A talk on the characteristics of high pressure steel wire winding hose
The structure of high-pressure steel wire winding hose is mainly composed of liquid-resistant styrene-butadiene rubber inner adhesive, middle adhesive layer, I, II and III stainless steel wire braid layer, and weather-resistant styrene-butadiene rubber outer adhesive.
The inner adhesive has the ability to bear the transmitted material and ensure that the stainless steel wire will not be corroded. The outer adhesive maintains that the stainless steel wire will not be damaged. The stainless steel wire layer is the skeleton material and plays an improving role.
The main purpose of high-pressure steel wire winding hose: high-pressure steel wire to improve high-pressure oil pipe is mainly used in coal mine hydraulic support, oil field development, it is suitable for transportation of petroleum-based (such as mineral engine oil, soluble oil, gear oil, gasoline and diesel oil, grease) and aqueous liquid (such as emulsified oil, water and oil emulsion, water) with certain pressure and humidity in construction, lifting and transportation, metallurgical industry casting, mining machinery and equipment, ships, injection molding machinery and equipment, agricultural machinery, various numerical control lathes and mechanical automation and automation technology hydraulic press systems of various industrial departments..
the use of high pressure steel wire winding hose:
High-pressure steel wire wound rubber hose is mainly used in mining hydraulic support, oil and gas field excavation, construction engineering construction, lifting and transportation, metallurgical industry forging, mining machinery and equipment, ships, injection machinery and equipment, agriculture and animal husbandry, various numerical control lathes, various industrial machinery automation, automatic hydraulic press system with a certain pressure and humidity of crude oil base.
Matters needing attention when using high pressure steel wire wound hose
1. The high temperature and high pressure steel wire winding hose have a short cycle when the working temperature is high, so pyrogen should be avoided as much as possible. If necessary, rubber gloves plastic hose or heat insulation board can be used to avoid the malignant change of plastic hose under high temperature.
2. Avoid surface friction: it is not necessary to touch other pipelines during installation and use to avoid friction and cracking. When friction occurs after cross-type and work, protective equipment (plastic hose iron clamp/torsion spring) should be selected.
3. Bend, the emergency commodity bending radius R(9~10)D(D is the outer diameter of the hose) to avoid about 6 times the outer diameter of the pipe from the connector to the straight curve section.
4. When installing the high-pressure steel wire winding hose, do not tighten the application during assembly, and a certain length allowance is required. There is no relative movement on both sides, and the relaxation of the plastic hose must be maintained. After the plastic hose is reduced, the size and aperture will change, so the plastic hose will rise under pressure and the compressive strength will decrease.
5. In the equipment link, to prevent plastic hose deformation, plastic hose slight distortion will also lead to reduced compressive strength or loose interface.
6. The bend of the plastic hose and the hose joint are assembled in the same plane to avoid distortion. In particular, if the RF connectors at both ends of the plastic hose are located in two different planes, the iron clamp is installed in a moderate position, and the plastic hose is divided into two categories, so that each part is located in the same plane.
7. If the core components are equipped with rubber hoses, regular maintenance and replacement are proposed.
From the product quality to see whether to achieve positive vulcanized rubber, the way is less sulfur or less sulfur. Due to the manufacture of vulcanization treatment is not very good will also lead to product characteristics are not up to standard, uneven thickness of rubber hose, harm the internal adhesive.
