Wan pump pru ai n-gun shadawn jak ni a matu n-gun shadawn shadang hte npawt nhpang
Wan pump pru ai n-gun shadawn shadang a normal range gaw 0.8-1.4 MPa rai nga ai. Ndai range hpe lawu na hpaji masa ni hpe madung tawn nna galaw ai re.
1. Mungdan madang hta ra kadawn ai lam ni:"Wan hka jaw ai hte wan sat hka htung ni a matu hpaji masa" (GB 50974-2014) a daw kaba 5.1.6 hta tsun da ai hte maren, wan pump pru ai n-gun gaw, wan sat ai arung arai ni a bungli galaw ai n-gun ra kadawn ai n-gun hpe, wan sat jak a n kaja dik ai shara hta hkan sa ra ai. Madung hkrang shapraw ai manu gaw 0.8-1.4 MPa re.
2. Tatut jai lang mai ai lam ni:
- Npu -npu nta ni (ga shadawn, nta nta ni hte gat seng kaji ni) hta, npu na n-gun 0.8 MPa daram nga ai.
- Ntsa de-ntsa de na nta ni (sh) nta kaba ni hta pipe ninghkap ai lam hte tsaw ai shara shai hkat ai lam ni hpe tawt lai lu na matu 1.0-1.4 MPa lapran na n-gun ra ai.
3. Mungkan ting na Laika Buk:US NFPA 20 madang hta mung wan pump a n-gun hpe 1.0 MPa grup yin hta tawn da na matu hpaji jaw da ai, dai gaw mungdan kata na madang ni hte maren sha rai nga ai.
Abnormal Pressure a byin mai ai lam ni hte hparan ladat ni
Pressure gauge hti ai lam gaw, n-gun n-gun n-nga ai rai yang, lawu na hpe sawk sagawn yu u:
1. N-gun n law ai (<0.8 MPa):
- Hpa majaw: Impeller n-gun yawm mat ai, pipe hka pru ai, n-gun n law ai, shing nrai, suction port pat mat ai.
- Hpa baw hparan ladat: Hka lim ai hpe jep yu nna, filter hpe jasan jaseng nna, impeller hpe galai kau u (sh) ra ai rai yang pressure hpe jat bang u.
2. High Pressure (>1.4 MPa):
- Hpa majaw: Hprawng pru ai valve hpe tup hkrak n hpaw ai, pipe hpe pat da ai, shing nrai, pressure gauge hpe n mai lang ai.
- Hpa baw hparan ladat: Valve a masa hpe jep yu nna, pipe hpe jasan jaseng nna, pressure gauge hpe ayan gram lajang ra ai.
Pressure Gauge hpe gara hku atsawm sha yu reng nna gram lajang na
1. Galoi mung masat masa galaw ai:"Pressure Instrument hpe jep chyoi ai tara ni" (JJG 52-2013) hte maren shata kru shagu calibration galaw nna, hkrak hkrak hti lu na matu galaw ra ai.
2. Shani shagu jep joi ai lam:Pointer hpe ngang grin hkra yu nna, dial glass hta n-gun n rawng ai hpe yu nna, joint ni hta hka pru ai hpe yu u.
3. Matut mahkai chyam dinglik ai lam:Wan makawp maga ai ladat hpe chyam dinglik ai lam hte hpawn, n-gun atsam gaw hkrang shapraw ai manu hte htap htuk ai kun ngu ai hpe jep yu na matu, teng man ai bungli galaw ai masa hpe shingdaw yu u.
Jaw bang na matu:Pressure gauge manu gaw wan pump a hkam kaja lam hpe madun ai langai sha rai nga ai; dai hpe kaga parameters ni rai nga ai flow rate hte current ni hte rau mung myit yu ra ai. Ga shadawn, pressure gaw normal rai tim, flow rate n law ai rai yang, pipeline kata daw mi pat mat ai majaw rai na re. Wan pump hpe jep joi ai lam hpe tup hkrak hkan sa na matu hte hpaji ninghkring uhpung langai mi kaw nna shapraw ai jep joi ai lam hpe htawm hpang hta jai lang na matu tawn da na matu hpaji jaw da ai.
