Makina opangira ma hydraulic transmission system muzinthu zazikulu monga chosinthira cha gearbox torque (chomwe chimatchedwa kusintha kawiri) ndi gawo lantchito yama hydraulic system munjira zambiri zosinthira valavu ndi O-ring ndi zisindikizo zina, ambiri aiwo akhala akugwiritsidwa ntchito mphira wa fluorine (FKM) kusindikiza zinthuzo ali ndi kukana kwamafuta abwino, kukana kwa abrasion ndi kupewa kukana, kukana kutentha kwadongosolo, kuwongolera kutentha kwadongosolo ndi kukana kutentha. durability wakwaniritsa zinazake. Komabe, chifukwa cha kukhalapo kwa zisindikizo zotere, mtengo wapamwamba, kukana kosauka kwa rancidity kuwonongeka kwa mafuta, kukana kuzizira ndi zinthu zina zoipa, zomwe zimapangitsa kuti mtengo wa mankhwalawo ukhale wochuluka, komanso umakhudza malonda a malonda, choncho m'pofunika kupeza chuma chosindikizira chokhazikika komanso chokhazikika m'malo mwa zinthu zomwe zilipo.
HNBR ndi Katundu Wake
HNBR ndi mtundu watsopano wa elastomer wosamva mafuta womwe unayambitsidwa ndi Nippon Zeon mu 1984, yomwe idapangidwa kuti ikwaniritse kufunikira kwachangu kwa zopangira mphira pansi pazovuta zamagalimoto zamagalimoto. Ndibwino kwambiri kukana kwamafuta a rabara ya nitrile (code name NBR) mamolekyu a carbon-carbon double bond kusankha hydrogenated (saturated) processing of the molecular structure, kusintha kutentha kwa NBR, maroon chemical bata ya kufooka kwa osauka, ndi mphamvu zabwino kwambiri ndi kukana kutentha kwakukulu ndi kutsika, kukana mafuta ndi mankhwala opangira mankhwala, monga kukana ndi kuchita bwino kwambiri. Nthawi yomweyo amasunga kukana kwabwino kovala komanso kusinthika kwa NBR. Poyerekeza ndi FKM ndi NBR
Makhalidwe akuluakulu a HNBR ndi awa:
(1) Kutentha kusinthasintha: HNBR angagwiritsidwe ntchito kwa nthawi yaitali pa l50 ℃ , ntchito yochepa kutentha kwa l75 ℃.
HNBR, angagwiritsidwe ntchito kwa nthawi yaitali pa 230 ℃ , ntchito yochepa kutentha kwa 300 ℃ . HNBR kutentha kukana pakati pa NBR ndi FKM, koma mawu otsika kutentha kukana, FKM ozizira kukana ndi osauka (-15 ℃ kuti n'zosavuta Chimaona fracture); ndipo HNBR ili ndi magwiridwe antchito otsika kwambiri, okhala ndi malire abwino pakati pa kukana mafuta
(2) Thupi ndi makina katundu: ambiri mafuta zosagwira mphira chifukwa otsika amakokedwe mphamvu, choncho malire kukula kwa ntchito yake, monga FKM kumakoka mphamvu ya 19.6-21.6MPa, HNBR mphamvu kuposa NBR, ACMXNBR, EPDM ndi FKM ndi mitundu ina ya mphira ndi apamwamba, monga hydrogendi mphira mphira ZSC koma mphira wa hydrogen nitrole Zeon ZSC 6OMPa chofunika kwambiri, ndi HNBR pa kutentha kwambiri (Chofunika kwambiri, HNBR pa kutentha kwambiri (15O ℃ ) pansi pa mphamvu (14.7-29.4MPa) ndi chipinda kutentha NBR kukhalabe mlingo womwewo pa kutentha mu zosiyanasiyana mafuta zovuta ndi mankhwala TV akhoza kukhalabe zabwino makina katundu, kutentha thupi ndi makina katundu ndi bwino kukana zotanuka kwambiri kuposa mabrasion matching thupi.
Kuphatikiza kwaukadaulo, mutha kupeza mawonekedwe abwino kwambiri otenthetsera kutentha kwambiri, ndipo magwiridwe antchito a FKM si abwino.
(3) mankhwala TV kukana: HNBR ali kwambiri kukana mafuta pa kutentha kwambiri, kukana zosiyanasiyana lubricant mafuta hayidiroliki, mafuta mafuta munali zosiyanasiyana zina, amphamvu zikuwononga oxidizing mafuta ndi zitsulo slag ntchito, ndipo ali kwambiri kukana ozoni, mkulu-kutentha cheza kukana ndi kukana madzi otentha.
Kuchokera pamwamba makhalidwe a HNBR, poyerekeza ndi FKM, kale bwino zonse ntchito, FKM, ngakhale mu kukana kutentha, kukana mafuta, kukana kuyaka mafuta ndi bwino kuposa HNBR, koma HNBR mu kutentha ntchito makina a kukana nthunzi, kukana zina zowonjezera mafuta, kukana makutidwe ndi okosijeni ndi rancidity kuwonongeka kwa mafuta ndi zina katundu mankhwala monga FK superi mankhwala monga FK. Kuphatikiza apo, FKM pakupanga ndi kuumba chifukwa cha kusayenda bwino kwa zinthuzo, zopangira komanso magwiridwe antchito sizokhazikika, chifukwa chake mtengo wake. Kuphatikiza apo, FKM ndi yokwera mtengo kwambiri popanga ndi kuumba chifukwa cha kusayenda bwino kwa zinthu, zopangira zosakhazikika komanso magwiridwe antchito, pomwe HNBR ndi yotsika mtengo kuposa FKM chifukwa chopanga zinthu zabwino komanso kukonza, magwiridwe antchito okhazikika komanso mtengo wotsika.
Momwe HNBR ikugwiritsidwira ntchito ndikuwunika momwe imagwirira ntchito pamakina omanga
Chifukwa cha ntchito bwino mabuku HNBR, wakhala ankagwiritsa ntchito m'mbali zambiri m'malo FKM m'mayiko akunja: wakhala ntchito mu makampani magalimoto kupanga galimoto crankshaft kutsogolo ndi kumbuyo ndi gearbox mafuta zisindikizo, H-mtundu kutsinde zisindikizo, zisindikizo kwa dongosolo jekeseni mafuta, pisitoni yamphamvu kugwedera kugwedera zisindikizo zotayira, carbure, etc. ndi mafakitale zitsulo, ntchito kupanga zitsulo mkulu-mzere Kugubuduza mphero chitsulo chogwira chitsulo m'mimba mwake awiri mbali zisindikizo, ndi zisindikizo kwa masilindala zimakupiza zoboola pakati mu zoweta mosalekeza kuponyera makina; ndipo m’makampani opangira mafuta, amagwiritsidwa ntchito popanga zida zobowolera, komanso zosindikizira pobowola. M'makampani opangira mafuta, amagwiritsidwa ntchito kupanga chisindikizo chachitetezo chobowola pobowola chisindikizo chamutu, kusindikiza pampu yamafuta, ndi zina zotero.
Kwa zojambulira ndi makina ena omanga, zida zake zotumizira ma hydraulic monga ma gearbox, torque converter mkati mwa kutentha kwanthawi yayitali akuti 8O-90 ℃ , apamwamba kwambiri sapitilira 120 ℃ , koma monga maola ochuluka a ntchito yodzaza. Mpaka kapena kuposa 130 ℃ mkati mkombero wa mkulu-kutentha madzimadzi kuwonongeka ndi kuwonongeka pakapita nthawi, pamene mbali za slag zitsulo (meshing kayendedwe ka zigawo zitsulo ndi nthawi ya ntchito ndondomeko ya zitsulo shavings kugwa sing'anga ntchito) mu mkulu-kutentha mafuta otentha motsogozedwa ndi zisindikizo chifukwa cha kukhudza kwa zisindikizo moyo wa zisindikizo.
Choncho, HNBR angagwiritsidwe ntchito mu mphamvu kutentha kutentha, otsika kutentha kukana, kutentha psinjika okhazikika mapindikidwe, makutidwe ndi okosijeni ndi asidi kuwonongeka kwa mafuta ndi zitsulo sludge ntchito ndi mbali zina za mtengo wa ubwino anasonyeza, ndi m'malo mwa chisindikizo panopa FKM, onse kusintha moyo utumiki wa zisindikizo, komanso kuchepetsa pafupipafupi m'malo sing'anga ntchito; ndipo kukana kutentha kwa FKM ndikochepa kwambiri. Kwa makina opangira makina opangira ma hydraulic system, makina ogwiritsira ntchito mphamvu nthawi zambiri amakhala 16MPa (ndi makina othamanga kwambiri), sing'anga yogwira ntchito (HM46 kapena HM32 hydraulic mafuta) ya kutentha kwapang'onopang'ono kwa 45-55 ℃ , chifukwa cha magwiridwe antchito a chipangizocho ndi osauka, kuphatikiza ndi ntchito yosayenera ya wogwiritsa ntchito, komanso kuyendetsa bwino dongosolo lazachuma. kutentha kwa mafuta othamanga Kuposa malire awa, motero kumayambitsa kuwonongeka kwa mafuta a hydraulic.
Kuphatikiza apo, mapangidwe a ma hydraulic system of high-speed rotary movement (hydraulic pump) komanso kutsetsereka pafupipafupi (hydraulic cylinder piston rod ndi multi-way reversing valve valve stem) kumapangitsanso zitsulo zachitsulo ndi kuwonongeka kwa mafuta, zisindikizo zimayambanso chifukwa cha kugundana, kutayika kwa dongosololi ndi kutayika koopsa komwe kumabwera chifukwa cha kuchepa kwamphamvu, kuchepa kwapang'onopang'ono ndi kutsika kwapang'onopang'ono. Pazisindikizo zamakono za NBR, chifukwa cha mphamvu zake zowonongeka komanso kukana kuwonongeka kwa katundu wa mafuta Kwa zisindikizo za NBR zomwe zilipo, chifukwa cha mphamvu zake zowonongeka ndi kukana kuwonongeka kwa mafuta komanso zosavuta kulephera, chifukwa cha mphamvu ya HNBR, kuchira bwino, mbali ya kutayika kwadzidzidzi kwa kupanikizika kwa ntchito za zidindo sikukhudzidwa pang'ono, kotero mu hydraulic system, hydraulic system, hydraulic system, hydraulic system, hydraulic system, hydraulic system, hydraulic system, hydraulic system, hydraulic system, hydraulic system, hydraulic system, hydraulic system, hydraulic system, Zisindikizo za HNBR zimatha kusintha kwambiri kusindikiza ko
