Abalimi bonke bayakwazi ukubaluleka kwamanzi ekukhuliseni iinkukhu.Umthamo wamanzi wamantshontsho umalunga ne-70%, kwaye umthamo wamanzi wamantshontsho phakathi kweentsuku ezisi-7 ubudala uphezulu ukuya kuma-85%, ngoko ke amantshontsho aphelelwa lula ngamanzi.Amantshontsho anezinga eliphezulu lokufa emva kokuphelelwa ngamanzi emzimbeni kwaye amantshontsho abuthathaka nasemva kokuba achache.
Amanzi nawo anefuthe elikhulu kwiinkukhu ezindala.Iinkukhu ziswele amanzi zinempembelelo enkulu kwimveliso yamaqanda.Ukuqalisa kwakhona amanzi okusela emva kokuba iinkukhu ziswele amanzi kangange yure ezingama-36 kuya kubangela ukuhla okungenakujikwa kwimveliso yamaqanda.Kwimozulu yobushushu obuphezulu, iinkukhu ziswele amanzi.Ukufa okukhulu kwisithuba seeyure.
Okwangoku, kukho iindidi ezintlanu zemithombo yokusela edla ngokusetyenziswa kwiifama zenkukhu: imithombo yokusela, imithombo yokusela ivacuum, imithombo yokusela iPlasson, imithombo yokusela iikomityi, nemithombo yokusela iingono.
Isiselo esinxilisayo
Umthombo wokusela ungabona ngcono isithunzi sezixhobo zokusela zesintu.Umthombo wokusela uphuhlile ukusuka kwimfuno yonikezelo lwamanzi ngesandla ukuya kunikezelo lwamanzi oluzenzekelayo lwangoku.
Iingenelo zomntu osela emkhombeni: kulula ukuyifaka isiselo esinxilisayo, akukho lula ukonakalisa, kulula ukuhamba, ngaphandle kweemfuno zoxinzelelo lwamanzi, kwaye sinokuqhagamshelwa kumbhobho wamanzi okanye itanki yamanzi ukuhlangabezana namanzi okusela amaqela amakhulu. iinkukhu ngaxeshanye (isinye isiselo esilingana ne-10 Plasones yamanzi aphuma kumthombo wokusela).
Ukungalungi kwabasela umkhombe: itanki yamanzi ibonakaliswe emoyeni, kunye nokutya, uthuli kunye nezinye i-sundries kulula ukuwela kwi-tank, kubangela ukungcola kwamanzi okusela;Iinkukhu ezigulayo zinokusasaza iintsholongwane lula kwiinkukhu ezisempilweni ngokusela amanzi;iitanki zamanzi eziveziweyo ziya kubangela ukuba indlu yeenkukhu ibe manzi;Amanzi amdaka;kufuneka ukucoca ngesandla yonke imihla.
Iimfuneko zofakelo kwabasela amanzi emkhombeni: Iziselo ezinxilisayo zifakelwa ngaphandle kocingo okanye eludongeni ukuthintela ukuba iinkukhu zinganyatheli kwaye zingcolise umthombo wamanzi.
Ubude bomntu osela utywala buziimitha ezi-2, kwaye inokudityaniswa kwimibhobho yamanzi eyi-6PVC, imibhobho eyi-15mm, imibhobho eyi-10mm kunye nezinye iimodeli.Abasela umkhombe banokudityaniswa kuthotho ukuhlangabezana neemfuno zamanzi okusela kwiifama ezinkulu.
Isiselo esifunxayo
Umthombo wokusela wevacuum, owaziwa ngokuba ngumthombo wokusela omile okwentsimbi, ngowona mthombo uqhelekileyo wokusela inkukhu.Nangona ineziphene zendalo, inemarike enkulu yabasebenzisi kwaye inyamezele ixesha elide.
Izinto ezilungileyo zemithombo yokusela i-vacuum: ixabiso eliphantsi, umthombo wokusela we-vacuum uphantsi malunga ne-2 yuan, kwaye uphezulu malunga ne-20 yuan kuphela.Ukunganxibi kunye nokuqina, kudla ngokubonwa ukuba kukho iketile yokusela phambi kwezindlu zasemaphandleni.Emva komoya kunye nemvula, inokusetyenziswa njengesiqhelo malunga nokusilela.
Ukungalungi kwemithombo yokusela i-vacuum: Kufuneka ihlanjululwe ngesandla 1-2 ngamaxesha ngosuku, kwaye amanzi afakwe ngesandla ngamaxesha amaninzi, achitha ixesha kwaye anzima;amanzi angcoliseka lula, ngakumbi kumantshontsho (amantshontsho mancinci kwaye kulula ukungena).
Ukufakwa komthombo wokusela i-vacuum kulula kwaye iquka kuphela umzimba wetanki kunye netreyi yamanzi.Xa usebenzisa, gcwalisa itanki ngamanzi, jija kwitreyi yamanzi, emva koko uyibophe ijongise phantsi emhlabeni, elula nelula ukuyisebenzisa, kwaye inokubekwa nanini na, naphi na.
Phawula:Ukuze unciphise ukutshiza kwamanzi okusela, kuyacetyiswa ukuba ulungelelanise ukuphakama kwepadi ngokobukhulu benkukhu, okanye ukuyiphakamisa.Ngokuqhelekileyo, ubude betreyi yamanzi kufuneka bube kumgangatho ofanayo nomqolo wenkukhu.
Umnxili wengono
Umntu osela ingono ngumntu osela kakhulu kwiifama zenkukhu.Ixhaphake kakhulu kwiifama ezinkulu kwaye ngoku sesona siselo saziwayo esizenzekelayo.
Iingenelo zomntu oselayo ingono: itywinwe, ihlukaniswe kwihlabathi langaphandle, akulula ukuba ingcoliswe, kwaye inokucocwa ngokufanelekileyo;akukho lula ukuvuza;unikezelo lwamanzi oluthembekileyo;ukonga amanzi;ukongezwa kwamanzi okuzenzekelayo.
Ukungalungi kwabasela ingono: Ukujongwa ukubangela ukuvaleka kwaye kunzima ukukususa;ukufakela nzima;ixabiso eliphezulu;umgangatho ongalinganiyo;kunzima ukucoca.
Umntu oseza ingono kufuneka asetyenziswe kunye nemibhobho engaphezu kwe-4 kunye nemibhobho emi-6.Uxinzelelo lwamanzi lwamantshontsho lulawulwa ku-14.7-2405KPa, kwaye uxinzelelo lwamanzi lwenkukhu ezindala lulawulwa ku-24.5-34.314.7-2405KPa.
Phawula:manzisa ngokukhawuleza emva kokufaka ititi, njengoko inkukhu iya kuyichola kwaye ayisayi kuphinda iyikrole xa kungekho manzi.Kuyacetyiswa ukuba ungasebenzisi izitywina zerabha ezilula ukuguga kunye nokuvuza, kwaye izitywina ze-PTFE zingakhethwa.
