Mawonekedwe a pampu - zomwe zimakhudzana pakati pa pampu (ndiye kuti, mphamvu ya pampu) ndi kutuluka kwa maluwa.late kumakubweretserani mwatsatanetsatane

• Mawonekedwe a mawonekedwe a pampu ya centrifugal

Mutu, ukuyenda, mphamvu ndi luso lokhala ndi magawo akulu a pampu ya centrifugal. Ubale pakati pa magawo izi ungatsimikizidwe ndi kuyesa. Dipatimenti yopanga pampu imagwiritsa ntchito magawo oyambira pazogulitsa zake, ndipo ma curve awa amatchedwa mawonekedwe a pampu ya centrifugal. Pofotokoza za kugwiritsa ntchito mapampu ndi ntchito kuti mugwiritse ntchito dipatimenti.

Curve Curve imayesedwa mothamanga, ndipo ndioyenera kuthamanga. Chifukwa chake, mtengo wa liwiro n umasonyezedwa pa mapu okhazikika. Chithunzi 2-6 ndi gawo lapamwamba 4brtifugal pomwe n = 2900r / min feica. Pali ma curve atatu pa chithunzi

1. H -Q Cluve

The H -Q Cluve limawonetsa ubale womwe uli pakati pa kutuluka kwa q ndi mutu wa pampu ndi ojambula h. Mutu wotsatsa pampu wa centrifugal amachepetsedwa ngati kutuluka kwamitundu yayikulu. Mitundu yosiyanasiyana ya mapampu apantrifugal imakhala ndi mawonekedwe osiyanasiyana a H -Q Cluve. Ngati ma curve ena ndi athyathyathya, ndikoyenera nthawi zambiri ndi zosintha zazing'ono m'mutu ndi kusintha kwakukulu; Ma curve ena amakhala okhazikika, ndipo ndizoyenera nthawi zambiri ndikusintha kwakukulu m'mutu wa mutu osalola kusintha kwa magalimoto.

2. N -Q Clump

The N -Q Cluve akuwonetsa ubale womwe uli pakati pa q ndi axis mphamvu n ya pampu, ndipo n imachulukitsa ndi kuchuluka kwa q. Chifukwa chake, poyambira pampu ya centrifugal, kuti muchepetse mphamvu yoyambira, valavu yotulutsa iyenera kutsekedwa.

3.

-Q Curve imayimira ubale womwe uli pakati pa kutuluka q ndi mphamvu ya pampu. Poyamba, zimachulukitsa ndi kuchuluka kwa q, ndipo atatha kufika pamtengo wokwanira, kumachepetsa ndi kuchuluka kwa Q. Mtengo wokwanira wa pun ndi wofanana ndi nthawi yayitali. Pulogalamu imagwira ntchito pamutu wofanana ndi izi, ndipo mphamvu yake ndiyokwezeka kwambiri. Ndiye mfundo iyi ndi yopanga pampu ya centrifugal. Mukamasankha pampu, nthawi zonse ndimakhulupirira kuti pampuyo akugwira ntchito yabwino kwambiri, chifukwa opaleshoniyo ndi azachuma kwambiri pansi pa izi. Komabe, pamapampu nthawi zambiri ndizosatheka kugwira ntchito motere. Chifukwa chake, nthawi zambiri pamafunika kuchuluka kwa ntchito, yotchedwa malo okwera pampu, monga tikuonera mizere ya 2-6 yopotoka. Kuchita bwino kwambiri - madera okwanira sayenera kukhala ochepera 92% ya ntchito yabwino kwambiri. Mapampu onse amadziwika pa dzina, mutu, mutu ndi mphamvu pamalo abwino kwambiri. Katundu wamtundu wa centrifugal ndi malangizo omwe nthawi zambiri amawonetsa kuyenda kwa magalimoto, mutu ndi magetsi osiyanasiyana kwambiri.

• Kukhudzika kwa kuzungulira kwa pampu ya centrifugal pamawu

Mawonekedwe a pampu ya centrifugal amatsimikiziridwa kuti pampu wina. Liwiro litasinthidwa kuchokera ku N1 mpaka N2, kuyandikira kwa kutuluka, mutu, ndi mphamvu zamphamvu ndi

Fomula (2-6) imatchedwa Lamulo la kuchuluka. Kusintha kwa liwiro kuli kochepera 20%, luso likhoza kuonedwa mosasinthika, ndipo cholakwika chowerengera sichili chachikulu.

• Mphamvu yamadzimadzi akuthupi

Mapedidwe omwe amaperekedwa ndi dipatimenti yopanga pampu amapezeka ndi madzi poyesa. Pamene mawonekedwe a madzi onyamula ndi akulu ndipo madzi ndi akulu, mphamvu ya mafayilo komanso kuchuluka kwa ma curves omwe akuyenera kulingaliridwa.

1. Zotsatira za ma viscty:

Makutu akutulutsa madzi amadzimadzi, mphamvu zambiri mu thupi lampikisano. Zotsatira zake, mutu wothamanga ndi kutuluka kwa pampuyo kuyenera kuchepetsedwa, kugwiritsa ntchito bwino kumachepa, ndipo mphamvu ya axis iyenera kuchuluka, motero mawonekedwe amasintha.

2. Mavuto a kachulukidwe:

Kutsatsa mutu wa pampu kulibe chilichonse chokhudzana ndi kuchuluka, komwe kumatha kufotokozedwa mokakamira. Pa liwiro lina, mphamvu ya centrifugal ndiyofanana ndi kachulukidwe ka madzi. Komabe, kukakamizidwa kwa madzi chifukwa cha mphamvu ya ziwonetsero zofanana ndi mphamvu yopangidwa ndi mphamvu ya centrifugal ya kutuluka kwa impeller, kenako kupititsa patsogolo madzi ndi mphamvu yokoka. Mphamvu ya kachulukidwe kamutu imachotsedwa. Komabe, mphamvu ya axis ya pampu imasintha ndi kachulukidwe ka madzi. Chifukwa chake, pamene kuchuluka kwa zosewerera sikuli nthawi yomweyo ngati madzi, y-quve operekedwa ndi pampu satha kugwiritsidwa ntchito, koma kuwerengera kuyenera kuwerengedwa ku (2-4A) ndi (2-5).

Ngati madzi oyendetsedwa ndi yankho lamadzi, kusintha kwa ndende kumakhudzanso mafayilo ndi kachulukidwe ka madzi. Kukula kwakukulu, kusiyana kwakukulu kuchokera kumadzi. Zotsatira zakukhazikika pamapata yokhazikika ya pampu ya centrifugal imawonetsedwanso chifukwa cha kukweza komanso kachulukidwe. Ngati mayendedwe amalima omwe ali ndi zinthu zolimba monga kuyimitsidwa, kupindika kumakhudzidwa ndi mtundu wa zinthu zolimba komanso kugawa kwa granulaty kuwonjezera pa ndende.

Pampu yopingasa ili ndi gulu la akatswiri, lingathandize kasitomala kupeza mtengo woyenera wokhala ndi mtengo wazachuma kwambiri.
