Ndi mavuto ati omwe akuyenera kutsatiridwa pakusankha zisindikizo za rabara
Kusankhidwa kwa zisindikizo za mphira kuyenera kuganizira momwe ntchito ikugwirira ntchito, kuti asankhe mawonekedwe abwino a zisindikizo ndi zipangizo zosindikizira, kapangidwe kake.
Kusankhidwa kwa zisindikizo za rabara kumayenera kuganizira momwe ntchito zimakhalira: kutentha, kuthamanga, sing'anga.Zina zimafunika kuphatikizidwa ndi mawonekedwe a zida zomwezo kuti ziganizire kusankha zisindikizo.
Za kutentha, monga kusindikiza zakuthupi NBR zakuthupi ntchito kutentha osiyanasiyana zambiri -40 ~ +120 ℃.Ndi oposa 120 ℃ kuganizira ntchito FKM, ngakhale PTFE zakuthupi, kutentha otsika ndi osowa, ambiri kulankhula pa nkhani ya -20 ~ -40 ℃ kuganizira ntchito ozizira kugonjetsedwa NBR, NBR zakuthupi ambiri pa otsika. kutentha chilengedwe kudzachititsa kuti zinthu kuumitsa, chifukwa kutayikira, monga njanji locomotive kumpoto kwa dzinja zambiri kuoneka mavuto amenewa.
Ponena za kukakamizidwa, kumakhudza mawonekedwe a zisindikizo zomwe zimayenera kusankhidwa.Nthawi zambiri, kugwiritsa ntchito mphira kapena zisindikizo za PU pakutsika kotsika komanso kupanikizika kwapakatikati sikukhala ndi vuto lalikulu.Koma kuganizira vuto la kupanikizika kwamphamvu, monga makina omanga poyambira, kutseka pamene mphamvu yake imakhala yaikulu kwambiri kuposa mphamvu yogwira ntchito, choncho nthawi zambiri amasankha kukakamiza mpaka 70MPA yotsutsana ndi kufinya HBY kapena SPGW ngati chisindikizo chachikulu. .PTFE zisindikizo zophatikizika nazonso ndizofala.
Vuto lapakati ndilosavuta.Ingodziwani zamavuto ang'onoang'ono apadera, monga silinda yamakampani opanga zitsulo nthawi zambiri amagwiritsa ntchito madzi-glycol ndi phosphate hydraulic fluids.Nthawi zina, ngakhale kutentha ntchito si mkulu, koma kusankha zipangizo kusindikiza ayenera kusamala kwambiri, hayidiroliki mafuta ntchito pamene yotsirizira kapena FKM.
Kusankhidwa kwa zisindikizo ndikofunikira kwambiri, kapena kuyenera kuphatikizidwa ndi momwe zida ziliri zomwe mungasankhe.
