I. Iingenelo eziphambili

1. Ufakelo Olulula Nolusebenzayo, Lulungele Iimeko Ezixineneyo

   Akukho mfuneko yokulungisa iflange enzima. Ufakelo lunokugqitywa ngokulufaka nje kwaye lubotshelelwe kwi-interface egciniweyo yepayipi, enokuqhutywa ngumntu omnye, okonga kakhulu ixesha lokwakha. Ifanelekile ngokukodwa kwiindawo ezimxinwa, izixhobo ezixhonywe eludongeni, okanye ukufakelwa kwemibhobho, kwaye isetyenziswa rhoqo ngabathengi bamanye amazwe kwimigca emincinci yemveliso kunye nezixhobo zelebhu.

2. Ukusebenza kakuhle kokutywina, ukunciphisa iingozi zokuvuza

   Xa isetyenziswa kwizinto zokutywina ezifana neteyiphu yokutywina yentambo ye-PTFE kunye nee-gaskets, umphezulu woqhagamshelwano lonxibelelwano olunemisonto uhambelana kakuhle, nto leyo enokuthintela ngokufanelekileyo ukuvuza kolwelo oluqhubayo (umz., izisombululo ze-asidi-base, amanzi amdaka). Xa kuthelekiswa noqhagamshelo lweflange, uqhagamshelo olunemisonto lubonelela ngokusebenza okuzinzileyo kokuvala phantsi kweemeko zoxinzelelo oluphantsi, kwaye isiphumo sokutywina asichaphazeleki lula ngexesha lokulungiswa kokuqhaqha kunye nokudibanisa kwakhona.

3. Ukuchaneka Okuphezulu Kokulinganisa IiCaliber Ezincinci, Ukulahleka Koxinzelelo Oluphantsi

   Ii-threaded connection electromagnetic flowmeters zihlala zifumaneka kwii-calibers ukusuka kwi-DN10 ukuya kwi-DN50. Kule nkcazo, i-sensor inesakhiwo esincinci, esiqinisekisa intsimi yokuhamba kolwelo oluzinzileyo ngexesha lokujikeleza, nto leyo enciphisa i-eddy currents kunye ne-evenly flow velocity, ngaloo ndlela iphucula ukuchaneka kokulinganisa. Okwangoku, akukho ziprotrusions ezongezelelweyo (ezifana nee-flange bolts) eludongeni lwangaphakathi lombhobho, nto leyo ebangela ukuxhathisa kolwelo oluphantsi kunye nokulahlekelwa koxinzelelo, okwenza ukuba lufaneleke kwiimeko ezineemfuno zolawulo lokusetyenziswa kwamandla.

4. Iindleko ezilawulekayo, Ukuziqhelanisa nokuthenga okuncinci

   Umzimba wevalvu kunye neendawo ezidibanisayo zoqhagamshelo olunemisonto zinesakhiwo esilula, esineendleko zokuvelisa eziphantsi kunezoqhagamshelo lweflange, nto leyo eyenza ixabiso lemveliso likhuphisane ngakumbi. Ukongeza, ubungakanani beodolo encinci (MOQ) yee-flowmeters ze-electromagnetic ezinemisonto emincinci buhlala buphantsi, nto leyo ehlangabezana neemfuno zeodolo yovavanyo lwabathengi abancinci baphesheya kwaye iba yimodeli ethandwayo yokukhuthazwa korhwebo lwangaphandle kwinqanaba lokuqala.

II. Imida yoSetyenziso

1. Ithintelwe yiCaliber kunye noxinzelelo, hayi kwiimeko ezihamba kakhulu kunye noxinzelelo oluphezulu

   Ngenxa yokunqongophala kwamandla omsonto kunye nokusebenza kokutywina, ubukhulu becala bee-flowmeters ze-electromagnetic ezinee-threaded connections abudluli kwi-DN50, kwaye uxinzelelo olusebenzayo luphakathi kwe-PN1.6 - PN4.0MPa. Ayinakwanelisa iimfuno zemibhobho emikhulu yobukhulu bemizi-mveliso (umz., ngaphezulu kwe-DN100) kunye nemibhobho yoxinzelelo oluphezulu (umz., iindawo zokuphuma zee-reactors zekhemikhali ezixineneyo eliphezulu), ngoko ke kucetyiswa ukuba kuqhagamshelwe ii-flange okanye ii-clamp-on endaweni yoko.

2. Imfuneko Ephezulu Yokuba Ne-Coaxiality Yepayipi Ngexesha Lokufakwa

   Ukuba umbhobho awuqhelekanga okanye ujongano olunemisonto lugobile ngexesha lokubopha izikrufu, oku kunokubangela amandla angalinganiyo kwisensor, nto leyo engachaphazeli nje kuphela ukuchaneka kokulinganisa kodwa inokwenzakalisa ujongano olunemisonto. Ngexesha lokufakelwa, kufuneka kuqinisekiswe ukuba amacandelo aneleyo ombhobho othe tye ongaphezulu (10D) kunye nomgca ongezantsi (5D), kwaye isensor kufuneka igcinwe kude nemithombo yokungcangcazela efana neempompo kunye neevalvu.

3. Ukugcinwa kunye nokuQhawulwa kuNciphiswe yiNdawo

   Ukuba inxalenye yoqhagamshelo olunemisonto iyagqwala okanye iyanamathela emva kokusetyenziswa ixesha elide, kufuneka izixhobo ezikhethekileyo zokuqhaqha, nto leyo enzima ukuyisebenzisa kwimibhobho eneendawo ezimxinwa. Xa kuthelekiswa nokuqhaqha kwebholiti yoqhagamshelo lweflange, uqhagamshelo olunemisonto alunakuguquguquka kokugcinwa, ingakumbi kwimidiya enoburhabaxa obunamandla, apho imeko yomsonto kufuneka ihlolwe rhoqo.

III. Amanqaku abalulekileyo ongezelelweyo oLungiso loRhwebo lwaNgaphandle

1. Uhlengahlengiso lwezinto ezisetyenziswayo kwiimeko zomsebenzi zamazwe ngamazwe

   Izinto ezikwi-interface enemisonto zinokwenziwa ngokwezifiso ngokwemigangatho yomthengi ephakathi neyengingqi. Izinto eziqhelekileyo ezimelana nokugqwala ezifana nentsimbi engagqwaliyo engama-316L kunye neHastelloy zamkelwe ukuhlangabezana neemfuno zezinto ezifunekayo kubathengi baseYurophu naseMelika kumashishini eekhemikhali nokutya. Kwiimeko ezinomgangatho ophezulu wamanzi, ii-interfaces ezinemisonto yentsimbi yekhabhoni nazo zinokubonelelwa ukulawula iindleko.

2. Ukuthobela iMigangatho yeMisonto yaMazwe ngaMazwe

   Imigangatho yemisonto iyahluka kwiindawo ezahlukeneyo zaphesheya, ngoko ke kuyimfuneko ukuqinisekisa iimfuno zabathengi kwangaphambili: Abathengi baseYurophu badla ngokusebenzisa i-BSPP (iBritish Standard Pipe Parallel), ngelixa abathengi baseMntla Melika bekhetha i-NPT (iNational Pipe Taper). Imigangatho efanelekileyo kufuneka iphawulwe ngokucacileyo kwincwadi yemiyalelo yemveliso ukuze kuthintelwe iingxaki zokuhambelana nokufakwa.
