There are many kinds of Spray Gun, but according to the supply of paint to distinguish, the use of more suction type, gravity type and pressure type three.
Suction spray gun The advantage of suction spray gun is that the operation stability is good and the paint color is easy to change. This type of spray gun is more suitable for the manual spraying of steel drums. There is a paint storage tank under this spray gun, which can be unloaded when it is used for steel barrel spraying. The oil-resistant plastic pipe with a length of less than 1m is set on the paint tube (if the length is greater than 1m, the negative pressure of paint absorption may not be enough), and then the hose is inserted into the prepared paint barrel (the position of the paint barrel is better than the height of the spray gun during construction, so as to strengthen the paint absorption capacity). This allows continuous spraying of steel drums without the need to add paint to the storage tank over and over again.
The disadvantage of this spray gun is that when the spray gun comes with the paint can spraying, the horizontal plane (such as manual spraying the bottom and cover of the steel barrel standing) is more difficult, and because of the small capacity of the paint can, it is necessary to constantly add material to the tank, and when the viscosity of the paint is different at the same time, the amount of spray changes.
Gravity spray gun The Angle of the paint cup can be adjusted freely. Although the paint cup can be removed and the lacquer pot placed high is connected to it with a hose, its paint flow rate is too small and its stability is poor, so this kind of spray gun is most suitable for laboratory multi-color sample spraying.
Pressure feed spray gun Compression type gun is actually on its feet high pressure spray gun, its characteristic is to rely on pressure paint, can supply automatic spray gun coating can be sprayed high viscosity of paint, and paint uniform fine. Due to the paint fog without air flow, so the formation of the film quality is better, it's not easy paint flying like perfume spray gun. It is not limited by the direction of the spray paint, all directions of the sprayed surface can be sprayed to.
