Technical field
The present invention relates to a kind of three-layer co-extruded insulated cable production method and production system thereof, belong to electrical equipment technical field.
Background technology
Three layer insulation wire is a kind of High Performance Insulation wire, and this wire has three insulating barriers, and centre is heart yearn.Traditional three layer insulation wire from inside to outside ground floor is transparent glass layer, the second layer is the varnished of high-insulativity, and the 3rd layer is to be flavous polyamide film, and its thickness is several microns, but can bear the high voltage pulse of 3kV, the gross thickness of insulating barrier is only 20 ~ 100um.
Traditional three layer insulation wire, three layers complete again and again.Had the three-layer co-extruded equipment that goes out abroad, but price is quite expensive, the equipment of domestic substantially all three layer insulation wire producers is all that one deck is produced, and then does the second layer, and then does the 3rd layer, low, the power consumption of equipment service efficiency like this, waste of manpower.
Summary of the invention
The object of the invention is to solve the higher problem of technical sophistication, cost of three insulating barrier coextrusion molds of cable in prior art, provide a kind of three-layer co-extruded insulated cable production method and production system thereof to solve the problems referred to above.
To achieve these goals, technical scheme of the present invention is as follows:
A production method for three-layer co-extruded insulated cable, comprises the steps:
A, cable core is wrapped on active actinobacillus frame;
B, startup active actinobacillus frame, be delivered to cable core in preheater, at 90 ~ 120 ℃, carries out preheating;
C, the cable core after preheating is delivered in the first extrusion main unit, the second extrusion main unit and the 3rd extrusion main unit successively, plates successively from inside to outside successively the first insulating barrier, the second insulating barrier and the 3rd insulating barrier;
D, by the cable that plates the 3rd insulating barrier defeated deliver to successively movable warm water tank and fixedly tank carry out cooling and shaping in total;
E, by sizing after cable by log, two-wheeled hauling machine, meter-measuring device, be delivered on storage rack;
F, the cable on storage rack is delivered to and in double-shaft wire winder, is wound around rolling;
Wherein, described the 3rd insulating barrier is polyamide layer.
In the present invention, it is 180 ~ 220m/min that the speed of service of described heart yearn in production system controlled.
In the present invention, the water temperature in described movable warm water tank is 60 ~ 80 ℃, and the water temperature in described fixedly tank is normal temperature.
For a production system for production method of the present invention, comprise setting gradually: active actinobacillus frame, preheater, the first extrusion main unit, the second extrusion main unit, the 3rd extrusion main unit, movable warm water tank, fixedly tank, log, two-wheeled hauling machine, meter-measuring device and double-shaft wire winder.
In the present invention, this production system also comprises storage rack, and described storage rack is arranged on movable warm water tank, the fixing top of tank, log, two-wheeled hauling machine.
In the present invention, described movable warm water tank is provided with master control electronic box.
In the present invention, described meter-measuring device is provided with spark machine.
It is quite expensive that abroad three-layer co-extruded goes out equipment, and the equipment of domestic substantially all three layer insulation wire producers is all that one deck is produced, and then does the second layer, and then does the 3rd layer.This process and technology innovation is exactly to increase and extrude on common individual layer extrusion equipment, is the insulation technology completing for three times, in once producing, completes.Core technology shows:
The first, this process modification key technology is material property modification.This designing material formula is a systematic procedure.From present experiment with through examining, meet present customer requirement and designing requirement out of question.To further improve qualification rate aspect, also will do a large amount of work, select the material of better coupling.
The second, scrap build, the equipment operating idea of core is in ripe operation of other field; Meticulously select suitable equipment vendor to unify coordinately rebuild equipment, this point designs basically identical by experiment and originally; Difficult point is the unified electrical control of equipment, substantially adopts now single action, and this needs skilled high-quality operating personnel, and this point also needs the exercise of time and the break-in of personnel and equipment.
Three, well-designed, the in good time quality monitoring of production of technique, worker at the production line's process implementing is crucial, and this point will at every moment be held inspection.
Beneficial effect of the present invention is mainly reflected in: mechanical performance and the electric property of cable increase; Primary Calculation and actual verification can saves energy 40%, and operating personnel reduce 50%, and efficiency improves 60%, economic benefit suitable obviously.
