Ipayipi elincane lensimbi elingaphakathi kodonga lwe-sandblasting umshini

Ipayipi elincane lensimbi elingaphakathi kodonga lwe-sandblasting umshini
Izinyathelo eziyisisekelo zenqubo yokuqhunyiswa kwesihlabathi odongeni lwangaphakathi lwamapayipi ensimbi anobubanzi obuncane (DN200 nangaphansi, ikakhulukazi amadayamitha amancane angama-30-200mm)
Emapayipini ensimbi anobubanzi obuncane, isikhala sodonga lwangaphakathi sincane, kunzima ukubeka ikhanda lesibhamu phakathi nendawo, futhi kunezinkinga ezifana nokuvinjelwa kwesihlabathi / ukugezwa kwesihlabathi / ukushumeka okuhuzukayo. Yonke inqubo kusukela ekukhetheni umshini we-sandblasting odongeni wangaphakathi wamadayamitha amancane, isilawuli sepharamitha, izinkambiso zokusebenza, nokugwema ubungozi idinga ukulawulwa ngokuqinile:
1. Ukukhethwa kanye{1}}nangaphambi kokulungiswa komshini wangaphakathi wokuqhumisa isihlabathi odongeni (imfuneko eyinhloko, ukukhetha okokusebenza okungalungile kuzoholela ekuhlulekeni)
Ukufanisa imishini ekhethekile
Kudingekile ukukhetha isibhamu se-sandblasting sangaphakathi esizinikezele sangaphakathi samadayimitha amancane: khetha imodeli ehambisanayo ngokusho kobubanzi bepayipi, njenge-SY-50 yamadamitha angu-35-75mm, i-SY-100 yama-diameter angu-50-200mm.
Umbhobho kufanele wenziwe ngensimbi ye-tungsten (ukumelana nokugqokwa izikhathi ezi-3-5 kune-boron carbide), futhi umlomo wombhobho owububanzi obungu-φ6-8mm omncane usetshenziselwa amapayipi amancane anobubanzi ukugwema ukuthi ikhanda lesibhamu libhajwe epayipini.
Ukucushwa komthombo womoya: umthamo wokukhipha umoya we-compressor kufanele ube mkhulu noma ulingane no-6m³/min (isibhamu esisodwa), kanye{1}}nesiteji esisodwa sikawoyela{2}}isihlukanisi samanzi (ukunemba kwesihlungi Ngaphansi noma kulingane no-0.1μm) kufanele sihlomeke - amanzi esibange isibhamu esivimbekile, isibhamu esicindezelwe sivale umthombo wokwehluleka ovame kakhulu we-sandblasting encane enobubanzi obuncane.
Ukwelashwa{0}}kwangaphambili kwe-Workpiece kanye ne-abrasive
Ipayipi lensimbi -lokuhlanza ngaphambili: okokuqala, khipha mathupha izingcezu ezinkulu ze-slag yokushisela, isikali se-oxide, nemfucumfucu epayipini ukuze ugweme ukuvimba ikhanda lesibhamu noma ukunwaya udonga lwangaphakathi ngesikhathi sokuqhunyiswa kwesihlabathi.
Isilawuli se-abrasive: khetha 0.3-0.8mm fine-abrasive grained (amabhola ensimbi / brown corundum ayakhethwa, futhi izinhlayiya ezinkulu > 1mm azivunyelwe), i-abrasive kumele yomiswe futhi isefe ukuze kukhishwe uthuli nemfucumfucu - isikhala sangaphakathi samapayipi amancane alinganiselwe, futhi i-particle enkulu izoba mnyama% kuvinjiwe.
2. Ukulawula okunembile kwemingcele yenqubo yomshini we-sandblasting odongeni lwangaphakathi
Ingcindezi yokusebenza: 0.5-0.6MPa (ingcindezi yangempela ku-nozzle ingu-0.35-0.5MPa).
Ijubane elinyakazayo lekhanda lesibhamu: 0.5-1m/min (ukunyakaza okufana kokubuyela emuva), ukushesha kakhulu kuzodala ukugejwa kwesihlabathi esifana ne-strip, ukunensa kakhulu kuzodala ukushona kwesihlabathi okweqile kanye nokugoba kwendawo.
I-angle yesibhamu: i-angle phakathi kwekhanda le-sanding kanye nodonga lwangaphakathi lwepayipi yi-15-30℃: i-angle enkulu kakhulu izobangela isihlabathi esiningi ngokweqile ohlangothini olulodwa, i-angle encane kakhulu izobangela izindawo eziyimpumputhe zokuhlanza.
Isivinini sokuzungezisa amapayipi ensimbi (ukusebenza okujikelezayo): 10-20r/min, kuhlanganiswe nokunyakaza kwe-axial kwekhanda lesibhamu, qinisekisa ukumbozwa komfaniswano ongu-360 degree, gwema amabhande esihlabathi aphuthelwe njenge-spiral.
3. Izinkambiso zokusebenza zomshini we-sandblasting odongeni lwangaphakathi
Ukushintsha ukulandelana (ukhiye wokuvimbela ukuvinjelwa kwesihlabathi)
Qala-phezulu: okokuqala, qinisa umfutho womoya ocindezelwe → bese uvula ivalvu yesihlabathi (ukukhipha okufanayo kwe-abrasive);
Vala shaqa: okokuqala, vala ivalve yesihlabathi → gcina umoya imizuzwana engama-30 → bese umisa umoya: khipha kahle insalela encibilikayo, uthuli, nemfucumfucu ekhanda lesibhamu, umlomo wombhobho, kanye nepayipi elingaphakathi ukuze ugweme isihlabathi esisele ekuvalelekeni nasekuvimbeni.
Izidingo zokusebenza kwekhanda lesibhamu
Ungaphumuli phakathi nendawo: ikhanda lesibhamu elihlala endaweni efanayo imizuzwana engaphezu kwemi-3 lizobangela ukucwiliswa kwesihlabathi okweqile kwasendaweni kanye nokubhobozwa kwepayipi{1}elibiyelwe ngezindonga.
Ukwelashwa{0}okuthunyelwe kufanele kwenziwe
Ngokushesha ngemva kokuqhunyiswa kwesihlabathi: ① sebenzisa umoya ocindezelwe ongu-0.6MPa ukushaya ipayipi ngokugcwele; ② sebenzisa i-endoscope ukuhlola amakhona amapayipi ukuze uqinisekise ukuthi akukho sihlabathi esisele ngaphambi kokudlulisela kunqubo yokumboza.
Ezine. Ukwamukelwa kwekhwalithi nokugwema izinkinga ezivamile
Izindinganiso zokwamukela
Ukuhlanzeka: finyelela ileveli engu-Sa2.5, asikho isikali se-oxide esibonakalayo, ukugqwala, noma i-slag yokushisela odongeni olungaphakathi, ukuchayeka kombala wensimbi okufana nokwensimbi, akunamdwe{1}}njengokusezwa kwesihlabathi esigejiwe;
Ubushelelezi bobuso: I-Ra25-50μm, akukho ukushumeka okulimazayo, akukho mgodi, akukho ukuguga okunezindonga ezincane;
Ukuhlanzeka: akukho ukuthuthumela okusele, uthuli epayipini, akuthinti ukunamathela okulandelayo noma ukuthutha okuphakathi.
Ukugwema izinkinga ezivamile: izinkinga ezivame ukwenzeka
Isibhamu esivinjiwe: Imbangela iwukuba okuswakama kwe-abrasive / izinhlayiya ezinkulu / ukulandelana okungalungile kokuvala shaqa, landela ngokuqinile ukomisa okulimazayo kanye nezinkambiso zokuvala shaqa ukugwema u-99% wezinkinga;
Isihlabathi esigejiwe: ukunyakaza kwekhanda lesibhamu ngokushesha okukhulu ngesikhathi sokusebenza;
Ukushumeka Kwe-Abrasive: Ingcindezi eyeqile kanye nezinhlayiya ezilumayo ezinkulu. Emapayipini amancane-abiyelwe ngezindonga, umfutho wehla ube ngu-0.4-0.5 MPa, futhi izinhlayiya ezilumayo akufanele zidlule ku-0.8mm.
I-Internal Wall Scratches: I-nozzle inamathela odongeni lwepayipi, futhi kukhona izinto zangaphandle ngaphakathi kwepayipi. Ukwelashwa{1}okuphelele kwangaphambili kuyadingeka ukuze uhlanze ipayipi kahle futhi uqinisekise ukuthi umlomo wombhobho uphakathi nendawo.
V. Izidingo Eziyisibopho Ezokuphepha Nezemvelo
Ukuvikelwa Kwabasebenzi: Uthuli olusuka-olusuka ku-sandblasting yamapayipi anobubanzi obuncane kungenzeka kakhulu lunqwabelene ngaphakathi kwepayipi. Ama-opharetha kufanele agqoke izinsimbi zokuphefumula ezinhle futhi anqatshelwe ngokuphelele ukusebenzisa imaski evamile; ukuma ngqo phambi kokuvuleka kwepayipi akuvunyelwe ukugwema izinhlayiya zesihlabathi ukuphindaphinda futhi zilimaze abantu.
Ukulawulwa Kwemvelo: Ipayipi lokungena komoya langaphakathi kanye nesistimu yokususa uthuli kufanele ifakwe (ngevolumu yomoya Enkulu kuno noma elingana no-5000 m³/h). Ipayipi lokususa uthuli kufanele lixhunywe ekugcineni kwe-sandblasting, futhi enye ingxenye kufanele ivalwe ukuze kuvinjelwe ukukhishwa kothuli olungahlelekile; izinhlayiya ezilumayo kufanele ziqoqwe phakathi nendawo futhi akumele zilahlwe ngokungahleliwe.
Ukuphepha Kwezisetshenziswa: Igeyiji yokucindezela kanye nevalvu yokuphepha ye-compressor yomoya kufanele ilinganiswe nyanga zonke, futhi ipayipi le-sandblasting kufanele lihlolwe ukuze ligqokwe njalo ukuze kugwenywe{0}}ukuqhuma nokulimala okuphezulu.
