Embodiment Construction

[0019] Such as figure 1 As shown, the fully enclosed refrigeration compressor is composed of an upper shell 1 and a lower shell 7. The closed steel shell is composed of mechanical components such as a crankcase 3 and a cylinder head 2, and electrical components such as a motor stator 6. Among them The motor stator 6 is fixed on the crankcase 3. The external structure of the suction muffler includes the upper cover 4, the lower shell 5 and the suction port 8, and the suction pipe 9 at the upper end is tightly fixed to the valve plate suction in the cylinder head 2. stomata.

[0020] Such as figure 2 Shown is the assembled suction muffler, the upper cover 4 and the lower shell 5 are fastened by the hasp 24 and the clasp 22 . In order to ensure fastening effect, more than 4 hasps 24 are arranged on the upper cover 4 , and more than 4 hasps 22 are arranged on the lower shell 5 .

[0021] Such as image 3 As shown, the suction muffler is made up of loam cake 4, filter screen 2...

Abstract

The invention discloses an intake silencer of compressor, which comprises an upper cover, an intake tube element and a lower frame. Wherein, the upper cover is mounted with intake tube; the lower frame is mounted with an air entry and an intake tube; the air entry, intake tube, intake tube element and the intake tube of upper cover form the intake path of coolant; the baffle on the intake tube element divides the chamber of silencer into left silence chamber and right silence chamber; the intake tube element of left silence chamber has two or more bypass ports. The invention, via adjusting and optimizing the intake path, the area of bypass ports and the filter screen, obtains better intake efficiency and silence effect, while the whole noise of compressor can be reduced 3dB.

Description

technical field [0001] The invention relates to a plastic suction muffler applied to a fully enclosed refrigeration compressor. Background technique [0002] Suction mufflers are used in hermetic refrigeration compressors, and are generally made of plastic materials with better thermal insulation performance. On the one hand, it is to reduce noise, and on the other hand, it is to reduce the heating effect of the compressor heat on the refrigerant and improve compression. The suction efficiency of the machine. The existing suction muffler usually has two sound-absorbing chambers and a suction pipeline. As compressor users have higher and higher requirements for noise reduction, in order to reduce noise, some suction mufflers use three or more sound-absorbing chambers to reduce noise, and some use the length of the entire suction line to reduce noise. To reduce noise, some use complex-shaped suction pipelines (such as S-shaped) to reduce noise, and some use reduced suction p...
