ROTARY TYPE ELECTROSTATIC SPRAY PAINTING DEVICE

摘要

A ROTARY TYPE ELECTROSTATIC SPRAY PAINTING DEVICE A rotary type electrostatic spray painting device comprising a rotary shaft which is supported by static pressure air bearings in a non-contact state. A drive turbine wheel and a braking turbine wheel are fixed to the rotary shaft. The static pressure air bearings are connected to an air feed pump via an air supply conduit. Pressurized air is injected from air injection nozzles towards the turbine wheels only when the pressure or the flow rate of pressurized air flowing within the air supply conduit exceeds a predetermined level.
