Iintlobo zeeLinings zePipeline ezilinganiswa yi-Electromagnetic Flowmeters

1. Iingubo zerabha

1.1 Irabha yendalo

Irabha yendalo lukhetho oludumileyo kwiilinki zemibhobho xa kusetyenzwa apho i-medium elinganisiweyo ingangcolisi kwaye inobushushu obuphantsi. Inika ukumelana okuhle kokurhawuzelelwa, okwenza ukuba ifaneleke kulwelo olunokuba namasuntswana axhonyiweyo, njengeentlobo ezithile zamanzi amdaka okanye amadaka anezimbiwa ezithambileyo. Umzekelo, kwisityalo sokucoca amanzi amdaka, iinkqubo zonyango oluphambili zihlala ziquka ukuhamba kwamanzi amdaka aneenkunkuma ezahlukeneyo. Imibhobho yendalo enerabha inokumelana ngempumelelo nokungqubana okubangelwa zezi suntswana ngelixa ihambelana nei-flowmeter ye-electromagnetic.Ingaphakathi lerabha yendalo libonelela ngomphezulu ogudileyo wangaphakathi, linciphisa ukumelana nokuhamba kwamanzi kwaye liqinisekisa ukulinganiswa ngokuchanekileyo kokuhamba kwamanzi nge-electromagnetic flowmeter.

1.2 Irabha yokwenziwa (umz., iNeoprene)

Iirabha ezenziweyo ezifana ne-neoprene zinokumelana okuphezulu kweekhemikhali xa kuthelekiswa nerabha yendalo. Iipayipi ezifakwe i-Neoprene zifanelekile ukulinganisa ulwelo olune-corrosive kancinci, njengee-asidi ezithile ezibuthathaka okanye ii-alkalis ngaphakathi koluhlu oluthile loxinzelelo. Kwiinkqubo zoshishino apho kukho ii-arhente zokucoca iikhemikhali ezithuthwa ngemibhobho, iipayipi ezifakwe i-neoprene zingasetyenziswa kunyeii-flowmeters ze-electromagnetic.I-neoprene lining ayikhuseli nje kuphela umbhobho ekuhlaselweni ziikhemikhali kodwa ikwagcina ukuthembeka kwentsimi ye-electromagnetic esetyenziselwa ukulinganisa ukuhamba kwamanzi, okuvumela ukumisela ngokuchanekileyo izinga lokuhamba kwamanzi kwezi khemikhali zisabelayo.

2. Iilineni zeFluoropolymer

2.1 I-PTFE (i-Polytetrafluoroethylene)

I-PTFE yaziwa ngokuxhathisa kwayo iikhemikhali ngendlela ebalaseleyo, ikwazi ukumelana neekhemikhali ezininzi ezibola kakhulu, kuquka ii-asidi ezinamandla, iziseko, kunye nee-oxidizing agents. Iipayipi ezifakwe kwi-PTFE zisetyenziswa kakhulu kushishino lweekhemikhali, ukwenziwa kwamayeza, kunye nemveliso ye-semiconductor. Kwisityalo seekhemikhali apho iikhemikhali ezirhabaxa ezifana ne-sulfuric acid egxininisiweyo okanye i-hydrofluoric acid zidluliselwa khona, i-electromagnetic flowmeter ingafakwa kwipayipi efakwe kwi-PTFE. I-PTFE lining iqinisekisa ukuba ipayipi ayonakaliswa yi-corrosive medium, kwaye iipropati zayo ezingahambisi mafutha nezizinzileyo kwiikhemikhali aziphazamisi umgaqo wokulinganisa i-electromagnetic. Oku kuvumela ukulinganiswa kokuhamba ngokuchanekileyo nakwiindawo ezinobungozi kakhulu zeekhemikhali.

2.2 I-FEP (i-Fluorinated Ethylene Propylene)

I-FEP yenye into eyenziwe nge-fluoropolymer lining material. Inokumelana okufanayo kweekhemikhali kwi-PTFE kodwa ineenzuzo ezithile ngokubhekiselele ekuqhubekekeni nasekukhanyeni. Iipayipi ezinemigca ye-FEP zihlala zisetyenziswa kwiindawo apho kufuneka ukuhlolwa okubonakalayo kokuhamba kolwelo ukongeza ekulinganisweni okuchanekileyo kokuhamba. Umzekelo, kwezinye ii-chemical reactions zelabhoratri okanye ekuvelisweni kolwelo olucocekileyo kakhulu kwishishini lezemithi, iipayipi ezinemigca ye-FEP zinokudityaniswaii-flowmeters ze-electromagneticUkucaca kwe-FEP kwenza abaqhubi bakwazi ukubona imeko yokuhamba kolwelo, ngelixa i-electromagnetic flowmeter inika idatha echanekileyo yesantya sokuhamba kolwelo.

3. Iingubo zobumba

Iipayipi ezenziwe ngeseramikhi zilungele kakhulu usetyenziso olufuna ukumelana nobushushu obuphezulu kunye nokumelana nokuguguleka okuhle. Iiseramikhi zinendawo yokunyibilika ephezulu kwaye zinokugcina iipropati zazo zoomatshini kunye neekhemikhali kubushushu obuphezulu. Kwimizi-mveliso efana nokuveliswa kombane, apho kukho iigesi ezishushu eziqulethe umlotha okanye amadaka obushushu obuphezulu, iipayipi ezenziwe ngeseramikhi zingasetyenziswa kunye nee-electromagnetic flowmeters. I-ceramic lining ikhusela umbhobho kwimpembelelo yokukhukuliseka kwamasuntswana esantya esiphezulu kulwelo, kwaye i-electromagnetic flowmeter inokulinganisa ngokuchanekileyo isantya sokuhamba kwezi fluids zobushushu obuphezulu. Nangona iiseramikhi zizinto ezibuthathaka, ukufakelwa ngokufanelekileyo kunye noyilo lwenkqubo yepayipi kunokuqinisekisa ukusebenza kwazo okuthembekileyo kwexesha elide kunye nee-electromagnetic flowmeters.

Ukuququmbela,ii-flowmeters ze-electromagneticingasetyenziswa ngempumelelo kwiipayipi ezifakwe irabha (zombini zendalo nezenziweyo), iifluoropolymers (PTFE kunye neFEP), kunye neeseramikhi. Ukukhethwa kwezinto zokufaka ulwelo kuxhomekeke kwiimpawu ezithile zesixhobo esilinganisiweyo, njengokwakheka kwamakhemikhali, ubushushu, kunye nokurhawuzelelwa, ukuqinisekisa ukulinganiswa kokuhamba kwamanzi ngokuchanekileyo nangokuthembekileyo.
