Hydraulic hoses are also used in mine hydraulic support, oilfield mining, suitable for engineering construction, lifting transport, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and industrial sectors mechanized, automated hydraulic system With a certain pressure and temperature of the petroleum-based liquid, water-based liquid, gas and other liquid transmission.
Hydraulic oil is the energy transfer medium when the hydraulic station is working, and the transmission of the medium requires high pressure tubing, so the quality of the hydraulic hose may affect the work of the hydraulic system. Hydraulic hose pressure, the national standard requires the test pressure is the working pressure Of the 2 times, the burst pressure is generally 3-4 times the working pressure is qualified; simple appearance inspection method: see the appearance of its cross-section of the brightness, high brightness for the top grade, and nail pinch its gum good good.
