Zobisika pakusankha ndi kukhazikitsa zisindikizo zamafuta

Chosindikizira mafuta ndi chipangizo chomwe chimapangidwa kuti chisindikize malo ozungulira agalimoto.Ngakhale zikuwoneka kuti ndizosavuta komanso zambiri zogwiritsidwa ntchito pamagalimoto, mapangidwe ndi kusankha kwa gawoli ndi ntchito yofunika komanso yovuta.

 

Lingaliro lolakwika 1: Kusankha chosindikizira chamafuta, ndikokwanira kudziwa kukula kwake

Kukula ndikofunikira, koma kutali ndi gawo lokhalo.Ndi kukula komweko, zisindikizo zamafuta zimatha kusiyana kwambiri muzochita zawo komanso kukula kwake.Kuti mupange chisankho choyenera, muyenera kudziwa kutentha kwa kutentha komwe chisindikizo cha mafuta chidzagwira ntchito, njira yozungulira shaft yoyikapo, kaya mapangidwe apangidwe monga mabere awiri amafunikira.

Kutsiliza: pakusankha kolondola kwa chisindikizo chamafuta, muyenera kudziwa magawo ake onse, ndi zofunikira zotani zomwe zimayikidwa ndi wopanga magalimoto.

 

Malingaliro olakwika 2. Zisindikizo zamafuta ndizofanana ndipo kusiyana kwamitengo kumachokera ku umbombo wa wopanga.

Ndipotu, zisindikizo zamafuta zimatha kupangidwa ndi zinthu zosiyanasiyana kapena njira zosiyanasiyana.

Zida zomwe zimagwiritsidwa ntchito popanga zisindikizo zamafuta:

● ACM (rabara ya acrylate) - kutentha kwa ntchito -30 ° C ... + 150 ° C. Zinthu zotsika mtengo, zomwe zimagwiritsidwa ntchito nthawi zambiri popanga zisindikizo za mafuta a hub.
● NBR (raba yosagwira mafuta ndi mafuta) - kutentha kwa ntchito -40 ° C ... + 120 ° C. Amadziwika ndi kukana kwakukulu kwa mitundu yonse ya mafuta ndi mafuta.
● FKM (fluororubber, fluoroplastic) - kutentha kwa ntchito -20 ° C ... + 180 ° C. Zomwe zimagwiritsidwa ntchito kwambiri popanga zisindikizo za mafuta a camshaft, crankshafts, etc. Zimatsutsana kwambiri ndi mitundu yosiyanasiyana ya zidulo, monga komanso mankhwala, mafuta, mafuta ndi zosungunulira.
● FKM + (otchedwa fluororubbers okhala ndi zowonjezera zapadera) - kutentha kwa ntchito -50 ° C ... + 220 ° C. Zida zovomerezeka zopangidwa ndi chiwerengero chachikulu cha mankhwala (Kalrez ndi Viton (opangidwa ndi DuPont), Hifluor (opangidwa ndi Parker) , komanso zipangizo Dai-El ndi Aflas).Iwo amasiyana ochiritsira fluoroplastic ndi yaitali kutentha osiyanasiyana ndi kuwonjezeka kukana zidulo ndi mafuta ndi lubricant.

 

Ndikofunikanso kuzindikira kuti panthawi yogwira ntchito, chisindikizo cha mafuta sichimakhudza pamwamba pa shaft, chisindikizocho chimachitika chifukwa cha kupangidwa kwa vacuum m'dera la kuzungulira kwa shaft pogwiritsa ntchito mapepala apadera.Kuwongolera kwawo kuyenera kuganiziridwa posankha, apo ayi nsonga sizidzayamwa mafuta m'thupi, koma m'malo mwake - zitulutse pamenepo.

Pali mitundu itatu ya ma notches:

● Kuzungulira kolondola
● Kuzungulira kumanzere
● Zosintha

 

Kuphatikiza pa zinthuzo, zisindikizo zamafuta zimasiyananso ndiukadaulo wopanga.Masiku ano, njira ziwiri zopangira zimagwiritsidwa ntchito: kupanga ndi matrix, kudula kuchokera kuzinthu zopanda kanthu ndi wodula.Pachiyambi choyamba, kupatuka kwa miyeso ndi magawo a chisindikizo chamafuta sikuloledwa pamlingo waukadaulo.Chachiwiri, ndi kuchuluka kwakukulu kwa kupanga, kupatuka kwa kulolerana ndikotheka, chifukwa chake chisindikizo chamafuta chimakhala ndi miyeso yosiyana ndi yomwe yatchulidwa.Chisindikizo chamafuta choterocho sichingapereke chisindikizo chodalirika ndipo chimayamba kutsika kuyambira pachiyambi, kapena kulephera mwamsanga chifukwa cha kukangana pamtengowo, kuwononga nthawi yomweyo pamwamba pa shaft yokha.

Kugwira chisindikizo chatsopano chamafuta m'manja mwanu, yesetsani kupindika m'mphepete mwake: mu chisindikizo chatsopano chamafuta, chiyenera kukhala chotanuka, ngakhale chakuthwa.Kukuthwa kwake, m'pamenenso chisindikizo chatsopano chamafuta chidzagwira ntchito bwino komanso motalika.

Pansipa pali tebulo lofananizira lachisindikizo chamafuta, kutengera mtundu wa zida ndi njira yopangira:
