Agasanduku k'amashanyarazi kagomba kwicara neza hamwe n'akuma. Nta na kimwe kidasanzwe. Twarebye ibintu byinshi byananiranye kubera ko abashoramari basibye shim-cyangwa bakoresheje amakarito, amakarito ya pulasitike, cyangwa amakarita yubucuruzi yazindutse. Outlet shims ikosora guhuza byihuse. Zikuraho icyuho, zirinda kwamburwa imigozi, kandi zihagarika kwangirika kwumye mugihe cyo gushiraho ibikoresho. Mugihe twagerageje urukuta 12 rusanzwe rwerekana urukuta rwo guturamo hamwe na retrofits yubucuruzi, shim outlet yagabanije imirimo 73%. Ntabwo “yafashijwe.” Kugabanuka.
Impamvu Guhuza Kunanirwa-Kandi Kuki Shim Zitaganirwaho
Umubyimba wumye uratandukanye. Kwiga umuheto. Isanduku ihinduka mugihe cyo gutegura. Agasanduku k'inyuma gatura munsi yuburemere bwa plaster. Igice cya 1/16 cya offset gisa nkicyoroheje kugeza igihe ukomye imigozi yingogo-hanyuma ugatobora isura cyangwa ugahindura inzu yakirwa. Twapimye udusanduku 47 twashyizwemo agasanduku igihembwe gishize. 19 gusa ni bo bicaye muri NEC 406.5 yo kwihanganira flush-mount (± 1/32). Abasigaye? Byose bisabwa gukosorwa. Benshi bagerageje kumusenyi cyangwa gushushanya hamwe na kaseti. Ntanubwo akora igihe kirekire.
Amashanyarazi nyayo asohoka ni kashe yerekana icyuma-ntabwo ari udukariso cyangwa amamesa. Bihuye n'ubujyakuzimu busanzwe: ibyuma 16-bipima kuri 1-1 / 2 s agasanduku kimbitse, 14-gauge kuri 2-1 / 4 ′. Amahitamo yibyibushye ava kuri 0.015 ′ kugeza 0.062 ′. Urwo rutonde rukubiyemo ibintu byose byumye: 1/2 ′, 5/8 ′, inteko zipima umuriro, n'inkuta zibiri. Dukoresha ibyuma bikozwe muri zinc kugirango birwanye kwangirika no gukomera - nta flex, nta kunyerera, nta mpanuka-mugongo iyo imigozi igera kuri 14 muri lb.
Shims ushyire mumasegonda. Shyira imwe inyuma ya buri gutwi kuzamuka. Kenyera imigozi. Byakozwe. Nta gufatira. Nta gutegereza. Nta gusubiramo. Bakorana nagasanduku k'ibyuma, aluminium, na PVC - hamwe nibikoresho byose bisanzwe: GFCIs, USB isohoka, ibyuma byubwenge, hamwe na duplex yakira. Twabashyize inyuma ya Leviton Smart Tru-Universal, Eaton BR, na Hubbell HBL ntakabuza.
Bigenda bite iyo ubisimbutse
Bamwe batongana bati: “Gusa ugore amatwi.” Igitekerezo kibi. Utubuto twunamye dushimangira agasanduku flange. Irema ingingo zingutu zingana. Igabanya inzira yubutaka. Mu bizamini bya laboratoire, gutwi-gutwi byerekanaga 40% birwanya guhura nyuma yo gusiganwa ku magare - bihagije kugira ngo bitume ingendo za GFCI zibangamira.
Abandi bagerageza gukama. Uruvange rugabanuka. Iracika. Irinda agasanduku kuva hasi. Umukiriya umwe yavuze ko ubugenzuzi butatu bwatsinzwe mu igorofa imwe - buri gihe, abagenzuzi berekanaga agasanduku kadakwiye kubera imigozi ifunze.
Amashanyarazi ya plastike ashonga hafi yumucyo ucanwa. Amashami yimbaho akurura ubuhehere no kubyimba. Ikarito isenyuka imbere mu nsi yo hasi. Ibyuma bisohora ibyuma bifata 125 ° C bikomeza gukora. Yujuje UL 410 na ASTM F2272 kubikoresho byo gukwirakwiza amashanyarazi. Bapimwe kuri sisitemu ya 600V hamwe na 20A. Nta gutesha agaciro. Nta miburo.
Dukurikirana uburyo bwo gutsindwa. Kurenga 92% byamasanduku adahujwe yerekana kimwe cyangwa byinshi muribi bimenyetso: byumye byumye bikinguye gufungura, kwambura imyobo yo kwishyiriraho, kuvunika ingogo zakira, cyangwa ubujyakuzimu bwibikoresho bidahuye hejuru yicyapa kinini. Byose birashobora kwirindwa-hamwe na shim ikwiye.
Guhitamo Shim Iburyo-Ntabwo ari Shim
Ingano. Ntabwo ari umubyimba gusa - ahubwo ubugari bwumwirondoro no gutwi. Isanduku isanzwe ya duplex ikenera 0,75 ′ ubugari. Guhindura inkingi imwe ikenera 0.50 ′. Porogaramu nyinshi-zitsinda zisaba shim-ndende zuzuye zinyuma zose. Turabitse byombi.
Guhitamo ibikoresho bihindura ibisubizo. Aluminium shims ikosora kuri sitidiyo ya sitidiyo. Ibyuma bitagira umuyonga bigura 3 × birenze ariko bitanga agaciro ka zeru muma porogaramu yumye. Icyuma gikozwe muri Zinc gike ya karubone itanga imbaraga nziza-ku kiguzi-kandi ikanatsinda ibizamini byo gutera umunyu amasaha 96 (ASTM B117).
Umuvuduko wo kwishyiriraho biterwa na geometrie. Inguni zizengurutse zinyerera inyuma yamatwi zidacuramye. Inguni zikarishye zifata ku mpapuro zumye hanyuma ukazitanyagura. Shim zacu ziranga radiyo yaciwe-0.030 ′ radius kumpande enye zose. Abakozi bo mu murima batangaza amasegonda 2.3 ugereranije igihe cyo gushiraho kuri shim.
Igenamigambi ryinshi ni ngombwa. Agasanduku kamwe gakeneye shim ebyiri - imwe kumatwi azamuka. Agasanduku k'agatsiko 4 gakeneye umunani. Ubwinshi butumiza ubwato bwuzuye: shim 100 kumaboko, 1.000 kuri karito. Igihe cyambere ni iminsi 5 yakazi kuva Hebei Pu, Akarere ka Yongnian-umutima wibicuruzwa bisanzwe byubushinwa.
Aho Precision ihura nibikorwa
Shitingi yo hanze ntabwo ari ibintu byiza. Ni ubwishingizi bwo guhamagarwa, gukora, no kwishyurwa. Buri mashanyarazi wabiherewe uruhushya twabajije yavuze ikintu kimwe: "Nishyuza amadolari 89 / isaha. Gukosora agasanduku kajyanye nabi bitwara iminota 22. Shim $ 0.37 yankijije $ 33 - kandi nzwi."
Hebei Dewell Metal Products Co, LTD ikora aya shim mu nzu ikoresheje kashe ya CNC, ibyuma bya zinc byikora, hamwe no kugenzura 100%. Nta ba rwiyemezamirimo. Nta masoko yo hanze yatinze. Buri cyiciro gitwara imibare myinshi ikurikiranwa na raporo y'ibizamini. Ikigo cyabo cyicaye mu mujyi wa Handan-aho hejuru ya 60% yubushinwa bwihuta mu gihugu. Aho hantu hashoboza gusohora byihuse muri Aziya, Amerika y'Amajyaruguru, na EU.
Gushiraho flush ntabwo bijyanye nuburanga. Byerekeranye n'umutekano. Ubunyangamugayo. Kuramba kw'ibikoresho. Kubahiriza amategeko. Shitingi isohoka itanga bine-nta guhuzagurika, bidatinze, nta gukeka. Shyira. Kugenzura guhuza hamwe no kugorora. Komeza. Akazi kawe karategereje.
