Kodi mungasankhe bwanji mphete yotsekera ya dongosolo la hydraulic?
1. Mphete yotsekera mphira ya nitrile ya NBR ndi yoyenera kugwiritsidwa ntchito mu mafuta a hydraulic a petroleum, mafuta a ethylene glycol hydraulic, mafuta odzola a diester, mafuta a petulo, mafuta a petulo, madzi, mafuta a silicone, mafuta a silicone ndi zina zotero. Ndi chisindikizo cha mphira chomwe chimagwiritsidwa ntchito kwambiri komanso chotsika mtengo. Sichoyenera kugwiritsidwa ntchito mu zosungunulira za polar monga ma ketones, ozone, nitrohydrocarbons, MEK ndi chloroform. Kutentha komwe kumagwiritsidwa ntchito nthawi zambiri ndi -40~120 ℃. Chachiwiri, mphete yotsekera mphira ya nitrile ya HNBR hydrogenated ili ndi kukana dzimbiri bwino, kukana misozi ndi kupsinjika, kukana ozone, kukana dzuwa, kukana nyengo ndikwabwino. Kukana kuvala bwino kuposa mphira ya nitrile. Yoyenera makina ochapira, makina a injini zamagalimoto ndi makina oziziritsira pogwiritsa ntchito firiji yatsopano ya R134a yoteteza chilengedwe. Sikoyenera kugwiritsidwa ntchito mu alcohols, esters, kapena aromatic solutions. Kutentha komwe kumagwiritsidwa ntchito nthawi zambiri ndi -40~150 ℃. Chachitatu, mphete yotsekera mphira ya silicone ya fluorine ya FLS ili ndi ubwino wa mphira wa fluorine ndi silicone, kukana mafuta, kukana zosungunulira, kukana mafuta amafuta ndi kukana kutentha kwambiri ndi kotsika. Imalimbana ndi zinthu zokhala ndi mpweya, zosungunulira zokhala ndi hydrocarbon ndi zosungunulira zokhala ndi chlorine. Nthawi zambiri imagwiritsidwa ntchito poyendetsa ndege, ndege ndi usilikali. Sikoyenera kukhudzana ndi ma ketone ndi ma brake fluids. Kutentha komwe kumagwiritsidwa ntchito nthawi zambiri ndi -50~200 ℃.
2, kuwonjezera pa zofunikira zonse za mphete yotsekera, mphete yotsekera iyeneranso kulabadira zinthu zotsatirazi: (1) zotanuka komanso zolimba; (2) Mphamvu yoyenera yamakina, kuphatikiza mphamvu yokulira, kutalika ndi mphamvu yong'ambika. (3) Kagwiridwe kake ndi kokhazikika, sikophweka kutupa mu sing'anga, ndipo mphamvu ya kutentha (Joule effect) ndi yaying'ono. (4) Yosavuta kukonza ndi kupanga, ndipo imatha kusunga kukula kolondola. (5) siiwononga pamwamba pa kukhudzana, siipitsa sing'anga, ndi zina zotero. Zipangizo zoyenera komanso zomwe zimagwiritsidwa ntchito kwambiri kuti zikwaniritse zofunikira pamwambapa ndi rabala, kotero mphete yotsekera imapangidwa kwambiri ndi zinthu za rabala. Pali mitundu yambiri ya rabala, ndipo nthawi zonse pamakhala mitundu yatsopano ya rabala, kapangidwe ndi kusankha, ayenera kumvetsetsa makhalidwe a rabala osiyanasiyana, kusankha koyenera.
3. Ubwino
(1) Mphete yotsekera iyenera kukhala ndi magwiridwe antchito abwino otsekera pakapanikizika kogwira ntchito komanso kutentha kwina, ndipo imatha kusintha magwiridwe antchito otsekera pokhapokha ngati kuthamanga kwa mpweya kukukwera.
(2) Kukangana pakati pa chipangizo chotsekera ndi zinthu zosuntha kuyenera kukhala kochepa, ndipo coefficient of friction iyenera kukhala yokhazikika.
(3) Mphete yotsekera imakhala ndi mphamvu yolimbana ndi dzimbiri, siikalamba mosavuta, imakhala ndi nthawi yayitali yogwira ntchito, imakana kuvala bwino, ndipo imatha kulipidwa yokha ikawonongeka pamlingo winawake.
(4) Kapangidwe kosavuta, kosavuta kugwiritsa ntchito ndi kusamalira, kotero kuti mphete yotsekera imakhala ndi moyo wautali. Kuwonongeka kwa mphete yotsekera kudzayambitsa kutayikira, zomwe zimapangitsa kuti zinthu zogwirira ntchito ziwonongeke, kuipitsa makina ndi chilengedwe, komanso kuyambitsa kulephera kwa makina ndi ngozi za anthu paokha. Kutayikira kwamkati kudzapangitsa kuti mphamvu yamagetsi ya makina otsekera itsike kwambiri, ndipo kuthamanga kofunikira kogwira ntchito sikungatheke, kapena ngakhale ntchitoyo singachitike. Tinthu tating'onoting'ono ta fumbi tomwe timalowa mu makinawo tingayambitse kapena kukulitsa kuwonongeka kwa mawiri okangana a zigawo za hydraulic, zomwe zimapangitsa kuti zituluke. Chifukwa chake, zisindikizo ndi zida zotsekera ndi gawo lofunikira la zida za hydraulic. Kudalirika ndi moyo wautumiki wa ntchito yake ndi chizindikiro chofunikira poyesa mtundu wa makina otsekera.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zikulandiridwa kugula.
