What details should be paid attention to during the installation of Hydraulic Hose to ensure sealing and safety?

In the hydraulic system, Hydraulic Hose plays a vital role. It is responsible for transmitting high-pressure fluids to ensure the normal operation of the system. However, if you do not pay attention to details during the installation process, it may cause leakage, rupture and other problems, which will affect the sealing and safety of the system.
1. Choose the right hydraulic hose
Before installing the hydraulic hose, you must first choose the right hose. This includes considering factors such as the system's working pressure, temperature range, fluid type, and installation environment. Choosing a suitable hose can ensure that it can withstand the required pressure and temperature during operation, while being compatible with the fluid and adapting to the requirements of the installation environment.
For example, for high-pressure systems, hoses with sufficient pressure resistance should be selected; for high-temperature environments, high-temperature resistant hoses should be selected; for corrosive fluids, corrosion-resistant hoses should be selected.
2. Check the hoses and connectors
Before installation, carefully check the quality of the hydraulic hoses and connectors. Check whether the hoses are damaged, cracked, deformed, and whether the connectors are damaged, rusted, etc. If any problems are found, the hoses or connectors should be replaced in time to ensure sealing and safety after installation.
In addition, check whether the length of the hose is appropriate. A hose that is too long may cause excessive bending and twisting during the operation of the system, affecting the flow of the fluid and the life of the hose; a hose that is too short may cause installation difficulties or be overstretched during the operation of the system, increasing the risk of leakage and rupture.
3. Correctly install the joint
The installation of the joint is a key link in the installation process of the hydraulic hose. Correctly installing the joint can ensure the sealing between the hose and the joint and prevent leakage. Here are some precautions for installing the joint:
Use appropriate tools
When installing the joint, use appropriate tools such as wrenches, sockets, etc. Avoid using tools that are too large or too small to avoid damaging the joint or hose.
Tighten the joint according to the correct torque
When tightening the joint, follow the torque value provided by the manufacturer. A loose joint may cause leakage, while a tight joint may damage the hose or joint.
Ensure that the joint is installed in the correct direction
Some joints have specific installation directions. Make sure that the joint is installed in the correct direction to ensure sealing and safety.
4. Avoid excessive bending and twisting
When installing hydraulic hoses, avoid excessive bending and twisting. Excessive bending and twisting can damage the steel wire reinforcement layer inside the hose, reducing the hose's pressure resistance and life. At the same time, excessive bending and twisting may also affect the flow of fluid and increase the resistance of the system.
Generally speaking, the bending radius of the hydraulic hose should not be less than its minimum bending radius. During the installation process, accessories such as elbows and joints can be used to change the direction of the hose to avoid excessive bending and twisting.
5. Fix the hose
In order to ensure the stability of the hydraulic hose during the operation of the system, the hose should be fixed in place. Accessories such as pipe clamps and brackets can be used to fix the hose to the machine or equipment to prevent the hose from shaking or rubbing during operation.
Be careful not to fix the hose too tight or too loose. Too tight fixation may cause the hose to deform under pressure, affecting its sealing and life; too loose fixation may cause the hose to shake during operation, increasing the risk of leakage and rupture.
6. Perform a pressure test
After the installation is completed, a pressure test should be performed to ensure the sealing and safety of the hydraulic hose and joints. The pressure test can be performed using special test equipment according to the working pressure of the system. During the test, carefully observe whether the hose and joint have leakage, deformation and other problems. If any problems are found, they should be repaired or replaced in time.
When installing hydraulic hoses, pay attention to details such as selecting suitable hoses, checking hoses and joints, correctly installing joints, avoiding excessive bending and twisting, fixing hoses, and performing pressure tests. Only in this way can the sealing and safety of hydraulic hoses be ensured and the normal operation of the hydraulic system be guaranteed.
