6 FAQs about [Energy saving hydraulic system accumulator]
What is a hydraulic excavator energy saving system?
In order to address these issues, a hydraulic excavator energy saving system based on a three-chamber accumulator is proposed. Firstly, the conventional piston-type hydraulic accumulator is integrated with the hydraulic cylinder to form a three-chamber accumulator, which has a pressurizing function during energy storage.
Can a hydraulic excavator save energy?
Then, a hydraulic excavator energy saving system based on three-chamber accumulator is proposed, which can store and reuse the energy loss from throttling and overflow of the hydraulic system without changing the hydraulic system of the excavator.
Can energy-saving system be applied to other hydraulic equipment with dynamic changes?
The energy-saving system presented in this study can recover and reuse potential energy based on the hydraulic circuit illustrated in Fig. 3. Therefore, this system can also be applied to other hydraulic equipment with dynamic changes in potential energy within the working mechanism.
Do hydraulic accumulators provide sufficient energy?
To overcome the limitations of conventional hydraulic accumulators that fail to provide sufficient energy to meet the pressure requirements of actuators during energy recovery and reuse in excavators, a TCA configuration with pressurization functionality is proposed. The configuration of the TCA is depicted in Fig. 1.
Can a three-chamber accumulator save energy in excavator boom?
