Oilless compressor with multiple cylinders on same plane and piston assembly performing linear reciprocating movement

Abstract

The invention provides an oilless compressor with multiple cylinders on the same plane and a piston assembly performing linear reciprocating movement. The oilless compressor is mainly composed of guide connection plates, bearings, a main shaft with an eccentric wheel, a piston seat, a venting reed, a venting opening, air cylinder covers, an air feeding / venting valve plate, a piston pressing plate, an air inlet, an air feeding valve piece, a piston, air cylinders, a box body and an end cover. Through the bearings sleeving the main shaft with the eccentric wheel, the guide connection plates and the piston assembly which is connected with the guide connection plates in a screwed manner and is symmetrically composed of the piston seat, the piston and the piston pressing plate can be driven to perform linear reciprocating movement simultaneously on the same plane; when a motor drives the main shaft with the eccentric wheel to rotate, it can be guaranteed that the piston assembly performs linear reciprocating movement in the corresponding air cylinders, the compressor is made to work continuously and stably, and noise generated by the compressor is lowered to a great extent; moreover, the multiple air cylinders can be arranged on the same plane to perform multi-stage compression; and meanwhile, by the adoption of the oilless compressor, efficiency of the compressor can be improved, the size of the compressor is effectively lowered, and the weight of the compressor is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to an oil-free compressor in which multiple cylinders are on the same plane and piston assemblies reciprocate in a straight line. Background technique [0002] Compressor is a general-purpose mechanical device that is widely used and closely related to various fields of modern industry and life and plays an important role. Compressors can be used in refrigeration, engines, gas delivery, chemical processes, machinery manufacturing, aquaculture, medical treatment and almost any place where compressed gas needs to be delivered or used. At present, the commonly used air compressors are mainly piston air compressors and screw air compressors. Although these two compressors have their own advantages, they also have certain shortcomings. For example, the piston air compressor mainly uses the rotary motion of the crankshaft to drive the piston to do a swinging reciprocatin...

AI Technical Summary

Problems solved by technology

For example, the piston air compressor mainly uses the rotary motion of the crankshaft to drive the piston to do a swinging reciprocating motion to compress the gas in the cylinder. The friction noise of the bearing bush is relatively large, the piston is easy to wear and the stability is poor; The meshing friction of the rotor, fast rotation speed and high heat generation not only require high wear resistance of the material, but also require a large amount of cooling lubricating oil when in use, and finally need to separate oil and gas, thus causing energy consumption of the screw compressor High, high cost, complex operation, difficult repair and maintenance
