Example Embodiment

[0032] Example one

[0033] Referring to Figure 1, the compressor provided in this embodiment includes a sealed housing 2 in which a high and low pressure partition plate 21 is provided, and a fixed scroll 3 is provided under the high and low pressure partition plate 21 and cooperates with the fixed scroll 3 In order to realize the floating sealing function of the sealing cover 4 and the sealing rings 51, 52, 53, the movable scroll 6 installed opposite to the fixed scroll 3 is arranged below the fixed scroll 3, so that the two scrolls have a suction pressure zone 300 and a discharge pressure zone. A compression chamber with a gradually changing volume is generated between 400 and the sealed housing 2 is provided with a bearing seat 7 for installing the fixed scroll 3 and making it have limited axial movement relative to the movable scroll 6, and the bottom of the movable scroll 6 is with The crankshaft 8 is matched, the crankshaft 8 is matched with the motor assembly 9, the cranks...

Example Embodiment

[0042] Example two

[0043] Referring to Figure 5, the difference between the compressor with a floating sealing device provided in the second embodiment and the first embodiment is that the top end of the sealing cover 4 and the high and low pressure partition plate cooperate with the sealing mechanism used to separate the suction pressure zone and the discharge pressure zone The difference is that in the first embodiment, the groove 43 is matched with the sealing ring 53. In the second embodiment, the closed boss 44 integrally formed at the top of the sealing cover 4 and the sealing pad 211 provided at the bottom of the high and low pressure partition plate are used in the second embodiment. . This embodiment can achieve the same purpose and function as the first embodiment.

Example Embodiment

[0044] Example three

[0045] Please refer to Fig. 6, the third embodiment provides a compressor with a floating seal device and the difference between the second embodiment is that the boss on the top of the end plate of the fixed scroll 3 is a first-stage boss, which is labeled 310 in Fig. 6, and the seal The groove provided at the bottom of the cover 4 is correspondingly a first-stage groove, and the upper end of the boss 310 is partially embedded in the groove, so that a middle pressure cavity 100 is formed between the top surface of the boss 310 and the bottom surface of the groove. The first sealing element is arranged between the outer side wall of the boss 310 and the outer side wall of the groove to isolate the medium pressure chamber 100 from the suction pressure zone 300, and the second sealing element is arranged on the inner side wall of the boss 310 and the groove Between the inner side walls, the medium pressure chamber 100 is separated from the discharge pressure z...

Abstract

The present invention relates to vortex compressor, and is especially floating sealer for vortex compressor. The floating sealer includes one static eddy tray with boss in the top, and one sealing cover fitting the top of the static eddy tray. The sealing cover has one notch to fit the boss to form one medium pressure cavity between the sealing cover and the static eddy tray, and the medium pressure cavity is communicated with one discharge channel and one compression cavity in the static eddy tray. The floating sealer includes also three sealing parts. Compared with available technology, the floating sealer of present invention has the advantages of simple structure, easy installation and low cost. The vortex compressor of the present invention has high compression efficiency, low cost and high reliability.

Description

technical field [0001] The invention relates to the field of scroll compressors, in particular to a compressor with a floating sealing device and a floating sealing device used in the scroll compressor. Background technique [0002] Generally, a scroll compressor is mainly composed of a sealed casing, a movable scroll, a fixed scroll, an anti-rotation mechanism, a bearing seat, a crankshaft, and a motor assembly. There is a high and low pressure partition plate inside the sealed shell, so as to divide the interior of the sealed shell into a high pressure area (upper part) and a low pressure area (lower part), and a discharge hole is opened in the center of the high and low pressure partition plate. The static scroll has an end plate, and a discharge hole is opened in the center of the end plate, which cooperates with the discharge hole opened on the high and low pressure partition plate, and a scroll is integrally formed under the end plate. The movable scroll also has an e...
