Three layers of combined dry and dry joint cable production line driving process:
(1) the line is adjusted so that it can be pulled down to the bottom of the line.
(2) the tension adjust speed according to the process shall be determined, wire tension by the traction control, suspension control is put into use, the feedback control role in traction, with traction on the synchronization, when the suspension controller instructions or not swing at zero, means that the tension.
The release of the disc will be up to the required position.
The line should be adjusted for tension and will be closed to the optimum condition.
(3) the extruder go first line start the program startup, then start the shielding extruder, when set to conform to the requirements of the process, with the consent of the under an extruder, can with shielding wire core into the next stage in extruder, and then start the insulation extrusion machine and outer shielding extruder respectively, when the thickness of each layer, eccentricity, adjusted the appearance quality and make the wire core into crosslinked with plastic tube, hanging cooling control device for the nitrogen, suspended by the controller
(4) when the water vapor process is used in the water vapor process, when the insulated line is entered into the crosslinking tube, the pump can be opened to allow the cooling water to enter the cooling section.
(5) sealing the sealing device when the wire core with plastic is out of the sealing, and sealing off the sealing device when it meets the process requirement.
(6) the crosslinking tube shall be heated by process regulation
(7) for nitrogen according to the procedures and regulations.
(8) when the temperature, the pressure meets the requirements, the seal shall be marked at the next closed place, and the finished product shall be followed by 60 meters, and the specimen shall be inspected.
(9) the finished product line is collected online, and the speed and line pitch are adjusted to normal production.
