Uzibona kuyo yonke indawo xa uqala ukukhangela - kulwakhiwo, koomatshini, nakwifenitshala ye-DIY. Imisonto enemisonto. Uninzi lwabantu, kwanabanye abakurhwebo, bacinga ngabo njengeebholiti ezinde. Yimpazamo yokuqala leyo. Ziyinxalenye esisiseko, kodwa ukusetyenziswa kwazo akukho nto ilula. Umtyholi ukwiinkcukacha: ibakala lezinto eziphathekayo, uhlobo lwentambo, isambatho, kunye ne-fiziksi engaxoleliyo yoxinzelelo kunye nokucheba. Ndizibonile iiprojekthi apho ukhetho olungalunganga apha luye lwaba yeyona ndawo yokusilela, hayi i-actuator entle okanye umqadi wentsimbi obizayo.

Izinto eziphathekayo kunye neBanga: AyisiyoNsimbi nje

Ukuqala ngezinto ezisisiseko, izinto eziphathekayo zizinto zonke. Intonga yentsimbi ye-A36 ilungile ukuxhoma umbhobho okanye ukubopha okungabalulekanga. Kodwa ngoku uzisa umthwalo oguqukayo, ukungcangcazela, okanye imeko-bume eyonakalisayo, ukwilizwe elahlukileyo. Ndiyasilela uku iintonga ezinemisonto yenziwe nge-ASTM A193 B7 okanye i-B8 kwizinto ezininzi ezisetyenziswa kwimizi-mveliso. I-B7 yintsimbi ye-alloy, icinyiwe kwaye inomsindo, inika amandla aphezulu - cinga ngeentonga zokubopha isitya soxinzelelo okanye i-anchoring enzima yesakhiwo. I-B8 luhlobo olungenastainless, ludla ngokuba ngama-304 okanye ama-316, kwizityalo zekhemikhali okanye kukulungiswa kokutya. Umahluko kwiindleko ubalulekile, kodwa kunjalo nesiphumo sokusilela.

Ndikhumbula umsebenzi wokubuyisela imali kwiyunithi yokulungiswa konxweme. I-specpe ifuna iirodi zentsimbi zekhabhoni zokonga iindleko. Kwisithuba seenyanga ezili-18, ukuqhekeka kwe-chloride-induced corrosion cracking yaqala ukubonakala. Kuye kwafuneka ukuba senze ukuvalwa ngokupheleleyo endaweni nge-316 engenasici. Ugcino lokuqala luxabisa ngokuphindwe kalishumi kubasebenzi bakaxakeka kunye nexesha lokuphumla. Sisifundo ongalibali eso. I-coating, i-hot-dip galvanizing versus plating mechanical, nayo idlala indima enkulu kubomi obude, kungekhona nje ukubonakala.

Emva koko kukho ukumakishwa kwebakala, okanye ukunqongophala kwalo. Umthengisi obekekileyo uya kuyisonga ngokucacileyo kwintonga. Ngokuba amandla aphezulu iintonga ezinemisonto, ukhangela imigca emithathu yeradial ye B7. Akukho manqaku? Yiphathe njengomgangatho ophantsi kwaye ungabheji iprojekthi yakho kuyo. Apha kulapho ukukhangela kumvelisi okhethekileyo kwindawo yemveliso egxininisiweyo kunengqiqo. Umzekelo, inkampani efana ne-Handan Zitai Fastener Manufacturing Co., Ltd., eseYongnian-esona siseko se-fastener esona sikhulu saseTshayina- sinesiseko sokulawula oku ukusuka kwibhilethi ukuya kwimveliso egqityiweyo, enganikwanga nabarhwebi ngokubanzi.

I-Tread Engagement kunye neVoodoo yokusasazwa koMthwalo

Nantsi intloko esebenzayo: ingakanani intambo yokuzibandakanya eyaneleyo? Incwadi yesikhokelo iphinda-phindwe kayi-1.5 ubukhulu. Okwenyani kumdaka. Ukuba uqhagamshela kwizinto ezithambileyo ezifana ne-aluminiyam okanye ukuphosa, udinga ngakumbi. Umthwalo awuthwalwanga ngokulinganayo kuyo yonke imisonto; imisonto yokuqala embalwa ebandakanyekayo ithatha ubunzima bayo. Ndibale iindibano kuphela ukuze nditsalelwe umnxeba wetekhnoloji isithi umngxuma ocofayo ukhutshiwe. Rhoqo, umba yayingeyiyo imathematika yam, kodwa umgangatho womngxunya ocofayo-ungaphantsi, ungekho kwi-axis, okanye ugcwele iichips.

Iqhinga leendawo zokungcangcazela okuphezulu: sebenzisa i-jam nut. Qinisa i-nut yokuqala ukucacisa, uze uqinise i-nut yesibini kuyo. Kubonakala ngathi yinto encinci, kodwa ithintela ukukhulula ekulayisheni umjikelo ngcono kuneendlela ezininzi zokutshixa ezinqabileyo. Kwakhona, soloko usebenzisa iwasha. Kubonakala ngathi kucacile, kodwa ndiyibonile ukuba iyatsiba. Iwasha isasaza umthwalo obambeleyo kwaye inqande i-nati ekugrumbeni kumphezulu, nto leyo inciphisa kakhulu amandla okubamba asebenzayo.

Sika intambo vs. intambo eqengqelekayo - enye i-nuance. Imisonto eqengqelekayo yomelele kuba ukuhamba kweenkozo zentsimbi kulandela imo yomsonto, akunqunyulwa kuyo. Kuso nasiphi na isicelo esibalulekileyo, gxininisa kwimisonto eqengqelekayo. Uyakwazi ukubona ngesiphelo esigudileyo, esitshisiweyo kunye nobukhulu obuncinci bedayamitha kwincam zentonga.

Iinyani ezikwiSiza kunye nePragmatism yokuBonelwa

Kwintsimi, awufane ube nentonga egqibeleleyo ubude kunye nomsonto. Usika kwaye uthunge kwisiza. Idiyiti esemgangathweni ixabisa ubunzima bayo kwigolide. Ixabiso eliphantsi liya kuvelisa intambo ethambileyo ebeka esichengeni amandla. Sigcina iseti yentsimbi enesantya esiphezulu iyafa kunye nomsonto osebenza ngamandla wemisebenzi efuna ngaphezulu kweentonga ezimbalwa. Ngentsimbi engenastainless, hamba kancinci, sebenzisa ioyile yokusika eninzi, okanye uya kusebenza nzima kwaye ubambe ukufa.

Ukufumana umceli mngeni wako. Udinga ukuhambelana kwiipropati zoomatshini kunye nokuchaneka kwe-dimensional. Asiyonto yokuthenga. Ndisebenze nababoneleli apho i-diameter yentonga yayiphantsi kokunyamezela, ukunciphisa indawo yoxinzelelo, okanye amandla okuqina ayesezantsi kakhulu kuluhlu lwebakala. Yingakho ukuba nomgca othe ngqo kumthombo wokuvelisa, kunokuba nje umthengisi, wongeza umaleko wokuthembeka. Umvelisi obekwe kwiqela elikhulu lemveliso efana neSithili saseYongnian, kunye nezibonelelo zayo zolungiselelo ezikufuphi noololiwe abakhulu kunye nothungelwano lweendlela, zihlala zithetha ulawulo olungcono lokubonelela. Ukujonga indawo efana https //wwww.ziitasteners.com ikunika ingqiqo yoluhlu lweemveliso zabo kunye nobungcali, esisisiqalo sokuvavanya isakhono sabo ngokuthe ngqo iintonga ezinemisonto iimfuno, ukusuka kwintsimbi yekhabhoni eqhelekileyo ukuya kumabakala engxubevange.

Ixesha lokukhokela ngomnye unobangela. Kwintonga eqhelekileyo ye-zinc-plated, mhlawumbi iveki. Ngobude obude, amandla aphezulu, intonga yegalvanized eshushu-dip enemisonto ethile, unokuba ujonge ukuqhuba imveliso. Ngalo lonke ixesha ucingela oku. Ndilibazise iiprojekthi ndilinde ukuba iintonga ezichanekileyo zifike, kuba ukubuyisela ibingelokhetho.

Umthetho olula woFakelo

Torque. Wonke umntu uthetha ngayo, bambalwa abayisebenzisa ngokuchanekileyo. I-torque efunekayo ukufezekisa umthwalo onikiweyo we-clamp iyahluka ngokungaqhelekanga kunye nokuthambisa. Intambo ye-lubricated (kunye ne-anti-seize okanye ioli) inokunciphisa i-torque efunekayo nge-30-40% xa kuthelekiswa nomtya owomileyo. Ukuba ulandela i-torque spec evela kwincwadana, khangela ukuba ithatha yomile okanye ifakwe i-lubricated. Ukusebenzisa i-torque eyomileyo kwintambo efakwe i-lubricated iyakwazi ukugqithisa ngokulula kwaye yolule intonga, ekhokelela ekungaphumeleli.

Ulungelelwaniso lubalulekile. Ukuba intonga iyagoba, umthamo wayo uyehla. Sebenzisa iiwasha ezingqukuva okanye ukulinganisa amandongomane ukuba umphezulu awuhambelani. Ndakhe ndaphanda ukusilela kwesakhiwo apho intonga ye-intshi ye-1-intshi yahlutha. Ikhefu libonise iimpawu zakudala zokudinwa. Unobangela? Umqadi owawuwuxhomile wawujike kancinane phantsi komthwalo, wabeka intonga kumjikelo wokugoba owawungazange uyilelwe. Ukulungiswa kwakuyiwasha yesitulo esilula esingqukuva, esixabisa iipeni xa kuthelekiswa nokulungiswa.

Musa ukulibala malunga nokukhuselwa kwe-corrosion kwindibano efakiweyo. Intonga isenokuba ayinabala, kodwa kuthekani ngamandongomane neewasha? Izinyithi ezingafaniyo zibangela ukubola kwegalvanic. Kwimekobume efumileyo, ukusebenzisa i-carbon steel nut kwintonga engenastainless inokutya indongomane ngokukhawuleza ngokumangalisayo. Tshatisa izixhobo okanye usebenzise iipads zokugquma.

Xa Izinto zingahambi kakuhle: Uhlalutyo lokungaphumeleli

Ayiphumelelanga iintonga ezinemisonto balisa ibali. I-brittle, i-crystalline fracture surface ngokuqhelekileyo ibonisa i-overload okanye i-hydrogen embrittlement (eqhelekileyo kunye ne-electroplated high-strength steel). Ukwaphuka okugudileyo, amakhonkco agxininisiweyo akhokelela kumlebe wokugqibela wokucheba kukungaphumeleli kokudinwa okuqhelekileyo - umthwalo wawuhamba ngebhayisekile. Intonga eyoluliweyo, enentamo phambi kokuba ukungaphumeleli kubhekiselele kwi-ductile overload. Ukufunda le miqondiso kukunceda ukulungisa unobangela, hayi nje indawo indawo.

Enye yeentsilelo zethu ezifundisayo yayikwisikrini esingcangcazelayo. Iinduku zaqhubeka zikhulula kwaye emva koko zidinwa. Iiwasha zokutshixa, i-threadlocker - akukho nto yasebenza ixesha elide. Isisombululo sasingeyontonga engcono; ibikukutshintsha uyilo ukusebenzisa udibaniso olugxininisiweyo kunye ne-torque nut ekhoyo, ukuhambisa indawo yokudinwa kwindawo enokuthathelwa indawo ngokulula ngakumbi. Ngamanye amaxesha, impendulo echanekileyo kukulungisa uxhulumaniso, kungekhona ukugcina ubungakanani bentonga.

Iyaphela koku: phatha iintonga ezinemisonto njengezixhobo zobunjineli, hayi ihardware yegeneric. Cacisa imathiriyeli, ibakala, ukutyabeka, kunye nodidi lomsonto ngononophelo olukhulu njengoko ubuya kwenza impompo okanye ivalve. Qonda imeko yomthwalo - static, dynamic, corrosive. Kwaye zivela kumntu owuqondayo umahluko, umntu ofakwe kwinkqubo yokuvelisa, hayi ikhathalogu. Loo ngqalelo kwiinkcukacha yinto eyahlula ukufakela okuqinileyo kwintloko yesondlo yexesha elizayo.
