In the actual application process of the spraying system, many people do not pay much attention to the 
speed of the spray gun pipeline. They want to take the equipment back. It seems that it is simple to 
connect the air pipe to the pipeline and it can be used.

In fact, this is not the case. If you did not notice this in the process of developing the spray system, it 
would easily cause a series of problems. For example, the spray gun does not produce paint, the spray 
gun does not produce air, etc., which directly reflect the problems on the spray gun. Some are 
completely unresponsive.

So these are basically the results of not paying attention to the pipelines of our spraying system. How 
should the automatic spraying system layout the pipelines so as not to cause problems?

In the automatic spraying system, the reciprocating machine is equipped with 4 spray guns, and the basic 
configuration is a set of 4 separation membrane pumps for oil supply and a set of 5 gallon agitators.

First of all, let's look at the oil circuit, choose 8MM in charge and 6MM in charge. For the spray gun here, 
we take the WA-101 caliber 1.0MM (the spray guns of different models and calibers are slightly different).

It should be noted here that whether it is the gas circuit or the oil circuit, it is better to have a larger main 
pipe, so as to ensure that the amount of oil or gas is sufficient. The oil circuit is relatively simple. The 
supervisor passes the first spray gun, then returns the oil to the second spray gun, and so on until the last 
returns the oil into the paint bucket.

The trachea is a little more complicated, but remember that you can’t go wrong. The needle must not be 
strung with the atomizer, that is, the CYL hole on the spray gun should not be strung with the atomizer 
CAP and FAN, otherwise the spray gun will fail to fire. The main reason is that the amount of air consumed 
by the atomization is too large, which will reduce the air pressure of the firing needle, causing the 
phenomenon that the spray gun cannot be opened. Therefore, it is best to divide into two supervisors or 
three supervisors (with spray gun imported from FAN). In this way, each gas path can be controlled 
independently.

In addition, the last point to be emphasized is that the advanced solenoid valve enters the pressure 
regulating valve and finally enters the spray gun. Do not make a mistake in this sequence. There are 
mistakes in the actual process, mainly because the solenoid valve also has a certain decompression effect. 
The air pressure to the spray gun is not very accurate, so the atomization is very well adjusted.
