Umzekelo, amasuntswana abrasive kulwelo lwemizi-mveliso anokonakalisa isihlalo sevalve, okwenza kube lula ukuba i-debris iqokelele.
*Umhlwa kunye nokhukuliseko
Imiphezulu yentsimbi ebolileyo inokuvelisa amasuntswana axuba nolwelo, okwandisa ubuninzi benkunkuma ngaphakathi kwevalve. Ngokufanayo, ukhukuliseko olubangelwa yi-high-velocity fluids okanye i-abrasives lungonakalisa amacandelo angaphakathi e-valve, ukudala iindawo ezinqabileyo apho ukungcola kunokuhlala khona.
*Izenzo zogcino olungafanelekanga
Ukungakhathaleli ukucoca nokuhlolwa rhoqo kunokukhokelela ekuqokeleleni okungalawulekiyo kokungcola kunye nokungcola.
2.9.2 Izisombululo zokuthintela ukufumba kobutyobo
• Ukuhlolwa rhoqo kunye nokucocwa kwemibhobho kunye neevalvu
Abanini-zithuthi kufuneka bahlole rhoqo ukuvaleka, ukuguga okanye umonakalo owenziwe zizingcolisi. Ukongezelela, inkqubo kufuneka ihlanjululwe rhoqo ukususa ukungcola, i-rust kunye nezinye izinto ezingcolileyo. Kwimibhobho ephethe ulwelo oluqulethe izinto eziqinileyo ezinqunyanyisiweyo, ukufaka izikrini okanye izihluzi zokucoca phezulu kumjelo wevalve kunokunceda ukubamba inkunkuma phambi kokuba ifike kwivalve.
* Ukukhetha izinto eziphathekayo
Ukusebenzisa izinto ezichasene ne-corrosion ezifana nensimbi engenasici okanye i-alloys ekhethekileyo edibeneyo inokunciphisa ukuveliswa kweengqungquthela zangaphakathi. Ezi zixhobo zikwaxhathisa ngcono ulwelo olurhabaxa, luthintela ukhukuliseko kunye nokuqokelelana kobutyobo obulandelayo.
* Iindlela zokufakela ezifanelekileyo
Ukuhlola umbhobho wokungcola kunye ne-debris ngaphambi kokufaka i-valve kuthintela ukungcola ukungena kwinkqubo. Ukulungelelanisa ngokufanelekileyo ivalve kunye nokuyikhusela ngokukhuselekileyo kunciphisa izithuba apho i-debris inokuthi ihlale khona.
3. Isishwankathelo
Ukungaphumeleli kwevalve yebhabhathane kunye nezisombululo zazo zihlala zivela kwiingxaki ezinjengokuvuza, ukunxiba, ukubola kunye nokufakwa ngokungafanelekanga. Amanyathelo asebenzayo aqinisekisa ukusebenza ngokupheleleyo kunye nokunciphisa ukuphazamiseka. Ukugcinwa rhoqo, ukufakwa ngokufanelekileyo kunye nokukhethwa kwezinto ezihambelanayo kubalulekile ukwandisa ubomi be-valve. Ukubonisana nomboneleli wevalvu yebhabhathane oqeqeshiweyo kunye nokulandela imiyalelo kunokuphucula ukuthembeka kunye nokunciphisa ixesha lokuphumla.
