Jaw crusher as the most widely used devices on the market,Great Wall Heavy Industry pay more attention to the lubrication in the process of use and maintenance , choose suitable lubricant to reduce the occurrence of failure and improve the operation rate of equipment.So when do maintenance,what are requirements for jaw crusher lubricant? Here we will introduce from the four aspects:
1, strong stability: the volume of a jaw crusher and tank volume are small, the amount of lubricant is also less loaded, when in the working process,the oil temperature is high, which requires lubricants have better thermal stability and oxidation resistance.
2, with protective performance: because of the bad jaw crusher work conditions, coal dust, ash, moisture content is more, lubricant is easily polluted by these impurities, so lubricants are required to have good rust and corrosion resistance, resistance to emulsifying performance, when the lubricant is contaminated, its performance will not be much change, which are less sensitive to pollution.
3, little affected by temperature: jaw crusher outdoor work, summer and winter temperature change is very big, in some areas is also a great temperature difference between day and night, thus requiring a lubricant viscosity variation with temperature is smaller, both to avoid the temperature is high, oil product viscosity becomes too low, the lubricating film can not be formed, would not achieve lubrication and to avoid the low temperature, the viscosity is too high, resulting in the starting, running difficulties.
4, good burning resistance: jaw crusher is often used in the mine which easily occur fire and explosion accident ,requires the use of a good anti-flammable lubricant (fire resistant liquid), you can not use flammable mineral oil.
