Problems solved by technology

However, as the speed increases, more refrigeration oil from the compressor is pumped up by the centrifugal oil pump (the higher the speed, the stronger the pump’s oil pumping capacity), enters the cylinder, and is discharged into the refrigerator system. Excessive oil plugging will reduce the heat transfer efficiency of the system pipes, resulting in a decrease in the refrigeration capacity of the refrigerator

Abstract

The invention discloses an oiling assembly used for a refrigerator compressor and the compressor comprising the same. The oiling assembly used for the refrigerator compressor comprises an upper oiling blade and an oil pump shell, wherein an oil drainage hole and an exhaust hole are formed in the upper portion of the upper oiling blade; an oil inlet channel eccentrically formed relative to the rotation axis of a crankshaft of the compressor is defined in the upper oiling blade; the oil drainage hole and the exhaust hole communicate with the oil inlet channel; an inner cavity is defined in the oil pump shell; an oil inlet which communicates with the inner cavity is formed in the oil pump shell; the upper oiling blade is mounted in the inner cavity; an oil drainage connecting hole and an exhaust connecting hole are formed in the oil pump shell; the oil drainage connecting hole communicates with the oil drainage hole; and the exhaust connecting hole communicates with the exhaust hole. According to the embodiment, the oiling assembly used for the refrigerator compressor can effectively solve the problem that pump oil is too much when an inverter compressor rotates as high rotation speed, and machining procedures of the crankshaft can be reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an oiling assembly for refrigerator compressors and a compressor having the same. Background technique [0002] The biggest feature of the frequency conversion refrigerator compressor is that the speed of the motor is variable, the general range is about 1200-4500 rpm, while the speed of ordinary fixed-speed compressors is generally about 2900 rpm. High speed can effectively improve the refrigeration capacity of the refrigerator, increase the cooling speed of the items stored in the refrigerator, and have obvious advantages in the quick-freezing function of the refrigerator and food preservation compared with ordinary fixed-speed compressors. However, as the speed increases, more refrigeration oil from the compressor is pumped up by the centrifugal oil pump (the higher the speed, the stronger the oil pump’s oil pumping capacity), enters the cylinder and is discharged into the...
