Abstract

The application discloses rotor compressor's double-deck shell structure, a serial communication port, the compressor includes double-deck shell, and double-deck shell is equipped with shell body and interior casing, establishes to the filling layer between shell body and the interior casing, packs sound absorbing material in the filling layer. When the compressor runs, the noise generated inside the compressor can be effectively attenuated through the double-layer shell and the filling layer, and the radiation degree to the outside is reduced.

Description

Double-layer shell structure of rotor type compressor

Technical Field

The application relates to a double-layer shell structure of a rotor type compressor, and relates to the technical field of compressor structures.

Background

As the rotor compressor operates, noise is generated and radiated outward through the compressor housing. The existing compressor shell is of a single-layer structure, as shown in fig. 1, and is thin in thickness, noise generated inside the compressor cannot be attenuated and directly radiated to the outside when passing through the shell, so that the noise of the compressor during operation is large, and the actual use feeling of the air conditioner is influenced.

SUMMERY OF THE UTILITY MODEL

The technical problem that this application will be solved is the unable problem that limits inside noise to external spread of single-deck casing of rotor compressor.

In order to solve the technical problem, the technical scheme of this application provides a double shell structure of rotor compressor, rotor compressor has last cap, casing down, its characterized in that, still include with go up the cap casing down casing sealing connection's double-deck casing, double-deck casing is equipped with shell body, interior casing, and sets up filling layer between shell body, the interior casing.

Preferably, the end of the inner shell is hermetically connected with the upper shell cover and the lower shell.

Preferably, the outer shell and the inner shell are connected through a plurality of rib plates, the filling layer is divided into a plurality of areas by the plurality of rib plates, and the areas are filled with sound absorption materials.

Preferably, be equipped with a connecting pipe that runs through on the double shell for connect and locate outside reservoir, the connecting pipe is established in advance on shell body, the interior casing, pass interior casing and shell body in proper order and be connected with locating outside reservoir, the connecting pipe sets up shaft seal with interior casing/shell body junction.

Preferably, the inner shell of the area where the connecting pipe is located is of a honeycomb panel structure.

Detailed Description

In order to make the present application more comprehensible, preferred embodiments accompanied with figures are described in detail below.

Examples

In the present embodiment, as shown in fig. 2 and fig. 3, a compressor adopts a double-layer shell, and includes an outer shell 1 and an inner shell 2, a filling layer 3 is arranged between the outer shell 1 and the inner shell 2, and sound absorbing cotton or sound absorbing material is filled in the filling layer 3; when the compressor runs, the noise generated inside the compressor can be effectively attenuated through the double-layer shell and the filling layer, and the radiation degree to the outside is reduced.

In some possible embodiments, as shown in fig. 2, a through connection pipe 5 is provided on a shell of the compressor for the refrigerant to enter the compressor from an accumulator 6, the connection pipe 5 sequentially passes through the inner shell 1 and the outer shell 2 to be connected with the accumulator 6 located outside, and a shaft seal is provided at a connection position of the connection pipe 5 and the inner shell 1/the outer shell 2;

the outer shell 1 and the inner shell 2 are connected through a plurality of rib plates 4 distributed along the circumference, the number of the rib plates 4 distributed along the circumference is at least 4, as shown in fig. 2, the filling layer 3 is divided into a plurality of areas by the plurality of rib plates 4, the inner shell 2 in the area of the connecting pipe 5 is set as a honeycomb plate, vibration noise is easier to transmit from the area because the area of the connecting pipe 5 needs to be perforated, therefore, the inner shell 2 in the area of the connecting pipe 5 is made of the honeycomb plate, the outer shell 3 provides strength support, and the noise reduction effect can be realized through the dual noise reduction of the honeycomb plate and the filling layer 3, and at the initial stage of assembly, through the perforated holes arranged on the honeycomb plate structure, the connecting pipe 5 is pre-pressed into the perforated holes and is arranged at the joints of the inner shell 1/the outer shell 2 respectively, and shaft sealing is arranged at the joints of the inner shell 1/the outer shell 2.
