Analysis of hydraulic hose connector assembly structure and sealing performance

Analysis of hydraulic hose connector assembly structure and sealing performance in the hydraulic system of hydraulic hose assemblies to connect and play the role of conveying hydraulic oil , hydraulic system known as " blood ." However, since the structure of the hydraulic hose assembly and manufacturing is relatively simple , it is not been adequate attention , are often unreasonable or processing and assembling structural design of mistakes, so that product quality is poor, affecting the host to use. Hydraulic hose assembly connector part by the joint core , jacket, union nut and hose components. Connector nut is coupled with supporting host , will not be discussed here . Common  Hydraulic hose fittings hose assembly broadly divided into two structural forms: the first joint portion of the structure is determined by a smooth cylindrical jacket and a small cone -shaped core and hose fittings composition ( Figure 1 ) . Figure 1 of this structure fitting jacket , the core processing is simple, easy to assemble , process performance, suitable for mass production . Hose connector is to rely on the hose connector core diameter hose up volume and coat on the outside diameter of the amount withheld to form a seal . Small cone -shaped connector core mainly by a small section of the cylindrical surface of the cone and form a seal .
