Choosing the right spray gun caliber is very important for spraying

This happens in many scenarios where automatic spray equipment is used. Is the spray gun broken or the fuel supply system stops supplying fuel? In daily investigations, these two types are relatively rare.

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

So how to solve it? That is to change to a small caliber, because you adjust the flow knob in the spray gun to get a smaller flow, but you can't make it work in a limited range all the time, so it will not achieve good results. This is why the spray gun is divided into so many specifications. When a small flow rate is required, a small-caliber spray gun should be selected.

Therefore, choosing the right spray gun caliber is also very important 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.
