Inoshandiswa semidziyo yekuvhura nekuvhara yekupomba system kana imwe yakakwirira uye yepakati kumanikidza pombi masisitimu e600 kusvika 1,000MW supercritical (ultra-supercritical) unit steam turbine.
- Muviri wevharuvhu uye bhoneti inotora yepakati flange yakavharidzirwa yekubatanidza chimiro, ine nyore disassembly. Magumo ese ari maviri anotora welded yekubatanidza.
- Ivhavha disc inotora mhando yekusimudza yakawanda-nhanho yekuvhara chimiro.
- Chigaro chevharuvhu chinotora conical sealing. Iine rigid alloy kuvaka-up welding, iyo yekuisa chisimbiso inoratidzira cavitation uye abrasion kuramba.
- Multi-step cover inogamuchirwa kudzora nhanho imwe neimwe yekumanikidza kudonha kuita throttled pressure control pamusoro pe saturation pressure kuderedza kuitika kwe cavitation uye flash evaporation.
- Iine inoshanduka sarudzo, iyo actuator inopihwa nevhavha inogona kugadzirwa sekuenderana nezvinodiwa nevashandisi.
