Use and maintenance of air-jet looms

 1. routine maintenance and processing

Maintenance work on the machine requires electric pumps, concentrated oil, the main motor cooling parts, the input shaft opening cam box, electromagnetic brake, feeler, scissors, leno, the temple and the treatment of side yarn catching routine maintenance.

2. overhaul and processing machine when

Check the side support ring rotation is flexible, wear, whether there is accumulation fly, yarn stop pin and whether the main drum interval 0.5 mm, pipe leaks, whether centralized oil spill, tubing for damage or bend, control box Are there internal accumulation fly, confirm whether the error frame height is within 2 mm, air filter exhaust pipe is smooth, the upper pinion whether there are flowers, bevel gear shaft opening means if there is yarn, filter the mesh is blocked, warp, whether easing shaft volume has yarn, wire insulation sleeve for damage, brake clearance is correct. Refueling nozzle parts, whether the tooth surface and the chain refueling and inspection heddle and heddle guides Open gear wear.

3. The half-yearly maintenance and processing

Need to check whether the winding and clean, if there is yarn marks and scars on the main drum, drum pin, internal yarn stop pin assembly is dirty, if there is an opening rope elongation or damage, whether mechanized return spring is damaged, the rope connecting seat bearing openings wear. Each belt tension level is appropriate, if there is damage, whether the sensors work properly, gear boxes, winding gear box, sent by the gearbox oil change, remove iron filings on the magnet opening cam box, whether the filter mesh congestion, whether stained with dirt reed, wind speed is normal, under the U-shaped bushing wear retractors whether within 2 mm, the main nozzle duct has bent, whether the children of the winding roller chains have extended, whether the planetary gear backlash normal planetary bobbin holder bushing wear whether O.5 mm or less, whether the planet bobbin shaft wear in 0.5 mm or less, planetary bobbin bushing wear whether O.5 mm or less, if the auxiliary nozzle marked with yarn marks, whether curved scissors device if there is oil and the like.

4. Inspection and processing time of year

The main nozzle standoff screws are loose, need to re-tighten the screws.

5. The two-year maintenance and processing time

Take-up roller, pressure roller and matte rubber for wear, the shaft portion of the wear by whether within 0.3 mm, the buffer performance is reduced, nylon bushings and buffer guide pin for wear, whether auxiliary nozzle dirty, for yarn scissors device side can correctly cut weft yarn stop pin assembly yarn stopper pin holes for wear, whether within 0.5mm, winding through parts of the cloth roll shaft wear, whether within 0.5 mm.

6. The three-year overhaul and processing time

Lubricating oil is less than a solenoid valve and the winding cloth roller is flexible rotation.

7. The seven-year overhaul time

Including the bearings, seals, gears, cams, bushings, stop yarn sales, the main motor and chassis, openings, warp, coiling, weft feeder relevant parts of the overhaul.

Second, long-term use after the loom need to preserve the contents of the various agencies and precautions

 (1) main section: loom after long-term use, the need to replace the driving portion of the crankshaft bearing oil seal.

(2) the opening section: the need for opening cam arm bearings, wire rope, back mechanized spring back mechanized arm bearing replacement.

(3) the timing belt replacement, oil filter cleaning.

(4) regular cleaning of the reed.

(5) The long weft measuring drum replacement of internal parts, stop yarn pin internal parts replacement, encoder cleaning.

(6) The main nozzle cleaning, filter cleaning, cleaning the solenoid valve and regulator repair, pipe inspection, configuration.

(7) servo motor repair and replacement, repair and replacement of buffer internal parts.

(8) Check brake winding roller, chain tensioning wheel adjustment pin and replace, maintenance and replacement of the friction plate, disc. Check and replace matte eraser.

(9) Check and replace selvedge planetary gears, bearings bobbin, the yarn guide arm shaft couplings.

(10) Check and replace weft cable.
