Precautions for starting the water jet loom after a long period of shutdown

1. The main work and operation points when the loom is shut down

①When the machine is shut down, the silk woven on the machine must first be left off the machine to prevent it from being placed on the machine for a long time, damp and moldy.
② Rinse the reed and the fallen slurry accumulated on the healds with water, and try to clean them as much as possible to lay a good foundation for restarting the machine in the future.
③Relax the warp tension, remove the heavy hammer, and shake the heald frame into a flat condition to prevent the warp from being stretched by the opening for a long time.
④ Put down the water baffle and waterproof cover on the loom and cover it.
⑤ Raise the pinch roller lifting rod to prevent the pinch roller from deforming.
⑥ Cut off the power of the machine, turn off the water source, pay attention to safety and save energy.
⑦ Take out the circuit control board in the electrical box and store it in a ventilated and dry place to prevent it from being affected by moisture.
⑧ If all the looms in a workshop need to be stopped, the main power supply and the main water source should be cut off, and the situation should be checked regularly by ventilation and moisture removal, and the workshop should be ventilated and dry.

2. The main work and precautions when the loom is turned on

①Open the main water supply pipeline before starting the machine, and drain the water first to prevent the residual sewage in the pipeline from entering the water tank, pump body and nozzles.
②Wet the warp yarns at the weaving mouth, reed and heddle with water to soften the remaining slurry, and avoid the hard pulp lump remaining when driving directly to pull the warp yarns and break them.
③Turn on the power supply, plug in the line control board, turn on the water tank water supply valve, test power and water, and observe whether the water and electricity are normal. 
④ Adjust the warp tension, and turn the spindle dial by hand to check whether the jetting, beating-up, hedging, etc. are normal.
⑤If you need to change the types and specifications of the raw silk, you can change the weft and the appropriate warp let-off and take-up gears to change the weft density.
⑥ If the reed healds are severely dropped, causing the warp to fluff, etc., manually shake the warp through the weaving opening by a few centimeters to ten centimeters, and try driving again depending on the actual situation.
⑦If the above main work is done well, after checking that everything is normal, you can start the operation according to the normal procedure.
