Ekuqapheni imvelo, ukuphepha kwezimboni, kanye nokuhlaziywa kwelabhorethri,amaphampu omoya amancaneziyizingxenye ezibalulekile ezinhlelweni zokuthatha amasampula egesi. Lapho kuhlaziywa amagesi agqwalisayo, ukukhetha izinto zokupompa kuthinta ngqo ukunemba kwemiphumela yokuhlaziya kanye nokuphila kwenkonzo yemishini. Ukukhetha izinto ezingalungile kungalimaza ikhwalithi yedatha futhi kuholele ngisho nasekuipompo yomoya ye-mini dcukwehluleka.

Lesi sihloko sinikeza inkomba ecacile nesebenzayo yokukhetha izinto ngendlela eqondile.

Isimiso Esiyinhloko: Gxila Kuphela Ezingxenyeni Ezithintana Negesi

Kumaphampu amancane, yizingxenye ezithinta igesi ngqo kuphela ezidinga ukucatshangelwa ukumelana nokugqwala. Lezi zivame ukubizwa ngokuthi izingxenye "ezimanzi" futhi zifaka phakathi:

1, Ikhanda/Isembozo Sephampu: Inikeza ukwesekwa kwesakhiwo futhi inendawo enkulu yokuxhumana negesi.

2. I-Diaphragm: Inesibopho sokudluliselwa kwegesi, idinga ukuguquguquka okuhle kanye nokumelana nokukhathala.

3, Amapuleti/Amavalvu E-Valve: Lawula indlela yokugeleza kwegesi, okudinga impendulo esheshayo kanye nokuvalwa okuhle.

Izinto Ezibalulekile: Izingxenye "Zokuphela Okumanzi" — Ukukhetha Phakathi Kwepulasitiki Nama-Elastomer

Izingxenye "zokuphela okumanzi" ikakhulukazi zakhiwe ngezinto ezifana nepulasitiki esebenza kahle kakhulu (esetshenziselwa amakhanda ephampu) kanye nama-elastomer asebenza kahle kakhulu (asetshenziselwaama-diaphragm nama-valveNgezansi, sizoqonda izici zalezi zinto ngokugxila ezingxenyeni "ezimanzi".

Izinto Zokukhanda Kwephampu: Ukulinganisela Amandla Nokumelana Nokugqwala

Igama Lezinto	Isifinyezo	Izici Eziyinhloko kanye Nezicelo	Izinhlobo Zegesi Ezifanele
I-Polyphenylene Sulfide	I-PPS	Ukusebenza okuhle kakhulu. Amandla aphezulu okusebenza, ukumelana okuhle nokushisa, kanye nokubekezelela okubanzi ama-asidi, ama-alkali, kanye nezinyibilikisi. Ivame ukusetshenziswa ekuhlaziyweni kwegesi yomoya (SO₂, NOx).	Ama-asidi abuthakathaka, ama-alkali abuthakathaka, izinyibilikisi ezivamile
I-Polyvinylidene Fluoride	I-PVDF	Ifanelekela ama-oxidizer aqinile. Imelana kahle kakhulu namagesi aqinile okuxoxisa njenge-Cl₂, O₃, nama-asidi aqinile.	Ama-oxidizer aqinile, ama-asidi aqinile
I-Polytetrafluoroethylene	I-PTFE	Ayisebenzi ngamakhemikhali. Ayisebenzi nhlobo nanoma yimaphi amakhemikhali. Ifanelekela izindawo ezifuna ubumsulwa obukhulu noma ezixubene negesi eyinkimbinkimbi neqinile.	Cishe wonke amakhemikhali

Iseluleko Esiwusizo: Uma igesi iqukethe amazinga aphezulu e-chlorine noma i-ozone, kunconywa ukukhetha ikhanda lephampu le-PVDF noma le-PTFE, ugweme i-PPS.

Izinto Zokwenza I-Diaphragm/Valve: Ukulinganisela Ukunwebeka Nokuzinza

Ama-diaphragm nama-valve kudingeka abe nokunwebeka kuyilapho futhi ekwazi ukumelana nokugqwala.

Igama Lezinto	Isifinyezo	Izici Eziyinhloko kanye Nezicelo	Izindleko Nokusebenza
I-Polyphenylene Sulfide	I-EPDM	Izindleko eziphansi. Ukumelana okuhle nama-asidi, ama-alkali, kanye nomhwamuko wamanzi. Kodwa-ke, ayimelani kahle namafutha kanye nezincibilikisi eziningi eziphilayo (ama-VOC).	Izindleko eziphansi, ezifanele amagesi avamile agqwalisayo angenawo ama-VOC.
I-Polyvinylidene Fluoride	I-FKM	Isebenza ngezindlela eziningi. Ukumelana okuhle nezinyibilikisi eziphilayo, ama-hydrocarbon (ama-VOC), nama-asidi aqinile. I-elastomer esetshenziswa kakhulu ekuhlaziyweni kwezimboni.	Izindleko ezimaphakathi, ukusebenza okuthembekile, ezifanele izindawo eziningi zezimboni.
I-Polytetrafluoroethylene	I-FFKM	Ukumelana nokugqwala okungcono kakhulu. Ukusebenza kwamakhemikhali kusondele ku-PTFE ngenkathi kugcinwa ukuqina kwerabha. Kumelana cishe nazo zonke izinhlobo zamakhemikhali.	Izindleko ziphezulu kakhulu, zisetshenziselwa kuphela izinhlelo zokusebenza ezinzima kakhulu, ezibalulekile lapho ukuphazamiseka kungeyona inketho.

Iseluleko Esiwusizo: Uma igesi iqukethe noma yimaphi ama-hydrocarbon noma izinyibilikisi eziphilayo (ama-VOC), ungakhethi i-EPDM. Kunalokho, khetha i-FKM noma i-FFKM.

Inqubo Yesinqumo Esinezinyathelo Ezintathu: Ungakhetha Kanjani Ngokufanele?

Ukukhetha izinto ezibonakalayo akukhona ukukhetha inketho ebiza kakhulu, kodwa mayelana nokufanisa isimo sangempela.

Isinyathelo 1: Thola Ukwakheka Kwegesi Nokuhlushwa Kwayo

Lesi yisisekelo esibaluleke kakhulu sokukhethwa kwezinto. Udinga ukwazi ingxenye egqwala kakhulu kugesi okufanele ilinganiswe kanye nokuhlushwa kwayo okuphezulu.

• Isibonelo Sokuqala: Igesi yomoya ojwayelekile (umthamo ophansi SO₂、NOx): Ikhanda lephampu le-PPS + i-FKM diaphragm/amavalvu.
• Isibonelo Sesibili: Ukuhlaziywa kwe-chlorine ezitshalweni ze-chlor-alkali (i-Cl₂ ephezulu): Ikhanda lephampu le-PVDF + i-FFKM diaphragm/amavalvu.

Isinyathelo 2: Cabanga Ngomthelela Wezinga Lokushisa

Izinga lokushisa lisheshisa ukugqwala. Into engamelana nezinto ekushiseni kwegumbi ingase yehluleke ngokushesha ekushiseni okuphezulu. Njalo hlola amashadi okuhambisana nezinto asekelwe ekushiseni kwangempela kokusebenza.

Isinyathelo 3: Ibhalansi Yezindleko Nengozi

• Izingozi Eziphansi/Izicelo Ezijwayelekile: Khetha inhlanganisela ye-PPS/FKM ukuze uthole isilinganiso esihle kakhulu sezindleko nokusebenza.
• Ingozi Ephakeme / Izinhlelo Zokusebenza Ezibalulekile: Khetha inhlanganisela ye-PVDF/PTFE/FFKM. Nakuba ukutshalwa kwezimali kokuqala kuphakeme, kunikeza impilo yesevisi ende kanye nokuthembeka okuphezulu kokuhlaziya, okufakazela ukuthi kuyonga kakhulu ngokuhamba kwesikhathi.

Isikhumbuzi: Ekuhlaziyweni kwegesi egqwalisayo, ukuhambisana kwezinto kubalulekile. Ukwehluleka kwezinto akugcini nje ngokubangela ukulimalaiphampu yomoya encanekodwa kungenzeka futhi kube yiqoqo ledatha yokuhlaziya eyiphutha.
