Three layers of combined dry, dry and crosslinked cable production lines.
(1) water vapor process parking procedure,
Stop the crosslinking tube heating power and remove the heating sleeve on the expansion pipe.
Pull each extruder separately and remove the inner shield.
Adjust the water level to the highest control.
Stop the nitrogen, reduce the speed of the extruder, reduce the outer diameter of the cable, so as to pass the sealing machine, and complete the full stop when the nitrogen is finished.
When the pressure in the tube is zero, turn on the interlocking device and the upper closure.
6, make the finished product mark, take plastic waste line out of the line,
After the full line stop, stop the pump, put off the cooling water.
The extruder shall be cleaned according to the regulations.
Turn off all switches, valves.
(2) electric process parking procedure
Turn off the heat source and remove the heating sleeve from the expansion pipe.
Take the nitrogen cycle, cool the heating section and the cable, and stop the nitrogen cycle.
3, the extruder slows down to make the cable pass down the retainer.
4, when the crosslinking tube indicate the temperature dropped to below 150 ℃, stop the systemic circulation, supply of nitrogen, and nitrogen gas discharge tube.
When nitrogen discharge, the extruder stops feeding.
When the pressure is zero, turn on and off
7, the plastic in the core of the wire, which leads the conductor to the crosslink.
Other methods of processing and water vapor process.
