High swirl air cap

摘要

The present disclosure relates generally to spray systems and, more particularly, to industrial spray coating systems for applying coatings of paint, stain, and the like. Specifically, the disclosed embodiments relate to a spray gun an air cap configured to produce air swirl. For example, in an embodiment, a system is provided that includes a spray coating device. The spray coating device has a liquid passage extending to a liquid outlet configured to output a liquid flow and an air passage extending to a plurality of air outlets configured to output an air flow. The plurality of air outlets is angled to swirl the air flow.

主权项

1. A system, comprising:
a spray coating device, comprising:
a removable liquid nozzle having a liquid passage extending to a liquid outlet configured to output a liquid flow; anda removable air cap separate from the removable liquid nozzle, wherein the removable air cap comprises an air passage extending to a plurality of air outlets configured to output an air flow, the plurality of air outlets are disposed in a curved arrangement at least partially around a liquid flow axis of the liquid outlet, the plurality of air outlets is angled inwardly toward the liquid flow axis without intersecting the liquid flow axis, the plurality of air outlets is angled to swirl the air flow, the plurality of air outlets comprises a first plurality of air outlets configured to swirl the air flow in a first rotational direction about the liquid flow axis, the plurality of air outlets comprises a second plurality of air outlets configured to swirl the air flow in a second rotational direction about the liquid flow axis opposite from the first rotational direction, and at least some of the plurality of air outlets are configured to output the airflow to facilitate atomization of the liquid flow output from the liquid outlet.
