Abstract
The invention discloses a suction pipe component of a rotary compressor, which comprises a rounding-off and step-shaped suction pipe and an air cylinder, into which the suction pipe is inserted. An annular groove is arranged on the edge of the suction pipe part which is inserted into the air cylinder and close to the exterior of the air cylinder; an elastic sealing ring is placed in the groove; a matched annular groove is arranged on the air cylinder and positioned in the position corresponding to the elastic sealing ring when the suction pipe is inserted; and the elastic sealing ring is just closely filled in the matched annular groove. The suction pipe component has the beneficial effects that the elastic sealing ring is arranged on the suction pipe, thereby structurally avoiding leakage between the air cylinder and the suction pipe, and improving the product performance.
Description
Technical field
The present invention relates to rotary compressor, especially the suction conduit assembly of rotary compressor.
Background technique
As shown in Figure 1, traditional closed rotary compressor, the upside in seal container 10 inside of compressor 1 is equipped with motor part 20, is keeping at a certain distance away with motor part 20, near downside compressor section 30 is installed.Motor part 20 comprises the stator 21 that produces magnetic force according to the power supply that applies; Rotor rotated 22 is pressed into the running shaft 23 that rotating force is transmitted at the center that is fixed on rotor 22 because the magnetic force of stator 21 forms the variation of magnetic flux.Compressor section 30 comprises that the refrigerant that will suck compresses the cylinder 31 of discharging afterwards and being provided with; Be assembled in the top and the bottom of cylinder 31, and in cylinder, form pressing chamber P; Be connected with running shaft 23 respectively, and the upper bearing 32 of supporting rotating shaft and lower bearing 33.
In the pressing chamber P inboard of cylinder 31, be provided with the eccentric cam 24 that has eccentric part 25 with the eccentric certain distance in axle center of running shaft 23.Contact inserts on the outer circumferential face of eccentric cam 24, and the annular piston 34 that revolves round the sun of the rotating force that transmits according to eccentric cam 24.
Among the figure, the 42nd, the refrigerant tap hole of upper bearing, the 43rd, exhaust valve assembly, the 44th, baffler, the 45th, refrigerant suction pipe, the 46th, refrigerant discharge tube.
As shown in Figure 2, the sucking pipe 45 of traditional rotary compressor, for having the smooth copper pipe of slick and sly stair-stepping outer wall, sucking pipe 45 directly is inserted in the cylinder 31 combines closely, but, this structure, just guaranteeing precision conjugation by processing, exist sucking pipe to cooperate defective tightness, might produce the problem of gas leakage with cylinder.
Summary of the invention
Technical problem to be solved by this invention is: a kind of suction conduit assembly that prevents the rotary compressor that leaks gas between cylinder and the sucking pipe is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of suction conduit assembly of rotary compressor, comprise the stair-stepping sucking pipe of rounding off and the cylinder of insertion sucking pipe, suction pipe part in being inserted into cylinder has annular groove near the external margin of cylinder; Be placed with elastic seal ring in the groove; Cylinder is provided with the cooperation annular groove, the position of elastic seal ring correspondence when cooperating annular groove to be positioned at the sucking pipe insertion, and elastic seal ring just in time closely is filled in the cooperation annular groove.
Described elastic seal ring is higher than the sucking pipe external diameter 0.1～1mm of groove.
Described elastic seal ring is resistant to elevated temperatures rubber material.
The invention has the beneficial effects as follows: owing on sucking pipe, be provided with elastic seal ring, structurally prevented to leak gas between cylinder and the sucking pipe, improved the performance of product.
Description of drawings
Fig. 1 is traditional rotary compressor sectional arrangement drawing.
Fig. 2 is the suction conduit assembly sectional drawing of traditional rotary compressor.
Fig. 3 is the suction conduit assembly sectional drawing of rotary compressor of the present invention.
Embodiment
Be described in further detail below in conjunction with the sucking pipe structure of the drawings and specific embodiments rotary compressor of the present invention:
The working principle of rotary compressor of the present invention is identical with prior art, can be with reference to prior art, so no longer narration, the difference of the present invention and prior art is the sucking pipe structure of rotary compressor, is described in detail below:
As shown in Figure 3, the suction conduit assembly of rotary compressor of the present invention comprises the stair-stepping sucking pipe 5 of rounding off and inserts the cylinder 2 of sucking pipe 5, and suction pipe 5 parts in being inserted into cylinder 22 have annular groove 3 near the external margin of cylinder 2; Be placed with elastic seal ring 4 in the groove 3; Cylinder 2 is provided with and cooperates annular groove 6, the position of elastic seal ring 4 correspondences when cooperating annular groove 6 to be positioned at sucking pipe 5 insertions, and elastic seal ring 4 just in time closely is filled in the cooperation annular groove 6.
Described elastic seal ring 4 is higher than the sucking pipe 5 external diameters 0.1～1mm at groove 3 places, is resistant to elevated temperatures rubber material.
The present invention is owing to be provided with elastic seal ring on sucking pipe, the external diameter of elastic seal ring is higher than the external diameter of sucking pipe, is to have prevented to leak gas between cylinder and the sucking pipe from structure, improves the performance of product.
In sum, among the embodiment that content of the present invention is not confined to, the knowledgeable people in the same area can propose other embodiment easily within technological guidance's thought of the present invention, but this embodiment comprises within the scope of the present invention.
