Uvavanyo lwenzuzo yeendleko: Uhlalutyo lwezoqoqosho lwemigangatho ye-American cast iron globe valves ekusebenzeni kwexesha elide
Kwiinkqubo zokulawula ulwelo, iivalvu zeglowubhu yentsimbi esemgangathweni yaseMelika zithandwa ngokubanzi ngokusebenza kwazo okugqwesileyo kunye nokuqina. Nangona kunjalo, kumashishini amaninzi, ukongeza ekusebenzeni kwemveliso, ukuphumelela kweendleko ekusebenzeni kwexesha elide kukwayinto ebalulekileyo ekufuneka uyiqwalasele xa ukhetha iintlobo zevalve. Eli nqaku liza kuqhuba uhlalutyo olunzulu lokusebenza koqoqosho lwe-American standard cast iron globe valves ekusebenzeni kwexesha elide ukuvavanya ukusebenza kwazo kweendleko.
1, Uhlalutyo lweendleko zotyalo-mali lokuqala
Iindleko zokuqala zotyalo-mali zomgangatho we-American cast cast iron globe valves zihlala ziphezulu, ikakhulu ngenxa yezixhobo ezikumgangatho ophezulu, iinkqubo ezichanekileyo zokwenziwa, kunye nolawulo olungqongqo lomgangatho. Nangona kunjalo, eli xabiso liphezulu lotyalo-mali lokuqala linokuvelisa imbuyekezo ukusuka kwixesha elide kunye nozinzo. Xa kuthelekiswa nezinye iimveliso zevalvu ephantsi, nangona utyalo-mali lokuqala lwe-American standard cast iron globe valves luphezulu ngokwentelekiso, ukusebenza kwabo ekusebenzeni kwexesha elide kudla ngokuba ngcono, okunokunciphisa ngempumelelo iindleko zokugcinwa kunye nokutshintshwa kwamatyeli kwinqanaba lamva.
2, Uhlalutyo lweendleko zokusebenza kunye nokugcinwa
Iindleko zokugcinwa kweevalvu zeglobhu yentsimbi esemgangathweni yaseMelika ngexesha lokusebenza ziphantsi. Ngenxa yesakhiwo sayo esomeleleyo, ukusebenza kakuhle kokutywina, kunye nokunganyangeki okuqinileyo kwe-corrosion, kunokunciphisa inani lokulungiswa okubangelwa ukuvuza okanye umonakalo. Ukongeza, ivalve yeglowubhu yentsimbi esemgangathweni yaseMelika kulula ukuyisebenzisa kunye nokugcina, ukunciphisa iindleko zokugcina. Kumsebenzi wexesha elide, olu phawu lwexabiso eliphantsi lolondolozo lunokugcina uninzi lwabantu kunye nezinto eziphathekayo kumashishini.
I-3, Uhlalutyo lokuSebenza koMbane kunye nokuGcinwa kwamandla kunye nokuNcitshiswa koMbane
Ivalve yeglowubhu yentsimbi esemgangathweni yaseMelika nayo isebenza kakuhle ngokubhekiselele ekusebenzeni kakuhle kwamandla kunye nokugcinwa kwamandla kunye nokunciphisa ukukhutshwa. Ngenxa yokusebenza kwayo kakuhle kokutywina kunye nolawulo oluchanekileyo lokuhamba, inokunciphisa ukuvuza kwamanzi kunye nenkunkuma kwinkqubo, ngaloo ndlela iphucula ukusebenza kakuhle kwamandla. Ukongeza, imathiriyeli kunye noyilo lweevalvu zeglowubhu zentsimbi ezisemgangathweni zaseMelika nazo ziyahlangabezana neemfuno zokusingqongileyo, ezinceda amashishini afezekise ugcino lwamandla kunye neenjongo zokunciphisa ukukhutshwa kokusebenza kwexesha elide.
4. Uvandlakanyo olubanzi lwenzuzo
Ngokusekelwe kolu hlalutyo lungentla, nangona iindleko zokuqala zotyalo-mali zomgangatho we-American standard cast iron globe valves ziphezulu kakhulu, iindleko zabo zokugcinwa okuphantsi, ukusebenza kakuhle kwamandla, kunye nokusebenza kokusingqongileyo kuphucula kakhulu ukuphumelela kwazo zonke kwiindleko ekusebenzeni kwexesha elide. Ngokunciphisa ukugcinwa rhoqo, ukusetyenziswa kwamandla, kunye nokukhutshwa kongcoliseko, amashishini anokonga iindleko ezininzi kwaye aphucule ukusebenza kakuhle kwemveliso. Ukongeza, uzinzo kunye nokuthembeka kweevalvu zeglobhu zentsimbi zaseMelika zikwanciphisa umngcipheko wokuphazamiseka kwemveliso okubangelwa kukungaphumeleli kwevalvu kumashishini, ngakumbi ukuphucula izibonelelo zabo zoqoqosho.
Ke ngoko, ekuhambeni kwexesha, ukukhetha iivalvu zeglowubhu zentsimbi zaseMelika sisigqibo esinexabiso eliphantsi. Xa ukhetha iimveliso zevalve, amashishini kufuneka aqwalasele ngokubanzi izinto ezifana nokusebenza kwemveliso, iindleko zotyalo-mali lokuqala, iindleko zokulondolozwa kwexesha elide, ukusebenza kakuhle kwamandla, kunye nokusebenza kokusingqongileyo ukuze kuphunyezwe eyona ndleko isebenzayo.
Kufuneka kuqatshelwe ukuba iimeko ezahlukeneyo zesicelo kunye neemeko zokusebenza zinokuba nefuthe elithile kuqoqosho lwe-American standard cast iron globe valves. Ke ngoko, kwizicelo ezisebenzayo, amashishini kufuneka akhethe kwaye avavanye ngokweemeko ezithile ukuqinisekisa ukuba iimveliso ezikhethiweyo zevalve zinokuhlangabezana neemfuno zazo zokwenyani kwaye zizise inzuzo enkulu yezoqoqosho.
