Kumvetsetsa Ma Compressor a Mlengalenga a Centrifugal

Ma compressor a mpweya wa centrifugalZimayendetsedwa ndi ma impeller kuti azizungulira mofulumira kwambiri, kotero kuti mpweya umapanga mphamvu ya centrifugal. Chifukwa cha kufutukuka ndi kuthamanga kwa mpweya mu impeller, kuchuluka kwa kuyenda ndi kupanikizika kwa mpweya pambuyo podutsa mu impeller kumawonjezeka, ndipo mpweya wopanikizika umapangidwa mosalekeza.
Mawonekedwe
Ma compressor a mpweya wa centrifugal ndi ma compressor othamanga. Pamene mafuta ali okhazikika, ma compressor a mpweya wa centrifugal amagwira ntchito mokhazikika komanso modalirika.
①Kapangidwe kakang'ono, kulemera kopepuka, kuchuluka kwakukulu kwa utsi;
②Zida zovalidwa zochepa, ntchito yodalirika, komanso moyo wautali;
③Utsi wotuluka sunadetsedwe ndi mafuta odzola, ndipo mpweya wabwino ndi wapamwamba;
④Kugwira ntchito bwino komanso kusunga mphamvu pamene malo osungiramo zinthu ali ambiri.
Mfundo yogwirira ntchito
Ma compressor a mpweya wa centrifugalZimakhala ndi magawo awiri makamaka: rotor ndi stator. Rotor ili ndi impeller ndi shaft. Pali masamba pa impeller, komanso balance disc ndi gawo la shaft seal. Thupi lalikulu la stator ndi casing (cylinder), ndipo stator ilinso ndi diffuser, bend, returner, exhaust payipi, exhaust payipi ndi gawo la shaft seal. Mfundo yogwirira ntchito ya centrifugal compressor ndi yakuti impeller ikazungulira mofulumira kwambiri, mpweya umazungulira nayo. Pogwiritsa ntchito mphamvu ya centrifugal, mpweya umaponyedwa mu diffuser kumbuyo, ndipo vacuum zone imapangidwa pa impeller. Panthawiyi, mpweya watsopano wochokera kunja umalowa mu impeller. Impeller imazungulira mosalekeza, ndipo mpweya umalowetsedwa ndikutulutsidwa mosalekeza, motero kusunga kuyenda kosalekeza kwa mpweya.
Ma compressor a mpweya wa Centrifugal amadalira kusintha kwa mphamvu ya kinetic kuti awonjezere kuthamanga kwa mpweya. Rotor yokhala ndi masamba (monga gudumu logwirira ntchito) ikazungulira, masambawo amayendetsa mpweya kuti uzungulire, kusamutsa ntchito kupita ku mpweya, ndikupangitsa kuti mpweya upeze mphamvu ya kinetic. Pambuyo polowa mu gawo la stator, chifukwa cha kukula kwa stator, mutu wa kuthamanga kwa mphamvu ya liwiro umasinthidwa kukhala kuthamanga kofunikira, liwiro limachepetsedwa, ndipo kuthamanga kumawonjezeka. Nthawi yomweyo, mphamvu yotsogolera ya gawo la stator imagwiritsidwa ntchito kulowa mu gawo lotsatira la impeller kuti ipitirize kuwonjezera kuthamanga, ndipo pamapeto pake imatulutsidwa ndi volute. Pa compressor iliyonse, kuti ikwaniritse kuthamanga kofunikira, compressor iliyonse imakhala ndi magawo ndi magawo osiyanasiyana, ndipo imakhala ndi masilinda angapo.
