Xa abantu abaninzi besiva 'impompo yentsimbi engenastainless', baba nomfanekiso weyunithi emenyezelayo, engenakonakala. Leyo yimbono yokuqala ephosakeleyo. Inyaniso kukuba, ibakala libaluleke ngaphezu kweleyibhile. 304 isenokulunga kwisicelo sodluliselo lwamanzi, kodwa uyibeke kwinkqubo yekhemikhali ephakathi okanye, okubi ngakumbi, indawo enetyuwa, kwaye uyakubona ukusilela ngokukhawuleza kunokuba ucinga. Ndibone iiprojekthi ezininzi kakhulu 'ezingenasici' njengento yokubambisa zonke, kuphela ukujongana nomhlwa ongaphambi kwexesha kunye nokutshintshwa kweendleko. Ayisiyomathiriyeli kuphela; imalunga nemathiriyeli efanelekileyo yomsebenzi, kunye nendlela eyenziwe ngayo.
Isiseko sokuCasa: Apho ukuthembeka kuye kwenziwa khona
Kulapho ibali lokwenyani liqala khona. Ukomelela kwempompo akwenziwa nje ubunjineli; ijulwe. Indlu, i-impeller, i-volute-ezi zinto zibalulekileyo ziqala ubomi bazo ngokubumba. Ngaphezulu kwamashumi amathathu eminyaka kule nkalo, ndiye ndafunda ukuba inkqubo yokusekwa ligorha elingavunywanga. Inxalenye ephoswe kakubi, nakwi-316L, iya kuba ne-inclusions, iindawo ezibuthathaka, okanye i-micro-porosity eba ngamanqaku angaphumeleli phantsi koxinzelelo okanye ukuhlaselwa okutshabalalisayo. Awunakukwazi ukwenza umgangatho womatshini ube kukuphosa okubi.
Kungenxa yoko le nto ukufunwa kunye impompo yensimbi engenasici ikhonkco lokwenziwa kwecandelo libalulekile. Ndisebenze nabanikezeli abasika iikona kwinkqubo yokunyibilika okanye unyango lobushushu emva kokuphoswa, kwaye iziphumo zihlala zifana: ukusebenza okungahambelaniyo kunye nobomi obungalindelekanga. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ngokugxila kwabo ixesha elide iqokobhe ngundo ukuphosa kwaye utyalo mali, uyayiqonda le nto. Ixesha labo leminyaka engama-30 alilonani nje; ithetha ngolawulo olusulungekileyo kwi-metallurgy kunye nokwenza i-mold eguqulela ngokuthe ngqo kwingqibelelo yesakhiwo kwicandelo lempompo yokugqibela. Ukubumba iqokobhe, umzekelo, kunika umphezulu ongcono wokugqitywa kunye nokuchaneka komda kunokuphosa isanti yemveli, okuthetha ukuxinana koxinzelelo kunye neempawu ezingcono zokuqukuqela ngaphakathi kwegumbi lokumpompa.
Ndikhumbula iprojekthi apho sasilungisa iimpompo zamanzi okupholisa elunxwemeni. Izindlu zentsimbi yokuqala zazidilika. Satshintshela kwi-a intsimbi engenasici impompo, kodwa ibhetshi yokuqala yokuphosa evela kumboneleli omtsha ayiphumelelanga ngokwe-spectroscopically-umkhondo we-deoxidizers engafanelekanga. Kwafuneka siyilahle yonke into. Yayisisifundo ekuvavanyeni kungekuphela nje isatifikethi semathiriyeli, kodwa iprothokholi yomgangatho wonke we-Foundry. Ukungaguquguquki okuvela kwi-Foundry esele ikhulile akuxoxiswana.
Ukuchaneka koMatshini: Ukulingana okuyalela ukusebenza
Nokuba ukubunjwa okugqibeleleyo kungumfanekiso oqingqiweyo orhabaxa. Ukuchaneka kuvela kumatshini. Ukunyamezela kwi-sleeve ye-shaft yepompo, ukugqitywa komphezulu wegumbi lokutywina, ibhalansi eguquguqukayo ye-impeller-ezi zinto zihlukanisa ihashe elizolileyo, elisebenzayo kwi-vibrating, i-liability evuzayo. CNC Machining ngumgangatho ngesizathu, kodwa ayizizo zonke iivenkile ze-CNC ezilingana neendawo zempompo.
Umngeni nge intsimbi engenasici lutyekelo lwayo lokuqinisa umsebenzi. Ukuba iiparamitha zakho zoomatshini zicimile-isantya sokutya, isantya sokusika, isipholileyo-unokuthi ujongele phantsi iipropathi zemathiriyeli kumphezulu, wenze iifractures ezincinci okanye ulusu oluqinileyo oluthambekele ekuqhekekeni. Ndinee-impellers ezibuyile kubuchwephesha obujongeka bugqibelele kodwa basilela kuvavanyo lokulinganisa kuba indlela yesixhobo yenza uxinzelelo olushiyekileyo. Yinto efihlakeleyo ebonisa kuphela ukusebenza.
Apha kulapho izakhono ezihlanganisiweyo zibalulekile. Iqabane eliphethe zombini ukuphosa kunye ne CNC Machining ngaphakathi, njengeQSY ikhankanya kwimisebenzi yabo, inenzuzo ebalulekileyo. Oomatshini bayaluqonda ulwakhiwo lweenkozo kunye nokuziphatha kwesanti abasebenza nabo. Bangakwazi ukunyenyisa iinkqubo ngokusekelwe kubushushu obuthile intsimbi engenasici okanye i-alloy ekhethekileyo. Oku kuqhubekeka kunciphisa iinguqu kwaye, kumava am, kukhokelela kwicandelo elithembekileyo lokugqibela le impompo yensimbi engenasici umhlanganisi.
IiNuances zeMathiriyeli: Ayinasiphelo nje
Makhe sicacise. I-304, 316, 316L, i-Duplex, i-Super Duplex, kunye ne-nickel-based alloys efana ne-Alloy 20 okanye i-Hastelloy C-zonke ziwela phantsi kwe-ambrela ebanzi 'engenastainless' yeempompo. Ukhetho yinto yonke. I-316L, kunye nomxholo wayo we-molybdenum, yinto engagqibekanga kwimisebenzi emininzi yeekhemikhali, kodwa ubuthathaka bayo yikloridi. Kulapho iintsimbi ze-Duplex, kunye nesakhiwo sazo esixubeneyo se-austenitic-ferritic, singena kunye noxinzelelo olungcono lwe-corrosion cracking resistance.
Ndasebenza kwiprojekthi yesityalo se-biodiesel apho umlambo wenkqubo unamanqatha anamafutha kunye ne-methanol. Siqale sakhankanya i316L. Yahlala isithuba esingangonyaka, emva koko saqala ukubona imingxunya ejikeleze ubuso be-gasket. Kwavela ukuba, umkhondo wekloridi kwi-feedstock ungcoliseko yaba ngunobangela. Kwafuneka siphucule iindawo ezimanzi ukuze zibe a super duplex steel stainless. Kwakuyi-retrofit eneendleko ezinokuthi ziphetshwe ngohlalutyo olunzulu lokuqala lwamanzi kunye nokukhethwa kwezinto eziphathekayo. Isakhelo sempompo kunye nesiseko sinokuhlala njengama-304, kodwa yonke indawo emanzi ifuna ukuphuculwa.
Yiyo loo nto uluhlu lwemathiriyeli yomthengisi luxela. Xa inkampani idwelisa amava nge ialloys ezikhethekileyo njenge-cobalt-based okanye i-nickel-based alloys, ibonisa ukuba baxhotyiselwe imisebenzi enzima-ubushushu obuphezulu, ukutshatyalaliswa kakhulu, okanye ukusetyenziswa kwe-slurry eyingozi. Ezi ayizozisombululo zangaphandle; zifuna ulwazi olukhethekileyo kokubini ukuphosa kunye nomatshini, okondla ngokuthe ngqo ekwakheni olomeleleyo ngokwenene impompo yensimbi engenasici ngenkonzo egqithisileyo.
INdibano kunye neZiporho zokwenyani zeHlabathi
Unokuba nezinto eziphoswe ngokugqibeleleyo kunye noomatshini, kwaye udibanise impompo embi. Ukulingana phakathi kwe-shaft kunye nomkhono, ukulungelelaniswa kobuso be-mechanical seal, ukujikeleza okufanelekileyo kwee-fasteners-ezi kulapho ukusilela kwintsimi kudla ngokuvela khona. Ndibone i-impeller entle yotyalo-mali yonakalisiwe ngenxa yokuba abasebenzi bendibano basebenzise isando ukuyihlalisa kwi-shaft, yothusa iibheringi ukusuka kusuku lokuqala.
Esinye isiporho yi-cavitation. Abantu batyhola impompo, kodwa ihlala ingumba woyilo lwenkqubo. Nangona kunjalo, izinto kunye nokwakhiwa kwempompo kunokuchaphazela umonakalo. Ipompo ye-cavitating iya kudla ngokusebenzisa nayiphi na into, kodwa ibakala eliphantsi intsimbi engenasici okanye oneziphene zokuphosa uya kukhukuliswa aze agrumbe ngokukhawuleza ngokwentlekele. I-high-integrity casting kunye nebakala elifanelekileyo kunokuthengela ixesha lokuxilonga kunye nokulungisa ingxaki yenkqubo ngaphambi kokungaphumeleli ngokupheleleyo.
Zezi ngxaki ze-interstitial-ezo ziphakathi kwe-spec yecandelo kunye nofakelo lokugqibela-ezilawula ubomi bomsebenzi wempompo. Umgangatho wamacandelo esiseko ukusuka kwi-Foundry kunye nevenkile yomatshini ibeka isilingi kwinto enokwenzeka kwintsimi. Ukuba ezo ndawo zilungile, ulwa nemiba yenkqubo, hayi iziphene zezixhobo.
Ukujonga ngasemva ukuqhubela phambili
Ngoko ke, yintoni i-takeway? Ukuchaza a impompo yensimbi engenasici ayingomsebenzi webhokisi yokukhangela. Luthotho lwezigqibo: ialloyi echanekileyo yolwelo kunye nokusingqongileyo, inkqubo yokuphosa ekwaziyo ukuhambisa isandi, isakhiwo esilinganayo, umatshini ochanekileyo ohlonipha iipropati zezinto, kwaye ekugqibeleni, indibano enobuchule kunye nokudibanisa inkqubo.
Xa ndivavanya ababoneleli, ngoku ndijonge ngaphaya kwencwadana yempompo kumnombo wabo wokuvelisa. Imbali efana I-QSY's-Iminyaka engama-30 ekujuleni nasekusebenzeni kwi-spectrum ukusuka kwintsimbi etyhidiweyo ukuya ialloys ezikhethekileyo-ibonisa ubunzulu besinyithi kunye nolwazi lwenkqubo oluhluza ukuthembeka kwemveliso yokugqibela. Abangomthengisi nje; bangumthombo weebhloko zokwakha ezibalulekileyo.
Ngexesha elizayo xa uthatha inxaxheba kwiprojekthi yempompo, yimba kwimvelaphi yecandelo. Buza malunga nendlela yokuphosa, unyango lobushushu, umthombo womatshini. Kulapho idabi lokwenyani lokuphila ixesha elide liphumelele okanye lilahlekile, kwakudala ngaphambi kokuba impompo ibone ithontsi layo lokuqala lolwelo. Umphezulu omenyezelayo sisiphelo sebali elide kakhulu, elineenkcukacha kakhulu.
