Abstract

The invention provides a crankshaft oil pumping assembly, a crankshaft assembly and a compressor, the crankshaft oil pumping assembly comprises a shell, a check block, an elastic piece and an oil guide sheet, wherein a flow channel allowing lubricating oil to circulate is formed in the shell, an oil suction port and an oil outlet are formed in the two ends of the flow channel respectively, the check block is movably arranged in the flow channel, the check block is close to or far away from the oil outlet to control the size of an oil outlet flow path, the elastic piece is connected with the check block and used for providing elastic force towards the oil suction port for the check block, the oil guide sheet is fixedly arranged in the flow channel, and the oil guide sheet separates the oilsuction port from part of the flow channel close to the oil suction port. According to the crankshaft oil pumping assembly, the crankshaft assembly and the compressor, the oiling amount can be adjusted in a self-adaptive mode along with the rotating speed, and excessive oil amount is avoided.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a crankshaft pump oil assembly, a crankshaft assembly and a compressor. Background technique [0002] At present, inverter refrigerator compressors are developing in the direction of miniaturization, high efficiency and broadband. In the existing refrigeration compressor lubrication system, the pump oil is controlled by the speed of the compressor, and the pump oil volume and the oil throwing height of the crankshaft increase with the increase of the speed. When the compressor is running at low speed, the amount of oil pumped by the compressor is too small, and the lubrication effect of moving parts such as bearings and pistons is poor, which will easily cause wear and tear on important parts of the compressor pump body. When the rotational speed is too low, the oil throwing height of the crankshaft is also low, and the lubricating oil cannot reach the cylinder head and othe...
