O't o'chirishda suv ta'minoti me'yori
Ushbu hisobda aholi punktida sodir bo’lishi mumkin bo’lgan yong’inni o’chirish usuli va yong’inni o’chirishda ketadigan suv miqdori aniqlanadi. QM va Q 2.04.02-97 da yong’inni vodoprovod tarmog’ida o’rnatilgan maxsus gidrantlar yordamida o’chirish tavsiya etiladi.
Hisobda past bosimli o’t o’chirish vodoprovod tizimi qabul qilinadi. O’t o’chirish uchun suv manbasining o’zidan yoki bu usul texnik-iqtisodiy jihatdan maqsadga muvofiq bo’lmasa toza suv rezervuaridan olinadi.
Bu yerda: Qo’t.o’ch- o’t o’chirish uchun zarur bo’lgan suv me’yori
Bu yerda: Qichki-ichkaridan o’t o’chirish me’yori, binolarning sig’imiga bog’liq holda SNIP II-30-76 dan olinadi.
Qtash-tashqaridan o’t o’chirish me’yori bo’lib, QM va Q2.04.02-97 dan aholi soni va binolarning qavatiga qarab, hamda tashqaridan yong’in o’chirish 6-jadvalning ilovasiga asoslanib 10 l/sek olamiz.
n-bir vaqtning o’zida sodir bo’lishi mumkin bo’lgan yong’inlar soni.n=1
T-yong’in o’chirish uchun ketadigan vaqt. T=3 soat.
Suv ta'minoti variantlari
Suv yеr osti manbasidan olinadi. Yеr osti suvi dinamik sathining chuqurligi yеr sathiga nisbatan 10 mеtrdan ko’p bo’lganda quyidagi sxemani qabul qilamiz.
1 – quvurli quduq 5 – bosimli suv minorasi
2 – I – ko’tarish nasos stansiyasi 6 – suv tashish quvurlari
3 – toza suv rеzеrvuarlari 7 – vodoprovod tarmog’i
4 – baktеrisid moslamasi bilan jihozlangan II ko’tarish nasos stansiyasi
Statik sathni quyidagicha aniqlaymiz:
Dinamik sathni quyidagicha hisoblaymiz
S – suv sathining tushishi
Qsut –sutkalik suv sarfi, m3/sut.
ТnsI –birinchi ko’tarish nasos stansiyasining ish vaqti,Тns1 = 24 soat.
qsol - quduqning solishtirma suv sarfi, l/s.
Quvurli quduq hisobi
Quvurli quduq filtrini hisoblash.
Filtrni turi suvli qatlam jinsiga bog’liq holda QMQ 2.04.02-97 dan maxsus jadvaldan tanlanadi. Filtr suvli qatlamga o'rnatiladi. Filtrning umumiy uzunligi suvli qatlamdan katta bo'lmasligi kerak. Aks holda filtrning FIK kamayib boradi.
Filtrni talab maydoni:
Vkir–filtrga kirish tezligi
Kf= uchun.
Filtr uzunligi:
=0,2-0.25 –g’ovaklik
d- filtrning diametri
Tanlashimiz mumkin bo’lgan diametrlar:
d=100mm, 150mm, 200mm, 250mm, 300mm, 350mm, 400mm.
Metrda olgan holda: d=0.1m, 0.15m, 0.2m, 0.25m, 0.3m, 0.35m, 0.4m
markasini tanlash
Nasos markasini tanlash uchun 2 ta asosiy ko’rsatkichni bilishimiz zarur:
Suv sarfi – Q, m3/soat;
Ko’tarish balandligi – H, m;
Nasosning suv sarfi quyidagicha aniqlanadi:
73.54
To’la bosimni quyidagicha aniqlaymiz:
m
Nasos markasi:ESV-10-63-65
Q=63 m3/soat;
H=65 m;
FIK=62 %
