Iyo wunvise 'impeller', benshi batekereza ko ari umufana gusa muri pompe cyangwa kuvanga. Ngiyo imyumvire ya mbere itari yo. Mubyukuri, geometrie yacyo - inguni yicyuma, gupfunyika, ubugari bwo gusohoka - itegeka ibintu byose uhereye kumikorere ya sisitemu kugeza igihe cyinteko yose. Nabonye imishinga myinshi aho uwatumaga yari yatekerejweho, biganisha ku rusaku rwa cavitation rwumvikana nka kaburimbo mu muyoboro cyangwa pompe igenda hejuru yikirenga mu mezi. Numutima, ntabwo ari ibikoresho.
Ibya Sekibi muburyo bwo gukina
Kubona imiterere neza itangirana nububiko. Kubimoteri bigoye, cyane cyane bifunze cyangwa igice gifunguye hamwe nibisobanuro bifatika, gushora imari ninzira yonyine ishobora kubaho. Igishashara cyerekana ibishashara ni byose. Inenge ntoya mu rupfu, idahuye gato, igenda yigana muri buri casting. Ndibuka icyiciro cya pompe ya marine bilge aho impande zikurikira za blade zahoraga zibyibushye kuruta spec. Ntabwo byananiye kugenzura ibipimo, ariko imikorere yo kugabanuka yarangiye hafi 15%. Nyirabayazana? Kugabanuka kw'ibishashara ntabwo byishyuwe byuzuye muburyo bwo gupfa. Iri ni isomo rihenze wize atari ku kibaho cyo gushushanya, ariko nyuma yo gusuka ibice amagana.
Aha niho uburambe bwumushinga bwerekana. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), hamwe nimyaka yabo muri shell no gushora imari, yabona ibi. Birashoboka ko babonye ibintu byose bigabanuka no kugoreka igitabo. Gukorana n'ibyuma bidafite ingese cyangwa nikel-ishingiye kuri nikel kubikorwa byangirika byongera urundi rwego; gutembera kwicyuma no gukonjesha biratandukanye. Ntushobora gukoresha inzira ya karubone gusa. Ibikorwa byabo byigihe kirekire byerekana ko bahinduye tekinike zabo mubikoresho, nibyingenzi.
Rimwe na rimwe, ikibazo ntabwo ari ugukina ahubwo ni ugusukura. Ubuso busa mu gice cyururimi rwinshi cyangwa kuruhande rwumuvuduko ukenera gusya neza. Kurenza-gusya agace kamwe, hanyuma ugahindura umwirondoro wa hydraulic. Nakomeje gutsimbarara ku gukoresha icyerekezo cyo gusya cyerekanwe kubatwara ibintu bikomeye, amaduka amwe akabona arambiwe. Ariko nibyo cyangwa ibyago byo guhindagurika nyuma.
Imashini: Aho Igitekerezo gihurira na Chuck
Ndetse na casting nziza ikenera gutunganywa neza. Bore kuri shaft, hub ireba, kandi cyane cyane, kuringaniza imbaraga. Aha niho CNC igaragaza agaciro kayo. Ukeneye imashini ishobora gukemura ikibazo cyo guhagarika icyuma nta kuganira. Nakoze kumushinga wikubye kabiri aho iduka ryambere ryagerageje gukora imashini hejuru yicyuma hamwe nuburyo busanzwe bwa 3-axis. Kurangiza byari biteye ubwoba, kandi kuringaniza byari inzozi-bisaba gucukura bikabije.
Igikoresho gikwiye cyinshi ni cyiza. Iragufasha kwiyegereza icyuma cyane. Ibisobanuro bya tekiniki kuri https://www.tsingtaocnc.com garagaza ubushobozi bwabo bwa CNC, nibyo rwose bikenewe. Kubyihuta byihuta bya pompe, urwego ruringaniza (nka G2.5 cyangwa G1.0). Kubigeraho ntabwo ari ugukuramo ibiro gusa; bijyanye nuburinganire bwambere buva kumashini. Niba CNC ikora kuri hub na blade ihuza, gukosora kuringaniza ni bike kandi ntibibangamira ubusugire bwimiterere.
Twigeze gushakisha compressor zimwe na zimwe muri cobalt. Imashini yari inyamaswa. Ibikorwa bikora-bikomera vuba. Amaduka yagombaga guhindura ibiryo, umuvuduko, no gukoresha ibikoresho byihariye bitwikiriye akazi. Ntabwo cyari igitabo cyibitabo; byahoraga bihinduranya bishingiye kubikoresho byo kwitegereza. Iduka rifite imashini gusa ibyuma byoroheje byari gusenya ibice.
Guhitamo Ibikoresho ntabwo ari Ruswa gusa
Umuntu wese atora 316 idafite umwanda kumazi yinyanja. Ni intangiriro nziza. Ariko kubyihuta byihuta, nko mumashanyarazi menshi yo kuzamura pompe, imbaraga zumubiri hamwe no kurwanya umunaniro biba ibyambere. Icyuma gitera icyuma gishobora kuba cyiza kuri 1800 rpm, ariko kuri 3600 rpm, impungenge za centrifugal zikubye kane. Nibwo urebye duplex idafite umwanda cyangwa na nikel alloys nka Inconel 725.
Ndibuka umushinga wa retrofit aho twasimbuye ibyuma bitera ibyuma hamwe nicyuma cyo murwego rwohejuru rwicyuma muri pompe yihuta, twibwira ko gikomeye. Byari, ariko nanone byari byoroshye. Ingaruka ziva mubice bikomeye byateje micro-crack kumuzi wicyuma, biganisha ku kunanirwa gukabije. Twasubiye inyuma kandi dukoresha martensitike ikomye - idafite ubukana, ntabwo ikomeye. QSY'kuvuga gukorana na alloys nka cobalt na nikel-ishingiye ni urufunguzo hano. Bisobanura ko basobanukiwe nubushakashatsi bwihariye bwibikoresho, ntabwo ari chimie gusa.
Rimwe na rimwe, guhitamo nabi ni ukuzigama amafaranga ku bikoresho ubwabyo, ariko birengagiza igiciro cyose. Ibyuma bya karubone bihendutse mubidukikije byoroheje bishobora kumara umwaka. Umwanya wo guhagarika no gusimbuza umurimo watwaye inshuro icumi itandukaniro ryibintu. Nibikorwa byoroshye kubara abakora akenshi babura.
Kwishyira hamwe hamwe na sisitemu Ingaruka
Umuntu wimuka ntabwo akora wenyine. Imikorere yacyo ihujwe na volute casing clearance, ibiyobora imiyoboro ya suction, ndetse na valve yo hepfo. Ikosa rya kera ni ugushiraho uburyo bukomeye bwo kwimura ibintu bishaje, byambarwa hamwe no kwiyongera imbere. Inyungu zikorwa ntizihagije kuko igihombo cyo kuzenguruka kirya inyungu zose.
Twagerageje rimwe. Gishya, cyiza impeller mu gashya gashya hitamo 82%. Imashini imwe mu isanduku ifite 0.5mm yagutse yo kwambara impeta (iracyari mu mbibi zemewe zo kuvugurura) yagabanutse kugera kuri 78%. Ngiyo amakuru yukuri-yisi utazabona kurupapuro rwihariye. Bikwiye, cyane cyane nimpeta zisimburwa, ni umuhango wo kubungabunga utitaweho.
Ikindi kibazo cya sisitemu ni Net Positive Suction Head (NPSH). Imashini nziza kandi yimashini izakomeza gutobora niba sisitemu NPSHA iri hasi cyane. Nahamagariwe gusuzuma ikibazo cyo kunanirwa kwimuka aho ibyuma byangiritse, gusa nasanze ikibazo cyari akayunguruzo kafunze cyangwa umurongo utomora munsi ya metero eshatu hejuru. Uwimuka yari uwahohotewe, ntabwo yabiteye.
Kunanirwa nkigikoresho cyo gusuzuma
Wiga byinshi kubitsinzwe byananiranye kuruta ibyuzuye. Uburyo bwo kuvunika buvuga inkuru. Umunaniro ucika ukomoka kumuzi? Birashoboka guhindagurika cyangwa inenge yibintu. Isuri imwe kumurongo wambere? Cavitation. Ahantu hakeye kuri blade yihariye? Birashobora kuba kugoreka kuva inkokora iri hafi. Mbitse ububiko bwamafoto yananiwe. Nibikoresho byiza byamahugurwa kumurwi wanjye.
Urubanza rumwe rutazibagirana ni umuterankunga wogoshesha hub. Igitekerezo cya mbere cyari inenge. Isesengura rya Metallurgical ryerekanye ibikoresho byiza. Iperereza ryakozwe ryerekanye ko kunyeganyega kwinshi kuva ku ihuriro ridahwitse ryateje torsional resonance neza na neza na nyirarureshwa. Gukosora ntabwo byari igishushanyo gishya, ahubwo guhuza gukomeye no guhuza laser neza. Uwimura yari kanari mu birombe by'amakara kubera ikibazo kinini cyubukanishi.
Niyo mpamvu urwego rwose rwo gukora rufite akamaro. Uruganda rukora imashini nka QSY itanga serivisi zihuriweho kuva casting kugeza CNC gutunganya itanga inyungu ihamye. Bagenzura byinshi bihinduka. Niba gutsindwa bibaye, isesengura ryibitera ryoroshye biroroshye - ntabwo urimo ukorana nabaguzi babiri batandukanye bashinja inzira zabo. Kubakoresha-nyuma, ibyo gukurikiranwa bifite agaciro, nubwo bitaba buri gihe isoko rihendutse.
Kurangiza Ibitekerezo: Nibidukikije
Noneho, kuvuga kuri an impeller ntabwo bigera gusa kubintu bimwe. Byerekeranye na tekiniki yo gukina ifata imigambi ya hydraulic, imashini imenya neza neza, ibikoresho bikomeza kubaho aho ikorera, hamwe na sisitemu ituyemo. Ibyiza biva mubufatanye hagati ya injeniyeri yubushakashatsi uzi aho ashinzwe hamwe nabafatanyabikorwa bakora bazi uko ibyuma bitwara mugihe ugerageje kubikora. Ubwo bufatanye, bwubatswe mu myaka no gusubiramo bitabarika, nibyo bihindura igishushanyo mubice byizewe bizunguruka. Ntabwo ari byiza, ariko iyo bibaye byiza, sisitemu yose hums.
