Posachedwa, tidaganiza zolemba za zingwe ndi mawaya, komabe olembetsa athu anali ndi mafunso ambiri okhudza kudzipatula. Chifukwa chake, m'nkhaniyi, tinaganiza zofotokoza mwatsatanetsatane zingwe zamitundu yolimba ndi mawaya ndi mawaya ndi mawaya. Ganizirani zinthu zowonjezera kwambiri ndikuwonetsa otchuka kwambiri.
Mitundu ya Kuchititsa Osuntha
Poyamba, muyenera kumvetsetsa kuti kusokonekera kwa chinthu chilichonse payekhapayekha, kutengera kapangidwe kake ndi ma netiweki omwe amagwira ntchito. Kutengera izi, mutha kusankha izi:- Crouse, yemwe amagwiritsidwa ntchito pa netiweki yopitilira 700 volts. Adapangidwira kuti azigwiritsa ntchito kunyumba mgawo limodzi kapena gawo la magawo atatu. Ndiye kuti, 2280 ndi 380 volts, motsatana.
- Zingwe zopanda mitambo zomwe zimagwiritsidwa ntchito mu ma network, monga momwe zimakhalira.
- Kwa omwe amachititsa omwe amagwira ntchito nthawi zonse pa 700-1000 volts ndi magetsi osinthika a 220 ndi 400 volts.
- Kwa ochita ndi magetsi mpaka 3,600 volts. AC imapezeka mu izi zimachitika kuyambira 400 mpaka 1800 volts.
- Ndikofunikanso kuwonetsa mawaya omwe amagwiritsidwa ntchito pa voliyumu ya 1000-6000, ndikusinthana tsopano kwa 400-1800 volts.
Ndikofunikanso kuganizira pano:
- Zogwirira ntchito.
- Zolemba ndi magawo ena.
- Gawo la chingwe.
- Chiwerengerocho chinali.
Mitundu ya Kusunga Wire
Monga mukumvetsetsa, kuperewera kumasankhidwa payekha kwa gulu lililonse. Tsopano gawani mitundu yotsatirayi ya mawaya ndi zingwe:
Kukhumudwa kwa mphira
Itha kupangidwa ndi mphira wachilengedwe kapena zopangidwa. Ubwino wa makulidwe oterewa ndi omwe waya umalandira kusinthasintha kwakukulu, komwe kumalola kuti igwiritsidwe ntchito pafupifupi kulikonse. Komabe, kutchinga koteroko sikufanizidwa kuti sizakale, popeza choluka pambuyo pake chimataya katundu. Kutupa koteroko kunalandira chidutswa chotchuka cha chingwe.
Nkhani pamutu: Momwe Mungasankhire Mapangidwe Amkati Oyenera?
Pvc
PVC Kutulutsa kwa mawaya kumadziwika kwambiri. Ubwino Wazikulu Ziyenera Kuperekedwa:
- Mtengo wotsika pakupanga.
- Kutalika kwambiri, komwe kumasungidwa pamatenthedwe otsika.
- Kukana kutentha.
- Katundu wabwino.
Komabe, zovuta zingapo zitha kusiyanitsidwa:
- Popita nthawi, katundu watayika.
- Komanso popita nthawi, kukana kwa mankhwala kwazinthuzo kumachepetsedwa.
Kudzipatula kwa pepala
Pazinthu zamakono zotchinga, zotchinga zoterezi ndizosowa kwambiri, izi zimachitika chifukwa chakuti kulibe mita 35. Komabe, ngati pepalalo likugwiritsidwa ntchito mu chingwe champhamvu mphamvu, ndiye opanga gwiritsani ntchito mobwerezabwereza, zomwe zimaphatikizapo mafuta, rosin ndi sera.
Ngati timalankhula za zovuta, ndizofunikira, chifukwa pepalalo silingathetse zakunja. Chifukwa chake, omwe adatsogolera ku satha kupezeka kawirikawiri, mutha kuwakhazikitsanso zipinda zouma zokha.
Ma fluoroplast
Mawaya a fluoroplast a mawaya ndi zingwe amadziwika kuti ndi amodzi mwa odalirika. Komabe, njira yogwiritsira ntchito izi imawoneka ngati ovuta. Kupatula apo, seluoring woyamba ndilanduke pamitsempha yakhome, ndiye kuti imayambika kuphika kutentha kwambiri. Zotsatira zake ndi kutchinjiriza, zomwe ndizovuta kuwonongeka.
