Horizontal compressor

Abstract

The invention comprises a horizontal type compressor which comprises a housing in which a motor and a compression pump body are arranged, wherein the motor drives a compressor rotating shaft to rotate; a pump body rotating shaft of which the axis is overlapped with the axis of the compressor rotating shaft is arranged in the compression pump body; a pump body cover plate is arranged between the motor and the compression pump body; a bearing support is arranged in the housing; the compressor rotating shaft is arranged on the bearing support through a bearing; first magnetic steel is arranged on the second end part of the compressor rotating shaft; the first end part of the pump body rotating shaft penetrates through a pump body cover plate, and second magnetic steel is arranged on the first end part; a non-magnetic isolation sleeve is arranged between the first magnetic steel and the second magnetic steel and is used for isolating the first magnetic steel from the second magnetic steel; the second magnetic steel is positioned in the first magnetic steel; the inner side surface of the first magnetic steel is a slope; the second magnetic steel is provided with an outer side surface, and the inclination angle of the outer side surface of the second magnetic steel is the same as that of the inner side surface of the first magnetic steel. The horizontal type compressor has the characteristics of small vibration and high motor efficiency.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to a horizontal compressor in which a compression pump body and a motor are separated. Background technique [0002] like figure 1 and figure 2 As shown, the hermetic horizontal rotary compressor used in air conditioners and other household appliances usually includes an outer shell 100, a motor, a compressor shaft 102, a compression pump body, a gas-liquid separator 103, a suction pipe 104 and an exhaust pipe 105 . Wherein, the motor is composed of a stator 106 and a rotor 107, and the compression pump body communicates with the gas-liquid separator 103 through the suction pipe 104. The compression pump body in the compressor plays the role of compressing the refrigerant, which is used to suck and compress the refrigerant, and then output the high-temperature and high-pressure refrigerant. The compression pump body of the compressor generally includes a cylinder 108 , a ro...

Problems solved by technology

[0003] The exhaust of the conventional horizontal compressor is below the motor, the exhaust air flow path is long and changes in many directions, the air flow on the upper and lower sides of the stator is inconsistent, resulting in uneven heat dissipation of the motor stator, and the conventional horizontal compressor, the refrigerant passes through the compressed pump body After compression, it needs to pass through the motor and other components in the outer shell before being discharged from the exhaust pipe at the top of the outer shell

Since the high-temperature and high-pressure refrigerant directly contacts the motor and other components in the outer casing, the high-temperature and high-pressure exhaust will have an adverse effect on the overload capacity and reliability of the motor; at the same time, the motor, overload and other electrical components that may have ignition Direct contact with refrigerant reduces the safety of some flammable and explosive environmentally friendly refrigerants such as R290 on horizontal compressors, and also limits the use of hydrocarbon refrigerants with high exhaust temperatures such as R32 on horizontal compressors usage of
