[Isingeniso Somkhiqizo] Izihlahla ze-tungsten carbide: ikhambi elithembekile elingagugi ngaphansi kwezimo zokusebenza ezinzima

Njengengxenye ebalulekile yokuvikela umgodi wephampu, ukuqina kwesikhafu somgodi kuthinta ngqo ukuzinza kwezindleko zokusebenza kwemishini nokugcinwa kwayo. Njengemishini eyinhloko yokulawula uketshezi, amavalvu ephampu asetshenziswa kabanzi emikhakheni eyahlukene njengezimayini, imboni yamakhemikhali, amandla, insimbi, njll. Kodwa-ke, lapho ubhekene nemidiya ebhula njenge-slurry nodaka, noma uketshezi oluqinile olubolayo njenge-asidi, i-alkali, nosawoti, noma izimo zokusebenza ezimbi kakhulu njengokushisa okuphezulu nokucindezela okuphezulu, insimbi engagqwali evamile, insimbi ecinyiwe, nezinye izinto ngokuvamile azinamandla, zivame ukuguga, ukugqwala, ukuguqulwa, nezinye izinkinga, okuholela ekunciphiseni ukusebenza kahle kwephampu, ukuvuza kwesivalo, ukushintshwa njalo, kanye nokwanda kwezindleko zokungasebenzi kanye nokugcinwa.

Umkhawulo wokusebenza kwezinto zokwakha uba yisithiyo esibalulekile esivimbela ukuthembeka kanye nesikhathi sokuphila kwemishini yepompo kanye nevalvu.

I-Tungsten carbide bushessezibe yisinqumo esithembekile sokuzivumelanisa nezimo zokusebenza ezinzima ngenxa yezakhiwo zazo zezinto ezizinzile.

CHA.01Izinselele zesimo sokusebenza embonini yamaphampu nama-valve

Izimo zokusebenza zemishini ziyinkimbinkimbi futhi ziyahlukahluka, futhi izimo ezahlukene zokusetshenziswa zibeka izidingo ezihlukile kodwa eziqinile ngokulinganayo ezintweni zokwakha:

1.Isimo sokuguguleka okunolaka:Uma imishini efana namaphampu odaka kanye namaphampu odaka ithutha imidiya equkethe izinhlayiya eziqinile, ubuso besikhafu somgodi bubhekana nokuguguleka okuqhubekayo kwemvamisa ephezulu kanye nokuguguleka okunolaka. Izinto zensimbi ezivamile ziguguleka ngokushesha kakhulu ngaphansi kwezimo ezinjalo, okuholela ekunakekelweni njalo kanye nokulahlekelwa okukhulu ngenxa yokuvalwa kwemishini.

2.Isimo sokugqwala okunamandla：Amaphampu ezinqubo zamakhemikhali, amaphampu okwelapha amanzi angcolile, kanye neminye imishini ivame ukuxhumana nezinto ezigqwalisayo ezifana nama-asidi, ama-alkali, nosawoti. Nakuba izinto zensimbi engagqwali zinokumelana nokugqwala okuthile, zisathambekele ekugqwaleni okubangelwa yizimbobo, ukuqhekeka kokugqwala kokucindezeleka, kanye nezinye izinkinga ezindaweni ezinokushisa okuphezulu kanye nokuhlushwa okuphezulu.

3.Isimo sokusebenza sokushisa okuphezulu:Izinga lokushisa lokusebenza kwemishini efana namaphampu kawoyela oshisayo namaphampu okushisa okuphezulu livame ukufinyelela ku-300-400 ° C. Ngemva kwalolu hlu lokushisa, ukusebenza kwensimbi evamile kuyawohloka kakhulu, ubulukhuni buyancipha, futhi ukuguquguquka kuyaqina, okusongela kakhulu ukuphepha kokusebenza kwemishini.

CHA.02Izinzuzo zobuchwepheshe zezinto eziqinile ze-alloy

Izinkinga ezivamile ngemikhono yeshafti evamile

1. Ukuguga okusheshayo, ukuvuleka kokusebenza okwandisiwe, kanye nokwehla kokusebenza kahle kwephampu;

2. Kulula ukugqwala nokugqwala, okubangela ukuvuza okuphakathi nendawo;

3. Ukusebenza kwehla ngaphansi kwezimo zokushisa okuphezulu, okwenza kube lula ukuguquguquka nokuqhekeka;

4. Ukushintsha njalo, abasebenzi abaningi, izingxenye ezisele, kanye nezindleko zesikhathi sokungasebenzi.
