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 a multi-cylinder opposed piston type oil-free compression device. It includes a drive motor, a cylinder and an air guide cover, and is characterized in that the output shaft of the drive motor is connected to a set of coaxially opposed piston assemblies that freely reciprocate in the cylinder, and the piston assembly is connected to the output shaft of the drive motor. On the crankshaft, a crankcase is arranged between the crankshaft and the drive motor, and the piston assembly reciprocates regularly up and down under the drive of the crankshaft. Compared with the same type of compressors, the present invention has an avant-garde design concept and changes the traditional oil-lubricated compression lubrication method; it has a novel structure, double-headed pistons with guide rings and piston cups, crankshafts with 90-degree misalignment, and 2 sets of pairs Equipped with a cylinder, it can produce uniform and pure compressed air; its structure is reliable, compact, low cost, high efficiency, low leakage, long life and good 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...
