How to cancel the energy storage device of the hydraulic station

What are the limitations of hydraulic accumulators?

Conventional hydraulic accumulators suffer from two major limitations, the hydraulic system pressure varies with the quantity of energy stored and the energy density is significantly lower than other energy domains.

How dangerous is a hydraulic system?

Hydraulic systems are complex, so identifying stored energy locations in them can be difficult and dangerous. The energy of hydraulic fluid under pressure and the loads this energy supports are extremely hazardous. The accidental release of this energy has been the cause of many injuries and death throughout all industries.

What is a hydraulic err system?

In a hydraulic ERR system, a hydraulic accumulator with compressed nitrogen serves as the storage unit , which absorbs recoverable energy from the hydraulic actuator. Under the recovery condition, pressure oil discharged from the actuator is charged into the hydraulic accumulator .

Can electro-hydraulic energy-saving system save energy?

A electro-hydraulic energy-saving system is proposed for energy recovery and regeneration. A parametric rule-based strategy of the proposed system is developed for real-time control. The proposed energy-saving system prototype is equipped on a 23-ton hydraulic excavator. Experiments studies show that about 17.6% energy can be saving by this system.

How does a hydraulic system work?

The hydraulic energy from the system exerts force against the piston or bladder, which isolates the gas from the fluid. The nitrogen is compressed as the piston or bladder travels from the force.

Can a hydraulic excavator save energy?

A parametric rule-based strategy of the proposed system is developed for real-time control. The proposed energy-saving system prototype is equipped on a 23-ton hydraulic excavator. Experiments studies show that about 17.6% energy can be saving by this system. The system is evaluated from multiple perspectives of efficiency, performance and comfort.
