Mukamva za 'ndalama zopangira makina opangira uinjiniya,' chithunzi chomwe chilipo chikhoza kukhala ma turbine ang'onoang'ono apamlengalenga. Ndilo mgwirizano wamba, pafupifupi wokhazikika. Koma m'dziko ladothi-pansi-pa-zala la oyendetsa nthaka, ofukula, ndi mabokosi olemetsa olemetsa, ntchitoyo ndi grittier, kulolerana kumakambitsirana mosiyana, ndipo kupanikizika kwa mtengo kumakhala kosalekeza. Sizokhudza kukwaniritsa ungwiro wamalingaliro; ndi za kupereka gawo lomwe limapulumuka katundu wa matani 20 m'dzenje lamatope kwa maola 10,000 popanda kulephera. Kusiyanitsa kumeneko ndi chirichonse.
Chikoka Chosokonekera cha Kuvuta
Makasitomala nthawi zambiri amabwera atakhazikika pa geometry. Yang'anani njira yamkatiyi, iwo amati, akulozera ku chitsanzo cha CAD. Ndipo inde, kupanga ndalama kumapambana pamenepo. Koma pamalumikizidwe a mkono wa boom kapena gulu la hydraulic valve, phindu lenileni silimangopanga zomwe sizingatheke. Ndi umphumphu zakuthupi pansi zimakhudza ndi kutopa. Ndawona mawonekedwe a sera owoneka bwino akumasuliridwa kukhala ma castings omwe adalephera pakuyesa kumunda chifukwa kusankha kwa aloyi kumawonedwa ngati kuganiza motsatira. Njirayi imayamba ndi zinthu, osati nkhungu. Makampani omwe amapeza izi, monga Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., kukhala ndi moyo wautali kusonyeza izo. Zaka makumi atatu mu niche iyi zikutanthauza kuti awona zomwe ma alloys amagwira ntchito. Cholinga chawo pa ma aloyi apadera-Nickel-based for corrosion in slurry pumps, cobalt-based based for wear faces in crusher parts-ndi chizindikiro chodziwikiratu cha zochitika zenizeni, osati bullet point.
Pali malingaliro olakwika opitilirabe akuti kuyika ndalama ndi njira yokonzekera kumaliza. Si. Makamaka zigawo zamakina. Malo a as-cast atha kukhala abwino, koma malo okwererako osindikizira kwambiri? Ayi. Ndipamene mgwirizano ndi CNC Machining umakhala wosakambitsirana. Sitikungopanga kuyimba; tikupanga mawonekedwe apafupi-net-shape kwa makina ovuta. Ndikukumbukira pulojekiti yonyamula zida zam'mlengalenga. Kuponyedwa kunali ndi ma splines amkati ndi matumba opulumutsa kulemera, koma nkhope ya flange imafunikira kulolerana kwa 0.05mm. Choyambitsa chomwe chidawona makinawo ngati vuto la munthu wina adayambitsa zovuta zamalumikizidwe. Sitolo yomwe imaphatikiza kukonza makina mukupanga koyambira koyambira, komwe ndi njira yophatikizika yomwe mumawona pakuchita ngati QSY (malo awo pa. tsngtaocnc.com amalumikiza kuponya ndi makina), amapulumutsa miyezi ya mutu. Ndi malingaliro osiyana.
Kumene Chipolopolo Chimayima (ndi Pomwe Sichikhala)
Izi zimabweretsa mkangano wamuyaya pamakina olemetsa: kuponya nkhungu motsutsana ndi kuponya ndalama. Siutsogoleri wamba. Kwa bulaketi yayikulu, yosavuta, yokhala ndi mipanda yokhuthala, nkhungu ya zipolopolo imakhala mfumu-yachangu, yotsika mtengo. Koma mukakhala ndi ma cores amkati, makoma opyapyala oyandikana ndi zigawo zokhuthala, kapena mufunika kapangidwe kake kazitsulo kazitsulo, kuponya ndalama kumatsogola. Chigoba cha ceramic mkati kuponya ndalama imalola mwatsatanetsatane komanso kuwongolera bwino kuzizirira.
Chitsanzo cha konkire: valani mbale za mutu wobowola miyala. Nkhungu ya zipolopolo inkakhoza kupanga, koma kusasinthasintha kwa kuuma ndi kuthwa kwa mizere yolimba nthawi zonse kunali njuga. Kusinthira kuzinthu zopangira ndalama zamagulu ovala ovutawa kunatipatsa mwayi wodziwikiratu, wofananira. Mtengo wa gawo lililonse unali wapamwamba, koma kuchepetsedwa kwa zolephera zam'munda ndi nthawi yocheperako kwa wogwiritsa ntchito kumapeto kunapanga kupulumutsa. Ndiko kuwerengera komwe kuli kofunikira. Ndi za mtengo wathunthu wa umwini, osati mtengo wamba. Apa ndi pamene zokumana nazo za ogulitsa zimayesedwa—kodi angakutsogolereni ku njira yoyenera, ngakhale siimene poyamba ikuwoneka yotsika mtengo?
Mdyerekezi mu Tsatanetsatane: Kupeza, Kutsika, ndi Zowona
Zojambula zamabuku ndizopanda ntchito. Kwa pivot yopanikizika kwambiri pa chokumba, simumangodyetsa zitsulo; mumawongolera kulimba kuti mupange phokoso lambewu loyenda m'njira zonyamula katundu. Tinaphunzira izi movutikira pa gulu la zida zoyimitsidwa. Zojambula zokongola, zidadutsa X-ray. Koma poyesa kutopa, adasweka pamalo enaake. Kusanthula kulephera kukuwonetsa gulu laling'ono la shrinkage porosity pomwe kupsinjika kwamphamvu kudakwera. Khomo linali lolondola mwaukadaulo kuti mudzaze, koma lolakwika pa moyo wamakina wa gawolo. Tinayenera kukonzanso makina othamanga ndi okwera, kuwonjezera mtengo ndi misa m'madera omwe si ofunikira kuti tikoke kulimbitsa kudutsa m'madera ovuta. Zinagwira ntchito.
Ichi ndiye maziko a ntchito yosasangalatsa. Ndi zitsulo, mphamvu zamadzimadzi, ndi kusanthula kupsinjika zonse zikuyenda mu chipolopolo cha ceramic. Mndandanda wa ogulitsa chitsulo chachitsulo ndi chitsulo chosapanga dzimbiri ndi shopu ya zinthu. Imodzi yomwe ikukamba za kukonza kusungunula ndi nkhungu preheat kwa duplex zitsulo zosapanga dzimbiri kuti ateteze sigma gawo mapangidwe kuwononga chilengedwe migodi gawo - ameneyo ndi mnzake. Chidule chachidule cha QSY chimatchula ntchito yawo pamitundu yonseyi, kuyambira magiredi wamba mpaka kumayiko ena. Izi zikusonyeza kuti amayenera kuthetsa mavutowa, osati kungotsanulira zitsulo.
Kulephera ngati Ntchito Yokakamiza
Simunaphunzire kuyika ndalama pamakina mpaka mutayang'anira zolephera. Chondiphunzitsa changa kwambiri chinali zida zopangira pampu yolemetsa yolemetsa. Inconel 625, masamba ovuta kwambiri. Adadutsa NDT yonse. Miyezi isanu ndi umodzi m'munda, kusweka kowopsa kwambiri. Wolakwa? Zotsalira za chipolopolo. Chidutswa cha pachimake cha ceramic, chotsekeredwa m'ndime yozizirira yamkati yomwe timaganiza kuti ndi yomveka bwino, idapanga malo otentha ndikusintha mawonekedwe ang'onoang'ono akumaloko panthawi yogwira ntchito. Inakhala phata la ming'alu. Kukonza sikunali kuyang'anitsitsa; inali njira yaukali komanso yovomerezeka ya leaching yochotsa pachimake. Tsopano, ndikawunika wogulitsa, ndimamufunsa za njira zawo zochotsera mafungulo akhungu. Yankho limandiuza zambiri kuposa satifiketi yamtundu uliwonse.
Kuphatikiza Ndi Njira Yokhayo Yopita Patsogolo
Kuyang'ana malo pano, tsogolo silili m'nyumba zoyima zokha. Makina opanga ma OEM akufinya nthawi zotsogola ndipo amafuna gawo lonse. Chitsanzo chopambana ndikuphatikizana koyima: kupanga mapangidwe, kuponyera, chithandizo cha kutentha, ndi makina olondola pansi pa denga limodzi, kapena kugwirizanitsa mwamphamvu. Izi zimayendetsa zosintha. Pamene makinawo apeza kupatuka pang'ono pakuponya, amatha kuyankha mwachangu kwa injiniya woyambitsa, ndipo kutsanulira kotsatira kumasinthidwa. Kulekanitsa kwa ntchitozi kumawonjezera masabata ndi zigawo za opacity.
Ichi ndichifukwa chake chitsanzo cha kampani ngati Mtengo wa QSY zimamveka. Ukatswiri wawo wotchulidwa mu zonsezi chipolopolo nkhungu kuponyera ndi kuponya ndalama, pamodzi CNC makina, si mndandanda wa ntchito. Ndiko kuzindikira kuti gawolo ndi lomaliza, osati kuponya. Zaka makumi atatu zitha kutanthauza kuti adachokera ku malo oyambira kukhala opereka mayankho, chifukwa msika udawakakamiza kutero. Simungathe kukhala ndi moyo wautali chonchi mukugwira ntchito yamakina a engineering pongopanga mapatani abwino a sera. Mumapulumuka powonetsetsa kuti gawo lomwe mabawuti pamakina sabwerera.
Choncho, pamene mukufufuza, yang'anani kupyola mawu ofunika. Yang'anani umboni wogwirizanitsa kuthetsa mavuto. Funsani za kachitidwe ka aloyi mu pulogalamu yofananira. Fufuzani nkhani ya kulephera ndi zomwe mwaphunzira. Ukatswiri weniweni mu kuponyedwa kwa ndalama kwa magawo a makina a engineering imakwiriridwa muzinthu zopanda pake, zothandiza, kutali ndi malonjezo otsatsa malonda. Zili mu kulemera kwa kampani ya zaka 30 yomwe ikusinthabe, komanso mu chidaliro chabata chomwe chimabwera chifukwa chokonza zomwe zasweka.
