ukuthuthukiswa kwe-valve cast

Eminyakeni yamuva nje, imboni ye-pump capve cast yokwehla ngokushesha, kepha kusenezinkinga eziningi. Ngenxa yempi yentengo yesikhathi eside embonini yasekhaya yasekhaya kanye ne-valve, imboni yephampu ne-valve ibambeke endaweni ephakathi nendawo yemboni ye-valve yezwe isikhathi eside. Ngakho-ke, imboni yezwe lethu kanye ne-valve kumele iqale ngokushintsha imodi yokuncintisana futhi ishintshe isimo esibuthakathaka somkhakha we-pump kanye ne-valve.

Imboni ye-valve castve yase-China iye yathuthuka ngokushesha, kepha izinga lawo liphelele lisaphansi, okuqukethwe kwezobuchwepheshe boMkhiqizo wayo kuphansi, futhi ama-kelve asemqoka nawo ancike ekungenisweni. Izinga le-valve elikhona laseChina likhona okungenani iminyaka eyi-10 kuye kwangama-20 ngemuva kwawo emazweni athuthukile emhlabeni jikelele.

Kusekhona amaphutha amaningi ekuphathweni kwekhwalithi eChina. Okokuqala, inqubo inganakwa kakhulu noma incane kancane. Izinkampani eziningi zinohlelo lokuqinisekisa ikhwalithi, kepha azinandawo emsebenzini ongokoqobo. Ukuphathwa kwekhwalithi kwenziwa ngokwako, ngokungacabangi; Okwesibili inqubo yomhlangano. Futhi kuthambile. Akumangazi ukuthi amanye ama-valve avele avele agijima, egijima, edonsa noma evuza ngokushesha lapho efakiwe. Esinye isibonelo ukubuyela emuva kwemishini yokukhiqiza yasemabhizinisini amaningi, oye wahlala ezingeni lama-70s kuya ku-80s wekhulu leminyaka elidlule. Eminye imishini isivele idlulise impilo yenkonzo futhi isasebenza ngokugcwele. Ikhwalithi yokusebenza komkhiqizo ingaqinisekiswa kanjani? Ngezimali ezikhawulelwe, izikhungo ze-CNC kanye nemishini nazo zengezwe ngokulandelana. Kodwa-ke, inani lezinkampani ezakha imishini ye-CNC alizange libe likhulu embonini kuze kube manje, zibalwe ngamaphesenti angama-20 kuphela.
