Dej dej yog ib qho teeb meem tshaj plaws hauv tsev ib lub teb chaws . Tshaj los ntawm tag nrho cov nyob ib ncig ntawm koj tuaj yeem ua ib qhov dej nruab nrab, vim li ntawd ntau tus tswv tsev ntawm ntiav tsev xav tau ib tus neeg haus dej.
Kev tsim kho ntawm ib lub qhov dej tau zoo yog ib txoj kev xaiv zoo tshaj plaws rau lub cev. Thiab yuav kom txhim kho cov dej hauv tsev, koj yuav tsum paub tias cov khoom siv yuav tsum ua li cas rau qhov no. Tsab xov xwm no yuav qhia koj txog qhov zoo li cas ntawm ib qho chaw pov thaiv zoo rau ib qho dej.
Ntaus nruab ntawm cov yas cais
Lub cais yog ib lub thawv yas ntawm cylindrical puab. Yav dhau los, lawv tau siv tshwj xeeb rau cov dej hauv qab, niaj hnub no cov yas cais nyob rau hauv qhov dej yog ib qho tseem ceeb ntawm kev siv dej rau hauv tsev. Raug cais tawm, feem ntau yog ua los ntawm polypropylene los yog polyethylene. Lawv tau nruab nrog ib lub hnab hau nrog ib lub caj dab ntawm ntau diameters. Lub hau yog tom qab insulated. Ob lub kaus poom no feem ntau nyob rau hauv qab thiab phab ntsa ntawm cais - nkag mus rau lub khauj khaum thiab xa cov yeeb nkab ciaj ntsaws.
Lub caisson ua rau tsim nyob rau hauv dej ntawm ib hom chamber, dawb ntawm cov dej. Cov cuab yeej tsis muaj dej tsis yog siv los tiv thaiv kom txhob muaj kev nrheev zoo los ntawm kev khov thiab ntawm kev puas tsuaj ntawm cov kav dej. Qhov tshwj xeeb tshaj yog cov kev teeb tsa ntawm ib tug cais nyob rau hauv ib seem nrog ib theem siab ntawm av. Tsis tas li, lub xub ntiag ntawm lub nraub qaum no ua kom yooj yim txij nkawm ntawm qhov dej. Hauv ib lub koob yees duab, cov cuab yeej tsim nyog rau lub koom haum ntawm cov dej muaj nruab: lub tank cia, lub qhov dej khoom siv hluav taws xob, thiab lwm yam.
Cov yas caiscins muaj qhov tshwj xeeb zoo:
- lawv tsis raug rau corrosion, tsis xeb thiab tsis rot;
- tsis tas yuav tsum muaj daim ntawv thov ntawm cov ntaub ntawv pov thawj;
- Lawv muaj qhov hnyav hnyav piv rau cov hlau cais, thiab yog li ntawd yooj yim rau nruab;
- muab kev ruaj ntseg hydro thiab cua sov thaiv;
- Tsis ntev - ib lub thawv yas yuav kav koj yam tsawg kawg li ob peb xyoo;
- tiv taus kev txhoj puab heev;
- tsis muaj voj voog ntim vim cov tshuab ntawm kev sib hloov molding;
- muaj ib txoj kev siab tawv (cov phab ntsa tuab hauv 10-40 hli);
- muaj lub thermal conductivity thiab, raws li ib qho tau txais, yuav tsis muaj insulate cov phab ntsa hauv cov caisson.
Txawm li cas los xij, muaj cov yas cais thiab lawv cov teebmeem, qhov tseem ceeb ntawm cov khoom siv uas yog qhov yuav tsum tau siv lub thawv rau pob zeb. Qhov no tsis siv rau tag nrho cov khoom, thiab tsuas yog xav tau nyob rau hauv lub sijhawm uas muaj ib qho nyuaj hauv av los yog tob ntawm nws khov nws dhau lawm.
Cov cais yuav muab tso rau hauv ib qhov tob - tsis pub dhau 1.2-2 m. Nws tuaj yeem sib txawv nyob ntawm qhov zoo ntawm cov av thiab qhov tob ntawm nws khov. Lub installation ntawm ib tug yas caisson, tsim rau ib tug zoo on dej, yog nqa tawm nyob rau hauv no txoj kev:
- Ua ntej, npaj ib aub tsiv thiab "cushion" ua los ntawm cov xuab zeb nrog ib lub thickness ntawm tsawg kawg 20 cm.
- Muab lub nruag ncaj qha saum lub taub hau zoo.
- Muaj qhov sib txawv uas nyob nruab nrab ntawm cov phab ntsa ntawm lub khawb av thiab lub pob zeb, ua kom dej sib tov ntawm cov xuab zeb thiab cement nyob rau hauv ib feem ntawm 5: 1.
- Yog tias muaj dej hauv av hauv cheeb tsam koj nyob, qis tshooj hauv qab yuav tsum muab tso rau hauv ib lub pob zeb ua ke.
- Tom ntej no, muab khij lub kaspaum thiab txuas nrog cais tawm mus rau qhov dej.
- Yas caisson yuav tsum tau sau nrog av, kom zoo zoo nws txhua txhua 20 cm.
Cov producers ntawm cov yas caissons xws li Triton-K, Aquatek, Hermes Group, Nanoplast thiab lwm tus neeg muaj coob xav hnub no.
