Friends often ask: The spray gun is obviously not blocked, but there is no paint coming out. What is going on?
If the spray gun can't spray paint, we ruled out the cause of the spray gun clogging, and then we need to divide the manual spray gun and the automatic spray gun.
Manual spray gun
This situation usually occurs with the lower pot (suction-up type) spray gun, and the upper pot (gravity type) and pressure-feed spray guns will not have this situation. The lower pot spray gun relies on the siphon of the spray gun to supply oil, so the reason for this is that the siphon effect is destroyed.
1. We need to observe whether the paint can is screwed or sealed well with the spray gun.
2. Whether the needle and nozzle of the gun have been disassembled, if necessary, reconfirm the tightening of the nozzle.
3. There is a spray gun tightening between the wrench and the gun head. There is also a leak. You can tighten the tightening screw appropriately to see if the oil can be discharged. If it still does not work, you need to replace the tightening kit.
