Instructions
1. Installation instruction
2. Working principle of nozzle
1. natural yarn 2. interwoven yarn 3. yarn channel 4. air inlet
3. Nozzle structure
3-1 1. Shell 2. Nozzle core 3. Pressing plate 4. slide bar 5. thread guide
3-2 Installation of nozzle
3-2-1 Replacement of nozzle core
Notes: ensure the air source is closed before replacement.
Dismounting:
——Open the nozzle
——Insert the eccentric spoon horizontally
——90° upward rotation, to elevate the pressing plate
——remove the nozzle core forward
Assembling
一一Keep the eccentric spoon upright
——Push in the nozzle core
——Rotate the eccentric spoon down
——Close the nozzle
3-2-2 Replacement of pressing plate
Exerting forces on the pressing plate after removing the nozzle core.
3-2-3 Installation of nozzle core
4．Application in elasticizer
4-1 Compressed air requirement
Pressure fluctuation ±0.16ar; temperature 25℃±5℃, relative humidity ＜40％; residual oil＜0.2ppm.
4-2 Installation on elasticizer
Sliding nozzle should be installed between heater and 3 roller.
4-3 Left open and right open type
4-4 Yarn correction routes
5. Silk processing
5-1 Making up
5-2 Parameter determination
Deceleration between the third segment and the second segment depends on model and type of elasticizer.
5-3 Air pressure
To determine air pressure according to different technological conditions, such as silk denier, filament dinier, processing speed, thread guide and silk tension, etc.
5-4 Air consumption
Technical parameters:
F=0.4648×d2 qvn air consumption under standard conditions (m3/h)
*DINl343/Tn=273.15K(0℃)
*1M2=1.293kg dry air
*Pn=1.01325 bar (760rnmHg)
Pe＝air pressure of nozzle (bar)
