1.The viscosity of hydraulic oil is generally relatively small, and the viscosity of lubricating oil is generally relatively large, so when hydraulic oil is used as lubricating oil, the production of oil slicks is more difficult, and this is very easy to cause the equipment to wear out more, and even have serious adverse effects。

    2.The difference between hydraulic oil and lubricating oil is that the key effect is not the same, therefore, the preservatives inside them are not the same, and the two kinds of oil can cause a change in characteristics, and even produce chemical changes to promote oil mildew, resulting in equipment wear。

    3.The operating temperature of the hydraulic transmission system is not high, but the working pressure of the hydraulic oil transmission enterprise is very large。As everyone knows, the operating temperature of the crankcase ventilation of the diesel engine is very high, coupled with the high-pressure natural gas penetration of the engine combustion chamber, which will promote the various functions of the hydraulic oil to be faster and ineffective, resulting in an increase in equipment wear, and the situation will cause higher damage。
