Ingcaciso yeMveliso
Ngoyilo lwe-double offset, idiski isuka kwisihlalo ngokukhawuleza xa ivulwa. Oku kunceda ukunciphisa ukungqubana kumphezulu wokutywina. Xa ivala, idiski icinezela kwisihlalo esiqinileyo ukuze ifezekise ukutywina ngokuguquguquka okuncinci. Ngokwenyani, olu yilo luhlala ixesha elide kuneevalvu zebhabhathane ezixineneyo kwaye ludla ngokufuna i-torque encinci yokusebenza.
Izinto zesihlalo zingaba yi-EPDM okanye i-VITON, kuxhomekeke kwindlela yokusebenza. Kumanzi acocekileyo, amanzi amdaka, okanye ulwelo olune-corrosive kancinci, olu hlobo lwesitywino esithambileyo ngokubanzi lwanele. Kumaqondo obushushu aphezulu okanye kwiindawo ezishushu ngakumbi, uyilo lwesihlalo sentsimbi ludla ngokuqwalaselwa endaweni yoko.
Izinto zomzimba kunye neediski zinokukhethwa ngokusekelwe kwiimfuno zeprojekthi. Iindlela eziqhelekileyo ziquka intsimbi ethambileyo, intsimbi yekhabhoni, kunye nentsimbi engatyiwayo. Isiqu senziwe ngentsimbi engatyiwayo okanye eshushu ukuqinisekisa amandla asisiseko kunye nokumelana nokuguguleka.
Ukuphatha nokufakela, umzimba wevalvu wenzelwe iinyawo ezixhasayo kunye nee-ligs zokuphakamisa. Oku kuluncedo ngakumbi kwiisayizi ezinkulu. Uqhagamshelo oludibeneyo luqhelekile kwaye luhambelana neenkqubo ezininzi zepayipi.
