Kusintha Kukhazikitsa Mizere ya Madzi a Pansi pa Dziko Ndi Ukadaulo Wodzipangira Welded Pipe wa Helical
Yambitsani:
Chitoliro cha Mzere wa Madzi Pansi pa PansiKukhazikitsa nthawi zonse kwakhala vuto lalikulu pa ntchito zomanga ndi zomangamanga. Mwachikhalidwe, kumakhala ndi ntchito zotenga nthawi komanso zogwira ntchito zambiri zomwe zimaika pachiwopsezo chitetezo cha ogwira ntchito komanso nthawi ya ntchito. Komabe, pamene ukadaulo wowotcherera mapaipi wodzipangira wokha ukupita patsogolo, kuyambitsidwa kwa mapaipi olumikizidwa mozungulira kukusinthiratu makampani.
Kuwotcherera mapaipi odzichitira okha: tsogolo la zomangamanga zogwira mtima:
M'zaka zaposachedwapa, kubuka kwakuwotcherera mapaipi odzichitira okhaUkadaulo wasintha makampani omanga. Ukadaulo wamakonowu umachotsa kufunikira kogwiritsa ntchito soldering ndi manja, motero umawonjezera magwiridwe antchito, umakweza ubwino ndi kuchepetsa ndalama. Mwa kuphatikiza kuwotcherera mapaipi odziyimira pawokha ndi chitoliro cholumikizidwa mozungulira chomwe chimapangidwa makamaka pamizere yamadzi apansi panthaka, maubwino angapo ofunikira angapezeke.

Mphamvu ya chubu chozungulira cholumikizidwa:
Chitoliro cholumikizidwa cha HelicalIli ndi msoko wozungulira wozungulira, womwe umapangitsa kuti ikhale yankho labwino kwambiri poyika mizere yamadzi pansi pa nthaka. Mapaipi awa amapangidwa ndi chitsulo chapamwamba kwambiri, chomwe chimatsimikizira kulimba komanso kukana dzimbiri, zinthu ziwiri zofunika kwambiri kuti ntchitoyo ikhale yayitali. Kapangidwe kawo kapadera kamapereka mphamvu yapamwamba komanso umphumphu wa kapangidwe kake, zomwe zimawalola kupirira kupsinjika kwakukulu mkati ndi kunja.
Kukhazikitsa mizere ya pansi pa nthaka mosavuta:
Kugwiritsa ntchito ukadaulo wowotcherera mapaipi wodziyimira pawokha limodzi ndi mapaipi olumikizidwa mozungulira kumafewetsa njira yonse yokhazikitsira mizere ya pansi pa nthaka. Kuyambira kufukula mpaka kulumikizana komaliza, njira yatsopanoyi imachepetsa kwambiri ndalama zogwirira ntchito, imafupikitsa nthawi ya polojekiti, komanso imawonjezera zokolola zonse.
Kupititsa patsogolo magwiridwe antchito ndi zokolola:
Makina olumikizira mapaipi odzipangira okha amachotsa zolakwika za anthu ndikuwonetsetsa kuti ma weld olondola komanso okhazikika kutalika konse kwa chitolirocho. Kulondola kumeneku pamodzi ndi mphamvu ya chitoliro cholumikizira mozungulira zimapangitsa kuti pakhale dongosolo logwira ntchito bwino kwambiri lomwe limatha kuyendetsa madzi popanda kutayika kwakukulu. Kugwira ntchito bwino kwa hydraulic kumeneku kumawonjezera ntchito yonse ya dongosolo la madzi apansi panthaka.
Kukhalitsa ndi moyo wautali:
Chitsulo chapamwamba chomwe chimagwiritsidwa ntchito popanga mapaipi olumikizidwa ndi spiral chimatsimikizira kulimba kosayerekezeka, zomwe zimapangitsa kuti zikhale zabwino kwambiri poyika pansi pa nthaka. Kukana kwake dzimbiri, kuphatikiza ndi ma spiral welds osalekeza, kumachotsa chiopsezo cha kutuluka kwa madzi ndikuwonjezera moyo wa mapaipi amadzi. Zotsatira zake, ndalama zokonzera zimachepetsedwa ndipo kufunikira kokonzanso pafupipafupi kumachepa kwambiri.
Kulimbikitsa chitetezo cha ogwira ntchito:
Kugwiritsa ntchito ukadaulo wowotcherera mapaipi wodziyimira pawokha kumaika patsogolo chitetezo cha ogwira ntchito mwa kuchepetsa kufunikira kowotcherera pamanja ndikuchepetsa zoopsa zomwe zingachitike chifukwa cha izi. Ukadaulo watsopanowu umaonetsetsa kuti ogwira ntchito sakumananso ndi utsi woopsa wowotcherera, malo ogwirira ntchito oopsa komanso ngozi zomwe zingachitike, zomwe zimapangitsa kuti malo azikhala otetezeka.
Pomaliza:
Kuphatikiza kwa ukadaulo wowotcherera mapaipi odziyimira pawokha ndi mapaipi olumikizidwa mozungulira kukusinthiratu kukhazikitsa mizere ya pansi pa nthaka. Njira yatsopanoyi ikukonzanso makampani omanga mwa kukonza magwiridwe antchito, kulimbitsa kulimba, kuwonjezera zokolola komanso kulimbikitsa chitetezo cha ogwira ntchito. Pamene tikupitiliza kugwiritsa ntchito ukadaulo wamakonowu, titha kuyembekezera njira zokhazikika komanso zodalirika zoyendetsera mizere ya pansi pa nthaka zomwe zidzakwaniritse zosowa zamtsogolo.
