Sithetha malunga neempawu zoyilo zenkqubo yokuphononongwa kunye nokucebisa, indlela yokwenza ngokuchanekileyo.
Yintoni eyenza inkqubo yokuqalisa
Ngolwakhiwo, umhlaba unomxholo osingqongileyo (isekelo lokufumana umhlaba), itayara yokuthoba kunye nokudibanisa umqhubi wabo. Njengearhente yomhlaba, i-pins yensimbi ihlala isetyenziswa, okanye ihlawulwe emhlabeni ukuze ukuxhathisa komhlaba kungaphantsi kwe-boiler ye-220 v ngaphandle kwe-10 ohms-ukuba ikhona). Inkanyazelwa iqhotyoshelwe ngumqhubi wokudibanisa ngebhanti yokuqhubela phambili kwiphaneli yokuqhuba eqhotyoshelweyo iqhotyoshelwe kuyo (i-wire idla ngokuhlala yedwa etyhefu ngombala ophuzi-eluhlaza).
Imisebenzi esisiseko yendlu yabucala
Unxibelelwano lwezinto zenethiwekhi yombane ukusuka emhlabeni zikuvumela ukuba ukhusela abasebenzisi kumothuso wombane kunye nezixhobo zombane okanye iimpazamo zombane. Izizathu ezinyanzelekileyo zenziwa kwizakhiwo zanamhlanje, kunye nakwezinye iimeko esele zikwizakhiwo ezizodwa (umzekelo, ngaphandle kwenkonzo yegesi, ukuba impompo yegesi ifakiwe kwikhiti okanye enye izixhobo zondla kwi-mains).Ungayenza njani inkqubo ngokuchanekileyo
Owona msebenzi uphambili xa isixhobo somhlaba simiselwe ngokuchanekileyo ziiparamitha zesekethe - ubude bobude bokuba ngaba abaqhubi, kuya kufuneka bathathe inani leentolo ezithe nkqo okanye ezithe nkqo ukuqinisekisa ukuvuza okusebenzayo. Kuxhomekeka kwiimpawu zomhlaba, ezibizwa ngokuba kukunganyangeki komhlaba. Ixabiso eliphantsi, ubuncinci ubude bazo zonke iintonga zesekethe ziya kufuneka. Ukuxhathisa ubuganga kugqitywe ngohlobo lomhlaba kunye nokufuma kwalo, ubushushu, kunye nendawo yenqanaba lamanzi aphantsi komhlaba. Ukusetyenziswa kokujikeleza unyaka, kuyanqweneleka ukuba inkanuko ibekwe ngokuyinxenye ngaphantsi kwenqanaba lokukhululwa komhlaba (xa amanzi ekhulula, ukuchasana komhlaba obolekisiweyo kunyusa kabukhali).

Inqanaba eliphezulu lamanzi aphantsi komhlaba 1.5-2.0 m), isekethe yokuphanziswa komhlaba senziwe ngemitya emithathu okanye emine yobude obuhambelanayo, iqhube nkqo emhlabeni (i-onilateral) ngecala le-1-3 m . Phakathi kwezikhonkwane ezixhume nge-welding kunye ne-string yensimbi okanye kwikona ebekwe kubunzulu obuyi-50-70 cm ngaphantsi kwenqanaba lomhlaba. Ukudibanisa ukuqhuba (umzekelo, i-wire yentsimbi yentsimbi yecandelo le-75 mm² okanye ucingo lobhedu oluyi-16 mm²) lidibene ngokuthembekileyo kwi-contour. Zonke iindawo ze-welding zinyanzelekile ukuba zibodwa (umzekelo, zigqunywe ngumswakama-bitumen mastic thestic). Itayara eqingqiweyo idla ngokufakwa eCamshaft, inokubekwa enyuka ngokwayo kunye nokufakelwa.
| Primu | Ukuchasana komhlaba, ohm • m |
|---|---|
| Udongwe olubi | 8-30 |
| Udongwe olomileyo | 30-70 |
| I-Cuswellock emanzi | I-40-100 |
| Sublock eyomileyo | I-100-250 |
| Isanti emanzi | I-150-400 |
| Isanti eyomileyo | Ukuya kuthi ga kwi-1000 okanye ngaphezulu |
Bala ubude obufunayo kwazo zonke izinto ze-contour yeyona ndlela ilula yokusebenzisa iikhalitha ezikwi-intanethi kwiindawo zokwakha. Qaphela, nangona kunjalo, ukuba ifomula inzima, kufuneka ukwazi ubungqingqwa, ubushushu kunye nezinye iimpawu ezihamba ngokulandelelana kwezinto ezininzi kunye nezinye iiparamitha, ngenxa yoko kube sengqiqweni yokunxibelelana ngokuchanekileyo.
