Abstract

The invention discloses a piston type oil-less air compressor. The piston type oil-less air compressor comprises a machine base, a crank case fixed on the machine base, a primary cylinder I, a primary cylinder II, a primary cylinder III, an intermediate cooler, a primary air-water separator, a secondary cylinder I, a secondary cylinder II, an after-cooler, a secondary air-water separator and an air storage tank fixed on the machine base. The primary cylinder I, the primary cylinder II and the primary cylinder III are fixed on the crank case respectively and distributed in a fan-shaped mode, an included angle between the primary cylinder I and the primary cylinder II and between the primary cylinder III and the primary cylinder II are 40-55 degrees, and the secondary cylinder I and the secondary cylinder II are arranged on the left side and the right side of the crank case respectively. By adopting the technical scheme, the piston type oil-less air compressor is compact in structure, a space occupied by the air compressor is saved, the installing area of a valve is increased, cooling is facilitated, the effective volume flow and exhaust pressure of the piston type oil-less air compressor are improved, an application range is expanded, the service life and the air quality are prolonged and improved, and the working reliability is improved.

Description

technical field [0001] The invention relates to a compressor, in particular to a small piston type oil-free air compressor with a volumetric flow rate of 5.5 cubic meters per minute and an exhaust pressure of 0.8 MPa. Background technique [0002] The volume flow rate of a single machine of the existing oil-free air compressor does not exceed 3.0 cubic meters per minute, and the compressors with a volume flow rate exceeding 3.0 cubic meters per minute are all screw machines on the market, and oil-free screw machines are expensive and costly , bulky, takes up a lot of space, and has low efficiency in processing and manufacturing. However, the small air compressor with oil screw has low efficiency and small volume specific energy, and cannot meet the needs of industries such as food, medical treatment, pharmaceuticals, and precision instruments. Contents of the invention [0003] The object of the present invention is to provide a kind of volumetric flow rate is 5.5 cubic m...
