How to adjust the three knobs on the spray gun?

The knob near the pipe joint at the bottom of the spray gun is used to adjust the compressed air flow, the knob in the middle is used to adjust the paint amount, and the knob at the top is used to adjust the fan surface.

Paint spray gun is mainly composed of nozzle, nozzle, needle valve and gun body. At the same time, external air pressure devices, such as pressure tanks, pressure barrels, pumps, etc., are needed.

According to the use type, it can be divided into manual spray gun, automatic spray gun and manual spray gun, and manual spray gun can be further classified. The classification of manual spray guns is mainly based on different working principles, such as gravity type, pressure type and suction type.

Extended data:

First, the advantages of electrostatic spray gun:

1, electrostatic spray gun is a new product based on the improvement of traditional high-pressure air spray gun and the application of advanced technology theory. Simple operation, good atomization effect, safer and more paint-saving.

2. electrostatic spray gun has one more electrostatic generator than a high-pressure air spray gun, which will generate positive or negative charges, and the voltage is higher, generally more than tens of kilovolts, but the current is very small.

3. The condition of electrostatic spray gun spraying is that the coating has certain conductivity, and the coated workpiece also has conductivity, thus giving play to the electrostatic effect and advantages.

4. electrostatic spray gun is designed according to the physical principle of opposites attract, so compared with the traditional high-pressure air gun, it saves fuel and improves painting efficiency.

Second, the paint spray gun maintenance:

1. Before and after each tool use, inject 3-4 drops of special pneumatic maintenance oil from the tool inlet to reduce wear and prolong the service life of the tool.

2. Ensure that the air source of the supply tools is dry and free of impurities.

3, regular cleaning, refueling maintenance, timely replacement of worn parts.
