Alasan Lambatnya Kecepatan Kerja Excavator

The main reason for the slow working speed of excavator is the engine power decline and hydraulic system leakage caused by the wear of all parts of the whole machine.

The hydraulic pump of the excavator is the plunger variable pump. After the working time is set, the internal hydraulic components of the pump (cylinder block, Douse, valve plate, nine-hole plate, turtle back, etc.) will inevitably produce excessive wear, which will cause internal leakage, and the parameters are not coordinated, resulting in insufficient flow, high oil temperature and slow working speed. At this time, it is necessary to overhaul the whole machine, repair and replace the parts that exceed the limit of wear.

But if the excavator does not suddenly slow down after working for a long time, the following aspects need to be checked.Pertama periksa apakah sekering sirkuit terbuka atau korsleting, kemudian periksa apakah tekanan pilot normal, dan kemudian lihat apakah katup kontrol servo - piston servo macet dan apakah distributor terputus, dan terakhir lepaskan pompa hidrolik untuk pengukuran data , untuk mengkonfirmasi masalah ekskavator.
