[0002] A pressure vessel refers to a closed device that contains gas or liquid and bears a certain pressure. Pressure vessels usually contain high-pressure or high-temperature media, which are often corrosive. If the surface of the pressure vessel is not properly treated with corrosion protection, the container wall will be corroded, which will in turn affect the strength and sealing of the container. In severe cases, it may even cause the container to rupture or leak, causing a safety accident. The method of corrosion protection for pressure vessels is usually to coat the surface of the container with a layer of anti-corrosion coating, such as epoxy coating, polyurethane coating and chloroprene rubber coating, to protect the container surface from corrosion.

[0003] The shortcomings of the existing technology: In the existing spraying technology, most of them use a manual handheld brush to paint the outer surface of the pressure vessel. However, during the painting process, the staff maintains the same brushing posture for a long time to paint the outer surface of the pressure vessel, which may cause soreness in the limbs of the staff, resulting in a decrease in the efficiency of the pressure vessel painting work, further reducing productivity, reducing the practicality of the equipment, and being unfavorable for actual application and operation.
