What is the working principle of Cordless spray paint gun

Cordless spray paint gun is an electric tool that sprays various low-viscosity liquids into mist. The armature is driven by an electromagnet, which acts on the piston rod to perform high-speed reciprocating motion, forming an air suction phenomenon, so that the liquid is sucked up from the container. At the same time, high pressure is formed, which is sprayed out by the nozzle at high speed, atomized, and attached to the surface of the object to complete the spraying process.

How to use the Cordless spray paint gun

1. First of all, the newly bought spray guns are generally coated with anti-corrosion oil. We need to clean them with soapy water first.

2. Shake the paint well and pour it into the paint cup. During the process, let the paint drip into the paint cup completely and cover the lid as soon as possible to prevent the paint from decomposing or drying out.

3. When spraying paint, first test whether the traces of spraying on the waste are normal, and then start spraying, and the spray gun should be 12-20 cm away from the surface to be sprayed.

4. The spray gun should always maintain a vertical angle to the surface to be sprayed, keep an equal distance, and move in parallel. Each spray mark should overlap the last one by one-third.

5. The speed of the spray gun should be appropriate, not too fast or too slow. The speed of application from top to bottom should be too fast to avoid paint build-up and sloppy or localized excessive coating.

Cordless spray paint gun maintenance method

1. Keep the tools intact and clean. The air vent is unblocked, and the tool is filled with lubricating oil in time.

2. Frequently check the power cord and power plug: check whether the switch is in good condition. If there is a malfunction or a damaged part, please have it repaired or replaced by qualified personnel.

3. After the tool is used, it must be maintained in time. After the plastic shell is dirty, it can be wiped with a soft cloth. Do not use solvents, such as gasoline, alcohol, carbon tetrachloride, ammonia water, etc., which will damage the plastic parts.

4. Do not let the power cord come into contact with heat source and grease. Prevent the power cord from being scratched, cut and rolled.

5. After each use of the spray gun, the cylinder and piston rod must be cleaned.

6. After cleaning, drop a small amount of engine oil into the piston to lubricate the internal parts.

7. If for some reason, you forget to clean the spray gun. The next time you use it, you will find the piston rod stuck in the gun body. There will be a buzzing sound after the power is turned on. At this time, the power should be cut off, the pump should be disassembled, and the spray gun body should be soaked in a suitable diluent until the piston rod can move freely. Do not allow the entire spray gun to be submerged in solvent. Solenoids and switches must not allow water or solvents to enter.
