Ukongeza ekuqinisekiseni ukwakheka kweekhemikhali kunye neempawu zoomatshini, uvavanyo lwe-hydrostatic lwenziwa nganye nganye, kwaye uvavanyo lokutshaya kunye nolwe-flashing lwenziwa. Ukongeza, kukho iimfuno ezithile zesakhiwo esincinci, ubungakanani beenkozo, kunye nomaleko wokususa iikhabhoni kumbhobho wentsimbi ogqityiweyo.
Uvavanyo lokuThatha:
1. Kwizinto zentsimbi zemveliso, umenzi kufuneka enze uvavanyo lokutsalwa. Kwipayipi edityanisiweyo yombane, exhomekeke kukhetho lomenzi, uvavanyo lokutsalwa lunokwenziwa kwipleyiti yentsimbi eyayisenza ipayipi okanye ipeyintwe ngqo kwipayipi yentsimbi. Uvavanyo olwenziwe kwimveliso lungasetyenziswa njengovavanyo lwemveliso.
2. Iityhubhu zovavanyo mazikhethwe ngokungacwangciswanga. Xa kufuneka uvavanyo oluninzi, indlela yokuvavanya kufuneka iqinisekise ukuba iisampulu ezithathiweyo zingamela ukuqala nokuphela komjikelo wonyango lobushushu (ukuba kuyasebenza) kunye neziphelo zombini zetyhubhu. Xa kufuneka uvavanyo oluninzi, ipateni mayithathwe kwiityhubhu ezahlukeneyo ngaphandle kokuba isampulu yetyhubhu etyebileyo ingathathwa kuzo zombini iziphelo zetyhubhu.
3. Isampulu yombhobho engenamthungo ingathathwa nakweyiphi na indawo kumjikelezo wombhobho; isampulu yombhobho ene-weld kufuneka ithathwe malunga nama-90 ° ukuya kumthungo we-weld, okanye ngokukhetha komenzi. Iisampulu zithathwa malunga nekota yobubanzi bomcu.
4. Nokuba ngaphambi nasemva kovavanyo, ukuba ukulungiswa kwesampuli kufunyaniswe kunesiphene okanye kukho ukunqongophala kwezinto ezingabalulekanga kwinjongo yovavanyo, isampuli ingasuswa ize ithathelwe indawo yenye isampuli eyenziwe ngetyhubhu efanayo.
5. Ukuba uvavanyo lokuxinana olumele iqela leemveliso aluhlangabezani neemfuno, umenzi angathabatha ezinye iityhubhu ezi-3 kwiqela elifanayo leetyhubhu ukuze zihlolwe kwakhona.
Ukuba zonke iimvavanyo eziphindwe kabini zeesampuli ziyahlangabezana neemfuno, ibhetshi yeetyhubhu iyafaneleka ngaphandle kwetyhubhu engafanelekanga eyayithathelwe isampuli ekuqaleni.
Ukuba iisampulu ezingaphezulu kwesinye zithathwe isampulu ekuqaleni okanye iisampulu enye okanye ezingaphezulu zokuvavanywa kwakhona azihlangabezani neemfuno ezichaziweyo, umenzi unokuhlola iqela leetyhubhu nganye nganye.
Ibhetshi yeemveliso ezingafunwayo zinokufudunyezwa kwaye ziphinde zicutshungulwe njengebhetshi entsha.
Uvavanyo lokuTyatya:
1. Isampuli yovavanyo mayibe yiringi yovavanyo okanye isiqwenga sokugqibela esingaphantsi kwe-63.5mm (2-1 / 2in).
2. Iisampuli zinganqunyulwa ngaphambi kokuba kulungiswe ubushushu, kodwa zisetyenziswe kubushushu obufanayo nobo buboniswe ngumbhobho. Ukuba kusetyenziswa uvavanyo lwebhetshi, kuya kuthathwa amanyathelo okuchonga ubudlelwane phakathi kwesampuli kunye nombhobho wokuthatha isampuli. Isithando ngasinye kwibhetshi nganye kufuneka sityunyuzwe.
3. Isampuli mayibe tyaba phakathi kweepleyiti ezimbini ezilinganayo. Kwiseti nganye yeesampuli zovavanyo lokutyibiliza, enye i-weld ibekwe tyaba kwi-90 ° kwaye enye ibekwe tyaba kwi-0 °. Isampuli mayibe tyaba ide iindonga zetyhubhu ziqhagamshelane. Ngaphambi kokuba umgama phakathi kweepleyiti ezilinganayo ube ngaphantsi kwexabiso elichaziweyo, akukho mifantu okanye amaqhekeza afanele avele nakweyiphi na inxalenye yepateni. Ngexesha lonke lenkqubo yokutyibiliza, akufuneki kubekho isakhiwo esibi, ii-welds ezingadibaniyo, i-delamination, i-metal overburn, okanye i-metal extrusion.
4. Nokuba ngaphambi nasemva kovavanyo, ukuba ukulungiswa kwesampuli kufunyaniswe kunesiphene okanye kukho ukunqongophala kwezinto ezingabalulekanga kwinjongo yovavanyo, isampuli ingasuswa ize ithathelwe indawo yenye isampuli eyenziwe ngetyhubhu efanayo.
5. Ukuba nayiphi na isampuli emele ityhubhu ayihlangabezani neemfuno ezichaziweyo, umenzi angathatha isampuli kwisiphelo esifanayo setyhubhu ukuze avavanyelwe okongezelelweyo de kuhlangatyezwane neemfuno. Nangona kunjalo, ubude bombhobho ogqityiweyo emva kokuthatha isampuli akufuneki bube ngaphantsi kwe-80% yobude bokuqala. Ukuba nayiphi na isampuli yombhobho emele iqela leemveliso ayihlangabezani neemfuno ezichaziweyo, umenzi angathatha iityhubhu ezimbini ezongezelelweyo kwiqela leemveliso aze asike iisampuli ukuze zivavanywe kwakhona. Ukuba iziphumo zolu vavanyo lokuphinda zihlangabeze zonke iimfuno, iqela leetyhubhu liyafaneleka ngaphandle kombhobho owawukhethwe ekuqaleni njengesampuli. Ukuba nayiphi na isampuli yokuphinda ivavanywe ayihlangabezani neemfuno ezichaziweyo, umenzi angathatha ityhubhu ezisele zeqela nganye nganye. Ngokhetho lomenzi, naliphi na iqela leetyhubhu linokulungiswa ngokutsha kwaye livavanywe kwakhona njengeqela elitsha leetyhubhu.
Uvavanyo lweMpembelelo:
1. Kwiityhubhu, iseti yeesampuli kufuneka ithathwe kwilothi nganye (ngaphandle kokuba iinkqubo ezibhaliweyo zibonisiwe ukuba ziyahlangabezana neemfuno zomthetho). Ukuba umyalelo umiselwe kwi-A10 (SR16), uvavanyo luyimfuneko.
2. Kwisingxobo, kufuneka kuthathwe imibhobho yentsimbi emithathu kwibhetshi nganye ukuze kwenziwe uvavanyo. Iityhubhu zovavanyo mazikhethwe ngokungacwangciswanga, kwaye indlela yokuthatha isampuli kufuneka iqinisekise ukuba iisampulu ezinikiweyo zinokumela ukuqala nokuphela komjikelo wonyango lobushushu kunye neziphelo zangaphambili nangasemva zesingxobo ngexesha lonyango lobushushu.
3. Uvavanyo lweCharpy V-notch impact
4. Nokuba ngaphambi nasemva kovavanyo, ukuba ukulungiswa kwesampuli kufunyaniswe ukuba kuneziphene okanye kukho ukunqongophala kwezinto ezingabalulekanga kwinjongo yovavanyo, isampuli inokulahlwa ize ithathelwe indawo yenye isampuli eyenziwe kwityhubhu efanayo. Iisampuli akufuneki zigwetywe njengezineziphene kuba nje zingahlangabezani neemfuno zamandla afunxwayo.
5. Ukuba iziphumo zeesampuli ezingaphezu kwesinye zingaphantsi kuneemfuno zamandla afunxwayo ezincinci, okanye iziphumo zesampuli enye zingaphantsi kwe-2/3 yeemfuno zamandla afunxwayo ezincinci ezichaziweyo, kufuneka kuthathwe iisampuli ezintathu ezongezelelweyo kwisiqwenga esinye kwaye zivavanyelwe kwakhona. Amandla empembelelo yesampuli nganye evavanyiweyo kwakhona aya kuba makhulu okanye alingane nemfuneko yamandla afunxwayo encinci echaziweyo.
6. Ukuba iziphumo zovavanyo oluthile azihlangabezani neemfuno kwaye imiqathango yovavanyo olutsha ayihlangabezani, kuthathwa iisampulu ezintathu ezongezelelweyo kwinxalenye nganye kwezithathu zebhetshi. Ukuba zonke iimeko ezongezelelweyo ziyahlangabezana neemfuno, ibhetshi iyafaneleka ngaphandle kweyokuqala engaphumelelanga. Ukuba iziqwenga zovavanyo ezingaphezulu kwesinye azihlangabezani neemfuno, umenzi unokukhetha ukuhlola iziqwenga eziseleyo zebhetshi nganye nganye, okanye aphinde ayifudumeze ibhetshi aze ayihlole kwibhetshi entsha.
7. Ukuba ngaphezu kwesinye sezinto ezintathu zokuqala ezifunekayo ukubonisa uluhlu lweemfaneleko ziyaliwa, ukuphinda kuhlolwe akuvumelekanga ukubonisa ukuba uluhlu lweetyhubhu lufanelekile. Umenzi unokukhetha ukuhlola uluhlu oluseleyo ngokulandelelana, okanye ukuphinda kufudumale uluhlu aze aluhlole ngokulandelelana.
Uvavanyo lwe-Hydrostatic:
1. Umbhobho ngamnye kufuneka uvavanywe uxinzelelo lwe-hydrostatic lombhobho wonke emva kokuba ujiyile (ukuba kufanelekile) kunye nonyango lokugqibela lobushushu (ukuba kufanelekile), kwaye kufuneka ufikelele kuxinzelelo lwe-hydrostatic oluchaziweyo ngaphandle kokuvuza. Ixesha lokubamba uxinzelelo lovavanyo lenziwe ngaphantsi kwe-5s. Kwimibhobho edibeneyo, ii-welds zemibhobho kufuneka zihlolwe ukuvuza phantsi koxinzelelo lovavanyo. Ngaphandle kokuba uvavanyo lonke lombhobho lwenziwe ubuncinane kwangaphambili kuxinzelelo olufunekayo kwimeko yokugqibela yombhobho, umzi-mveliso wokucubungula intambo kufuneka wenze uvavanyo lwe-hydrostatic (okanye ulungiselele uvavanyo olunjalo) kumbhobho wonke.
2. Imibhobho eza kunyangwa ngobushushu iya kuvavanywa nge-hydrostatic emva konyango lokugqibela lobushushu. Uxinzelelo lovavanyo lwazo zonke imibhobho ezineziphelo ezinemisonto kufuneka ubuncinane lube luxinzelelo lovavanyo lwemisonto kunye nee-couplings.
3. Emva kokuba kusetyenzwe ngobukhulu bombhobho ogqityiweyo osicaba kunye nazo naziphi na iindawo ezimfutshane eziphathwe ngobushushu, uvavanyo lwe-hydrostatic kufuneka lwenziwe emva kokuphela okusicaba okanye umsonto.
