Ungayilungisa njani ibhobho kumbhobho? Iintlobo zemibhobho, izixhobo zokuhambisa

Isidingo sokwenza uxhulumaniso phakathi kweendlela zobunjineli zombhobho kwenzeka xa zombini i-gasket yokuqala kwaye ngexesha lokwenziwa komsebenzi kwenziwa. Isici sokumakhanjiswa kwemibhobho kwiinkqubo zonxibelelwano kukubonelelwa ngokusemthethweni kokuqina. Kwiimeko ezithile ezingaqhelekanga, le nto ayikho nto ekhethekileyo, kwaye iyakunyankelwa. Ukukhangela impendulo kumbuzo wokukrazula ibhobho kumbhobho, umntu akakwazi ukwenza ngaphandle kwengcaciso yezobuchwepheshe zanamhlanje. Okokuqala, oku kusebenza kwimpahla yeplastiki, engazange ifikeleleke kwiimarike kungekude kudlulileyo kwaye yaqalisa ngokukhawuleza indlela entsha yokwenza i-soldering kumsebenzi wendibano. Kodwa kunye nemibhobho yemveli yensimbi idibeneyo kwizinga langoku kunye nezobuchwepheshe, kunokuba iminyaka engama-10-15 edlulileyo.

Ziziphi iintlobo zeemibhobho ezinokuphengulwa?

Uluhlu olupheleleyo lwemibhobho elisetyenziselwa kumanzi, i-gesi kunye neendlela zokufudumala zingahlulwa zibe zimbini iintlobo zezinto: izinto zetsimbi kunye neeplastiki. Kuzo zombini iimeko, iipayipi zingasuswa, kungenjalo ukusebenza kunye nokufakela nabo kungenakwenzeka. Ewe, njengenye indlela, sinokukhumbula indlela yoxhumo lwefayile, esetyenziselwa ukusetyenziswa kwiinkqubo zetsimbi eziyinkimbinkimbi, kodwa le nkqubo isele ingasebenzi kwaye ingasetyenziswanga. Namhlanje, iipayipi zensimbi zidibaniswa ngeendlela zombane ze-arc, ezenza kube lula ukunxibelelana. Itheknoloji yokusebenza ngamabhobho eplastiki ahluke. Kule meko, ingxaki yokusebenzisa i-welding ye-classic ingenxa yokuthambisa kunye ne-viscosity yesakhiwo. Ngoko ke, kusetyenziswe iindlela zokuqhaqhazela kunye nokudibanisa, ezibandakanyiweyo kwiqela elibanzi lobuchwepheshe be-welding. Ngexesha elifanayo, iindlela zobuchwepheshe zokuphumeza ezo ntlobo zonxibelelwano zihluke kakhulu kwizinto zokulondolozwa zendalo.

Izixhobo zokulondoloza

Isixhobo esithandwa kakhulu kwi- arc welding yamabhobho yensimbi yindlela ye-semiautomatic inverter. Kwinkqubo yokusebenza ukukhusela indawo yokusebenza evela kwimpembelelo yangaphandle, i-gesi ekhethekileyo isetyenziswe, evumela ukuba kufinyelele kwizinga eliphezulu lokuchaneka nokuqina kwintambo. Ukuthandwa koomatshini bokunyusa i- arc ye-arc ye- MMA kuyahla. Le ndlela yindlela elula kwaye elula yokufumana umthumo ngokuhamba ngokubanzi kwezixhobo, kodwa kunemingcipheko ebalulekileyo, phakathi kweyiphi imveliso ephantsi kunye nokubunjwa kwe-slag ebusweni bomthungo omele ususwe. Ngokubhekiselele kwindlela yokwenza iimpahla zeplastiki, izinto eziqhelekileyo zisetyenziselwa ukunyanzelisa iingxube ze-soldering. Ezi zombini iipropropylene zamabhobho kunye nee-PVC zelungelelaniswa kumatshini onobuso, ukukhangela, isitya sokusika (i-element element) kunye nesisombululo sokutywinwa kwiisakhiwo kwi-design.

Ukulungiselelwa kweemibhobho zensimbi zokuhambisa

Iibhobho zihlambulukile ngokucokisekileyo ukwenzela ukuba zenzeke ngakumbi. Amacandelo omabini amagosa kufuneka abe neqonga elisezantsi kwi-degree-45 degree degree relative to axis of bipe. Kule meko, i-butt esicacileyo ebanzi ubuncinane ubuncinane be-2 mm kufuneka ihlale. Nangona kunjalo, iiparamitha ezithile ziyakwazi ukuhluka kuye kuxhomekeke kwimida yeeripe. Akubalulekanga kumbuzo wendlela yokuhambisa ipayipi kumbhobho, ukulungelelaniswa okuchanekileyo. Ngokukhawuleza ngaphambi kokusebenza kubalulekile ukudibanisa - ukwenzela ukuba ukuchaneka ngokuthe ngqo ekunqumeni umgca wezinto ezimbini ezifakwe kwi-welded ziqinisekisiwe. Kwezinye iimeko, i-tack yenziwe, oko kukuthi, umxokezana omfutshane utyunjwa, okwenzeka ngethuba lwenkqubo yendibano njengesiqendu kwisakhiwo.

I-Electrowelding yamabhobho ensimbi

Okokuqala, "ukuphoqa" kufuneka kwenziwe. Ikhebula kufuneka likhutshwe kwaye lijoliswe kumnikazi othile. Ngomshini wokulumala, umlinganiselo ophezulu wamandla okwangoku ofunekayo kwizinto ezithile zibekwe - ixabiso eliqhelekileyo liyadingeka kwi-alloys ezithambileyo, kwaye amaxabiso aphezulu afanelekileyo ama-alloy alloy. Emva koko i-arc iyabhalwa, kwaye i-electrode ifakwa kwi-angle ye-degree-60 ehambelana nomsebenzi. Ukususela kulo mzuzwana, ngokuthinta i-arc yeendawo zokusebenza, ukuqaliswa kweemibhobho zensimbi ziqala, ezinokuthi zihambisane nokubunjwa kweentlanzi. I-electrode kufuneka ihambe ngokukhawuleza, kodwa ukuze kungabikho ukunamathela. Ukuba kukho ukulibaziseka kwindawo enye, kukho umngcipheko wee-deformation excessive. Gwema oku kuya kuvumela i-arc efanayo kwi-surface. Ngenxa yoko, umgca we-wavy eqinile kufuneka ifom.

Ukulungiselela iipayipi zeplastiki zokwelusa

Okokuqala, iipayipi zinqunywe kwisayizi ngokuhambelana nobude obufanelekileyo besakhiwo esicwangcisiweyo. Oko kukuthi, kuyinqweneleka ukuhlela inkqubo yokufakela ngokubanzi ngendlela enjengokulumala kwinqanaba lokugqibela. Oku akusoloko kunokwenzeka, kodwa ukuba kunokwenzeka, wonke umsebenzi wobugcisa kunye nombhobho kufuneka uqhutywe phambi kwemisebenzi yokwesekwa. Kwakhona, akuyi kuba nzima ukushiya isitotyana esincinci, ukwenzela ukuba inxalenye yemveliso ingeniswe ngokufanelekileyo. Emva koko, njengoko kwimeko yesalathisi yesinyithi, iipolyinylchloride kunye neepropropylene iipayipi zihlambulukile. Umsebenzi oyintloko kweli nqanaba kukufumana imiphetho ehlambulukileyo, ecocekileyo kunye ehlambulukileyo. Ukunyaniseka kwesigxina sexesha elizayo kuxhomekeke kumgangatho weemida zombhobho. Oku kuyinyani ngokukodwa kwimveliso yeplastiki, kuba kwisakhiwo esithambileyo i-burrs encinci kunye nezitenxo zibaluleke kakhulu kwinkqubo yokukhangela.

Ukudibanisa kweepayipi zeplastiki

Iindidi ezinkulu zokufakelwa kweeplayipi zeplastiki zihlala zifakelwe ukufakelwa okuthe ngqo kwaye zivumele ukuveliswa kwamalungu amanqanaba. Iinkqubo zenkqubo yokuncedisa enye yinto encinci. Kwiinjongo ezinjalo, iisetyenzisi zokusebenza zisetyenziselwa ukuba zisebenze kunye nezinto zokufudumala ngendlela yemiguphu. Ngaphambi komsebenzi kubalulekile ukufaka ifowuni kwiplati ephezulu, kunye nokuseta umgangatho ophezulu wokushisa. Ngokomzekelo, ukunyuka kweempayipi zePVC kudla ngo-260 ° C. Kwimizuzu eyi-10-15. Emva kokutshintsha kwisixhobo kuya kufumana ulawulo oluphezulu lokushisa, kuya kwenzeka ukuba uqale ukusebenza.

Kwimicu yombhobho ifakwe imisebenzi yokuxhumano-kumlenze wokulungisa ukulungeleka, kwaye kwi-sleeve ifakwe ipayipi. Ukusebenza ngokwawo kuthatha imizuzu emininzi, njengoko iplastiki iyancibilika ngokukhawuleza. Ngoko ke, emva kokuba ifowuni ivuliwe, lungiselela ukugqiba inkqubo. Ukunyuka ngokuthe ngqo kweepayipi zePVC kunye noqhagamshelwano olulandelayo lwenziwa okokuqala ngenyathelo elinye. Isibambiso esibangelwayo kwimigqa yokuqala asikwazi ukujika kwaye uzame ukulungiswa, kuba kukho nayiphi na utshintsho emva kokususa izakuphazamisa amandla okona.

Kuthatha ixesha elingakanani ukupholisa loo nto?

Kwimeko yepayipi zensimbi, inkqubo ithatha ixesha elide kwaye, ngokusemthethweni, ukubunjwa kwebambisene kwenzelwe uluhlu lwesiseko. Ngako oko, isakhiwo sifumana amandla esele sele esetyenziswa kwiziganeko zokusebenza. Emva komsebenzi, kunelungelo lokulinda kude kube lula indawo yokuqhawula. Kuthatha imizuzu embalwa ukuba ulinde, ukuba i-welding idibene yamapayipi eplastiki. Ngokuxhomekeke kubukhulu beemveliso kunye nobunzulu bokuluthwa, le meko inokuhluka ukusuka kumithathu ukuya kwi-20 imizuzu. Kubalulekile ukuba uqaphele ukuba kumsebenzi ngesinyithi, kwaye ngexesha lokubambelela kwezinto zeplastiki, akunakwenzeka ukusebenzisa kuthetha ukukhawuleza inkqubo yokupholisa.

Ungayifaka njani ibhobho kumbhobho kumacandelo ahlukeneyo?

Ngamanye amaxesha ngenxa yezizathu ezithile, kubangelwa ukusetyenziswa komgangatho ongeyonto efanelekileyo, umntu kufuneka ahlangabezane namacandelo ahlukeneyo. Umzekelo, kunokubakho isidingo sokujoyina ipayipi yecetyhula kunye nomsebenzi owenziwe nge-cross section section. Kule meko, i-angle idibene nombhobho oqhelekileyo, apho ububanzi beshefu buhambelana nomda wesangqa. Ukusebenza kwenziwa kuphela kwirefu enye. Ngaphezulu, iteknoloji yamabhobho e-welding kunye namacandelwana ahlukeneyo anikezela ukutshaya kwe-arc kwizinto ezikhudlwana. Ngokukwabiwa ngokutsha kwensimbi yensimbi, kubalulekile ukwenza intsebenziswano phezu kwendawo yonke edibeneyo - kubonakala ukuba kulo mzekelo kuya kuba mkhulu kune-welding standard.

Isiphelo

Ubuchwephesha obutsha buye benza ukuba kube lula ukwenza iinkqubo zokuhambisa izinto ezahlukeneyo, ukwandisa kakhulu amathuba okufakela. Namhlanje, ngemibuzo malunga nokuba ungayilungisa njani ibhobho kumbhobho, akukho nakwezobuchule bezobugcisa. Ukunyuka kwe-Arc, umzekelo, kukuvumela ukuba usebenze nazo zonke izinto ezisetyenzisiweyo kuphela kwikhaya, kodwa nakwizoqoqosho zoshishino. Akukho mingcipheko yokufakela iipayipi zeplastiki, ezidibaniswa ngokulula kunye nezixhobo zokusebenza.
