Iwasha eliyisicaba elinamanzi ashisayo kufanele lithengwe njengengxenye ehlanganisiwe echaziwe, hhayi nje njengediski yensimbi enosayizi ongu-M. Ukucaciswa okusebenzisekayo kukhomba indinganiso yobukhulu nochungechunge, usayizi wegama, amadayamitha angaphakathi nangaphandle, ukujiya, izinga lomkhiqizo, ukuqina noma isidingo somshini, impahla eyisisekelo, imfuneko yokwemboza kanye nebhawodi, inathi nendawo yokuthwala okuzosetshenziswa ngayo iwasha. Umthengi kufanele futhi achaze ukuthi izilinganiso zamukelwa ngaphambi noma ngemva kokumbozwa nokuthi yimaphi amarekhodi okuhlola okufanele ahambisane nokuthunyelwa. Lokhu kuvimbela amawasha ahlukene ngokobuchwepheshe ukuthi abonakale elingana kukhotheshini futhi kunciphisa ubungozi bokuphazamiseka kwembobo, ukufakwa kwenkomishi yewasha, ukuthwala okungekuhle noma ukuvikela ukugqwala okungaguquki.
Okwenziwa iwasha eliyisicaba endaweni ehlangene
Iwasha eyisicaba inikeza indawo ethwalayo elawulwayo ngaphansi kwekhanda lebhawodi noma nati. Ingakwazi ukusabalalisa ingcindezi yokuxhumana, ivikele indawo exhunyiwe futhi ibhuloho imvume ezungeze imbobo ye-bolt. Ayikhiyi ngokuzenzakalelayo ilunga, ilungise ubude bebhawodi obungafanele noma inxephezele indlela yokuqinisa engalungile. Leyo misebenzi incike ekuhlanganiseni okuphelele.
Lo mehluko ubalulekile ngesikhathi sokuthola usizo. Umthengi uphequlula a uhla lwewasha oluyisicaba olushisayo-dip ingase ithole imikhiqizo eminingana elingana nobubanzi obufanayo bebhawodi kodwa ihluke ngobubanzi obungaphandle, ukushuba, ubulukhuni, ukubekezelelana nokunamathela. Igama eliqokiwe liyisihlungi sokuqala kuphela.
Izinto ezixhunyiwe zibaluleke ngokufanayo. Iwasha yochungechunge oluvamile ingase ifaneleke endaweni ethwalayo eqinile, enosayizi olungile, kodwa impahla ethambile noma imbobo yokukhipha usayizi omkhulu ingadinga ububanzi obuhlukile bangaphandle noma ukujiya. Leso sinqumo singesomklamo ohlanganyelwe; akufanele ishiywe ekwahluleleni okubonakalayo ngesikhathi sokufakwa.
Izidingo ezihlukene zobukhulu, zemishini kanye nezokunamathela
Izindinganiso zewasha azilawuli zonke izakhiwo ezifanayo. Izinga le-dimensional lichaza ubudlelwano bejometri nosayizi. Ukucaciswa komshini kukhuluma ngezakhiwo ezinjengokuqina kanye nokufaneleka kwewasha ukuthi isetshenziswe namakilasi ezindawo zokubopha okuthile. Incazelo ye-hot-dip galvanizing ilawula inqubo yokumboza kanye nezidingo zokwamukelwa. Ukubhala inombolo eyodwa kuphela evamile ku-RFQ kungase kushiye izingxenye ezibalulekile zokuthenga zingachazwanga.
| Isendlalelo sokucaciswa | Lokho elivame ukukulawula | Lokho i-RFQ esadinga ukukusho |
| Iwasha indinganiso yobukhulu | Uchungechunge lokuzisholo, ububanzi bangaphakathi, ububanzi obungaphandle, ukujiya kanye nebanga lomkhiqizo | Ukuqokwa okuqondile, usayizi, ukubuyekezwa kanye nanoma ibuphi ubukhulu bangokwezifiso obuvunyelwe |
| Imfuneko yemishini | Ukuqina noma isigaba sempahla nokuhambisana nomhlangano wokubhowula | Amamaki e-bolt namantongomane, isimo sesevisi kanye nobufakazi obudingekayo |
| Imfuneko yokumboza | Inqubo ye-hot-dip galvanizing, ukujiya kokugqoka, ukuqeda kanye nokuhlolwa okusebenzayo | Izinga le-Coating, amasampula, imikhawulo yokubukeka kanye nenqubomgomo yokulungisa |
| Umdwebo wephrojekthi noma i-oda lokuthenga | Ukucushwa okuqondene nohlelo lokusebenza kanye nobubanzi bezohwebo | Inani, ukupakisha, imibhalo, ukumakwa, ukuchezuka kanye nesisekelo sokudiliva |
I-GB/T 97.1-2002 ihlanganisa amawasha angenalutho e-standard-grade, product-grade-A futhi ihlukanise amakilasi okuqina ukuze asetshenziswe ngamakilasi ahlukene e-bolt, screw and nut. I-ISO 7089 ikhuluma nejiyomethri ehambisanayo yochungechunge olujwayelekile lomkhiqizo-grade-A kumongo wamazwe ngamazwe. Lezi zithenjwa zisiza ukukhomba umndeni womkhiqizo, kodwa umthengi kufanele asho izinga eliqondile elidingwa iphrojekthi esikhundleni sokuphatha i-GB/T ne-ISO eqokomisayo njengokushintsheka ngokuzenzakalela.
Umngcele phakathi kwemishini nokugqwala ubaluleke ngendlela efanayo. I-ISO 898-3 icacisa izakhiwo zemishini nezomzimba zamawasha ayisicaba, kodwa ayikucacisi ukumelana nokugqwala. Ngakho-ke, izidingo zokugqoka i-zinc eshisayo kufanele zichazwe ngokwehlukana. I-ISO 10684 ngokuyinhloko imboza ama-hot-dip spun coatings ezixhunyweni ezinentambo futhi ivumela izinhlinzeko zayo ukuthi zisetshenziswe ezingxenyeni ezingenantambo njengamawasha; I-ASTM F2329/F2329M iphinde imboze ngokusobala izigqoko ze-zinc ezishisayo kumawasha. Idokhumenti yephrojekthi esebenzayo inquma ukuthi yimuphi umzila ongowohlelo.
Qinisekisa i-diameter yangaphakathi, ububanzi bangaphandle nobukhulu njengesethi
I-diameter yangaphakathi ilawula imvume yokuhlanganisa eduze kwe-bolt shank nanoma yikuphi ukunamathela ku-fastener yokukhwelana. Ukucaciswa okuncane kakhulu kungabangela ukuphazamiseka noma ukulimala ngesikhathi sokuhlanganiswa. Ukuvunyelwa ngokweqile kunciphisa indawo yokuthwala ephumelelayo yewasha eduze komgodi futhi kungaba yinkinga ikakhulukazi uma umsebenzi wokusebenzela usuvele unomsebenzi omkhulu wokuvula.
Ububanzi bangaphandle bubeka indawo lapho umthwalo we-clamp udluliselwa endaweni exhunyiwe. Ubukhulu buthonya ikhono lewasha lokuhlala phansi ngokwanele ngaphansi kwalowo mthwalo. Lawa manani amabili ayasebenzisana: ukukhulisa ububanzi obungaphandle ngaphandle kokucabangela ukujiya nobulukhuni kungakhiqiza iwasha egobayo noma izinkomishi esikhundleni sokuhlinzeka indawo enebheyili ezinzile.
Yingakho isicelo se-"M16 flat washer," isibonelo, singaphelele. Umthengi udinga uchungechunge olujwayelekile noma ubukhulu obuthathu obuqondile, usayizi wembobo yebhawodi endaweni yokusebenza kanye nezinto ezingaphansi kwewasha. Uma iphrojekthi isebenzisa izimbobo eziboshiwe, ishidi elincanyana, ukhuni, insalela, ama-coatings noma ezinye izindawo ezicindezelayo, unjiniyela onomthwalo wemfanelo kufanele aqinisekise ukuthi iwasha evamile ihlala ifanelekile yini.
Ukuqina kwewashi kufanele kuhambisane nokuhlanganiswa kwamabhawudi
Iwasha ingalingana ngobude futhi iqhubeke ingafanelekile ngokomshini. Ngaphansi kwebhawodi elayishwe kakhulu noma nati, iwasha ethambile kakhulu ingase ihlehle, idle noma ishumeke endaweni exhunyiwe. Lokho kunyakaza kunganciphisa ukuzinza kwejoyinti eliboshwe nakuba ibhawudi ngokwalo lihlangabezana nesigaba sempahla esicacisiwe.
Ukuqina kwewashi noma ikilasi lempahla kufanele libuyekezwe ngebhawodi namabanga amantongomane, lingakhethwa ngokuzimela. I-GB/T 97.1-2002 ihlukanisa amawasha angu-200 HV kanye nama-HV angu-300 kumabanga ahlukene wamandla okubopha ukukhwelana. Imininingwane yamazwe ngamazwe noma yephrojekthi ingase iveze imfuneko ngendlela ehlukile, ngakho i-RFQ kufanele ihlonze ukuhlangana okuphelele nobufakazi obudingekayo esikhundleni sokucela umphakeli ukuthi asho ubulukhuni kusayizi wewasha.
Isitifiketi sokumboza akufakazeli ubulukhuni, futhi umphumela wokuqina awufakazi ukuhambisana kwe-coating. Ukugcina lawo marekhodi ehlukene kwenza ukubuyekezwa kwekhotheshini nokuhlola okungenayo kucace kakhudlwana.
I-hot-dip galvanizing ishintsha ngaphezu kokubukeka
I-hot-dip galvanizing ihlinzeka nge-zinc coating phezu kwendawo yensimbi, kodwa ukucaciswa kokuthengwa kwempahla kufanele kuchaze ukuthi lokho kunamathela kwamukelwa kanjani. Ukuqina kwe-coating, ukumboza, ukuqeda, ukunamathela, ukulungiswa kwendawo kanye nokuphathwa kwe-zinc eyeqile kungathinta kokubili ukusebenza kokugqwala nokuhlanganiswa. Iwasha ekhanyayo noma ebukeka iyunifomu ayilona ubufakazi obanele ngokwayo.
Ngenxa yokuthi i-zinc yengeza izinto endaweni, ubukhulu nokufaneleka kufanele kuhlolwe esimweni sokulethwa. I-zinc eyeqile emgodini wewasha noma ebusweni obuphethe ingase iphazamise ukuhlanganisa noma ivimbele ukuthintana okugcwele, okuzinzile. I-Centrifuging noma enye indlela yokukhipha elawulwayo ivame ukusetshenziselwa i-hardware encane ukukhipha i-zinc yamahhala, nokho umthengi usadinga uhlelo lokuhlola okuvunyelwene ngalo.
Ukukhethwa kwe-coating kufanele futhi kufane nomhlangano wonke. Iwasha enamathayela ediphu ashisayo ebhanqiwe nesiphetho esingahambelani nesibophelelo ingadala ukukhathazeka kokufakwa noma ukuqina. I-oda kufanele licacise isistimu yokuhlanganisa ibhawodi, inathi kanye newasha ndawonye, okuhlanganisa noma yimiphi imithetho yephrojekthi yokuhambisana kokumboza nokulungisa inkundla.
Hlola ubukhulu bomkhiqizo wangempela ngaphambi kokucela ikhotheshini
I-Wotu ibaliwe GB/T 97.1 grade-A iwasha flat isebenzisa i-hot-dip galvanized finish iyonke futhi inikezwa ngosayizi we-M6–M64. Ulwazi lomkhiqizo luphinde lufake ohlwini i-zinc plating eyi-blue-white, i-zinc plating yombala ne-oxide emnyama, kanye nokusekelwa kobukhulu obungajwayelekile. Abathengi kufanele basho isiphetho esidingekayo ngokusobala ngoba lezi ezinye izinhlelo zokumboza ezihlukene, azizona izincazelo ezishintshekayo.
Irekhodi lomkhiqizo elifanayo lithi isikhwama esilukiweyo esingu-25 kg noma ukupakishwa kwebhokisi lokuthekelisa, ukugoqwa kwephalethi ukuze kulayishwe ngokugcwele kanye nokusekelwa kwamalebula angasese. Le mininingwane ingaba wusizo kuma-oda okusabalalisa kanye namaphrojekthi, nakuba ikhotheshini yokugcina kusafanele iqinisekise isibalo seyunithi noma isisindo sengqikithi ngephakheji, okuqukethwe ilebula, imikhawulo yephalethi kanye nokulandeleka kwenkatho. Incazelo yephakheji ye-25 kg iyodwa ayilitsheli ithimba elemukelayo ukuthi mangaki amawasha esitsheni ngasinye.
Ukuhlola kufanele kuxhumanise isimangalo ngasinye nobufakazi
Ukuhlola okungenayo kusebenza kahle kakhulu uma kulandela ukucaciswa okufanayo okusetshenziselwa ikhotheshini. Amasheke anobukhulu kufanele amboze ububanzi obuvunyelwene bangaphakathi, ububanzi obungaphandle nobukhulu, kanye nokucaba, ama-burrs nanoma iyiphi i-geometry ekhethekile. Izilinganiso zidinga isisekelo samasampula esishiwo futhi kufanele zibonise ingxenye eboshiwe, elethiwe uma kuyilokho okudingwa umdwebo.
Ukuqinisekisa ngomshini kungase kuhlanganise imiphumela yokuqina noma amanye amarekhodi adingwa yizimiso ezilawulayo. Ubufakazi bokunamathela bungabandakanya izilinganiso zokuqina kokuqina, ukubukeka nokuhlolwa kokumboza, ukuhlola ukunamathela noma okunye ukuhlola okuchazwe yizinga elikhethiwe lokugqama. Umthengi akadingi sonke isitifiketi esingaba khona kuwo wonke ama-oda; iphakethe ledokhumenti kufanele lilingane nesicelo futhi kuvunyelwene ngaphambi kwentengo.
Ukulandeleka kuvala iluphu. Amalebula ebhokisi, isikhwama noma i-pallet kufanele axhumanise amawasha alethiwe ku-oda lokuthenga, usayizi, isiphetho kanye nendawo yokukhiqiza. Ngaphandle kwaleso sixhumanisi, umbiko wokuhlola olungile ungaba nzima ukuhlotshaniswa nokokusebenza okufinyelela isayithi.
Qhathanisa izingcaphuno kuphela ngemva kokuba ububanzi bobuchwepheshe buqondaniswe
Okunikezwayo okubili kungasebenzisa incazelo efanayo yewasha ngenkathi kufakwa amanani emikhiqizo ehlukene. Umphakeli oyedwa angase acaphune iwasha yosayizi ojwayelekile enokuhlolwa okuyisisekelo kohwebo; enye ingase ihlanganise isigaba sokuqina esichaziwe, izilinganiso ezilawulwayo zangemuva kokumboza, izivivinyo zokumboza, amabhokisi okuthekelisa kanye namarekhodi enkatho. Intengo yeyunithi ephansi ayinakuqhathaniswa ngokuqondile kuze kube yilapho sekumenyezelwe lo mehluko.
Ukubuyekezwa kwengcaphuno okuwusizo kwehlukanisa imibuzo emine:
- Ingabe iwasha enikezwayo iyafana nezinga eliceliwe lobukhulu obuceliwe, usayizi kanye nebanga lomkhiqizo?
- Ingabe ubulukhuni bayo noma impahla ewumshini iyahambisana nebhawodi elishiwo kanye nokuhlanganiswa kwamantongomane?
- Ingabe ububanzi bokwenza uthayela busekelwa ubufakazi obudingekayo bokumboza kanye nokulingana kwangemuva?
- Ingabe ukuhlolwa, ukupakishwa, ukumaka kanye nemibhalo kufakiwe enanini elicashuniwe kanye nesikhathi sokuhola?
Noma yiliphi izinga elishintshayo, inqubo yokumboza, ubukhulu, isigaba sokuqina noma ukukhishwa kwedokhumenti kufanele kuvele ohlwini lokuchezuka. Ukuthula akusona isiqinisekiso. Ikhotheshini iba wusizo lapho ubunjiniyela nokuthenga kungabona ngqo lokho okuzohlinzekwa.
Lungiselela i-washer RFQ abahlinzeki abangayiphendula ngokuqondile
Bandakanya izinga lewasha kanye noshicilelo, usayizi wegama, ububanzi bangaphakathi, ububanzi bangaphandle, ukujiya, izinga lomkhiqizo, ubulukhuni noma isigaba sendawo, impahla eyisisekelo, imfuneko yokufaka ama-galvanizing ashisayo, amamaki okukhwelana namantongomane, impahla yokusebenza kanye nesimo sembobo. Engeza inani, ukupakisha, ukumaka, ukuhlolwa, idokhumenti kanye nezidingo zokulethwa. Uma iwasha yangokwezifiso idingeka, namathisela umdwebo olawulwayo futhi ukhombe ukuthi ibuphi ubukhulu nokubekezelela okuhlukile kokujwayelekile.
Cela umphakeli ukuthi abuyisele igama elinikeziwe, izilinganiso zangemuva kokumboza, imfuneko yomshini, izinga lokunamathela, ububanzi bokuhlola, isisekelo sokupakisha nakho konke ukuchezuka. Thumela lokho okokufaka kwephrojekthi nge-Wotu ifomu lokubuza nge-fastener lobuchwepheshe. Ngezimo ezihlanganyelwe kanye nobufakazi bokwamukela bulungisiwe kuqala, ukuqhathanisa kwezohwebo kungagxila kububanzi bokunikezwayo obulingana ngempela.
