The high-pressure hose in the hydraulic system plays a vital role. In addition to the strict selection of material selection for high-pressure hose assembly, the crimping joint process is particularly important. When making steel wire braided high-pressure hose assemblies, many new employees are prone to unintelligent operation. The following is a brief description of the specific quantitative details of the high pressure hose crimping amount.
Check before crimping: whether the hose and the connector core are installed in place; whether the front end of the sleeve enters into an annular groove cut out of the outer cylindrical surface of the core, and whether the tightness is appropriate; if the tightness is too tight, the inner hole of the connector core will be deformed and the hose will be buckled. Injury, too loose, the joint will be pulled out when the hose is under pressure. To grasp the buckle amount of the joint jacket, it is necessary to calculate according to the change of the inner diameter of the high pressure hose and the outer diameter of the high pressure hose wire layer and the compression ratio of the high pressure hose.
