MD mtundu migodi kuvala zosagwira multistage centrifugal mpope

Mafotokozedwe Akatundu
MD mtundu migodi kuvala zosagwira Mipikisano siteji centrifugal mpope ndi yopingasa single-suction Mipikisano siteji centrifugal mpope, amene atengera hayidiroliki chitsanzo cha mkulu-mwachangu ndi kupulumutsa mphamvu mankhwala akulimbikitsidwa ndi boma, ndipo ali ndi udindo patsogolo luso mu makampani.Ili ndi ubwino wapamwamba kwambiri, magwiridwe antchito ambiri, otetezeka komanso okhazikika, phokoso lochepa, moyo wautali, kukhazikitsa ndi kukonza bwino, etc. Mtundu uwu wa pampu ya centrifugal yamitundu yambiri yamigodi imagwiritsidwa ntchito kunyamula madzi amchere amchere (tinthu kukula). zosakwana 0.5 mm) ndi olimba tinthu zili zosaposa 1.5% ndi zimbudzi zina zofanana.Zomera zachitsulo, ngalande zamigodi, zoyendetsa zimbudzi ndi zina.

Magwiridwe magawo
Tanthauzo lachitsanzo ndi momwe mungagwiritsire ntchito pampu ya MD yolimbana ndi masitepe ambiri a migodi:
MD155-67×9
MD-ndi pampu yamitundu yambiri yopangira migodi
155—Malo opangira mpope ndi 155m3/h
67 - mutu wa pompano wokhala ndi gawo limodzi ndi 67m
9 - chiwerengero cha magawo a mpope ndi 9

1. Pansi pa madzi oyera (omwe ali ndi tinthu tating'onoting'ono tochepera 0.1%), kugwira ntchito bwino sikudzatsika ndi 6% mutatha kuthamanga kwa 5000h popanda kukonzanso;
2. Pansi pa zimbudzi munali olimba particles pansipa 0,1% kuti 1%, kuthamanga kwa 3000h popanda kukonzanso, ndi dzuwa dontho si upambana 5%;
3. Pansi pa zimbudzi zomwe zili ndi tinthu tating'ono ta 1-.5%, mphamvuyo siidzatsika ndi 6% ngati ikuyenda kwa 2000h popanda kukonzanso kwakukulu.
Mawonekedwe amtundu wa MD pampu ya migodi yosagwira masitepe angapo a migodi:

Gawo la stator limapangidwa makamaka ndi gawo lakutsogolo, gawo lapakati, chowongolera chowongolera, gawo lakumbuyo, chimango chonyamula ndi chivundikiro chachipinda chowongolera.Zigawozo zimagwirizanitsidwa ndi ndodo ndi mtedza.Gawo lakutsogolo ndi gawo lakumbuyo limakhazikika pampando wapampu wokhala ndi mabawuti ndi mtedza.
Zigawo za rotor zimapangidwa makamaka ndi chowongolera, chotchinga, chotchinga chotchinga, diski yolimba ndi mbali za manja za shaft zomangika ndi mtedza waung'ono wozungulira, ndipo zimakhazikika pa shaft ndi makiyi athyathyathya kuti apewe kuzungulira.Rotor yonse imathandizidwa pama bere kumbali zonse ziwiri.Rotor imalumikizidwa mwachindunji ndi mota ndi cholumikizira cha pini chotanuka.
Pofuna kubweza kukulitsa, pad ya mano imayikidwa pakati pa siteji yotsiriza ndi manja oyenerera, omwe ayenera kusinthidwa pamene mpope wasinthidwa.
Pampu yamitundu yambiri ya centrifugal yamigodi yosamva kuvala imatenga kachipangizo kakang'ono ka hydraulic balance chomwe chimatha kulinganiza mphamvu ya axial.Chipangizochi chili ndi magawo anayi: mbale ya balance, mbale ya balance, balance sleeve ndi balance block.
Gawo la rotor la MD mtundu wa mining multistage centrifugal pump umapangidwa makamaka ndi shaft ndi chowongolera, malaya a shaft, disc disc ndi zina zomwe zimayikidwa pa shaft.Chiwerengero cha ma impellers chimadalira chiwerengero cha magawo a mpope.Zigawo zomwe zili pamtunda zimamangiriridwa ndi fungulo lathyathyathya ndi mtedza wa shaft kuti ugwirizane ndi shaft.Rotor yonse imathandizidwa ndi kugudubuza mayendedwe kapena mayendedwe otsetsereka mbali zonse ziwiri.Mapiritsi amatsimikiziridwa molingana ndi mitundu yosiyanasiyana, ndipo palibe imodzi mwa izo yomwe imakhala ndi mphamvu ya axial.Mphamvu ya axial imayendetsedwa bwino ndi disc disc.Panthawi yogwiritsira ntchito mpope, rotor imaloledwa kusambira axially mu mpope casing, ndipo mayendedwe a mpira wa radial sangathe kugwiritsidwa ntchito.Chophimbacho chimayikidwa ndi mafuta, chotsetsereka chimayikidwa ndi mafuta ochepa, ndipo mphete yamafuta imagwiritsidwa ntchito podzipaka yokha, ndipo madzi ozungulira amagwiritsidwa ntchito pozizira.Malo osindikizira pakati pa gawo lolowera madzi, gawo lapakati ndi gawo lotulutsira madzi la mpope zonse zimasindikizidwa ndi mafuta a molybdenum disulfide, ndipo mphete yosindikizira ndi manja owongolera amayikidwa pakati pa gawo la rotor ndi gawo lokhazikika kuti asindikize.Pamene kuchuluka kwa kuvala ndi kung'ambika kwakhudza kugwira ntchito kwa mpope, iyenera kusinthidwa.
Mitundu yosindikiza ya mapampu a migodi a multistage centrifugal amaphatikiza zisindikizo zamakina ndi zosindikizira zonyamula.Pamene mpope imasindikizidwa ndi kulongedza, malo a mphete yonyamula ayenera kukhala yolondola, kulimba kwa kunyamula kuyenera kukhala koyenera, ndipo ndibwino kuti madziwo azitha kutsika ndi dontho.Zinthu zosiyanasiyana zosindikizira za pampu zimayikidwa muzitsulo zosindikizira, ndipo patsekekeyo iyenera kudzazidwa ndi madzi amtundu wina, ndipo kusindikiza madzi, kuziziritsa madzi kapena kuthira madzi ndizosankha.Bushing yosinthika imayikidwa pachisindikizo cha shaft kuteteza shaft ya mpope.
Mayendedwe amtundu uwu wa pampu ya migodi yamitundu yambiri ya centrifugal imayenda mozungulira mukamayang'ana mbali ya mota yoyambirira.
Malangizo oyambira pampu:

Musanayambe migodi Mipikisano siteji centrifugal mpope, mpope rotor ayenera azungulidwe kuona ngati rotor ndi kusintha;
Yang'anani ngati mayendedwe agalimoto akugwirizana ndi momwe mpope akulowera;
Tsegulani valavu yoyamwa pampu, kutseka valavu yachipata cha payipi yotulutsira mpope ndi tambala woyezera kuthamanga, kuti pampuyo idzaze ndi madzi, kapena gwiritsani ntchito vacuum kuti muchotse mpweya mu chitoliro choyamwa ndi mpope;
Yang'anani kulimba kwa ma bolts ogwirizanitsa a mpope ndi galimoto ndi chitetezo kuzungulira mpope, kotero kuti pampu ikukonzekera kuyamba;
Yambani galimoto.Pampuyo ikatha kuyenda bwino, tsegulani tambala woyezera kuthamanga ndikutsegula pang'onopang'ono valavu yachipata cha mpope mpaka cholozera champhamvu chiloze kukakamiza kofunikira (wongoletsani kukweza kwa mpope molingana ndi kuwerengera kwamphamvu kwa potuluka).

Ntchito
Pampu yolimbana ndi masitepe ambiri apakati pa migodi imagwiritsa ntchito njira yoyendetsera pampu kuti igwirizane ndi mphamvu ya axial.Madzi amadzimadzi amachokera ku chipangizo choyezera.Madzi oyenerera amalumikizidwa ndi gawo lolowera m'madzi kuchokera ku chitoliro chamadzi, kapena chitoliro chachifupi chimapangidwa mu chipinda chowongolera.Chubu chimachokera pampopi.Pofuna kuonetsetsa kuti pampu ikugwira ntchito bwino, chitoliro chamadzi sayenera kutsekedwa;
Poyambira ndikuthamanga, muyenera kusamala kuti muwone kuwerengera kwa mita, ngati kutentha kwapang'onopang'ono, kutulutsa kutayikira ndi kutentha, komanso kugwedezeka ndi kumveka kwa mpope ndizabwinobwino.Ngati pali vuto lililonse lachilendo, liyenera kuthetsedwa munthawi yake;
Kusintha kwa kubala kutentha kukwera zimasonyeza msonkhano khalidwe mpope, kubala kutentha kukwera sidzakhala apamwamba kuposa yozungulira kutentha 35 ℃, ndi pazipita kubala kutentha sadzakhala apamwamba kuposa 75 ℃;
Pali kayendedwe kake ka axial ka rotor pampu panthawi yogwira ntchito, ndipo kuyenda kwa axial kuyenera kukhala mkati mwa malo ovomerezeka, ndipo chiwongoladzanja pakati pa mapeto a galimoto ndi kugwirizanitsa kuwiri kwa mpope wamadzi ziyenera kutsimikiziridwa;
Pakugwira ntchito kwa mpope, kuvala kwa chopondera, mphete yosindikizira, manja owongolera, manja a shaft, disc disc ndi mbali zina ziyenera kuyang'aniridwa pafupipafupi.Ngati chovalacho ndi chachikulu kwambiri, chiyenera kusinthidwa panthawi yake.

Imani
Asanatseke, tambala woyezera kuthamanga ayenera kutsekedwa, ndipo valavu yachipata chotuluka iyenera kutsekedwa pang'onopang'ono.Vavu yotuluka ikatsekedwa, mota iyenera kutsekedwa.Pampu itayima mokhazikika, valve yoyamwa ya mpope iyenera kutsekedwa;madzi mu mpope ayenera kumasulidwa.Amatsukidwa ndi kuthiridwa mafuta, amapakidwa kuti asungidwe.
