Momwe mungasankhire mphete yosindikiza ya hydraulic system?
1. NBR nitrile mphira kusindikiza mphete ndi yoyenera kugwiritsidwa ntchito mu petroleum hydraulic mafuta, ethylene glycol hydraulic mafuta, diester lubricating mafuta, mafuta, madzi, silikoni girisi, silikoni mafuta ndi zina. Ndicho chisindikizo cha rabara chomwe chimagwiritsidwa ntchito kwambiri komanso chotsika mtengo. Osagwiritsa ntchito polar solvents monga ketoni, ozoni, nitrohydrocarbons, MEK ndi chloroform. Ambiri ntchito kutentha osiyanasiyana -40 ~ 120 ℃. Chachiwiri, mphete yosindikizira ya HNBR ya hydrogenated nitrile ili ndi kukana kwa dzimbiri, kukana misozi ndi mawonekedwe opindika, kukana kwa ozoni, kukana kwa dzuwa, kukana kwanyengo ndikwabwino. Kukana kuvala bwino kuposa mphira wa nitrile. Oyenera makina ochapira, makina a injini zamagalimoto ndi kachitidwe ka firiji pogwiritsa ntchito refrigerant yatsopano yosunga zachilengedwe R134a. Osavomerezeka kuti agwiritsidwe ntchito pazakumwa zoledzeretsa, ma esters, kapena onunkhira. Ambiri ntchito kutentha osiyanasiyana -40 ~ 150 ℃. Chachitatu, FLS fluorine silikoni wosindikiza mphete ali ndi ubwino wa mphira fluorine ndi silikoni mphira, kukana mafuta, kukana zosungunulira, kukana mafuta mafuta ndi mkulu ndi otsika kukana kutentha ndi zabwino. Ndi kugonjetsedwa ndi kuukira kwa mpweya munali mankhwala, onunkhira hydrocarbon munali solvents ndi chlorine munali zosungunulira. Nthawi zambiri amagwiritsidwa ntchito popanga ndege, zamlengalenga komanso zankhondo. Kukumana ndi matupi a ketoni ndi ma brake fluid sikuvomerezeka. Ambiri ntchito kutentha osiyanasiyana -50 ~ 200 ℃.
2, kuwonjezera pa zofunikira zonse za mphete yosindikizira, mphete yosindikizira iyeneranso kulabadira zotsatirazi: (1) zotanuka ndi zolimba; (2) Mphamvu yoyenera yamakina, kuphatikiza mphamvu yakukulitsa, kutalika ndi kung'amba mphamvu. (3) Kuchitako kumakhala kokhazikika, sikophweka kutupa pakati, ndipo kutentha kwapakati (Joule effect) ndi kochepa. (4) Zosavuta kukonza ndi kuumba, ndipo zimatha kusunga kukula kwake. (5) sichiwononga malo okhudzana, sichiipitsa sing'anga, ndi zina zotero. Zinthu zoyenera komanso zomwe zimagwiritsidwa ntchito kwambiri kuti zikwaniritse zofunikira zomwe zili pamwambazi ndi mphira, kotero mphete yosindikizira imakhala yopangidwa ndi mphira. Pali mitundu yambiri ya mphira, ndipo pali mitundu yatsopano ya mphira nthawi zonse, mapangidwe ndi kusankha, ayenera kumvetsetsa mawonekedwe a rabala osiyanasiyana, kusankha koyenera.
3. Ubwino
(1) Mphete yosindikizira iyenera kukhala ndi ntchito yabwino yosindikizira pakukakamiza kogwirira ntchito komanso kutentha kwina, ndipo imatha kupititsa patsogolo ntchito yosindikiza ndikuwonjezera kukakamiza.
(2) Mkangano pakati pa chipangizo cha mphete yosindikizira ndi zigawo zosuntha ziyenera kukhala zazing'ono, ndipo coefficient of friction iyenera kukhala yokhazikika.
(3) Mphete yosindikizira imakhala ndi kukana kwa dzimbiri kolimba, sikophweka kukalamba, imakhala ndi moyo wautali wogwira ntchito, kukana kuvala bwino, ndipo imatha kulipidwa pokhapokha atavala mpaka kufika pamlingo winawake.
(4) Mapangidwe osavuta, osavuta kugwiritsa ntchito ndikuwongolera, kuti mphete yosindikiza ikhale ndi moyo wautali. Kuwonongeka kwa mphete zosindikizira kumayambitsa kutayikira, zomwe zimabweretsa kuwonongeka kwa makina osindikizira, kuwononga makina ndi chilengedwe, komanso kuchititsa kulephera kwa makina komanso ngozi zamunthu. Kutayikira kwamkati kumapangitsa kuti mphamvu ya ma hydraulic igwe kwambiri, ndipo kukakamizidwa kofunikirako sikungafikidwe, kapena ngakhale ntchitoyo siyingachitike. Tizilombo tating'onoting'ono tomwe timalowa m'dongosololi titha kuyambitsa kapena kukulitsa kuvala kwa ma hydraulic particles, zomwe zimapangitsa kutayikira. Chifukwa chake, zisindikizo ndi zida zosindikizira ndizofunikira kwambiri pazida zama hydraulic. Kudalirika ndi moyo wautumiki wa ntchito yake ndi chizindikiro chofunikira choyezera mtundu wa hydraulic system.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
