Abstract
The utility model discloses a full oil-free air compressor which comprises a compressor base as well as a left air cylinder and a right air cylinder, wherein pistons are respectively arranged inside cylinder bodies of the left air cylinder and the right air cylinder; the left air cylinder and the right air cylinder are range type air cylinders respectively, respectively consist of first-stage air cylinders, second-stage air cylinders and three-stage air cylinders and are respectively and fixedly arranged on two sides of a central axis of the compressor base; an included angle of 90 degrees is formed between the left air cylinder and the right air cylinder; the upper ends of the left air cylinder and the right air cylinder are connected through an upper pipeline; and the lower ends of the left air cylinder and the right air cylinder are connected through a lower pipeline. Due to the adoption of the technical scheme provided by the utility model, the exhaust pressure of the full oil-free air compressor is effectively improved, the application range is widened, the practical life is prolonged and the work reliability is enhanced.
Description
(1) technical field:
The utility model relates to a kind of compressor, and particularly relating to a kind of volume flow is that 1.3 cubic meters per minute, exhaust pressure are the small-sized oilless air compressor of 3MPa.
(2) background technique:
Existing volume flow is that volume flow is 1.3 cubic meters per minute, and exhaust pressure is that common employing of the air compressor of 3MPa has oil lubrication, like the C-80/30 type; Its cylinder adopts that two row cylinders are vertical to be arranged on the body; Be equipped with piston in the cylinder, the cylinder mouth of cylinder is equipped with cylinder cap, this air compressor; Technical maturity can reach user's requirement basically.But the efficient of this design of mini air compressor is lower, and the volume specific energy is little.In addition; The bent axle of existing light duty compressor is 180 ° of crutches crank throw alternate angles, thereby makes the bent axle processing request high, and connecting rod bottom-end bearing also can only adopt the separated type sliding bearing; And can not adopt the closed bearing of integrated type, therefore low in processing, manufacture view efficient.
(3), summary of the invention:
The purpose of the utility model is to provide a kind of oilless air compressor, and this compressor has improved the exhaust pressure of oilless air compressor effectively, has enlarged application area, and has improved physical life, has increased functional reliability.
For achieving the above object, a kind of oilless air compressor of the utility model comprises that support, cylinder interior are provided with the left cylinder and the right cylinder of piston; Left side cylinder and right cylinder are formed by one-level cylinder, secondary cylinder and three-stage cylinder; It is characterized in that: left cylinder and right cylinder are extreme difference formula cylinder, are separately fixed at the both sides, medial axis of support, and the angle between left cylinder and the right cylinder is 90 °; The upper end of left side cylinder and right cylinder links to each other through last pipeline, and the lower end is through pipeline is continuous down.
The cylinder diameter of the one-level cylinder in said left cylinder and the right cylinder is 120mm～145mm.
The cylinder diameter of the secondary cylinder in said left cylinder and the right cylinder is 80mm～100mm.
The cylinder diameter of the three-stage cylinder in said left cylinder and the right cylinder is 45mm～55mm.
Piston stroke in said left cylinder and the right cylinder is 80mm～120mm.
The cylinder diameter of the one-level cylinder in said left cylinder and the right cylinder is 130mm.
The cylinder diameter of the secondary cylinder in said left cylinder and the right cylinder is 90mm.
The cylinder diameter of the three-stage cylinder in said left cylinder and the right cylinder is 50mm.
Cylinder piston stroke in said left cylinder and the right cylinder is 100mm.
In technique scheme, two extreme difference formula cylinders about the left and right sides, medial axis of support fixedly installs, and the layout symmetry angle of both sides cylinder is 90 °, V-shaped layout.Layout has been saved taking up room of machine like this, has increased the erection space of valve and has been beneficial to air-cooled cooling, has improved the exhaust pressure of oilless air compressor effectively, has enlarged application area, and has improved physical life, has increased functional reliability.
(4), description of drawings:
Fig. 1 is the structural representation of a kind of oilless air compressor of the utility model.
(5), embodiment:
Below in conjunction with accompanying drawing a kind of oilless air compressor of the utility model is done further explain.
Present embodiment is to be 1.3 cubic meters per minute in volume flow, and exhaust pressure is the example that is applied as on the small-sized oilless air compressor of the VF-1.3/30 of 3MPa.Visible by Fig. 1; A kind of oilless air compressor of present embodiment comprises that support 1, cylinder interior are provided with the left cylinder 2 and the right cylinder 5 of piston, and left cylinder 2 is formed by one-level cylinder, secondary cylinder and three-stage cylinder with right cylinder 5; Left side cylinder 2 is extreme difference formula cylinder with right cylinder 5; Be separately fixed at the both sides, medial axis of support 1, the angle between left cylinder 2 and the right cylinder 5 is 90 °, V-shaped layout; The upper end of left side cylinder 2 and right cylinder 5 links to each other through last pipeline 3, and the lower end is through pipeline 4 is continuous down.In the present embodiment, the cylinder diameter of the one-level cylinder in left cylinder 2 and the right cylinder 5 is 130mm, and the cylinder diameter of secondary cylinder is 90mm, and the cylinder diameter of three-stage cylinder is 50mm, and the cylinder piston stroke is 100mm.In the present embodiment; V-shaped layout between left side cylinder 2 and the right cylinder 5 has been saved taking up room of machine, has increased the erection space of valve and has been beneficial to air-cooled cooling; Improved the exhaust pressure of oilless air compressor effectively; Enlarge application area, and improved physical life, increased functional reliability.
