Molao-motheo oa Bohlokoa: Tsepamisa Maikutlo Feela Likarolong Tse Amanang le Khase

Lipompong tse nyane, ke likarolo tse amang khase ka ho toba feela tse hlokang ho nahanoa bakeng sa ho hanyetsa mafome. Tsena hangata li bitsoa likarolo tsa "metsi a ho qetela" 'me haholo-holo li kenyelletsa:

1, Hlooho/Sekoahelo sa Pompo: E fana ka tšehetso ea sebopeho 'me e na le sebaka se seholo ka ho fetisisa sa ho kopana le khase.

2、Diaphragm: E ikarabella bakeng sa phetiso ea khase, e hlokang ho tenyetseha hantle le ho hanyetsa mokhathala.

3, Lipoleiti/Li-valve tsa Li-valve: Laola tsela eo khase e phallang ka eona, e hlokang karabelo e potlakileng le ho koaloa hantle.

Lisebelisoa tsa Bohlokoa: Likarolo tsa "Wet End" — Khetho Pakeng tsa Plastiki le Elastomer

Likarolo tsa "metsi a qetellong" haholo-holo li na le thepa e kang polasetiki e sebetsang hantle (e sebelisoang bakeng sa lihlooho tsa pompo) le li-elastomer tse sebetsang hantle (tse sebelisetsoangli-diaphragm le li-valve). Ka tlase, re tla utloisisa litšobotsi tsa thepa ena re shebane le likarolo tsa "metsi a qetellong".

Lisebelisoa tsa Hlooho ea Pompo: Ho Leka-lekanya Matla le Khanyetso ea ho Sila

Lebitso la Thepa	Khutsufatso	Litšobotsi tsa Bohlokoa le Litšebeliso	Mefuta e Loketseng ea Khase
Polyphenylene Sulfide	PPS	Tshebetso e ntle ka kakaretso. Matla a phahameng a mechini, ho hanyetsa mocheso hantle, le mamello e pharaletseng ho li-acid, alkali le li-solvents. E sebelisoa hangata tlhahlobong e ngata ea khase ea flue (SO₂, NOx).	Li-acid tse fokolang, li-alkali tse fokolang, li-solvent tse tloaelehileng
Fluoride ea Polyvinylidene	PVDF	E loketse di-oxidizer tse matla. E hanela hantle dikgase tse matla tse oxidizer tse kang Cl₂, O₃, le di-acid tse matla.	Li-oxidizer tse matla, li-acid tse matla
Polytetrafluoroethylene	PTFE	Ha e na lik'hemik'hale. Ha e sebetse hantle ka lik'hemik'hale life kapa life. E loketse libaka tse hlokang bohloeki bo phahameng ka ho fetisisa kapa tse nang le metsoako e rarahaneng le e matla ea khase.	Lik'hemik'hale tse batlang li le teng kaofela

Keletso e Sebetsang: Haeba khase e na le chlorine kapa ozone e ngata, ho kgothaletswa ho kgetha hlooho ya pompo ya PVDF kapa PTFE, ho qoba PPS.

Lisebelisoa tsa Diaphragm/Valve: Ho Leka-lekanya ho tenyetseha le botsitso

Li-diaphragm le li-valve li hloka ho tenyetseha ha ka nako e ts'oanang li boetse li hanela mafome.

Lebitso la Thepa	Khutsufatso	Litšobotsi tsa Bohlokoa le Litšebeliso	Litšenyehelo le Tšebeliso
Polyphenylene Sulfide	EPDM	Litšenyehelo tse tlase. Ho hanyetsa hantle li-acid, alkali le mouoane oa metsi. Leha ho le joalo, ha e na ho hanyetsa hantle oli le boholo ba li-solvents tsa tlhaho (VOCs).	Theko e tlase, e loketse likhase tse tloaelehileng tse senyang tse se nang li-VOC.
Fluoride ea Polyvinylidene	FKM	E sebetsa ka mefuta e fapaneng. E hanyetsa hantle di-solvent tsa tlhaho, di-hydrocarbon (VOCs), le di-acid tse matla. Elastomer e sebediswang haholo tlhahlobong ya diindasteri.	Litšenyehelo tse itekanetseng, ts'ebetso e tšepahalang, e loketse libaka tse ngata tsa indasteri.
Polytetrafluoroethylene	FFKM	Ho hanyetsa mafome ho molemo ka ho fetisisa. Tshebetso ya dikhemikhale e haufi le PTFE ha e ntse e boloka ho tenyetseha ha rabara. E hanela hoo e ka bang dikhemikhale tsohle.	Theko e phahameng haholo, e sebelisoa feela bakeng sa lits'ebetso tse thata haholo, tsa bohlokoa haholo moo ho sitisoa e seng khetho.

Keletso e Sebetsang: Haeba khase e na le li-hydrocarbon kapa li-solvent tsa tlhaho (li-VOC), u se ke ua khetha EPDM. Ho e-na le hoo, khetha FKM kapa FFKM.

Mokhoa oa ho Etsa Qeto ea Mehato e Meraro: Mokhoa oa ho Khetha ka Nepo?

Khetho ea thepa ha se taba ea ho khetha khetho e turang ka ho fetisisa, empa ke taba ea ho bapisa boemo ba sebele.

Mohato oa 1: Hlalosa Sebopeho sa Khase le Mahloriso

Ena ke motheo oa bohlokoa ka ho fetisisa bakeng sa khetho ea thepa. U hloka ho tseba karolo e senyang ka ho fetisisa khaseng e lokelang ho lekanngoa le mahloriso a eona a phahameng ka ho fetisisa.

• Mohlala oa Pele: Khase e tloaelehileng ea flue (matla a tlase SO₂、NOx): Hlooho ea pompo ea PPS + diaphragm/valve ea FKM.
• Mohlala oa Bobeli: Tlhahlobo ea chlorine limela tsa chlor-alkali (matla a phahameng a Cl₂): Hlooho ea pompo ea PVDF + diaphragm/valve ea FFKM.

Mohato oa 2: Nahana ka Tšusumetso ea Mocheso

Mocheso o potlakisa ho bola. Sesebediswa se hanelang thepa mochesong wa kamore se ka hloleha kapele mochesong o phahameng. Kamehla sheba dichate tse tsamaellanang le thepa tse itshetlehileng mochesong wa sebele wa tshebetso.

Mohato oa 3: Tekanyo ea Litšenyehelo le Kotsi

• Litšebeliso tse Tlase tsa Kotsi / Mokhoa oa Kemiso: Khetha motsoako oa PPS/FKM bakeng sa karolelano e ntle ka ho fetisisa ea litšenyehelo le ts'ebetso.
• Litšebeliso tse Kotsi e Phahameng / Tse Bohlokoa: Khetha motsoako oa PVDF/PTFE/FFKM. Leha letsete la pele le le holimo, le fana ka bophelo bo bolelele ba ts'ebeletso le ts'epo e phahameng ea tlhahlobo, e leng se pakang hore e theko e tlase ha nako e ntse e ea.
