Mechanical springs ua kom tag nrho siv lub zog ntawm cov khoom siv, thiab paub lub zog cia thiab kev tso tawm los ntawm txoj kev hloov dua siab tshiab. Cov yam ntxwv ntawm cov khoom txiav txim siab lub cev thiab cov khoom siv dag zog ntawm lub caij nplooj ntoos hlav ntawm cov nroj tsuag mus rau ib qho twg, cuam tshuam cov qauv tsim thiab kev loj hlob ntawm lub caij nplooj ntoos hlav thiab kev txhim kho ntawm cov kev kawm tshwj xeeb. Cov khoom siv uas nquag siv yog cov hlau thiab cov ntaub ntawv tsis-hlau.
Txoj kev loj hlob sai ntawm niaj hnub tshiab khoom ntau yam, tshwj xeeb tshaj yog cov kev tshwm sim tshiab thiab kev txhim kho cov cuab yeej hlau muaj zog tshiab, tau coj mus rau kev ua tau zoo dua; nyob rau tib lub sij hawm, qhov kev pom zoo txuas mus ntxiv ntawm cov txheej txheem tom qab ua raw khoom, xws li cov qauv duab, kev kho cua sov thiab cov dej zoo, thiab lwm yam. Daim ntawv thov thiab kev txhim kho ntawm cov kis tau zoo tuaj yeem ntsib lawv cov kev ua haujlwm thiab ntxiv txhim kho kev nyab xeeb, tiv thaiv yam ntxwv ntawm cov khoom caij nplooj ntoos hlav.
Nyob rau hauv xyoo tas los, nrog rau txoj kev loj hlob sai ntawm cov tshuaj rubber kev lag luam, polyurethane cov ntaub ntawv kuj yog siv los siv rau lub caij nplooj ntoos hlav. Lawv yog siv dav hauv kev co-txo thiab suab nrov-txo cov khoom siv sib txuas. Nitrogen lossis cov pa roj-txias nruab nrab ntawm cov pa cua kuj tseem siv tau rau hauv lub thev plaub. Lub cav loj lub thev naus laus zis, cov khoom siv hluav taws xob, qhov cub kub siab heev thiab lwm hom:
Cov khoom siv uas nquag siv yog cov hlau thiab cov ntaub ntawv tsis zoo:
Feem ntau siv cov khoom hlau xws li caij nplooj ntoos hlav, xim hlau rau cov hlaws, copper alloys rau springs, nickel thiab nickel alloys, elastic alloys rau springs, lwm cov kev sib txuam tshwj xeeb rau springs, thiab nyuam qhuav tsim lub caij nplooj ntoos hlav ultra-pure cav ntoo. Cov khoom siv uas tsis yog xim hlau yog siv xws li: polyurethanes Cov khoom tshwj xeeb xws li roj hmab, roj hmab, yas, cov roj carbon, thiab roj.
