First, regular maintenance 

1. Routine maintenance and processing of maintenance workers need to machine the electric pump, the central fuel supply, the main motor cooling parts, open cam box input shaft, electromagnetic brake, weft, scissors, twisted edge, And trailing edge processing yarn for routine maintenance.

2. Check the air jet loom machine and check the edge of the ring is flexible, whether wear, whether the accumulation of flying, only the pin and the main drum interval is 0.5 mm, whether the trachea leak, focus on oil is oil, tubing Whether there is damage or bending, control box inside the accumulation of flying, to confirm whether the height of the heald frame within 2 mm, the filter exhaust pipe is smooth, whether the shaft pinion flying, opening device bevel gear shaft Whether there is a yarn, oil filter on the mesh is blocked, send by, loose warp whether the volume of yarn, wire insulation sleeve is damaged, the brake clearance is correct. Nozzle parts refueling, open gear teeth and the chain of refueling and check the heald frame and heel frame on whether there is wear.

3.  Semi-term maintenance and processing need to check the winding and whether the clean, the main drum, drum on the drum marks and scars, whether the inside of the yarn pin is dirty, open wire rope is elongated or damaged, back spring There is damage, open wire rope connecting seat bearing wear. Whether the belt tension is appropriate, whether the damage, the sensor is working properly, transmission gear box, take the gear box, send gear box to replace the oil, remove the open cam box magnet iron, filter mesh Clogged, reed whether it is stained with dirt, the wind speed is normal, pull the hook U-shaped liner wear is less than 2 mm, the main nozzle pipe is bent, winding roller chain is extended, planetary gear teeth gap Normally, whether or not the wear of the planetary bobbin bushings is within 0.5 mm, whether or not the planetary bobbin shaft wears within 0.5 mm, whether or not the planetary bobbin bush wears within O.5 mm, Marks, whether to bend, whether the scissors device oil and so on.

4. If the screws on the main nozzle feet are loose for one year and need to be tightened, tighten the screws.

5.  If the wear and tear of the take-up roller, the press roller and the rough surface rubber are damaged during the two years, whether the wear of the shaft shaft is within 0.3 mm, the performance of the buffer is reduced, the nylon bushing and the buffer are guided Whether the pin is worn, whether the auxiliary nozzle is dirty, the yarn side scissors device can correctly cut the weft yarn, the yarn pin pin is not worn, whether it is within 0.5mm or less, Wear, whether within 0.5 mm.

6.  Three years of maintenance and handling of solenoid valve oil is insufficient and winding roller is flexible rotation.

7. Overhaul of seven years, including the bearings, oil seals, gears, cams, bushings, yarn deduction, the main motor and rack, opening, send by, coiling, weft feeder related parts of the maintenance.

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

(1) the main drive part: long-term use of the loom, you need to replace the part of the crankshaft bearing seal.

(2) opening part: the need for cam opening arm bearings, wire rope, back to the reed, back to the arm bearing replacement.

(3) synchronous toothed belt replacement, oil filter cleaning.

(4) regular cleaning reed.

(5) measuring long storage tank drum parts replacement, only the internal parts of the pin replacement, encoder cleaning.

(6) cleaning the main nozzle, filter cleaning, solenoid valve and pressure relief valve repair, trachea inspection, configuration.

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

(8) Check the winding brake roller, chain, tension wheel, adjust the pin and replace the friction plate, tray maintenance and replacement. Rough surface rubber check and replacement.

(9) Check and replace the twisted planetary gears, bobbin bearings, guide arm shaft, coupling.

(10) Check and replace the trailing cable.
