Problems solved by technology
However, when the lubricating oil inside the reciprocating compressor is circulated and lost in the refrigeration system, the oil volume inside the casing will decrease sharply, and the liquid level of the lubricating oil will also drop. The loss of pump oil can only be ensured by sealing more lubricating oil to ensure sufficient lubricating oil balance

The invention discloses a compressor, a refrigeration system with the same and a refrigerator. The compressor comprises a shell, a crankshaft and an oil pump, the bottom in the shell is provided withan oil pool, the crankshaft is arranged in the shell, the oil pump comprises a first oil pump shell and a second oil pump shell, the first oil pump shell is connected to the lower end of the crankshaft, the second oil pump shell is arranged in the first oil pump shell and can move up and down relative to the first oil pump shell, and the lower end of the second oil pump shell extends into the oilpool. According to the compressor, the oil pump comprising the first oil pump shell and the second oil pump shell capable of moving up and down relative to the first oil pump shell is arranged, and the lower end of the second oil pump shell is suitable for extending into the oil pool, the oil pump can be in contact with the bottom of the shell without damage under condition of transporting and dropping of the compressor; and the distance between the oil pump and the bottom of the shell is relatively reduced, so that the utilization rate of lubricating oil is improved, and pump oil loss is reduced when the liquid level in the oil pool is lowered.
Description
technical field [0001] The invention relates to the technical field of compressor manufacturing, in particular to a compressor, a refrigeration system and a refrigerator having the same. Background technique [0002] In refrigeration compressors, lubrication between relatively moving parts is extremely important. Especially in reciprocating compressors, since the housing is flexibly connected to the movement inside the housing, the oil pump lubrication system, such as the oil pump, is relatively more complex in its environment. [0003] In the related art, the distance between the oil pump of the reciprocating compressor and the bottom of the casing must be greater than the distance of the support limit to prevent the oil pump from colliding with the casing. Therefore, the distance between the oil pump and the bottom of the casing is generally larger. This also causes a large part of the lubricating oil of the reciprocating compressor to deposit on the bottom of the shell ...
