Ni gute wahitamo impeta yo gufunga kuri sisitemu ya hydraulic?
1. Impeta yo gufunga ya NBR nitrile ikwiriye gukoreshwa mu mavuta ya peteroli, amavuta ya ethylene glycol hydraulic, amavuta yo kwisiga ya diester, lisansi, amazi, amavuta ya silicone, amavuta ya silicone n'ibindi bikoresho. Ni yo mpushya ikoreshwa cyane kandi ihendutse cyane. Ntikwiriye gukoreshwa mu bintu bisukura ikirere nka ketones, ozone, nitrohydrocarbons, MEK na chloroform. Ingano y'ubushyuhe rusange ni -40 ~ 120 ℃. Icya kabiri, impeta yo gufunga ya HNBR nitrile ifite ubushobozi bwo kurwanya ingese, kurwanya amarira no gukanda, kurwanya ozone, kurwanya imirasire y'izuba, kurwanya ikirere ni byiza. Ifite ubushobozi bwo kurwanya ingese kurusha nitrile. Ikwiriye gukoreshwa mu mashini zoza, moteri z'imodoka na sisitemu zo gukonjesha hakoreshejwe firigo nshya ya R134a idahumanya ibidukikije. Ntibyemewe gukoreshwa mu bintu birimo alcool, esters, cyangwa aromatic. Ingano y'ubushyuhe rusange ni -40 ~ 150 ℃. Icya gatatu, impeta yo gufunga ya FLS fluorine silicone ifite ibyiza bya fluorine rubber na silicone rubber, irwanya amavuta, irwanya solvent, irwanya amavuta ya lisansi ndetse n'irwanya ubushyuhe bwinshi n'ubushyuhe buke ni byiza. Irwanya ibitero by'ibintu birimo ogisijeni, irwanya solvent irimo aromatic hydrocarbon na solvent irimo chlorine. Muri rusange ikoreshwa mu ndege, mu kirere no mu bikorwa bya gisirikare. Ntibyemewe ko ihura na ketones n'amazi ya feri. Ubushyuhe rusange bukoreshwa ni -50~200 ℃.
2, uretse ibisabwa rusange ku bikoresho byo gufunga, impeta yo gufunga igomba kandi kwita ku bintu bikurikira: (1) guhindagurika no gukomera; (2) Ingufu zikwiye za mekanike, harimo imbaraga zo kwaguka, uburebure n'imbaraga zo gucika. (3) Imikorere yayo irahamye, ntabwo byoroshye kubyimba mu buryo bw'umwuka, kandi ingaruka zo gufungana k'ubushyuhe (Joule effect) ni nto. (4) Byoroshye gutunganya no gushushanya, kandi bishobora kugumana ingano nyayo. (5) ntibingiza ubuso bufatanye, ntibihumanya imiterere y'icyuma, nibindi. Ibikoresho bikwiye kandi bikunze gukoreshwa cyane kugira ngo byuzuze ibisabwa byavuzwe haruguru ni rubber, bityo impeta yo gufunga ikorwa ahanini mu bikoresho bya rubber. Hariho ubwoko bwinshi bwa rubber, kandi hariho ubwoko bushya bwa rubber, imiterere n'uburyo bwo guhitamo, bagomba gusobanukirwa imiterere ya rubber zitandukanye, guhitamo neza.
3. Ibyiza
(1) Impeta yo gufunga igomba kugira imikorere myiza yo gufunga mu gitutu cy'akazi n'ubushyuhe runaka, kandi ishobora kunoza imikorere yo gufunga mu buryo bwikora iyo igitutu cyiyongere.
(2) Uguhuzagurika hagati y'igikoresho gifunga n'ibice bigenda bigomba kuba bito, kandi igipimo cy'uguhuzagurika kigomba kuba gihamye.
(3) Impeta yo gufunga ifite ubushobozi bwo kurwanya ingese, ntiyoroshye gusaza, imara igihe kirekire ikora, irakomera cyane, kandi ishobora kwishyurwa mu buryo bwikora nyuma yo kwangirika ku rugero runaka.
(4) Imiterere yoroshye, yoroshye gukoresha no kubungabunga, kugira ngo impeta yo gufunga irambe igihe kirekire. Kwangirika kw'impeta yo gufunga bizatera gusohoka, bigatera gupfusha ubusa ibikoresho bikora, kwanduza imashini n'ibidukikije, ndetse bigatera impanuka ku mikorere y'ibikoresho. Gusohoka imbere mu mashini bizatuma imikorere y'amazi igabanuka cyane, kandi umuvuduko ukenewe wo gukora ntushobore kugerwaho, cyangwa ngo n'akazi kakorwe. Uduce duto tw'umukungugu twinjira muri sisitemu dushobora gutera cyangwa kongera kwangirika kw'ibice by'amazi, bikarushaho gutera gusohoka. Kubwibyo, ibikoresho byo gufunga ni igice cy'ingenzi cy'ibikoresho byo gufunga. Kwizerwa no kumara igihe cy'akazi kayo ni ikimenyetso cy'ingenzi cyo gupima ubuziranenge bwa sisitemu yo gufunga.
Zhuo Meng Shanghai Auto Co., Ltd. yiyemeje kugurisha ibice by'imodoka bya MG & MAUXS.
