Abstract
The invention relates to a protective sleeve for an F-level refrigerating compressor motor winding. The protective sleeve comprises a winding sleeve and a braided layer, wherein the braided layer is coaxially coated on an outer surface of the winding sleeve and is a polynaphthalene ester fiber braided layer. The protective sleeve for the F-level refrigerating compressor motor winding is simple in structure, easy to manufacture, reliable to use and suitable for a motor with small installation space and has low cost. The composite protective sleeve consists of a winding sleeve and a polynaphthalene ester fiber braided layer, a working environment of a refrigerating compressor motor can be born, and an F-level insulation requirement is met.
Description
Technical field
The present invention relates to the outer tube field of enamelled wire, especially a kind of F level Winding protecting sleeve for motor of refrigeration compressor.
Background technology
For ensureing the fail safe of motor, the enamelled wire of a part of 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.
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, a kind of reasonable in design, cost is low, tube wall is thin, insulation effect is good F level Winding protecting sleeve for motor of refrigeration compressor is provided.
The object of the invention is to be realized by following technological means:
A kind of F level Winding protecting sleeve for motor of refrigeration compressor, it is characterized in that: comprise coiled sleeve and braid, braid is coaxially wrapped in the outer surface of coiled sleeve, and this braid is poly-naphthalene ester fiber braid.
And described coiled sleeve gathers naphthalene ester film winding and the sleeve pipe of high-temperature shaping by the multilayer that one side applies high temperature resistant glue.
And described braid is bonded in the outer surface of coiled sleeve.
Advantage of the present invention and good effect are:
1, the present invention is an inside is coiled sleeve; with the composite bushing of poly-naphthalene ester fiber braiding outside coiled sleeve; internal layer due to sleeve pipe is coiled sleeve; easily pass through when threading; and the braid of outside has good pliability; protection coiled sleeve and the effect of enamelled wire wherein can be played, thus overcome the defect of individual layer coiled sleeve or single layer knitted sleeve, extend the useful life of enamelled wire and motor.
2, the high temperature resistant glue, poly-naphthalene ester film and the poly-naphthalene ester fiber that use due to this composite bushing are all the materials being applicable to refrigerant compressor use, and can work at 155 DEG C for a long time, so this sleeve pipe can bear the operational environment of refrigeration compressor motor, the requirement of F class F insulation can be reached.
3, this composite bushing can by wall thickness control at below 0.25mm, and its woven outer layer is very soft simultaneously, so whole sleeve pipe is very soft, is adapted at using in the narrow and small motor of the such installing space of refrigeration compressor motor.
4, the braid of this composite bushing and coiled sleeve bond together earnestly adding man-hour, thus effectively prevent the possibility of braid and coiled sleeve layering, it also avoid the possibility that braid scatters simultaneously, ensure that serviceability.
5, the present invention be a kind of structure simple, easy to manufacture, use reliable, cost is low, be adapted at the F level Winding protecting sleeve for motor of refrigeration compressor that uses in the narrow and small motor of installing space; this composite protective sleeve is made up of coiled sleeve and poly-naphthalene ester fiber braid; it can bear the operational environment of refrigeration compressor motor, reaches the requirement of F class F insulation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the left 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 F level Winding protecting sleeve for motor of refrigeration compressor, comprise coiled sleeve 1 and braid 2, braid is coaxially wrapped in the outer surface of coiled sleeve.Coiled sleeve in the present embodiment gathers naphthalene ester film winding and the sleeve pipe of high-temperature shaping by the multilayer that one side applies high temperature resistant glue, and braid is poly-naphthalene ester fiber braid, and this braid is bonded in the outer surface of coiled sleeve by fervent processing.
The course of processing of the present invention is:
The multilayer that coiled sleeve one side applies high temperature resistant glue is gathered the excellent core that naphthalene ester film is wound on certain diameter and is formed, and through high temperature process, poly-naphthalene ester film is bonded together, take out excellent core and form sleeve pipe after winding; Weave with poly-naphthalene ester fiber outside it after coiled sleeve machines; Protective casing is cut into specific length by the mode having woven rear use fervent, and time fervent, the coiled sleeve of braid and the inside bonds together.
