Suction muffler and compressor having same

Abstract

The invention discloses a suction muffler and a compressor with the same. The suction muffler comprises: a housing, the housing has a suction port and an air outlet, and a The gas port and the airflow channel of the air outlet; the oil retainer, the oil retainer is arranged on the housing, the oil retainer protrudes from the outer wall of the housing and extends outward, and at least a part is located on the directly above the suction port. According to the suction muffler of the embodiment of the present invention, it is difficult for the refrigerant to bring the refrigerating machine oil into the suction muffler from the suction port, so that the amount of refrigerating machine oil flowing into the compression cavity with the refrigerant is greatly reduced, and the discharge of the compressor The oil quantity is reduced, and the safety and reliability are improved.

Description

technical field [0001] The present invention relates to the technical field of compressors, more specifically, to a suction muffler and a compressor with the suction muffler. Background technique [0002] The fully enclosed refrigerator compressor has an eccentric hole on the crankshaft. The motor drives the crankshaft to rotate, so that the refrigerating machine oil at the bottom of the compressor shell generates an upward centrifugal force, and then is thrown to the moving parts through the eccentric shaft. During the lubrication process, only a small part of the refrigerating machine oil enters the cylinder for lubrication, and most of the refrigerating machine oil splashes around the pump body and the inner wall of the casing, and then flows back to the bottom of the compressor under the action of gravity. Refrigerator oil that returns to the bottom of the compressor can be cycled back and forth again. [0003] In the related art, the oil discharge volume of the compres...

Problems solved by technology

[0004] 1. The large amount of oil discharged by the compressor may lead to increased viscosity of the recovered oil when the refrigerating machine oil in the compressor passes through the low-temperature part after being discharged, resulting in insufficient lubrication of the refrigerating machine oil in the compressor and increased wear, affecting the life and reliability of the compressor sex

[0005] 2. The large amount of oil discharged by the compressor may cause the refrigerating machine oil in the compressor to be partially decomposed in the high-temperature part, and the degraded product of the discharged oil will form carbon deposits and accumulate in the valve part, causing the gas to flow back, and the temperature of the compression part will rise, which will further promote the accumulation. Accelerated formation of carbon

[0006] 3. The large amount of oil discharged by the compressor may cause corrosive acid to be generated when the refrigeration oil in the compressor deteriorates, causing corrosion of internal parts and causing the motor to burn out
