Ntchito ndi ubwino wa pansi pa nthaka fire hydrant

Ntchito yachopozera moto pansi pa nthaka
Pakati pazigawo zakunja zopangira madzi apansi panthaka, chopopera chamoto chapansi panthaka ndi chimodzi mwa izo.Amagwiritsidwa ntchito makamaka popereka madzi kwa injini zozimitsa moto kapena zida zolumikizidwa mwachindunji ndi mipope yamadzi ndi mfuti zamadzi ndi kuzimitsa moto.Ndikofunikira kwapadera kwapadera kwa madzi akunja amoto.Kukhazikitsidwa mobisa, sikungakhudze maonekedwe ndi magalimoto a mzindawo.Amapangidwa ndivalavuthupi, chigongono, valavu kukhetsa ndi tsinde valavu.Ndichida chofunikira kwambiri chozimitsa moto m'mizinda, malo opangira magetsi, malo osungiramo zinthu ndi malo ena.Ndikofunikira makamaka m'matauni ndi malo okhala ndi mitsinje yochepa.Ili ndi mawonekedwe owoneka bwino, magwiridwe antchito odalirika komanso kugwiritsa ntchito bwino.Mukamagwiritsa ntchito ma hydrants apansi panthaka, ndikofunikira kukhazikitsa zizindikiro zowonekera.Zida zozimitsa moto zapansi panthaka zimagwiritsidwa ntchito kwambiri m'malo ozizira chifukwa sizosavuta kuonongeka ndi kuzizira.
Ubwino wa bomba lamoto pansi pa nthaka
Ili ndi zobisika zamphamvu, sizingakhudze kukongola kwa mzindawo, imakhala ndi chiwopsezo chochepa, ndipo imatha kuzizira m'malo ozizira.Ponena za madipatimenti ogwiritsira ntchito ndi oyang'anira, sikoyenera kupeza ndi kukonza, ndipo n'kosavuta kuikidwa m'manda, kutanganidwa ndi kukakamizidwa ndi kuyimitsidwa kwa magalimoto omanga.Ma hydrants ambiri apansi panthaka amafunika kutetezedwa ndi chipinda cham'madzi, ndipo ndalama zambiri zidzayikidwa.Pokonzekera maukonde a mapaipi apansi panthaka, zosadziwika zambiri zimakhala, ndipo kukonzekera kumakhala kovuta kwambiri.
The diameter of outletchopopera motosichiyenera kukhala chotsika kuposa φ 100mm, chifukwa cha kuwonjezeka kwa nyumba za m'tawuni ndi kuchulukana kwa anthu, vuto la kuzimitsa moto likuwonjezeka.Pofuna kuwonetsetsa kuti madzi azimitsidwa ndi madzi ozizimitsa moto, onetsetsani kuti m'mimba mwake ya hydrant yozimitsa moto ndi yosachepera φ 100mm.
Kutsegula ndi kutsekera kwa chopozera moto chapansi panthaka kudzakhala kofanana, ndipo kutsekedwa motsatira koloko ndikutsegulidwa motsatana.Chitsulo chosapanga dzimbiri chimasankhidwa ngati screw rod, ndipo mphira wa NBR umagwiritsidwa ntchito ngati kapu yosindikizira.The anti-corrosion in the cavity is to meet the ukhondo zizindikiro za madzi akumwa, ndipo ngakhale zofunika zofanana ndi valavu.
