Sau pump hpe n-gun n jaw ai gaw, katsi ai chamber die casting machine. hte hkrum katut ai hkrat sum ai lam ni kaw na langai mi rai nga ai.
Ndai masa hpe mahtai jaw ai hku nna, lawu na jep joi ai lam ni hte sawk sagawn ai lam ni hpe galaw ra ai:
Relay n hkap la ai rai yang, ndai hpe yu ra ai:
1) Motor thermal relay gaw n kaja ai kun, hkra machyi ai kun?
2) Power circuit gaw multimeter. hte n-gun n rawng ai kun ngu ai hpe jep yu u.
3) Npawt nhpang hte hkring ai shara ni gaw shingra tara hku rai tim, hkang ai circuit gaw hpaw da ai rai yang .
4) Relay coil gaw hkra machyi ai kun, n hkra ai kun, multimeter .
{0}} Reley gaw hkap la ai rai yang , nang check galaw ra ai :
1) Die casting jak a sau pump gaw hten za mat ai kun?
2) Relay-to-motor line gaw normal rai kun?
3) Sau pump hkrat sum mat ai raitim, hpawng chyawm ai gaw grai n-gun ja ai raitim, lata hte coupling hpe gang je kau na matu loi ai, axial movement gaw3-5} mm daram hpe clearance galaw ra na re ..
