Txoj cai nqes hav ntawm phwj yeeb nkab - ib tug guarantee ntawm nws tus kheej-tu

Rau lub npe ntawm dej tej zaum siv lo lus "cloaca" nyob rau hauv thaum uas tig mus muaj lwm lub ntsiab lus: incredibly qias neeg qhov chaw. Nws yog tsis kaj siab, ntawm chav kawm, tab sis hais tias yog cov kev muaj tiag. Physiological thiab tsev neeg tib neeg tseem ceeb heev functions yog nrog los ntawm ib tug tsis tshua loj npaum li cas ntawm pov tseg. Thiab tsis yog txhua txhua ntawm lawv sewerage system, los ntawm kev uas lawv pov tseg ntawm, muaj peev xwm "zom" tsis muaj txim.

Piv txwv li, tej seem ntawm fatty khoom noj uas yuav nyob twj ywm rau lub puab phab ntsa ntawm cov lim dej kav, tshwj xeeb tshaj yog yog hais tias tus hlau kav, roughened hauv. Los ntawm no nplaum quav hniav lo ib tug tshiab daim fatty pov tseg, thiab hais txog. Yog li overgrow hauv cov lim dej yeeb nkab.

Txhais tau hais tias rau tshwj kom txhob clogging - tus nqes hav ntawm cov av yeeb nkab, muab ib tug self-tu nyhuv ntawm lub cev. Cov nyhuv no yog raws li nyob rau hauv ob lub cev phenomena: lub ntiajteb txawj nqus thiab hydraulics. Lub ntiaj teb gravitational teb attracts rau nws chaw tag nrho cov nyob rau hauv lub ntiaj kawm, xws li dej khib nyiab. Yog hais tias ua ntej kev txiav txim degree ntawm sau yog kav dej phwj system los xyuas kom meej tias lawv tsiv mus nyob hauv cov kav dej ntawm ib yam ceev, cov dej lawv tus kheej yuav dab tsub zuj zuj ntawm pov tseg hauv cov hlab.

Cov nqi ndlwg ntawm wastewater nyob rau hauv lub cev thiab cov filling theem ntawm cov system yog inversely xwm yeem mus rau txhua lwm yam. Yog hais tias qhov kev nce toj ntawm cov lim dej yeeb nkab, ib txhij nrog ib tug txo nyob rau hauv lub txhaws system yuav ua rau kom lub tus nqi ndlwg ntawm cov dej thiab vice versa.

Qhov loj thiab ntau qhov loj ntawm lub tsev, ntau dua qhov lub xov tooj uas yog therein kav dej fixtures tau txais kev pab los ntawm ib tug uas nws kim heev phwj system. Nyob rau hauv tej yam, thaum nws yog tsim nyog los xyuas kom meej zoo lub yeeb nkab kev tsis ncaj ncees txhais tau tias ntawm ib tug ntsug yeeb nkab-tso txoj kev (i.e., ntawm ib txoj cai kaum sab xis rau hauv pem teb theem). Muaj coob tus neeg xav siv ib tug cam khwb cia-hlau kav rau kua: los ntawm kev lig kev cai, vim hais tias ntawm lub dag lub zog thiab impressive thiav (80 xyoo warranty). Txawm li cas los, vim rau lawv cov qib high nqi thiab siab hlau cov ntsiab lus, raws li tau zoo raws li tseem ceeb luj, complicating lub installation, yog nce opting rau cov kav dej ua los ntawm cov yas.

Cov zoo yog suav tias yog ib tug nqes hav ntawm cov av yeeb nkab uas txuas lub huv kws thiab cov lim dej puab riser system angled downward. Tab sis qis raj rau hauv qab no rau theem, qhov twg lub internal system yog kev cob cog rua kom cov dej network yog tsis yooj yim sua.

Thaum lub zoo kev tsis ncaj ncees nqi kuj influences lub lub cheeb ntawm lub phwj yeeb nkab: 2 degrees - rau 85-100 hli 3 degrees - 40-50 hli.

Nyob rau hauv txhua rooj plaub, nws yuav tsum tau ua mus rau lub zoo tshaj tawm los ntawm lub wastewater nyob rau hauv lub system (0.7-1 m / s). Qhov no yog ib qho tseem ceeb vim tshaj no tus nqi ua rau ib tug txo nyob rau hauv nws tus kheej-tu nyhuv vim ntws sib cais thiab braking khib nyiab. Nyob rau hauv tas li ntawd, lub zog suab nrov theem thaum tus ndlwg lug kub, uas yog tshwj xeeb tshaj yog tseem ceeb heev rau yas kav tsis muaj kev tiv thaiv suab nrov rwb thaiv tsev.

Nws yog ib tug tas nrho kev ua yuam kev twb kev txuas thaum mounting cov lim dej kav ua los ntawm ntaub ntawv sib txawv. Qhov no txhais tau tias nyob rau hauv tus ntawm tshav kub lawv yuav nthuav txawv. Raws li ib tug tshwm sim, tsis yog lub tawg kev tsis ncaj ncees phwj yeeb nkab - tag nrho cov system yuav muaj neeg xiam.

Muab xam los ntawm cov dej ceev nyob rau hauv cov lim dej system yog txo mus rau kev nrhiav ib tug nqi koj tshuav ntawm cov kav dej thiab lawv Amortization overgrowth. Qhov no tus nqi yog hu ua nyob rau hauv hydraulics economic ceev.
