How to correctly choose the type and grade of Hydraulic Hose suitable for a specific hydraulic system?

In various industrial fields, hydraulic systems play a vital role. As a key component of hydraulic systems, the correct selection of Hydraulic Hose is essential for the efficient operation, safety and reliability of the system.
1. Understand the working requirements of hydraulic systems
First, we need to have a deep understanding of the working requirements of a specific hydraulic system. This includes factors such as the system's working pressure, flow, temperature range, fluid type, and working environment. Different hydraulic systems may vary greatly in these aspects, so an accurate understanding of these parameters is the basis for selecting the right hydraulic hose.
For example, for systems with higher working pressures, it is necessary to choose hydraulic hoses that can withstand high pressures; for systems working in high temperature environments, it is necessary to choose hoses with good high temperature resistance.
2. Types of hydraulic hoses
Braided hoses
Braided hoses are made of multiple layers of steel wire or fiber and have good pressure resistance and flexibility. This type of hose is suitable for most conventional hydraulic systems, especially those with high flexibility requirements. Braided hoses are usually more economical and relatively easy to install.
Wrap hose
Wrap hose is made by spiral winding of steel wire or fiber, which has higher pressure resistance and impact resistance. It is suitable for heavy hydraulic systems with extremely high working pressure, such as construction machinery, mining equipment, etc. The price of spiral hose is relatively high, but it performs well under harsh working conditions.
Thermoplastic hose
Thermoplastic hose is made of special plastic materials and has the advantages of light weight, corrosion resistance and wear resistance. It is suitable for some occasions with special requirements for weight and corrosion resistance, such as food processing, chemical industry, etc. However, the pressure resistance of thermoplastic hose is generally low and is not suitable for high-pressure systems.
3. Hydraulic hose grade
Hydraulic hose is usually divided into different grades according to its performance indicators such as pressure resistance, temperature range, corrosion resistance, etc. When selecting hydraulic hose, the corresponding grade of hose should be selected according to the specific requirements of the hydraulic system.
High pressure grade
High pressure grade hydraulic hose can withstand high working pressure and is usually used in heavy industrial equipment and construction machinery and other fields. These hoses usually adopt high-strength steel wire braiding or winding structure, with excellent pressure resistance and reliability.
Medium pressure grade
Medium pressure grade hydraulic hose is suitable for general industrial equipment and agricultural machinery and other fields. They have moderate pressure resistance and are relatively affordable. Medium-pressure hoses are usually made of steel wire braided structure, which can meet the requirements of most conventional hydraulic systems.
Low-pressure grade
Low-pressure grade hydraulic hoses are mainly used in some occasions where pressure requirements are not high, such as household appliances, small tools, etc. These hoses are usually made of fiber braided structure or thermoplastic materials, which are cheap and easy to install.
4. Consider the working environment
In addition to the working requirements of the hydraulic system and the type and grade of the hose, the working environment is also one of the important factors in selecting hydraulic hoses. For example, if the hydraulic system works in a harsh outdoor environment, it is necessary to choose a hose with good weather resistance and abrasion resistance; if the system operates in a corrosive environment, it is necessary to choose a corrosion-resistant hose.
In addition, factors such as the installation space and bending radius of the hose need to be considered. Make sure that the selected hose can bend freely in the installation space without excessive stretching or squeezing.
5. Choose a reliable supplier
Finally, it is crucial to choose a reliable hydraulic hose supplier. A reliable supplier can provide high-quality products, professional technical support and perfect after-sales service. When choosing a supplier, you can refer to factors such as its product quality certification, customer evaluation and industry reputation.
Correctly selecting the type and grade of hydraulic hose suitable for a specific hydraulic system requires comprehensive consideration of the system's working requirements, the type and grade of the hose, and the working environment. Through careful analysis and selection, we can ensure the efficient operation, safety and reliability of the hydraulic system, providing strong protection for industrial production and equipment operation.
