Usha Bistooladda ee Silsiladda Haydarooliga ee Sare loo Habeeyey
Hordhac Badeecada
Xudunta ushayada bistoolada ee hydraulic-ga waa qaab-dhismeed bir ah oo tayo sare leh kaas oo mara habka dahaadhka chrome-ka adag ee adag. Hawshu waxay ku lug leedahay in lakabka chromium-ka lagu dhejiyo dusha sare ee usha, taasoo keenta dusha sare oo adag, siman oo aad u waara. Dahaadhka chrome-ka adag ma aha oo kaliya inuu kor u qaado bilicda usha, laakiin sidoo kale wuxuu bixiyaa ilaalin heer sare ah oo ka dhan ah xirashada, xoqidda iyo daxalka, taasoo hubinaysa cimri dheer xitaa jawiga ugu baahida badan.
Badeecadahayagu waxaa loogu talagalay inay buuxiyaan heerarka warshadaha ee tayada iyo isku halaynta. Ul kasta oo bistoolad ah waxay martaa tallaabooyin adag oo lagu xakameynayo tayada si loo hubiyo inay buuxiso heerarka ugu sarreeya ee saxnaanta iyo waxqabadka. Ballanqaadkan tayada iyo joogtaynta ayaa ka dhigaya badeecadaheena inay noqdaan doorasho lagu kalsoon yahay oo loogu talagalay codsiyada muhiimka ah halkaas oo isku hallayntu ay muhiim tahay.
Adeegyada la habeeyey
Mid ka mid ah astaamaha ugu muhiimsan ee ulaha piston-ka waa habayntooda. Waxaan fahamsanahay in codsiyada kala duwan ay u baahan yihiin cabbirro naqshadeed oo gaar ah, alaabtayaduna loo habeyn karo si ay u daboolaan shuruudaha gaarka ah ee macaamiisheenna. Hadday tahay dhexroor gaar ah, dherer ama dhammaystir dusha sare ah, waxaan awood u leenahay inaan bixinno xal gaar ah oo si fiican u daboolaya baahiyahaaga nidaamka haydarooliga.
Marka laga soo tago cimri dherer iyo habayn heer sare ah, ulaha piston-ka ee dhululubada haydarooliga waxaa loo sameeyay si ay u bixiyaan waxqabad wanaagsan. Dusha sare ee chrome-ka lagu dahaadhay 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 kor u qaaddo waxqabadka guud ee nidaamka laakiin waxay sidoo kale yareysaa shuruudaha dayactirka, taasoo keenta keydinta kharashka iyo kordhinta wax soo saarka.
Kala duwanaanta ulaha dhululubada haydarooliga ah ayaa ka dhigaysa kuwo ku habboon codsiyo warshadeed oo kala duwan, oo ay ku jiraan qalabka dhismaha, mashiinnada beeraha, nidaamyada maaraynta agabka iyo waxyaabo kaloo badan. Hadday tahay qaadis culus, riixid ama jiidid, alaabtayadu waxaa loo sameeyay inay bixiyaan waxqabad la isku halleyn karo oo joogto ah xaaladaha hawlgalka ee kala duwan.

Tilmaamaha Badeecada
Saxnaan sare: Usha chrome-ku waxay leedahay dhexroor sax ah iyo toosan si loo hubiyo in shaabaddu ay ku habboon tahay dhululubada haydarooliga ama sambabada.
Awood sare: Usha bistoonka waxaa laga sameeyay walxo xoog badan waxayna u adkeysan kartaa cadaadis iyo xiisad sare.
Iska caabbinta daxalka: Tiknoolajiyada daaweynta dusha sare ee chrome usha sida dahaadhka chrome, dahaadhka nickel, usha adag ee chrome plated, usha nickel chrome.
Iska caabinta xirashada: Adkaynta iyo nadiifinta usha chrome waxay hagaajinaysaa iska caabbinta xirashada usha piston-ka.
Habayn: Dhererka ul chrome, dhexroorka, agabka iyo daaweynta dusha sare waxaa loo habeyn karaa iyadoo loo eegayo baahiyaha kala duwan ee codsiga si loo daboolo xaaladaha shaqada ee gaarka ah iyo shuruudaha waxqabadka.
