why the excavate speed is so slowly?

　　Even through the work rate of the engine motor part is high enough but maintain the normal running work mode at the same time, but the excavate work speed of excavator machine is very slowly, professional famous brands ESCO bucket tooth pin production supplier said these two phenomenon means the excavator is lack of driven force, and professional famous brands ESCO bucket tooth pin production supplier said due to most of the excavator hydraulic pump belongs to the piston pump, which would easily has the inner leakage phenomenon due to the inner pump accessories abrasion phenomenon after continue used for a certain time yet, but also because of the non evenness parameter, the total flowing quantity would become smaller, and due to the high oil temperature, the excavate motion would be finished with the low speed mode.

　　Professional famous brands ESCO bucket tooth pin production supplier said the solve method is right tear down the hydraulic pump but right regulate and set the setting parameter next, so the excavate speed would become normal again.
