Yuqorī bosim yoqilg‘i shlanglari odatda yuqori sifatli materiallardan tayyorlanadi, chunki ularning bosimga va issiqlik ta'siriga bardosh berishi zarur. Asosan, elastomerlar, qattiq plastiklar va boshqa maxsus materiallar ishlatiladi, bu esa shlangning mustahkamligi va chidamliligini ta'minlaydi. Shlanglar ichida maxsus plyonka yoki qoplama bo‘lishi mumkin, bu esa yoqilg‘ining o‘tish jarayonida shlangning ichki devorini himoya qiladi va korroziya ta'siridan saqlaydi.
Braided hoses are invaluable components in a wide range of engineering and manufacturing applications. Their strength, flexibility, and durability make them a top choice across various industries, from automotive to aerospace. By understanding the unique characteristics and benefits of braided hoses, as well as the factors to consider when selecting them, you can ensure optimal performance and reliability in your applications. Choosing the right braided hose plays a crucial role in enhancing efficiency and safety across projects, making it an essential consideration for engineers and manufacturers alike.
Hand crimpers are particularly valued for their portability and ease of use. Unlike larger hydraulic crimping machines, hand crimpers can be operated manually, making them ideal for on-site repairs and installations. This mobility allows technicians to efficiently handle maintenance tasks in various environments, such as construction sites, automotive workshops, and agricultural fields.
Hydraulic hoses play a critical role in various industrial applications, providing the necessary means to transmit hydraulic fluids. One of the established standards governing the manufacturing and testing of hydraulic hoses is EN 857. Specifically, EN 857 1SC pertains to a class of hydraulic hoses designed to operate under specific conditions of pressure and temperature. This article will delve into the intricacies of the EN 857 1SC standard, its construction, applications, and significance.
Secondly, hand crimpers are cost-effective. Unlike larger hydraulic machines, which can be prohibitively expensive, hand crimpers are relatively affordable. This accessibility enables smaller businesses and independent technicians to invest in quality tools without significant financial strain. Moreover, the ability to perform in-house assembly and repairs reduces reliance on external services, further saving costs in the long run.
Since hose may change in length from +2% to -4% under the surge of high pressure, provide sufficient slack for expansion and contraction.
Never use a bending radius less than the minimum shown in the hose specification tables. The bending radius of the hose should be far away from the hose fitting (A＞1.5R)
Hose bending radius is bigger when it is in motion.
Choose proper fittings, avoid twisting in hose lines bent in two planes.
Avoid twisting in hose by use clamp properly.
Hose should not be twisted, hose is weak when installed in twisted position. Also pressure in twisted hose tends to loosen fitting connections. Design so that machine motion produces bending rather that twisting.
Leave proper length when the hose in connected
Choose proper fittings, avoid too small bending radius and excess force.
Choose proper fittings, avoid excessive hose length.
Reuse friction, avoid hose touching the object directly or far away from the object.
Hose Active Working Pressure Working Life
As shown , when active working pressure in 1.25 times recommended working pressure, the hose working life is only half of i under working in recommended working pressure.
Store Conditions of the Assembly.
1.If possible, the storing temperature range is within 0-30 ℃. During storing, temperature should not exceed 50℃
2.The storing areas can not place equipment within can produce ozone.For example mercury vapour lamp, high voltage electric device and other equipment which can produce spark or set out electricity.
3.Can not be placed with erosive products or exposed over gas-volatile on these products.
4.Far away from heat source and equipment which can produce electric field or magnetic field
5.Avoid sunshine or strong artificial light source
6.Avoid to touch the sharp objects or the ground
7.Guarantee against rodent attacking.
8.Observe the rule of “First in, then first out”
