2. Nylon Washers:Nylon washers yog lub teeb yuag, muaj zog, thiab tiv taus corrosion. Lawv feem ntau siv rau hauv kev siv hluav taws xob thiab hluav taws xob vim lawv cov khoom zoo heev insulating. Nylon washers kuj tiv taus cov tshuaj thiab tuaj yeem tiv taus qhov kub thiab txias.
3. Polyurethane Washers:Polyurethane ntxhua khaub ncaws paub txog lawv lub peev xwm ua haujlwm siab thiab tiv taus hnav thiab tsim kua muag. Lawv feem ntau yog siv rau hauv cov tshuab hnyav thiab cov cuab yeej siv uas ua haujlwm ntev yog qhov tseem ceeb. Polyurethane ntxhua khaub ncaws muaj kev tiv thaiv zoo rau cov roj, tshuaj, thiab puas.
Lwm yam muaj zog Washers:
Sib nrug los ntawm cov hlau, roj hmab, thiab cov tshuab ntxhua khaub ncaws, muaj lwm hom ntxhua khaub ncaws uas muaj zog tshwj xeeb thiab kev ua haujlwm zoo. Nov yog qee qhov piv txwv:
1. Fiber Washers:Fiber washers yog tsim los ntawm cov ntaub ntawv xws li ntawv, cardboard, los yog hluavtaws fibers. Lawv yog lub teeb yuag thiab muab lub foob zoo. Fiber washers feem ntau yog siv rau hauv cov kav dej thiab kev siv tsheb.
2. Dome Washers:Dome washers, tseem hu ua Belleville washers, yog conical-shaped washers uas tuaj yeem ua haujlwm siab thaum tswj lawv lub caij nplooj ntoo hlav. Lawv feem ntau yog siv rau hauv cov ntawv thov uas bolt loosening lossis gasket compression yog ib qho kev txhawj xeeb, xws li hauv cov tshuab hnyav.
3. Wave Washers:Wave washers, tseem hu ua lub caij nplooj ntoos hlav ntxhua khaub ncaws, yog tsim los muab lub preload los yog nro rau lub bolted sib koom ua ke. Lawv muaj cov duab nkhaus lossis wavy, uas tso cai rau lawv nqus cov vibrations thiab them nyiaj rau loosening vim thermal expansion. Wave washers feem ntau yog siv rau hauv tsheb, aerospace, thiab kev lag luam.
Hauv kev xaus, cov tshuab ntxhua khaub ncaws yog cov khoom tseem ceeb hauv ntau qhov kev lag luam, thiab lawv lub zog thiab kav ntev sib txawv nyob ntawm cov khoom siv. Hlau ntxhua khaub ncaws, xws li cov hlau tsis muaj steel thiab cov hlau tawv tawv, muaj lub zog siab thiab tiv thaiv corrosion. Rubber thiab yas ntxhua khaub ncaws, xws li neoprene thiab nylon, muab lwm yam zoo xws li rwb thaiv tsev thiab tshuaj tiv thaiv. Lwm hom tshuab ntxhua khaub ncaws, suav nrog fiber ntau, dome, thiab yoj ntxhua khaub ncaws, muaj cov yam ntxwv tshwj xeeb rau cov ntawv thov tshwj xeeb. Thaum xaiv cov tshuab ntxhua khaub ncaws, nws yog ib qho tseem ceeb uas yuav tau xav txog cov kev xav tau ntawm daim ntawv thov thiab xaiv lub tshuab ntxhua khaub ncaws uas tsim nyog uas tuaj yeem tiv taus qhov kev xav tau thiab ib puag ncig.
