Isinciphisi-sibambe esinye

Yintoni i-single-press reducer?

I-Shenchi's high-effective single-press reducer ifakela umbhobho obhityileyo osetyenziselwa ukudityaniswa kwedayamitha yokunciphisa umbhobho. Iziphelo zayo ezimbini zineemitha ezahlukeneyo kwaye zixhunywe ngokusebenzisa iteknoloji yokushicilela enye. Ngethuba lofakelo, iipayipi zenkcazo ehlukeneyo zifakwe kwiisokethi kuzo zombini iziphelo, kwaye isixhobo esikhethekileyo sokucinezela sisetyenziselwa ukusebenzisa ukunyanzeliswa kwe-radial. Oku kubangela ukuguqulwa kweplastiki phakathi kokufakwa kunye nombhobho, ukudala i-360 ° circumferential clamping force. Ngaxeshanye, i-EPDM eyakhelwe-ngaphakathi ikhonkco yokutywina ixinzelelwe ukufezekisa i-elastic seal. Yonke inkqubo ayifuni i-welding okanye i-threading kwaye igqitywe ngemizuzwana. Imveliso yenziwe ngobhedu olukhethiweyo, i-SUS304, kunye ne-SUS316L yezixhobo, enikezela ukuxhathisa okugqwesileyo kwaye isetyenziselwa ngokubanzi ukudibanisa inguqu egudileyo phakathi kwemibhobho engundoqo kunye nesebe kunikezelo lwamanzi, i-drain, igesi, kunye neenkqubo ze-HVAC.

Iiparamitha zeMveliso

Ukungahambelani kwezinto kwenza ukuba umhlwa ube nzima ukuwuphepha.

Ukuba i-pitting okanye i-rust ivela kwi-Shenchi manual hydraulic single-clamp 90-degree elbows, isizathu esiphambili kukungahambelani phakathi kokukhethwa kwezinto eziphathekayo kunye nendawo yokusebenza. I-SUS304 insimbi engenasici ithanda ukuba ne-chloride ion pitting corrosion kwindawo ene-ion concentrations ye-chloride ephezulu (efana neendawo eziselunxwemeni, amanzi olwandle, amadama okuqubha, kunye nezityalo zekhemikhali), ebonakala njengemingxuma efana nepinhole kumphezulu. I-SUS316L, nangona kunjalo, iqulethe i-molybdenum, iphakamisa kakhulu ukuchasana kwayo ne-chloride ion corrosion. Ukuba i-304 imathiriyeli isetyenziswe ngempazamo kwindawo enomhlwa kakhulu, ukubola komngxuma kunzima ukuwuphepha. Kucetyiswa ukuba kusetyenziswe izinto ezingama-316L kwiiprojekthi zonxweme okanye zeekhemikhali; ubhedu alufanelekanga kwi-asidi eyomeleleyo kunye neendawo ze-alkali.

I-passivation layer yonakaliswa, kwaye i-corrosion ithatha ithuba lokungena

Esinye isizathu se-rust kwi-single-clamp 90-degree elbows ephathwa ngamaxabiso akhethiweyo yi-Shenchi ngumonakalo kwi-surface passivation layer. Ukumelana nokubola kwentsimbi engatyiwayo kuxhomekeke kwifilimu exineneyo yechromium oxide passivation film kumphezulu wayo. Ukuba i-fitting ikrwelwe, ingqushiwe, iphantsi, okanye iphantsi kwe-welding spatter ngexesha lokucubungula, ukuthuthwa, okanye ukufakela, ifilimu ye-passivation iyonakala, kwaye i-substrate yesinyithi eveziweyo iya kuhlwa kwindawo efumileyo. Ukongeza, ukuba i-fitting ayikhange ifumane unyango olwaneleyo kunye ne-passivation ngaphambi kokuba ushiye umzi-mveliso, okanye ukuba umgangatho we-passivation uphantsi, uya kukhokelela ekunciphiseni ukuxhathisa ukubola kunye nokubonakala kwamabala e-rust ngexesha elifutshane.

Ukonakala kokusingqongileyo kunye nokubola kwesinyithi okungafaniyo kuyingozi.

Iingqiniba ze-90 ze-Shenchi ze-single-press, ezenziwe e-China, zijongene nomngcipheko okhulayo wokugqwala kwiindawo ezinoqhagamshelwano olude kunye neendaba ezitshabalalisayo okanye iimeko zetyuwa ephezulu. Ngexesha lokufaka i-press-fitting, ukuba i-burrs ayisuswanga ngokufanelekileyo ebusweni bokuphela kombhobho, inokuwela kumbhobho kwaye ikrwele ifilimu ye-passivation eludongeni lwangaphakathi. Ngaphezu koko, ukuba isinyithi esingafaniyo sidityaniswe kwinkqubo yokubhobhoza (umzekelo, izixhobo zetsimbi ezingenasici ngokudibana ngokuthe ngqo nobhedu okanye i-carbon steel pipes), i-electrochemical corrosion ingenzeka phantsi kweempembelelo ze-electrolytes, ngokukhethekileyo i-corroding i-stainless steel fittings. Ukuqhagamshelana ngokuthe ngqo phakathi kweentsimbi ezingafaniyo kufuneka kuphetshwe; iigaskets ezikhuselayo kufuneka zisetyenziswe ukuba zodwa.

Uthintelo lungundoqo, kwaye ukhetho lwemathiriyeli lubalulekile. 

Kwi-Shenchi manual hydraulic single-press 90-degree elbows, iindawo ezincinci ze-rust zingasuswa nge-stainless steel cleaner okanye isisombululo se-citric acid, evumela ukuba ifilimu ye-passivation iguqulwe. Ukugqobhoza okukhulu okanye ukugqobhoza kufuna ukuba kufakwe endaweni yoko kufakelwe. Amanyathelo okuthintela aquka: ukukhetha izixhobo ezifanelekileyo ezisekelwe kokusingqongileyo (316L kwiindawo eziselunxwemeni); ukuphepha imikrwelo yomhlaba ngexesha lofakelo; ukususa ngokucokisekileyo i-burrs kumbhobho ngaphambi kokucinezela; ukuphepha ukudibana ngokuthe ngqo phakathi kweentsimbi ezifanayo; kunye nokucoca rhoqo umphezulu wokulinganisa. I-Shenchi isekela i-ODM / i-OEM ngokwezifiso kwaye inokucebisa izinto ezifanelekileyo ezisekelwe kwiimeko zokusebenza. Ukuze ufumane isaphulelo sekowuti kwi-single-press 90-degree elbows, nceda uqhagamshelane nathi.
