Abstract
The utility model relates to a novel seal of a compressor. The compressor comprises a compressor body. A piston rod is connected with a piston, and the piston is sealed with an air cylinder. The novel seal of the compressor is characterized in that a U-shaped groove is formed in the middle of each pitch of the piston, and the width d1 of each U-shaped groove is 1/3-2/3 of the distance between each adjacent pitches of the piston. The novel seal of the compressor has the advantages of simple structure and low improved cost and is suitable for promotion. The volume flow of product is hardly influenced by discharge pressure, and the sealing performance is improved. Meanwhile, the seal is not insensitive to contamination particles mixed in a compressed medium, the reliability is high, and the power balance is good.
Description
Technical field
The utility model belongs to Compressor Manufacturing field, is specifically related to the novel seal of compressor.
Background technique
Labyrinth compressor utilizes piston and cylinder to form sealing, under special operation condition, in compressed media, sneak into impurity particle time, will affect the working stability of compressor.
Model utility content
The purpose of this utility model is to provide the novel seal of compressor, and it is simple and reasonable for structure.
The technical solution of the utility model is: the novel seal of compressor, comprise compressor body, and piston rod is connected with piston, described piston and described cylinder seal; It is characterized in that: the intermediate portion at each pitch of described piston is provided with " U " type groove.
Further, each pitch that the width d1 of described " U " type groove is described piston is from 1/3-2/3 of d.
Further, each pitch that the width d1 of described " U " type groove is described piston is from 1/2 of d.
Beneficial effect: the utility model is simple in structure, and improvement expenses is cheap, suitable popularization; The volume flow of product is subject to the impact of exhaust pressure hardly, has improved sealability; Simultaneously insensitive to the impurity particle of sneaking in compressed media, reliability is high, and dynamical balancing is good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
This utility model of Fig. 2 embodiment's overall structure figure.
Fig. 3 is the partial enlarged drawing of Fig. 1;
In figure 1, piston, 2, cylinder, 3, piston rod, 4, " U " type groove.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the novel seal of compressor, comprises compressor body, and piston rod 3 is connected with piston 1, and described piston 1 forms sealing with described cylinder 2; Intermediate portion at each pitch of described piston 1 is provided with " U " type groove 4.
The width d1 of described " U " type groove 4 is that each pitch of described piston 1 is from 1/3-2/3 of d.
Beneficial effect: the utility model is simple in structure, and improvement expenses is cheap, suitable popularization; The volume flow of product is subject to the impact of exhaust pressure hardly, has improved sealability; Simultaneously insensitive to the impurity particle of sneaking in compressed media, reliability is high, and dynamical balancing is good.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all mode of executions.And these belong to apparent variation or the variation that connotation of the present utility model extends out and still belong to protection domain of the present utility model.
