1) Y-patani yakaumbwa muviri, kushoma kuyerera kuramba, yakakwira CV kukosha.
2) Dhisiki rine throttle chidimbu, zvinobudirira kudzivirira chisimbiso pamusoro, kuwedzera vharafu upenyu.
3) Dhisiki & chigaro chisimbiso chepamusoro chinobatwa nekugadziriswa kwakakosha kwe-anti-cavitation, anti-erosion.
4) Mhete mbiri dzinotungamira mu diski dzinoita kuti stem bere kuenzanisa simba, kuchinjika kufamba kudzivirira jammed chiitiko.
5) Yepamusoro-soro inoshanduka graphite kurongedza GARLOCK inotengeswa kunze kwenyika, yakanaka makemikari pfuma uye kuchinjika, kuderera kwakadzika, hupenyu hurefu hwebasa.
6) Kurumidza kushandura kumhanya, kazhinji 3-5 masekondi, zvino chengetedza kuchengetedza system, kuderedza zvakanyanya nguva yekuvharwa kwechisimbiso yakanyungudika nevezvenhau.
7) Bonnet heatsink, kutonhora kwakakwana kuchengetedza pneumatic actuators uye solenoid valve isina kukanganiswa nekupisa kwakanyanya. Chamber gasket clip waya iyo yakakwira mesh inochinjika graphite pad, iri nani yekuisa chisimbiso uye kuvimbika kupfuura avhareji inoshanduka graphite.
Pneumatic steam drain mavharuvhu nzvimbo yakaiswa mumhepo pombi yemagetsi emagetsi emagetsi, ayo anogona kupatsanurwa zvinoenderana nenzvimbo yekukwira se:
·Main steam line mavharuvhu
·Hot reheat line drain mavharuvhu
· Cold reheat line drain valves
· Danho rekutanga, danho rechipiri, rechitatu, danho rechina, nhanho yechishanu uye yechitanhatu yekubvisa mavharuvhu
