Today i will talk about the advantages and disadvantages of grease.Lubricating grease has the following advantages. The first point:Long service life.Semi-solid state reduces grease consumption and reduces maintenance cost. The second point:Lubrication equipment is simple.Certain structural strength,not easy to lose and splash in the lubrication site.The third point:It has adhesion. Good retention force to protect the lubrication parts from rust. The fourth point:It has its own seal. It can effectively prevent the intrusion of dust and moisture.The fifth point:Buffer shock absorption effect.It can effectively reduce the noise and vibration.The last point:Good load resistance.It can be used long under high temperature,low speed and heavy load conditions.Next are the disadvantages of grease.The first one:Poor liquidity.The semi-solid state makes the grease almost unfluid. The second one:Poor heat dissipation effect.It is not easy to take away the heat generated by the lubrication parts at work. The third one:The starting moment is large.Low temperature initiation leads in increased torque. The forth one:High-speed equipment is not applicable.DN less than300,000 mm.r/min.The fifth one:Automatic lubrication is very difficult.The pumping capacity of the grease is relatively poor.The last one:Replacement difficulties. Viscous grease replacement is complex,and it is difficult to remove surface impurities.Thank you for watching,see you next time.
