Water jet looms recycle most water, but consumption hinges on operation and maintenance practices:
1. The circulatory system determines the actual consumption
Closed recycling: 80-90% of the water after spraying is recycled through a filter/sedimentation tank, and the real consumption is the water taken away by evaporation and cloth surface
Filter residue with water loss: When cleaning the cotton wool in the water tank, each loom carries away about half a bucket of water each time it discharges (cotton residue contains water that is difficult to separate)
2. The latitude parameter directly affects the demand
High pressure jet consumes more water: When weaving heavy fabrics, it is necessary to increase the pressure and spray 30% more water than thin fabrics in the same amount of time
Large waste during shutdown and startup: the water pressure is unstable for the first 10 minutes after each restart, and some water overflows directly and cannot enter the circulation
3. Three major invisible water consuming black holes
| Problem Point | Water Loss Manifestation | Field Signs to Watch | Emergency Fixes |
| Nozzle Dribble | Continuous dripping during stops(≈1 cup/day/nozzle) | Puddle under nozzle at shift start | Tighten seals with cable ties;Wrap thread seal tape on threads |
| Filter Damage | Dirty water recirculation(Top-up frequency doubles) | Pump runs hotter;Float valve constantly refilling | Patch holes with window screen mesh;Bypass damaged section temporarily |
| Pipe Scaling | Reduced flow → Pressure spike(Forced high-pressure mode) | Pressure gauge flickering;Whining pump noise | Hammer pipes to dislodge chunks;Short-term vinegar flush (avoid acid!) |
4. Impact on workshop environment
Dry season: water evaporation accelerates, additional water tank needs to be replenished once a week
High humidity rainy season: Increased overflow of recycled water (condensation of water vapor in the air into the system)
