Gariirada fiilada fiilada ee dareeraha ah

HVD waa isticmaalka tignoolajiyada gudbinta viscous dareere ah sida duudduuban slipmechanism ah qalabka dabaylaha cable, technology xudunta u been in ay unugga shaqada silbasho dareereviscosity.HINAR ayaa awooday in ay hagaajiso dhexdhexaadinta HVD la xiriira saliidda, cadaadis gaar ah, heerkulka, viscosity iyo qaabka, cabbirka, jeexdin, iyo jeexdin filimka saliidda ee HVD.Muddo dheer ka dib cusboonaysiinta iyo tijaabinta, Qalabka iyo arrimo kale si loo hubiyo in HVDin xaaladaha kala duwan hoos xasilloon oo la isku halayn karo.
