Pampu ya Centrifugal Impeller

Pampu ndi chipangizo chomwe chimatumiza kapena kukakamiza madzi. Iwo umasamutsa choyambirira mawotchi mphamvu kapena zina kunja mphamvu kwa madzi kuonjezera madzi mphamvu, potero kumaliza madzi kayendedwe. The mpope makamaka ntchito kunyamula zamadzimadzi monga madzi, mafuta, asidi-m'munsi madzi, emulsion, kuyimitsidwa emulsion ndi madzi zitsulo, komanso madzi-gasi osakaniza ndi madzi munali zolimba inaimitsidwa. Pampu imatha kunyamula madziwo ndi madzi ngati sing'anga, koma sangathe kunyamula zolimba.

 

Kugwiritsa ntchito Pampu

M'mafakitale amafuta ndi mafuta, zopangira, zomalizidwa pang'ono ndi zomalizidwa nthawi zambiri zimakhala zamadzimadzi. Kupanga zopangira kukhala zinthu zomalizidwa pang'ono ndi zinthu zomalizidwa kumafuna njira zaukadaulo zovuta, ndipo mapampu amatenga nawo gawo potumiza ndikupereka kukakamizidwa munjira izi. Kuphatikiza apo, mapampu amathanso kugwiritsidwa ntchito m'malo ambiri kuti aziwongolera kutentha.

Popanga ulimi, mapampu ndi makina akuluakulu amthirira. Kupanga kwaulimi kumafuna mapampu ambiri. Nthawi zambiri, mapampu aulimi amapitilira theka la zonse zomwe zimatuluka.

Mapampu ndi zida zomwe zimagwiritsidwanso ntchito kwambiri m'mafakitale amigodi ndi zitsulo. Mgodi uyenera kutsanulidwa ndi mapampu, ndipo pothandizira, kusungunula ndi kugudubuza, pamafunika mapampu kuti apereke madzi.
M'gawo lamagetsi, zopangira magetsi a nyukiliya zimafuna mapampu amitundu yambiri monga mapampu achiwiri ndi mapampu apamwamba. Mafakitale opangira magetsi otenthetsera amafunikira mapampu ambiri opangira boiler, mapampu a condensate, mapampu osakaniza amafuta ndi gasi, mapampu ozungulira ndi mapampu aphulusa.

M'makampani achitetezo, kusintha kwa zipini za ndege, zowongolera mchira ndi zida zotera, kuzungulira kwa zombo zankhondo ndi akasinja akasinja, komanso kukwera ndi kutsika kwa sitima zapamadzi zonse zimafunikira mapampu. Kwa mapampu omwe amatulutsa kuthamanga kwambiri komanso zakumwa zoziziritsa kukhosi, sayenera kutayikira.

Mwachidule, kaya ndi m'minda ya chitetezo cha dziko monga ndege, roketi, akasinja, ndi sitima zapamadzi, kapena m'mafakitale monga kubowola, migodi, sitima zapamadzi, ndi zombo, kapena kupanga tsiku ndi tsiku ndi moyo, mapampu akufunika kulikonse; ndipo mapampu akuyenda paliponse. Ndi motere kuti mpope ndi wa makina ambiri ndipo ndi mtundu wazinthu zazikulu zamakina.

 

Malinga ndi magawo osiyanasiyana, mapampu amatha kugawidwa m'magulu ambiri. Mapampu amatha kugawidwa m'magulu atatu: mapampu abwino osamutsidwa, mapampu amphamvu ndi mitundu ina ya mapampu molingana ndi mfundo zawo zogwirira ntchito. Malinga ndi njira yoyendetsera galimoto, imatha kugawidwa kukhala pampu yamagetsi ndi pampu ya hydraulic; malinga ndi kapangidwe kake, imatha kugawidwa kukhala pampu yagawo limodzi ndi pampu yamagawo angapo; malinga ndi cholinga chake, imatha kugawidwa kukhala pampu yamadzi yotentha ndi pampu yoyezera; Pampu yamadzi, pampu ya condensate, mpope wa phulusa, mpope wamadzi wozungulira, ndi zina zambiri.

Pampu ya centrifugal imatanthawuza pampu yomwe imanyamula madzi ndi mphamvu ya centrifugal yopangidwa ndi kuzungulira kwa madzi.wochititsa. Mapampu a centrifugal amagwira ntchito pozungulira chopondera kuti apangitse kuyenda kwamadzi. Asanayambe mpope, chopondera cha pampu ndi chitoliro choyamwa chiyenera kudzazidwa ndi madzi, ndiyeno injini imayambika, kotero kuti shaft ya pampu imayendetsa chotsitsa ndi madzimadzi kuti azizungulira mofulumira kwambiri mu payipi ya mpope.

The impeller mpope amadalira impeller kuyendetsa madzi azungulire pa liwiro lalikulu ndi kusamutsa mawotchi mphamvu kwa madzi operekedwa. Mitundu yosiyanasiyana ya ma impeller imatha kugawidwa kukhala:
1) Pampu ya centrifugal
2) Pampu ya axial
3) Pampu yosakanikirana
4) Pompu yozungulira

The impeller anaika mupompa pompandi kumangirizidwa ku shaft ya mpope, yomwe imayendetsedwa mwachindunji ndi galimoto. Pali madzi kuyamwa chitoliro pakati papompa pompa. The madzi amalowa mpope kudzera pansi valavu ndi suction chitoliro. Doko lotulutsira madzi pa pompu la pampu limalumikizidwa ndi chitoliro chotulutsa.

Pompo isanayambe, chosungira chapopo chimadzazidwa ndi madzi oti aperekedwe; pambuyo poyambira, chotsitsacho chimayendetsedwa ndi tsinde kuti chizizungulira pa liwiro lalikulu, ndipo madzi omwe ali pakati pa masambawo ayeneranso kuzungulira nawo. Pansi pa mphamvu ya centrifugal, madziwo amaponyedwa kuchokera pakati pa chopondera kupita kumphepete kwakunja ndipo amapeza mphamvu, ndikusiya m'mphepete mwa kunja kwa choyikapo pa liwiro lalikulu ndikulowa mu volute pump casing. Mu volute, madziwo amachepetsedwa chifukwa chakukula kwapang'onopang'ono kwa njira yotuluka, ndipo gawo la mphamvu ya kinetic imasandulika kukhala mphamvu yosasunthika, ndipo pamapeto pake imathamangira mu payipi yotulutsa pamagetsi apamwamba ndikutumizidwa kumalo ofunikira. Pamene madzi akuyenda kuchokera pakati pa choyikapocho kupita kumphepete kwakunja, mpweya wina umapangidwa pakati pa choyikapocho. Popeza kuthamanga pamwamba pa mlingo wamadzimadzi wa thanki yosungiramo ndi yaikulu kuposa kuthamanga kwa polowera papope, madziwo amakanikizidwa mosalekeza mu choyikapocho. Zitha kuwoneka kuti bola ngati choyikapo chimayenda mosalekeza, madziwo amayamwa mosalekeza ndikutulutsidwa.

Mapangidwe oyambira a centrifugal impeller pump amapangidwa ndi magawo asanu ndi atatu, omwe ndi: impeller, pump body,chivundikiro cha mpope, mphete yosungira madzi, shaft ya mpope, kunyamula, mphete yosindikizira, bokosi losungiramo zinthu, ndi chipangizo cha axial force balance.
1. Choyikapo ndiye gawo lalikulu la mpope wapakati. Liwiro lozungulira la chopondera ndilokwera kwambiri, ndipo mphamvu yotulutsa imakhalanso yayikulu kwambiri.
2. Chipompelu chamuchipompelu chamuchipompelu chamuchipompelu chamuchipompelu chamuchipompelu. Imagwira ntchito yothandizira ndi kukonza, ndipo imalumikizidwa ndi bracket yomwe imayikidwapo.
3. Ntchito ya shaft ya pampu ndikugwirizanitsa galimoto ndi chophatikizira ndi kutumiza torque ya galimoto ku chopukutira, kotero ndicho chigawo chachikulu chotumizira mphamvu zamakina.
4. Mphete yosindikiza imatchedwanso mphete yochepetsera kutayikira.
5. Axial mphamvu moyenera chipangizo. Pakugwira ntchito kwa mpope wa centrifugal, popeza madziwo amalowa mu choyikapo pansi pa kupanikizika kochepa ndipo amatuluka pansi pa kuthamanga kwakukulu, kupanikizika kwa mbali zonse za chopondera kumakhala kofanana, ndipo kuponyedwa kwa axial kulowera kumalo olowera kumapangidwa, zomwe zingayambitse rotor kusuntha axially. , zomwe zimayambitsa kufooka ndi kugwedezeka. Ntchito ya axial thrust bearing ndi kulinganiza mphamvu ya axial.

Pali mitundu yambiri yazida zopangira mapampu, wamba ndi zitsulo zosapanga dzimbiri, duplex zitsulo zosapanga dzimbiri, faifi tambala ofotokoza aloyi, mkuwa, ductile chitsulo, imvi chitsulo, etc. Pakati pawo, CF8M zitsulo zosapanga dzimbiri kapena AISI 316L zitsulo zosapanga dzimbiri ndi ntchito kwambiri mu kukana dzimbiri ndi kukana kutentha, amene amawapangitsa kuti azigwiritsidwa ntchito kwambiri mumafuta, mankhwala, mankhwala ndi zina.

RMC Casting Foundry ikhoza kupangapampu ndi ma valvemonga mpope casings, mpope chimakwirira, kubala housings, impellers, etc. zinthu tatchulazi malinga ndi zosowa za makasitomala. Timagwiritsa ntchito kuponya molondola (kutaya sera silika sol kuponyera), kuponyera zipolopolo ndi mchenga kuponya kuti akusowekapo, ndiyeno kutentha mankhwala, CNC Machining, etc. kupanga makonda mpope ndi valavu Chalk. Pa nthawi yomweyo, tikhoza kuchita bwino bwino ndi malo amodzi bwino pa impeller, ndi kalasi akhoza kufika DIN 1940 G2.5. Kwa mapampu ena,matupi a valve, zovundikira pampu ndi zina, titha kuchitanso mayeso osindikiza.
