Abstract
The utility model discloses an oil-free piston air compressor, which mainly comprises an electric control portion, a driving portion, a compression main machine and a cooling system. The compression main machine comprises a crankshaft box and an air cylinder, wherein the air cylinder is connected on a boss on the outer side of the crankshaft box, the surface of the air cylinder is provided with cooling fins, and an inner hole of the boss is in a square shape. The external-connection air cylinder can directly exchange heat with external environment, thereby improving radiating speed of the air cylinder and guaranteeing radiating effects. Simultaneously, the inner structure of the crankshaft box is relatively simplified, thereby being low in production cost, easy to manufacture and assemble and capable of greatly prolonging service life of the compressor and guaranteeing using effects.
Description
Technical field
The utility model relates to a kind of piston type air compressor, and particularly a kind of no oily piston air compressor belongs to the air-pressure equipment field.
Background technique
At present, in the no oily piston air compressor commonly used, often place cylinder crankcase inner, like this, shortened the length of connecting rod on the one hand, saved material, practiced thrift cost, also corresponding the reducing of vibrations during compressor operating; On the other hand, the smaller volume of whole compressor, compact structure is easy to carrying.Less in some spaces, needing roving environment to use down has certain advantage.Though its advantage is outstanding, has also brought some drawbacks.Receive the restriction of crankcase inner space, place the inner cylinder outer surface of crankcase can't increase radiated rib, or increase radiated rib reluctantly; The heat that produces in the cylinder operation yet will just can distribute through crankcase, like this, and during compressor operating; Cylinder is remaining higher temperature, and this higher temperature not only makes delivery temperature raise; Increase consumption of compressor, and be easy to make the distortion of fluoroplastic piston ring, even damage; Influence the working life of compressor, compressor is produced fatal influence, bring very big inconvenience for use and later maintenance.Simultaneously, the crankcase of built-in cylinder, complex structure, course of working is loaded down with trivial details, has also improved processing cost greatly, impacts for sale and popularization.
How to this present situation,, just become the problem that the utility model will solve to existing compressor arrangement improve using effect and service property (quality).
Summary of the invention
In view of the problem that above-mentioned existing technology exists, the utility model aims to provide a kind of simple in structure, processing and easy to assembly, good heat dissipation, the nothing oil piston air compressor that power consumption is little.
The utility model is realized through following technological scheme:
Do not have oily piston air compressor, mainly comprise electric control system, drive part, compression main frame and cooling system, the compression main frame comprises crankcase and cylinder, and cylinder is connected on the boss in the crankcase outside, and being shaped as of boss endoporus is square.
Said cylinder surface also is provided with radiated rib.
The described no oily piston air compressor of the utility model adopts external mode, cylinder is connected on the outside boss of crankcase; And at the cylinder surface exposed part fin is set, directly and external environment condition carry out heat exchange, improved the heat dissipation rate of cylinder; Guaranteed radiating effect; It is bad to have avoided cylinder before to be positioned at the radiating effect that crankcase brings, bigger to crankcase temperature effect, drawback that power consumption is serious.Simultaneously, internal structure is simplified relatively in the crankcase working process, is easy to processing and assembling, and cost of production is low, good heat dissipation effect, and the crankcase power consumption reduces greatly, has prolonged the working life of compressor greatly, has guaranteed using effect.
Description of drawings
Fig. 1 is the assembly structure schematic representation of said crankcase of the utility model and cylinder.
Embodiment
Do further description below in conjunction with 1 pair of the utility model of accompanying drawing:
The said no oily piston air compressor of the utility model mainly comprises electric control system, drive part, compression main frame and cooling system.Wherein, the compression main frame mainly comprises crankcase 2 and cylinder 1, and cylinder 1 is connected on the boss 5 in crankcase 2 outsides through connecting bolt 3, and the endoporus of boss 5 is shaped as square, and boss 5 is highly lower, the space outerpace that takies with reduction.For further increasing the radiating effect of cylinder 1, also be provided with radiated rib 4 in the place of cylinder 1 surface exposure, radiated rib 4 directly and external environment condition carry out heat exchange, can not bring influence to the temperature of crankcase 2.Bent axle in the crankcase 2 is connected through the piston with cylinder 1, drives the continuous to-and-fro motion of piston, finally produces pressurized air.
Claims (2)
1. there is not oily piston air compressor; Mainly comprise electric control system, drive part, compression main frame and cooling system, said compression main frame comprises crankcase and cylinder, it is characterized in that; Said cylinder is connected on the boss in the crankcase outside, and being shaped as of boss endoporus is square.
2. no oily piston air compressor according to claim 1 is characterized in that said cylinder surface also is provided with radiated rib.
