Lamba wonyamulira katundu ndi gawo lofunika kwambiri la makina onyamulira katundu, omwe amagwiritsidwa ntchito kunyamula zinthu ndikuzinyamula kupita nazo kumalo osankhidwa. M'lifupi ndi kutalika kwake zimadalira kapangidwe ndi kapangidwe kake koyamba.chonyamulira lamba.
01. Kugawa lamba wonyamula katundu
Zipangizo zodziwika bwino za lamba wonyamula katundu zitha kugawidwa m'magulu awiri: chimodzi ndi chingwe cha waya chachitsulo, chomwe chili ndi mphamvu yolimba yonyamula katundu komanso katundu wabwino wakuthupi komanso wamakaniko, kotero chimatha kukwaniritsa kufunikira kwa mayendedwe othamanga kwambiri pansi pa maziko a mphamvu yayikulu yonyamula katundu; Mtundu wachiwiri ndi nayiloni, thonje, rabala ndi zipangizo zina, zomwe ndizochepa pang'ono poyerekeza ndi kuchuluka kwa mayendedwe ndi liwiro la chingwe cha waya chachitsulo.
02. Kodi mungasankhe bwanji lamba woyenera wonyamulira katundu?
Kusankhidwa kwalamba wonyamulira katunduKutengera kutalika kwa chonyamulira, mphamvu yonyamulira, kupsinjika kwa lamba, mawonekedwe a zinthu zonyamulira, momwe zinthu zimalandirira, komanso malo ogwirira ntchito.
Kusankha lamba wonyamulira katundu kuyenera kukwaniritsa zofunikira izi:
Lamba wonyamulira wa nsalu ya polyester uyenera kusankhidwa kuti ugwiritsidwe ntchito pa lamba wonyamulira waufupi. Kwa lamba wonyamulira wokhala ndi mphamvu zambiri zonyamulira, mtunda wautali, kutalika kwakukulu konyamulira komanso mphamvu yayikulu, lamba wonyamulira wa chingwe chachitsulo uyenera kusankhidwa.
Zipangizo zonyamulidwa zimakhala ndi zinthu zotchinga zazikulu, ndipo pamene kutsika kwachindunji kwa malo olandirira kuli kwakukulu, chonyamuliracho cholimba komanso chosagwa chiyenera kusankhidwa.
Chiwerengero chachikulu cha zigawo za lamba wonyamulira nsalu wopangidwa ndi zigawo ziwiri sichiyenera kupitirira zigawo 6: pamene zinthu zonyamulira zili ndi zofunikira zapadera pa makulidwe a lamba wonyamulira, zimatha kuwonjezeredwa moyenera.
Chonyamulira lamba cha pansi pa nthaka chiyenera kukhala choletsa moto.
Cholumikizira cha lamba wonyamulira
Mtundu wolumikizirana wa lamba wotumizira katundu uyenera kusankhidwa malinga ndi mtundu wa lamba wotumizira katundu ndi makhalidwe a lamba wotumizira katundu:
Lamba wonyamulira chingwe chachitsulo ayenera kugwiritsa ntchito cholumikizira chovunda;
Cholumikizira chovunda chiyenera kugwiritsidwa ntchito ngati lamba wonyamulira nsalu wokhala ndi zigawo zambiri;
Cholumikizira chomatira kapena cholumikizira chamakina chiyenera kugwiritsidwa ntchito pa lamba wonyamulira nsalu yonse.
Mtundu wa cholumikizira cha vulcanization cha lamba wotumizira: lamba wotumizira wa nsalu yolumikizidwa ayenera kugwiritsa ntchito cholumikizira cholowera; lamba wotumizira wa chingwe chachitsulo amatha kugwiritsa ntchito cholumikizira chimodzi kapena zingapo zolumikizidwa molingana ndi mtundu wa mphamvu yokoka.
Chitetezo cha lamba wonyamula katundu
Chitetezo cha lamba wonyamula katundu chiyenera kusankhidwa malinga ndi mikhalidwe yosiyanasiyana: mwachitsanzo, kwa lamba wamba, chitetezo cha lamba wonyamula katundu wa waya chikhoza kukhala 7-9; Pamene wonyamula katunduyo ayamba kuyenda bwino, kuyeza mabuleki, 5-7 ziyenera kusankhidwa.
03. Kodi mungasankhe bwanji bandwidth ndi liwiro?
1. Bandwidth
Kawirikawiri, pa liwiro la lamba, mphamvu yonyamulira ya lamba imawonjezeka ndi kukula kwa lamba. Lamba wonyamulira ayenera kukhala wokulirapo mokwanira kuti mabuloko akuluakulu a block yonyamulidwa ndi ufa wosakaniza asaikidwe pafupi ndi m'mphepete mwa lamba wonyamulira, ndipo kukula kwa mkati mwa chute yodyetsera ndi mtunda pakati pa chute yotsogolera ziyenera kukhala zokwanira kuti chisakanizo cha tinthu tating'onoting'ono tosiyanasiyana chidutse popanda kutsekeka.
2. Liwiro la lamba
Liwiro loyenera lamba limadalira kwambiri mtundu wa zinthu zomwe ziyenera kunyamulidwa, mphamvu yonyamulira yofunikira komanso mphamvu ya lamba yomwe imagwiritsidwa ntchito.
Zinthu zotsatirazi ziyenera kuganiziridwa posankha liwiro la lamba:
Bandwidth: kukula kwa tepi kukakhala kochepa, kumakhala kosakhazikika kwambiri mukathamanga mofulumira, komanso kumakhala kosavuta kufalikira kwambiri.
Chonyamulira chokhazikika: nthawi zambiri, khalidwe loyika ndi lalikulu, ndipo liwiro la lamba ndilabwino kwambiri, pomwe liwiro la zonyamulira zokhazikika komanso zoyenda ndi lotsika.
Potumiza mopingasa kapena mopingasa, liwiro likhoza kukhala lalikulu. Pamene kupendekeka kuli kwakukulu, zinthuzo zimakhala zosavuta kuzunguliza kapena kutsetsereka, ndipo liwiro lotsika liyenera kugwiritsidwa ntchito.
Chonyamulira lamba chokhala ndi kukhazikika kopendekera: mwachidule, chonyamulira lamba chotsika chiyenera kukhala ndi liwiro lotsika, chifukwa zipangizozo zimakhala zosavuta kupukutira ndikutsetsereka pa lamba panthawi yonyamulira pansi.
Mphamvu yonyamulira katundu ikachuluka kwambiri, mphamvu ya lamba imafunika. Pofuna kuchepetsa mphamvu ya lamba, liwiro lalikulu lingagwiritsidwe ntchito.
Kupindika kwa lamba pa chopukutira: kugwedezeka kwa katundu ndi kugwedezeka kwa zinthu zimayambitsa kusweka kwa lamba, kotero ndi bwino kuchepetsa liwiro la chopukutira cha mtunda waufupi. Komabe, kuti achepetse kupsinjika kwa lamba, zopukutira za mtunda wautali nthawi zambiri zimagwiritsa ntchito liwiro lalikulu.
Chonyamulira lamba chimatha kumaliza mphamvu yonyamulira yomwe ikufunika ndi dongosololi, yomwe imadalira kwambiri kukula kwa lamba ndi liwiro la lamba. Kuthamanga kwa lamba kumakhudza kwambiri kukula kwa lamba, kulemera kofooka, mtengo ndi khalidwe la ntchito ya chonyamulira lamba. Pansi pa mphamvu yonyamulira yomweyi, njira ziwiri zitha kusankhidwa: bandwidth yayikulu ndi liwiro lotsika la lamba, kapena bandwidth yaying'ono ndi liwiro lalikulu la lamba. Zinthu zotsatirazi ziyenera kuganiziridwa posankha liwiro la lamba:
Makhalidwe ndi zofunikira pa njira yogwiritsira ntchito zinthu zoperekedwa
(1) Pa zinthu zomwe zimakhala ndi mphamvu zochepa komanso tinthu tating'onoting'ono, monga malasha, tirigu, mchenga, ndi zina zotero, liwiro lalikulu liyenera kugwiritsidwa ntchito (nthawi zambiri 2 ~ 4m/s).
(2) Pa zinthu zomwe zimakhala ndi mphamvu zambiri, mabuloko akuluakulu komanso mantha ophwanyidwa, monga malasha akuluakulu, miyala ikuluikulu, coke, ndi zina zotero, liwiro lotsika (mkati mwa 1.25 ~ 2m/s) limalimbikitsidwa.
(3) Pa zinthu zonga ufa kapena zinthu zokhala ndi fumbi lochuluka zomwe zimakhala zosavuta kukweza fumbi, liwiro lotsika (≤ 1.0m/s) liyenera kugwiritsidwa ntchito kuti fumbi lisawuluke.
(4) Pa katundu, zinthu zosavuta kuzizungulira kapena malo omwe ali ndi zofunikira kwambiri pa thanzi la chilengedwe, liwiro lotsika (≤1.25m/s) ndiloyenera.
Kapangidwe ndi kachitidwe kotulutsira lamba
(1) Ma conveyor a lamba ataliatali komanso opingasa amatha kusankha liwiro la lamba lokwera.
(2) Kwa ma conveyor a lamba omwe ali ndi kutalika kwakukulu kapena mtunda waufupi wotumizira, liwiro la lamba liyenera kuchepetsedwa moyenera.
(3) Pamene trolley yotulutsira katundu ikugwiritsidwa ntchito potulutsira katundu, liwiro la lamba siliyenera kukhala lalikulu kwambiri, nthawi zambiri siliyenera kupitirira 3.15m/s, chifukwa kupendekera kwenikweni kwa lamba wonyamula katundu mu trolley yotulutsira katundu ndi kwakukulu.
(4) Pamene chotsitsa pulawo chikugwiritsidwa ntchito potulutsa mphamvu, liwiro la lamba siliyenera kupitirira 2.8m/s chifukwa cha kukana kowonjezereka ndi kuwonongeka.
(5) Liwiro la lamba la chonyamulira lamba chotsika pansi chomwe chili ndi malo otsetsereka kwambiri sichiyenera kupitirira 3.15m/s.
Lamba wonyamulira katundu ndiye gawo lalikulu la chonyamulira katundu, chomwe ndi gawo lonyamulira katundu komanso gawo lokoka katundu. Mtengo wa lamba wonyamulira katundu mu chonyamulira katundu ndi 30% - 50% ya ndalama zonse zomwe zimagwiritsidwa ntchito. Chifukwa chake, pa lamba wonyamulira katundu, chisamaliro chiyenera kuperekedwa pakusankha zipangizo, liwiro la lamba ndi kukula kwa lamba kuti zitsimikizire kuti chonyamuliracho chikugwira ntchito bwino komanso mokhazikika.
