Affecting high pressure steel wire spiral hydraulic hose connector assembly properties of structural and process factors

Affecting high pressure steel wire spiral hydraulic hose connector assembly properties of structural and process factorsWith the development of EHV power hydraulic machinery, for high pressure steel wire spiral hydraulic hose assemblies demand is growing. Generally small diameter hose assembly with steel wire braided hose, large, medium diameter winding pipe with steel wire. High pressure steel wire spiral Hydraulic pipe fittings hose assemblies is higher than the working pressure 31.5MPa, mainly above 25 diameter wire winding hose assembly. Ideal for high pressure steel wire spiral hose assembly and hose connections must be between between devices with good sealing performance, assembly during use may not cause leakage, pipe fittings and hose without pulling off fittings must have good medium flow performance and small form factor. A high pressure steel wire spiral hydraulic hose affect assembly quality factor EHV wire spiral hydraulic hose assemblies structure shown in Figure 1. 1. Winding hose 2. Sleeve 3. Core 4. Nut Figure 1 hydraulic hose assembly assembly structure affect the quality of many factors. In many factors, hose assembly manufacturing quality is good or bad is the basis of quality. The mechanical properties of plastic material (high hardness, high elongation strength, low compression set, etc.) is a prerequisite to ensure the quality of assembly. The geometry of the metal pipe fitting, and the amount of compression within the plastic matching and withholding technology are all important factors determine the quality of assembly. 2 Relationship between structure and properties of assembly
