Isingeniso
Izimpawu zemishini zidlala indima ebalulekile ekuqinisekiseni ukusebenza kahle nokungavuzi kwamaphampu asolwandle. Lezi zingxenye zibalulekile ekugcineni ubuqotho bezinhlelo zoketshezi emikhunjini, izinkundla zasolwandle, nezinye izinhlelo zokusebenza zasolwandle. Uma kubhekwa izimo ezinzima zokuchayeka emanzini olwandle, izingcindezi eziphezulu, kanye nezindawo ezigqwalile, izimpawu zomshini kufanele ziqine, zithembeke, futhi zimelane nokugqokwa.
Lesi sihloko sihlola umsebenzi, izinhlobo, izinzuzo, nokugcinwa kwezimpawu zemishini kumaphampu asolwandle, ihlinzeka ngemininingwane ebalulekile yonjiniyela, abaqhubi bemikhumbi, nezingcweti zokunakekela.
Yini iziMechanical Seals?
Ama-mechanical seal angamadivayisi aklanywe ngokunemba aklanyelwe ukuvimbela ukuvuza koketshezi kumishini ezungezayo njengamaphampu nama-compressor. Ngokungafani nokupakishwa kwezindlala zendabuko, izimpawu zemishini zinikeza ukusebenza okuphezulu kokuvala, ukungqubuzana okuncishisiwe, nempilo ende yesevisi.
Kumaphampu asolwandle, izimpawu zemishini zibalulekile ku:
Ukuvimbela ukungena kwamanzi olwandle
Ukunciphisa isikhathi sokulungisa
Ukuthuthukisa ukusebenza kahle kwamandla
Ukuvikela izingxenye zephampu ekugqwaleni
Kungani Izimpawu Zemishini Zibalulekile Kumaphampu Asolwandle?
Amaphampu olwandle asebenza ngaphansi kwezimo ezimbi kakhulu, okuhlanganisa:
Usawoti omningi namanzi olwandle abolayo - Idinga izinto ezimelana nokugqwala njenge-silicon carbide, i-tungsten carbide, noma i-ceramic.
Izingcindezi eziguquguqukayo namazinga okushisa - Idinga izixazululo eziqinile zokuvala ukuze isingathe ukuguquguquka.
Ukusebenza okuqhubekayo - Kudinga izimpawu ezihlala isikhathi eside ukuze kuncishiswe ukwehluleka.
Ngaphandle kwezimpawu zemishini ezisebenzayo, amaphampu asolwandle angahlushwa yilokhu:
Ukuvuza kwe-fluid, okuholela ezingozini zemvelo kanye nokungasebenzi kahle kokusebenza.
Ukwenyuka kokuguga, ukunciphisa ubude besikhathi sephampu.
Izindleko zokunakekela eziphakeme ngenxa yokushintshwa njalo.
Izinhlobo Zezimpawu Zemishini Esetshenziswa Kumaphampu Asolwandle
Imiklamo eminingana yophawu lwemishini isetshenziswa ezinhlelweni zasolwandle, ngayinye ifanele izimo ezithile:
1. Single Mechanical Seals
