Description
Technical field
The utility model relates to coaxial cable manufacturing technology field, particularly a kind of cooling system of making the large-diameter coaxial cable core.
Background technology
In recent years, the global system for mobile telecommunications technical development is swift and violent, and China's mobile communication technology means also develop into GSM, cdma system by analogue system gradually, and the construction of a large amount of mobile communication base stations makes the market demand of RF communication coaxial cable increasing.The heart yearn manufacturing is one of RF communication coaxial cable key manufacturing technology, and the production efficiency that how effectively to improve cable has become each producer's problem demanding prompt solution.Usually, the heart yearn manufacturing process of coaxial cable producer is after heart yearn is extruded through the insulation plastic extruding machine, to cool off again through the take-up stand take-up through the normal-temperature water tank; Because large-diameter coaxial cable core temperature when plastic extruding machine is extruded is very high and thick, from the high temperature heart yearn that comes out of insulation plastic extruding machine when tank is cooled to lower temperature, need make longer cooling effectiveness of the residence time of heart yearn in tank low, cause the heart yearn payingoff speed slower, and then production efficiency is reduced.
The utility model content
A purpose of the present utility model is in order to overcome the deficiency of existing cooling system, a kind of temperature that can reduce heart yearn fast to be provided, can accelerate the speed of production of heart yearn, improving the cooling system of heart yearn productivity effect.
This purpose of the present utility model is achieved by the following technical solution: a kind of coaxial cable core wire cooling system, it comprises the cooling water circulation loop that tank, water tank and water pump constitute, it is characterized in that, this system also includes cooling-water machine, this cooling-water machine is connected between tank and the water tank by pipeline, the water temperature of described cooling water is controlled in 0--18 ℃, does not comprise 0 ℃.
The water temperature of described cooling water is controlled in 10--18 ℃.
Periphery at described tank also is enclosed with heat-preservation cotton.
The utility model is in order to improve the production efficiency of large-diameter coaxial cable core, most critical be the cooling system that has improved the heart yearn bosh, cooling water is remained on rational steady temperature, can accelerate radiating rate, improve the speed of production of heart yearn, reduced the residence time of heart yearn, thereby improved the production efficiency of cable at tank.To tank parcel heat-preservation cotton, can reduce the generation of stainless steel trough condensed exterior water, reduce thermal loss.Prevent that simultaneously moisture from entering coaxial cable core wire inside, in order to avoid influence the electric property of coaxial cable.
Description of drawings
Fig. 1 is the coaxial cable core wire cooling system figure of the utility model embodiment one;
Fig. 2 is the coaxial cable core wire cooling system figure of the utility model embodiment two.
Embodiment
Below in conjunction with embodiment the utility model is further described.
Embodiment one
Referring to shown in Figure 1, be the utility model embodiment one coaxial cable heart yearn cooling system figure, this cooling system comprises the cooling water circulation loop of the tank, cooling-water machine, water tank and the water pump composition that connect successively.
Described tank is 70m for selecting flute length for use, and groove width is the stainless steel trough of 0.2m, and the periphery of tank is enclosed with the heat-preservation cotton that a layer thickness is 25mm, and heat-preservation cotton can play insulation effect, can prevent the generation of condensed water simultaneously.
Described cooling-water machine adopts 10 Cool-water Machine for Industry, in be provided with high-quality compressor, water pump and thermostat, the cold water function is controlled at 10--18 ℃ with the water temperature of cooling circulating water exactly; Simultaneously cooling-water machine also adopts preferable condenser of heat exchange effect and radiator, and be provided with current overload, anti-phase is owed and anti-icing protection, height compacting and electronic time delay safety device when breaking down, can send warning signal immediately, and show failure cause.
Described water tank is used for storing through the cooled cooling water of cooling-water machine, and it is 2m that this water tank adopts volume
3, the length of water tank, width, highly be 2m * 1m * 1m.Be furnished with spilling water control ball control water surface elevation in the water tank, water surface elevation is controlled at below the 80cm, can hold about 1.6m
3Recirculated cooling water.The peripheral stickup of water tank one layer thickness is the heat-preservation cotton of 25mm, plays insulation effect.
The power of described water pump is 1.5 kilowatts, and lift 20m, flow are 11.4m
3/ hour.The delivery port of water pump connects return flume with pipeline, behind the starting mode of pump, the cooling water in the water tank can be drawn back tank, realizes the cooling water circulation.
Embodiment two
As shown in Figure 2, the difference of present embodiment and embodiment one is, is on the basis of the cooling system of former embodiment one, increases by one by the cooling water circulation loop of tank through the direct reflow tank of piping.
The operation of whole system is as follows, normal-temperature water in the boiled water room is transported to water tank through feed tube, normal-temperature water in the water tank pumps to tank through water pump, some recirculated water is got back to water tank through channel flow in the tank, to the cooling-water machine cooling, get back to water tank through water-supply-pipe and store, and then pump return flume through water pump by cooled water through return pipe for a part, through recycling repeatedly, the temperature of circulation back cooling water is controlled at 10--18 ℃ like this.
Certainly, by the effect of described cooling-water machine, the water temperature of described cooling water can be controlled in 0--18 ℃.But because described heart yearn is from the insulation plastic extruding machine when extruding, be in molten condition,, can cause the foaming structure of insulating barrier to change big with the dielectric loss angle change if insulation foaming layer cooling is too fast, the loss value of coaxial cable is increased, influence the electric property of coaxial cable; And cross when low when water temperature, the generation of stainless steel trough condensed exterior water also can produce moisture in the workshop in the waste cold.In order to reduce thermal loss, prevent that moisture from entering coaxial cable core wire inside, in order to avoid influence the electric property of coaxial cable, therefore, the scope of the best of described cooling water is 10--18 ℃.
