Excavating machinery-a fault leh solution hman tlanglawn .

1. Excavator a chak lo .

Excavator-te fault tlangpui pakhat chu dinhmun pahnih-ah then theih a ni.

A chi khat chu lei laih chu chak lo mah se, engine chuan lirthei chu a tikhawtlai lo va; A phurrit chu a rit hle tih a hriat mai.

Engine a hold back loh chuan oil pump hian torque a absorb tlem a, engine load a light tih a tarlang bawk. Excavator hnathawh speed-ah hian thil danglam bik a awm loh chuan main pump-a output pressure sang ber, chu chu system overflow pressure chu emphasis-a enfiah tur a ni.

Overflow pressure tehna value chu a value tarlan aia hniam a nih chuan, he mechanism-a hydraulic circuit-a overload overflow valve setting value chu a dik lo tih a tilang a, chu chuan mechanism chu a hun hmain a luang chhuak a, a thawk chak lo hle a ni. Chutiang a nih chuan machine chu adjusting screw turn in a siamrem theih a ni.

A chi hnihna chu weak digging a ni a, boom emaw boom emaw chu a hnuai lam a thlen chuan engine chu a na hle emaw, a stall pawh a ni thei.

Hetiang malfunction hi engine speed sensing system chu a normal em tih enfiah hmasa phawt tur a ni. Inspection method hi a hmaa kan sawi tawh engine inspection method nen a inang a ni. A chunga detailed inspection leh troubleshooting kan neih hnuah engine speed sensing system chu normal function-ah a kir leh a, engine jamming phenomenon chu a bo a, excavator mechanical force chu a normal leh ang.
