Chachitatu ndi ndondomeko ya mapangidwe a fuse.
Chachinayi chikuyimira mphamvu ya fuseyi.
Awiri, gulu la fuse
Malinga ndi kapangidwe kake, ma fuse amatha kugawidwa m'magulu atatu: mtundu wotseguka, mtundu wotsekedwa ndi mtundu wotsekedwa.
1. Tsegulani fusesi yamtundu
Pamene kusungunula sikuletsa arc lawi ndi zitsulo kusungunuka particles ejection chipangizo, okha oyenera kumasuka yochepa dera panopa si nthawi yaikulu, fusesi izi nthawi zambiri ntchito osakaniza mpeni lophimba.
2. Semi-otsekeredwa fusesi
Fuseyi imayikidwa mu chubu, ndipo mbali imodzi kapena zonse za chubu zimatsegulidwa.Fuseyo ikasungunuka, moto wa arc ndi zitsulo zosungunula zitsulo zimatulutsidwa kumbali ina, zomwe zimachepetsa kuvulala kwina kwa ogwira ntchito, koma zimakhalabe zotetezeka mokwanira ndipo kugwiritsa ntchito kumakhala kochepa kwambiri.
3. Fuse yotsekedwa
Fuseyi imatsekedwa kwathunthu mu chipolopolo, popanda arc ejection, ndipo sichingabweretse ngozi ku mbali yapafupi yowuluka ndi ogwira ntchito pafupi.
Chachitatu, mawonekedwe a fuse
Fuseyi imapangidwa makamaka ndi kusungunula ndi fuse chubu kapena fuse chofukizira chimene kusungunula anaika.
1.Sungunulani ndi gawo lofunikira la fusesi, lomwe nthawi zambiri limapangidwa kukhala silika kapena pepala.Pali mitundu iwiri ya zida zosungunuka, imodzi ndi zida zotsika zosungunuka, monga lead, zinki, malata ndi aloyi ya tin-lead;Zina ndi zida zosungunuka kwambiri, monga siliva ndi mkuwa.
2.The melt chubu ndi chipolopolo chotetezera cha kusungunula, ndipo chimakhala ndi zotsatira zozimitsa arc pamene kusungunuka kumasakanikirana.
Zinayi, magawo a fuse
Magawo a fusesi amatanthawuza magawo a fuse kapena chosungira fusesi, osati magawo a kusungunuka.
1. Sungunulani magawo
Kusungunuka kuli ndi magawo awiri, ovotera panopa ndi fusing current.Zovoteledwa panopa zimatanthawuza mtengo wamakono womwe umadutsa mu fuse kwa nthawi yaitali popanda kusweka.Fuse yamakono nthawi zambiri imakhala yowirikiza kawiri kuposa yapano, nthawi zambiri kudzera muzitsulo zosungunula ndi 1.3 nthawi yomwe idavotera panopa, iyenera kusakanikirana mu ola limodzi;Nthawi 1.6, iyenera kusakanikirana mkati mwa ola limodzi;Fuseyi ikafika, fuseyo imasweka pambuyo pa masekondi 30 ~ 40;Pamene 9 ~ 10 nthawi yomwe adavotera ifikira, kusungunuka kuyenera kusweka nthawi yomweyo.Kusungunula kumakhala ndi chitetezo cha nthawi yosinthika, kukulirapo komwe kumadutsa muzitsulo, kumachepetsa nthawi yosakanikirana.
2. Zowotcherera zitoliro magawo
Fuseyi ili ndi magawo atatu, omwe ndi magetsi ovotera, ovotera panopa komanso odulidwa.
1) Magetsi ovotera amaperekedwa kuchokera ku Angle of arc kuzimitsa.Pamene mphamvu yogwira ntchito ya fuseyi ndi yaikulu kuposa magetsi ovotera, pangakhale ngozi kuti arc sangathe kuzimitsidwa pamene kusungunuka kwasweka.
2) Chiyembekezo chamakono cha chubu chosungunuka ndi mtengo wamakono womwe umatsimikiziridwa ndi kutentha kovomerezeka kwa chubu chosungunuka kwa nthawi yaitali, kotero chubu chosungunuka chikhoza kudzazidwa ndi magulu osiyanasiyana amakono ovekedwa, koma machubu osungunuka amatha. asakhale wamkulu kuposa momwe adavotera pachubu chosungunuka.
3) Kudulira kwamphamvu ndiye kuchuluka kwapano komwe kumatha kudulidwa fuseyo ikachotsedwa ku vuto la dera pamagetsi ovotera.
Chachisanu, mfundo yogwira ntchito ya fusesi
Njira yophatikizira fuseyi imagawidwa m'magawo anayi:
1. Kusungunula kuli mndandanda mu dera, ndipo katundu wamakono akuyenda kupyolera mu kusungunuka.Chifukwa cha kutentha kwa panopa kumapangitsa kuti kutentha kusungunuke kukwera, pamene dera lodzaza kapena chigawo chachifupi chikachitika, kuwonjezereka kwaposachedwa kapena kwanthawi yayitali kumapangitsa kusungunula kutentha kwambiri ndikufikira kutentha kosungunuka.Kukwera kwamakono, kutentha kumakwera mofulumira.
2. Chisungunukocho chidzasungunuka ndikusintha kukhala nthunzi wachitsulo chikafika pa kutentha kosungunuka.Kukwera kwamakono, kumachepetsa nthawi yosungunuka.
3. Nthawi yomwe kusungunula kusungunuka, pamakhala phokoso laling'ono la kusungunula m'derali, ndipo zamakono zimasokonezedwa mwadzidzidzi.Koma kusiyana kwakung'ono kumeneku kumaphwanyidwa nthawi yomweyo ndi magetsi ozungulira, ndipo arc yamagetsi imapangidwa, yomwe imagwirizanitsa dera.
4. Pambuyo pa arc, ngati mphamvu ikuchepa, idzadzimitsa yokha ndi kufalikira kwa kusiyana kwa fuse, koma iyenera kudalira miyeso yozimitsira fuse pamene mphamvu ndi yaikulu.Pofuna kuchepetsa nthawi yozimitsa arc ndikuwonjezera mphamvu yosweka, ma fuse akuluakulu amakhala ndi njira zozimitsa bwino za arc.Kuchuluka kwa mphamvu yozimitsa ya arc ndiko, kuthamanga kwa arc kumazimitsidwa, ndipo kukulirapo kwaposachedwa kwafupipafupi kumatha kusweka ndi fusesi.
Chachisanu ndi chimodzi, kusankha fusesi
1. Sankhani ma fuse okhala ndi milingo yofananira yamagetsi malinga ndi mphamvu yamagetsi;
2. Sankhani ma fuse omwe ali ndi mphamvu yosweka molingana ndi vuto lalikulu lomwe lingachitike pamagawo ogawa;
3, fuyusi mu dera lamagetsi lachitetezo chachifupi, kuti mupewe injini poyambitsa fuyusi, pagalimoto imodzi, kuchuluka kwamafuta osungunuka kuyenera kukhala kosachepera 1.5 ~ 2.5 nthawi yomwe idavotera pano. za motere;Kwa ma motors angapo, kuchuluka kwa kusungunuka kwanthawi yayitali sikuyenera kuchepera 1.5 ~ 2.5 nthawi yomwe idavoteledwa ndi mphamvu yayikulu yamagetsi kuphatikiza kuchuluka komwe kuwerengeredwa pamagalimoto ena onse.
4. Pachitetezo chachidule cha kuyatsa kapena ng'anjo yamagetsi ndi katundu wina, kusungunula komweku kumayenera kukhala kofanana kapena kukulirapo pang'ono kuposa kuchuluka kwa katundu.
5. Mukamagwiritsa ntchito fuse kuti muteteze mizere, ma fuse ayenera kuikidwa pamzere uliwonse.Ndi zoletsedwa kukhazikitsa fuse pa mzere ndale mu magawo awiri waya atatu kapena atatu gawo anayi waya dera, chifukwa ndale mzere yopuma kungachititse voteji kusamvana, amene akhoza kutentha zida zamagetsi.Pamizere ya gawo limodzi loperekedwa ndi gululi, ma fuse ayenera kuyikidwa pamizere yopanda ndale, osaphatikiza ma fuse onse a gridi.
6. Miyezo yonse ya fusesi iyenera kugwirizana wina ndi mzake ikagwiritsidwa ntchito, ndipo mphamvu yosungunuka yamadzimadzi iyenera kukhala yaying'ono kusiyana ndi yapamwamba.
