查询词典 centrifugal

The process of vapor pressure reducing was achieved through decompression valve and throttling disk. Centrifugal nozzles were installed along the circumference to makewater sprayed more uniform and atomization effect better. The atomization could be optimized and heat transfer between water and vapor was intensified in Ventri. The airproofed-baffle and the holes at the outlet of mixed-pipe, prevented droplet with bigger diameter from entering the turbine, and thus protected the vanes.
