Classification of high-pressure hose:
High pressure hose is divided into high pressure steel wire braided hose production skills and high pressure steel wire wound hose.
High-pressure hose production process:
By mixing the lining rubber mixer according to the formula, the middle plastic and the outer plastic, extruded with the inner tube by the extruder, coated with a soft core release agent or (liquid nitrogen freezing method can also be done without the tube core); The calender presses a rubber sheet, adds it to the winding and cuts it to a custom width according to skill requirements. The coil is bound at the beginning and end (some preliminary winders require pre-prestressed prestressing of copper-coated steel wire or copper wire rope for coiled tubing or knitting machine containing an inner tube winder, two layers or copper wire rope between the intermediate rubber plate and the copper-coated steel wire of the synchronous coil winder and braiding machine). The outer rubber is extruded and then covered with lead sulfide or cloth; Vulcanization tank or salt bath after vulcanization. After vulcanization layer, spare tube core, reserved tube joint, sampling inspection.
High pressure hoses, equipment used, variety of materials, production skills and confusion. However, in recent years, hydraulic tubing production skills mainly made of plastic or thermoplastic elastomer materials can be simplified, but the material is high, or the rubber material is mainly used.
