Summarization
taxane JZH qalab Rotary set bamka vacuum waa la dhigay bamka Roots iyo bamka vacuum qalab Rotary. bamka vacuum qalab Rotary waxaa loo isticmaalaa sida bamka pre-vacuum iyo bamka vacuum taageero ah bamka xididdada vacuum ah. doorashada ee ratio barakaca ka dhexeeya bamka Roots vacuum ah, waxaa inta badan loo gudbiyaa bamka hoos dheer orodka dheer; marka shaqeeya vacuum yar yahay, waa advisedto dooro ratio barakac yar (2: 1 ilaa 4: 1); haddii shaqeeya vacuum dhexdhexaad ah ama sare, saamiga weyn barakaca (4: 1 10: 1) waa in la door bido.
Astaamaha
