Problems solved by technology

[0003] For the existing DC compressors, because the volume of the vehicle-mounted small DC refrigerators and refrigerators is limited by the vehicle space, the existing small DC compressors still have high noise, and impurities are likely to be generated when the internal frame collides with the shell during operation, causing internal structure damage. Damage; the existing compressor crankshaft has a spira

Abstract

The invention discloses a direct-current compressor, and belongs to the technical field of compressor equipment. According to the direct-current compressor, a compressor shell and a shell top cover are combined to form an oval shape, so that the occupied space is smaller, the internal structure is more compact, and the height is lower; through a left anti-collision block and a cylinder head anti-collision block, when a rack shakes, collision noise is reduced after the rack touches the shell top cover, and impurities cannot be generated due to friction between metal after collision; the climbing oil storage capacity of a crankshaft is improved, lubricating oil can efficiently lubricate a crankshaft body through a spiral groove, the lubricating performance between the crankshaft body and therack is improved, abrasion locking between the crankshaft body and the rack is reduced, the service life is prolonged, and the noise is reduced; and due to the improvement in the lubricating performance of the crankshaft body, a motor can increase corresponding rotating speed to drive a long shaft of the crankshaft, the working efficiency of a pressure pumping mechanism is improved, and large cooling capacity of the device is improved along with the improved working efficiency of the pressure pumping mechanism.

Description

technical field [0001] The invention belongs to the technical field of compressor equipment, and in particular relates to a DC compressor. Background technique [0002] With the rapid development of industrial technology, compressors have gradually become indispensable key equipment in various sectors of the country's economic pillar industries, and the crankshaft is the main moving part of the reciprocating piston compressor. It has a decisive and important influence on quality, work safety and service life. [0003] For the existing DC compressors, because the volume of the vehicle-mounted small DC refrigerators and refrigerators is limited by the vehicle space, the existing small DC compressors still have high noise, and impurities are likely to be generated when the internal frame collides with the shell during operation, causing internal structure damage. Damage; the existing compressor crankshaft has a spiral groove structure outside the long axis of the crankshaft, w...
