  • Coal mine hydraulic support hose

    1. Product structure: Hose consists of inner rubber layer, middle rubber layer, steel wire braided layer and outer rubber layer. 2. Product use: Widely used in coal mining, single hydraulic props, hydraulic supports, suspensions in mines and roadways. Pressure support of the integrated coal mining system; to ensure the fixing of the safety roof of the mine and the safe advancement and production of the comprehensive mining system. Suitable for conveying hydraulic fluids such as alcohol, hydraulic oil, fuel oil, lubricating oil, water, emulsions, hydrocarbons, etc. to achieve high-pressure fluid transmission or hydraulic power transmission. Our company has signed strategic cooperation agreements with a number of large coal mine machinery factories, and is a supplier of hydraulic pipelines for hydraulic integrated coal mining systems. Our company has a multi-mining coal mine safety mark certificate [MA], and its products comply with GB / T3683--2011, GB / T10544--2003, MT / T98--2006 and other national standards and industry professional standards. 3. Product characteristics: high wear resistance, high static pressure strength, high tensile strength, good impact resistance, rigidity, flexibility, corrosion resistance, aging resistance, temperature resistance (-40 ℃ ~ 100 ℃), transportation Reliable performance. 4. Due to the special environment of coal mines and mines, the mine pipeline must have the basic characteristics of antistatic and flame retardant. On the one hand, due to the presence of acidic or alkaline solutions in coal mines, it is highly corrosive. Therefore, if the pipeline can work under the hold time of the mine, it must have acid and alkali resistance. 5. Technical performance 1. Sealing performance: no less than 1.5 times the standard rated working pressure of the hose, no leakage. 2. Pulse life: no less than 200,000 times. 3. Blasting test: not less than 4 times the design pressure. 4. Flame retardant performance: The average time of flame or glow is ≤30s. 5. Antistatic performance: surface resistance ≤ 2.5 × 10.
