Excavator-a chak lohna tlangpui chungchanga harsatna awmte thlirletna .

1.Engine power hi a tawk a, a thawk tha hle a, mahse excavator hian a thawk zauh zauh a, digging power chak lo tak a nei bawk.

2.Excavator hydraulic pump te hi a tam zawk chu piston pump danglam thei an ni. Hun engemaw chen an thawh hnuah pump chhunga thil awmte chu a chhe vek lo thei a, chu chuan a chhung lam a ti chhuak thei a ni. Parameter hrang hrang data chu coordinate a ni lo va, chu chuan flow a tling tawk lo, oil temperature sang lutuk, speed slow lutuk, leh pressure sang tak din theih lohna a thlen a ni. Chuvangin, operation chu a slow a, a chak lo bawk. Chutiang thil a nih chuan, hydraulic pump chu data tehna atan harsatna a awm tih finfiah nan emaw, hman theih tawh loh part-te thlak emaw, a la hman theih tur part-te siam that emaw a ngai a ni. Reassembly hnuah circuit tinte parameters (pressure, flow rate, power leh variables, etc.) nena inmil turin debugging atan calibration bench-ah dah tur a ni.

3. Excavator-a hydraulic component pawimawh tak chu multi-way distribution valve a ni a, chutah chuan main safety valve, secondary valve, relief valve, oil replenishment valve, etc. Heng valve-te’n pressure an siam hian standard pressure a thlen theih loh chuan excavation chak lo a thlen thei a ni. Chu bakah, valve stem leh valve hole inkar gap chu a chhe lutuk avangin a lian lutuk a, valve stem chu a awmna hmasa berah a kir leh vek lo va, reversing pawh a awm lo a nih chuan, a chhunga leakage tam tak a awm ang a, chu chuan flow a tling tawk lo ang a, speed a ti hniam ang. Chutiang harsatna atan chuan multi-way distribution valve chu paih chhuah a, debugging atan test bench-ah thawn tur a ni. Valve zawng zawng pressure chu standard pressure-ah reset tur a ni a, valve stem leh valve hole inkar gap chu tihbo vek tur a ni.
