Ukuhlola Amapayipi Amelana Ne-Silicon Carbide Wear: Umnakekeli “we-Hardcore” Wezokuthutha Zezimboni

Ezimeni zemihlangano yokusebenzela yasefekthri, izimayini, noma ukudluliswa kwamandla, kunohlobo lwepayipi “okungaziwa” unyaka wonke kodwa elithwala imithwalo yemfanelo esindayo - ngokuvamile lithutha imidiya enezinto ezinamandla zokuhuzuka njengesihlabathi, udaka, impushana yamalahle, njll. Amapayipi avamile angase agqokwe ngesikhathi esifushane, angagcini nje ngokuthinta ukusebenza kahle komkhiqizo kodwa futhi abangele ubungozi bokuphepha. Ukuvela kweamapayipi we-silicon carbide angagugiiwukuxazulula le nkinga yezimboni, ibe umnakekeli “oqinile” ezindaweni zokuthutha ezinokhahlo.
Liyini ipayipi elimelana ne-silicon carbide?
Kalula nje, amapayipi amelana ne-silicon carbide angamapayipi okuthutha enziwe ngokuhlanganisa i-silicon carbide njengento ewumgogodla engagugi namapayipi ensimbi (njengamapayipi ensimbi) ngezinqubo ezikhethekile.
Omunye angabuza, iyini i-silicon carbide? Iwumsebenzi owenziwe ngokwenziwa we-inorganic non-metallic enobulukhuni obuphakeme kakhulu, okwesibili ngemuva kwedayimane. Ama-sandpaper amaningi namasondo okugaya esiwabona ekuphileni kwansuku zonke enziwe nge-silicon carbide. Ukusebenzisa 'uchwepheshe ongagugi' onjalo ukwenza ulayini lwangaphakathi lwamapayipi ngokwemvelo kungabanikeza ukumelana nokugqokwa okuqine kakhulu.

Uma kuqhathaniswa namapayipi ensimbi evamile evamile kanye namapayipi amatshe asakazwayo, inzuzo eyinhloko yamapayipi we-silicon carbide angagugi ilele "kokukhanda kokubili kwangaphakathi nangaphandle": ungqimba lwangaphakathi lwe-silicon carbide lunesibopho sokumelana nokuguguleka nokuguga kwendawo ephakathi, kuyilapho ungqimba lwensimbi lwangaphandle luqinisekisa amandla aphelele namandla okucindezela epayipi. Ukuhlanganiswa kokubili akuxazululi kuphela inkinga yokumelana nokugqoka, kodwa futhi kucabangela ukuphepha nokuthembeka kokusetshenziswa kwezimboni.
Kungani 'ingakwazi ukumelana' nezindawo ezinokhahlo?
Ukuqina kwamapayipi we-silicon carbide ukumelana nokugqoka ikakhulukazi kuvela ezicini ze-silicon carbide material uqobo:
Ukumelana nokugqoka okuqinile okuqinile: Njengoba kushiwo ngaphambili, i-silicon carbide inobulukhuni obuphakeme kakhulu, futhi ukugqokwa kwayo okungaphezulu kuhamba kancane lapho ibhekene nokuguguleka okuhlala isikhathi eside okuvela emithonjeni ye-granular efana ne-slurry nesihlabathi. Uma kuqhathaniswa namapayipi ensimbi avamile, impilo yabo yesevisi ingavame ukunwetshwa izikhathi eziningana noma ngisho nangaphezu kwezikhathi eziyishumi, ukunciphisa kakhulu imvamisa kanye nezindleko zokushintshwa kwamapayipi.
Ukumelana nezinga lokushisa eliphezulu neliphansi kanye nokumelana nokugqwala: Ngaphezu kokumelana nokugqokwa, i-silicon carbide ingakwazi futhi ukuzivumelanisa nezinga lokushisa elibanzi, futhi ingasebenza ngokuzinza ezindaweni ezisukela kumashumi amancane amadigri Celsius kuya kumakhulu amadigri Celsius. Ngesikhathi esifanayo, iphinde ibe nokuphikiswa okuhle emithonjeni ebolayo efana ne-asidi ne-alkali, okwenza "ikwazi" ezimweni zokuthutha eziyinkimbinkimbi ezimbonini ezifana namakhemikhali kanye ne-metallurgical.
Ukusebenza kahle kokudlulisa okuzinzile: Ngenxa yobuso obushelelezi be-silicon carbide lining, ukumelana nendawo egeleza epayipini kuphansi, kuyenza ingavaleki. Lokhu akuqinisekisi ukusebenza kahle kwezokuthutha kuphela, kodwa futhi kunciphisa isikhathi sokuphumula esibangelwa ukuhlanzwa kwamapayipi.
Iwakhombisa kuphi amakhono ayo?
Nakuba kuzwakala “njengochwepheshe”, ukusetshenziswa kwamapayipi angagugi we-silicon carbide empeleni kuseduze kakhulu nokukhiqizwa nokuphila kwethu:
Ezimbonini zezimayini nezensimbi, isetshenziselwa ukuthutha udaka lwamaminerali olusuka ezimayini kanye nensalela yemfucuza ekuncibilikisweni, futhi ibhekana nokuguga okukhulu nokudabukile okuvela kumithombo yezindaba egxilile kakhulu;
Embonini yamandla, kuyipayipi elibalulekile lokuthutha impushana yamalahle ezimbonini zamandla ashisayo, ukuqinisekisa ukutholakala okuzinzile kwe-boiler fuel;
Ezimbonini zokwakha kanye nezimboni zamakhemikhali, ingakwazi ukuthutha izinto zokusetshenziswa zikasimende, izinto zokusetshenziswa zamakhemikhali, njll., ukuze ibhekane nokuguga kanye nokugqwala okuncane kwemidiya ehlukene.
Kungashiwo ukuthi kunoma iyiphi insimu yezimboni edinga ukuthuthwa kwemidiya enokumelana nokugqoka okuqinile kanye nezimo zokusebenza eziyinkimbinkimbi, ukuba khona kwamapayipi aphikisana ne-silicon carbide angabonakala. Ihlinzeka ngeziqinisekiso ezibalulekile zokuqhubeka nokusebenza ngempumelelo kokukhiqizwa kwezimboni ngokusebenza kwayo "okuqinile", futhi isibe yingxenye ebalulekile yezinhlelo zesimanje zokuthutha ezimbonini.
