Embodiment Construction

[0031] The multi-cylinder opposed piston type oil-free compression device includes a drive motor, a cylinder and an air guide cover. The output shaft of the drive motor is connected to a set of coaxially opposed piston assemblies that freely reciprocate in the cylinder. The piston assemblies are connected to the On the crankshaft connected to the output shaft of the drive motor, a crankcase is arranged between the crankshaft and the drive motor, and the piston assembly moves up and down regularly under the drive of the crankshaft.

[0032] Output shafts can be arranged on both sides of the drive motor, and the two output shafts of the drive motor are connected to a group of coaxially opposed piston assemblies that freely reciprocate in the cylinder. At this time, the crankshafts on both sides of the drive motor need They are staggered 90 degrees from each other, and the angles are staggered within one rotation cycle to achieve uniform compression.

[0033] The above-mentioned ...

Abstract

The invention relates to an oilless compression device with multiple cylinders and opposite pistons. The oilless compression device comprises a driving motor, a cylinder and an air guiding cover, and is characterized in that an output shaft of the driving motor is connected with a group of piston subassemblies which share a shaft, are opposite to one another and freely move in the cylinders in a reciprocating manner; the piston subassemblies are connected to crankshafts which are connected with the output shaft of the driving motor; a crankcase is arranged between each crankshaft and the driving motor; and the piston subassemblies are driven by the crankshafts to regularly move vertically in a reciprocating manner. Compared with a like compressor, the oilless compression device has the advantages that the design thought is fashionable; the traditional oil lubrication mode or the traditional compression lubrication mode is changed; the structure of the oilless compression device is novel; each double-head piston is provided with a guiding ring and a piston cup, the crankshafts are arranged perpendicularly in a staggered manner, the two cylinders are opposite to each other, and uniform and pure compressed air can be yielded; and the oilless compression device is reliable and compact in structure, low in cost, high in efficiency, low in leakage, long in service life and high in stability.

Description

technical field [0001] The invention relates to a multi-cylinder opposed piston type oil-free compression device. Background technique [0002] The oil-opposed-piston structure, as a mature known technical structure, is widely used in engine devices and oil-containing compression devices. Although this structure is reliable and efficient, it is inseparable from the protection of lubricating oil. As an air source that can provide clean air, oil-free compressors have a very wide market in medical, food, chemical and other industries that require high air quality. At present, oil-free piston compressors mostly use synthetic materials as piston rings. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a technical solution of a multi-cylinder opposed-piston oil-free compression device. [0004] The multi-cylinder opposed piston type oil-free compression device includes a drive motor, a cylinde...
