Description
Affiliated technical field
The utility model relates to a kind of air suction silencer that is applied to hermetically sealed compressor.。
Background technique
Air suction silencer is widely used in hermetically sealed compressor, general employing heat-insulating property plastic materials is preferably made, being in order to reduce noise on the one hand, is in order to reduce the heat effect of compressor heat to refrigeration agent, to improve the gettering efficiency of compressor on the other hand.Existing air suction silencer is made up of loam cake, suction conduit assembly and lower casing usually, and the loam cake of air suction silencer and lower casing assembling back form anechoic chamber's cavity, two chambers about the dividing plate of suction conduit assembly is divided into anechoic chamber's cavity.Be the effect of guaranteeing that air suction silencer reduces noise, raises the efficiency, the assembling of loam cake and lower casing needs very high seal request.Three kinds of sealing assembly methods are arranged at present, and first kind of employing compresses sealing means, adopt this air suction silencer cost that compresses mode lower, but the place of compressing is easy to generate leakage, and sealing effect is bad; Second kind is adopted the welded seal mode, can avoid leaking, and good sealing effect, but manufacturing process complexity, cost is higher; The third adopts the injection moulding sealing means, also can avoid leaking, and good sealing effect, but manufacture cost is higher equally.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of and makes simply, cost is low, the compressor of good sealing effect sealing air suction silencer.
For solving the problems of the technologies described above, the utility model suction muffler for compressor comprises loam cake, sealing gasket, suction conduit assembly and lower casing, cover on described and be provided with loam cake sucking pipe and loam cake seal face, described lower casing is provided with lower casing intakeport, lower casing sucking pipe and lower casing seal face, described sealing gasket is provided with positioning hole, and described lower casing intakeport, lower casing sucking pipe, suction conduit assembly and loam cake sucking pipe are formed the air-breathing path of refrigeration agent.
The above-mentioned compressor air suction silencer, described suction conduit assembly is made up of two and half sucking pipes, and that its shape is made as is L shaped, U-shaped, W shape and S shape etc.
Above-mentioned compressor air suction silencer, described suction conduit assembly are provided with projection and compress the inwall of described lower casing.
Above-mentioned compressor air suction silencer, described sealing gasket are located between loam cake seal face and the lower casing seal face.
The utility model is owing to adopted technique scheme, it utilizes loam cake seal face and lower casing seal face after assembling the impacting force that sealing gasket produces to be reached sealing effect, by adjusting the mounting structure and the design parameter of loam cake and lower casing, and select the suitable seal cushion material, avoid the effect leaking, reduce noise and raise the efficiency thereby reach.Through test comparison, adopt air suction silencer of the present utility model, the compressor overall noise reduces about 2dB, and the complete machine performance improves more than 1%.

Embodiment
As shown in Figure 1, hermetically sealed compressor is formed the sealing steel shell by upper shell 1 and lower shell body 7, inside comprises the electric component that mechanical part that crankcase 3, cylinder head 2 etc. form and motor stator 6 etc. are formed, motor stator 6 wherein is fixed on the crankcase 3, the external structure of air suction silencer comprises loam cake 4, lower casing 5 and lower casing intakeport 8, and loam cake sucking pipe 9 closely is fixed on the valve plate suction port place in the cylinder head 2.
Be illustrated in figure 2 as the air suction silencer after the assembling, loam cake 4, lower casing 5 are by hasp 10, lug 11 fastenings.For guaranteeing the fastening effect, the hasp 10 that loam cake 4 is arranged more than 4, the lug 11 that lower casing 5 is arranged more than 4.
As shown in Figure 3, air suction silencer is made up of loam cake 4, sealing gasket 13, suction conduit assembly 14 and lower casing 5 etc., and wherein suction conduit assembly 14 is formed (as shown in Figure 4) by half sucking pipe 17, half sucking pipe 19.Air suction silencer inside is divided into left anechoic chamber 12 and right anechoic chamber 16, and the by-pass port 18 of suction conduit assembly 14 and anechoic chamber, the left and right sides connect, and the intakeport 8 of suction conduit assembly 14 is aimed at lower casing sucking pipe 10.Lower casing sucking pipe 10, lower casing intakeport 8, suction conduit assembly 14 and loam cake sucking pipe 9 have been formed the air-breathing path of refrigeration agent.The positioning hole of the sealing gasket 13 loam cake sucking pipe 9 of packing into, the seal face of loam cake 4 and lower casing 5 compresses sealing gasket 13.The sucking pipe 9 of loam cake 4 can enter the step hole of suction conduit assembly 14.
As shown in Figure 5, dividing plate 21 on the suction conduit assembly 14 and dividing plate 23 are divided into left anechoic chamber 12 and right anechoic chamber 16 with baffler inside.Projection 22 and projection 24 on the suction conduit assembly 14 compress the inwall of lower casing 5, thereby guarantee suction conduit assembly 14 mounting stability.
As shown in Figure 6, suction conduit assembly 14 is made up of half sucking pipe 17, half sucking pipe 19.The assembling mode of half sucking pipe 17 and half sucking pipe 19 can obtain comparatively complicated pipelines shape (as L shaped, U-shaped, S shape, W shape etc.).
As shown in Figure 7, suction conduit assembly 14 is by dividing plate 21, dividing plate 23 and U-groove bevel 25 lower casing 5 of packing into, sealing gasket 13 is by the positioning hole 26 loam cake sucking pipe 9 of packing into, loam cake 4 and lower casing 5 are by hasp 10 and lug 11 fastenings, lower casing seal face 20 compresses sealing gasket 13, guarantees the sealability after loam cake 4 and lower casing 5 assemble.
The utility model air suction silencer uses in new and effective compressor in batches, and with common air suction silencer test comparison, gettering efficiency can reach equal even better level, and the compressor overall noise reduces about 2dB, and the complete machine performance improves more than 1%.
