Hydraulic hose protection sleeve
Hydraulic hose protection sleeve also named hose protector, hydraulic hose sleeve spiral sleeve , PP spiral guard ,spiral hose guard. Is a polypropylene (PP), polyethylene (PE) or nylon (PA) as raw materials, the use of hot winding stereotypes extrusion process made of spiral guard warp. Hydraulic hose protection cover is a new alternative to traditional hose protection with metal protection spring ,it working Temperature Range is -60℉ to +210℉ (-50℃ to +100℃), The use of hydraulic equipment is very wide, used to reduce the hydraulic hose and metal parts of the friction, improve the life of rubber hose.
The inner surface of the hydraulic protective cover is generally flat, the outer surface is divided into two kinds of plane and arc. Hydraulic hose protective sleeve is wear resistance, anti-aging, anti-corrosion performance; more powerful on the outer surface of the hose anti-aging and anti-friction protection. Hydraulic hose protection sleeve relative to the hose protection products and other sheath products with more convenient and environmentally friendly energy saving effect.
Production equipment: hydraulic hose protective sleeve production equipment, including plastic extruder, jacket winding machine, curing tank and so on.
Hydraulic hose protective sleeve production is used in the heat setting process, generally divided into a two-time stereotypes and two stereotypes.
A stereotypes process: nylon or plastic granule material by plastic extruder heated plastic extrusion into a thin strip of long strips from the head die after extrusion without water cooling that is wrapped around the winding machine of different specifications of the mandrel And then cooled by cooling water after forming from the mandrel is formed into a spiral sheath.
Secondary molding process: nylon or plastic particles extruded through the extruder after the film into the cooling water cooling; after cooling the long winding and then wrapped around the different specifications of the mandrel; and then the mandrel into the curing tank Heating vulcanization. After a certain period of time out of the tank, from the mandrel can be molded.
