- In detail
The TsNR 500-115-1 — pump are intended for creation of circulation in the closed contour of cooling and purification of blowing-off water of the main contour of the steam generator of blocks of the NPP with the RBMK reactor with a temperature from 15 to 284 °C and with a density from 750 to 1000 kg/m3. The pump — centrifugal, horizontal with the driving wheel of a double entrance with a ring supply and the combined branch. As support of a rotor serve basic and basic and persistent rolling bearings with ring greasing. Trailer consolidation of a shaft represents unary face consolidation with a pulse equilibration of an axial and mobile element. The cooling system consists of a thermobarrier and a circulating contour with the external heat exchanger. The drive — from the asynchronous engine via the vtulochno-manual coupling. A pump housing welded and shod with the entrance and pressure head branch pipes executed under welding to pipelines.
Materials of the main details: a pump housing — steel 12X18H10T or 08X18H10T, pro-rates, a cover and a nut of the main socket — steel 12X18H10T, the driving wheel — steel 20H13L, a shaft — steel 14X17H2, a hairpin of the main socket — steel 10H11N20TZR.
