Iitrakthi zokulahla kwamanzi angcolileyo ziyinxalenye ephambili ekufakekeni kweziqhwithi zomoya . Ngoko ke, ukukhethwa kwezi fowuni kufuneka kuphathwe ngokucophelele, ngakumbi xa udibanisa ngokuzimeleyo inkqubo yokuthuthwa kwamanzi kweso siza. Makhe sibone uhlobo lweetayiti zamanzi.
Iimpawu zokukhethwa kunye nokufakwa kweetayiti zokukhupha amanzi
Xa ukhetha ii-trays ukuba ufake, kufuneka ugxininise kumaphuzu ambalwa.
Okokuqala, le yiklasi yabo, enika umgangatho womthwalo ovumelekileyo. Zizonke zikho ezintandathu zeeklasi:
- A-15 - zenzelwe umthwalo ophezulu weetoni eziyi-1.5. Ezi treyiti zifakwe kwiindawo ezincinane, izizathu zemidlalo, kwindawo yokupaka, njl.;
- Iitrakethi zeklasi B-125 - ukuya kutsho kwi-12.5 itoni - zihlala zisetyenziselwa ezindlini zamakhaya, nakwiipaki zeemoto, ama-cooperatives egalaji, njl.;
- C-250 - xhathisa umthwalo weetoni ezingama-25 kwaye isetyenziselwa ukwakhiwa kwendlela;
- I-D-400 - isetyenziselwa kwiindawo zoshishino kunye neendlela eziphambili zendlela, njengoko zenzelwe ukulayishwa ukuya kwiiyure ezingama-40;
- Iithagethi ze-E-600 ubunzima beetoni ezingama-60 kwaye zisetyenziselwa kumashishini amakhulu, iindawo zokugcina impahla kunye neendawo zokugcina impahla;
- F-900 - iimodeli ezinamandla kunabo bonke, zinokumelana nemithwalo yeetoni ezingama-90. Inkalo yesicelo sabo ngamashishini apho kusetyenziswa izixhobo ezinzima, ezifana neenqwelo, iitanks, njl.
Ukusuka ngasentla, sigqiba ukuba abantu abaqhelekileyo kubathengi abaqhelekileyo beeklasi ze-B-125 kunye ne-C-250, kuba ezi zithuthi zifakwe kwiindawo zezindlu zelizwe.
Okwesibini, kubalulekile ukuqwalasela umthamo weetayiti zokuthuthwa kwamanzi, okubhekiselele ngqo kubukhulu bawo. Kubaluleke kakhulu ukubala i-cross-sectional area, kwaye ngenxa yoko kuyimfuneko ukulinganisa ububanzi becandelo le-hydraulic ye-tray kunye nokuphakama kwalo. Ngenxa yezi zibalo, umthamo wee-trays kufuneka uqhathanise umthamo wesondlo sakho sesiphepho.
Kwaye okwesithathu, xa ukhetha, qwa lasela ingqalelo kwimiba yokuveliswa kweetayiti .
Iqineleyo yikhonkrithi, eyenziwa ngokusebenzisa iteknoloji yokunyanzeliswa. Ezi iiteyiti ziyi-monolithic kwaye zingenawo amanzi. Ukongezelela, abaxhatshazwa kumaqondo atshisayo aphantsi kunye neempembelelo ezahlukeneyo zamachiza - oku kuthetha ukuba zilungelelanise nayiphi na inkqubo yokuthuthwa kwamanzi. Ukuba ufuna iimodeli ezingaphezulu kwamandla aphezulu, unokuqwalasela ukhetho lokuthenga izitishi zeesitreji eziqinisiweyo eziqiniswe ngetsimbi zecala. Ezi iiteyiti zihlala zixhotywe ngeempahla ezenziwe ngetsimbi ephosiweyo okanye insimbi engenasinxibe kunye neenyosi okanye iinkuni ezidibeneyo.
Ukususela kwiimpazamo zezakhiwo zekhonkco sibona ubunzima babo.
Ngenxa yokuthuthwa kwamanzi kwamanzi aphantsi, ikhetho elithandekayo ngakumbi kukukhethwa kwamatye eplastiki. Ekubeni ubunzima bezithuthi apha buphantsi, iipayipi zeplastiki okanye, njengokuba zibizwa ngokuba, ama-gutters yindlela efanelekileyo. Badibanisa amandla aphezulu ngokwaneleyo ngenxa yezinkuni eziqulunqwe ngokucacileyo, kunye nobukhulu obuncinane ngokuthelekiswa nezakhiwo zekhonkrithi. Ezi ndlela zilula ukufaka, ukuxhatshazwa kwimeko yemichiza,
Ukukhetha iiteyiti zokugubha, ungathenga umzekelo kunye nomgca wendlela yokuhamba. Imizekelo yePlastiki idla ngohlobo olufanayo lweplastiki okanye i-metal sieves. Kuyathakazelisa, ukuyila komjelo ngamnye kuklanywe ngendlela enokukuvumela ukuba uyivumelise ngokulula kwimibhobho eguqula amanzi kumqokeleli, nakwiitrakthi eziphambili.
Umgangatho osemgangathweni wee-trays ezihlambayo ziyahluka ukusuka kwi-2 ukuya kwi-5%, kodwa ngelo xesha unako ukunyusa okanye ukwehlisa ngokuxhomekeke kwiimfuno zomhlaba ngamnye.
