Izinhlobo Zezingqimba Zamapayipi Ezilinganiswa Ngama-Electromagnetic Flowmeters

1. Ama-lining enjoloba

1.1 Irabha Yemvelo

Irabha yemvelo iyindlela ethandwayo yokufakwa kwamapayipi lapho i-medium elinganisiwe ingagqwali futhi inokushisa okuphansi. Inikeza ukumelana okuhle kakhulu kokuguguleka, okwenza ifanele uketshezi olungase luqukathe izinhlayiya ezilengayo, njengezinhlobo ezithile zamanzi amdaka noma ama-slurries anezinhlayiya ezithambile. Isibonelo, esitshalweni sokwelapha indle, izinqubo zokwelapha ezinomthelela neziyinhloko zivame ukuhilela ukugeleza kwamanzi amdaka anezinhlayiya ezahlukahlukene. Amapayipi emvelo anezinhlayiya zerabha angamelana ngempumelelo nokungqubuzana okubangelwa yilezi zinhlayiya ngenkathi ehambisana ne-i-flowmeter kagesi.Ulwelwesi lwerabha lwemvelo luhlinzeka ngobuso obungaphakathi obubushelelezi, lunciphisa ukumelana kokugeleza futhi luqinisekise ukulinganiswa okunembile kokugeleza nge-flowmeter kagesi.

1.2 Irabha Yokwenziwa (isib., i-Neoprene)

Amarabha okwenziwa afana ne-neoprene anokumelana kwamakhemikhali okuthuthukisiwe uma kuqhathaniswa nerabha yemvelo. Amapayipi anezimbobo ze-Neoprene afanelekela ukulinganisa uketshezi olubola kancane, njenge-acid ethile ebuthakathaka noma ama-alkali ngaphakathi kobubanzi obuthile bokuhlushwa. Ezinqubweni zezimboni lapho kunezinto zokuhlanza zamakhemikhali ezithuthwa ngamapayipi, amapayipi anezimbobo ze-neoprene angasetshenziswa kanyeama-flowmeter kagesi.Ulwelwesi lwe-neoprene aluvikeli nje kuphela ipayipi ekuhlaselweni ngamakhemikhali kodwa futhi lugcina ubuqotho bensimu kagesi esetshenziselwa ukulinganisa ukugeleza, okuvumela ukunqunywa okunembile kwesilinganiso sokugeleza kwalezi ziketshezi ezisabela ngamakhemikhali.

2. Ama-Lining e-Fluoropolymer

2.1 I-PTFE (i-Polytetrafluoroethylene)

I-PTFE idume ngokumelana kwayo okumangalisayo kwamakhemikhali, ikwazi ukumelana nohlu olubanzi lwamakhemikhali agqwalisayo kakhulu, okuhlanganisa ama-asidi aqinile, izisekelo, kanye nama-oxidizing agents. Amapayipi afakwe i-PTFE avame ukusetshenziswa embonini yamakhemikhali, ekukhiqizeni imithi, nasekukhiqizweni kwe-semiconductor. Esitshalo samakhemikhali lapho kudluliswa khona amakhemikhali anamandla njenge-sulfuric acid egxilile noma i-hydrofluoric acid, i-flowmeter ye-electromagnetic ingafakwa epayipini elifakwe i-PTFE. Ulwelwesi lwe-PTFE luqinisekisa ukuthi ipayipi alilinyazwa yi-medium egqwalisayo, futhi izakhiwo zalo ezingahambisani nogesi kanye nezingaguquguquki amakhemikhali aziphazamisi isimiso sokulinganisa i-electromagnetic. Lokhu kuvumela ukulinganiswa kokugeleza okunembile ngisho nasezindaweni zamakhemikhali ezinzima kakhulu.

2.2 I-FEP (i-Fluorinated Ethylene Propylene)

I-FEP ingenye into yokwakheka kwe-fluoropolymer. Inokumelana kwamakhemikhali okufanayo ne-PTFE kodwa inezinzuzo ezithile mayelana nokucutshungulwa kanye nokucaca. Amapayipi anemigqa ye-FEP avame ukusetshenziswa ekusetshenzisweni lapho kudingeka ukuhlolwa okubonakalayo kokugeleza koketshezi ngaphezu kokulinganiswa okunembile kokugeleza. Isibonelo, kwezinye izindlela zamakhemikhali ezisetshenziswa elabhorethri noma ekukhiqizweni koketshezi oluhlanzekile kakhulu embonini yemithi, amapayipi anemigqa ye-FEP angahlanganiswa neama-flowmeter kagesiUkucaca kwe-FEP kwenza opharetha bakwazi ukubona isimo sokugeleza koketshezi, kuyilapho i-flowmeter kagesi inikeza idatha yesilinganiso sokugeleza esinembile.

3. Izindwangu zobumba

Amapayipi anezimbobo ze-ceramic afaneleka kakhulu ezisetshenziswayo ezidinga ukumelana nokushisa okuphezulu kanye nokumelana nokuguguleka okuhle kakhulu. Ama-ceramic anendawo yokuncibilika ephezulu futhi angagcina izakhiwo zawo zemishini nezamakhemikhali emazingeni okushisa aphezulu. Ezimbonini ezifana nokukhiqizwa kwamandla, lapho kukhona khona amagesi ashisayo aqukethe umlotha noma ama-slurry anokushisa okuphezulu, amapayipi anezimbobo ze-ceramic angasetshenziswa ngama-flowmeter kagesi. Ulwelwesi lwe-ceramic luvikela ipayipi emphumela wokuguguleka kwezinhlayiya zejubane eliphezulu oketshezini, futhi i-flowmeter kagesi ingalinganisa ngokunembile izinga lokugeleza kwalawa manzi anokushisa okuphezulu. Nakuba ama-ceramics eyinto ebuthakathaka, ukufakwa kahle kanye nokwakhiwa kohlelo lwamapayipi kungaqinisekisa ukusebenza kwawo okuthembekile kwesikhathi eside kuhlangene nama-flowmeter kagesi.

Ekuphetheni,ama-flowmeter kagesiingasetshenziswa ngempumelelo ngamapayipi afakwe irabha (yemvelo neyokwenziwa), ama-fluoropolymers (i-PTFE ne-FEP), kanye ne-ceramics. Ukukhethwa kwezinto zokufaka ulwelwesi kuncike ezicini ezithile ze-medium elinganisiwe, njengokwakheka kwamakhemikhali ayo, izinga lokushisa, kanye nokuguguleka, ukuqinisekisa ukulinganiswa kokugeleza okunembile nokuthembekile.
