Saldhigga korantada ee wiishashka Haydarooliga, waa nooc ka mid ah xarumaha haydarooliga ee yaryar iyo kuwa yar yar.Inta badan loo isticmaalo sidii unug koronto oo loogu talagalay wiishashka hawo-mareenka iyodhufto ee qaadista, waa ururinta matoorada, bambooyinka saliidda, baloogyada isku dhafan ee valve, blocks valves dibadda, valves hydraulic iyo qalabyada haydarooliga ee kala duwan (tusaale: accumulators).Marka la barbardhigo saldhigyada hydraulic-ga caadiga ah ee lagu gaaro shuruudaha mabda'a isku midka ah, waxay leedahay faa'iidooyinka qaabdhismeedka is haysta, mugga yar, miisaanka fudud, waxtarka sare, waxqabadka la isku halleyn karo, muuqaalka quruxda badan, wax daadsanaan ah iyo qiimo hoose.

Wiish Hydraulic ee la isticmaalo ayaa si lama filaan ah ula kulmi doona xaaladda gaarka ah ee awood la'aanta, haddii dhismaha la kulmo xaaladdan lama filaanka ah ha ka welwelin, qaybaha mashiinka iyo taangiga ku xiran waxay leeyihiin 2 nuts rotary, waxaa lagu gaari karaa iyada oo loo marayo kursiga bamka ee madax-bannaanida deg degga ah. valve hoos: marka ugu horeysa ee daboolka daboolka degdega ah hoos u rog, ka dibna isticmaal kaashawiito si tartiib ah oo ka soo horjeeda saacada ka soo horjeeda si aad u dejiso curiyaha hoos u dhiga, marka uu ku soo laabto meeshiisii ​​hore, ka dibna adkee furka soo degaya oo dabool daboolka line lowska ka dib.
