Water misting gun

摘要: A high-velocity water misting gun with a very high-speed radial inflow hydraulic turbine mounted on the same shaft an axial flow air compressor wheel compressing discharged at high velocities through exhaust nozzle. preferred embodiment utilizes plastic-metal in which plastic portion of other than blades is solidly anchored within metal containing wheel. High pressure drives and provides lubrication to bearings supporting rotating shaft. The hybrid (part hydrodynamic, part hydrostatic) suitable for low-viscosity fluids such as water. In all discharging from channeled hollow set high-speed, shaft-mounted orifices providing fine mist into provided by axial-flow compressor. Thus, entire supplied nozzle so that no return hose needed. Preferred embodiments utilize manually operated ball valve control turbine. Increased power increases input resulting roughly proportional ratio.
