High-pressure air compressor realizing permanent magnetic coupling regulation

Abstract

The invention discloses a high-pressure air compressor realizing permanent magnetic coupling regulation and relates to the technical field of air compressor equipment. The high-pressure air compressorcomprises a motor and a winding type permanent magnetic coupling speed regulator; the output end of the motor is coaxially connected with the input end of a winding type permanent magnetic coupling speed regulator through a first shaft coupler; the output end of the winding type permanent magnetic coupling speed regulator is coaxially connected with the input end of the air compressor through a second shaft coupler; a rotating shaft of the winding type permanent magnetic coupling speed regulator is fixedly sleeved with a collector ring; and the collector ring is electrically connected with awinding rotor core of the winding type permanent magnetic coupling speed regulator. The high-pressure air compressor disclosed by the invention can be ensured to run at a low-speed rated torque and can also output any torque to meet the use requirements under different working conditions; and when maintenance and disassembly are required, all components can be disassembled and maintained more conveniently and quickly by cooperation of plug-fixation among all the components without wasting a lot of time for disassembling and assembling the parts, so relatively high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of air compressor equipment, in particular to a permanent magnetic coupling regulating high-pressure air compressor. Background technique [0002] Air compressors are widely used in ventilation and dust removal of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances ; Drying and selection of grain; Wind tunnel wind source and inflation and propulsion of hovercraft, etc. Commonly used speed control products for air compressors include frequency converters, hydraulic coupling speed governors, eddy current permanent magnet speed governors, etc. [0003] The frequency converter needs to be matched with a special frequency conversion motor when adjusting the air compressor. Because the frequency converter is prone to generate different levels of harmoni...
