Posankha makina katundu: katswiri malangizo

Masiwichi basi (vending makina) amagwiritsidwa ntchito pofuna kudziteteza zimamuchulukira ndi waufupi-dera zikusinthira (CC) olumikizidwa kwa iwo magetsi. Short-dera mu dera baka ichidachi amaperekedwa ndi mu atomu odulidwa wolemera, zimamuchulukira apano - chitetezo matenthedwe. Mu atomu cutoff zinayambitsa yomweyo, matenthedwe chitetezo - patapita kanthawi, zochokera ukulu wa zimamuchulukira zikusinthira (panopa ndi mtengo umene umaposa panopa oveteredwa za makina, anasonyeza mu nyumba yake).

Zinthu mwanzeru

Nthawi zambiri pali kufunika polumikizira zina magetsi (pansi Kutentha, e. Pump ndi T. D.) Mu gulu osiyana (basi). Pankhaniyi n'kofunika kusankha makina katundu. kuwerengetsera pachithunzichi kungachititse kuti kulephera zotiyesa chitetezo mwambo dzidzidzi kapena pafupipafupi disconnection popanda chifukwa. Kusankha makina katundu mawerengedwe zikuphatikizapo mowa watsopano wa zida zikugwirizana. Khalidwe limeneli akhoza kuwapeza deta pasipoti. Ngati bukuli lili okha mowa mphamvu, panopa adzakhala wofanana ndi mphamvu wogawanika pa mlingo voteji (a chosavuta chilinganizo cha kotunga umodzi gawo). Popeza zolembedwa pa imelo. zida panopa zingadziŵike ntchito clamps panopa, kapena imelo. kuyeza chipangizo, mwachidule mphamvu zida pa mphamvu zonse. Tsopano, podziwa mowa panopa zingadziŵike oveteredwa panopa za makina. Iwo anasankha ku mawerengedwe a mowa, koma m'mwamba. Mwachitsanzo, ngati 20, makina adzakhala 25 A.

Mawerengedwe a dera yochepa panopa

Kusankha makina katundu mawerengedwe zikuphatikizapo panopa lalifupi dera. Pakuti kudzipheralo muyezo amafuna chikuperekedwa ena a RS. Chifukwa makina osiyana zimatengera makhalidwe osiyana. zipangizo zamakono zili mu olemba wawo wa makalata: B, C kapena D. B = 5, C = 10, D = 20. chithunzi - ndi koyefishienti kuti zikuchulukireni pa panopa oveteredwa za makina. More chifukwa mtengo ndi kuchulukitsa ndi 1.1 (chitetezo chinthu). Chifukwa, phindu linanena bungwe limene makina ntchito. Mpaka kudziwa mtengo weniweni wa yochepa dera panopa. Pakuti ichi m'pofunika kuyeza ukulu wa impedance kuzungulira "gawo-ziro" nsonga ya kugwirizana kwa zipangizo. Ndiye 220 (voteji mlingo mu volts) kugawidwa ndi phindu kukana izi ndipo inu weniweni yochepa dera panopa. Iwo ayenera kukhala wolingana kapena kukhala wamkulu kuposa yochepa dera tripping makina.

Posankha makina katundu zoletsedwa ndi malamulo a pamwamba, monga ulamuliro, amapereka ntchito yachibadwa chipangizo pamene mwana mafunde zimamuchulukira, komanso kugwira ntchito ngati zimamuchulukira chifukwa wonongeka ya zida zikugwirizana.

Ngati makina kale anapereka ...

Kodi kuwerengera katundu pa makina kuti lilipo kale? Pakuti ichi m'pofunika kudziwa kukula kwa katundu mowa zikusinthira (monga anachita - tafotokozazi). Sitiyenera upambana phindu mwadzina za makina.

Ngati muli ndi vuto, ndipo simungathe kupanga mawerengedwe basi katundu, izo m'pofunika kuti funsani gulu lapadera.
