The future of mining machinery

Based on the actual characteristics of the situation in the mining machinery, oil is very strict on the requirements, as follows:
First: As the volume of mining machinery and its fuel tank volume are relatively small, so it is easy to appear the work of a high oil temperature, which requires oil to have better oxidation resistance and thermal stability.
Second: Because the gravel mining machinery working environment is very harsh, dust, water was relatively large, oil is vulnerable to the contamination of impurities in the external environment, so the oil must have a good anti-rust and anti- corrosive. Only in this way by the outside world when the oil in the case of adverse environmental impact, its performance will not have significant change.
Third: the working environment of mining machinery and equipment is usually outdoors, so the work environment affected by temperature changes, especially the large temperature difference between summer and winter, day and night temperature difference in some areas is relatively large, so the oil viscosity must be less affected by temperature, this area requires high temperature, it will not lead to too low viscosity, but not the line as a lubricant, the other is to avoid the temperature is low, a result of low oil viscosity Start with the operation difficult.
Fourth: There are some easy fire or explosion mining machinery, of course, requires a certain degree of anti-flammable oil, mineral oil can not be used to fuel for lubrication. Fifth: The last is certainly better than the seal lubricant to prevent seal damage and impact on the effect of lubricating oil. Lead to some unnecessary risk.
