Energy Regeneration and Reuse of Excavator Swing System with Hydraulic Accumulator

The low-pressure side of the hydraulic motor can pull fluid from the tank through check valves 7 and 8. The flow direction is shown by a red line in Fig. 1 when the right side of the hydraulic motor is the output side. During the acceleration, DC 1 and DC 2 work in the left or right position based on the rotational direction of the hydraulic motor.

BOP Accumulator Requirements & Inspections

Volume of hydraulic fluid at 1,200 psi equals 1.67 gallons. Usable fluid operating under the above pressure; equals 6.67 – 1.67 = 5 gallons. Let''s assume that all the fluids volume required for BOP function as per IADC equal 250 gallons. So the total number of bottles required equal 250 / 5 which equal 50 bottles.
