Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal air compressors, in particular to an oil-free silent centrifugal air compressor. Background Art

[0002] Working principle of oil-free silent air compressor: Oil-free silent air compressor is a micro reciprocating piston compressor. When the motor drives the compressor crankshaft to rotate, the piston, which is self-lubricating and does not require any lubricant, moves back and forth through the transmission of the connecting rod. The working volume formed by the inner wall of the cylinder, the cylinder head and the top surface of the piston will change periodically.

[0003] For example, an oil-free silent centrifugal air compressor with publication number CN217462596U can effectively buffer the vibration generated during the operation of the centrifugal air compressor by setting a multi-layer buffer structure, thereby reducing the noise generated during the operation of the centrifugal air compressor. At the same time, the support plate can be positioned by setting a shock-absorbing rod and a pulley to avoid the support plate from deviating and causing noise.

[0004] Based on the search of patent numbers, combined with the findings of deficiencies in the prior art;

[0005] Although the existing centrifugal air compressor can buffer and eliminate noise, in actual use, the buffer structure of the centrifugal air compressor adopts a spring as the main structure, which causes the spring to continue to shake during buffering. The spring has metal fatigue, which causes the buffer structure to be easily damaged after being used for a period of time, which not only increases the economic burden of the user, but also reduces the use effect of the centrifugal air compressor.
