Hose Assembly for Coal Mine
The coal mine rubber hose assembly is a high-performance and highly safe fluid conveying component specially designed for the extremely harsh underground environment of coal mines.
- Product Introduction
The coal mine rubber hose assembly is a high performance and high safety fluid conveying component, especially for the extremely harsh underground environment of coal mines. It is made by advanced technology with durable rubber hoses and special pipe fittings (core tubes, outer sleeves, retention rings, etc. It is the "blood vessels" of important equipment in coal mine such as hydraulic supports, shearer machine and roadheader for transmitting high-pressure hydraulic oil, emulsion, water and other media. It is a necessary core element of the safe production of coal mines.
The hose (hose) assembly is a common auxiliary device used in hydraulic systems.
Characteristic Use
High pressure hose assembly is generally composed of liquid-resistant synthetic rubber inner rubber layer, middle rubber layer, I**VI layer steel wire braided reinforcement layer and synthetic rubber outer rubber layer with good weather resistance. It is mainly used in mine hydraulic support, oil field mining, suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and various industrial departments mechanized, automated hydraulic system with certain pressure. And temperature based Petroleum based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) liquid. Water-based liquid (such as emulsion, oil-water emulsion, water) . Gas. Liquid transmission and other fields.
Product Structure And Features
Excellent laminated structure
High-pressure rubber hose assemblies typically have a multi-layer composite construction to deliver exceptional performance:
Inner rubber layer
It is made of liquid-resistant synthetic rubber and is in direct contact with the conveyed medium, playing the role of sealing, anti-corrosion and wear resistance.
Reinforcing layer
It is composed of high-strength steel wires of Grade I to Grade VI (this is a key structure) woven or wound together. It has an extremely high pressure-bearing capacity and resistance to pulse fatigue, and is the "skeleton" of the rubber hose.
Outer rubber layer
It is made of synthetic rubber which is resistant to weather and wear and protects the reinforcing layer from damage by external environments such as moisture, ozone and physical scratches.
Core performance characteristics
High pressure resistance
The design of the steel wire reinforcement layer can meet the requirements of various working conditions from medium pressure to ultra-high pressure.
Excellent pulse performance
Long service life suitable for dynamic systems with frequent pressure fluctuations.
Excellent flexibility and ease of use
It is convenient for pipe laying and installation in complex Spaces, and can absorb system vibration and noise.
Wide medium compatibility
Compatible with petroleum-based, water-based liquids and gases. Rubber compounds can be selected for different media being conveyed.
Assembly Meaning
Hose assembly is the technology and supply scheme of full range of connectors for specified working conditions. Including rubber tubes (or hard tubes), seals and connection accessories (such as joints, flanges, etc.)
