Uma lezo zinto ezine uzenze ngendlela efanele, upende ungahlala isikhathi esingakanani emotweni?Ngokusobala iminyaka.Phuma phandle ubuke izimoto zidlula uzobona ubufakazi babantu abangazenzi lezo zinto ezine.Empeleni kuyivelakancane ukuthi uma sibona imoto endala ebukeka iyinhle, siyigqolozele.
Ukuzuza impilo enhle yophawu kuhlanganisa nezinyathelo ezine.Kufanele zibonakale, kodwa ake sizibheke noma kunjalo.
Lungiselela iphampu ukuze uvale - lowo umsebenzi womzimba
Thenga uphawu oluhle - upende omuhle
Faka uphawu ngendlela efanele - sebenzisa upende ngendlela efanele
Faka isilawuli esilungile semvelo uma kunesidingo (futhi mhlawumbe kunjalo) - geza futhi ne-wax
Sizobheka ngayinye yalezi zihloko ngokuningiliziwe futhi ngethemba siqale ukwandisa impilo yezimpawu zethu zemishini kuze kube yilapho iningi lazo liguga.Lolu lwazi luhlobene namaphampu amaphakathi kodwa lungasebenza nakunoma yiluphi uhlobo lwemishini ezungezisayo, okuhlanganisa izixube nama-agitator.
Lungiselela ipompo ukuze uvale
Ukuze uzilungiselele kufanele wenze ukuqondanisa phakathi kwepompo nomshayeli, usebenzisa i-laser aligner.I-adaptha yozimele ethi “C” noma “D” iyisinqumo esingcono nakakhulu.
Okulandelayo, ulinganisela ngokuguquguqukayo umhlangano ojikelezayo, ongenziwa kusetshenziswa imishini eminingi yokuhlaziya ukudlidliza, kodwa hlola nomphakeli wakho uma ungenalo uhlelo.Kufanele uqiniseke ukuthi i-shaft ayigobile futhi uyizungezisa phakathi kwezindawo.
Kungumqondo omuhle ukugwema imikhono ye-shaft, njengoba i-shaft eqinile ayinamathuba amaningi okuthi iphambuke futhi ingcono kakhulu kumshini wokuvala uphawu, futhi uzame ukunciphisa ukudonsa kwamapayipi lapho kunokwenzeka khona.
Sebenzisa iphampu yokuklama “yomugqa omaphakathi” uma izinga lokushisa lomkhiqizo lingaphezu kuka-100°C, njengoba lokhu kuzonciphisa izinkinga ezithile zokuqina kwamapayipi epompo.Futhi, sebenzisa amaphampu anobude obuphansi be-shaft kuya ku-diameter ratio.Lokhu kubaluleke kakhulu ngamaphampu esevisi ngezikhathi ezithile.
Sebenzisa ibhokisi lokugxusha eliwusayizi omningi, gwema imiklamo ecijile, futhi unikeze indawo eningi yophawu.Zama ukuthola ubuso bebhokisi lokugxusha njengesikwele ku-shaft ngangokunokwenzeka, okungenziwa ngokusebenzisa amathuluzi abhekene, futhi unciphise ukudlidliza ngokusebenzisa noma imaphi amasu owaziyo.
Kubalulekile ukuthi ungavumeli i-cavitate yepompo, njengoba ubuso be-seal buzovuleka futhi ngokunokwenzeka bonakale.Isando samanzi singenzeka futhi uma amandla elahleka epompo ngenkathi isebenza, ngakho-ke thatha isinyathelo sokuvimbela ukugwema lezi zinkinga.
Kunezinto ezimbalwa okudingeka zihlolwe lapho ulungiselela ipompo yophawu, kufaka phakathi;ukuthi isisindo sephampu/i-motor pedestal okungenani siphindwe kahlanu kune-hardware ehlezi phezu kwayo;ukuthi kukhona amadayamitha ayishumi wepayipi phakathi kokumuncwa kwepompo kanye nendololwane yokuqala;nokuthi i-base plate isezingeni futhi ihlutshiwe endaweni yayo.
Gcina i-impeller evulekile ilungisiwe ukuze unciphise ukudlidliza kanye nezinkinga zokujikeleza kabusha kwangaphakathi, qiniseka ukuthi ama-bearings anenani elifanele lokuthambisa, nokuthi amanzi nezinto eziqinile azingeni emgodini wokuthwala.Kufanele futhi esikhundleni samafutha noma izindebe seal nge labyrinth noma ubuso seal.
Qinisekisa ukuthi ugwema ukulahla imigqa yokuzungeza kabusha exhunywe ebhokisini lokugxusha, ezimweni eziningi ukumuncwa kabusha kuzoba ngcono.Uma iphampu inezindandatho zokugqoka, qiniseka ukuthi uhlola nokuphuma kwazo.
Izinto zokugcina okufanele zenziwe lapho ulungiselela iphampu ukuqinisekisa ukuthi izingxenye ezimanzi zepompo zakhiwe ngezinto ezimelana nokugqwala, njengoba izinto zokuhlanza nezinto ezincibilikisa emigqeni ngezinye izikhathi zidala izinkinga umklami ayengakaze azilindele.
Bese uvala noma yimuphi umoya okungenzeka ukuthi uvuza ohlangothini lokumunca lwepompo bese ususa noma yimuphi okungenzeka uvaleleke kuvolothi.
Thenga uphawu oluhle
Sebenzisa imiklamo elinganiswe nge-hydraulically evala kokubili ukucindezela kanye ne-vacuum futhi uma uzosebenzisa i-elastomer esicini, zama ukusebenzisa i-o-ring.Lezi yizimo ezingcono kakhulu ngezizathu eziningi, kodwa ungavumeli noma ubani ukuthi alayishe i-o-ring noma ngeke igobe noma igoqe njengoba kufanele.
Kufanele futhi usebenzise imiklamo ye-non-fretting seal njengoba i-shaft fretting iyimbangela enkulu yokwehluleka uphawu ngaphambi kwesikhathi.
Izigxivizo ezimile (lapho iziphethu zingazungezi ne-shaft) zingcono kunezinja eziphendukayo (iziphethu ziyazungeza) ukuze kuvale ukukhishwa okuphumayo kanye nanoma iluphi olunye uketshezi.Uma uphawu luneziphethu ezincane, zigcine zingangeni oketshezini noma zizovala kalula.Kunenqwaba yemiklamo yezimpawu enalesi sici esingavali.
Ubuso obunzima obubanzi buhle kakhulu ekunyakazeni kwe-radial esikubona ekusetshenzisweni kwe-mixer kanye nalezo zimpawu ezibekwe kude ukusuka kuma-bearings.
Uzodinga futhi uhlobo oluthile lwe-vibration damping for high temperatures metal bellows seals ngoba ayinayo i-elastomer evame ukwenza lowo msebenzi.
Sebenzisa amadizayini agcina uketshezi oluvala uphawu kububanzi obungaphandle, noma amandla aphakathi nendawo azophonsa okuqinile ebusweni obunamasondo futhi akhawulele ukunyakaza kwawo lapho ikhabhoni iguga.Kufanele futhi usebenzise amakhabhoni angagcwalisiwe ebusweni bezimpawu njengoba ewuhlobo olungcono kakhulu futhi izindleko azikho ngokweqile.
Futhi, qiniseka ukuthi uyakwazi ukuhlonza zonke izinto zokuvala uphawu ngoba akunakwenzeka ukuxazulula inkinga "into eyimfihlakalo".
Ungamvumeli umphakeli ukuthi akutshele ukuthi impahla yakhe ingokobunikazi, futhi uma kuyisimo sabo sengqondo, thola omunye umphakeli noma umenzi, ngaphandle kwalokho ufanelwe yizo zonke izinkinga ozobhekana nazo.
Zama ukugcina ama-elastomer kude nobuso bophawu.I-elastomer ingxenye eyodwa yophawu ezwela kakhulu ekushiseni, futhi izinga lokushisa lishisa kakhulu ebusweni.
Noma yimuphi umkhiqizo oyingozi noma obizayo kufanele futhi uvalwe ngezigxivizo ezimbili.Qiniseka ukuthi ibhalansi ye-hydraulic ikuzo zombili izinkomba noma uyagembula ukuthi obunye bobuso bungase buvuleke ekubuyiseleni emuva kwengcindezi noma ekuqhumeni.
Okokugcina, uma umklamo unekhabhoni ecindezelwe esibambi sensimbi, qiniseka ukuthi ikhabhoni ibicindezelwe hhayi “ishwabene”.Ikhabhoni ecindezelwe izogunda ukuze ihambisane nokungahambi kahle kwesibambi sensimbi, okusiza ukugcina ubuso obunamasondo buphansi.
Faka uphawu ngendlela efanele
I-Cartridge seal iwukuphela kwedizayini enengqondo uma ufuna ukwenza ukulungiswa kwe-impeller, futhi kulula kakhulu ukuyifaka ngoba awudingi ukuphrinta, noma ukuthatha noma yiziphi izilinganiso ukuze uthole umthwalo ofanele wobuso.
I-Cartridge dual seal kufanele ibe nendandatho yokumpompa eyakhelwe ngaphakathi futhi kufanele usebenzise uketshezi lwe-buffer (umfutho ophansi) phakathi kwezivalo noma nini lapho kunokwenzeka ukuze ugweme izinkinga zokuhlanjululwa komkhiqizo.
Gwema noma yiluphi uhlobo lwamafutha njengoketshezi oluyisigcinalwazi ngenxa yokushisa okukhethekile kwamafutha kanye nokungahambi kahle kahle kwamafutha.
Lapho ufaka, gcina uphawu luseduze nama-bearings ngangokunokwenzeka.Ngokuvamile kuba khona indawo yokukhipha uphawu ebhokisini lokugxusha bese usebenzisa indawo yebhokisi lokugxusha ukuze usize ukusimamisa umgodi ojikelezayo.
Ngokuya ngesicelo, kuzodingeka unqume ukuthi ngabe lokhu kusekela bushing kufanele kugcinwe nge-axially.
Izigxivizo ezihlukanisiwe ziphinde zibe nengqondo cishe kunoma yiluphi uhlelo lokusebenza olungadingi uphawu olukabili noma ukufakwa uphawu kokuphuma kombani (ukuvuza kukalwa ngezingxenye ngesigidi ngasinye).
Ukuhlukaniswa kwezimpawu kuwukuphela komklamo okufanele uwusebenzise kumaphampu aneziphetho ezimbili, ngaphandle kwalokho kuzodingeka ukuthi umiselele zombili izimpawu uma uphawu olulodwa kuphela lwehlulekile.
Zikuvumela futhi ukuthi ushintshe izimpawu ngaphandle kokwenza ukuhlangana kabusha nomshayeli wepompo.
Ungagcobi ubuso be-seal lapho ufaka, futhi ugcine okuqinile ebusweni obumboziwe.Uma kunento evikelayo ebusweni bophawu qiniseka ukuthi uyayisusa ngaphambi kokufakwa.
Uma kuwuphawu lwe-rubber bellows seal, zidinga okokugcoba okukhethekile okuzokwenza ukuthi izifutho zinamathele ku-shaft.Ngokuvamile kuwuketshezi olusekelwe ku-petroleum, kodwa ungabuza umphakeli wakho ukuze uqiniseke.I-Rubber bellows seals nayo idinga ukuqedwa kwe-shaft engengcono kune-40RMS, noma irabha izoba nobunzima bokunamathela ku-shaft.
Okokugcina, lapho ufaka kuhlelo lokusebenza olume mpo, qiniseka ukuthi ukhipha ibhokisi lokugxusha ebusweni bophawu.Kungase kudingeke ukuthi ufake lesi sikhala uma umkhiqizi wephampu engazange akunikeze.
Izigxivizo eziningi ze-cartridge zine-vent eyakhelwe ngaphakathi ongakwazi ukuxhuma ekudonseni kwepompo noma enye indawo yokucindezela okuphansi ohlelweni.
Nakekela uphawu
Isinyathelo sokugcina sokuthola impilo enhle ye-seal ukuhlala uyinakekela.Ama-Seal ancamela ukuvala uketshezi olupholile, oluhlanzekile, olugcobayo, futhi nakuba singavamile ukuba nolunye lwalezo esizoluvala, mhlawumbe ungasebenzisa isilawuli semvelo endaweni yebhokisi lokugxusha ukuze uguqule umkhiqizo wakho uwenze owodwa.
Uma usebenzisa ibhokisi lokugxusha elinejakhethi, qiniseka ukuthi ibhantshi lihlanzekile.I-condensate noma umusi uketshezi olungcono kakhulu lokujikeleza ngejazi.
Zama ukufaka i-carbon bushing ekugcineni kwebhokisi lokugxusha ukuze usebenze njengesithiyo esishisayo esizosiza ukuzinzisa izinga lokushisa lebhokisi lokugxusha.
I-Flushing iyisilawuli esiphezulu semvelo njengoba kubangela ukuhlanjululwa komkhiqizo, kodwa uma usebenzisa uphawu olulungile ngeke udinge ukushaywa okuningi.Amalitha amane noma amahlanu ngehora (isaziso ngithe ihora hhayi umzuzu) kufanele anele lolo hlobo lophawu.
Kufanele futhi ugcine uketshezi lunyakaza ebhokisini lokugxusha ukuze uvimbele ukunqwabelana kokushisa.Ukumunca kabusha kuzosusa okuqinile okusindayo kunomkhiqizo owuvalayo.
Njengoba leso kuyisimo esivame kakhulu se-slurry, sebenzisa i-suction recirculation njengendinganiso yakho.Futhi, funda lapho ungayisebenzisi.
Ukukhishwa kabusha kwe-dicharge kuzokuvumela ukuthi ukhuphule ingcindezi ebhokisini lokugxusha ukuze uvimbele uketshezi ekuhwameni phakathi kobuso obumboziwe.Zama ukuthi ungajongi umugqa wokuphinda ujikeleze ebusweni obunamasondo, ungabalimaza.Uma usebenzisa i-metal bellows umugqa wokubuyisela kabusha ungasebenza njenge-sandblaster futhi usike amapuleti ama-bellows amancane.
Uma umkhiqizo ushisa kakhulu, pholisa indawo yebhokisi lokugxusha.Kubalulekile ukukhumbula ukuthi lezi zilawuli zemvelo ngokuvamile zibaluleke kakhulu lapho iphampu imisiwe ngoba izinga lokushisa lokucwilisa kanye nokupholisa ukuvala shaqa kungashintsha izinga lokushisa lebhokisi lokugxusha kakhulu, kubangele ukuthi umkhiqizo ushintshe isimo.
Imikhiqizo eyingozi izodinga i-API.thayipha indlala uma ukhetha ukungasebenzisi izimpawu ezimbili.Izinhlekelele eziyingxenye ye-API.ukucushwa kuzovikela uphawu ekulimaleni ngokomzimba uma kufanele ulahlekelwe i-bearing lapho iphampu isebenza.
Qinisekisa ukuthi uxhumo lwe-API lwenziwa ngendlela efanele.Kulula ukuhlanganisa izimbobo ezine bese uthola ulayini wokuguquguquka noma wokujikeleza kabusha ungene embobeni yokucisha.
Zama ukungafaki isitimu esiningi noma amanzi ngoxhumo lokucisha noma luzongena ebhokisini lokuthwala.Ukuvuza ngaphandle koxhumano lwe-drain kuvame ukubonwa njengokwehluleka kophawu opharetha.Qiniseka ukuthi bayawazi umehluko.
Ukusebenzisa lezi zeluleko zophawu
Ingabe ukhona oke azenze zonke lezi zinto ezine?Ngeshwa akunjalo.Uma singakwenza lokho, amaphesenti angama-85 noma angama-90 ezimpawu zethu azoguga, kunokuba amaphesenti ayishumi noma ayi-15 aguge.Isigxivizo esihlulekile ngaphambi kwesikhathi esinobuso obuningi bekhabhoni obusele sisaqhubeka siwumthetho.
Izaba ezivame kakhulu esizizwayo ukuchaza ukuntula kwethu ukuphila okuhle kwezimpawu ukuthi asikho isikhathi sokukwenza kahle, okulandelwa yinkulumo ethi, “Kodwa sihlala sikhona isikhathi sokukulungisa.”Iningi lethu lenza isinyathelo esisodwa noma ezimbili ezidingekayo futhi lithole ukwanda empilweni yethu yophawu.Akukho lutho olungalungile ngokwanda kwempilo yezimvu zamanzi, kodwa lokho kukude nokugugiswa kwezimpawu.
Cabanga ngakho umzuzu.Uma uphawu luhlala unyaka, inkinga ingaba nkulu kangakanani?Izinga lokushisa alikwazi ukuba phezulu kakhulu noma ingcindezi ibe nzima kakhulu.Ukube lokho bekuyiqiniso bekungeke kuthathe unyaka ukungaphumeleli.Umkhiqizo awukwazi ukungcola kakhulu ngesizathu esifanayo.
Ngokuvamile sithola ukuthi inkinga ilula njengomklamo we-seal onyakazisa umgodi, obangela ukuvuza komkhono olimele noma ku-shaft.Ngezinye izikhathi sithola ukuthi ukushaywa okusetshenziselwa ukuhlanza imigqa kanye ngonyaka kuyicala, futhi akekho oshintsha izinto zokufaka uphawu ukuze zibonise lolu songo ezingxenyeni zophawu.
