Njira zoyezera mphamvu zamagetsi ndizofunikira pafupifupi m'mafakitale onse, malonda ndi malonda. Popeza maselo onyamula katundu ndi zigawo zofunika kwambiri za machitidwe oyesera mphamvu, ayenera kukhala olondola ndikugwira ntchito moyenera nthawi zonse. Kaya monga gawo lokonzekera kukonza kapena poyankha kutha kwa ntchito, kudziwa kuyesa akatundu cellzingathandize kupanga zisankho zodziwitsidwa za kukonza kapena kusintha zinthu zina.
Chifukwa chiyani ma cell cell amalephera?
Maselo a katundu amagwira ntchito poyesa mphamvu yomwe ikugwiritsidwa ntchito pa iwo ndi siginecha yamagetsi yotumizidwa kuchokera kugwero lamagetsi loyendetsedwa bwino. Chida chowongolera, monga chokulirakulira kapena chowongolera kupsinjika, kenako chimasintha siginecha kukhala mtengo wosavuta kuwerenga pa chowonetsera cha digito. Ayenera kuchita pafupifupi malo aliwonse, omwe nthawi zina angayambitse zovuta zambiri pakugwira ntchito kwawo.
Mavutowa amapangitsa kuti maselo olemetsa alephereke ndipo, nthawi zina, amatha kukumana ndi zovuta zomwe zimakhudza momwe amagwirira ntchito. Ngati kulephera kukuchitika, ndi bwino kuyang'ana kukhulupirika kwa dongosolo kaye. Mwachitsanzo, si zachilendo kuti mamba achulukidwe ndi mphamvu. Kuchita zimenezi kukhoza kusokoneza selo yonyamula katundu ndipo ngakhale kuchititsa kuti anthu azinjenjemera. Kukwera kwamphamvu kumathanso kuwononga ma cell olemetsa, monga momwe chinyezi chilichonse kapena kutayikira kwamankhwala kumalowera pamlingo.
Zizindikiro zodalirika za kulephera kwa cell cell ndi:
Sikelo/chipangizo sichidzakonzanso kapena kuwongolera
Kuwerenga kosagwirizana kapena kosadalirika
Kulemera kosawerengeka kapena kupsinjika
Kusuntha mosasintha paziro bwino
sanawerenge nkomwe
Kuthetsa Mavuto a Maselo:
Ngati dongosolo lanu likuyenda molakwika, fufuzani ngati pali zopunduka zakuthupi. Chotsani zifukwa zina zodziwikiratu za kulephera kwa dongosolo - zingwe zolumikizirana zoduka, mawaya otayirira, kuyika kapena kulumikizana ndi mapanelo owonetsa kukangana, ndi zina zambiri.
Ngati kulephera kwa cell cell kukuchitikabe, njira zingapo zothetsera mavuto ziyenera kuchitidwa.
Ndi DMM yodalirika, yapamwamba komanso siginecha ya manambala 4.5, mudzatha kuyesa:
zero balance
Insulation resistance
mlatho umphumphu
Pomwe chomwe chalephereka chadziwika, gulu lanu litha kusankha momwe lingapitirire patsogolo.
Zero balansi:
Kuyezetsa kwa zero kungathandize kudziwa ngati selo yonyamula katundu yawonongeka, monga kulemetsa, kugwedeza, kapena kuvala zitsulo kapena kutopa. Onetsetsani kuti cell yolemetsa "palibe katundu" musanayambe. Kuwerengera kwa zero kukakhala kuwonetsedwa, lumikizani malo olowetsa ma cell cell ku chisangalalo kapena voteji. Yezerani voteji ndi millivoltmeter. Gawani zowerengera ndi mphamvu yolowera kapena yosangalatsa kuti muwerenge ziro mu mV/V. Kuwerenga uku kuyenera kufanana ndi chiphaso choyambirira choyezera ma cell kapena pepala lazogulitsa. Ngati sichoncho, cell cell ndi yoyipa.
Insulation resistance:
Kukaniza kwa insulation kumayesedwa pakati pa chingwe chishango ndi gawo la cell cell. Pambuyo pochotsa selo yonyamula katundu kuchokera ku bokosi lolumikizirana, gwirizanitsani zotsogolera zonse pamodzi - kulowetsa ndi kutulutsa. Yezerani kukana kwa kutchinjiriza ndi megohmmeter, kuyeza kukana kwa kutchinjiriza pakati pa waya wolumikizidwa wolumikizidwa ndi cell cell body, ndiye chishango cha chingwe, ndipo pomaliza kukana kukana pakati pa cell cell ndi chishango cha chingwe. Kuwerengera kwa insulation resistance kuyenera kukhala 5000 MΩ kapena kukulirapo pamlatho-to-case, chishango cha mlatho-ku-chingwe, ndi chishango cha case-to-cable, motsatana. Makhalidwe otsika amawonetsa kutayikira komwe kumachitika chifukwa cha chinyezi kapena dzimbiri lamankhwala, ndipo kutsika kwambiri ndi chizindikiro chotsimikizika cha kulowerera kwakanthawi kochepa, osati chinyezi.
Bridge Integrity:
Kukhulupirika kwa mlatho kumayang'ana zolowetsa ndi zotulutsa ndikuyesa ndi ohmmeter pagawo lililonse lazolowera ndi zotuluka. Pogwiritsa ntchito zidziwitso zoyambilira, yerekezerani zolowetsa ndi zotulutsa kuchokera ku "negative output" mpaka "negative input", ndi "negative output" mpaka "plus input". Kusiyana pakati pa zikhalidwe ziwirizi kuyenera kukhala kochepa kapena kofanana ndi 5 Ω. Ngati sichoncho, pakhoza kukhala waya wosweka kapena wofupikitsidwa chifukwa cha kugwedezeka, kugwedezeka, kuphulika, kapena kutentha kwambiri.
Impact resistance:
Maselo onyamula ayenera kulumikizidwa ku gwero lamphamvu lokhazikika. Kenako, pogwiritsa ntchito voltmeter, gwirizanitsani ndi zotuluka kapena ma terminals. Samalani, kanikizani maselo onyamula katundu kapena zodzigudubuza kuti muwonetse kugwedezeka pang'ono, kusamala kuti musagwiritse ntchito katundu wambiri. Yang'anani kukhazikika kwa kuwerenga ndikubwereranso ku kuwerenga koyambirira kwa ziro. Ngati kuwerengako sikunayende bwino, kungasonyeze kuti kulumikizidwa kwa magetsi kwalephera kapena kutha kwa magetsi kungawononge mgwirizano pakati pa strain gauge ndi chigawocho.
