In the winter, low oil grade lubricants are used. The oil quality is relatively thin. Under low temperature conditions, the fluidity can be guaranteed. If high oil grade lubricants are used, the oil quality is thick and the fluidity is not good. If there is no heating and oil in the room. With the preheating device, the pump station will not work at all.
In the summer, you need a lubricant with a higher oil number and a relatively thicker oil. Because the weather is hot, the indoor temperature is also high, so that the thicker oil becomes thinner, as long as the fluidity of the oil can be ensured. If the oil number is lower in summer, the lubrication effect may not be ideal, and there will be a phenomenon that the oil will flow away quickly without forming an oil film on the lubrication point. First, it is wasteful and easy to produce heating phenomenon in various lubrication parts. Second, it does not meet the oil leakage phenomenon that is prone to oil production in civilized production.
Therefore winter and select the second quarter when oil number of different lubricating oil, mineral processing plant in the selection and use of lubricating oil to be determined according to the number of regional climate conditions and actual production experience.
