When the automatic spray gun sprays paint, does the paint flow slowly decrease?

This happens in many scenarios where automatic spray equipment is used. Is the gun broken or the oil supply system stopped supplying oil? In daily investigations, these two exist relatively rarely.

The main reason is that we chose the wrong caliber of the gun. At this time, some friends will say, what is the relationship between gun oil and caliber, you are irrelevant. Don't worry, just listen to me slowly. Why did you choose the wrong gun caliber? In fact, most of the cases we will encounter are when we adjust the flow rate of the gun very small so that the gap between the needle and nozzle of the gun is very close, and the piston spring relatively large force. If the air pressure weakens or changes direction slightly, the needle will return to its original position, closing the gun, just as water cannot flow out when the ball valve is closed.

So how to fix that? That is to switch to a small bore, because you adjust the flow knob in the gun to get a smaller flow, but with all the tools you can't make it work in a limited range all the time, so it won't Achieving good results, which is why the guns are divided into so many sizes. When a small flow rate is required, a small-bore spray gun should be selected.

Therefore, choosing the right spray gun caliber is also critical for spraying. Therefore, in the process of integrating with the equipment, we must fully understand the production process and specific effect requirements, and then select the best or best accessories according to the requirements.
