How to use and adjust automatic spray gun

Everyone knows that in the spraying industry, paint spray guns are the most frequently used, but most people may not know much about automatic spray guns. In fact, the automatic spray gun has become an automatic atomizing nozzle. Due to its shape characteristics, it is called an automatic spray gun from a professional point of view. Today, let's first learn about the use of automatic spray guns and their adjustment methods. First of all, when using the automatic spray gun, you need to pay attention to the following points:
1. Ensure adequate air
It is necessary to choose a compressor with sufficient gas production and a suitable air storage tank, because the diameter of the automatic spray gun of the compressed air pipeline is the key to obtaining sufficient compressed air.
2. Control the flow of paint
Adjust the flow according to the paint viscosity and requirements, usually the paint flow control knob is fully open.
3. Control the spraying speed
Due to the different spray gun models, paint viscosity, air pressure, spray width, and spray distance requirements, the spray speed is also different.
4. Maintenance of nozzle set
When replacing the automatic spray gun nozzle set, you should choose a set of the same model as the spray gun. Only genuine parts guarantee the highest quality and longevity.
5. Correctly adjust the inlet pressure of compressed air at the tail of the gun
6. Control the distance of spraying
In order to avoid over-range spraying and poor spraying effect, the best spraying distance for automatic spray guns is generally 20cm.
7. Spraying angle
When spraying, the spray gun and the workpiece should be kept at 90 degrees, that is, the workpiece and the spray gun needle should be kept at 90 degrees vertical.
8. Automatic spray gun flow adjustment knob
The spray width control knob is used for stepless adjustment of the spray width. Turn left to increase the spray width. Turn right to adjust the spray width.
9. Cleaning after use
The spray gun must be cleaned in time after each use. Do not immerse the spray gun in the thinner material for a long time, which will cause the sealing ring of the spray gun to age and cause damage to the spray gun. At the same time, attention should be paid to the disassembly and assembly sequence of the nozzle. The thimble should be disassembled first, then the air vent, and finally the nozzle. Install in reverse order. After cleaning, add an appropriate amount of special lubricating oil for the spray gun to the active parts of the spray gun.
Secondly, the adjustment of the automatic spray gun mainly points out the adjustment of the air volume and the paint volume, which are two interrelated main factors. If the air output is too small, it is not easy to atomize the paint liquid, and the paint liquid will be scattered in droplets, which will make the coating film uneven. The size of the paint output corresponds to the size of the air output. Before spraying, it is necessary to adjust the appropriate air output and the corresponding paint output, so that the paint liquid is well atomized and sprayed evenly on the surface. The important parameters of automatic spray gun can be divided into air pressure, spray width, spraying distance, moving speed and other parts: the air pressure of spraying is generally (0.4--0.6Mpa); the width of spraying on the working surface is about 10cm; When spraying, the distance between the gun nozzle and the object to be sprayed is 15--20cm; the moving speed of the spray gun is generally 30--60cm/sec and so on.
