Horizontal compressor

Abstract

The invention relates to technical field of compressors, and discloses a horizontal compressor. The horizontal compressor comprises a shell body (1), a compressing mechanism (3), a motor (2) and a gasguiding device (5). The compressing mechanism is arranged in the shell body and comprises a main bearing (6). The motor drives the compressing mechanism to work and is provided with an insulating terminal board (4). The gas guiding device comprises a motor connection terminal and a compressing mechanism connection terminal. The motor connection terminal is connected with the insulating terminal board in a sealed way. The compressing mechanism connection terminal is in abut joint with the main bearing, and forms a terminal face seal with the main bearing. An airflow channel is formed between the compressing mechanism and the motor. The airflow channel passes through an inner cavity of the gas guiding device. The design of the horizontal compressor effectively improves the air tightness between the gas guiding device and the compressing mechanism. Thus, a refrigerant is prevented from flowing out from the gap between the gas guiding device and the compressing mechanism. The horizontal compressor can improve the cooling effect of the motor and the oil-gas separating effect of the refrigerant, thereby improving energy efficiency and reliability of the horizontal compressor.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a horizontal compressor. Background technique [0002] Compressors (such as horizontal compressors) are widely used. In order to reduce the oil output of the compressor, a gas guide device is usually added between the compression mechanism and the motor, so that a passing air gap is formed between the compression mechanism and the motor. The gas flow channel of the inner cavity of the gas guiding mechanism. [0003] But at present, due to the limited assembly process, there is often an assembly gap between the gas guiding device and the compression mechanism, so that most of the refrigerant discharged from the compression mechanism no longer flows through the motor, but directly flows away from the assembly gap. In this way, Not only will the cooling effect of the motor be reduced, but the refrigerant will not be able to fully separate oil and gas, thereby greatl...

[0003] But at present, due to the limited assembly process, there is often an assembly gap between the gas guiding device and the compression mechanism, so that most of the refrigerant discharged from the compression mechanism no longer flows through the motor, but directly flows away from the assembly gap. In this way, Not only will it reduce the cooling effect of the motor, but it will also prevent the refrigerant from fully separating oil and gas, thereby greatly reducing the role of the gas guide device in reducing the oil output of the compressor, and reducing the energy efficiency and reliability of the compressor
