A kind of steam-operating type high pressure airless spraying apparatus
Technical field
The utility model relates to a kind of spraying equipment, is specifically related to a kind of high pressure airless spraying apparatus.
Background technology
Airless spraying is to carry coating by the high-pressure pump in closed container, makes coating under high pressure spray atomization, and need not be by the technique of compressed air atomization.The principle of airless spraying is to coating high-pressure, it is sprayed from paint spray nozzle, with the speed up to 100m/s and air, there is fierce collision, make coating be broken into particulate, while die-offing due to pressure, coating internal solvent sharply volatilizees, and volume expands suddenly, and coating atomization also sticks to coated article surface.But when operation, equipment can produce unsteadyly, and was difficult for regulating, therefore spray unstablely, be not suitable for the decorative painting of thin layer, and cause equipment wearing capacity large.
Utility model content
Utility model object: the purpose of this utility model is in order to overcome the deficiencies in the prior art, provides a kind of and operates steadily, sprays the little steam-operating type high pressure airless spraying apparatus of fluctuation.
Technical scheme: a kind of steam-operating type of the utility model high pressure airless spraying apparatus comprises power source, plunger displacement pump, container for paint, pressure accumulation filter, coating conveyance conduit and spray gun, described power source is connected with described plunger displacement pump, the plunger of described plunger displacement pump extend out in described container for paint, and described plunger displacement pump is connected and is connected with described spray gun by described coating conveyance conduit with described pressure accumulation filter; Plunger the motive power that can provide coating to spray at a high speed drawing coating from container for paint when is provided, coating filters through pressure accumulation filter, reduce paint road and stop up, by coating conveyance conduit, be delivered to spray gun, spray gun is surperficial in coated article by coating atomized spray.
Further, described plunger displacement pump is double action type, when plunger moves up and down, all can export coating, operates steadily, coating pressure fluctuation is little, and parts wear is little.
Further, described coating conveyance conduit is that coating resistant corrodes, high voltage bearing flexible pipe.
Further, on described coating conveyance conduit, pressure-reducing valve is set, pressure-reducing valve capable of regulating air pressure is controlled the output pressure of coating.
Beneficial effect: the utility model operates steadily when spraying, and coating pressure fluctuation is little, parts wear is little; Spraying stable and uniform, can control spray pressure, therefore also can be used for slim ornamental spraying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
embodiment:a kind of steam-operating type high pressure airless spraying apparatus, comprise power source 1, plunger displacement pump 2, container for paint 3, pressure accumulation filter 4, coating conveyance conduit 5 and spray gun 6, power source 1 is connected with plunger displacement pump 2, plunger displacement pump 2 is double action type, the plunger of plunger displacement pump 2 extend out in container for paint 3, plunger displacement pump 2 connects pressure accumulation filter 4, and pressure accumulation filter 4 is connected with spray gun 6 by coating conveyance conduit 5, and pressure-reducing valve 7 is set on coating conveyance conduit 5.
When moving up and down, plunger all can from container for paint 3, draw coating, the motive power that simultaneously provides coating to spray at a high speed, coating filters through pressure accumulation filter 4, reducing paint road stops up, by coating conveyance conduit 5, be delivered to spray gun 6, pressure-reducing valve 7 capable of regulating air pressures are controlled the output pressure of coating, and spray gun 6 is surperficial in coated article by coating atomized spray.
As mentioned above, although represented and explained the utility model with reference to specific preferred embodiment, it shall not be construed as the restriction to the utility model self.Not departing under the spirit and scope prerequisite of the present utility model of claims definition, can make in the form and details various variations to it.
