A low energy consumption oil-free silent air compressor

Abstract

The invention discloses a low-energy-consumption oilless silence air compressor. The low-energy-consumption oilless silence air compressor comprises at least one air cylinder assembly. Each air cylinder assembly comprises a piston and an air cylinder containing the piston, wherein a ceramic film layer is arranged on the inner wall of a cylinder sleeve of the air cylinder, the piston comprises a piston body, a composite material layer arranged on the outer side of the piston body in a sleeving manner, a piston ring embedded in the outer side of the composite material layer, and the piston ring and the composite material layer are made of the same materials and prepared through carbon material containing composite materials. During work, each piston reciprocates in the corresponding cylinder sleeve, each piston ring rubs with the ceramic film layer on the inner wall of the corresponding cylinder sleeve, the composite material layer on the outer side of each piston body plays a guiding role in the corresponding cylinder sleeve, and therefore the friction coefficient between each piston and the corresponding cylinder sleeve is reduced, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to an oil-free silent air compressor with low energy consumption. Background technique [0002] An air compressor (referred to as an air compressor) is a device used to compress gas, which can convert mechanical energy into gas pressure energy. Air compressors are similar in construction to water pumps, most air compressors are reciprocating piston, rotating vane or rotating screw. [0003] In reciprocating piston air compressors, the cylinder liners of some existing air compressors are made of metal, the surface of the cylinder liner is electroplated, and the piston rings are made of metal or non-metal. The friction temperature is high when the piston moves, and oil is needed to lubricate the cylinder components. The oil consumption is high, and the compressed air contains oil particles, so the piston ring needs to use multiple channels to ensure the sealing, which increas...

AI Technical Summary

Problems solved by technology

[0003] In reciprocating piston air compressors, the cylinder liners of some existing air compressors are made of metal, the surface of the cylinder liner is electroplated, and the piston rings are made of metal or non-metal. The friction temperature is high when the piston moves, and oil is needed to lubricate the cylinder components. The oil consumption is high, and the compressed air contains oil particles, so the piston ring needs to use multiple channels to ensure the sealing, which increases the friction surface and makes the machine less efficient;

[0004] Moreover, in the valve plate assembly of the existing air compressor, springs are used on both sides of the valve plate to achieve elastic limit, and the side of the valve plate corresponding to the valve plate is generally a planar structure, so that the valve plate falls back on the valve plate It has a large impact area, which makes the valve plate have a large knocking noise during the working process;

[0005] In addition, most of the cylinder head of the existing air compressor adopts an external open cooling method, which makes the cylinder head of the existing air compressor not only poor in cooling effect, easy to cause burns to the user, but also noisy, requiring additional external cooling. silencer, which increases the cost
