Most spray guns are standard especially manual spray guns, follow the attach user manual for your installation and operations that will do.

But for the electrostatic rotary bell bit complicated, there more than 4-5 connections for the bell gun,  they are air flow, rotating speed, air pressure, paint input, and optical fiber connections etc.

Thin liquid films on a rotary bell atomizer in surface- following coordinates.

The thickness of a paint film on a high-speed rotary bell,1 especially near the periphery,2 has significance because film thickness in the region of departure contributes to the determination of average drop diameter in the subsequent spray.3 An example of an automotive New energy parts painting process, from supplied liquid through film deposition, is schematically shown in Fig. 1. As paint, which is a system of solvents and solutes, departs from the bell, it is shredded4 into an“infinity”of drops that can be approximated by a statistical distribution.5 Aerodynamic forces have a dependency on the initial tangential velocity of the departing drops. Thus, the eventual average drop diameter is influenced by a tentative balance between complex aerodynamic drop-shredding forces, drop-preserving forces of surface tension, and, if present, electrostatic forces.6 Larger drops are more vulnerable to aerodynamic shredding. However, as shredding reduces drop diameter, surface tension forces become relatively dominant, limiting further drop breakup.

Process flow—liquid paint enters the center of the bell, shear forces spread the liquid over the concave bell surface and accelerate it to the edge where it is atomized, and finally, air currents and electrostatics propel droplets toward deposition on the coating work-piece

Electrostatic rotary bell control cabinet

Main configuration: the paint supply and spraying control part is composed of pneumatic control cabinet, color change valve, gear pump and motor, electrostatic spraying rotating bell switch, paint, solvent and air supply pipeline, flow, atomization pressure, forming air pressure and high voltage conditioning system,
