Kunlik soat bo’yicha shaharning suv iste’molini grafigi
Texnologik qism
1.1.Nasoslarni ishlash tartibi.
Maksimal suv iste’moli mobaynida nasoslarni o’rtacha soatlik suv uzatuvi quyidagicha aniqlanadi;
QNS1=∑QS1/τ1=2332.8 /16=145.8 m3/soat
bu yerda, ∑QS1—maksimal suv iste’moli mobaynidagi umumiy suv sarfi;
τ1—maksimal suv iste’moli mobaynidagi davomiylik, τ1=16;
QS1—shu vaqt mobaynidagi soatlik suv sarfi;
Minimal suv iste’moli mobaynida nasoslarni o’rtacha soatlik suv uzatuvi quyidagicha aniqlanadi;
QNS2=∑QS2/τ2=295,3/8=36.9 m3/soat
bu yerda, ∑QS1— minimal suv iste’moli mobaynidagi umumiy suv sarfi;
τ2—minimal suv iste’moli mobaynidagi davomiylik, τ2=8;
QS2— shu vaqt mobaynidagi soatlik suv sarfi;
Maksimal topilgan va minimal topilgan nasosning suv uzatish miqdorining nisbati ishchi nasoslarni beradi;
N= QN1/ QN2=145.8/36.9=3.9≈4
Qabul qilingan ishchi nasoslarni miqdoriga ko’ra taxminiy bitta nasosni soatlik uzatish suv sarfi aniqlanadi;
QN=QN1/n=145.8/4=36.45 m3/soat.
Minimal suv iste’moli vaqtida ishlaydigan ishchi nasoslar soni quyidagicha aniqlanadi;
np2=QN2/QN=36.9/36.45=1,01≈1;
NN-ch=np.1=4
Nasoslar miqdori –kuniga nasos stansiyasini ishlash soati
NN-ch=np.1* T1+ np2* T2 =4*16+1*8=72soat.
Bitta aniqlangan hisobiy uzatish suv sarfi;
QNR=Qsut/NN-ch=9811,4 /72=136.3 m3/soat;
Hisob natijalari bo’yicha nasos stansiyasini kuniga ixtiyoriy soatda uzatiladigan suv sarfini aniqlaymiz;
Qn-ch=Qnr*nrch=136.3*4=545.2 m3/soat
Qn-ch=Qnr*nrch=136.3*1=136.3 m3/soat;
bu yerda, Qnr -bitta nasosni hisobiy suv sarfi;
nrch- ayni vaqtdagi ishchi nasoslarni miqdori
1.2.Bosimli minorani sarfini hisoblash
Suv iste’moli tartibi va 2-ko’taruv nasos stansiyasining ishi birgalikdagi tahliliga ko’ra bosimli minorani ishlash tartibini tashkil qiladi, ya’ni bosimli minoraga suv kelish kattaligini aniqlashga yordam beradi. Bunda bakdagi suvni hajmi belgilanadi, eng katta ahamiyatga ega bo’lgan minimal boshqarish bakini hajmi talab qilinadi. Bosimli minorani umumiy hajmini hisoblash uchun nazorat hajmini bitta tashqi va bitta ichki yong’inni o’chirishga ketadigan 10 minutlik zahiradagi suv sarfini hajmini hisoblash kerak.
WBM=Wbb+Wyo
bu yerda, Wbb - bosimli minoradagi boshqaruv hajmi sifatida bakda qolgan maksimal suv sarfi olinadi.
Wyo - 10 minutlik yong’in o’chirish uchun ketadigan suv zaxirasi u quyidagi formula orqali aniqlanadi;
Wyo=0,6(qt.yo.+qi.yo.)=0,6*(25+5)=18 m3
bu yerda, qt - bitta tashqi yong’inni o’chirish uchun suv sarfi;
qi - bitta ichki yong’inni o’chirish uchun suv sarfi;
Wbb=1825,25 m3, WBM=648+18=666 m3.
