Abstract

A unit for preventing reverse rotation of vortex compressor, which has a rotary shaft with moving vortex disk, the compression unit composed of moving and static vortex disks, power generating unit, lubricating unit and reverse rotation preventer, features that it is arranged on main frame and moving vortex disk. When said moving vortex is going to rotate reverse, an elastic limiting pin moves upward and is hooked by a slot only main frame, so preventing the reverse rotation of moving vortex disk.

Description

technical field [0001] The invention relates to an anti-reversal device of a scroll compressor, in particular to a scroll compressor which is provided with an anti-reversal device on the movable scroll and the main frame supporting the movable scroll to prevent the reverse rotation of the movable scroll and the rotating shaft. Compressor anti-reverse device. Background technique [0002] Generally speaking, a scroll compressor is a type of rotary compressor, which is a volumetric compressor that compresses refrigerant through the rotational movement of a pair of matching turbine parts, where the tooth shape of the turbine parts is an involute. The refrigerating capacity range of the scroll compressor is 2500~4300Kcal / h. In order to improve its efficiency, the processing of the turbine parts must be precise. The recent development of manufacturing technology can achieve high-precision processing. Therefore, the scroll compressor is widely used in the field of air conditioning...
