I-China Chemical Excnsion Bolt

Muva nje, kuvame kakhulu ukuthi ngizwa izicelo ezihlobeneAma-Bolts embonini yamakhemikhali, ikakhulukazi nalabo enzelwe izimo ezinzima zokusebenza. Abakhiqizi abaningi be-oda ama-fasteners, ancike kwizici ezijwayelekile - insimbi, anti -corrosion. Kepha iqiniso livame ukuba nzima ngokwengeziwe. 'Nje' i-chemical bolt 'akwanele. Bahlangabezana nezimo lapho i-fastener ekhethiwe yehluleka ngokushesha, noma ngabe zonke izincomo zokusebenzisa ziyabonakala. Ngakho-ke, nganquma ukuhlanganyela isipiliyoni salokho esikubonayo, yeka ukuthi kwenziwa amaphutha, nokuthi ungakugwema kanjani lokhu. Akukona ngombono, kepha mayelana nezibonelo ezithile ezabhekana nazo ngomsebenzi, futhi ngalokho okusebenzayo nokuthi yini engeyena.

Izinselelo eziyisisekelo lapho ukhetha ama-fasteners embonini yamakhemikhali

Iphuzu lokuqala nelibaluleke kakhulu, kunjalo, imvelo enolaka. Amakhemikhali amakhemikhali, ama-acid, alkalis - ayakwazi ukubhubhisa ama-alloys ahlala isikhathi eside kakhulu. Insimbi engenacala 'ayigciniwe ngaso sonke isikhathi, ikakhulukazi uma kukhulunywa ngokuxhumana nezinto ezihlanganisiwe isikhathi eside. I-Aisi 316 ihlala ikhethwa, kepha leli yindawo yokuqala. Kuyadingeka ukubheka ukwakheka okuthile kwamakhemikhali kwemvelo. Kwesinye isikhathi ngisho nezinga eliphakeme lokuvikelwa akuqinisekisi insizakalo ende. Sisebenza ngandlela thile ngebhizinisi elisebenzisa ama-bolts angama-316 ukuxhumana ne-sulfuric acid. Ezinyangeni eziyisithupha kamuva, bagcwala ngokusobala, naphezu kokuthobeka okubonakala bekhona ngezindlela zobuchwepheshe. Kwavela ukuthi iphuzu ligxile kakhulu kokungcola kwe-acid, okusheshise ukugqwala. Ezimweni ezinjalo, kufanele ushintshele kuma-alloys akhethekile, ngokwesibonelo, i-hastelloy noma infolnel.

Enye into ebalulekile umbuso wokushisa. Ngezinqubo zamakhemikhali, amazinga okushisa aphezulu futhi aphansi asetshenziswa kaningi, okunengcindezi eyengeziwe kuma-fasteners. Emazingeni okushisa aphezulu, izinto zokwakha ziyandiswa, ezingaholela ekubeni buthaka ukuxhumana. Emazingeni okushisa aphansi, insimbi iba buthaka ngokwengeziwe futhi ngaphansi kokubhujiswa. Lapho ukhetha ama-bolts, kuyadingeka ukubheka ububanzi bokushisa okusebenzayo bese ukhetha izinto ezigcina izakhiwo zabo kulezi zimo. Akunakwenzeka ukubukela phansi umphumela womjikelezo we-thermal - ukufudumeza okuhlala njalo nokupholisa kwakha izingcindezi ekuxhumekeni, okugcina kuholela ekubhujisweni kwayo.

Ngaphezu kokuhlukumezeka kwamakhemikhali kanye nokwehluka lokushisa, kuyadingeka ukubheka imithwalo yemishini. Isibonelo, ukudlidliza kwemishini, isibhamu, isivinini sokujikeleza okuphezulu - konke lokhu kungaholela ekubeni buthaka ngokuxhumeka. Lokhu kuyiqiniso ikakhulukazi kwimishini emikhulu, efana nama-reactors namaphampu. Kubalulekile ukukhetha usayizi ofanele nohlobo lwama-bolts, futhi usebenzise ama-bearings akhethekile nezimpawu zokugcina, ezinikezela ngokulungiswa okuthembekile kokuxhumeka.

Izinhlobo zamakhompiyutha nezici zawo

Uhlobo lokuxhumeka luyinto ebucayi. Akuhlali ngokwanele ukumane uqinise i-bolt futhi uthole ukuxhumana okuthembekile. Imvamisa, ukulungiswa okwengeziwe kuyadingeka, ngokwesibonelo, ngosizo lwama-washers, amantongomane anezifo zentambo, noma ama-sealants akhethekile. Isibonelo, ukuxhuma izakhi ze-reactor ngaphansi kwengcindezi ephezulu, amakhompiyutha anamathela ajwayele ukusetshenziswa, okunikeza ukuqina nokwethembeka.

Sivame ukuhlangana nenkinga yokukhethwa okungafanele kwezinjongo. Vele i-washer eyisicaba ayihlali ilungele imboni yamakhemikhali. Ukuhlanza ngongqimba noma amawashi okugeza ajwayele ukusetshenziswa, okwenziwe ngezinto ezikhethekile ezingamelana nolaka lwamakhemikhali. Musa ukungonga ezihlathini eziphezulu, ngoba zidlala indima ebalulekile ekuqinisekiseni ukwethenjwa kokuxhumeka.

Ngaphezu kwalokho, kubalulekile ukukhetha umzuzu wokuqiniseka ofanele. Umzuzu onamandla ngokweqile ungaholela ekubhujisweni kwentambo noma ekuguqukeni kwezingxenye ezixhunyiwe. Iphuzu elincane kakhulu likuholela ekubuthakathaka kokuxhumeka nokubhujiswa kwalo okuphelele. Lapho uqinisa ama-bolts embonini yamakhemikhali, okhiye bakwaDynamometric bavame ukusetshenziselwa ukuqinisekisa isikhathi esifanele sokuqinisa. Kepha ngisho nokhiye we-dynamometric, kuyadingeka ukubheka izici zezinto ezibonakalayo nohlobo lwe-compound. Isibonelo, ukulungisa imicu, izinto zokuthambisa ezikhethekile zivame ukusetshenziswa, okunciphisa ukungqubuzana futhi kunikeze iphuzu elinembe kakhudlwana.

Izibonelo Ezisebenzayo Namaphutha

Ngabona amacala amaningi lapho bekhethaAma-Bolts embonini yamakhemikhali, ukugxila kuphela ekubukekeni nasentengo. Ngenxa yalokho, ngemuva kwesikhathi esithile bekufanele ngithathe indawo yawo, okuholele ekukhiqizeni okulula kanye nezindleko ezingezekile. Enye yezibonelo ezinhle kakhulu i-oda lama-bolts avela kwinsimbi evamile yekhabhoni ngokuxhuma izakhi ze-reactor zamakhemikhali. Ezinyangeni ezimbalwa kamuva bahlasela, okwaholela ekuvuzeni okuvuzayo kanye nemiphumela emibi.

Enye iphutha elivamile ukukhetha okungalungile kwezinto ezibonakalayo. Abakhiqizi abaningi bakhetha ama-bolts ensimbi angenasici, bekholelwa ukuthi kumelana nanoma iyiphi imvelo yamakhemikhali. Kepha lokhu akunjalo. Akuyona yonke imikhiqizo yensimbi engenasici amelana nokuhlaselwa kwamakhemikhali. Isibonelo, ama-bolts enziwe ngensimbi e-auntenitic engagqwali (ngokwesibonelo, i-Aisi 304) ayilungele ukuxhumana ne-sulfuric acid. Ezimweni ezinjalo, kuyadingeka ukusebenzisa ama-bolts kusuka kuma-alloys azinzile, njengensimbi engenacala (ngokwesibonelo, i-aisi 2205) noma i-hastelloy. Lapho ukhetha okuqukethwe, kubalulekile ukubheka hhayi indawo yamakhemikhali kuphela, kodwa futhi nokushisa nengcindezi.

Enye inkinga ukufakwa okungoni kwezimpawu ezimbi. Izimpawu kufanele zenziwe ngezinto zokwakha eziphikisana nokuvunyelwa kwamakhemikhali kanye namazinga okushisa aphezulu. Ukukhethwa okungalungile okukhethiwe noma okufakiwe kungaholela ekuvuzweni kwama-reagents kanye nomonakalo kwimishini. Musa ukungonga eziMpulini, ngoba badlala indima ebalulekile ekuqinisekiseni ukuqina kokuxhumeka.

Izincomo Zokukhethaama-fasteners amadivayisi wamakhemikhali

Uma uhlela ukuthengaAma-Bolts embonini yamakhemikhali, Ngincoma ukuxhumana nabahlinzeki abathembekile abanokuhlangenwe nakho okuhlangene nemboni yamakhemikhali. Kubalulekile ukuhlinzeka umphakeli ngayo yonke imininingwane edingekayo mayelana nemvelo yamakhemikhali, izinga lokushisa, ingcindezi kanye nengcindezi yemishini. Zizwe ukhululekile ukubuza imibuzo futhi udinga izitifiketi zezinto zokwakha. Qiniseka ukuthi ama-bolts ahlangabezana nezidingo zamadokhumenti alawulayo kanye namazinga wekhwalithi.

Kubalulekile ukuthi umphakeli anganikezela kuphela ama-bolts, kodwa nakwamanye ama-fasteners, kanye nezinto zokwakha, njengama-washers, amantongomane, izimpawu zokuthambekela. Inketho ekahle ngumphakeli onganikeza isixazululo esibanzi sephrojekthi yakho. I-Handan Zitai Fetacterer Manoufacting Co, Ltd. (https://www.zitaichassens.com) ibisebenza emakethe isikhathi eside futhi inganikeza ibanga elibanziama-fasteners akhethekileIlungele izimo ezinzima kakhulu zokusebenza.

Ekuphetheni, ngifuna ukusho ukuthi ukukhethwa kwama-fasteners embonini yamakhemikhali kuwumsebenzi onzima odinga indlela ecophelela futhi abalale izici eziningi. Ungagcini kuma-fasteners, ngoba ukuthembeka kwawo kuncike ekuphepheni nasekusebenzeni kwawo wonke umkhiqizo.

Ukubaluleka kokulawulwa kwekhwalithi kanye nesitifiketi

Ngaphezu kokukhetha impahla efanele nohlobo lokuxhumeka, kubalulekile futhi ukulawula ikhwalithi yokukhiqizwa kwama-fasteners. Ama-bolts ampofu -Qondise angahle abe nezinkinga zentambo, i-geometry engajwayelekile noma ayihambelani nezimpawu ezimenyezelwe. Ngakho-ke, kuyadingeka ukuthi ukhethe abahlinzeki abanohlelo lokulawula ikhwalithi futhi banikeze izitifiketi zemikhiqizo yabo. Naka ukutholakala kwezitifiketi zokuhambisana namazinga aphesheya, njenge-ISO 9001. Lesi isiqinisekiso sokuthi imikhiqizo ihlangabezana nezidingo zekhwalithi nokuphepha.

Okunye okubalulekile kulawulwa ngokuhambisana nobuchwepheshe bokukhiqiza. Ukukhiqizwa kwama-fasteners kufanele kwenziwe ngokuya ngemithethonqubo yezobuchwepheshe kanye namazinga ekhwalithi. Ukukhiqizwa okungekuhle kungaholela ekulimaleni kwentambo, ukunganakwa kosayizi noma ukwelashwa okungafanele komhlaba. Ngakho-ke, kuyadingeka ukuthi ukhethe abahlinzeki abanemishini yesimanje nabasebenzi abafanelekayo. Ukucwaningwa kwamabhuku njalo kwezinqubo zokukhiqiza kuzosiza ekuboneni nasekunciphiseni izinkinga ezingaba khona.

Ungakhohlwa ngesidingo sokufeza izinto zokuhlola. Ukuhlolwa kukuvumela ukuthi uhlole ukubizwa kwemikhiqizo ngezimpawu ezimenyezelwe futhi ukhombe iziphambeko ezingaba khona. Ukuhlolwa kungafaka ukuhlola, ubulukhuni, ukugqokwa kokuphefumula nokuphikiswa kokugqwala. Imiphumela yokuhlola kufanele ibhalwe phansi futhi iyatholakala ukuze ijwayele ukujwayela.
