Design and Experimental Verification of Pressurized Cylinders in Hydraulic Rubber Hose Pressure Washers

Hydraulic rubber hoses are subject to great hydraulic impact during the actual working process, which causes a potential safety hazard. Therefore, it is necessary carry out pressure tests on hose assemblies ensure its quality, so providing high for has become key technology of this problem. Aiming at solving problem detection resistance in cleaning machines, paper analyzed pressurization mechanism pressurized cylinder and proposed method continuous pressurization. This also theoretically expansion hose, conclusion that maximum capacity (hose size Φ25 mm × 6 m), volume water required provide from 10 MPa 100 0.59 L. The was designed checked by finite element method. It concluded stress concentrated bottom high-pressure chamber, outlet hole barrel chamber weakest part cylinder. performance supercharging verified experiments, proves feasibility, rapidity stability
