As an important power transmission method in modern industry, the connection quality of hydraulic pipes and joints, the core component of hydraulic systems, is directly related to the operating efficiency and safety of the entire system. There are many ways to connect hydraulic pipes and joints, each of which has its unique advantages and applicable scenarios. This article will introduce several common connection methods and their characteristics in detail.

 

1. Welding connection

Welding connection is to weld the joint and the pipeline into one at high temperature to form a permanent connection. This connection method has the characteristics of high connection strength and good sealing performance, and is suitable for high pressure and high temperature conditions. Welding connection is widely used in heavy industrial fields such as engineering machinery and metallurgical equipment. However, the welding quality is greatly affected by the technical level of the operator, and it is inconvenient to disassemble. Once a problem occurs, it is difficult to repair.

 

 

2. Card sleeve connection

Card sleeve connection uses the elastic deformation of the card sleeve to achieve sealing and tightening, and is easy and quick to install. This connection method is widely used in medium and low pressure hydraulic systems, especially in occasions where frequent disassembly is required, such as laboratory equipment, small machinery, etc. The advantage of the ferrule connection is that it is easy to install, but the ferrule has high requirements on the quality of the pipe material, and the reusability is limited. It may become loose or leak after long-term use.

 

3. Flared connection

The flared connection achieves sealing by expanding the pipe end and matching the conical surface of the joint. The structure is simple and reliable. This connection method is widely used in automotive hydraulic systems and low-pressure pipelines, and is suitable for the connection of small-diameter pipelines. The advantages of the flared connection are simple structure and low cost, but it has high requirements on the processing accuracy of the pipe end and relatively low pressure resistance, which is not suitable for high-pressure systems.

 

4. Flange connection

The flange connection is fastened with bolts and is suitable for the connection of large-diameter pipelines. This connection method is widely used in ship hydraulic systems and large engineering machinery, and has the advantages of strong bearing capacity and easy disassembly. The flange connection is suitable for high pressure and large flow occasions, but it occupies a large space, has high installation accuracy requirements, and needs to check the tightening of the bolts regularly to prevent leakage.

 

5. Quick-change connector connection

Quick-change connector connection is a connection method that is easy to disassemble and install quickly. It is widely used in occasions where equipment needs to be replaced frequently, such as agricultural machinery, construction equipment, etc. Quick-change connectors are easy to operate and have good sealing performance, but they are expensive and have high requirements for the use environment. They are not suitable for extreme working conditions.

 

Liwang hose assembly is a high-performance hydraulic hose connection method that is widely used in various hydraulic systems. Liwang hose assembly is made of high-quality rubber material and has excellent oil resistance, corrosion resistance and wear resistance. Its joint part usually uses high-quality metal material to ensure the firmness and sealing of the connection.The advantages of Liwang hose assembly are its flexibility and durability. The hose can be bent and twisted to adapt to complex installation environments and reduce damage caused by vibration and impact. In addition, Liwang hose assembly has high pressure resistance and is suitable for high-pressure hydraulic systems. It is easy to install and maintain, which greatly reduces the maintenance cost of the system.

 

There are many ways to connect hydraulic pipes and connectors, and each method has its specific application scenarios and technical requirements. Choosing the right connection method can not only improve the operating efficiency of the hydraulic system, but also extend the service life of the equipment and reduce maintenance costs. Therefore, a deep understanding of the characteristics and applicable scope of various connection methods is of great significance for the design and maintenance of hydraulic systems. As a high-performance connection method, Liwang hose assembly plays an increasingly important role in modern hydraulic systems. Its excellent performance and reliability make it the first choice in many application scenarios.
