Yini Ebangela Ukuvaleka Kwezihlungi Ezihlanganisiwe Futhi Ungakuvimbela Kanjani?

Izihlungi ezifakwe i-sintered ziyavaleka ngenxa yokuthiizinhlayiya ziqoqana kancane kancane ngaphakathi kwesakhiwo esinezimbobo futhi zidlule amandla aso okugcinaUma lokhu sekwenzekile, ukumelana nokugeleza kwamanzi kuyanda ngokushesha, okuholela ekwehleni okukhulu kwengcindezi kanye nokwehla kokusebenza kahle kokuhlunga.

Ezindaweni zangempela zezimboni, ukuvaleka kwemisebenzi akuvamile ukubangelwa yinto eyodwa. Ngokuvamile kuba umphumela wezimo zokusebenza eziningi ezisebenza ndawonye.

Izici ezibalulekile ezibangela lokhu zifaka:

■ Umthwalo wezinhlayiya eziningi kakhulu oketshezini oluphezulu noma igesi

■ Ukukhetha okungalungile kwesilinganiso se-micron (kuhle kakhulu kuhlelo lokusebenza)

■ I-media enamandla kakhulu noma enamathelayo ebamba izinhlayiya kalula

■ Ukuntuleka kwezigaba ezifanele zokuhlunga ngaphambi kokufakwa

■ Ukungahlanzwa noma ukulungiswa kwemijikelezo enganele

Kalula nje, isihlungi esicwebezelayo siyahluleka uma sichayeka ekungcoleni okukhulu kunalokho isakhiwo saso sembobo esiklanyelwe ukukuphatha, futhi ayikho indlela ephumelelayo yokukhulula noma ukususa izinhlayiya ezivalelekile.

Indlela Yokuvimbela Ukuvaleka (Impendulo Yobunjiniyela Obusebenzayo)

Ukuvimbela ukuvaleka kudinga ukwenziwa ngcono kwezinga lesistimu kunokuthembela ekushintsheni isihlungi njalo.

Onjiniyela ngokuvamile basebenzisa amasu alandelayo afakazelwe:

■ Khetha usayizi wembobo ofanele (isilinganiso se-micron) ngokusekelwe kumthwalo wezinhlayiya zangempela, hhayi ukunemba kokuhlunga okucatshangwayo

■ Sebenzisa izinhlelo zokuhlunga zangaphambi kwezigaba eziningi ukuze unciphise umthwalo ongcolile ngaphambi kokufinyelela into ehlanjululwe

■ Qapha umehluko wokucindezela (ΔP) ukuze uthole ukuvaleka kwesigaba sokuqala ngaphambi kokwehla kokusebenza

■ Sebenzisa izindlela zokuhlanza njalo njengokuhlanza nge-backflushing noma nge-ultrasound kuye ngokuthi uhlelo luklanywe kanjani

■ Khetha izinto ezingagqwali njengensimbi engagqwali engu-316L noma i-Inconel ezindaweni zokusebenza ezinzima

Phakathi kwalezi zindlela, ukwenza ngcono ukwakheka kohlelo kuyisici esibaluleke kakhulu ekwandiseni isikhathi sokuphila kwesihlungi nokugcina ukusebenza okuzinzile.

Ukuqonda Okubalulekile Konjiniyela Nabathengi

Ukwehluleka okuningi kwesihlungi esincibilikisiwe kuyabikezelwa futhi kungavinjelwa uma uhlelo luklanywe futhi lunakekelwa kahle.

Uma ukuvaleka kwenzeka njalo, ngokuvamile kubonisa inkinga eyodwa noma ngaphezulu kwesistimu elandelayo:

■ Uhlelo lokuhlunga aluncane kakhulu ukuze luhambisane nomthwalo wangempela wokungcola

■ I-media ayilungiswa kahle ngaphambi kokungena esigabeni sokuhlunga

■ Isu lokulungisa alikho noma alilungiselelwanga izimo zokusebenza

Iyini Isihlungi Esicwebezelayo Futhi Kungani Sivaleka Kalula Ekusetshenzisweni Kwezimboni

Isihlungi esisikiwe siyinto yokuhlunga insimbi enezimbobo eyenziwe ngokuhlanganisa nokususa izimpushana zensimbi njengensimbi engagqwali engu-316L, ithusi, noma i-nickel alloys ngaphansi kwendawo yokuncibilika kwazo.

Le nqubo idala isakhiwo esiqinile, esixhumene sembobo esivumela amagesi noma uketshezi ukuthi kudlule ngenkathi kubanjwa izinhlayiya eziqinile ngaphakathi kokujula kwemidiya.

Ngokungafani nezihlungi zangaphezulu njengezihlungi ze-mesh noma zephepha, izihlungi ezisinki zisebenza njengemidiya yokuhlunga okujulile, okusho ukuthi izinhlayiya zivaleleke kokubili ebusweni nangaphakathi kwenethiwekhi yangaphakathi ye-pore.

Kungani Izihlungi Ezihlanganisiwe Zisetshenziswa Kabanzi Embonini

Zisetshenziswa kabanzi ngoba zinikeza:

■ Amandla aphezulu omshini kanye nokumelana nokucindezela

■ Ukuqina okuhle kakhulu kokushisa ezindaweni ezinokushisa okukhulu

■ Ukumelana nokugqwala okunamandla, ikakhulukazi ekusetshenzisweni kwensimbi engagqwali engu-316L

■ Ukuhlanzeka okuhle kakhulu ngokusebenzisa i-backflushing noma i-ultrasound cleaning

■ Impilo yesevisi ende enokusebenza okuzinzile kokuhlunga

Izicelo ezijwayelekile zifaka phakathi ukucubungula amakhemikhali, ukuhlunga igesi, ukukhiqizwa kwemithi, izinhlelo zokudla neziphuzo, kanye nokukhiqizwa kwe-semiconductor.

Kungani Besalokhu Bevalekile Naphezu Kwezinzuzo Zabo

Nakuba izihlungi ezisikiwe ziqinile kakhulu, isakhiwo sazo sokuhlunga okujulile yisona futhi isizathu sokuvaleka kancane kancane ngokuhamba kwesikhathi.

Ukuvaleka kwenzeka ngenxa yokuthi:

■ Izinhlayiya zingena ngale kobuso futhi ziqongelela ngaphakathi kweziteshi zemigodi

■ Izendlalelo ezijulile zesakhiwo ziyavimbeka futhi kunzima ukuzihlanza

■ Izinhlayiya ezincane ziyaqina kancane kancane ngaphakathi kwenethiwekhi yezimbobo

■ Ukunamathela noma ukubekwa kwamakhemikhali kwenzeka ngaphakathi kwesakhiwo esinezimbobo

Lokhu kuphumela ekunciphiseni kancane kancane usayizi wembobo osebenzayo, okwandisa ukwehla kwengcindezi futhi kunciphisa ukusebenza kahle kohlelo.

Ngakho-ke ukuvaleka kuyinqubo eqhubekayo kunokuba kube ukwehluleka okungazelelwe.

Izimbangela Eziyi-6 Eziphambili Zokuvaleka Kwesihlungi Esicwebezelayo

Ukuvaleka kwesihlungi esihlanganisiwe kuwumphumela wezici eziningi ezisebenzisanayo kunokuba kube imbangela eyodwa.
