Novel hydraulic energy accumulator control loop

The invention discloses a hydraulic energy accumulator working pressure control loop. The control loop is characterized by comprising a first electromagnetic valve, a first supercharger, a second electromagnetic valve, a third electromagnetic valve, a second supercharger, a fourth electromagnetic valve, a fifth electromagnetic valve, a third supercharger, a sixth electromagnetic valve, a seventh electromagnetic valve, an eighth electromagnetic valve, a fourth supercharger, a ninth electromagnetic valve, a tenth electromagnetic valve, a fifth supercharger, an eleventh electromagnetic valve, a twelfth electromagnetic valve, a sixth supercharger, a thirteenth electromagnetic valve, a hydraulic energy accumulator, a pressure sensor, an external hydraulic loop and a controller. The control loopcan effectively improve the problem of acute change of the outlet pressure of the hydraulic energy accumulator, reduces the impact on the main hydraulic loop by the hydraulic energy accumulator, andachieves higher practicabi
