Mufundisi, muitisi mutungamiri anofanirwa kutevedzera neyekuzivikanwa paramita. Semuenzaniso, kana zvaratidzwa pane iyo kabuji ndeye 3 x 2.5, ipapo muConstit Cross chikamu chinofanira kunge chiri 2,5 mm2. Muchokwadi, zvinoitika kuti saizi yakasiyana inogona kusiyana ne 20-30%, uye dzimwe nguva zvimwe. Chii chinotyisidzira? Kufarira kana kuisa kugovera kuzviparadzanisa nemigumisiro yese inotevera. Naizvozvo, usati watenga, zvinodikanwa kuti uwane saizi ye waya yekuona chikamu chichinjika. Nyatsofunga nezve chikamu chemuchinjiko chemaya waya mune diameter uye uchaona zvimwe.
Sei uye sei kuyera iyo diamita ye waya (waya)
Kuyera diamita ye waya, iyo caliper kana micrometer yemhando ipi neipi (mechanic kana yemagetsi) yakakodzera. Zviri nyore kushanda nemagetsi, asi hazvisi zvese. Izvo zvinodikanwa kuyera kurarama zvakanaka pasina kuzviparadzanisa nevamwe, saka kwakatangira-kwakutama kana kubvisa chidimbu chidiki. Izvi zvinogona kuitwa kana mutengesi akatenderwa. Kana zvisiri, tenga chidimbu chidiki chekuedza uye kushandisa zviyero pairi. PaChisimbiso, mufambisi weConstit Conduke, mushure meizvozvo zvinokwanisika kuona iyo chaiyo yekuchinjika-chikamu chewaya pane saizi.
Zviyero zveDhivha yeiyo Wire Micrometer zvakanyatsojeka pane iyo Mechan Caliper
Ndeipi mudziyo wekuyera mune izvi zvirinani? Kana tikataura nezve mimhanzi yemhando, zvino micrometer. Iyo ine chokwadi cheyero pamusoro. Kana tikataura nezve sarudzo dzemagetsi, ipapo nekuda kwezvinangwa zvedu ivo vaviri vanopa zvakavimbika kwazvo.
Kana pasina manyorerwo, kana manyrometer, tora chiScrewdriver uye mutongi. Isu tinofanirwa kuchenesa chidimbu chakanaka chemutungamiriri, saka pasina kutenga test test nguva ino haina kugadzikana. Saka, bvisa chikamu kubva pane chidimbu che waya 5-10 cm. Geza waya pane cylindrical chikamu che screwdriver. Marobhoti anoiswa padyo mumwe kune mumwe, pasina clearance. Zvese zvinotendeuka zvinofanirwa kunge zvakazara, kureva kuti "miswe" yemaroyi inofanira kunge ichirova munzira imwe - kumusoro kana pasi, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso, semuenzaniso.

Kufunga iyo waya waya uchishandisa mutongi
Nhamba yekutendeuka haina kukosha - nezve 10. Izvo zvinogoneka zvakanyanya kana zvishoma, kungozviparadzanisa zviri nyore. Kukanda tendeuka, wobva washandisa iyo inokonzeresa mhepo kumutongi, kuenderana kutanga kwekutanga kwekutanga ne zero zero (seye pikicha). Kuyera kureba kwenzvimbo inogarwa newaya, ipapo inozvitsaura kune nhamba yekutendeuka. Tora iyo waya waya. Izvo zviri nyore.
Semuenzaniso, isu tinofunga kuti saizi ye waya yakaratidzwa mumufananidzo uri pamusoro. Nhamba yekutendeuka mune ino kesi ndeye 11, ivo vanogara 7.5 mm. Isu tinogovera 7.5 kusvika 11, tinowana 0.68 mm. Iyi ichave iyo dhayiyamu yeiyi waya. Tevere, iwe unogona kutsvaga chikamu chemateki uyu.
Tiri kutsvaga chikamu chemafuta mune diameter: formula
Waya mune tambo ine denderedzwa muchikamu chevachinjika. Naizvozvo, pakuverenga, isu tinoshandisa formula yenzvimbo yedenderedzwa. Inogona kuwanikwa uchishandisa radius (hafu yeiyo yakayerwa diamita) kana diameter (ona formula).
Sarudza chikamu chemuchinjiko cheya waya mune diameter: formula
Semuenzaniso, isu tinoverenga nzvimbo yemuchinjiko-chikamu che conductor (waya) muhukuru hwakaverengerwa kare: 0.68 mm. Ngatitangei kushandisa formula ne radius. Kutanga tinowana radius: isu tinopatsanura dhayamu yevaviri. 0.68 mm / 2 = 0.34 mm. Tevere uyu nhamba isu tinotsiva iyo formula
S = π * r2 = 3,14 * 0.342 = 0.36 mm2
Izvo zvinodikanwa kuti uverenge nzira iyi: Kutanga isu tichagadzwa kuita mraba 0.34, ndobva ndawedzera kukosha kwakawanikwa na 3.14. Takatambira chikamu chemuchinjiko cheiyi waya 0.36 mamirimita mamirimita. Iyi yaive waya yakaonda kwazvo, iyo isingashandiswe mune simba network.
Ngativerengei chikamu checabuld chivharo mune diameter tichishandisa chikamu chechipiri chefomula. Izvo zvinofanirwa kunge zviri chaizvo zvazvinoreva. Musiyano unogona kuve mune zviuru zvemazita nekuda kwekutenderera kwakasiyana.
S = π / 4 * D2 = 3.14 / 4 * 0,682 = 0.785 * 0,4624 = 0.36 mm2
Mune ino nyaya, isu tinopatsanura nhamba 3.1414 kusvika ina, isu tichagadzika muzve mativi, iwo maviri manhamba akawanikwa aine mutsauko. Isu tinowana imwe yakakosha, sezvazviri. Iye zvino iwe unoziva nzira yekuona iyo tambo yekuyambuka yemuchinjiko mune diameter. Ndeipi yeaya mafomula yakakunakira iwe, iyo uye kushandisa. Hapana mutsauko.

Maitiro Ekubata Netafura iyi? Semutemo, pamatanda pane chiratidzo kana tag pane iyo maratidziro ayo anoratidzwa paramende. Kune tambo yemaketing, huwandu hwehupenyu hwese uye chikamu chavo chemuchinjiko. Semuenzaniso, kumhanya 2x4. Isu tinofarira iyo parameter yemitsetse. Uye aya manhamba anomira mushure mekunge "x". Mune ino kesi, inotaurwa kuti kune maviri conductor ane muchinjiko-chikamu che4 mm2. Saka isu tichaongorora kuti ruzivo urwu nderechokwadi.
Kuti utarise, kuyera iyo diamita yeimwe yenzira dzakarondedzerwa, wozoreva patafura. Zvinoratidza kuti nechikamu chakadai mune mana mamirimita mamirimita, kukura kwe waya kunofanirwa kunge kuri 2,26 mm. Kana iwe uine zvimwe zvakafanana kana zviyero zvepedyo zviyero (Kuyera kukanganisa kuripo, sezvisina kunaka zviridzwa), zvese zvakanaka, unogona kutenga iyi tambo.
Zvimiro zvakataurwa ndezvekuti zvinogara zvichienderana neicho chaicho.
Asi kazhinji kazhinji iyo chaiyo dhivha yemari inotengesa zvakanyanya zvishoma pane zvakataurwa. Ipapo iwe une nzira mbiri: tsvaga waya yemumwe mugadziri kana kutora chikamu chakakura chevhu. Kwaari, chokwadi, iwe uchafanirwa kupfuura, asi sarudzo yekutanga inoda nguva yakakura, uye kwete chokwadi chekuti iwe uchave unokwanisa kuwana inoenderana inoenderana.

Iyi sarudzo yechipiri inoda mari yakawanda, nekuti mutengo unoenderana zvakanyanya pane yakaziviswa chikamu. Kunyangwe, kwete chokwadi - tambo yakanaka yakaitwa mune zvese zviyero zvinogona kutonyanya kudhura. Izvi zvinonzwisisika - mari yemhangura, uye, kazhinji, uye kuzviparadzanisa nevamwe, nepo tekinoroji nemitemo, yakakura kwazvo. Naizvozvo, vagadziri uye chitryat, vachideredza dhayamita yemiwaya - yekuderedza mutengo. Asi kuchengetedza kwakadaro kunogona kushanduka kuita dambudziko. Saka ita chokwadi chekuyera usati watenga.

Uye zvakare: ongorora uye nekuzvimba kwekupaza. Inofanira kunge yakakora, yakasimba, ine iyo yakaenzana ubvu. Kana, kuwedzera mukuchinja divhiri, dambudziko iri zvakare kuzviparadzanisa - tsvaga tambo yemumwe mugadziri. Kazhinji, zvinokurudzirwa kuwana zvigadzirwa zvinosangana nezvinodiwa zvekuenda, uye kwete kuita izvozvo. Mune ino kesi, pane tariro yekuti tambo kana waya ichashanda kwenguva yakareba uye isina matambudziko. Nhasi hazvisi nyore kuita, asi kana ukaravira wiring mumba kana kubatanidza magetsi kubva post, mhando yacho yakakosha. Naizvozvo, zvinogona kutsvaga.
Maitiro ekuziva chikamu chemuchinjiko we waya yakarongedzwa
Dzimwe nguva inotora inotsanangurwa yakashandiswa - inosanganisira akawanda akafanana akaonda waya. Maitiro ekuverenga chikamu chemuchinjiko cheya waya mune diameter mune iyi nyaya? Ehe, chete.
