Abstract
The utility model relates to a protective sleeve for an F-grade refrigeration compressor motor winding, comprising a wound sleeve and a braided layer, wherein the braided layer coaxially wraps the outer surface of the wound sleeve, and the braided layer is a ploynaphthyl fiber braided layer. The protective sleeve is simple in structure, easy in manufacture, reliable in use, and low in cost, and is suitable to be used in a motor with a small mounting space, and the composite protective sleeve is formed by a wound sleeve and a ploynaphthyl fiber braided layer, can be used in the working environment of the refrigeration compressor motor, and can achieve the F-grade insulating demand.
Description
Technical field
The utility model relates to the outer tube field of enamelled wire, especially a kind of F level refrigeration compressor motor winding protection sleeve pipe.
Background technology
Be to guarantee the fail safe of motor, a part of motor overlaps tubing on the enamelled wire between winding and the binding post, improving the insulation property of enamelled wire, and prevents that enamelled coating because of enamelled wire from damaging and causes winding to be scrapped even motor is scrapped.
At present the sleeve pipe of suit enamelled wire is glass braid sleeve pipe and two kinds of teflon sleeves, and wherein the glass braid sleeve pipe is that glass braid and dip-coating organosilicon coating form, and this sleeve pipe can not be in the use of the workplace of refrigeration compressor motor.The cost of teflon sleeve is high, and hardness is also high, and owing to the reason of material property can't be with the wall thickness reduction of sleeve pipe, so, though use its workplace that can be used in refrigeration compressor motor, consider all inconvenient from cost, serviceability aspect.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of reasonable in design, cost is low, tube wall is thin, insulation effect is good F level refrigeration compressor motor winding protection sleeve pipe is provided.
The purpose of the utility model realizes through following technological means:
A kind of F level refrigeration compressor motor winding protection sleeve pipe is characterized in that: comprise coiling sleeve pipe and braid, the coaxial outer surface that is wrapped in the coiling sleeve pipe of braid, this braid are to gather naphthalene ester fiber braid.
And described coiling sleeve pipe is to gather the sleeve pipe that the naphthalene ester film is reeled and high-temperature shaping forms with the multilayer that single face applies high temperature resistant glue.
And described braid is bonded in the outer surface of coiling sleeve pipe.
The advantage and the good effect of the utility model are:
1, the utility model is that an inside is the coiling sleeve pipe; The cover tube outside weaves the composite bushing that forms with gathering the naphthalene ester fiber reeling; Because the internal layer of sleeve pipe is the coiling sleeve pipe, when threading, pass through easily, and the braid of outside has good pliability; Can play the effect of protection coiling sleeve pipe and enamelled wire wherein, thus overcome single laminate roll around the defective of sleeve pipe or individual layer braided sleeving, prolonged useful life of enamelled wire and motor.
2, because the employed high temperature resistant glue of this composite bushing, to gather the naphthalene ester film and gather the naphthalene ester fiber all be the material that is applicable to that refrigerant compressor uses; And can be for a long time 155 ℃ of work down; So this sleeve pipe can bear the operational environment of refrigeration compressor motor, can reach the requirement of F class F insulation.
3, this composite bushing can be controlled at wall thickness below the 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, braid of this composite bushing and coiling sleeve pipe bond together earnestly adding man-hour, thereby have effectively avoided the possibility of braid and the layering of coiling sleeve pipe, and the possibility of also having avoided braid to scatter has simultaneously guaranteed serviceability.
5, the utility model be a kind of simple in structure, easy to manufacture, use reliable, cost is low, be adapted at the F level refrigeration compressor motor winding protection sleeve pipe that uses in the narrow and small motor of installing space; This composite protective sleeve by the coiling sleeve pipe with gather naphthalene ester fiber braid and constitute; The operational environment that it can bear refrigeration compressor motor reaches the requirement of F class F insulation.

Embodiment
Be described in detail the embodiment of the utility model below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit the protection range of the utility model with this.
A kind of F level refrigeration compressor motor winding protection sleeve pipe comprises coiling sleeve pipe 1 and braid 2, the coaxial outer surface that is wrapped in the coiling sleeve pipe of braid.Coiling sleeve pipe in the present embodiment is to gather the sleeve pipe that the naphthalene ester film is reeled and high-temperature shaping forms with the multilayer that single face applies high temperature resistant glue, and braid is to gather naphthalene ester fiber braid, and this braid is bonded in the outer surface of coiling sleeve pipe through fervent processing.
The course of processing of the utility model is:
The multilayer that the effective single face of cover of reeling applies high temperature resistant glue is gathered the excellent core that the naphthalene ester film is wound on certain diameter and is formed, and makes through high temperature process behind the coiling and gathers the naphthalene ester film and bond together, and takes out excellent core and forms sleeve pipe; The coiling sleeve pipe machines the back and weaves with gathering the naphthalene ester fiber in its outside; Braiding is cut into specific length with fervent mode with protective casing after accomplishing, and the coiling sleeve pipe of braid and the inside bonds together in the time of earnestly.
