Waterjet Loom Maintenance, Water Quality and Common Faults

Create daily and periodic checks based on running hours and factory conditions. Clean the loom and water circuit, check oil, fasteners, belts, nozzle direction, scissors, leno devices, and the weft detector. Record unusual sound, vibration, alarms, and fabric defects so small changes can be noticed early.

• Cleaning, water filtration, and drainage
• Lubrication points, oil level, and oil condition
• Fasteners, anchors, belts, and moving links
• Nozzle direction, scissors, leno devices, and weft detector

If a fault appears, first identify the system involved. Common problem areas include scissors, leno tension, nozzle direction, feeder or belt position, weft detection, and pump flow after a fabric change. Check the mechanical condition and timing before altering several settings. Finding the cause is more reliable than repeated adjustment.

When insertion becomes weak or unstable, inspect the plunger, spring, cam linkage, check valves, nozzle, clamp, timing, remaining water, and shed. Higher pressure should not be used to hide a worn part, incorrect timing, poor yarn preparation, or a blocked jet path.

Changes in water quality can affect the pump, nozzle, filtration, corrosion risk, fabric appearance, and running stability. Monitor filtration and changes in hardness, pH, conductivity, suspended solids, and biological growth. Water treatment should be based on the actual local source rather than one universal value.

Before production begins, correct leveling, anchoring, alignment, power, water, drainage, and reference-fabric settings should establish a reliable baseline. Operators should understand safe operation, style changes, alarms, cleaning, and daily checks. Documentation, critical spares, warranty, remote support, and on-site service should also be confirmed before shipment.
