Primarily divided into air spray guns, high-pressure airless spray guns, air-assisted airless spray equipment, low-flow medium-pressure spray equipment, airless spray guns, low-pressure spray guns, and electrostatic spray guns. Categorized by performance: plunger-type, fuel-type, trolley-type, pneumatic, electric, and plunger-diaphragm composite. Classified by manufacturing principle: plunger spray guns and plunger-diaphragm composite spray guns. Spray guns are mainly composed of feeding devices, spray heads, and atomization sources. The atomization sources vary depending on the type of spray gun.


How to Install an Oil Pipeline Painting Machine

An oil pipeline painting machine is a device used for painting oil pipelines, and its installation process involves the following steps:
Preparation: First, ensure you have all the necessary tools and materials ready, including a paint sprayer, pipes, paint cans, spray guns, and paint.
2. Install the Paint Spraying Machine: Place the paint sprayer in an appropriate location, identify the best spraying equipment, then connect the power and gas sources, and check if the equipment is functioning properly.
3. Pipe Installation: Connect the pipe to the paint sprayer, specify the spray equipment pricing, and ensure the pipe joints are tightly sealed with no air leaks.
4. Adjust Spray: Adjust the nozzle size and paint spray distance as needed to achieve the best paint spray effect.
5. Spray Painting: Pour the paint into the spray gun, then turn on the spray machine and spray, beginning the painting process on the pipeline.
6. Clean-up: After painting, it is necessary to promptly clean the spray gun and the paint sprayer to prevent paint from clogging the spray gun or the sprayer.
When installing the oil pipeline painting machine, the following points should be noted:
The installation location should be chosen in a well-ventilated and dry area to prevent the equipment from getting damp or overheating.
Ensure the pipe connections are tight and leak-free when joining pipes to prevent paint leakage.
3. Adjust the spray during application based on the size and shape of the pipe to achieve the best paint finishing effect.
4. Keep the spray gun and paint sprayer clean during painting to prevent paint clogs in the gun or sprayer.
5. Use appropriate cleaning agents and tools during cleaning to ensure the equipment remains clean and intact.

The main working part of the spray gun is a double-acting pneumatic hydraulic booster pump, with a directional change mechanism consisting of a special form of pilot-assisted fully pneumatic valve actuation device. After compressed air is introduced, the performance of the spray equipment depends on whether the piston moves to the top or bottom of the cylinder. In Suzhou, the spray equipment activates the upper or lower pilot valve, controlling the air flow to instantaneously shift the valve actuation device, thereby enabling the piston of the pneumatic motor to perform a stable and continuous reciprocating motion. This is due to the rigid connection between the piston and the plunger in the paint column pump, and also because the piston area is larger than the plunger area.
