Beit Manufacturing is a scientific research, production and service in one of the scientific and technological enterprises, specializing in micro-folding crawler crane production research. Here to introduce you to the next spider crane hydraulic oil common small problems, what is the cause?
    
    1, How is the bubble generated?
    
    Bubble Reason: When the filter or on-line clogging or air through the loose connector, the anti-foaming additive in the oil does not work, resulting in bubbles
    
    2, Why oxidation increases the viscosity of the oil?
    
    The viscosity of the oil used for a long time will not change, except for the exception of severe oil oxidation. General engineers through the experience that the oil after long-term use, sticky will be reduced, but it is generally in the machine 50-70 ℃ working state of the judge, and viscosity test is 40 ℃ case. In fact, with the degree of oil oxidation deepened, the viscosity will increase slightly!
    
    3, Why the temperature of the oil will rise?
    
    The main reasons are: oil is not enough or oil pollution. The amount of oil is not enough by the equipment design defects or oil leakage caused by oil pollution, especially oil oxidation of pollutants easily lead to the cooling system and filter blockage caused by oil temperature rise.

4, What is the relationship between oil leakage and pollution?
    
    When the oil temperature increases due to the above reasons, the viscosity of the oil will be reduced and the low viscosity oil will tend to exudate part of the connector. Keeping the low temperature and oil clean is a common way to avoid oil spills.
    
    5, The color of oil problems?
    
    Long-term use of oil due to the formation of color and color deepening, which is normal. Because the pigment dissolved in oil, and will not affect the quality of oil, so the oil alone to determine the color of oil is not correct or not.
    
    6, The role of oil in the water?
    
    There is water in the circulatory system to produce rust, rust can lead to valve and system problems, but also accelerate the oxidation of oil. And the oil and water separator can be used to remove the oil in the oil.
    
    7, The oil life
    
    Lubricants are affected by air, heat, impurities, and water. But the oil is completely purified and the change in oil below 60 ° C is very small and can be used for a long time. The consumption of the additive can be supplemented by a small amount of supplemental new oil.
    
    8, What is the deterioration of oil?
    
    Oil oxides continue to polymerize the oxide adsorption particles, resulting in "sandpaper-like" role is the bad consequences of oil deterioration. The deterioration of the oil causes the wear of the machine. In fact, the deterioration of the oil is essentially the oxidation of the oil!
    
    9, What size of the pollutants harmful to the hydraulic system?
    
    More than 1um particles on the hydraulic system will cause the filter to clog or pump failure. And 1um or so particles and the thickness of the oil film is similar, and oil oxidation pollutants together in the pipeline and valve parts in the gap wear pipe parts.
    
    10, Why measured acid value?
    
    The size of the acid value and oil oxidation is closely related to the situation is to check the degree of oil oxidation is an important indicator, generally if the acid value of the oil can be exceeded by removing the oil oxide method to reduce the acid value of oil.
