Ungayikhetha kanjani indandatho yokuvala yohlelo lwe-hydraulic?
1. Indandatho yokuvala irabha ye-nitrile ye-NBR ifanele ukusetshenziswa ku-oyili we-hydraulic kaphethiloli, uwoyela we-hydraulic we-ethylene glycol, uwoyela wokugcoba we-diester, uphethiloli, amanzi, i-silicone grease, uwoyela we-silicone nakwezinye izinto. Yiyona esetshenziswa kakhulu futhi ebiza kancane kakhulu irabha. Ayifanele ukusetshenziswa ku-solvents ezi-polar ezifana nama-ketone, i-ozone, ama-nitrohydrocarbon, i-MEK kanye ne-chloroform. Ububanzi bokushisa obujwayelekile bokusetshenziswa bungu-40~120 ℃. Okwesibili, indandatho yokuvala irabha ye-nitrile ene-hydrogenated HNBR inokumelana okuhle kakhulu nokugqwala, ukumelana nokudabuka kanye nezici zokuguquguquka kokucindezela, ukumelana ne-ozone, ukumelana nokukhanya kwelanga, ukumelana nesimo sezulu kuhle. Ukumelana nokuguguleka okungcono kunerabha ye-nitrile. Ifanele imishini yokuwasha, izinhlelo zezinjini zezimoto kanye nezinhlelo zokuqandisa ezisebenzisa i-refrigerant entsha enobungani nemvelo i-R134a. Ayikhuthazwa ukusetshenziswa ku-alcohols, ama-esters, noma izixazululo ze-aromatic. Ububanzi bokushisa obujwayelekile bokusetshenziswa bungu-40~150 ℃. Okwesithathu, indandatho yokuvala irabha ye-FLS fluorine silicone inezinzuzo zerabha ye-fluorine kanye nerabha ye-silicone, ukumelana namafutha, ukumelana ne-solvent, ukumelana namafutha kaphethiloli kanye nokumelana nokushisa okuphezulu nokuphansi kuhle. Imelana nokuhlaselwa kwamakhemikhali aqukethe umoya-mpilo, izinyibilikisi eziqukethe i-hydrocarbon enuka kamnandi kanye nezinyibilikisi eziqukethe i-chlorine. Ngokuvamile isetshenziselwa izindiza, izindiza kanye nezinjongo zempi. Ukuchayeka kuma-ketone kanye noketshezi lwamabhuleki akukhuthazwa. Ibanga lokushisa elijwayelekile liyi--50~200 ℃.
2, ngaphezu kwezidingo ezijwayelekile zezinto zokubopha indandatho, indandatho yokubopha kufanele futhi inake lezi zimo ezilandelayo: (1) ukunwebeka nokuqina; (2) Amandla afanele omshini, kufaka phakathi amandla okukhulisa, ukunwebeka kanye namandla okudabula. (3) Ukusebenza kuzinzile, akulula ukuvuvukala endaweni yokusebenzela, futhi umphumela wokuncipha kokushisa (umphumela we-Joule) mncane. (4) Kulula ukucubungula nokubumba, futhi kungagcina usayizi oqondile. (5) akugqwali indawo yokuxhumana, akungcolisi indawo yokusebenzela, njll. Izinto ezifanele kakhulu nezisetshenziswa kakhulu ukuhlangabezana nezidingo ezingenhla irabha, ngakho-ke indandatho yokubopha yenziwe kakhulu ngezinto zerabha. Kunezinhlobo eziningi zerabha, futhi kunezinhlobo zerabha ezintsha njalo, ukwakheka nokukhetha, kufanele kuqondwe izici zerabha ezahlukene, ukukhetha okunengqondo.
3. Izinzuzo
(1) Indandatho yokuvala kufanele ibe nokusebenza kahle kokuvala ekucindezelweni kokusebenza kanye nobubanzi obuthile bokushisa, futhi ingathuthukisa ngokuzenzakalelayo ukusebenza kokuvala ngokwanda kwengcindezi.
(2) Ukungqubuzana phakathi kwedivayisi yendandatho yokuvala kanye nezingxenye ezihambayo kufanele kube kuncane, futhi i-coefficient yokungqubuzana kufanele iqine.
(3) Indandatho yokuvala inokumelana okuqinile nokugqwala, akulula ukuyiguga, isebenza isikhathi eside, iyakwazi ukumelana nokugqwala kahle, futhi ingakhokhelwa ngokuzenzakalelayo ngemva kokugqwala ngezinga elithile.
(4) Isakhiwo esilula, okulula ukusisebenzisa nokuyinakekela, ukuze indandatho yokuvala ihlale isikhathi eside. Umonakalo wendandatho yokuvala uzobangela ukuvuza, okuholela ekuchithekeni kwemidiya yokusebenza, ukungcola komshini kanye nemvelo, futhi kubangele ngisho nokwehluleka kokusebenza kwemishini kanye nezingozi zomuntu siqu zemishini. Ukuvuza kwangaphakathi kuzobangela ukuthi ukusebenza kahle kwesistimu ye-hydraulic kwehle kakhulu, futhi ingcindezi yokusebenza edingekayo ayikwazi ukufinyelelwa, noma ngisho nomsebenzi awukwazi ukwenziwa. Izinhlayiya ezincane zothuli ezihlasela uhlelo zingabangela noma zikhulise ukuguguleka kwezimbangi zokungqubuzana kwezingxenye ze-hydraulic, okuholela ekuvuzeni. Ngakho-ke, izimbobo kanye namadivayisi okuvala kuyingxenye ebalulekile yemishini ye-hydraulic. Ukuthembeka kanye nokuphila kwenkonzo yomsebenzi wayo kuyisibonakaliso esibalulekile sokulinganisa ikhwalithi yesistimu ye-hydraulic.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
