Fat discriminant smooth transformation method

Bearing in the process of operation, in order to provide better performance, general will stop smooth bearing, using smooth fat can reduce bearing friction degree and the rise of temperature, smooth fat is a metamorphosis, if not less than the relevant role, instead of bearing the use of more and more bad, so when we purchase smooth fat must learn how to distinguish between smooth lipid can ever change. Discriminant smooth fatty metamorphosis way: 1, the oil flow to examine method take two cups, one containing smooth oil need to be checked out, the other one empty on the desktop, separate the cups with smooth oil for high 30 - desktop 40 cm and tilt, make smooth oil flow gradually to the empty cup, to examine its activity, good quality and smooth oil when the oil flow should be a slender, on average, from time to time, a series of if present oil flow fast and slow, and sometimes has a large flow, says smooth oil has turned. 2, hand twist will smooth oil lay between his thumb and his finger repeat grinding, good smoothness smooth oil hand feel, less abrasive dust, no friction, if feel fingers between the larger friction feeling such as sand, smooth oil indicates the impurity is much, can't use, should change new smooth oil. 3, illumination method in a clear day, lifted with screwdriver will smooth oil, and the degree of surface into a 45 degree Angle. Contrast sunshine, check the oil situation, under the light, can be clearly seen smooth oil without chip is good, can continue to function, if excessive wear debris, smooth oil should be changed. 4, oil droplets trace method take a clean white paper, number of oil drops on the filter paper, after being smooth oil leakage, if there is black powder appearance, touch resistance acerbity feeling, the clear smooth oil inside has a lot of impurity, good smooth oil powder, with the hand feels dry and lubrication, and yellow.
