Ibanga elijwayelekile kanye nesisekelo samageji okucindezela kokuphuma kwephampu yomlilo
Ububanzi obujwayelekile begeji ye-pressure gauge yepompo yomlilo ngokuvamile ingu-0.8-1.4 MPa. Lobu bubanzi busekelwe kumazinga alandelayo ochwepheshe:
1. Izidingo Ezijwayelekile Zikazwelonke:Ngokuvumelana ne-Article 5.1.6 "Izicaciso Zobuchwepheshe Zokuhlinzeka Ngamanzi Omlilo kanye Nezinhlelo Zokukhipha I-Fire Hydrant" (GB 50974-2014), ingcindezi yokukhipha iphampu yomlilo kufanele ihlangabezane nezidingo zengcindezi yokusebenza yemishini yokucisha umlilo endaweni engafaneleki kakhulu yesistimu. Ivelu yokuklama evamile ingu-0.8-1.4 MPa.
2. Izimo Zokusebenza Ezisebenzayo:
- Izakhiwo eziphakeme-eziphansi (njengezakhiwo zokuhlala nezindawo zezitolo ezincane) ngokuvamile ziba nomkhawulo wengcindezi ophansi ongu-0.8 MPa.
- Izakhiwo eziphakeme-eziphakeme noma izakhiwo ezinkulu zidinga ububanzi bokucindezela obungu-1.0-1.4 MPa ukuze kunqobe ukumelana namapayipi nokwehluka kokuphakama.
3. Inkomba yamazwe ngamazwe:Izinga le-US NFPA 20 liphinde lincome ukugcinwa kwengcindezi yepompo yomlilo ecishe ibe ngu-1.0 MPa, ngokuvamile ehambisana namazinga asekhaya.
Izimbangela Nezixazululo Ezingaba Khona Zengcindezi Engavamile
Uma ukufundwa kwegeji yokucindezela kungaphandle kwebanga elivamile, hlaziya okulandelayo:
1. Ingcindezi Ephansi (<0.8 MPa):
- Isizathu: Ukuguga kwe-impeller, ukuvuza kwamapayipi, amandla ogesi anganele, noma imbobo yokudonsa evalekile.
- Isixazululo: Hlola ukuvuza, hlanza isihlungi, bese ushintsha i-impeller noma ukhuphule ingcindezi uma kudingeka.
2. High Pressure (>1.4 MPa):
- Isizathu: I-valve yokuphumayo ayivuleki ngokugcwele, ipayipi livalekile, noma igeji ye-pressure gauge ayikho ekulinganisweni.
- Isixazululo: Hlola isimo sevalvu, sula ipayipi, futhi ulinganise njalo igeji yokucindezela.
Indlela Yokuqapha Nokugcina Isilinganiso Sokucindezela Ngokufanelekile
1. Ukulinganisa Okuvamile:Yenza ukulinganisa njalo ezinyangeni eziyisithupha ngokuvumelana "Nemithetho Yokuqinisekisa Insimbi Yokucindezela" (JJG 52-2013) ukuze uqinisekise ukufundwa okunembile.
2. Ukuhlolwa kwansuku zonke:Bheka iphoyinti lokuzinza, hlola ingilazi yokudayela ukuthi ayinamifantu, futhi uhlole ukuvuza emalungeni.
3. Ukuhlolwa Kokuxhumana:Kuhlanganiswe nokuqaliswa kwesilingo sesistimu yokuvikela umlilo, lilingisa izimo zokusebenza zangempela ukuze uqinisekise ukuthi impendulo yengcindezi iyahlangabezana yini nevelu yokuklama.
Inothi Elingeziwe:Inani legeji yokucindezela liyinkomba eyodwa kuphela yempilo yephampu yomlilo; kufanele futhi kucatshangelwe ngokuhambisana namanye amapharamitha afana nezinga lokugeleza kanye namanje. Isibonelo, uma ingcindezi ijwayelekile kodwa izinga lokugeleza linganele, ukuvaleka kancane kwepayipi kungase kube imbangela. Kunconywa ukuthi abasebenzisi bagcine amarekhodi aphelele okuhlolwa kwephampu yomlilo futhi bagcine umbiko wokuhlola okhishwe inhlangano yobungcweti ukuze usetshenziswe esikhathini esizayo.
