Hydraulic oil is an important medium, but the normal operation of the hydraulic machine, hydraulic oil liquid in use after a period of time, because the effect of high temperature oxidation, impurities and other factors, the quality will decline, the function will decline, that is to say in the oil to a certain extent, we demand the timing of replacement. Then, when should we replace the hydraulic fluid? How can we tell if the hydraulic oil solution should be replaced? Don't worry, let me tell you about it.
  Hydraulic hydraulic oil pump, oil and tank oil two, for the two kinds of different methods of identification:
  1, pump oil identification: we can take a small amount of detected oil from the pump, the viewer color change, if it is found that it has a milky white opaque shape (sometimes like pale yellow milk), perhaps by burning method to identify, find which contains a lot of water, burning will emit a lot of white smoke, hand touch and feel lost this stickiness, some phenomena which the oil emulsion has been completely transformed, and it should not be replaced, demand.
  2, tank oil identification: take out a small amount of oil to be measured from the tank, gum deposition, put it on your fingers, twist, pinch, and if you feel the gum more, adhesion is strong, it is clarified that the oil has been oxidized. Perhaps after filtration with filter paper, if filter paper retained the black residue, and with a red nose smell, is the oil oxidation has been transformed, of course, can also be directly removed from the tank at the bottom part of sludge deposition, if you find that there are many asphalt and transformation, this shows the above phenomenon of oil tank has been oxidized transformation function is now serious decline, demand for replacement.
  After the introduction, we know that the oil pump and oil tank multi identification method is very simple, only on the basis of the above through the eye view may touch, even burning way, you can easily determine whether the oil change, whether demand substitution.
