Lub twj tso kua mis siab stabilizing yog ib hom hluav taws kub twj tso kua mis, uas yog siv los ua kom cov dej tua hluav taws thiab ua kom lub siab ruaj khov ntawm cov khoom siv hluav taws xob ntawm cov hluav taws xob hluav taws xob, kom ntseeg tau tias lub xeev siab ua ntej thiab tom qab dej siab ntawm qhov system. Thaum lub taub hau da dej los yog hluav taws tua hluav taws ntws tawm, nws tuaj yeem ntws tawm cov dej ntim thiab cov dej siab uas yuav tsum tau ua kom tau raws li cov dej tua hluav taws. Ob lub twj tso kua mis siab stabilizing thiab muaj peev xwm nce lub twj tso kua mis yog lub peev xwm nce chaw. Lub twj tso kua mis siab ruaj khov ua haujlwm thaum lub taub hau da dej thiab hluav taws kub tsis tau ntws tawm, thiab lub peev xwm ua kom lub twj tso kua mis ua haujlwm thaum lub taub hau da dej thiab hluav taws kub tau ntws tawm, thiab cov dej siab ntawm cov dej tua hluav taws yog qhov txaus, yog li nws yuav tsum tau nce ntxiv. dej siab.
China's current standard "standard for fire protection design of high rise civil buildings" (gbj50045-95) (hereinafter referred to as "high standard") has secondary regulations for capacity increasing facilities (including pressure stabilizing pump): "7.4.8.1 the water output of capacity increasing pump shall not be greater than 5L / s for fire hydrant water supply and 1L / s for main sprinkler fire extinguishing." There are preconditions for a certain regulation. One of the conditions is that the fire water supply is fragmentary and non pneumatic water tank; The second condition is that the small amount of leakage of indoor fire water supply is important in the sealing part of the water pump. The regulation of the article does not mean that the stabilized pressure pump is determined according to a certain flow under any condition, any condition and any time.
Lub peev xwm nce twj tso kua mis raug xa mus rau hauv cov kev cai siab hais txog ob qho tib si lub peev xwm nce twj tso kua mis thiab lub siab stabilizing twj tso kua mis rau siab stabilization. Cov kev cai txheem tsis muab faib. Raws li txoj cai, kev ua haujlwm thiab kev ua haujlwm ntawm lub peev xwm nce twj tso kua mis thiab lub siab ruaj khov twj tso kua mis sib txawv, thiab lawv cov txiaj ntsig ntws tsis yog qhov txawv.
Lub peev xwm nce lub twj tso kua mis yog siv los tso tawm lub taub hau da dej thiab hluav taws tua hluav taws, thiab cov dej siab ntawm cov dej tua hluav taws yog cov khoom seem. Nws yog ib qho tsim nyog yuav tsum tau ua kom muaj peev xwm ua kom muaj peev xwm ua tau raws li cov dej siab ntawm cov dej tua hluav taws. Nyob rau lub sijhawm ntawd, qhov ntws ntawm lub twj tso kua mis yuav tsum xyuas kom lub qhov hluav taws xob ntws ntawm lub taub hau da dej lossis lub qhov hluav taws kub, uas yog, tsis pub tsawg dua 1L / s lossis 5L / s. Txawm li cas los xij, thaum lub peev xwm nce lub twj tso kua mis pib, lub twj tso kua mis tseem ceeb kuj tau pib tom qab. Lub luag hauj lwm ntawm lub peev xwm nce twj tso kua mis tsis yog ceev heev thiab rov ua dua.
Lub twj tso kua mis siab ruaj khov yog qhov sib txawv ntawm lub peev xwm nce lub twj tso kua mis, uas yog siv los xyuas kom meej lub siab ua haujlwm ua ntej thiab tom qab tus kheej txau qhov system thiab qhov hluav taws kub hydrant system. Thaum nws ntws tawm, nws tuaj yeem ua tau raws li cov dej siab thiab cov dej ntim qhov xav tau ntawm cov dej tua hluav taws. Nws qhov ua haujlwm yuam kev yog feem ntau pom tseeb, yog li lub peev xwm nce dej twj tso kua mis xa mus rau hauv tus qauv tseem ceeb yog hais txog lub siab stabilizing twj tso kua mis, tshwj xeeb tshaj yog lub siab stabilizing twj tso kua mis ntawm active sprinkler system.
Tus nqi ntws ntawm lub siab stabilizing twj tso kua mis nyob ntawm ntau yam, ntawm cov khoom tseem ceeb tshaj yog:
(1) Qeb ntawm qhov chaw: thaum lub siab stabilizing twj tso kua mis siv qhov chaw ntawm cov tshuaj tsuag, xav txog cov dej hauv lub taub hau da dej; Thaum nws yog siv rau hluav taws kub hydrants, xav txog cov dej ntim ntawm cov hluav taws kub hydrant.
(2) Seb puas muaj pneumatic dej tank qhov teeb tsa. Thaum tsis muaj pneumatic dej tank qhov system teeb tsa, qhov ntws ntawm lub twj tso kua mis siab ruaj khov yuav tsum tsis txhob siab tshaj qhov ntim dej ntawm lub taub hau da dej lossis hluav taws kub. Thaum lub pneumatic dej tank yog nruab, lub piecemeal dej ntxiv thiab siab guarantee yog siv los ntawm pneumatic dej tank. Ntev npaum li qhov ntws ntawm lub siab ruaj khov twj tso kua mis ua tau raws li qhov yuav tsum tau ua ntawm lub pneumatic dej tank, uas yog, qhov ntws ntawm lub twj tso kua mis siab stabilizing yuav tsum xav txog qhov muaj pes tsawg leeg ntawm cov tswj ntim ntawm pneumatic dej tank. Nyob rau lub sijhawm no, cov dej ntws ntawm lub siab ruaj khov twj tso kua mis yuav tsum raug txiav txim siab raws li tag nrho cov ntim ntawm cov cua thiab dej hauv lub tank ntawm cov dej pneumatic thiab cov ntim dej hauv lub tank. Cov dej tso tawm ntawm lub twj tso kua mis yuav tsum tsis pub tsawg dua 1.2 npaug ntawm qhov siab tshaj plaws ntawm cov kav dej hauv ib teev twg thaum lub tank nyob rau hauv lub siab tsis sib xws.
Cov kev cai ntawm cov kev cai siab tsis muaj cov kev cai uas yuav tsum tau nruab lub tshuab cua siab dej tank, tab sis tsis muaj lub tshuab cua siab dej tank, lub siab stabilizing twj tso kua mis pib nquag thiab yooj yim rau kev puas tsuaj; Nrog pneumatic dej tank, lub siab stabilizing twj tso kua mis pib nquag, qhov teeb meem yuav alleviated, thiab lub guarantee ntawm piecemeal siab stabilizing tej yam kev mob yuav ua tau zoo xav txog. Txawm li cas los xij, nws yog ib qho tsim nyog yuav tsum tau nce tus nqi ntawm pneumatic dej tank. Raws li ib txwm muaj, lub ntim ntawm lub pneumatic dej tank nruab nrog lub kaw lus tsis tas yuav tsum loj heev, thiab qhov ntim yuav tsum tsawg dua 50L. Shanghai tau muab tso ua ke tus qauv atlas ntawm kev teeb tsa pneumatic dej tank rau siab stabilizing twj tso kua mis txuam system, uas yog compiled los ntawm Shanghai Haiying machinery Hoobkas.
(3) Fragmentary scale: quasi tsis tshua muaj siab dej fragmentary (los yog ruaj khov tsis tshua muaj siab dej fragmentary) nrog siab stabilizing twj, xws li sab hauv tsev mus rau sab hauv tsev thiab sab nraum zoov. Sab hauv tsev quasi- cov dej tsis tshua muaj siab tsis sib haum xeeb, cov yeeb nkab siv cov yeeb nkab steel, thiab qhov sib txuas siv cov ntsia hlau buckle, flange lossis riveting kev twb kev txuas. Lub fragmentary to ntawm cov yeeb nkab network feem ntau tshwm sim nyob rau hauv lub sealing ib feem ntawm lub twj tso kua mis dej, thiab nws chav tsev yog unlimited kiag li. Sab hauv thiab sab nraum zoov quasi tsis tshua muaj dej siab yog fragmented, vim hais tias cov yeeb nkab sab nraum zoov adopts cam khwb cia hlau yeeb nkab, lub interface txais lub qhov (socket) kev twb kev txuas, thiab lub interface foob txais lub nplhaib roj hmab. Qhov ntsuas ntawm lub raj xa dej yog qhov loj, thiab qhov cuam tshuam qhov cuam tshuam rau qhov feem pua ntawm tag nrho cov xau. Tom qab kev tsim kho ballistic, cov av tseem yuav rov qab los. Qee lub sij hawm lub interface yog ntxiv nrog kev txhawb nqa pob zeb. Txawm hais tias muaj cov dej xau, nws yog qhov nyuaj rau kev ntsuas kev kho. Tag nrho cov no qhia tau hais tias thaum lub quasi qis - lub zog dej siab tau txais hauv tsev thiab sab nraum zoov, qhov ntws ntawm lub twj tso kua mis siab yuav tsum muaj qhov seem seem.
Feem ntau, qhov khiav ntawm lub siab stabilizing twj tso kua mis yuav tsum tau kho raws li qhov sib txawv
