Abstract
The present invention relates to a kind of polyimide coiled sleeve and processing method thereof, this sleeve pipe is with the one side coating multilayer polyimide winding film of polytetrafluoroethylene and the sleeve pipe of high-temperature shaping.The processing method of this polyimide coiled sleeve is: apply the multilayer polyimide winding film of polytetrafluoroethylene on the excellent core of certain diameter with one side, through high temperature process sizing, polyimide film is bonded together, takes out excellent core and namely form coiled sleeve.The present invention is that a kind of structure is simple, easy to manufacture, cost is low, is applicable to protective casing and the processing method thereof of refrigeration compressor motor use; this protective casing is soft, high temperature resistant and tube wall is very thin; the operational environment of refrigeration compressor motor can be born; meet instructions for use, play the effect of protective paint envelope curve and wire harness.
Description
Technical field
The present invention relates to motor enamel-covered wire outer tube field, especially polyimide coiled sleeve and processing method thereof.
Background technology
For ensureing the fail safe of motor, the enamelled wire of a part of refrigeration compressor motor between winding and binding post overlapping tubing, to improve the insulation property of enamelled wire, and preventing the enamelled coating because of enamelled wire from damaging and causing winding to scrap even motor scrapping.High-power refrigeration compressor motor requires to overlap tubing outside lead wire bundle simultaneously, plays protection wire harness in processing and use procedure not by mechanical damages such as generation scraped finish damages.
The sleeve pipe of current suit enamelled wire is glass braid sleeve pipe and teflon sleeve two kinds, and wherein glass braid sleeve pipe is glass braid and dip-coating organosilicon coating forms, and this sleeve pipe can not use in the workplace of refrigeration compressor motor.The cost of teflon sleeve is high, and hardness is also high, and due to the reason of material property cannot by the wall thickness reduction of sleeve pipe, so, although its workplace that can be used in refrigeration compressor motor uses, from the viewpoint of cost, serviceability all inconveniences.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, manufacture easy, easy to use, tube wall is thin and soft durable polyimide coiled sleeve and processing method thereof.
The object of the invention is to be realized by following technological means:
A kind of polyimide coiled sleeve, is characterized in that: this sleeve pipe is multilayer polyimide winding film with one side coating polytetrafluoroethylene and the sleeve pipe of high-temperature shaping.
A kind of processing method of polyimide coiled sleeve, it is characterized in that: apply the multilayer polyimide winding film of polytetrafluoroethylene on the excellent core of certain diameter with one side, adhesive property after utilizing polytetrafluoroethylene at high temperature happy and harmonious after winding and polyimides at high temperature still can keep the characteristic of dimensionally stable, through high temperature process sizing, polyimide film is bonded together, take out excellent core and namely form coiled sleeve.
Advantage of the present invention and good effect are:
1, this protective casing is with the one side coating multilayer polyimide winding film of polytetrafluoroethylene and the sleeve pipe of high-temperature shaping; because polyimides has good physical and mechanical properties; therefore this sleeve pipe has good physical and mechanical properties equally; can the mechanical damages such as scraped finish be tolerated, play the effect of protective paint envelope curve and wire harness.
2, the polytetrafluoroethylene used due to this protective casing, polyimide film are all be applicable to the material that refrigerant compressor uses, so this sleeve pipe can bear the operational environment of refrigeration compressor motor.In addition, because polyimides can steady in a long-term work, so this sleeve pipe can reach the instructions for use of 180 DEG C of (H) level motors under the condition of 200 DEG C.
3, this protective casing by wall thickness control at below 0.25mm, so whole sleeve pipe is very soft, can be highly suitable in the narrow and small motor of installing space and uses.
4, this protective casing processing method simple and flexible, can adjust the internal diameter of this sleeve pipe, thus make this sleeve pipe both may be used for the winding protection of refrigeration compressor motor, also may be used for wire harness protection according to the difference of product applicable situation.
5, the present invention is that a kind of structure is simple, easy to manufacture, cost is low, is applicable to protective casing and the processing method thereof of refrigeration compressor motor use; this protective casing is soft, high temperature resistant and tube wall is very thin; the operational environment of refrigeration compressor motor can be born; meet instructions for use, play the effect of protective paint envelope curve and wire harness.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the right view of Fig. 1.
Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
A kind of polyimide coiled sleeve, this sleeve pipe is with the one side coating multilayer polyimide winding film of polytetrafluoroethylene and the sleeve pipe 1 of high-temperature shaping.
The processing method of this polyimide coiled sleeve is: apply the multilayer polyimide winding film of polytetrafluoroethylene on the excellent core of certain diameter with one side, adhesive property after utilizing polytetrafluoroethylene at high temperature happy and harmonious after winding and polyimides at high temperature still can keep the characteristic of dimensionally stable, through high temperature process sizing, polyimide film is bonded together, take out excellent core and namely form coiled sleeve.
