Usha Toosan/Usha Bistooladda ee Makiinada lagu farsameeyay
Hordhac Badeecada
JINYO waa soo-saare isku daraya cilmi-baarista iyo horumarinta, wax soo saarka, iibka iyo adeegga. Ganacsigeedu wuxuu daboolayaa qaybaha gudbinta haydarooliga, tuubooyinka birta saxda ah iyo qalabka injineernimada. Shirkaddu waxay isticmaashaa tignoolajiyada mashiinka shiididda iyo shiididda ee horumarsan, waxay leedahay awoodo wax soo saar iyo farsamayn gaar ah oo loogu talagalay usha chrome ee la habeeyey, bar chrome adag, usha piston-ka haydarooliga iyo tuubada silinda haydarooliga, tuubooyinka la shiiday, tuubada SRB, waxayna ka go'an tahay inay bixiso heerarka ugu sarreeya ee tayada iyo adeegga ugu fiican adduunka oo dhan.
Adeegyada la habeeyey
JINYO waxay leedahay farsamoyaqaanno wax soo saar xirfad leh iyo qalab wax soo saar oo horumarsan, waxayna habayn kartaa wax soo saarka ulaha chrome-plated iyo tuubooyinka la safeeyey iyadoo loo eegayo shuruudaha codsiga ee warshadaha kala duwan. Hadday tahay dhexroor gaar ah, dherer ama dhammaystir dusha sare ah, waxaan awoodnaa inaan bixinno ulo chrome-plated ah si loo daboolo baahiyaha nidaamkaaga haydarooliga.Usha bistoolada ee la farsameeyay oo loo habeeyey iyadoo la raacayo sawirrada macaamiisha: leexashada, godadka, gacanka gudaha/dibadda, dunta gudaha/dibadda, godadka axial/radial, godadka gudaha/dibadda ee shaabaddaha.
Marka laga soo tago habaynta ulaha chrome-plated, ulaha chrome-plated sidoo kale waxay leeyihiin cimri dherer aad u fiican. Dusha sare ee chrome-plated waxay hubisaa in is jiidjiid iyo xirasho yar la sameeyo, taasoo u oggolaanaysa dhululubada haydarooliga inay si habsami leh oo hufan u shaqeyso. Tani ma aha oo kaliya inay hagaajiso waxqabadka guud ee nidaamka, laakiin sidoo kale waxay yareysaa shuruudaha dayactirka, taasoo badbaadinaysa kharashyada iyo kordhinta wax soo saarka. Ulaha chrome-plated ayaa si weyn loogu isticmaalaa nidaamyada hydraulic-ga.

Tilmaamaha Badeecada
Usha Piston-ka badanaa waa bir qabow oo lagu duubay chrome-plated bir ah oo ku dheggan piston-ka oo ka soo baxda dhululubada ilaa madaxa usha. Dhululubada laba-geesoodka ah ee usha, hawl-wadeenku wuxuu leeyahay usha ka soo baxda labada dhinac ee piston-ka iyo labada daraf ee foosto.
Usha bistoonku waxay ku xidhaa hawl-wadeenka haydarooliga qaybta mashiinka ee shaqada qabanaysa. Xidhiidhkani wuxuu noqon karaa qaab dun mashiin ama qalab rakiban. Usha bistoonku aad ayay u burbursan tahay oo waa la safeeyey si loo helo shaabad lagu kalsoonaan karo oo looga hortago daadashada.
Ulaha Piston-ka waxay leeyihiin bir kaarboon ama bir aan miridh lahayn (goobaha daxalka leh). Ulaha Piston-ka badanaa waa la adkeeyaa ama waa la dahaadhaa. Hababka adag waxaa ka mid ah adkaanta kicinta.
Codsiyada:
Ushan usha ah ee wareegsan ee chrome-ka lagu dahaadhay ayaa ku habboon in loo isticmaalo codsiyo warshadeed oo kala duwan, oo ay ku jiraan mashiinnada wax soo saarka, mashiinnada daabacaadda, iyo qalabka kale ee farsamada.
