Spray gun is a key equipment in the spraying process system. Although different spray guns have many common parts, each type or model of spray gun is only suitable for a certain range of operations. Choosing the right tools is the guarantee for completing high-quality assignments in the shortest possible time.
\nA spray gun consists of a gun body and a spray gun nozzle. The gun body is divided into air valve, paint flow control valve, oil mist control valve (i.e. paint mist fan-shaped angle adjustment), paint control valve, compressed air intake valve, trigger, handle, etc. The spray gun consists of an air cap, paint nozzle, and ejector pin.
\nThe performance of a spray gun depends on the relationship between the amount of paint sprayed and the air consumption. When the amount of paint sprayed is small and the air consumption is high, the coating particles are small, while when the amount of paint sprayed is large and the air consumption is low, the coating effect is poor. The spraying volume of a small spray gun is generally 10-200ml\/min, while that of a large spray gun is 120-600mL\/min. The spraying volume of air for a small spray gun is 40-290 l\/min, while that for a large spray gun is 280-520L\/min. The larger the amount of paint sprayed, the greater the amount of air used.<\/p>\n
Types of commonly used spray guns
\nThere are various types of spray guns with different purposes. According to the supply methods of coatings, there are mainly three types: gravity based, siphon based, and pressure based.
\nAt present, automobile repair shops commonly use gravity spray guns and siphon spray guns. Siphon spray guns are highly favored by painters due to their easy operation.
\nThe main reason why siphon spray guns are popular is that they can operate continuously in large-scale spraying, thereby improving construction efficiency. The spray valve can be adjusted from round to sector, and the spray section can be adjusted within 360 degrees. When the nozzle side air hole is in a horizontal position with the main air hole, the airflow from the left and right air holes compresses the paint mist from the main air hole into a vertical fan-shaped paint mist shape, which can be used for horizontal movement spraying of side objects. When the air hole on the side of the nozzle is perpendicular to the main air hole, the paint mist sprayed from the center hole forms a horizontal fan-shaped paint mist, which can be used for vertical up and down spraying of objects on the side.<\/p>\n","protected":false},"excerpt":{"rendered":"
