Luluvo olulungileyo ukunqanda imikhono ye-shaft, njengoko ishafti eyomeleleyo ayinakufane ijike kwaye ingcono kakhulu kwitywina lomatshini, kwaye uzame ukunciphisa uxinzelelo lwemibhobho naphi na apho kunokwenzeka.
Sebenzisa impompo yokuyila "yomgca osembindini" ukuba ubushushu bemveliso bungaphezulu kwe-100 ° C, njengoko oku kuya kunciphisa ezinye iingxaki zemibhobho kwimpompo. Kwakhona, sebenzisa iimpompo ezinobude obuphantsi be-shaft ukuya kwi-diameter ratio. Oku kubaluleke kakhulu kwiimpompo zeenkonzo zethutyana.
Sebenzisa ibhokisi yokufaka enkulu, unqande uyilo olucekethekileyo, kwaye unike indawo eninzi yokutywina. Zama ukufumana ubuso bebhokisi yokugxumeka njengesikwere kwi-shaft ngokusemandleni, enokuthi yenziwe ngokusebenzisa izixhobo ezijongene nazo, kwaye unciphise ukungcangcazela ngokusebenzisa naziphi na iindlela ozaziyo.
Kubalulekile ukuba ungayivumeli impompo i-cavitate, njengoko ubuso betywina buya kugqabhuka buvuleke kwaye bunokonakala. Ihamile yamanzi inokuthi yenzeke ukuba amandla alahlekile kwimpompo ngelixa eqhuba, ngoko thatha inyathelo lokuthintela ukuphepha ezi ngxaki.
Kukho izinto ezimbalwa ezifunekayo ukuba zihlolwe xa ulungiselela ipompo yokutywina, kuquka; ukuba ubunzima bempompo / i-motor pedestal ubuncinci buphindwe kahlanu ubunzima be-hardware ehleli kuyo; ukuba kukho iidayamitha ezilishumi zombhobho phakathi kokufunxa impompo kunye nengqiniba yokuqala; kunye nokuba i-base plate ikwinqanaba kwaye ihlulwe endaweni.
Gcina i-impeller evulekileyo ihlengahlengiswe ukunciphisa ukungcangcazela kunye neengxaki zangaphakathi zokujikeleza kwakhona, qinisekisa ukuba iibheringi zinexabiso elifanelekileyo lokuthambisa, kwaye amanzi kunye nezinto eziqinileyo azingeni kwi-bearing cavity. Kufuneka kwakhona ubeke indawo yegrisi okanye i-lip seal nge-labyrinth okanye i-face seal.
Qinisekisa ukunqanda ukukhupha iilayini zokujikeleza kwakhona eziqhagamshelwe kwibhokisi yokuhlohla, kwiimeko ezininzi ukufunxa kwakhona kuya kuba ngcono. Ukuba impompo ineringi zokunxiba, qiniseka ukuba ujonga ukucoceka kwazo.
Izinto zokugqibela omawuzenze xa ulungiselela impompo kukuqinisekisa ukuba iindawo ezimanzi zempompo zenziwa ngezinto ezikwaziyo ukumelana nomhlwa, njengoko izicoci kunye nezinyibilikisi emigceni maxa wambi zibangela iingxaki umyili angazange azilindele.
Emva koko vala nawuphi na umoya ovuza kwicala lokufunxa lempompo kwaye ususe nayiphi na into enokubanjiswa kwivoluti.
Thenga isitywina esilungileyo
Sebenzisa uyilo olulungelelanisiweyo lwe-hydraulically oluvala zombini uxinzelelo kunye ne-vacuum kwaye ukuba uya kusebenzisa i-elastomer kwisitywina, zama ukusebenzisa i-o-ring. Ezi zezona milo zingcono ngenxa yezizathu ezininzi, kodwa ungavumeli nabani na entwasahlobo alayishe i-o-ring okanye ayiyi kugoba okanye iqengqeleke njengoko kufanelekile.
Kuya kufuneka usebenzise uyilo lwetywina olungagungqiyo njengoko i-shaft fretting ingoyena nobangela wokusilela kwetywina kwangaphambi kwexesha.
Amatywina amileyo (apho imithombo ingajikelezi neshafti) angcono kunezitywina ezijikelezayo (imithombo iyajikeleza) yokuvala izinto ezikhutshwayo eziphumayo kunye naluphi na olunye ulwelo. Ukuba itywina linemithombo emincinci, zigcine ngaphandle kolwelo okanye ziya kuvaleka ngokulula. Kukho intaphane yoyilo lwetywina olunolu phawu lungavaliyo.
Ubuso obunzima obubanzi bugqwesile kwintshukumo yeradial esiyibonayo kwizicelo zomxube kunye nezo zitywina ezibekwe ngokwasemzimbeni umgama omde ukusuka kwiibheringi.
Uya kufuna kwakhona uhlobo oluthile lokudambisa i-vibration yobushushu obuphezulu bentsimbi yentsimbi yokutywina ngenxa yokuba ayinayo i-elastomer eqhele ukwenza loo msebenzi.
Sebenzisa iziyilo ezigcina ulwelo lokutywina kwidayamitha engaphandle kwetywina, okanye amandla e-centrifugal aya kuphosa izinto eziqinileyo kubuso obubambekayo kwaye ithintele intshukumo yazo xa ikharbhon inxiba. Kuya kufuneka usebenzise iikhabhoni ezingazaliswanga kubuso betywina njengoko zezona zilungileyo kwaye ixabiso aligqithisi.
Kwakhona, qiniseka ukuba unokuchonga zonke izixhobo zokutywina kuba akunakwenzeka ukulungisa ingxaki "izinto ezifihlakeleyo".
Musa ukuvumela umthengisi akuxelele ukuba impahla yakhe yeyakho, kwaye ukuba eso sisimo sabo sengqondo, fumana omnye umthengisi okanye umenzi, kungenjalo ufanelwe zizo zonke iingxaki oya kuba nazo.
Zama ukugcina ii-elastomers kude nobuso betywina. I<em>elastomer lelona candelo letywina lelona libuthathaka kakhulu kubushushu, kwaye ubushushu bushushu kakhulu ebusweni.
Nayiphi na imveliso eyingozi okanye ebiza imali eninzi kufuneka itywinwe ngamatywina amabini. Qinisekisa ukuba ibhalansi ye-hydraulic ikumacala omabini okanye ungcakaza ukuba ubuso obunye bunokuvuleka kuxinzelelo lokubuyisela umva okanye utyando.
Ekugqibeleni, ukuba idizayini inekhabhoni ecinezelwe kwisibambi sesinyithi, qiniseka ukuba ikhabhoni yayicinezelekile kwaye "ingabikho". Ikhabhoni ecinezelweyo iya kucheba ukuze ihambelane nezitenxo kwisibambi sentsimbi, inceda ukugcina ubuso obubambekayo buthe tyaba.
Faka itywina ngokuchanekileyo
Amatywina eCartridge luyilo kuphela olunengqiqo ukuba ufuna ukwenza uhlengahlengiso lwe-impeller, kwaye kulula kakhulu ukuyifaka kuba awudingi ushicilelo, okanye ukuthatha nayiphi na imilinganiselo ukufumana umthwalo ochanekileyo wobuso.
Iikhatriji ezitywina kabini kufuneka zibe neringi yokumpompa eyakhelwe ngaphakathi kwaye kufuneka usebenzise ulwelo lwe-buffer (uxinzelelo olusezantsi) phakathi kwezitywina nanini na kunokwenzeka ukunqanda iingxaki zokuhlanjululwa kwemveliso.
Kuphephe naluphi na uhlobo lwe-oyile njengolwelo olukhuselayo ngenxa yobushushu obukhethekileyo be-oyile kunye nokuqhuba kakubi.
Xa ufaka, gcina isitywina ngokusondeleyo kwiibheringi ngokusemandleni. Ngokuqhelekileyo kukho indawo yokuhambisa itywina ngaphandle kwebhokisi yokupakisha kwaye usebenzise indawo yebhokisi yokufaka i-bushing yokuxhasa ukunceda ukuzinzisa i-shaft ejikelezayo.
Ngokuxhomekeke kwisicelo, kuya kufuneka wenze isigqibo sokuba le nkxaso bushing kufuneka igcinwe axially.
Ukwahlula amatywina akwenza ingqiqo malunga naso nasiphi na isicelo esingafuni ukutywinwa kabini okanye ukutywinwa okuphuma kwembacu (ukuvuza kulinganiswe ngamalungu kwisigidi ngasinye).
Ukwahlula amatywina luyilo kuphela omele ulusebenzise kwiimpompo eziphela kabini, kungenjalo kuya kufuneka utshintshe omabini amatywina xa itywina elinye kuphela lisilele.
Bakwakuvumela ukuba utshintshe amatywina ngaphandle kokwenza ulungelelwaniso nomqhubi wempompo.
Musa ukuthambisa ubuso betywina xa kufakelwa, kwaye ugcine izinto eziqinileyo ebusweni obunxityiweyo. Ukuba kukho isambatho esikhuselayo ebusweni betywina qiniseka ukuba uyayisusa ngaphambi kokufakwa.
Ukuba sisitywina se-rubber bellows, zifuna i-lubricant ekhethekileyo eya kubangela ukuba imibhobho ibambelele kwi-shaft. Kuqhelekile ukuba lulwelo olusekwe kwipetroleum, kodwa ungajonga kumthengisi wakho ukuze uqiniseke. Izitywina ze-Rubber bellows zifuna ukugqitywa kwe-shaft engekho ngcono kune-40RMS, okanye irabha iya kuba nobunzima bokunamathela kwi-shaft.
Okokugqibela, xa ufaka kwisicelo esithe nkqo, qiniseka ukuba ukhupha ibhokisi yokupakisha ebusweni betywina. Kusenokufuneka uyifakele le venti ukuba ngaba umenzi wempompo akazange ayibonelele.
Amatywina amaninzi e-cartridge ane-vent eyakhelwe ngaphakathi ukuze udibanise kwipompo yokufunxa okanye enye indawo yoxinzelelo oluphantsi kwinkqubo.
Qaphela itywina
Inyathelo lokugqibela ekufezekiseni ubomi botywino obulungileyo kukuhlala unyamekela. Amatywina akhetha ukutywina ulwelo olupholileyo, olucocekileyo, oluthambisayo, kwaye ngelixa singafane sibe nenye yezo zokutywina, mhlawumbi ungasebenzisa ulawulo lokusingqongileyo kwindawo yebhokisi yokuhlohla ukutshintsha imveliso yakho ibenye.
Ukuba usebenzisa ibhokisi yokufaka ibhatyi, qiniseka ukuba ibhatyi icocekile. I-Condensate okanye umphunga zezona ziselo zilungileyo zokujikeleza ngebhatyi.
Zama ukufaka i-carbon bushing ekupheleni kwebhokisi ye-stuffing ukuze usebenze njengomqobo we-thermal oya kunceda ukuzinzisa ubushushu bebhokisi.
Ukugungxula lolona lawulo lokusingqongileyo njengoko lubangela ukunyibilika kwemveliso, kodwa ukuba usebenzisa itywina elichanekileyo awuyi kufuna ukugungxulwa okuninzi. Iilitha ezine okanye ezintlanu ngeyure (isaziso ndithe iyure hayi umzuzu) kufuneka zanele olo hlobo lwesitywina.
Kufuneka kwakhona ugcine ulwelo oluhambayo kwibhokisi yokuhlohla ukuthintela ukugcwala kobushushu. Ukufunxa kwakhona kuya kususa izinto eziqinileyo ezinobunzima kunemveliso oyitywinayo.
Kuba leyo yeyona meko ixhaphakileyo eludaka, sebenzisa i-suction recirculation njengomgangatho wakho. Kwakhona, funda apho ungayisebenzisa khona.
Ukukhutshwa kwakhona kwe-dicharge kuya kukuvumela ukuba unyuse uxinzelelo kwibhokisi yokufaka ukuthintela ulwelo ukuba lube ngumphunga phakathi kobuso obugqunyiweyo. Zama ukuba ungajolisi umgca wokujikeleza kwakhona kubuso obunxibileyo, unokubenzakalisa. Ukuba usebenzisa intsimbi yentsimbi umgca wokujikeleza unokusebenza njengentlabathi kwaye unqumle iipleyiti ezibhityileyo.
Ukuba imveliso ishushu kakhulu, pholisa indawo yebhokisi yokufaka. Kubalulekile ukukhumbula ukuba olu lawulo lokusingqongileyo luhlala lubaluleke kakhulu xa umpompo umisiwe ngenxa yokuba amaqondo obushushu e-soak kunye nokupholisa okuvaliweyo kunokutshintsha ubushushu bebhokisi yokufaka kakhulu, kubangele ukuba imveliso itshintshe isimo.
Iimveliso ezinobungozi ziya kufuna i-API. uhlobo lwedlala ukuba ukhetha ukungasebenzisi amatywina amabini. I-bushing yentlekele eyinxalenye ye-API. uqwalaselo luya kukhusela itywina kumonakalo womzimba ukuba ufanele ulahlekelwe ngumthwalo xa impompo isebenza.
Qinisekisa ukuba udibaniso lwe-API lwenziwe ngokuchanekileyo. Kulula ukuxuba amazibuko amane kwaye ufumane umgca wokugungxula okanye wokuphinda ujikeleze kwizibuko lokucima.
Zama ukuba ungafaki umphunga omninzi okanye amanzi ngoqhagamshelo lokucima okanye luya kungena kwindawo yokuthwala. Ukuvuza ngaphandle komdibaniso wombhobho kudla ngokubonwa njengokusilela kwetywina ngabaqhubi. Qiniseka ukuba bayawazi umahluko.
Ukuphumeza ezi ngcebiso zokutywinwa
Ngaba ukho umntu owakhe wazenza zonke ezi zinto zine? Ngelishwa akunjalo. Ukuba sikwenzile oko, ama-85 okanye ama-90 epesenti yamatywina ethu aya kuphelelwa, kunokuba ishumi okanye i-15 lepesenti liguge. Isitywina esisilele kwangaphambi kwexesha esinobuso obuninzi bekhabhoni eshiyekileyo sisaqhubeka singumthetho.
Esona sizathu sixhaphakileyo esisivayo sichaza ukunqongophala kwethu kobomi betywina kukuba alikho ixesha lokuyenza ngokufanelekileyo, lilandelwa ngumbhalo othi, "Kodwa lihlala likho ixesha lokuyilungisa." Uninzi lwethu lwenze inyathelo elinye okanye amabini ayimfuneko kwaye namava ukwanda kubomi bethu botywino. Akukho nto iphosakeleyo ngokunyuka kobomi betywina, kodwa leyo yindlela ende yokunxiba amatywina.
Yicinge loo nto okomzuzwana. Ukuba itywina lithatha unyaka, ingaba inkulu kangakanani ingxaki? Iqondo lobushushu alinakuba phezulu kakhulu okanye uxinzelelo lubenzima kakhulu. Ukuba oko bekuyinyani bekungazukuthatha unyaka ukusilela ukutywinwa. Imveliso ayikwazi ukuba mdaka kakhulu ngenxa yesizathu esifanayo.
Sihlala sifumanisa ukuba ingxaki ilula njengoyilo lwetywina olukhathaza i-shaft, ebangela indlela evuzayo ngomkhono owonakeleyo okanye ishaft. Ngamanye amaxesha sifumanisa ukuba i-flush esetyenziselwa ukucoca imigca kanye ngonyaka ngumtyholwa, kwaye akukho mntu uguqula izinto zokutywina ukubonisa esi songelo kumacandelo okutywinwa.
