such as oil leakage, also can accelerate the cost of oil. d。 Machine oil lamp alarm: once the attack this kind of phenomenon mainly find reason in the following aspects: lack of smooth oil ( Add) ； The oil induction plug damage ( Change) ； Oil pump filter infarction ( Cleaning) ； Lack of smooth oil viscosity ( Smooth oil change or check any overheating fuel dilution and launch machine) ； The oil pressure limiting valve spring failure ( Clean change) 。
