Inlet Pipe hpe garan ginhka ai lam hpe tau hkrau tsun da ai lam ni
- Inlet pipe hta hka n-gun n nga ai rai yang, pump hpe shawng nnan bang ai shaloi prime galaw ra ai..
- Pump hpe jung ai shaloi, suction a npu hta n hkrat sum hkra, inlet pipe a matu grai n-gun ja ai rubber hose ni hpe hkum lang.
- Hka npu kaw nna n yawm htum 30cm daram hpe n-gun dat nna, hka htung hta n-gun n rawng hkra n-gun dat dat u. hpe n-gun dat dat u.
- Inlet pipeline kata na matut mahkai lam yawng hpe pat da ra ai. N-gun n law ai hpe shayawm kau ra ai, n rai yang pump gaw hka hpe atsawm sha n lu sha ai..
- Inlet pipe diameter gaw n yawm htum pump shang ai diameter hte maren sha rai ra ai, dai gaw hydraulic sum mat ai hte pru wa ai bungli galaw ai lam hta hkra machyi ai lam hpe pat shingdang na matu n-gun jaw ra ai.
- Dai hpe jai lang ai shaloi, hka n-gun a n-gun hpe sadi maja ra ai. Hka ntsa kaw na lagaw valve hpe n-gun n-jaw ra ai..
- Hka shang ai pipe a galu kaba ai gaw metre 10 jan jan mat ai shaloi, hka shang ai pipe baw gaw metre 4 jan mat ai shaloi, hka shang ai pipe a diameter gaw, pump a hka shang ai pipe diameter hta grau kaba ra ai.
- Pipeline hpe bang ai shaloi, pump hpe pipeline stress. n lawm ai hpe sadi u.
- laksan masa lam ni hta, ndai pump ni gaw lagaw n-gun n-nga ai sha bungli galaw lu ai, raitim, n-gun ja ai n-gun ni hpe pump. de n shang hkra, shang wa ai pipe ntsa kaw filter langai mi bang ra ai.
