Problems solved by technology

This phenomenon lasts for more than 15 minutes, during which the lack of lubricating oil in the casing leads to a decrease in the oil supply of the centrifugal pump, which becomes the main cause of compressor failure.

Abstract

The invention discloses a scroll compressor and a refrigeration cycle device with the scroll compressor. An electric motor, a compression mechanism part and lubricating oil are contained in a sealingshell of the scroll compressor, wherein the electric motor consists of a stator, a rotor and the like; the compression mechanism part is driven by the electric motor; the lubricating oil is used for lubricating the compression mechanism part; the compression mechanism part comprises a stationary disc, a movable disc, a crankshaft, a first bearing, oil-containing gases and a sliding surface; the crankshaft is fixed with the rotor; the first bearing is positioned between the movable disc and the rotor and is connected with the crankshaft in a sliding manner; the oil-containing gases are discharged from a compression chamber consisting of the stationary disc and the movable disc; the sliding surface is used for at least lubricating the crankshaft and the first bearing. According to the scrollcompressor disclosed by the invention, the lubricating oil can uniformly and rapidly lubricate sliding parts.

Description

technical field [0001] The present invention relates to a new oil supply method and a lubrication method introduced in the lubrication of sliding parts of a scroll compressor in which the inner pressure of a housing is regarded as a high pressure. For the spray lubrication generated by the original centrifugal oil supply pump that uses the crankshaft rotation, the present invention adopts the spray lubrication generated by the high-pressure oil-containing gas discharged from the compression chamber. Background technique [0002] Conventional scroll compressors have used centrifugal oil supply pumps or forced pumps that use the rotation of the crankshaft to lubricate the crankshaft and rotor. Furthermore, the high-pressure gas (refrigerant) discharged from the compression chamber is discharged into the casing, and the lubricating oil contained in the high-pressure gas is recovered to the bottom of the casing. The lubricating oil that cannot be recovered is discharged togethe...
