Construction machinery hydraulic hose assemblies used

Department of Construction machinery hydraulic hose assembly hydraulic system of hydraulic components mainly due to improper selection and use of frequent failure, or even result in long-term shutdown the host . Feedback information from the user , and often reflect these problems . To this end , construction machinery hydraulic hose assembly between the selection and use of questions drawn increasing OEMs , supporting plant and the user 's attention. A hydraulic hose assembly composition and type of a  Hydraulic hose fittings hose assembly hydraulic hose assembly consists of the composition of hydraulic hose ( or resin hose ) and metal fittings components. Hydraulic hose from the outer layer , reinforcing layer and the inner layer composition. The inner layer in contact directly with the hydraulic pump , generally small wax rubber , the long-term corrosion from the fluid state , to leak-proof, the enhancement layer is the skeleton of the hydraulic hose , mainly from the effect of pressure , the outer layer adhered to the enhancement layer protective effect on the general use of polybutadiene rubber grip and prevent the aging cracking. Metal fittings from the joint core , nuts and coat composition. (2) according to the type of hydraulic hose assembly hydraulic hose with metal fittings are connected not wait , can be divided into removable and withholding , withholding type can be divided into Straight and elbow -type , according to the form of enhancement layer different
