Pakuwunika chilengedwe, chitetezo cha mafakitale, ndi kusanthula kwa labotale,mapampu a mpweya waung'onondi zinthu zofunika kwambiri mu makina oyezera mpweya. Pofufuza mpweya wowononga, kusankha zipangizo zopopera kumakhudza mwachindunji kulondola kwa zotsatira za kusanthula ndi moyo wa ntchito ya zidazo. Kusankha zinthu zolakwika kungawononge ubwino wa deta komanso kungayambitsepampu ya mpweya ya mini dckulephera.

Nkhaniyi ikupereka malangizo omveka bwino komanso othandiza okhudza kusankha zinthu m'njira yosavuta.

Mfundo Yaikulu: Yang'anani pa Zigawo Zokha Zomwe Zikukhudzana ndi Gasi

Mu mapampu ang'onoang'ono, zigawo zokha zomwe zimalumikizana mwachindunji ndi mpweya zimafunika kuganiziridwa kuti zisawonongeke ndi dzimbiri. Izi nthawi zambiri zimatchedwa zigawo za "wet end" ndipo makamaka zimaphatikizapo:

1, Mutu/Chivundikiro cha Pampu: Chimapereka chithandizo cha kapangidwe kake ndipo chili ndi malo akuluakulu olumikizirana ndi mpweya.

2、Diaphragm: Imayang'anira kusamutsa mpweya, imafuna kusinthasintha kwabwino komanso kukana kutopa.

3, Ma Valve Plates/Ma Valve: Yang'anirani momwe mpweya umayendera, zomwe zimafuna kuyankhidwa mwachangu komanso kutsekedwa bwino.

Zipangizo Zofunika: Zigawo za "Wet End" — Kusankha Pakati pa Mapulasitiki ndi Elastomers

Zinthu zomwe zili mu "wet end" makamaka zimakhala ndi zinthu monga mapulasitiki ogwira ntchito kwambiri (ogwiritsidwa ntchito popangira mitu ya mapampu) ndi ma elastomer ogwira ntchito kwambiri (ogwiritsidwa ntchito popangirama diaphragm ndi ma valvePansipa, timvetsetsa makhalidwe a zipangizozi poyang'ana kwambiri pa zigawo za "mapeto onyowa".

Zipangizo za Mutu wa Pampu: Kulinganiza Mphamvu ndi Kukana Kudzimbiritsa

Dzina la Zinthu	Chidule	Makhalidwe Ofunika ndi Mapulogalamu	Mitundu Yoyenera ya Gasi
Polyphenylene Sulfide	PPS	Kugwira ntchito bwino konsekonse. Mphamvu yayikulu yamakina, kukana kutentha bwino, komanso kupirira kwambiri ma acid, alkali, ndi zosungunulira. Amagwiritsidwa ntchito kwambiri mu kusanthula mpweya wa flue (SO₂, NOx).	Ma asidi ofooka, alkali ofooka, zosungunulira wamba
Polyvinylidene Fluoride	PVDF	Yoyenera ma oxidizer amphamvu. Yolimba kwambiri ku mpweya wamphamvu wooxidiza monga Cl₂, O₃, ndi ma acid amphamvu.	Oxidizer amphamvu, ma asidi amphamvu
Polytetrafluoroethylene	PTFE	Ndi yopanda mankhwala. Siigwira ntchito ndi mankhwala aliwonse. Yoyenera malo omwe amafuna kuyera kwambiri kapena okhala ndi mpweya wovuta komanso wovuta.	Pafupifupi mankhwala onse

Malangizo Othandiza: Ngati mpweya uli ndi chlorine kapena ozone wambiri, ndibwino kusankha mutu wa pampu wa PVDF kapena PTFE, kupewa PPS.

Zipangizo za Diaphragm/Valve: Kulinganiza Kutanuka ndi Kukhazikika

Ma diaphragm ndi ma valve ayenera kukhala otanuka komanso osapsa ndi dzimbiri.

Dzina la Zinthu	Chidule	Makhalidwe Ofunika ndi Mapulogalamu	Mtengo ndi Kugwiritsa Ntchito
Polyphenylene Sulfide	EPDM	Mtengo wotsika. Kukana bwino ma acid, alkali, ndi nthunzi ya madzi. Komabe, ili ndi kukana kochepa kwa mafuta ndi zinthu zambiri zosungunulira zachilengedwe (VOCs).	Mtengo wotsika, woyenera mpweya wamba wowononga wopanda VOCs.
Polyvinylidene Fluoride	FKM	Yogwira ntchito zosiyanasiyana. Yolimba bwino ku zinthu zosungunulira zachilengedwe, ma hydrocarbon (VOCs), ndi ma asidi amphamvu. Elastomer yomwe imagwiritsidwa ntchito kwambiri pofufuza mafakitale.	Mtengo wapakati, magwiridwe antchito odalirika, oyenera malo ambiri amafakitale.
Polytetrafluoroethylene	FFKM	Kukana dzimbiri kwabwino kwambiri. Kugwira ntchito kwa mankhwala pafupi ndi PTFE pomwe kumasunga kusinthasintha kwa rabara. Kulimbana ndi zinthu zonse za mankhwala.	Mtengo wokwera kwambiri, umagwiritsidwa ntchito pokhapokha pa ntchito zovuta kwambiri, zofunika kwambiri pomwe kusokoneza si njira yabwino.

Malangizo Othandiza: Ngati mpweya uli ndi ma hydrocarbon kapena ma organic solvents (VOCs), musasankhe EPDM. M'malo mwake, sankhani FKM kapena FFKM.

Njira Yosankhira Zinthu Patatu: Kodi Mungasankhe Motani Moyenera?

Kusankha zinthu sikutanthauza kusankha njira yokwera mtengo kwambiri, koma kukhudzana ndi momwe zinthu zilili.

Gawo 1: Dziwani Kapangidwe ka Mpweya ndi Kuchuluka Kwake

Ichi ndiye maziko ofunikira kwambiri pakusankha zinthu. Muyenera kudziwa gawo lowononga kwambiri mu mpweya lomwe muyenera kuyeza komanso kuchuluka kwake kwakukulu.

• Chitsanzo Choyamba: Mpweya wamba wa flue (wochepa SO₂、NOx): Mutu wa pampu ya PPS + FKM diaphragm/ma valavu.
• Chitsanzo Chachiwiri: Kusanthula kwa klorini mu zomera za chlor-alkali (Cl₂ yochuluka kwambiri): Mutu wa pampu wa PVDF + diaphragm/ma valavu a FFKM.

Gawo 2: Ganizirani za Mphamvu ya Kutentha

Kutentha kumathandizira dzimbiri. Chinthu cholimba kutentha kwa chipinda chingalephereke msanga kutentha kwambiri. Nthawi zonse onani ma chart ogwirizana ndi zinthu kutengera kutentha kwenikweni komwe kumagwiritsidwa ntchito.

Gawo 3: Kuwerengera Mtengo ndi Chiwopsezo

• Kugwiritsa Ntchito Pangozi Yochepa / Nthawi Zonse: Sankhani kuphatikiza kwa PPS/FKM kuti mupeze chiŵerengero chabwino kwambiri cha mtengo ndi magwiridwe antchito.
• Kugwiritsa Ntchito Pangozi Yaikulu / Kofunika Kwambiri: Sankhani kuphatikiza kwa PVDF/PTFE/FFKM. Ngakhale kuti ndalama zoyambira zimakhala zambiri, zimapereka nthawi yayitali yogwirira ntchito komanso kudalirika kwakukulu pakusanthula, zomwe zimatsimikizira kuti ndizotsika mtengo kwambiri pakapita nthawi.

Chikumbutso: Pakuwunika mpweya wowononga, kugwirizana kwa zinthu ndikofunikira kwambiri. Kulephera kwa zinthu sikungobweretsa kuwonongeka kokhapampu yaying'ono ya mpweyakoma mwinanso mu gulu la deta yolakwika yosanthula.
