Izingozi Eziyinhloko Zokujiya Okweqile Kwamafutha

Emishinini yokupholisa njengama-compressor, ukujiya okuphezulu ngokweqile kwamafutha okugcoba akusho ukuthi "ukugcoba okubanzi"; esikhundleni salokho, kubangela izingozi eziningi ezithinta kabi ukusebenza kwemishini kanye nempilo yesevisi.

Okokuqala, kwandisa ukungqubuzana nokuguga kwezingxenye. Umsebenzi oyinhloko wamafutha ukwakha ifilimu emafutha elihlukene ukuhlukanisa izingxenye ezihambayo. Lapho i-viscosity iphakeme kakhulu, uketshezi lwefilimu yamafutha luyancipha, luhluleka ukugcwalisa ngokushesha izikhala ezincane ezingxenyeni. Lokhu kuholela ekuguqukeni kusuka ku-"friction yoketshezi" kuya ku-"semi-dry friction" noma kuze kube yi-"boundary friction", kwandisa kakhulu i-friction coefficient. Ngokuhamba kwesikhathi, izingxenye ezibalulekile ezifana nama-bearings, ama-pistons, nama-crankshafts azobhekana nokuguga okubangelwa ukungcola, ukuguga okubangelwa ukunamathela, okuholela ekulimaleni okungabuyiseki njengemikrwelo nokubambezeleka, kunciphisa kakhulu imijikelezo yokushintshwa kwawo.

Okwesibili, kwandisa ukusetshenziswa kwamandla kanye nezindleko zokusebenza. Ukuqina ngokweqile kwandisa ukungqubuzana kwangaphakathi kumafutha okugcoba. Ama-compressor kumele asebenzise amandla amaningi ukunqoba lokhu kuphikiswa, aqhubeke nokujikeleza kwamafutha kanye nokuhamba kwezingxenye. Lokhu kuholela ngqo ekwandeni kwamandla okungqubuzana, ukwanda komthwalo wemoto, kanye nokwanda okukhulu kokusetshenziswa kukagesi ngesikhathi esithile. Ezimishini zezimboni ezisebenza isikhathi eside njengezindawo zokugcina ezibandayo kanye nezinhlelo zokujikeleza komoya ezimaphakathi, ukuchithwa kwamandla okuhlanganisiwe kubangela ukulahleka okukhulu kwezomnotho.

Ngaphezu kwalokho, kwandisa ukumelana nokuqalisa kanye nezingozi zamaphutha. Ngesikhathi sokuqalisa, lapho amafutha okugcoba engagayi ukufudumala ngokugcwele, ukujiya okuphezulu kudala ukumelana okufana "ne-gel", kubangele ukwanda okukhulu ku-torque yokuqalisa. Lokhu kungaholela kalula ekulayisheni ngokweqile kwemoto, ukuphazamiseka, noma ukushiswa kwezintambo, futhi kungase futhi kubangele ukubambezeleka kwezingxenye, kulimaze izindlela zokuqalisa kanye nama-couplings.

Ngaphezu kwalokho, ukuminyana okuphezulu kunciphisa ukusebenza kahle kokudluliswa kokushisa, okuholela ekusebenzeni ngokushisa ngokweqile kwemishini. Lokhu kusheshisa ukuguga nokubola kwamafutha, kukhiqize udaka namabala ekhabhoni avimba imigudu kawoyela, kudale umjikelezo omubi. Kuyathinta nokusebenza kokuvala, kubangele ukuvuza kwamafutha kanye nama-refrigerant. Lokhu akugcini nje ngokuchitha amafutha kodwa futhi kuphazamisa ukulingana kwengcindezi yesistimu, kubeke izingozi zokuphepha.
