Izesekeli zethangi lamanzi
(1) Ipayipi lokungena kwamanzi: Ipayipi lokungena kwamanzi lethangi lamanzi ngokuvamile lifinyelelwa kusuka odongeni oluseceleni, futhi lingafinyelelwa kusuka phansi noma phezulu. Uma ithangi lamanzi lisebenzisa ingcindezi yenethiwekhi yamapayipi ukuze lingene emanzini, indawo yokungena yamapayipi kufanele ifakwe ivalvu yebhola elintantayo noma ivalvu ye-hydraulic. Ivalvu yebhola elintantayo ngokuvamile ingaphansi kuka-2. Ububanzi bevalvu yebhola elintantayo bufana nobepayipi lokungena. Ivalvu ngayinye yebhola elintantayo kufanele ifakwe ivalvu yokuhlola ngaphambi kwayo.
(2) Ipayipi lokukhipha: Ipayipi lokukhipha amanzi ethangini lamanzi lingaxhunywa odongeni oluseceleni noma phansi. Iphansi lepayipi lokukhipha amanzi elixhunywe odongeni oluseceleni noma ngaphezulu kwepayipi lokukhipha amanzi elixhunywe phansi kufanele libe phezulu ngama-50 mm kunephansi lethangi. Indawo yokukhipha amanzi ephayiphini lamanzi kufanele ihlinzekwe nge-valve yesango. Amapayipi okungenisa amanzi nawokukhipha amanzi ethangini lamanzi kufanele abekwe ngokwehlukana. Uma amapayipi okungenisa amanzi nawokukhipha amanzi eyipayipi elifanayo, kufanele kufakwe ama-valve okuhlola emaphayiphini okukhipha amanzi. Uma kudingeka kufakwe i-valve yokuhlola, kufanele kusetshenziswe i-valve yokuhlola ejikayo enokumelana okuncane esikhundleni se-valve yokuhlola ukuphakama, futhi ukuphakama kufanele kube ngaphezu kwe-1m ngaphansi kwezinga lamanzi eliphansi kakhulu lethangi lamanzi. Lapho abantu abaphilayo nabacimi bomlilo behlanganyela ithangi lamanzi, i-valve yokuhlola ephayiphini lokukhipha amanzi kufanele okungenani ibe ngaphansi ngama-2m kunephayiphi le-siphon yamanzi aphilayo (uma iphansi kunephayiphi, i-vacuum ye-siphon ephilayo iyabhujiswa, futhi ukuphuma kwamanzi kuphela ephayiphini lokukhipha amanzi omlilo kuyaqinisekiswa), ukuze ibe nokucindezela okuthile kokucindezela i-valve yokuhlola. Uma kwenzeka umlilo, amanzi agciniwe omlilo angaba nomthelela omkhulu.
(3) Ipayipi lokugcwala: ipayipi lokugcwala lethangi lamanzi lingaxhunywa kusukela odongeni oluseceleni noma phansi, futhi ububanzi balo bepayipi bunqunywa ngokwezinga lokugeleza eliphezulu lethangi lokukhipha amanzi, futhi kufanele libe likhulu kunepayipi lokungena kwamanzi. Akukho valve okufanele ifakwe epayipini lokugcwala. Ipayipi lokugcwala akufanele lixhunywe ngqo nohlelo lokukhipha amanzi, futhi kumele kusetshenziswe ukugeleza okungaqondile. Ipayipi lokugcwala kufanele libe nezinyathelo zokuvimbela uthuli, izinambuzane, omiyane nezimpukane ukuthi zingangeni, njengesivalo samanzi kanye nesihlungi.
(4) Ipayipi lokukhipha amanzi: Ipayipi lokukhipha amanzi ethangini lamanzi kufanele lixhunywe kusukela phansi endaweni ephansi kakhulu. Umfanekiso 2-2N Ipayipi lokukhipha amanzi Ithangi lamanzi lokulwa nomlilo kanye netafula lokuhlala lifakwe ivalvu yesango (ivalvu yokuvimbela akufanele ifakwe), engaxhunywa nepayipi lokugcwala kwamanzi, kodwa akumele ixhunywe ngqo nohlelo lokukhipha amanzi. Uma kungekho zidingo ezikhethekile, ububanzi bepayipi ngokuvamile buyi-DN50.
(5) Ipayipi lokungenisa umoya: ithangi lamanzi okuphuza kufanele linikezwe isembozo sebhokisi esivaliwe, kanti isembozo sebhokisi kufanele sinikezwe imbobo yokungena kanye nepayipi lokungenisa umoya. Ipayipi lokungenisa umoya linganwetshwa ngaphakathi noma ngaphandle, kodwa hhayi endaweni yamagesi ayingozi. Umlomo wepayipi kufanele ube nesivikelo sokuhlunga ukuvimbela uthuli, izinambuzane kanye nomiyane ukuthi bangangeni. Ngokuvamile, umlomo wepayipi kufanele ubekwe phansi. Amavalvu, izivalo zamanzi kanye namanye amadivayisi avimbela ukungena komoya akufanele afakwe ku-snorkel. Ipayipi lokungenisa umoya akumelwe lixhunywe ohlelweni lokukhipha amanzi kanye nomsele wokungenisa umoya. Ipayipi lokungenisa umoya ngokuvamile lingububanzi bepayipi le-DN50.
(6) Igeyiji yezinga: Ngokuvamile, igeyiji yezinga lengilazi kufanele ifakwe odongeni oluseceleni lwethangi lamanzi ukukhombisa izinga lamanzi khona lapho. Uma ubude begeyiji eyodwa yezinga bunganele, amageyiji amabili noma ngaphezulu angafakwa phezulu naphansi. Ukugqagqana kwamageyiji amabili aseduze kwezinga akufanele kube ngaphansi kuka-70 mm, njengoba kuboniswe kuMfanekiso 2-22. Uma ithangi lamanzi lingenaso isikhathi sesignali yezinga loketshezi, ithubhu yesignali ingasethwa ukuze inikeze isignali yokugcwala. Iphayiphi yesignali ngokuvamile ixhunywe odongeni oluseceleni lwethangi lamanzi, futhi ukuphakama kwayo kufanele kubekwe ukuze phansi kwephayiphi kuhambisane nephansi lephayiphi yokugcwala noma ubuso bamanzi okugcwala bokugqagqa. Ububanzi bephayiphi ngokuvamile buyithubhu yesignali ye-DNl5, engaxhunywa esitsheni sokuwasha kanye nesitsheni sokuwasha ekamelweni lapho kuvame ukuba nabantu abasebenza khona. Uma izinga loketshezi lethangi lamanzi lixhunywe nephampu yamanzi, idivayisi yokudlulisela izinga loketshezi noma yesignali ifakwe odongeni oluseceleni lwethangi lamanzi noma isembozo esiphezulu. Idivayisi yokudlulisa noma yesignali esetshenziswa kakhulu ihlanganisa uhlobo lokuntanta, uhlobo lwenduku, uhlobo lwe-capacitor kanye nohlobo lokuntanta. Izinga lamanzi kagesi eliphezulu neliphansi lethangi lamanzi lomfutho wephampu yamanzi kufanele licatshangelwe ukuze kugcinwe ivolumu ethile yokuphepha, izinga lamanzi okulawula kagesi eliphezulu lephampu yokumisa ngokushesha kufanele libe ngaphansi kwezinga lamanzi okugcwala elingu-100 mm, kanye nezinga lamanzi okulawula kagesi elincane lephampu evulekile ngokushesha kufanele libe phezulu kunezinga lamanzi elincane elingu-20 mm, ukuze kugwenywe ukugcwala noma ukugoba ngenxa yephutha.
(7) Isembozo sethangi lamanzi, ileli langaphakathi nelangaphandle.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
