Yini ebangela i-over-pressurization?
Umfutho kawoyela wenjini owedlulele uwumphumela wevalvu elawula umfutho kawoyela engalungile.Ukuze uhlukanise kahle izingxenye zenjini futhi uvimbele ukuguga ngokweqile, uwoyela kufanele ube ngaphansi kwengcindezi.Iphampu inikeza uwoyela ngamavolumu kanye nezingcindezi ezinkulu kunalokho okudingwa yisistimu ukugcoba ama-bearings nezinye izingxenye ezihambayo.I-valve yokulawula iyavuleka ukuvumela ivolumu eyengeziwe kanye nokucindezela ukuba kuphambukiswe.
Kunezindlela ezimbili ivalvu ehluleka ngayo ukusebenza ngendlela efanele: noma inamathela endaweni evaliwe, noma iyephuza ukuya endaweni evulekile ngemva kokuba injini isiqalile.Ngeshwa, i-valve enamathele ingazikhulula ngemva kokwehluleka kwesihlungi, ingashiyi ubufakazi banoma yikuphi ukungasebenzi kahle.
Qaphela: Umfutho kawoyela owedlulele uzodala ukonakala kwesihlungi.Uma i-valve elawulayo isalokhu ibambekile, i-gasket phakathi kwesihlungi nesisekelo singaphuma noma i-seam yokuhlunga izovuleka.Uhlelo luzolahlekelwa yiwo wonke uwoyela walo.Ukunciphisa ubungozi bohlelo olunomfutho owedlulele, abashayeli bezimoto kufanele belulekwe ukuthi bashintshe uwoyela nesihlungi njalo.
Ayini ama-valve ohlelweni lukawoyela?
1. I-Oil Pressure Regulating Valve
2. I-Relief (Bypass) Valve
3. I-Anti-Drainback Valve
4. I-Anti-Siphon Valve
Zihlolwa Kanjani Izihlungi?
1. Izilinganiso Zobunjiniyela Besihlungi.Ukusebenza kahle kokulinganisa kufanele kusekelwe esimisweni sokuthi isisefo sikhona enjinini ukuze sikhiphe izinhlayiya eziyingozi futhi ngaleyo ndlela sivikele injini ekuguge.
2. Ikhono Lokuhlunga likalwa esivivinyweni esicaciswe ku-SAE HS806.Ukuze udale isihlungi esiyimpumelelo, kufanele kutholakale ibhalansi phakathi kokusebenza kahle okuphezulu nempilo ende.
3. Ukuphumelela Okukhulayo kukalwa phakathi nokuhlolwa komthamo wesihlungi okwenziwa ku-SAE ejwayelekile HS806.Ukuhlola kwenziwa ngokwengeza ngokuqhubekayo ukungcola kokuhlola (uthuli) kuwoyela ojikeleza ngesihlungi.
4. I-Multipass Efficiency.Le nqubo isanda kuthuthukiswa kulezi zintathu futhi iqhutshwa njengenqubo enconyiwe yizinhlangano zamazwe ngamazwe kanye nezase-US.Kubandakanya ukuhlolwa okusha
5. Ukuhlolwa kweMechanical kanye Nokuqina.Izihlungi zikawoyela nazo zingaphansi kokuhlolwa okuningi ukuze kuqinisekiswe ubuqotho besihlungi kanye nezingxenye zaso phakathi nezimo zokusebenza kwemoto.
6. I-Single Pass Efficiency ikalwa esivivinyweni esicaciswe yi-SAE HS806.Kulesi sivivinyo isihlungi sithola ithuba elilodwa kuphela lokususa ukungcola emafutheni
