Njira yamphamvu idagwiritsidwa ntchito pofotokoza kugawa kodalira kukula kwa thovu la cavitation pamene kugwedeza kwamadzimadzi mu msonkhano wa valve wolamulira wokhala ndi cholekanitsa cha cylindrical ndi chipangizo chotseka gulugufe. Magawo omwe amakhudza kwambiri kugwedezeka kwa sing'anga yogwirira ntchito adasiyanitsidwa pakati pamitundu yambiri yamachitidwe. Kuwunika kwa mawonekedwe a stochastic a kusiyanasiyana kwa kukula kwa cavitation bubble mapangidwe, omwe adapeza potengera magawo odziwika bwino, adawonetsa kuti kusintha kuchokera pagawo loyambira la kugwedezeka kupita pakutsegula kwathunthu kwa valavu kumalumikizidwa ndi kuchepa kwa kuchuluka kwa ma valve. cavitation thovu ndi nthawi 1.06, malinga ngati kukula kwake kuchepetsedwa ndi nthawi 1.36.

Timatumikira makasitomala athu mwaulemu komanso mwaukadaulo.Pofuna kuchita bwino, timakhazikitsanso dongosolo loyendetsera bwino komanso kachitidwe.Timawonetsetsa kuti mafunso onse ayankhidwe munthawi yaifupi mokhutitsidwa, zogulitsa zonse ziziperekedwa mu chimango chomwe chafotokozedwa. nthawi.Mwambiri, sikuti timangopanga zinthu zathu zokha, komanso timapereka ntchito zonse zogulitsa pambuyo pogulitsa ndi yankho lathunthu.

Kodi jekeseni wa njanji wamba amasiyana bwanji ndi majekeseni ena ambiri?

Majekeseni a njanji wamba amagwiritsa ntchito njanji yothamanga kwambiri yomwe imapereka mafuta kwa majekeseni amodzi. Mosiyana ndi ma jekeseni a unit, njanji imasunga mafuta nthawi zonse, kuthamanga kwambiri komwe kuli kofunikira jekeseni. ... Kuthamanga kwapamwamba kumapangitsanso kuwonjezereka kwachangu komanso kupititsa patsogolo mpweya wabwino.
