Problems solved by technology

The lubricating oil inside the compressor flows into the oil pool through the oil hole of the crankshaft. Due to the existence of the pressure difference, the lubricating oil in the oil pool can enter the back pressure cavity through the seal ring cutout, and then supply the dynamic and static discs for sealing and lubrication. The amount of lubricating oil entering the back pressure chamber from the cutout of the sealing ring is affected by the amount of lubricating oil in the oil pool of the upper bracket
In fact, since the oil return hole is connected under the oil pool of the upper bracket, after the lubricating oil enters the oil pool of the upper bracket through the oil hole of the crankshaft, it will quickly flow out of the oil pool under the action of gravity, and return to the bottom of the compressor through the oil return hole of the upper bracket. Therefore, the amount of lubricating oil that enters the back pressure chamber through the oil pool and the seal ring cutout will be reduced, which will affect the lubrication between the moving disc and the static disc.

Abstract

The invention provides a scroll type pump body, a compressor and an air conditioner. The scroll type pump body comprises a static disc and a dynamic disc which are engaged with each other and a supporting rack used for supporting the static disc and the dynamic disc, a crankshaft is connected with the supporting rack through a bearing and forms a bearing cavity, the side, facing the supporting rack, of the dynamic disc is structured with a lubricating oil passage, a back pressure cavity is formed between the dynamic disc and the supporting rack, and the lubricating oil passage can cut throughthe bearing cavity and the back pressure cavity alternatively along with sliding of the dynamic disc. According to the scroll type pump body, the compressor and the air conditioner, the lubricating oil quantity of the static disc and the dynamic disc can be significantly increased, the pump body lubricating effect is guaranteed, and then the working performance of the pump body is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a scroll pump body, a compressor and an air conditioner. Background technique [0002] Scroll compressor is a positive displacement compressor with high efficiency, low noise and stable operation. It has been widely used in air-conditioning and refrigeration units in recent years. Generally speaking, a scroll compressor is composed of a closed shell, a moving disk, a static disk, a crankshaft, an anti-rotation mechanism, and a motor. working cavity. Driven by the crankshaft, the moving disk revolves around the center of the static disk and performs translational motion without rotation with a fixed radius of gyration. The crescent working chamber continuously moves toward the center, its volume shrinks and the pressure rises continuously until it communicates with the central exhaust hole, and the high-pressure refrigerant It is discharged from the pump bod...
