sharaxaad

Waalka tijaabada ah waa waalka kaaliyaha ah ee loo isticmaalo in lagu maamulo habka xakamaynta ee valves ama qaybaha kale.
Doorka nidaamka hydraulic waa in la kordhiyo xoogga adoo beddelaya cadaadiska. Nidaam biyo-dhaliye ah oo dhammaystiran wuxuu ka kooban yahay shan qaybood, kuwaas oo ah qaybaha awoodda, qaybaha fulinta, qaybaha xakamaynta, qaybaha kaalmada (alaabta) iyo saliidda. Nidaamyada Haydarooliga waxaa loo qaybin karaa laba qaybood: Nidaamyada wadista Haydarooliga iyo nidaamyada xakamaynta Haydarooliga. Shaqada ugu weyn ee nidaamka gudbinta hydraulic waa in la gudbiyo awoodda iyo dhaqdhaqaaqa. Nidaamka xakamaynta hydraulic wuxuu u baahan yahay inuu sameeyo wax soo saarka nidaamka hydraulic inuu buuxiyo shuruudaha waxqabadka gaarka ah (gaar ahaan waxqabadka firfircoon). Nadaamka hydraulic sida caadiga ah waxaa loola jeedaa habka gudbinta hydraulic.
Marka la tamarsiiyo, xoogga korantada ayaa furaya godka duuliyaha, cadaadiska qolka sare ayaa si degdeg ah u dhacaya, iyo cadaadis sare oo kala duwan ayaa lagu sameeyay agagaarka xubinta xiritaanka. Cadaadiska dareeraha ayaa riixaya xubinta xidhitaanka si uu kor ugu dhaqaaqo oo uu furmo; marka ay korontadu dansan tahay, xooga guga ayaa xira daloolka duuliyaha, Cadaadiska galitaanka wuxuu soo maraa godka la dhaafo, qolkuna wuxuu si deg deg ah u sameeyaa farqi hoose oo sarreeya oo ku wareegsan xubinta xiritaanka, iyo cadaadiska dareeraha ayaa riixaya xubinta xiritaanka si uu hoos ugu dhaqaaqo. si aad u xidho waalka.
Tilmaamaha guud:
1) Waxay samaysaa buundada dareeraha kontoroolka tijaabada ah oo leh iska caabin dareere go'an, waxayna koontaroolaysaa waalka weyn ama valve sare ama kabaalka doorsoomayaasha iyadoo loo eegayo calaamada gelinta.
2) Heerka socodka ee waalka duuliyaha heerka koowaad guud ahaan waa qiyaastii 1 litir/daqiiqo, ugu badnaana waa 3 litir/min. Heerka socodka ee waalka tijaabada labaad waa in lagu go'aamiyaa iyadoo loo eegayo baahiyaha dhabta ah.
3) Digniinta wax gelinta waa mid yar.
4) Waxay aqbali kartaa noocyo kala duwan oo hababka gelinta, sida buug-gacmeedka, koronto, hydraulic, pneumatic, kamarad farsamo, saamiga korantada, iwm.
5) Marka laga hadlayo xakamaynta bamka doorsooma, noocyo kala duwan oo ka mid ah valves pilot waxay sameeyaan qaab-dhismeed modular ah, taas oo sahlaysa in la doorto inta u dhaxaysa hawlo badan.
6) Qulqulka duuliyaha laftiisa ayaa badanaa ah waalka kantaroolka cabbirka yar, inta badanna waalka kantaroolka cadaadiska.
Mabda'a shaqada:
Marka la shaqeynayo, cadaadiska haydarooliga wuxuu ku shaqeeyaa cadaadiska cabbiraadda dusha sare ee dabaasha weyn iyo duuliyaha duuliyaha isku mar. Marka waalka duuliyaha aan la furin, saliiddu kuma socoto godka waalka, iyo cadaadiska ku shaqeeya spool weyn ee jihooyinka sare iyo hoose waa siman yihiin, laakiin sababtoo ah aagga cadaadiska waxtarka leh ee dusha sare ee sare ayaa ka weyn. Marka loo eego aagga cadaadiska wax ku oolka ah ee dusha sare ee hoose, qulqulka ugu weyn wuxuu ku jiraa xoogga natiijada hoosteeda ficilka, waxay ku jirtaa booska ugu hooseeya, iyo dekedda valve waa la xiray. Marka cadaadiska gelitaanka saliidda uu kordho si uu u furmo tuubada duuliyaha, dareeraha ayaa dib ugu soo qulqulaya taangiga isaga oo sii maraya cirifka sare ee dabaasha weyn iyo valve duuliyaha. Sababtoo ah saameynta qoyaanka ee orifice, cadaadiska hydraulic ee jihooyinka sare iyo hoose ee spool weyn maaha mid siman. Daboolka ugu weyn ayaa kor u kaca hoos ficilka farqiga cadaadiska si uu u furo dekedda valve si loo gaaro qulqulka iyo ilaalinta cadaadiska asal ahaan deggan. Cadaadiska qulqulka badan waxa lagu hagaajin karaa iyadoo la hagaajinayo cadaadiska hagaya guga duuliyaha.
