Xa abantu abaninzi besiva 'ipompo kunye ne-valve casting', baba nomfanekiso wentsimbi erhabaxa, emdaka. Yimpazamo yokuqala leyo. Ibali lokwenyani likwijometri ongenakuyibona ngaphandle—iipaseji zangaphakathi, ukuguquguquka kobukhulu bodonga, iindawo zokuhlala. Fumana ezo zingalunganga, kwaye impompo yakho yokusebenza okuphezulu bubunzima bephepha obubizayo. Ayikokwenza imilo; imalunga nokwenza imilo ebambe uxinzelelo, ixhathise umhlwa, kwaye iphile ngokudinwa komjikelo kangangamashumi eminyaka, rhoqo kwindawo ongafuni ukuyindwendwela. Umsantsa phakathi komzobo kunye nokuphosa okusebenzayo kulapho umsebenzi wokwenyani wenzeka khona.
Inyani yoMgangatho weFoundry
Masithethe imathiriyeli kuqala. Iimpawu zokubiza i-CF8M ingenasici kwivalve yenkonzo eyonakalisayo. Ivakala ngokuthe ngqo. Kodwa ukuwelda kweCF8M kunye nokumelana nomhlwa kuxhomekeke ngokupheleleyo kumxholo wayo we-ferrite kunye nendlela olawula ngayo umjikelo wokupholisa kubumba. Ndizibonile iibhetshi apho ikhemistri yayigqibelele ephepheni, kodwa izinga lokupholisa lacinywa yinwele, ekhokelela kwimvula yesigaba se-sigma kwimida yengqolowa. Amalungu aphumelele uvavanyo lokuqala loxinzelelo kodwa aphuhlise i-micro-cracks emva kweenyanga ezintandathu endle. Ukungaphumeleli kwakungekho kukhetho lwezinto eziphathekayo, kodwa kulawulo lwenkqubo ejikeleze loo nto. Leyo yindleko efihliweyo.
Apha kulapho umnombo we-Foundry ubalulekile. Ivenkile efana Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), kunye namashumi amathathu eminyaka kwiqokobhe kunye nokuphosa utyalo-mali, ayithengisi nje isinyithi. Bathengisa imemori yenkqubo. Bayibonile indlela i-tweak encinci kwi-gating system ye-impeller eyinkimbinkimbi yokuphosa kwi-duplex stainless steel inokuthintela ukushwabana kwe-porosity kwingcambu ye-blade-uhlobo lwesiphene olubonisa kuphela phantsi kwe-X-reyi okanye, okubi nakakhulu, ukusilela kwintlekele. Awunakuyifumana loo nto kuqhaqho olutsha. Ibhakiwe-ngaphakathi, ulwazi lokuzama kunye nempazamo.
Ndikhumbula iprojekthi yesingxobo sempompo enamanqanaba amaninzi. Uyilo lwaluneekona ezibukhali ezisuka kwiflange yokufunxa ukuya kwivolute. Lonke ukulinganisa lubonise iindawo ezinokuba shushu. Sabuyela emva naphambili kunye neqela lobunjineli, ekugqibeleni songeza irediya ezifihlakeleyo ezazingekho kwimodeli yokuqala. Kwakuthetha ukuguqula ipateni yewax iyafa, ebiza ixesha kunye nemali. Umthengi wakhalaza malunga nokulibaziseka. Kodwa ukuthululwa kokuqala kwakuvakala, kungekho zinyembezi okanye iintanda. Lo ngumsebenzi ongathandekiyo: ukuphikisana malunga ne-millimeter yokugoba ukuqinisekisa ukunyaniseka kwesakhiwo.
Ukuchaneka Ngaphaya Kwebali
Ukuphosa sisiqingatha kuphela sedabi. Ukuphosa okukrwada akunamsebenzi kwivalve echanekileyo yokutrima okanye umkhono we-shaft yepompo. Umphezulu we-as-cast kunye nokunyamezela kwe-dimensional ngamanqaku okuqalisa. Apha kulapho ubumatshini obudityanisiweyo buba bungenakuxoxisana. Awunako ukuthumela isakhelo kwivenkile yoomatshini begeneric kwaye unethemba lokuba bayasiqonda isakhiwo sedatum okanye iindawo ezibalulekileyo zokutywina. Usomashishini kufuneka azi ukuba yeyiphi imiphezulu efana ne-cast kwaye yeyiphi ekufuneka igqitywe, ukuqonda isibonelelo sesitokhwe kunye nomsebenzi wokugqibela wenxalenye.
QSYukuseta, ukunika zombini ukuphosa kunye nomatshini we-CNC wangaphakathi, ujongana nale ntloko-phezulu. Kumzimba wevalvu, banokuwuphosa besebenzisa inkqubo yokubumba iqokobhe labo ukuze bagqibezele kakuhle umphezulu kunye nokuchaneka komda, emva koko bamatshini ubuso beflange, ibhore, kunye neepokotho zokuhlala kumgangatho omnye, besebenzisa iseti efanayo yemizobo yenkqubo. Oku kuqhubekeka kuphelisa umaleko omkhulu wokunganxibelelani kakuhle. Ndikhe ndajongana namaphupha amabi apho ukuphoswa komatshini okwahlukileyo kwakunemingxuma yebholiti ilungelelaniswe kakuhle kodwa ubuso beflange bebutshintshwe kangangokuba bujikeke phantsi kwetorque yebholiti. Ingxaki yayingengomgangatho womatshini; yayikukunqongophala kwembono epheleleyo yenxalenye.
Ukhetho phakathi kweenkqubo ezifana nokuphosa utyalo-mali kunye nokubumba iqokobhe lamalungu empompo akukhona nje malunga nomthamo. Imalunga nenkcazo yesici. Kwiblayidi ye turbine encinci, entsonkothileyo okanye iplagi yevalvu eneendlela zokupholisa zangaphakathi ezintsonkothileyo, utyalo-mali luyinkosi. Kodwa kwicasing yempompo enecandelo elikhulu elinzima okanye ibhonethi yevalve, ukungunda kweqokobhe elomeleleyo kunokonga ngakumbi kwaye kuchanekile kwiimpawu ezifunekayo. Sisigqibo sobunjineli bexabiso esifuna uthethwano olunyanisekileyo, hayi nje ukuthengisa eyona ndlela ibiza kakhulu.
Xa ii-alloys zisenza umahluko
Ukuhamba ngaphaya kweentsimbi eziqhelekileyo ezingenasici kwi-nickel-based okanye i-cobalt-based alloys itshintsha yonke into. Ezi zidla ngokuba ziinkonzo ezigqithisileyo: iivalvu ezinobushushu obuphezulu kwiindawo zokucokisa, okanye iinxalenye zempompo ezibamba udaka olunoburharha obugqithisileyo emigodini. Iimpawu zokuphosa zahluke ngokupheleleyo. Zihlala zibonakala kakhulu xa zinyibilikile, zineendawo eziphezulu zokunyibilika, kwaye ziqhelene neziphene ezithile njengokukrazuka okushushu ukuba uyilo lokungunda aluhambisani.
Ukusebenza ngezi ngxubevange zikhethekileyo ayisiyonto udlala kuyo. Ifuna i-linings ezinikeleyo eziko, umoya olawulwayo, kunye nabasebenzi abayaziyo ifestile yobushushu obuchanekileyo bento efana ne-Hastelloy C-276. Ivenkile edwelisa ezi zixhobo, njenge QSY yenza, kukubonisa amandla, kodwa imema umxhasi ogocagoca ngakumbi. Imida yempazamo minuscule. Ndithathe inxaxheba kwiprojekthi yealloy 20 valve bodies ukwenzela inkonzo ye-sulfuric acid. Ulawulo lwekhemistri, ngakumbi kumanqanaba ekhabhoni kunye ne-silicon, yayikhohlakele. Ubushushu obunye bemka kancinane, yaye yonke ibhetshi kwafuneka ichithwe—isifundo esinamanani amathandathu sokuhlala silindile.
Unyango lobushushu lwasemva kokuphoswa kwezi ngxubevange lelinye inyathelo elibalulekileyo elidla ngokuba yinto yokucinga. Isisombululo se-annealing kunye nokucinywa kwee-duplex steels, okanye ukunciphisa uxinzelelo kwii-heavy-section castings, kufuneka zenziwe ngendlela echanekileyo. Isithando somlilo esingalinganisi ngokufanelekileyo sinokuhlehlisa wonke umsebenzi wenkathalo wesiseko. Sesinye isizathu sokuba udibaniso oluthe nkqo, ukusuka kwinyibilika ukuya kumatshini, lubonelela ngomkhondo wophicotho oluthembekileyo lomgangatho.
Indawo yeFriction: Uyilo lokuVeliswa
Owona mthombo mkhulu wokulibaziseka kunye nokugqithiswa kweendleko akusiyo isiseko; ngumzobo. Iinjineli ziyila umsebenzi, zichanekile, kodwa ngamanye amaxesha ziyila iijiyometri eziphantse zingenzeki ukuphosa ngokuvakalayo. Umzekelo weklasikhi yi-flange engqindilili edityaniswe ngokuthe ngqo kwindonga encinci ngaphandle kokutshintshwa ngokuthe ngcembe. Ngumgodi wokushwabana oqinisekisiweyo. Okanye ukugqibezela ngokungekho ngqiqweni okugudileyo njengokuphoswa komphezulu kwipaseji yonke yangaphakathi.
Uthethathethwano kwangethuba lungundoqo. Iqabane elihle elisisiseko liya kwenza uphononongo loyilo, hayi nje ukucaphula iindleko. Baza kucebisa ii-engile zokuyila, bacebise ukuhambisa umgca wokwahlula, okanye bacebise ukuguqula into enzima-ukuphosa into efakwe ngoomatshini eyahlukileyo. Le ntsebenziswano isindisa intlungu enkulu kamva. Ndikhumbula uyilo lwesigqubuthelo sempompo esinendawo enzulu, emxinwa. Ipatheni yokuqala ivelise ukubandakanywa kwesanti okungaguqukiyo. Isicombululo yayingekokubeka ityala kwisanti ebumbayo; yayikukutshintsha kancinane i-engile ye-recess kunye nokongeza i-chill encinci kwi-mold ngelo xesha ukuqinisa isinyithi ngokukhawuleza. Ulungiso olulula, kodwa lufuna igalelo lesiseko.
Eli lixabiso elisebenzayo leqabane elinamava anzulu. Iwebhusayithi yabo, https://www.tsingtaocnc.com, ibonisa ububanzi bawo, kodwa uvavanyo lwangempela lukwi-imeyile yangasemva kunye ne-imeyile kunye nemizobo ephawulweyo ngexesha leprojekthi yeprojekthi. Kulapho ubona khona ukuba bangabathathi-odolo nje okanye ngabadibanisi bokwenene bobugcisa.
Ukujonga Iphelele, Kungekhona Nje Inxalenye
Okokugqibela, kubalulekile ukucinga malunga nokuphosa njengenxalenye yenkqubo. Ivalve ayingomzimba kunye nebhonethi nje. Imalunga nendlela i-wedge yevalve yesango lokuphonswa ngayo ikhonkco kunye neringi yesitulo esiphosiweyo, zombini zinokwenzeka ukusuka kwindawo enye kodwa zifuna iipropathi zemathiriyeli ezihambelanayo ukunqanda inyonyo. Ukuhambelana kumacandelo amaninzi okuphoswa yinzuzo enkulu.
Ngokufanayo, kwiimpompo, ukusebenza kwe-hydraulic kuxhomekeke kumphezulu wangaphakathi ogqityiweyo kunye nokunyaniseka kwedimensional ye-cast volute kunye ne-impeller. Ukutenxa kancinci kwiprofayili ye-impeller vane ukusuka kuyilo ngenxa yokugqwethwa kokuphosa okanye ukungonelanga komatshini kunokubulala ukusebenza kwempompo. Awuthengi nje ingqokelela yamalungu esinyithi; uthenga umxhasi kwindlela yokusebenza kunye nexesha lokuphila.
Oku kusizisela isangqa esipheleleyo. Impompo kunye ne-valve castings zisisiseko. Umgangatho wabo umisela ukuthembeka kwenkqubo yonke yamanzi. Licandelo apho ulwazi lwethiyori kufuneka lungcungcuthekiswe ngamava asebenzayo, ngamanye amaxesha aphumelele nzima. Injongo asikokunikela nje inxalenye ehambelana noshicilelo. Kukuhambisa inxalenye oyaziyo, esekelwe kuloo mava, iya kusebenza xa uxinzelelo luphezulu, ubushushu bugqithise, kwaye ukuvala ukulungiswa akukhethi. Nguwo lowo umlinganiselo.
