Selection method of hydraulic element hose used in hydraulic system

Most of the high-pressure hoses used in the hydraulic system in the industry are made of synthetic rubber and are reinforced by the intended load. The utility model is characterized in that the inner pipe is made of oil resistant synthetic rubber, and a plurality of reinforcing layers are arranged outside the inner pipe. The reinforcing layer can be a prepared and residual active both. The outermost layer is a layer of oil resistant skin. Each layer of adhesive. In the hose impact test, the impact pressure is about 100%-133% of the rated pressure in order to consider the influence of transient pressure. The pressure test pressure is 50% of the burst pressure, the working pressure is not more than the lowest holding pressure of 25%. For industrial purposes, this acceptable safety requirement, and it also makes the hose withstand some impact pressure. Because almost all of the hydraulic system impact pressure, the pressure relief valve may exceed the set value and influence element hose and system in the life, so in the system of serious impact, should choose can improve the hose safety system. On the other hand, in the system with little or no impact, the smaller safety factor can be used.
