Nomal mak na as bilong ol presa gej bilong paia pam autlet
Nomal mak bilong wanpela 'fire pump outlet pressure gauge' em i save stap namel long 0.8-1.4 MPa. Dispela mak i bihainim ol dispela profesenel standet:
1. Nesenel Standet Rikwaemen:Folem Atikel 5.1.6 bilong "Teknikel Spesifikasen bilong Paia Wara Saplai na Paia Haidrant Sistem" (GB 50974-2014), presa bilong autlet bilong paia pam i mas inapim presa bilong wok bilong ol masin bilong kilim paia long hap we sistem i no gutpela tumas. Jeneral disain veliu em 0.8-1.4 MPa.
2. Ol Praktikel Aplikesen Scenario:
- Ol liklik haus (olsem ol haus na ol liklik stua) i save gat liklik presa mak bilong 0.8 MPa.
- Ol bikpela bilding o ol bikpela haus i nidim presa bilong 1.0-1.4 MPa long daunim strong bilong paip na ol narapela narapela mak bilong antap.
3. Intanesenel Refrens:US NFPA 20 standet i tok tu olsem presa bilong paia pam i mas stap klostu long 1.0 MPa, we i wankain olsem ol standet bilong kantri.
Ol as na rot bilong stretim hevi bilong presa we i no stret
Sapos presa gej riding i stap ausait long nomol mak, skelim ol dispela samting:
1. Low Pressure (<0.8 MPa):
- As: Impeller i bagarap, paip i lik, pawa saplai voltej i no inap, o 'suction port' i pas.
- Solusen: Sekim sapos i gat 'leak', klinim filta, na senisim 'impeller' o apim presa sapos i gat nid.
2. High Pressure (>1.4 MPa):
- As: Autlet valv i no op gut, paip i pas, o presa gej i no stret.
- Solusen: Sekim 'valve status', kliarim paip, na stretim 'pressure gauge' oltaim.
Hau long Lukautim na Lukautim Gut Presa Gej
1. Kalibresen oltaim:Mekim 'calibration' long olgeta 6-pela mun bihainim "Pressure Instrument Verification Regulations" (JJG 52-2013) long lukim olsem ol riding i stret.
2. Inspeksen long olgeta de:Lukluk long 'pointer' long luksave sapos em i stap gut, sekim 'dial glass' sapos i gat ol bruk, na sekim sapos ol 'leak' i stap long ol join.
3. Linkage Test:Wantaim wanpela traim ran bilong paia proteksen sistem, mekim ol wok kondisen tru long sekim sapos presa bekim i bungim mak bilong disain.
Moa Toksave:Presa gej veliu em i wanpela mak tasol bilong helt bilong paia pam; ol i mas tingim tu wantaim ol narapela samting olsem 'flow rate' na 'current'. Olsem, sapos presa i nomol tasol 'flow rate' i no inap, ating wanpela hap bilong paiplain i pas. Em i gutpela long ol yusa i mas holim olgeta rekot bilong sekim ol paia pam na holim yet ripot bilong sekim we wanpela profesenel ogenaisesen i givim long bihain taim.
