When choosing lubricating oil for a crusher, We need to consider the following factors:
Working environment and season of the machine
In high temperature environment, high viscosity lubricating oil should be selected. Because high-viscosity lubricating oil can provide better oil film strength. It can prevent lubricating oil from evaporating and oxidizing, and can better absorb and disperse the heat generated by machine operation.
In low temperature environment, low viscosity lubricating oil should be selected. Because the lubricating oil with low viscosity can be pumped and circulated, reducing friction loss. It can improve the fluidity of the lubricating oil. Then so that it can penetrate into all parts of the machine better.
Working pressure and speed of the machine
When the working pressure is high and the speed is fast, we should select lubricating oil with high viscosity and good anti-wear performance. Because high-viscosity lubricating oil can provide better oil film strength, resist friction and wear under high pressure and high speed, and can better absorb and disperse vibration and impact generated by machine operation.
In the case of low pressure and low speed, lubricating oil with lower viscosity can be selected to reduce friction loss and energy consumption.
Material of friction surface
If the friction surface is metal, we can select lubricating oil with low metal friction coefficient. Because the coefficient of friction between the metal is bigger. If we choose low coefficient of friction lubricating oil, then can reduce the friction and wear and the energy consumption of the machine.
If the friction surface is non-metallic, lubricating oil suitable for non-metallic materials should be selected. Because smaller friction coefficient of non-metallic materials, choice of non-metallic materials suitable for lubricating oil can better protect the friction surface, reduce wear and prolong service life.
In addition, it is necessary to consider the properties of the lubricating oil such as oxidation resistance, corrosion resistance and emulsification resistance, as well as the brand and quality assurance of the lubricating oil. When selecting the lubricating oil of crusher, it is necessary to consider comprehensively according to the specific needs and conditions to select the most suitable lubricating oil. If you need more detailed information or advice, consulting professionals or manufacturer’s technical personnel.
