Abstract
The utility model relates to a low-noise reciprocating piston air compressor, which comprises an air cylinder, a piston, a connecting rod, a crank shaft and a crank case. A sealing ring or a sealing cup made of self-lubricating material is installed on the piston; the piston is installed in the air cylinder and in sliding fit with the air cylinder; a crank case cover is firmly connected on the crank case; a sealed crank case air admission anechoic chamber is formed by the crank case and the crank case cover; the crank case air admission anechoic chamber encloses the connecting rod and the crank shaft; and in addition, the compressor adopts a single-cylinder single-piston structure type or a double-cylinder double-piston structure type. As the mechanical noise caused by the connecting rod and the crank shaft is sealed in the crank case air admission anechoic chamber, outward-radiated noise is weakened; as the rigidity of the crank case is strengthened, mechanical vibration noise is reduced; as the volume of the air admission anechoic chamber is greatly increased, air admission noise is effectively controlled; and as the double-cylinder type is adopted to ensure that the rotation speed of the compressor is greatly reduced, mechanical vibration noise is greatly reduced.
Description
Technical field
The utility model belongs to the reciprocating-piston air compressor technical field, particularly has the reciprocating-piston air compressor of low-noise structural.
Background technique
Air compressor is a kind of use electronic product very widely, yet it is found that, air compressor tends to send very big noise when work.Studies show that the noise contribution of compressor mainly stems from induction noise, exhaust sound and mechanical noise, and these generating noise depend on the concrete structure of compressor to a great extent.A kind of reciprocating-piston type oil-less air compressor with appearance in recent years is an example, just there is greatest relation in the noise that it sends with its topology layout, referring to Fig. 1 and Fig. 2, this compressor has a cylinder 1, a piston 2, a connecting rod 3, bent axle 4 and crankcase 5, wherein be fitted with seal ring or the sealing cup made of self-enrichment material on the piston 2, piston 2 is positioned in to move back and forth in the cylinder 1 and with cylinder 1 and cooperates, one end of cylinder 1 is fixedly mounted on the crankcase 5, an other end of cylinder 1 is fastenedly connected with cylinder head 6, be connected with air-strainer 7 on the described cylinder head 6, one end of described connecting rod 3 and piston 2 be fastenedly connected or with its integral production, the other end of connecting rod 3 then is sleeved on the bent axle 4 rotationally by an oil-impregnated bearing, bent axle 4 is provided with an equilibrium block 8, the great advantage of above-mentioned compressor is not consume lubricant oil substantially, therefore can provide the not high-quality pressurized air of oil-containing, this also is the main cause that such compressor is referred to as oil-free air compressor, owing to do not need to store lubricant oil, so its crankcase 5 all becomes open structure, this is a macrostructure characteristic of such reciprocating type oil-free air compressor; Because the high-pressure air of output not oil-containing and working service is very convenient, so such compressor has obtained very fast development.But, there is a problem demanding prompt solution in above-mentioned reciprocating-piston type oil-less air compressor, Here it is, and it can send very big noise when work, trace it to its cause and mainly contain two aspects: 1) topology layout of this compressor does not meet the low noise requirement, specifically be exactly that it adopts the crankcase 5 of Open architecture very unfavorable for the control noise, this is because open crankcase 5 causes piston 2, connecting rod 3, bent axle 4 and equilibrium block 8 are in the exposed or half-naked state that reveals, gas noise that air produces is stirred and bounced in the mechanical noise that the above-mentioned movement parts of result is produced and their very easily to external radiation, open crankcase 5 has also weakened the integral rigidity of compressor simultaneously, increased crankcase 5, the elastic deformation amount of cylinder 1 and cylinder head 6 and jitter amplitude have also aggravated the generation and the radiation of mechanical noise undoubtedly; 2) this compressor has very big induction noise, there is the oil lubrication air compressor the same with traditional, oil-free air compressor also is provided with intake noise reduction chamber 9 in cylinder head 6, suction port 10 and breather check valve 11, its air inlet path is: atmosphere → air-strainer 7 → intake noise reduction chamber 9 → suction port, 10 → breather check valve, 11 → cylinder 1, although intake noise reduction chamber 9 also can be arranged in the air-strainer 7, but no matter be in cylinder head 6 or in air-strainer 7, the volume in intake noise reduction chamber 9 all will inevitably be subjected to strict harsh restriction and can not do big, well known fact is, induction noise belongs to the very wide in range air pulsing noise of a kind of frequency distribution, to its one of the most effective way that weakens is exactly to adopt big noise elimination volume, promptly utilize so-called " capacitive reactance noise-cancelling theory " to eliminate the noise, obviously imprison in the noise elimination effect in the above-mentioned intake noise reduction of capacity limitation chamber 9 relatively poor, the requirement that does not reach low induction noise.
