Embodiment Construction

[0012] A scroll compressor, comprising a motor 12, a crankshaft 13, a movable scroll 3, a fixed scroll 2, an Oldham slip ring 4, a support frame 16, a casing 14, the motor 12, a crankshaft 13, and a movable scroll 3 , the fixed scroll 2, the Oldham slip ring 4, and the support frame 16 are all on the low-pressure side connected to the compressor suction port 5, the fixed scroll 2 is fixed on the support frame 16, and the movable scroll 3 is placed between the fixed scroll 2 and the Between the supporting frame 16, there is a certain gap in the axial direction to realize the axial floating of the movable scroll 3, and the movable scroll 3 and the fixed scroll 2 are coupled through the Oldham slip ring 4 to form at least one pair of relatively closed compression Cavities 25 and 26 are characterized in that a first sealed cavity 8 and a second sealed cavity 10 are provided between the back of the movable scroll 3 and the end surface of the support frame 16, which are respectively ...

Abstract

The invention discloses a scroll compressor with an axially flexible seal. Two backpressure cavities are arranged between a dynamic vortex plate 3 and a support frame 16, and are respectively communicated with a scroll compression cavity and an exhaust cavity, the dynamic vortex plate 3 and a static vortex plate 2 are axially close, so that an axial seal of the dynamic vortex plate 3 and the static vortex plate 2 is realized, and sliding abrasion and power consumption between the dynamic vortex plate 3 and a thrust surface 24 of the support frame 16 can be reduced.

Description

technical field [0001] The invention relates to a scroll compressor, and also relates to an axial flexible sealing technology of the scroll compressor. Background technique [0002] As a positive displacement compressor, the scroll compressor has the advantages of high energy efficiency and small size, and has been widely used in the fields of air compression, air conditioning and refrigeration. The application of the axial flexible sealing technology improves the sealing of the scroll end face, improves the volumetric efficiency of the compressor, and reduces the processing and assembly difficulty of the compressor due to its insensitivity to axial dimension deviation. [0003] A scroll compressor usually includes a motor, a crankshaft, a movable scroll, a fixed scroll, an anti-rotation mechanism, a support frame, an unloading sleeve, and a casing. One side of the fixed scroll substrate is provided with a scroll growing along the axis, and the other side is provided with a...
