Density detection for the treatment of oil filter equipment for waste liquid pressure oil
2018/5/15 Viewers:
The main quality requirements of hydraulic oil. 1. suitable viscosity and good viscosity temperature performance, in order to ensure that the working temperature change conditions can accurately and sensitively transfer power, and can ensure the normal lubrication of hydraulic components. 2., it has good rust resistance and antioxidant stability. It is not easy to oxidize and deteriorate under high temperature and high pressure condition, and has long service life. 3. has good foam resistance, so that the oil in the working conditions of continuous mechanical agitation, the foam will easily disappear to make the power transfer stability, to avoid the accelerated oxidation of hydraulic oil. The density test of the hydraulic oil after the oil filter, (1) the densimeter must be cleaned completely before use, and after the wiping, do not hold all the parts below the maximum dividing line so as not to affect the reading. (2) the diameter of the measuring cylinder for measuring the density of the test oil should be twice larger than the diameter of the body by the densitometer, so as to prevent the density meter from colliding with the inner wall and influence the accuracy, and its height should be appropriate. (3) when the density meter is immersed in the oil test, do not use the hand to push down the densitometer. It should be gently placed to prevent the density gauge from sinking at the bottom of the measuring cylinder and breaking the densitometer. (4) the position of the readings, regardless of the determination of the transparent or dark oil, should be read on the upper edge of the liquid surface, and the eye and the upper edge of the liquid must be at the same level when reading. (5) do not take the end of the density gauge sideways to prevent breaking. (6) if the density scale displacement of the densitometer is found and the glass has cracks, it should be stopped. (7) the bubbles will be affected when bubbles are inside or on the surface of the sample, and bubbles should be removed before testing. (8) when measuring the density of mixed oil, it must be stirred evenly. (9) while reading, the temperature of the specimen should be recorded.
