05 Application of hydraulic hose assembly R1 3/8" (BSP straight head + 90° elbow) and advantages of
I. Application and use conditions of hydraulic hose assembly R1 3/8"
Hydraulic hose assembly is a key component for transmitting high-pressure fluid in hydraulic system and is widely used in engineering machinery, agricultural equipment, mining machinery, ships, petrochemical industry and other fields. The R1 3/8" hydraulic hose assembly (BSP straight end and 90° elbow end) introduced this time is suitable for the following working conditions:
1. Main use
Engineering machinery: used for hydraulic oil circuit connection of excavators, loaders, cranes and other equipment, withstanding high pressure impact and frequent bending.
Agricultural machinery: hydraulic systems of tractors, harvesters and other equipment, adapting to harsh outdoor environments (such as mud, high temperature, vibration).
Industrial equipment: injection molding machines, die-casting machines, hydraulic pump stations, etc., to ensure stable transmission of high-pressure oil.
Mining machinery: rock drills, crushers, etc., wear-resistant and impact-resistant.
2. Typical use conditions
High-pressure environment: R1 hose is braided with single-layer steel wire, and the working pressure is usually 250300 bar, which is suitable for medium and high pressure hydraulic systems.
Bending installation requirements: The 90° elbow design is suitable for pipeline layouts with limited space, reducing hose twisting and extending service life.
Media compatibility: Suitable for hydraulic oil, lubricating oil, water glycol and other fluids, oil resistant and corrosion resistant.
Temperature range: Usually can work stably in an environment of 40°C to +100°C, and some models can withstand higher temperatures.
II. Advantages of LETONE hydraulic hose
LETONE hydraulic hose is a well-known domestic brand. Its R1 series hose has significant advantages in performance, durability and cost-effectiveness, and is suitable for various harsh working conditions.
1. High-strength steel wire braided layer
The use of high-quality high-strength steel wire braided layer ensures excellent high-pressure resistance and pulse resistance, reducing the risk of pipe explosion.
Compared with ordinary hoses, LETONE R1 hose has better fatigue resistance and is suitable for engineering machinery with high-frequency vibration.
2. High-quality synthetic rubber inner layer
The inner rubber layer is made of oil-resistant and wear-resistant synthetic rubber, which is resistant to hydrolysis and oxidation and prolongs the service life.
Low permeability design reduces hydraulic oil leakage and improves system efficiency.
3. Weather resistance and environmental adaptability
The outer rubber is UV-resistant and aging-resistant, suitable for long-term outdoor exposure.
Some models can be equipped with wear-resistant sheaths to prevent the hose from being damaged in gravel and metal friction environments.
4. Strict international standard certification
It complies with international standards such as ISO 1436, EN 853, SAE J517, etc. to ensure stable and reliable product quality.
It has passed professional certifications such as MSHA (mine safety certification) and DNV (classification society certification), and is suitable for special industry needs.
5. Customized service
Litong can provide customized hose assemblies with different lengths and connector combinations (BSP, NPT, JIC, etc.) to meet the needs of different equipment.
The 90° elbow design can reduce installation stress and avoid damage caused by excessive bending of the hose.
III. Selection and maintenance recommendations
1. Correct selection: Select the appropriate model according to the system pressure, medium, and temperature. R2/R3 multi-layer steel wire hose can be considered for high-pressure environments.
2. Installation precautions:
Avoid excessive bending of the hose, and the minimum bending radius should meet the standard.
Ensure that the joints are well sealed to prevent leakage.
3. Regular inspection:
Check whether the outer layer of the hose is cracked or bulged, and whether the inner layer is peeling.
Under high pressure and high frequency vibration conditions, it is recommended to replace it every 12 years.
R1 3/8" hydraulic hose assembly (BSP straight head + 90° elbow) is an ideal choice for medium and high pressure hydraulic systems, suitable for a variety of scenarios such as construction machinery and agricultural equipment. And Litong hydraulic hose has become a highly cost-effective domestic alternative with its advantages of high strength, oil resistance, weather resistance, and long life. Correct selection and maintenance can greatly increase the service life of the hose and ensure the stable operation of the hydraulic system.
