Influence of the excavator hydraulic system efficiency on the productivity

Popis výsledku v původním jazyce

This paper presents the experimental research of factors influencing the UDS 214 excavator efficiency. The hydraulic oil flow rate is measured in hydraulic circuits for controlling the moving of the bucket of the UDS 214 excavator. From the values measured in this way, the total power losses of the individual hydraulic circuits and their efficiencies are evaluated by calculations and measurements. Furthermore, the times of excavator cycles during a soil excavation and loading of the transport vehicle were measured. From the thus measured operating cycle times of the excavator, the average value of the operating cycle time was evaluated and from this average time the theoretical performance and then the operating performance of the given excavator in the given operational state of this excavator were calculated. Then, at the end of the paper, the individual calculated power losses and also the efficiencies of hydraulic circuits for controlling the moves of the excavator are evaluated. According to the findings, the swing hydraulic circuit of the excavator, which has the second highest power loss of 5,926 kW and its percentage in the average tested cycle time of the excavator is 48%, seems to be a suitable hydraulic circuit for the innovation.
