High-pressure wear-resistant hoses are a crucial component of hydraulic systems, used to transport high-pressure hydraulic oil and withstand significant pressure and friction. To ensure maximum performance, proper installation and maintenance are essential.
I. Key Points for Correct Installation
- Selecting the Appropriate Hoses
The selection of high-pressure wear-resistant hoses should be based on factors such as the hydraulic system’s working pressure, flow rate, and operating environment. Appropriate materials, specifications, and models should be chosen. Improper selection may lead to hose bursting, oil leaks, or wear.
- Rational Hoses Layout Design
The length, bending radius, and layout of the hose all affect its lifespan and performance. Excessive bending or exposure to non-axial forces such as shear and torsional forces should be avoided.
- Correct Hoses Installation
Hose installation should follow specific specifications and requirements, utilizing professional tools and equipment such as pipe cutters, clamp pliers, torque wrenches, and pipe presses. Hoses connections should be fitted with clamps, fittings, and O-rings to ensure leak-proof and secure connections.
- Control Torque and Pressure
Use a torque wrench to control the torque and pressure of clamps and fittings at hose connections. Avoid overtightening or loosening, which can lead to insecure hose connections or poor seals.
- Post-Installation Quality Inspection
After installation, check that hose connections are correctly installed, clamps and fittings are securely tightened, and there are no oil leaks to ensure hose quality and safety.
II. Key Points for Proper Maintenance
- Regular Hose Inspection
Regularly inspect the hose’s appearance, connections, and bending radius. Replace the hose immediately if wear or damage is found. Adjust and repair any loose connections or oil leaks.
- Keep Hydraulic Oil Clean
Impurities and contaminants in the hydraulic oil can affect hose life and performance. Change the hydraulic oil regularly and keep the hydraulic system clean.
- Avoid Excessive Vibration and Impact
Excessive vibration and impact can damage the hose. Take measures to avoid vibration and impact, such as installing shock absorbers and vibration dampers.
- Keep the hose dry
When storing or not using the hose for extended periods, it should be kept dry to prevent internal rust and corrosion, which can affect its performance.
- Regularly maintain the hose
Regular maintenance of the hose, such as applying rust inhibitors and lubricants, can extend its service life.
In conclusion, proper installation and maintenance are key factors in ensuring that high-pressure wear-resistant hoses perform at their maximum efficiency. During use, the condition of the hose should be closely monitored to ensure that the hose connections are secure and the seals are good. Problems should be identified and addressed promptly to extend the hose’s service life and ensure the normal operation of the hydraulic system.
