Comprehensive analysis of hydraulic oil hoses (detailed articles)

The hydraulic oil hose is a very important part of the hydraulic transmission system, and its function is to deliver hydraulic oil to realize hydraulic transmission. Hydraulic oil hose is a high-pressure rubber hose, usually made of rubber materials, such as commonly used nitrile rubber, etc., used to transmit liquid under high pressure. The diameter and wall thickness of the hydraulic oil rubber hose are very critical parameters in the design, and these parameters determine the pressure resistance and life of the hydraulic hose. This article will deeply discuss the relevant knowledge of hydraulic oil hoses, including the types, materials, design and applications of hydraulic oil hoses, in order to provide readers with a comprehensive understanding. #Hydraulic hose#

1. Types of hydraulic hose

According to the material, the hydraulic oil hose is divided into high-pressure steel wire braided hydraulic oil pipe and cloth type rubber hydraulic oil pipe. Among them, steel wire braided hydraulic hose is the most widely used, has high strength and toughness, can withstand high pressure and impact load and has good thermal conductivity, and is suitable for high temperature and high pressure environments.

Hydraulic oil hoses are divided into low-pressure hydraulic oil hoses and high-pressure hydraulic oil hoses according to the working pressure. The working pressure of the low-pressure hydraulic oil hose is generally below 16MPa, and it is used in low-pressure hydraulic systems, such as ships and agricultural machinery. The working pressure of the high-pressure hydraulic oil hose is above 16MPa, and it is used in high-pressure hydraulic systems, such as machine tools and construction machinery.

2. Design of hydraulic hoses

The design of hydraulic oil hoses needs to consider many factors, including working pressure, flow rate, temperature, vibration, corrosion, etc. The diameter and wall thickness of the hydraulic oil hose are the most critical parameters in the design, which need to be determined according to the working pressure and flow. Typically, the smaller the diameter of the hydraulic hose, the higher its operating pressure. The wall thickness needs to be determined according to the strength and toughness of the hydraulic oil hose material. Generally, it should be ensured that it is not easily deformed and broken under the working pressure.


Internal steel wire braid
The connection method of the hydraulic oil hose is also very important, generally divided into welding connection, ferrule connection and flange connection. The welding connection has the characteristics of firm connection and good sealing, and is suitable for high-pressure hydraulic systems. The ferrule connection is suitable for low-pressure hydraulic systems, and has the characteristics of convenient installation and easy replacement. The flange connection is suitable for large-diameter hydraulic oil hoses, and has the characteristics of firm connection and easy disassembly.


Mechanical equipment hoses
3. Application of hydraulic hoses

Hydraulic hose is widely used in hydraulic systems in machinery, engineering, agriculture, ships, aviation and other fields. Common applications include:

1. Mechanical field: hydraulic oil hoses are used in various machine tools, cranes, excavators, loaders and other mechanical equipment to realize hydraulic transmission of working parts.

2. Engineering field: hydraulic oil hoses are used in various construction machinery, road machinery, bridge machinery and other equipment to realize hydraulic transmission and control.

3. Agricultural field: hydraulic oil hoses are used in agricultural machinery, such as tractors, harvesters, sprinklers, etc., to realize hydraulic transmission and control, and improve agricultural production efficiency.

4. Ship field: Hydraulic oil hoses are used in the hydraulic system of ships, such as steering gear, cranes, windlass, etc., to realize the power and control of ships.

5. Aviation field: Hydraulic oil pipes are used in aero-engines to realize hydraulic power conversion and control to ensure the safety and reliability of aircraft.


Hose assembly
Hydraulic hose has a wide range of applications, but the following points need to be paid attention to in use:

1. The installation and connection of hydraulic oil hoses must comply with relevant standards and specifications to ensure firm connections and reliable sealing.

2. The operating environment of hydraulic oil hoses should be dry and clean to avoid pollution and corrosion.

3. The operating temperature of the hydraulic oil hose should be within the allowable range of the material, and avoid excessively high or low temperature affecting performance.

4. The working pressure and flow rate of the hydraulic oil pipe should be within the design range to avoid overloading and overloading.

5. Regular inspection and maintenance of hydraulic oil hoses is very important. Check whether there are cracks, deformation, corrosion and other problems in the pipes, and replace or repair them in time.


construction machinery
In short, as an important part of the hydraulic transmission system, the hydraulic oil hose plays an important role in improving the production efficiency and safety of machinery, engineering, agriculture, ships, aviation and other fields. The type, material, design and application of hydraulic hose require careful consideration to ensure it can withstand the challenges of the working environment.
