Momwe mungasankhire pampu ya servo yothamanga kwambiri yamakina a hydraulic a mafakitale
Pampu yoyenera ya servo yokhala ndi mphamvu yapamwamba ndi yomwe imakwaniritsa mawonekedwe enieni a makinawo.
Makina oyendetsera ma hydraulic a mafakitale nthawi zambiri sagwira ntchito ndi mphamvu zonse tsiku lonse, ndichifukwa chake kusankha pampu yamafuta a servo kuyenera kuyamba ndi duty curve, osati nameplate rating. Pampu yomwe imatha kupereka 21 MPa nthawi yochepa ikhoza kukhala chisankho cholakwika ngati makinawo agwiritsa ntchito nthawi yake yambiri pamagetsi otsika ndipo akufunika kulamulira mphamvu zolimba. Pachifukwa ichi, mainjiniya ambiri amayesa phukusi lonse la servo: pampu, servo motor, drive, feedback, ndi oil circuit.
Malinga ndi machitidwe ofala a hydraulic, mphamvu ya kuthamanga kwa mpweya ndi gawo limodzi lokha la zomwe zafotokozedwa. Kukhazikika kwa kayendedwe ka madzi, kugwira ntchito bwino kwa voliyumu, komanso kutentha kumakhala kofunikira kwambiri makina akamayendetsa zinthu mobwerezabwereza.

Kupanikizika, kuyenda, kukhuthala, ndi nthawi yoyankhira ziyenera kuyesedwa pamodzi.
Pampu ya servo yothamanga kwambiri iyenera kuyang'aniridwa motsatira mfundo zisanu zothandiza: kuthamanga koyesedwa, kuthamanga kwambiri, kuchuluka kwa kusuntha, kulekerera kuyera kwa mafuta, ndi mayankho owongolera. Ngati ntchitoyo ndi makina ojambulira jakisoni kapena makina opangira, pampu ya mafuta ya servo iyenera kugwira kuthamanga popanda kusaka, chifukwa kuthamanga kosakhazikika kumasintha kukhala kung'anima, kusuntha kwa mawonekedwe, kapena mphamvu yolimba yosasinthasintha.

Mu mapulojekiti osinthira, ogwiritsa ntchito ambiri amayamba poyerekeza banja la mapampu lomwe lilipo kale ndi njira ina yogwirizana mu kapangidwe ka hydraulic komweko. Chitsanzo chothandiza ndikuwona ngati makinawo adamangidwa mozunguliraMndandanda wa ABT, aMndandanda wa T6, kapenaMndandanda wa VQnsanja, kenako ndikutsimikizira ngati pampu yatsopano ya servo hydraulic ingasunge momwe dera limayendera popanda kupanganso dongosolo lonse.
Kupanikizika, liwiro, ndi magwiridwe antchito a servo oil pump kukula
Liwiro ndi kupanikizika ziyenera kukhala zolinganizika, chifukwa malire ochulukirapo nthawi zambiri amawononga mphamvu.
Kukula kwa pampu ya Servo nthawi zambiri kumamveka molakwika ngati kuwerengera mphamvu ya akavalo, koma makina a hydraulic a mafakitale amafunikira mphamvu zoposa za injini. Chida chosankhidwacho chiyenera kugwira ntchito pa liwiro loyenera, ndi kusuntha kokwanira kuti chifike pa kuthamanga komwe mukufuna popanda kukakamiza injiniyo kuti ifike pamalo osagwira ntchito bwino. M'makina ambiri olamulidwa ndi servo, cholinga chake ndikuchepetsa kutayika kwa mphamvu ya throttling, ndichifukwa chake kuwongolera liwiro losinthasintha kumakhala kothandiza kwambiri kuposa kupompa liwiro lokhazikika pakugwira ntchito pang'ono kwa katundu.
Kuti muyezo ukhale wofanana, kuthamanga kuyenera kutsatiridwa mu MPa kapena bala, ndikuyenda mu L/min, pogwiritsa ntchito zida zoyezera. NIST ikuwona kufunika kwa kutsata muyeso m'mafakitale, ndipo izi ndizofunikira poyerekeza mapepala azidziwitso a ogulitsa. Pampu yolengezedwa kuti ndi "kuthamanga kwakukulu" imakhala ndi tanthauzo pokhapokha ngati kuthamanga, kuyenda, ndi ntchito zonse zafotokozedwa pansi pa mikhalidwe yofanana yoyesera.

Kusintha kwa pampu ya hydraulic ya Servo kwa makina akale a Vickers, Denison, Yuken, Tokimec, ndi Rexroth
Kugwirizana nthawi zambiri ndiye chinthu chofunikira kwambiri pa ntchito yosintha.
Pokonza mafakitale, ogula nthawi zambiri amayamba pa zero. Nthawi zambiri amafunikira servo pump yomwe ingalowe m'malo mwa OEM yakale popanda nthawi yayitali yogwira ntchito, makina obisika, kapena kusintha kwa kuwongolera. Ichi ndichifukwa chake kugwirizanitsa kwa mndandanda ndikofunikira. Chofunikira kwambiri pakukonzanso sikusintha kwamalingaliro koma kothandiza: kusunga makinawo kukhala ogwira ntchito bwino pamene akukonza magwiridwe antchito, phokoso, ndi mayankho.
Pazida zakale, kufanana kwa katalogu kuyenera kuwonedwa m'magawo atatu: magwiridwe antchito a hydraulic, mawonekedwe a makina, ndi kuphatikiza kowongolera. Pampu yamafuta a servo ikhoza kukhala yapamwamba kwambiri koma ikalephera kugwira ntchito ngati kiyi wa shaft, flange, mawonekedwe a port, kapena mawonekedwe a waya ndi olakwika. Pantchito yosintha, ndi pomwe matrix yokonzedwa bwino imakhala yamtengo wapatali.
- Tsimikizani mndandanda woyambirira ndi kukula kwa chimango musanasankhe cholowa m'malo.
- Kutengera machesi, kuzungulira, mtundu wa shaft, ndi nkhope yoyikira.
- Tsimikizani momwe kuthamanga kwa magazi kumakhalira, njira yochepetsera kuthamanga kwa magazi, komanso nthawi yogwirira ntchito.

- Sungani zida zosinthira ndi zomata zogwirizana ndi mapulani okonzera.
Cholinga chake chikakhala kutumiza mwachangu komanso chithandizo chakale, ogula nthawi zambiri amayerekezera mabanja angapo azinthu nthawi imodzi, kuphatikizapoMndandanda wa Vnjira yopitirizira dongosolo ndiMndandanda wa V10njira yopezera malo ambiri oti alowe m'malo.
Momwe miyezo ya ISO ndi ukhondo wamadzimadzi zimakhudzira moyo wa pampu ya servo yothamanga kwambiri
Mafuta oyera ndi chimodzi mwa zinthu zomwe zimasonyeza kudalirika kwa pampu ya servo.
Machitidwe a servo ndi osavuta kuipitsa chifukwa malo otseguka bwino komanso malo olumikizirana mwachangu salola kuti tinthu tating'onoting'ono tiwonongeke.ISO 4406amagwiritsidwa ntchito kwambiri pofotokoza kuchuluka kwa kuipitsidwa kwa madzi a hydraulic, ndipo kuwongolera bwino kuipitsidwa kumathandiza mwachindunji kukhala ndi moyo wautali wa zigawo. Kwa ogula, izi zikutanthauza kuti kusefa ndi gawo la kusankha pampu, osati kuganizira zamtsogolo.
M'machitidwe, kulamulira kuipitsidwa kuyenera kufotokozedwa pamodzi ndi pampu. Ngati makinawo akugwira ntchito pamalo ovuta kapena ovuta kwambiri, chiŵerengero cha beta cha fyuluta, kupuma kwa reservoir, ndi nthawi yosamalira zingakhale zofunika monga momwe pampuyo imagwirira ntchito. Kwa magulu a m'munda, mafuta okhazikika amachepetsa kuwonongeka kwa makatiriji, kuthamanga kwa mpweya, komanso nthawi yopuma.
| Chinthu cha ukhondo | Chifukwa chake ndikofunikira | Chidziwitso chosankha |
|---|---|---|
| Kuipitsidwa ndi tinthu tating'onoting'ono | Imathandizira kuwonongeka kwa pampu ndi ma valve | Tchulani kusefera pamlingo wa dongosolo |

| Kukhazikika kwa kukhuthala | Kusintha kutayikira ndi kuyankha | Gwirizanitsani mafuta ndi kutentha kwa ntchito |
| Kulamulira kutentha | Zimateteza zitseko ndikuwongolera magwiridwe antchito | Gwiritsani ntchito kuziziritsa pamene ntchito yozungulira ili yokwera kwambiri |
Ndondomeko ya kuyeretsa madzi ya International Organization for Standardization ndi yothandiza kwambiri pamene wogula akufuna deta yofanana ya ogulitsa m'malo mwa mawu osamveka bwino a "ubwino wapamwamba". Pa pampu ya hydraulic ya servo yomwe imagwiritsidwa ntchito mu makina osindikizira kapena oumba, kutsata kumeneko kumathandizira kukonzekera kukonza ndikuthandiza wogula kuyerekeza njira zina zosinthira moyenera.
Kuthekera kosunga mphamvu m'makina opopera madzi a hydraulic m'mafakitale
Makina osinthira katundu ndi komwe ukadaulo wa servo ungapereke phindu lomveka bwino.
Makina a hydraulic oyendetsedwa ndi servo nthawi zambiri amagwiritsidwa ntchito kuchepetsa kutayika kwa mphamvu m'makina omwe amagwiritsa ntchito gawo lalikulu la kayendedwe kawo pansi pa katundu wolemera kwambiri. M'mabwalo ambiri okhazikika a liwiro lokhazikika, mphamvu imatayika kudzera mu throttling, bypass flow, kapena ntchito yopitilira ya liwiro lonse. Pampu ya servo yogwirizana bwino imachepetsa zinyalalazo popereka kayendedwe kokha kofunikira pa gawo lililonse la kayendedwe kake.
Mu gawo la kupanga makina opangira jakisoni, kusunga mphamvu nthawi zambiri kumakhala chinthu chachikulu chomwe chimayambitsa kugula, makamaka makina akale akale akamakonzedwanso. Malinga ndi zokambirana zamakampani ndi zokonzanso, phindu limadalira mbiri ya njinga, kukula kwa makina, ndi maola ogwirira ntchito, kotero ogula ayenera kufunsa deta yoyezedwa ya mphamvu yoyambira ndi pambuyo pa kukweza m'malo mwa malonjezo. Wogulitsa wodalirika ayenera kukhala wokhoza kuwonetsa mawerengedwe a kW asanafike komanso atatha kugwiritsa ntchito pansi pa mayeso omwewo.
Kwa magulu ogula zinthu, chofunika kwambiri si kungogwiritsa ntchito mphamvu zochepa komanso kuchepetsa kutentha. Kutentha kochepa kumachepetsa kukalamba kwa mafuta, kupsinjika kwa seal, komanso kufunikira koziziritsa. M'mafakitale ambiri, izi zimapangitsa kuti pakhale phindu lachiwiri: kukhazikika bwino kwa ntchito panthawi yopangira zinthu kwa nthawi yayitali.
Tebulo loyerekeza la pampu ya servo yothamanga kwambiri kwa ogula othandiza
Chosankha chabwino kwambiri cha pampu ndi chomwe chikugwirizana ndi makina anu, mafuta anu, ndi gulu lanu lokonza.
