The paint spray can is not sealed, how does it spray paint? How does it work? 30

The high and low water level creates a pressure difference, and the high in the pot makes the pressure make the water spray out. It also uses the principle of pressure, in the case of a certain pressure, the smaller the area, the greater the pressure, and the farther the spray, so the nozzle of the watering can is composed of many small eyes.

In addition, the principle of pressure balancing is utilized. The top of the watering can always has zd1 to multiple vents, which allow air to enter and thus reach the inner and outer atmospheric pressure.

If there is no vent, the water is not poured out.

The nozzle is large or small according to the viscosity of the paint, and the arc can also be adjusted according to the size of the workpiece. Of course, these triggers, nozzles, and arc adjustment switches are sealed.

The gas passes through the small mouth at high speed, and then suddenly amplifies, and then the small mouth generates negative pressure and sucks up the paint. (Why doesn't a high-speed train keep you standing too tight.) Go back, you suck in the same) can be Chaventuri or water jet the same principle.

Dear, hello, I am glad to answer for you 1, the height of the water beam produces a pressure mold, the height of the pot, the pressure makes the water spray out. 2. It also uses the principle of pressure, in the case of a certain pressure, the smaller the area, the greater the pressure, the farther the spray, so the nozzle of the watering can is composed of many small eyes. 3. In addition, it also uses the principle of pressure balance.

There are always 1 to more vents at the top of the watering can, which is to allow air to enter and achieve a balance between the inner and outer atmospheric pressure, and if there is no vent, the water cannot be poured out.

Summary. Hello dear. The lower pot spray gun uses atmospheric pressure to create a local vacuum and suck up the paint.

Hello dear. The lower pot spray gun uses atmospheric pressure to create a local vacuum and suck up the paint.

What is the principle of paint spray gun 1, suction spray gun This spray gun working principle is to use high-speed air flow to make the spray gun locally reach a vacuum, through the pressure generated can suck the paint from the pot to the nozzle, through atomization and spray out, this principle works very well, and well meets the requirements of the thickness of the paint film. 2. The gravity spray gun gravity scale is to use gravity to lead the paint down from the pot to the nozzle, and then spray it out after the paint is atomized by the wind. 3. Press-fed spray gun: Pressurized spray gun needs to be equipped with a paint pressurized tank, and the paint in the pressurized tank can supply paint to several spray guns at the same time under the action of pressure.

This pressure feed spray gun is the opposite of the gravity rubber spray gun, and it is suitable for high-volume, continuous operation.

How to use a paint spray gun 1, first of all, the newly bought spray gun is generally coated with antiseptic oil, and we must clean it with soapy water first. 2. Shake the paint evenly and pour it into the paint cup, and cover the lid as soon as possible after the paint is completely dripped into the paint cup during the process to prevent the paint from decomposing or drying. 3. When spraying paint, first test whether the traces of spraying are normal on the waste material, and start spraying after normal, and the spray gun should be 12-20 cm away from the sprayed surface.

4. The spray gun should always maintain a perpendicular angle with the sprayed surface, keep an equal distance, and move in parallel. Each spray mark should overlap by one-third of the previous one. 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 or over-coating of the local coating.
