Abstract
The invention discloses a compressor rotor shaft sealing device which comprises a cylindrical nut cylinder body, wherein thread grooves are formed in the inner wall of the nut cylinder body; an annular inwards folded sealing ring is arranged at the top of the nut cylinder body; and an outwards bulged sealing cambered surface is arranged on the inner wall of the sealing ring. The compressor rotor shaft sealing device has the advantages that during use, a user directly fixes shaft sealing nuts to the two ends of a rotor of a compressor and puts sealing washers into the sealing rings. Under the action of the outwards bulged sealing cambered surface, the sealing ring deforms and then directly clings to the sealing cambered surface, so that the sealability of the rotor of the compressor is improved greatly, and the compressor rotor shaft sealing device is simple in structure, obvious in effect and high in practicability.
Description
Technical field
The present invention relates to a kind of Parts of Compressor, or rather, is a kind of compressor drum gland seal device.
Background technique
Compressor is requisite power source in refrigeration system, usually comprises a pair rotor in relative rotation.In order to improve the sealing of rotor, be equipped with shaft seal at the two ends of rotor.Existing shaft seal adopts the seal ring of quality of rubber materials usually, and this seal ring is easily subjected to displacement, and causes bearing sealing failure.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of compressor drum gland seal device.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of compressor drum gland seal device, described compressor drum gland seal device comprises the nut cylindrical shell of a cylindrical shape, the inwall of described nut cylindrical shell is provided with thread groove, the top of described nut cylindrical shell is provided with the seal ring of the fold inward of an annular, and the inwall of described seal ring is provided with an outwardly sealing cambered surface.
As preferred embodiment of the present invention, described compressor drum gland seal device is that stainless steel is one-body molded.
The advantage of compressor drum gland seal device of the present invention is: during use, and this shaft seal nut is directly fixed to the two ends of the rotor of compressor by user, and is placed in seal ring by seal washer.Under the effect of outwardly sealing cambered surface, directly touch sealing cambered surface, substantially increase the sealability of compressor drum after seal ring generation deformation, structure is simple, and successful is practical.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of compressor drum gland seal device of the present invention;
Fig. 2 is the perspective view of the compressor drum gland seal device in Fig. 1, is now another visual angle;
Fig. 3 is the sectional view of the compressor drum gland seal device in Fig. 2 along A-A line;
Fig. 4 is the details enlarged diagram in the B region of compressor drum gland seal device in Fig. 3;
Wherein,
1, compressor drum gland seal device; 2, nut cylindrical shell; 3, seal ring; 4, thread groove; 5, cambered surface is sealed.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
As shown in Figures 1 to 4, this compressor drum gland seal device 1 comprises the nut cylindrical shell 2 of a cylindrical shape, the inwall of this nut cylindrical shell 2 is provided with thread groove 4, the top of this nut cylindrical shell 2 is provided with the seal ring 3 of the fold inward of an annular, and the inwall of sealing ring 3 is provided with an outwardly sealing cambered surface 5.
This compressor drum gland seal device 1 is that stainless steel is one-body molded.
During use, as depicted in figs. 1 and 2, this shaft seal nut 1 is directly fixed to the two ends of the rotor of compressor by user, and is placed in seal ring 3 by seal washer.Under the effect of outwardly sealing cambered surface 5, directly touch sealing cambered surface 5 after seal ring generation deformation, substantially increase the sealability of compressor drum, structure is simple, and successful is practical.
Be not limited to this, any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
