Applications of 1% and 4% High Pressure Hoses

1. Avoid Kinks Always unwind your hose fully and avoid sharp bends that could lead to kinking. Use hose reels or hangers to store hoses properly.

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.

Hydraulic rubber hoses are composed of several layers, each serving a unique purpose. The innermost layer is usually made of synthetic rubber, which is designed to withstand the pressure of the hydraulic fluids. This inner lining is often resistant to various chemicals, ensuring longevity in harsh operating environments. The next layer typically consists of reinforcement fabric or braided steel wires, enhancing the hose's strength and flexibility while preventing it from bursting under pressure.

Moreover, these hoses are commonly used in automotive and aerospace industries. In automotive workshops, they assist in cleaning and preparing metal parts for painting or repair. In aerospace, they help maintain and restore the integrity of aircraft components by removing debris and contaminants that could compromise safety and performance.

- Agriculture Agricultural equipment like tractors and harvesters depend on hydraulic systems for various functions, such as lifting and steering. High-pressure hoses are essential for ensuring these systems operate smoothly and efficiently.

- Emergency Shut-off Valves High pressure propane lines should be equipped with emergency shut-off valves that can quickly halt the flow of gas in case of an emergency.

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”

4. Integrated Hoses Certain steam cleaner models offer integrated hoses that are built into the machine, providing a compact design but may limit flexibility depending on the model.

There are several advantages to using hydraulic hose hand crimpers. Firstly, they offer a high level of precision. Many hand crimpers come with adjustable settings, allowing users to achieve the exact pressure required for different hose and fitting combinations. This customization ensures the integrity of the connection while minimizing the risk of damage to either component.

Functionality of Hydraulic Hose Hand Crimpers

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.

Conclusion

In agriculture, hydraulic hoses connect tractors and other farming machinery to power implements like plows, seeders, and harvesters. Their reliability can significantly impact productivity during planting and harvesting seasons, where downtime can result in lost yields and increased operational costs.
