Munguva yenguva dzose yekushanda kwepamusoro-pressure heater ye600 kusvika 1,000MW supercritical (ultra-supercritical) thermal power unit, nzira huru yevhavha yenzira nhatu pamhepo inopisa inopisa inozaruka uye nzira yekudarika yakavharwa. Mvura yebhailer inopinda mu-high-pressure heater kubva kunzira huru isati yapinda mubhailer kuburikidza nevhavha yenzira nhatu pane yakakwirira yekupisa heater.
- Muviri wevharuvhu nebhoneti zvinotora chimiro chesimbi chakanyatsogadzirwa.
- Chisimbiso mhando yemuviri wevharuvhu uye bhoneti inotora kudzvanywa kwekuzvivharira chimiro.
- Pamusoro pebhoneti yevharuvhu pane jekiseni remvura uye maburi emvura uye piston inovakwa mubhoneti revharuvhu.
- Kuisa chisimbiso chechigaro chevharuvhu uye disc kunotora Stellite No. 6 alloy spray welding.
- Iyo bypass yekuisa chisimbiso inotora chisimbiso chimiro chekubatanidza yakagadziridzwa PTFE elastic simba rekuchengetedza mhete uye perfluoro O-ring.
- Zvinhu zvinopinza mukati memukati-nzira nhatu vharafu bypass uye chigaro chepamusoro chevharuvhu chinotora dhizaini yakabatanidzwa uye haidi imwe throttle orifice zvakasiyana.
