2. Thuso ea Pipeline Setting eaArola Case Pompo

2-1. Phaephe ea pompo e futhumetseng: Ha mocheso oa thepa e fanoang ke pompo ea centrifugal e feta 200 °C, ho hlokahala hore ho kenngoe phala e futhumetseng ea pompo e le hore ho tsamaisoa thepa e nyane ho tloha pompong ea ho tsoa ha pompo ea ts'ebetso ho ea moo ho tsoang teng. pompo ea standby, ebe e phalla ka har'a pompo ea standby, ebe e khutlela seketjaneng sa pompo ho etsa pompo ea standby Pompo e boemong ba standby e chesang hore e ka qala habonolo.

2-2. Liphaephe tse thibelang condensation: DN20 25 liphaephe tse thibelang leqhoa li lokela ho kenngoa bakeng sa lipompo tse nang le condensable medium mocheso o tloaelehileng, 'me mokhoa oa ho beha o tšoana le oa liphaephe tse futhumetseng tsa pompo.

2-3. Pipe e leka-lekaneng: Ha seaplane se sekametse ho keneng ha pompo, phaephe ea ho leka-lekana e ka khutlelang sebakeng sa khase ea thepa e ka holimo ka lehlakoreng la ho huloa e ka kenngoa pakeng tsa molomo oa pompo le valve e koalang. , e le hore khase e hlahisoang e ka phalla morao. E le ho qoba cavitation ea pompo, valve e khaotsoeng e lokela ho kenngoa phala ea tekanyo.

2-4. Phaephe e fokolang ea ho khutlisa: E le ho thibela pompo ea centrifugal ho sebetsa ka tlase ho tekanyo e fokolang ea phallo ea pompo, phala e fokolang ea ho khutlisa ea pompo e lokela ho hlophisoa ho khutlisetsa karolo ea mokelikeli ho tloha boema-kepeng ba ho ntša pompo ho ea setshelo nakong ea karohano. boema-kepe ba ho hula pompo ho netefatsa sekhahla sa phallo ea pompo.

Ka lebaka la ho khetheha ha pompo, hoa hlokahala ho ba le kutloisiso e feletseng ea ts'ebetso ea pompo le lisebelisoa tsa ts'ebetso tse sebetsang ka har'a pompo, 'me tlhophiso e utloahalang ea liphaephe tsa eona tse kenang le tsa ho tsoa lia hlokahala ho netefatsa ts'ebetso ea eona e bolokehileng le e tsitsitseng. .
