12Cr1MoVG uxinzelelo oluphezulu lwentsimbi yombhobho wokuqinisekisa umgangatho

Ngenxa yeenkqubo ezahlukeneyo zokuvelisa, yahlulwe yaba ngumbhobho wentsimbi eshushu oqengqelekayo (okhutshiweyo) kunye nombhobho wentsimbi ongenamthungo otsalweyo (oqengqiwe). Umbhobho obandayo (oqengqiwe) wahlulwe waba ngumbhobho ojikelezayo kunye nombhobho okhethekileyo.

a. Isishwankathelo senkqubo

Umbhobho wentsimbi oshushu oqengqelekayo (okhutshiweyo) ongenamthungo: ityhubhu engqukuva engenanto → ukufudumeza → ukugqobhoza → ukuqengqeleka okuthathu okuqengqelekayo, ukuqengqeleka okuqhubekayo okanye ukukhutshwa kombhobho → ukuhluba umbhobho → ukulinganisa (okanye ukucutha) → ukupholisa → ityhubhu engenanto → ukulungisa → uvavanyo lwe-hydrostatic (okanye ukubonwa kwentsilelo) → ukuphawula → ugcino.

Umbhobho wentsimbi obandayo (uqengqelekiyo) ongenamthungo: ityhubhu engqukuva engenanto → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuchola → ukuthambisa (iplanga yobhedu) → imizobo emininzi ebandayo (ukuqengqeleka okubandayo) → ityhubhu engenanto → unyango lobushushu → ukulungisa → uvavanyo lwe-hydrostatic (isiphene ubhaqo) → ukuphawula → ugcino.
