As we all know, the hydraulic oil is an integral part of almost any hydraulic pump-powered hydraulic system necessary. Through to the fluid flow resistance (i.e. viscosity) accurate computations, proper viscosity of the hydraulic oil for hydraulic pump can provide the necessary protection to ensure that moving parts in an effective lubrication condition, to make them wear to a minimum.
However, to provide the necessary lubrication to protect only the most basic of hydraulic oil requirements; more important is how to make the hydraulic oil under high load conditions or changes in condition to perform its functions. For example, hydraulic equipment for outdoor operation, the temperature of their environment not only with seasonal differences great, even with alternating day and night operation the location change and change dramatically. At a high temperature, hydraulic oil becomes thinner, leading to insufficient lubrication, and wear increase; at low temperatures, the hydraulic system are difficult to start, start to wear and tear increases.
Inappropriate hydraulic oil is not only caused by wear and tear, but also lead to excessive corrosion and sludge deposits, cavitations, filter clogging and valve catching the problem. Equipment problems to solve, not only makes the noise increase, the work of the decline in accuracy will result in increased frequency of maintenance, downtime and other phenomena, and ultimately premature failure, greatly increase the efficiency of production equipment maintenance costs and reduce equipment .
Therefore, the choice of hydraulic oil, make hydraulic equipment than expected returns, although the importance of the hydraulic oil is often overlooked.
Impact crusher can crush each kind of coarse, medium, fine cubic material (granite, limestone and concrete etc) with feeding size not more than 500mm and crushing strength not more than 350MPa. Thus Impact Crusher is widely applied to secondary and tertiary crushing of various ores and medium-hard materials in railway, highway, energy, cement, chemical industry construction etc.
