Cov kev cai tshwj xeeb rau fasteners nyob rau hauv lub zog tshiab lub tsheb qauv feem ntau yog tsom rau lub teeb yuag, siab zog, rwb thaiv tsev, corrosion kuj, thiab tiv thaiv -loosing kev ua tau zoo los tiv nrog lub siab -voltage ib puag ncig ntawm peb- hluav taws xob system, xav tau rau tag nrho lub tsheb qhov hnyav txo, thiab cov teeb meem ntawm kev khiav hauj lwm nyuaj.
Sib npaug sib sib zog nqus thiab siab zog
Vim qhov hnyav hnyav ntawm lub pob roj teeb, lub zog tshiab tsheb muaj cov kev xav tau ntau dua rau kev siv lub teeb yuag tag nrho, thiab cov fasteners yuav tsum ua tiav "qhov hnyav dua yam tsis muaj lub zog."
Aluminium alloy, titanium alloy, thiab siab -kev ua tau zoo engineering yas (xws li PEEK) fasteners yog dav siv. Lawv qhov ceev tsuas yog 1/5-1/3 ntawm cov hlau, tab sis lawv lub zog yog piv rau 8.8 lossis txawm tias 10.9 qib steel bolts.
Carbon fiber reinforced composite cov ntaub ntawv fasteners yog siv nyob rau hauv lub roj teeb pob qauv kom ua tiav ob lub hom phiaj ntawm kev poob phaus thiab qaug zog.
High-Vim hluav taws xob rwb thaiv tsev thiab hluav taws xob kev nyab xeeb
Kev khiav hauj lwm voltage ntawm peb - hluav taws xob system (roj teeb, lub cev muaj zog, thiab hluav taws xob tswj) feem ntau ncav cuag 400V-800V, thiab fasteners yuav tsum muaj cov rwb thaiv tsev zoo.
The dielectric strength must be >30kV/mm, and the volume resistivity >10¹⁵Ω·cm los tiv thaiv galvanic corrosion los yog luv Circuit Court nyob rau hauv siab -voltage circuits.
PEEK cov ntsia hlau tshwj xeeb tau siv dav hauv cov tshuab hluav taws xob, muab 100 npaug ntawm kev ua haujlwm zoo rwb thaiv tsev thiab txo qhov kev pheej hmoo ntawm kev vibration loosening los ntawm 90%.
Ib puag ncig tsis kam:
Fasteners yuav tsum muaj peev xwm ua haujlwm nyob rau hauv qhov kub ntawm -40℃txog 180 degree, tshwj xeeb tshaj yog nyob rau hauv lub cev muaj zog thiab roj teeb.
Lawv yuav tsum xeem dhau qhov kev xeem suav nrog Ntau dua lossis sib npaug li 500 teev ntawm kev ntsuas tshuaj ntsev, UV aging kuj, thiab thermal cycling shock resistance.
Tuag-cam khwb cia txhuas vaj tse txuas siv cov thev naus laus zis kho mob xws li micro-arc oxidation thiab Dacromet txheej los txhim kho corrosion kuj.
