- Hortumu bağlayın: Thread the hose fittings onto the corresponding ports of your air-operated equipment. Hand-tighten first, then use an appropriate wrench to secure the connection. Avoid over-tightening, which can damage threads.
- Sızıntı Testi: After connecting, slowly introduce the fluid or air pressure into the system. Check all connections for leaks using a leak detection solution or by listening for air hissing. Address any leaks immediately by re-tightening or re-sealing connections.
Safety Note: Always ensure the system is depressurized before attempting to connect or disconnect the hose assembly. Wear appropriate personal protective equipment (PPE) such as gloves and eye protection during installation.
4. Çalıştırma Yönergeleri
The HA-7325 Fluid Hose Assembly is designed for efficient and safe fluid transfer. Adhere to the following guidelines during operation:
- Sıvı Uyumluluğu: This hose is compatible with a wide range of materials, including but not limited to: resins, solvents (latices, epoxies, urethanes, alkyds, primers, acrylics, ketone, MEK, acetone, polyesters, silicones, bitumastic coatings, oil and water-based paints, lacquers, latex coatings, toluene, turpentine, naptha). Always verify compatibility with specific chemicals if unsure.
- Sıcaklık Sınırları: Do not expose the hose to temperatures exceeding 150°F (65°C). Operating outside this range can compromise hose integrity and lead to failure.
- Basınç Limitleri: While the hose features high tensile strength, always operate within the pressure limits specified by your air-operated equipment and the hose's design. Avoid sudden pressure surges.
- Kıvrılmalardan kaçının: Ensure the hose is laid out without sharp bends or kinks during operation, as this can restrict flow and cause premature wear.
- Hasarlardan Korunma: Protect the hose from sharp objects, abrasive surfaces, and heavy loads that could cause punctures or crushing.
5. Bakım ve Özen
Regular maintenance extends the lifespan and ensures the safe operation of your fluid hose assembly:
- Temizlik: After each use, especially when transferring corrosive or sticky materials, flush the hose thoroughly with a compatible cleaning agent or water to prevent buildup and clogging. Ensure all residue is removed.
- Denetleme: Periodically inspect the entire length of the hose for signs of wear, cuts, abrasions, bulges, or cracks. Pay close attention to the areas near the fittings.
- Fitting Check: Regularly check the tightness of all connections. Re-tighten if necessary to prevent leaks.
- Depolamak: Store the hose in a clean, dry, and cool environment, away from direct sunlight, extreme temperatures, and harsh chemicals. Coil the hose loosely to prevent kinking.
- Yenisiyle değiştirme: Replace the hose assembly immediately if any damage is detected or if it shows signs of degradation (e.g., hardening, softening, cracking).
6. Sorun Giderme
This section addresses common issues you might encounter with your HA-7325 Fluid Hose Assembly:
