Energy Saving on Hydraulic Systems of Excavators 821057
Hydraulic excavators can work on both powerful and fine jobs, which are executed safely. In conventional hydraulic systems of excavators, exhausted hydraulic energy losses were generated with fine control for attachments or with force limit.
Recently, variable displacement axial piston pumps equipped with energy saving controls have been developed and made available for hydraulic excavators.
With such energy saving controls which decrease mean fuel consumption of excavators, attachment drifts and noise are diminished, engine start during cold weather is made smoother and life of working fluid may be elongated.
