Rotary bell applicators are essential technology in industrial painting, with each part of the device playing a critical role in the paint application process. This article will introduce you to the main components of the rotary bell and their functions, which are crucial for achieving consistent and efficient results.
The bell cup is at the heart of the paint atomization process. It spins at speeds of tens of thousands of RPMs to atomize the paint, breaking it down into fine particles for even application.
The splash plate evenly spreads the paint inside the bell cup before atomization. This ensures a consistent flow and prevents uneven application.
The air shaping ring, which includes the air cap and cover, guides the shaping air to achieve the right diameter for the spray pattern from the bell cup. This component defines the width and uniformity of the spray.
The fluid delivery system, which includes a fluid tube and nozzle, directs paint or solvent to the bell cup assembly, ensuring a steady supply for the atomization process.
The air turbine assembly, powered by compressed air, drives the bell cup at high speeds, reaching tens of thousands of RPMs. This rotation is critical for consistent paint atomization.
The electrostatic charging system enhances paint adhesion and coverage by charging the paint particles. This boosts transfer efficiency, attracting paint to grounded surfaces and reducing overspray.
With regular maintenance and understanding of each component’s role, you can achieve better performance, efficiency, and quality in the paint application process.
